NEW QUESTION # 124
The test method above calls an @future method that increments the Number_of_Times_Viewed__c value. The assertion is failing because the Number_of_Times_Viewed__c equals 0. What is the optimal way to fix this?
Answer: A
NEW QUESTION # 125
Employee_c is a Child object of Company_c. The Company_c object has an external Id field Company_Id_c.
How can a developer insert an Employee_c record linked to Company_c with a Company_Id_c of '999'?
Employee_c emp = new Employee_c(Name='Developer'); emp.Company_r = '999'
Answer: D
NEW QUESTION # 126
A developer is writing code that requires making callouts to an external web service. Which scenario necessitates that the callout be made in an asynchronous method?
Answer: A
Explanation:
In Salesforce, a callout cannot be made directly from an Apex trigger (Option C). This is a fundamental architectural restriction of the platform. Triggers execute as part of a database transaction. If a trigger were allowed to make a synchronous callout, the database transaction-along with all its associated row locks- would remain open while waiting for a response from the external system. This could lead to severe performance bottlenecks and transaction timeouts.
To perform a callout based on a trigger event, the developer must move the callout logic into an asynchronous context, such as a @future(callout=true) method, a Queueable class, or by publishing a Platform Event.
Option A is incorrect because while asynchronous methods allow for higher CPU time, they do not extend the maximum individual callout timeout (120 seconds). Option B is incorrect because REST is simply a protocol and does not dictate synchronicity. Option D is incorrect because the limit for callouts in a single transaction is 100, so 10 callouts would still be permissible in a synchronous context (assuming they aren't in a trigger).
Consequently, the presence of a trigger is the only factor listed that programmatically mandates an asynchronous approach.
