Salesforce PDI Online Questions & Answers

• Question 121:

  A business has a proprietary Order Management System (OMS) that creates orders from its website and fulfills the orders. When the order is created in the OMS, an integration also creates an order record in Salesforce and relates it to the contact as identified by the email on the order. As the order goes through different stages in the OMS, the integration also updates it in Salesforce.

  The business notices that each update from the OMS creates a new order record in Salesforce.

  Which two actions should prevent the duplicate order records from being created in Salesforce? Choose 2 answers

  A. Use the order number from the OMS as an external ID.
  B. Ensure that the order number in the OMS is unique.
  C. O Use the email on the contact record as an external ID.
  D. O Write a trigger on the Order object to delete the duplicates.
  A. Use the order number from the OMS as an external ID.
  B. Ensure that the order number in the OMS is unique.

  ---

  Explanation

  A: Using the order number as an external ID ensures Salesforce can identify and update existing records instead of creating duplicates during updates.

  B: Ensuring the order number is unique in the OMS guarantees that there will not be multiple records in Salesforce corresponding to a single order.

• Question 122:

  A software company is using Salesforce to track the companies they sell their software to in the Account object. They also use Salesforce to track bugs in their software with a custom object, Bug__c.

  As part of a process improvement initiative, they want to be able to report on which companies have reported which bugs. Each company should be able to report multiple bugs and bugs can also be reported by multiple companies.

  What is needed to allow this reporting?

  A. Roll-up summary field of Bug_c on Account
  B. Master-detail field on Bug_c to Account
  C. Lookup field on Bug_c to Account
  D. Function object between Bug__c and Account
  D. Function object between Bug__c and Account

  ---

  Explanation

  Many-to-Many Relationship:

  To track which companies (Accounts) report which bugs and allow multiple associations for both, a junction object is needed.

  This junction object will have two master-detail relationships: one to Bug__c and one to Account.

  Why Not Other Options?

  A. Roll-up summary field: Not suitable for many-to-many relationships.

  B. Master-detail field on Bug__c to Account: Creates a one-to-many relationship, not many-to- many.

  C. Lookup field on Bug__c to Account: Still creates a one-to-many relationship, not many-to- many.

• Question 123:

  A developer wants to prevent users from saving a record when a required condition is not met.

  Which declarative feature is most appropriate?

  A. Validation rule
  B. Workflow rule
  C. Process Builder
  D. Approval process
  A. Validation rule

  ---

  Explanation

  Validation rules are specifically designed to prevent records from being saved when defined conditions evaluate to true. They provide immediate feedback to users and enforce data integrity at the database level, regardless of how the record is created or updated. Workflow rules and Process Builder can automate actions after a record is saved but do not block the save operation. Approval processes manage record approval flows and are not intended for enforcing simple field-level conditions.

• Question 124:

  Which statement describes the execution order when triggers are associated to the same object and event?

  A. Triggers are executed in the order they are modified.
  B. Trigger execution order cannot be guaranteed.
  C. Triggers are executed alphabetically by trigger name.
  D. Triggers are executed in the order they are created.
  B. Trigger execution order cannot be guaranteed.

  ---

  Explanation

  When multiple triggers are associated with the same object and event, Salesforce does not guarantee the order of execution. This is why it is a best practice to consolidate all logic into a single trigger per object and control execution order using helper classes.

• Question 125:

  The values 'High', 'Medium', and 'Low' are identified as common values for multiple picklists across different objects.

  What is an approach a developer can take to streamline maintenance of the picklists and their values, while also restricting the values to the ones mentioned above?

  A. Create the Picklist on each object and use a Global Picklist Value Set containing the values.
  B. Create the Picklist on each object as a required field and select "Display values alphabetically, not in the order entered".
  C. Create the Picklist on each object and add a validation rule to ensure data integrity.
  D. Create the Picklist on each object and select "Restrict picklist to the values defined in the value set".
  A. Create the Picklist on each object and use a Global Picklist Value Set containing the values.

  ---

  Explanation

  A Global Picklist Value Set allows the same set of picklist values to be shared across multiple objects, making maintenance easier and ensuring consistency.

  Why not other options?

  B: Alphabetical ordering does not ensure consistent value maintenance across objects.

  C: Validation rules do not streamline picklist value maintenance.

  D: Restricting picklist values helps ensure data integrity but does not streamline maintenance across objects.

• Question 126:

  A developer writes a SOQL query that returns more than 50,000 records, causing a runtime exception.

  Which governor limit is being exceeded?

  A. DML statements limit
  B. SOQL queries limit
  C. Total rows retrieved by SOQL
  D. CPU time limit
  C. Total rows retrieved by SOQL

  ---

  Explanation

  Salesforce enforces a governor limit on the total number of records that can be retrieved by SOQL queries in a single transaction. In synchronous Apex, this limit is 50,000 rows. If a query or combination of queries exceeds this threshold, a runtime exception is thrown. This limit is separate from the number of SOQL queries allowed and is intended to prevent excessive memory consumption. To handle large data volumes, developers can use asynchronous processing such as Batch Apex, which provides higher limits and processes records in smaller chunks.

• Question 127:

  Which two process automations can be used on their own to send Salesforce Outbound Message? Choose 2 answers

  A. Process Builder
  B. Workflow Rule
  C. Flow Builder
  D. Strategy Builder
  B. Workflow Rule
  C. Flow Builder

  ---

  Explanation

• Question 128:

  A developer must provide custom user interfaces when users edit a Contact in either Salesforce Classic or Lightning Experience.

  What should the developer use to override the Contact's Edit button and provide this functionality?

  A. A Lightning component in Salesforce Classic and a Lightning component in Lightning Experience
  B. A Lightning page in Salesforce Classic and a Visualforce page in Lightning Experience
  C. A Visualforce page in Salesforce Classic and a Lightning page in Lightning Experience
  D. A Visualforce page in Salesforce Classic and a Lightning component in Lightning Experience
  D. A Visualforce page in Salesforce Classic and a Lightning component in Lightning Experience

  ---

  Explanation

  To override the Edit button in both Salesforce Classic and Lightning Experience:

  Use a Visualforce page for Salesforce Classic.

  Use a Lightning component for Lightning Experience by configuring the Lightning override.

• Question 129:

  How can a developer implement this feature?

  A. Build an account assignment rule.
  B. Build a workflow rule.
  C. Build a flow with Flow Builder.
  D. Build an account approval process.
  C. Build a flow with Flow Builder.

  Explanation

• Question 130:

  Universal Containers is building a recruiting app with an Applicant object that stores information about an individual person and a Job object that represents a job. Each applicant may apply for more than one job.

  What should a developer implement to represent that an applicant has applied for a job?

  A. Junction object between Applicant and Job
  B. Lookup field from Applicant to Job
  C. Master-detail field from Applicant to Job
  D. Formula field on Applicant that references Job
  A. Junction object between Applicant and Job

  ---

  Explanation

  A. Junction object between Applicant and Job:

  Since an Applicant can apply for multiple Jobs and each Job can have multiple Applicants , this is a many-to-many relationship .

  Salesforce requires a junction object to represent many-to-many relationships. The junction object will have two master-detail relationships: one to the Applicant object and one to the Job object.

  The junction object could be named something like JobApplication__c, which would represent the specific instance of an applicant applying for a particular job.

  Why this is the correct approach?

  A junction object allows for robust data management and reporting capabilities in a many-to- many relationship.

  This design ensures that each combination of applicant and job is captured as a unique record in the JobApplication__c junction object.

  It also allows storing additional details about the application, such as application date, status, and feedback.

  Why not the other options?

  B. Lookup field from Applicant to Job:

  A lookup field creates a one-to-many relationship. While an Applicant could reference one Job, it does not support the many-to-many relationship required in this scenario.

  C. Master-detail field from Applicant to Job:

  A master-detail relationship is a one-to-many relationship, which is unsuitable for a many-to- many relationship. Additionally, you cannot have two master-detail fields on a single object to connect Applicant and Job directly.

  D. Formula field on Applicant that references Job:

  A formula field cannot establish relationships between records or represent a many-to-many relationship. It is only for computed fields.
