1. What is Apex

Ans: It is the in-house technology of salesforce.com which is similar to Java programming with object oriented concepts and to write our own custom logic.

2. What is S-Control ?
Ans: S-Controls are the predominant salesforce.com widgets which are completely based on Javascript. These are hosted by salesforce but executed at client side. S-Controls are superseded by Visualforce now.

3. What is a Visualforce Page ?
Ans: Visualforce is the new markup language from salesforce, by using which, We can render the standard styles of salesforce. We can still use HTML here in Visualforce. Each visualforce tag always begins with “apex” namespace. All the design part can be acomplished by using Visualforce Markup Language and the business logic can be written in custom controllers associated with the Page.

4. Will Visual force still supports the merge fields usage like S-control ?
Ans: Yes. Just like S-Controls, Visualforce Pages support embedded merge fields, like the {!$User.FirstName} used in the example.

5. Where to write Visualforce code ?
Ans: You can write the code basically in 3 ways.

1. setup->App Setup->Develop->Pages and create new Visulaforce page.

2. Setup -> My Personal Information -> Personal Information -> Edit check the checkbox development mode. When you run the page like this,https://ap1.salesforce.com/apex/MyTestPage. you will find the Page editor at the bottom of the page. You can write you page as well as the controller class associated with it, there it self.

3. Using EclipseIDE you can create the Visulaforce page and write the code.

6.What are Apex Governor Limits?

Governor limits are runtime limits enforced by the Apex runtime engine. Because Apex runs in a shared, multitenant environment, the Apex runtime engine strictly enforces a number of limits to ensure that code does not monopolize shared resources. Types of limits that Apex enforces are resources like memory, database resources, number of script statements to avoid infinite loops, and number of records being processed. If code exceeds a limit, the associated governor issues a runtime exception.

7. How to create and host S Control in Salesforce ?

9. How to schedule export or take the backup of salesforce?

http://shivasoft.in/blog/webtech/salesforce/backup-the-salesforce-data/

10. Do governor limits apply to sandbox instances?

Ans : Governor limits do apply to all Salesforce instances (trial, developer, production or sandbox environments). However code coverage and successful execution of test classes is only enforced when deploying to a production environment.

11. What is difference in ISNULL and ISBLANK?

ISNULL:

· Determines if an expression is null (blank) and returns TRUE if it is. If it contains a value, this function returns FALSE.

· Text fields are never null, so using this function with a text field always returns false. For example, the formula field IF(ISNULL(new__c) 1, 0) is always zero regardless of the value in the New field. For text fields, use the ISBLANK function instead.

· Multi-select picklist fields are never null in s-controls, buttons, and email templates, so using this function with a multi-select picklist field in those contexts always returns false.

· Empty date and date/time fields always return true when referenced in ISNULL functions.

· Choose Treat blank fields as blanks for your formula when referencing a number, percent, or currency field in an ISNULL function. Choosing Treat blank fields as zeroes gives blank fields the value of zero so none of them will be null.

· Merge fields can be handled as blanks, which can affect the results of components like s-controls because they can call this function.

· When using a validation rule to ensure that a number field contains a specific value, use the ISNULL function to include fields that do not contain any value. For example, to validate that a custom field contains a value of ’1,’ use the following validation rule to display an error if the field is blank or any other number: OR(ISNULL(field__c), field__c<>1)

ISBLANK:

· Determines if an expression has a value and returns TRUE if it does not. If it contains a value, this function returns FALSE.

· Use ISBLANK instead of ISNULL in new formulas. ISBLANK has the same functionality as ISNULL, but also supports text fields. Salesforce.com will continue to support ISNULL, so you do not need to change any existing formulas.

· A field is not empty if it contains a character, blank space, or zero. For example, a field that contains a space inserted with the spacebar is not empty.

· Use the BLANKVALUE function to return a specified string if the field does not have a value; use the ISBLANK function if you only want to check if the field has a value.

· If you use this function with a numeric field, the function only returns TRUE if the field has no value and is not configured to treat blank fields as zeroes.

12. Is it possible to write the Apex code from user Interface?

You can add, edit, or delete Apex using the Salesforce.com user interface only in a Developer Edition organization, a Salesforce.com Enterprise Edition trial organization, or sandboxorganization. In a Salesforce.com production organization, you can only make changes to Apex by using the Metadata API ,

deploycall, the Force.com IDE, or theForce.com Migration Tool. The Force.com IDE and Force.com Migration Tool are free resources provided by salesforce.com to support its users and partners, but are not considered part of our Services for purposes of the salesforce.com Master Subscription Agreement.

13. When you can’t add Time dependent action in Workflow rule?
You can’t add time-dependent actions to a rule if you choose Every time a record is created or edited.

14. What are the types of email templates available in salesforce.com?

1. Text

2. HTML with Letter Head

3. Custom HTML

4. Visual force

To study more on email templates, refer this article

15. What are the different Salesforce.com Editions and Limits?

Ans : check this URL

16. What is Roll up summary field in Salesforce?

Roll up summary field in salesforce calculates the Count, Sum, Min or Max of particular field of any child record. Thus, we can say that Roll up summary field can only be created on Master object. To read further, please check this URL

17. What will happen if the Account is deleted?

If the Account is deleted then Contact, Opportunity will also be deleted from Salesforce which are related to that Account.

From the database perspective, check below image of child relationships of Account:

Account Child relationship in salesforce

If we use schema builder, released in Winter 12 it would look like:

Account Contact and Opportunity of salesforce in schema builder

18. How many types of the relationship fields available in Salesforce?

Ans :

1. Master Detail

2. Many to Many

3. Lookup

4. Hierarchical (It is available only on User Object, we cannot create this relationship)

For further study read this.

19. How to create many to many relationships between object?

Creating many to many relationship in salesforce is little tricky. You cannot create this type of relationship directly. Follow below steps to create this type of relationship.

Create both objects which should be interlinked.

Create one custom object (also called as junction object), which should have autonumber as unique identification and create two master relationships for both objects, no need create tab for this object.

Now on both object, add this field as related list.

Check this article on blog to create many to many relationship in detail.

To study more in detail, please refer salesforce documents.

20. In Which sequence Trigger and automation rules run in Salesforce.com The following is the order salesforce logic is applied to a record.

1. Old record loaded from database (or initialized for new inserts)

2. New record values overwrite old values

3. System Validation Rules

4. All Apex “before” triggers (EE / UE only)

5. Custom Validation Rules

6. Record saved to database (but not committed)

7. Record reloaded from database

8. All Apex “after” triggers (EE / UE only)

9. Assignment rules

10. Auto-response rules

11. Workflow rules

12. Escalation rules

13. Parent Rollup Summary Formula value updated (if present)

14. Database commit

15. Post-commit logic (sending email)

Additional notes: There is no way to control the order of execution within each group above.

21. If one object in Salesforce have 2 triggers which runs “before insert”. Is there any way to control the sequence of execution of these triggers?

Ans : Salesforce.com has documented that trigger sequence cannot be predefined. As a best practice create one trigger per object and use comment blocks to separate different logic blocks. By having all logic in one trigger you may also be able to optimize on your SOQL queries.

22. How to delete the User from Salesforce?

Ans : As per now, salesforce does not allow to delete any user, however you can deactivate the user.

Read further…

23. How to delete the users data from Salesforce?

Ans : To delete the Users Data go to Setup | Administration Setup | Data Management | Mass Delete Record, from there select the objects like Account, Lead etc and in criteria select the users name and delete all records of that user related to particular object.

24. How to restrict the user to see any record, lets say opportunity?

Ans : set up opportunity sharing to be private. If both users are admins or have view all records on opportunity, then that overrides private sharing.

25. What is the difference between trigger.new and trigger.old in Apex – SFDC?

Ans :

Trigger.new :

Returns a list of the new versions of the sObject records.

Note that this sObject list is only available in

insert and

update triggers, and the records can only be modified in

beforetriggers.

Trigger.old :

Returns a list of the old versions of the sObject records.

Note that this sObject list is only available in

update and

delete triggers.

26. How to restrict any Trigger to fire only once ?

Ans:

Triggers can fire twice, once before workflows and once after workflows, this is documented at

http://www.salesforce.com/us/developer/docs/apexcode/ Content/ apex_triggers_order_of_execution.htm:

“The before and after triggers fire one more time only if something needs to be updated. If the fields have already been set to a value, the triggers are not fired again.”

Workaround:

Add a static boolean variable to a class, and check its value within the affected triggers.

view source print ?

1	public class HelperClass {
2	public static boolean firstRun = true;

3	}
4	trigger affectedTrigger on Account (before delete, after delete, after undelete) {

5	if(Trigger.isBefore){
6	if(Trigger.isDelete){

7	if(HelperClass.firstRun){
8	Trigger.old[0].addError('Before Account Delete Error');

9	HelperClass.firstRun=false;
10		}

11	}
12	}

}

27. What is difference between WhoId and WhatId in the Data Model of Task ?

Ans :

WhoID refers to people things. So that would be typically a Lead ID or a Contact ID
WhatID refers to object type things. That would typically be an Account ID or an Opportunity ID

Check Data Model of task here

28. Where is the option of the report for the “Custom Object with related object” and what are the condition to generate related reports?
Ans :

If the parent object is the standard object provided by the salesforce like “Account”, “Contact” then the report will be in there section with related custom object.
If both objects are the custom then the report will be in “Other Reports” Sections.

Following are the conditions to get the report of related objects:

· On both the objects, Reports option must be enable.

· The relationship between both of them must be “Master – detail relationship”.

Read this article, to get detailed idea on this topic.

29. How you can provide the User Login (Authentication) in Public sites created by Salesforce.

Answer : We can provide the authentication on public sites using “Customer Portal”.

This part of the interview question mainly focus on the dynamic Apex feature of thesalesforce.com .

30 : What is the dynamic Apex?
Ans :
Dynamic Apex enables developers to create more flexible applications by providing them with the ability to “Access sObject and field describe information”, “Write Dynamic SOQL Queries”, “Write Dynamic SOSL Queries” and “Dynamic DML”.

31 : How to get the list of all available sobject in salesforce database using Apex (Dynamic Apex)?
Ans:

view source print ?

1	Map<String, Schema.SObjectType> m = Schema.getGlobalDescribe();

32 : How to create instance of sobject dynamically? Normally the sobject is created like “Account a = new Account();”. But if you are in situation that you don’t know which sobject is going to be instantiated ? Means it will be decided at runtime, how you will handle it? Hint : Use Dynamic Apex.
Ans:

view source print ?

1	public SObject getNewSobject(String t)
2	{

3
4	// Call global describe to get the map of string to token.

5	Map<String, Schema.SObjectType> gd = Schema.getGlobalDescribe();
6

7	// Get the token for the sobject based on the type.
8	Schema.SObjectType st = gd.get(t);

9
10		// Instantiate the sobject from the token.

11	Sobject s = st.newSobject();
12

13	return s;
14	}

33 : How to get all the fields of sObject using dynamic Apex?
Ans:

view source print ?

1	Map<String, Schema.SObjectType> m = Schema.getGlobalDescribe() ;
2	Schema.SObjectType s = m.get('API_Name_Of_SObject') ;

3	Schema.DescribeSObjectResult r = s.getDescribe() ;
4	Map<String,Schema.SObjectField> fields = r.fields.getMap() ;

34 : How to get all the required fields of sObject dynamically?
Ans:
There is no direct property available in Apex dynamic API to represent the required field. However there is another way to know about it.
If any field have below three properties then it is mandatory field.

1. If it is Creatable

2. If it is not nillable and

3. If it does not have any default value

view source print ?

1	Map<String, Schema.SObjectType> m = Schema.getGlobalDescribe() ;
2	Schema.SObjectType s = m.get(so.apiName) ;

3	Schema.DescribeSObjectResult r = s.getDescribe() ;
4	Map<String,Schema.SObjectField> fields = r.fields.getMap() ;

5
6	for(String f : fields.keyset())

7	{
8	Schema.DescribeFieldResult desribeResult = fields.get(f).getDescribe();

9	if( desribeResult.isCreateable() && !desribeResult.isNillable() && !desribeResult.isDefaultedOnCreate() )
10		{

11	//This is mandatory / required field
12	}

}

35 : How to display error messages in the visualforce page ?
Ans:
In Apex use below code to create the error message for visualforce.

view source print ?

1	Apexpages.addMessage( new ApexPages.Message (ApexPages.Severity.ERROR, 'Required fields are missing. '));

in Visualforce page add below tag where you want to display the error message.

<apex:pageMessages ></apex:pageMessages>

36 : What is property in Apex? Explain with advantages.
Ans:
Apex mainly consist of the syntax from the well known programming language Java. As a practice of encapsulation in java we declare any variable as private and then creates the setters and getters for that variable.

view source print ?

1	private String name;
2	public void setName(String n)

3	{
4	name = n;

5	}
6	public String getName()

7	{
8	return name;

}

However, the Apex introduced the new concept of property from language C# as shown below:

view source print ?

1	public String name {get; set;}

As we can see how simple the code is and instead of using nearly 8 to 11 lines all done in 1 line only. It will be very useful when lots of member is declared in Apex class. It has another advantage in “number of lines of code” limit by salesforce which will drastically reduced.

37 : What is the controller extension ?
Ans:
Any apex class having a public constructor with Custom Controller or Standard Controller object as a single argument is known as controller extension.

38 : Explain the need or importance of the controller extension.
Ans:
Controller extension is very useful and important concept introduced by the salesforce recently. It gives the power to programmer to extend the functionality of existing custom controller or standard controller.
A Visualforce can have a single Custom controller or standard controller but many controller extensions.
we can say that the custom extension is the supporter of custom or standard controller.
Consider one example : If there is one controller written and used by the multiple visualforce pages and one of them needs some extra logic. Then instead of writing that logic to controller class (Which is used by many visualforce pages) we can create a controller extension and apply to that page only.

39 : How to read the parameter value from the URL in Apex?
Ans:
Consider that the parameter name is “RecordType”.

view source print ?

1	String recordType = Apexpages.currentPage().getParameters().get('RecordType');

40. What is Master Detail relationship and look up relationship in Salesforce?
Ans:
Master Detail relationship is the Parent child relationship. In which Master represents Parent and detail represents Child. If Parent is deleted then Child also gets deleted. Rollup summary fields can only be created on Master records which will calculate the SUM, AVG, MIN of the Child records.
Look up relationship is something like “has-a” (Containership) relationship. Where one record has reference to other records. When one record is deleted then there is no impact on other records.

41. Can we convert the lookup relationship to Master Detail relationship?
Ans:
We can convert the lookup relationship to master detail relationship if and only if all the existing record has valid lookup field.

42. In How many way we can invoke the Apex class?
Ans:

1. Visualforce page

2. Trigger

3. Web Services

4. Email Services

43. Can we create Master Detail relationship on existing records?
Ans:
No. As discussed above, first we have to create the lookup relationship then populate the value on all existing record and then convert it.

44. How validation rules executed? is it page layout / Visualforce dependent?
Ans :
The validation rules run at the data model level, so they are not affected by the UI. Any record that is saved in Salesforce will run through the validation rules.

45. What is the difference between database.insert and insert ?
Ans:
insert is the DML statement which is same as database.insert. However, database.insert gives more flexibility like rollback, default assignment rules etc. we can achieve the database.insert behavior in insert by using the method setOptions(Database.DMLOptions)
Important Difference:

· If we use the DML statement (insert), then in bulk operation if error occurs, the execution will stop and Apex code throws an error which can be handled in try catch block.

· If DML database methods (Database.insert) used, then if error occurs the remaining records will be inserted / updated means partial DML operation will be done.

46. What is the scope of static variable ?
Ans:
When you declare a method or variable as static, it’s initialized only once when a class is loaded. Static variables aren’t transmitted as part of the view state for a Visualforce page.

Static variables are only static within the scope of the request. They are not static across the server, or across the entire organization.

47. Other than SOQL and SOSL what is other way to get custom settings?
Ans:
Other than SOQL or SOSL, Custom seting have there own set of methods to access the record.
For example : if there is custom setting of name ISO_Country,

view source print ?

1	SO_Country__c code = ISO_Country__c.getInstance(‘INDIA’);
2	//To return a map of data sets defined for the custom object (all records in the custom object), //you would use:

3	Map<String,ISO_Country__c> mapCodes = ISO_Country__c.getAll();
4	// display the ISO code for India

5	System.debug(‘ISO Code: ‘+mapCodes.get(‘INDIA’).ISO_Code__c);
6	//Alternatively you can return the map as a list:

7	List<String> listCodes = ISO_Country__c.getAll().values();

48. What happen if child have two master records and one is deleted?
Ans :
Child record will be deleted.

read more in this article.

49. What is Difference in render, rerender and renderas attributes of visualforce?
Ans:
render – It works like “display” property of CSS. Used to show or hide element.
rerender – After Ajax which component should be refreshed – available on commandlink, commandbutton, actionsupport etc.
renderas – render page as pdf, doc and excel.

50. What is Scheduler class in Apex?
Ans:
The Apex class which is programed to run at pre defined interval.
Class must implement schedulable interface and it contains method named execute().
There are two ways to invoke schedular :

1. Using UI

2. Using System.schedule

The class which implements interface schedulable get the button texted with “Schedule”, when user clicks on that button, new interface opens to schedule the classes which implements that interface.
To see what happened to scheduled job, go to “Monitoring | Scheduled jobs “

Example of scheduling :

view source print ?

1	scheduledMerge m = new scheduledMerge();
2	String sch = '20 30 8 10 2 ?';

3	system.schedule('Merge Job', sch, m);

To see how to make crone job string – refer this URL.

51. Explain Permission sets released in Winter 12.
Ans :
A permission set is a collection of settings and permissions that give users access to various tools and functions. The settings and permissions in permission sets are also found in profiles, but permission sets extend users’ functional access without changing their profiles. For example, to give users access to a custom object, create a permission set, enable the required permissions for the object, and assign the permission set to the users. You never have to change profiles, or create a profile for a single use case. While users can have only one profile, they can have multiple permission sets.

52. What is the difference between External ID and Unique ID?
Ans:
External ID
This is a field that usually references an ID from another (external) system. For instance, if the customer has an Oracle Financials system that they will be linking with salesforce.com, it may be easier for them to be able to refer to the Oracle ID of account records from within salesforce. So they would create an external ID in salesforce.com and they would load the Oracle ID into that field for each account. They can then refer to that ID field, rather than thesalesforce.com id.

Additionally, if you have an external ID field, the field becomes searchable in the sidebar search. You also can use the upsert API call with the extenal ID to refer to records.

You can have multiple records with the same external ID (though it is not reccomended, as it will defeat the purpose of the external id) .

External Id available for Text, Number and Email field types.

External Id is used in upsert operations.

· If external id is absenor not matched then insert happens.

· If external id matched once then record will be updated.

· If external id is matched multiple times then error occurs.

Unique ID field

This is a setting for the field that will prevent you from using the same value in multiple records for the unique field. So if I create a 5 character text field and make it unique, and I create a record with the value “12345″ i will not be able to create another record with that same value in the unique field. If i try to do so, I will get an error saying that the value is already in use.

Often, External Ids are set with the unique property so that the IDs will be unique to each record.

Salesforce – External Id option while creating field

53. How to get the picklist value in Apex class?
Ans :
Using Dynamic apex, we can achieve this.on object of type pickilist, call getDescribe(). then call the getPicklistValues() method. iterate over result and create a list. bind it to <apex:selectOptions>.

54. What are the types of controller in visual force?
Ans :
There are basically two types of Controller in Visual force page.

1. Standard Controller and

2. Custom Controller

55. How many Controllers can be used on single VF page?
Ans :

Only one controller can be used salesforce. Other than them, Controller extension can be used. There may be more than one Controller extention.
Example :

view source print ?

1	<apex:page standardController="Account"
2	extensions="ExtOne,ExtTwo" showHeader="false">

3	<apex:outputText value="{!foo}" />
4	</apex:page>

if ExtOne and ExtTwo, both have the method getFoo() then the method of ExtOne will be executed.

A controller extension is any Apex class that contains a constructor that takes a single argument of type ApexPages.StandardController or CustomControllerName, where CustomControllerName is the name of a custom controller that you want to extend.

56. Explain System.runAs()
Ans :
Generally, all Apex code runs in system mode, and the permissions and record sharing of the current user are not taken into account. The system method, System.runAs(), lets you write test methods that change user contexts to either an existing user or a new user. All of that user’s record sharing is then enforced. You can only use runAs in a test method. The original system context is started again after all runAs() test methods complete.
Example :

view source print ?

1	System.runAs(u) {
2	// The following code runs as user 'u'

3	System.debug('Current User: ' + UserInfo.getUserName());
4	System.debug('Current Profile: ' + UserInfo.getProfileId()); }

5	// Run some code that checks record sharing
6	}

57. Explain Test.setPage().
Ans:
It is used to set the context to current page, normally used for testing the visual force controller.

58. What is the custom settings ?
Ans :
Custom settings are similar to custom objects and enable application developers to create custom sets of data, as well as create and associate custom data for an organization, profile, or specific user. All custom settings data is exposed in the application cache, which enables efficient access without the cost of repeated queries to the database. This data can then be used by formula fields, validation rules, Apex, and the Web services API.

59. Types of the custom settings?
Ans :
List Custom Settings
A type of custom setting that provides a reusable set of static data that can be accessed across your organization. If you use a particular set of data frequently within your application, putting that data in a list custom setting streamlines access to it. Data in list settings does not vary with profile or user, but is available organization-wide. Examples of list data include two-letter state abbreviations, international dialing prefixes, and catalog numbers for products. Because the data is cached, access is low-cost and efficient: you don’t have to use SOQL queries that count against your governor limits.

Hierarchy Custom Settings
A type of custom setting that uses a built-in hierarchical logic that lets you “personalize” settings for specific profiles or users. The hierarchy logic checks the organization, profile, and user settings for the current user and returns the most specific, or “lowest,” value. In the hierarchy, settings for an organization are overridden by profile settings, which, in turn, are overridden by user settings.

60. Difference between SOSL and SOQL in Salesforce ?
Ans :

SOSL	SOQL
stands for "Salesforce object search language".	stands for "Salesforce object query language".
Works on multiple object at a same time.	Need to write different SOQL for different object.
All fields are already text indexed.	SOQL against same field will be slow.
Cannot used in Triggers. Can only be used in Apex class and anonymous block.	Can be used in Apex class and Triggers.

61. How to round the double to two decimal places in Apex?
Ans:

view source print ?

1	Decimal d = 100/3;
2	Double ans = d.setScale(2) ;

62.In Profile settings, what is difference between “Modify All Data” and “Modify All” ?
Ans:
Modify All Data : Create, edit, and delete all organization data, regardless of sharing settings.
Modify All : Give All (Read, Create, Add, Delete) permission to selected Object.

63. If i want record level access then what should i use from Salesforce security model?
Ans: Manual Sharing

63. If i want Object level access then what should i use from Salesforce security model?
Ans: Profile

64. In OWD (Organization wide sharing), can i change the setting “Grant Access Using Hierarchies” for Standard Objects ?
Ans: You cannot change it for Standard Objects However for Custom Objects its possible.

65. What is Mandatory while creating User, Role or Profile?
Ans : Its Profile.

66. In case of Master-Detail relationship, on Update of master record can we update the field of child record using workflow rule?
Ans: No

67. In case of Master-Detail relationship, on Update of child record can we update the field of Parent record using workflow rule?
Ans: Yes, the Master fields are also available for “Criteria evaluation”.

68. While setting OWD (Organization wide sharing), can we change/modify the setting of child record in case of Master-Detail relationship?
Ans: No, Child record is controlled by the Parents setting.

69. What is the need of “Custom Controller” in Visualforce as everything can be done by the combination of Standard Controller + Extension class.
Ans :

· Sharing setting is applied on standard object/extension by default; In case we don’t want to apply sharing setting in our code then Custom controller is only option.

· It is possible that the functionality of page does not required any Standard object or may require more than one standard object, then in that case Custom controller is required.

70. In class declaration if we don’t write keyword “with sharing” then it runs in system mode then why keyword “without sharing” is introduced in apex?
Ans:
Lets take example, there is classA declared using “with sharing” and it calls classB method. classB is not declared with any keyword then by default “with sharing” will be applied to that class because originating call is done through classA. To avoid this we have to explicitly define classB with keyword “without sharing”.

Part 8 interview question is going to be around reports and profiles related question as i have seen this type of questions in lot of interviews.

71. If user doesn’t have any right on particular record and have only read level access at object level. Can he change the record owner?
Ans : Yes. In profile, there is setting for “Transfer Record”.

72. In Which Scenario share object “MyCustomObject__share” is not available/created for custom object “MyCustomObject” ?
Ans: The object’s organization-wide default access level must not be set to the most permissive access level. For custom objects, this is Public Read/Write. For more information, see Access Levels. This object is used for creating Apex based sharing.

73. How to hide the “App Setup” Menu from user’s setup page?
Ans : In Profile, remove access “View Setup and Configuration”.

74. While creating new profile for user, which existing profile should be copied?
Ans: If the new user is not System administrator then copy from “Standard User” profile.

75. Who can run reports?
Ans : Users with permission “Run Report” and access to report folder can only run the report.
