Free Salesforce Platform Developer I Practice Test

Developers can develop applications only in developer edition orgs. But other orgs, such as the Enterprise Edition, also support development and coding functionalities in their Sandboxes.

The best way to avoid Governor Limits is to bulkify your code by using sets, lists, and Maps. You must also keep your SOQL queries outside loops.

Inner classes do not inherit the sharing setting of the container class. Both the inner and outer classes can be declared as "with sharing".

LastName is a mandatory field on the contact object, so it must be populated when a contact is inserted.

The Boolean inherits its value from the object.

The New Lighting component framework comes with a new responsive design called LDS (Lightning Design System) and has a JavaScript driven architecture.

Visualforce tags are similar to the JSP tag library that carry the metadata information.

The developer can either use Schema.PickListEntry returned by Case.Status.getDescribe().getPicklistValues() or Schema.RecordTypeInfo returned by Case.SObjectType.GetDescribe().getRecordTypeInfos().

We can use an Apex method to obtain the ID from the page URL. Usually, we use a constructor to call it because every time the page loads, the constructor is called first.

You can use related merged fields to obtain the data from the parent record. The relative fields are prepended to __r .

You can modify the custom Visualforce pages in unmanaged packages; the code in Managed Packages cannot be modified. Alternatively, you can also create a customized Visualforce page with an Apex controller to provide the required input fields.

It is advisable to upload all the images, Stylesheets, and JavaScript files as Static resources because that enables the files to load faster.

Standard controllers have limited functionalities. To fetch records of grandchildren, SOQL query needs to be used in a controller extension.

The "view state" inspector displays components contributing to it only when the tag is used. It must be enabled on a user profile.

Just like Java, Apex is also an object oriented programming language. With its Cloud compatibility, it has now become an on-demand programming language.

When the user updates the record, the Apex Trigger will keep firing, causing Trigger recursion. To avoid this, follow Trigger best practices.

Since the ReportsTo field is to be populated after the Account and Department field values are provided or updated, before insert and before update Triggers would be required.

The code fails because a SOQL query is located inside the "for" loop and SOQL Query Governor Limit has been hit.

This is the correct order of a Trigger Execution. To see the full order, check the given link: _x000D__x000D_https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_triggers_order_of_execution.htm

Apex transactions are automatically rolled back if they are not successful.

Use custom controllers when you don't require the standard functionalities of the object or if the page references more than one primary object.

Since the first "if" condition was satisfied, the value of x is "B".

The multiple options selected in the picklist appear as a String with each value separated by a semicolon.

One of the best practices for Triggers is to bulkify the code. Set and map data structures are critical for successful coding of bulk triggers.

isCreatable is used to check if a user has access to create records for an object.

A variable can be defined at any point in a block. Parallel blocks can use the same variable name. However, sub-blocks cannot reuse the variable name of a parent block.

One of the methods of the StandardSetController class is getListViewOptions.

getDMLStatements method shows you the number of DML calls that have been used so far._x000D__x000D_ getLimitsDMLStatements shows you the total number calls that can be made.

Custom controllers don't have a parameterized constructor.

This is the correct syntax.

We can override the standard functionality of the standard buttons through Visualforce pages which use the same object's standard controller.

The user will see only masked characters, but can enter a new value and save it.

To meet the specified requirement, the Position and Candidate objects need to be linked through a "many to many" relationship. In Salesforce, this is accomplished by creating a junction object.

Since the Grant Access using Hierarchies is un-checked, no user above the owner of the record in role hierarchy will be able to see the record._x000D__x000D_ Users below the owner of the record in the role hierarchy are not allowed to see it anyway._x000D__x000D_ OWD is private, hence only owners have the access to see the record.

Radio buttons cannot be created in Salesforce using standard functionality. A Visualforce page is needed to show radio buttons on the page.

VLOOKUP can be used to validate data with the records in a custom object.

Custom validations are written as part of the logic in a "before insert" Trigger.

Schema Builder is a good tool to view and make corrections in your database. But to delete a custom field, you need to first remove all the references of the field.

Custom roll-up summary fields can be created using Standard Object relationships on Opportunity using Opportunity Product records, on Campaign using Campaign Member records, and on Account using Opportunity records.

In a master-detail relationship, the child object inherits all the properties of the master object.

A child record once linked to a master record using a master-detail relationship cannot be re-parented unless "re-parenting allowed" checkbox is checked on the field definition level.

Account data passed to the test class should be modified according to the modified validation.

With a lookup relationship, child records can have distinct owners. With Master-Detail relationship, parent records become the owner of the child record. Since both Account and Warehouse are independent entities, there will be a lookup relationship between them.

Since an engine can have multiple parts and a component can be a part of multiple engines, a Junction object needs to be created.

For security purposes, Salesforce provides encryption fields to store information. These fields have their own features. For more detail, refer the Salesforce reference documents: _x000D_https://help.salesforce.com/HTViewHelpDoc?id=fields_about_encrypted_fields.htm&language=en_US

Select the Override Log Triggers checkbox for the Trigger to get the Debug Logs out.

You need to set the Debug Log level to least DEBUG to be able to view user-generated debug statements.

The Force.com platform provides a code version control system. It also allows you to upgrade applications without losing customizations.

Force.com Metadata API and Force.com IDE provide access through the metadata components.

Debug Logs record details for Apex, Visualforce pages, Callouts, and other entities but do not capture certain items such as JavaScript and formula fields.

Administrator Setup allows you to make changes to Salesforce.

Users with the View Setup and Configuration permission can view all the dashboards scheduled to refresh for your organization on the All Scheduled Jobs page. To view the All Scheduled Jobs page, go to Setup, enter Scheduled Jobs in the Quick Find box, and select Scheduled Jobs.

When using the Force.com IDE, we have to create a project, import the database, and build schema in the IDE itself._x000D__x000D_ Schema Explorer can also be used to check the schema of the object.

These actions add up to the Governor Limits. So you should be careful while using them.

These are the different ways in which Test Classes can be executed in Salesforce.

Use @TestVisible annotation to make the private methods or variables visible to test classes.

This is the correct process for testing any functionality in Apex.

Taking the test data from the user input takes up a lot of time.

As a Full Copy Sandbox is a replica of the production org, they can have identical Salesforce record IDs.

Process Builder can be used to update child records when parent records are updated.
