REST uses .
Correct answer: D

Question #2
An org has a custom object, Registeration_c that has a lookup relationship to the Opportunity object. What should a developer use to create a stand-alone Vlsualforce page that displays the Registration c records related to an Opportunity.
Correct answer: D
Explanation
A standard controller on Opportunity lets the stand-alone page display the related Registration records without custom Apex, since the relationship is a lookup.

Question #4
Which use case can only be performed by using asynchronous Apex?
Correct answer: D
Explanation
A trigger cannot make a callout synchronously, so calling a web service from a trigger must be done with asynchronous Apex such as a Future method.

Question #5
A Visualforce page needs to make a callout to get biding information and tax information from two different REST endpoints. The information needs to be Displayed to the user at the same time and the return value of the billing information contains the input for the tax information callout. Each endpoint might take up to two minutes to process. How should a developer implement the callouts?
Correct answer: A
Explanation
Continuations keep the page under callout limits and let the tax callout follow the billing response, so both long-running callouts finish and display together.

Question #6
A developer is writing unit tests for the following method: Which assertion would be used in a negative test case?
Correct answer: C
Explanation
A negative test case passes input that must not match the expected result, so asserting null for an invalid input is correct. System.assertEquals(null, isFreezing('asdf')) checks the method rejects a non-freezing value.

Question #7
What Salesforce tool lets you deploy/retrieve metadata, check status of apex jobs, and check responses of REST calls?
Correct answer: C
Explanation
Workbench is the web tool that can deploy and retrieve metadata, monitor apex job status, and inspect REST API call responses. The Migration Tool only deploys metadata, while the Developer Console and Streaming API do not cover all three.

Question #8
An org has a requirement that addresses on Contacts and Accounts should be normalized to a company standard by Apex code any time that they are saved. What is the optimal way to implement this?
Correct answer: D
Explanation
Placing a trigger on both Account and Contact that delegates to one helper class keeps the normalization logic in a single place. Having one object's trigger call the other object's trigger is not valid practice in Apex.

Question #9
A developer is integrated with a legacy on-premises SQL database. What should the developer use to ensure the data being integrated is matched to the right records in Salesforce?
Correct answer: D
Explanation
A field marked as an External ID stores the legacy system's unique key and lets upsert match incoming rows to the right Salesforce records. Lookups, formulas and external objects cannot be used as the matching identifier for integration.

Question #10
A developer has written an After Update trigger on Account. A workflow rule and field update cause the trigger to repeatedly update the Account records. How should the developer handle the recursive trigger?
Correct answer: C
Explanation
A static Boolean flag set before the trigger performs its update stops the same trigger from running again in the same transaction. A global variable cannot be defined in Apex, and deactivating the workflow rule removes required business logic.
