Start Developer Fundamentals PracticeA developer needs to retrieve Account records along with their associated Contacts in a single query. Which query syntax is correct?
Explanation: The correct syntax for a parent-to-child relationship query in SOQL is to use the plural relationship name (e.g., Contacts) within a subquery in the SELECT clause. Option D is the only syntactically correct SOQL query.
An Apex trigger needs to query related Account records for a list of newly inserted Contact records. What is the most robust way to handle the relationship query in SOQL to avoid governor limits?
Explanation: To avoid hitting Salesforce governor limits (specifically the limit of 100 SOQL queries in a synchronous transaction), you must never query inside a for loop. Instead, iterate through the trigger collection to extract the related parent IDs into a Set, and then perform a single bulkified SOQL query using the IN operator.
Which collection method is used to add all elements from one Set into another Set in Apex?
Explanation: The addAll() method is available on Set, List, and Map collections to add multiple elements at once.
What is the correct way to declare a constant variable in Apex?
Explanation: In Apex, constants are typically declared using the 'static final' keywords for class-level variables, or 'final' for local variables. Option B correctly uses 'final'.
A developer needs to retrieve 10 Account records starting from the 21st record to implement pagination in a custom component. Which SOQL clause should be used?
Explanation: SOQL supports pagination using LIMIT and OFFSET clauses.
