Question 7

Which THREE techniques help prevent hitting governor limits when writing SOQL queries in Apex? Choose 3 answers.

Accepted Answer

Filtering queries using indexed fields (such as Id, Name, or external IDs) where possible.. Best practices include querying into collections, using bind variables, and filtering with indexed fields.

Answer

Omitting LIMIT clauses on large queries to ensure all records are fetched at once.

Answer

Placing SOQL queries inside helper methods called within loops.

Question 8

A developer is writing an Apex trigger and needs to optimize performance and prevent governor limit violations. Which TWO practices should the developer follow? (Choose two.)

Accepted Answer

Use trigger context variables like Trigger.new to process records in bulk.. Triggers must be bulkified to handle collections of records and queries/DML operations must be kept outside loops.

Answer

Place DML statements inside 'for' loops to ensure immediate database commits.

Answer

Use the 'webservice' keyword on helper methods called by triggers.

Answer

Execute a separate SOQL query for every single record in Trigger.new.

Question 9

A developer needs to write a secure SOQL query that prevents unauthorized data exposure by respecting both sharing rules and field-level security. Which TWO approaches can the developer combine to achieve this? (Choose two.)

Accepted Answer

Include the 'WITH SECURITY_ENFORCED' clause in the SOQL query.. Sharing rules are enforced via class keywords, while FLS can be enforced using WITH SECURITY_ENFORCED or Security.stripInaccessible.

Answer

Disable FLS checks in user profile settings before executing queries.

Answer

Execute queries inside an asynchronous @future method.

Answer

Use the 'without sharing' keyword on all transaction controllers.

Question 10

Which TWO criteria help a developer decide between using a Record-Triggered Flow and an Apex Trigger? (Choose two.)

Accepted Answer

Record-Triggered Flows provide declarative maintenance and faster build times for standard business logic.. Flow vs Apex decisions often depend on declarative preference, complexity, skill set, and architectural needs.

Answer

Apex Triggers cannot be deactivated without deploying code changes.

Answer

Record-Triggered Flows cannot run asynchronously.

Answer

Flows cannot execute before-save updates.

Question 11

Which TWO practices are considered best practices when writing Apex unit tests in Salesforce? (Choose two.)

Accepted Answer

Create all required test data within the test method or test setup method.. Using Test.startTest/stopTest and avoiding SeeAllData=true are essential Apex testing best practices.

Answer

Hardcode record IDs directly from the sandbox into assertions.

Answer

Query production records directly in every assertion to verify live system status.

Answer

Use @isTest(SeeAllData=true) on all test classes to ensure maximum compatibility with production data.

Question 12

Which THREE design patterns or tools help ensure secure coding practices regarding CRUD and FLS in Apex? Choose 3 options.

Accepted Answer

Using Security.stripInaccessible() before upserting data.. Security.stripInaccessible, WITH SECURITY_ENFORCED clause, and explicit Schema describe checks are valid methods.

Answer

Declaring every class with 'without sharing'.

Answer

Relying solely on Lightning Web Component HTML rendering tags.

Question 13

Which THREE best practices should a developer follow to avoid governor limits when writing SOQL queries in Apex? Choose 3 options.

Accepted Answer

Query only the specific fields needed rather than using SELECT *.. Best practices include avoiding queries inside loops, using bind variables, and querying only necessary fields.

Answer

Execute a separate SOQL query for every child record individually.

Answer

Always use SELECT FIELDS(ALL) to ensure all data is retrieved.

Question 14

Which TWO statements about SOQL relationship queries are true? Choose 2 options.

Accepted Answer

Child-to-parent queries use dot notation (e.g., Account.Name).. Parent-to-child queries use subqueries in parentheses, and child-to-parent queries use dot notation.

Answer

SOQL supports traversing up to 10 levels of parent relationships.

Answer

Parent-to-child queries use dot notation on the parent object.

Answer

Child-to-parent queries require subqueries.

Question 15

Which TWO of the following statements about Trigger.new and Trigger.old are accurate?

Accepted Answer

Trigger.old is available in update triggers. Trigger.new is always present on insert/update; Trigger.old is always present on update/delete.

Answer

Trigger.old is available in insert triggers

Answer

Trigger.newMap is available in before insert

Answer

Trigger.new is available in delete triggers

Question 16

Which THREE collections are available in Apex? (Choose three.)

Accepted Answer

Set. Apex provides three built-in collection types: List, Set, and Map.

Answer

Queue

Answer

Table

Question 17

Which THREE operations can cause an automatic roll back of an entire Apex transaction? Choose 3 options.

Accepted Answer

Exceeding a governor limit such as SOQL query count.. Unhandled exceptions, unhandled DML errors with allOrNone=true, and governor limit violations roll back the transaction.

Answer

Catching a DmlException inside a try-catch block.

Answer

Executing Database.insert(records, false) with partial failure.

Question 18

Which TWO best practices should a developer follow when writing bulkified Apex triggers? (Choose TWO.)

Accepted Answer

Perform DML statements and SOQL queries outside of loops by utilizing collections.. Bulkified triggers must operate on collections (Trigger.new) and avoid SOQL/DML inside loops.

Answer

Hardcode record IDs in trigger logic to route specific test accounts.

Answer

Use synchronous callouts directly inside before insert triggers.

Answer

Place SOQL queries inside loops to ensure every record gets fresh data.

Question 19

Which TWO statements are true regarding the Salesforce security model and Apex execution context? Choose 2 answers.

Accepted Answer

Apex code runs in system mode by default, ignoring object and field-level permissions.. Apex runs in system mode by default (ignoring FLS and CRUD), and sharing rules are only enforced if 'with sharing' is declared.

Answer

System mode ignores record-level sharing rules and user permissions entirely.

Answer

Apex code automatically enforces sharing rules unless declared 'without sharing'.

Answer

Profile permissions always override Apex system mode execution.

Question 20
