Answer

Setup > Deployment > Logs

Answer

Setup > Security > Audit Trail

Answer

Setup > Custom Code > Apex Settings

Question 5

A developer is writing a test class that requires several custom objects to be populated with data. What is the most efficient way to handle this across multiple test methods?

Accepted Answer

Use the @TestSetup annotation. The @TestSetup annotation allows creating data once for all test methods within a class, reducing execution time.

Answer

Create a static method and call it at the start of every test method

Answer

Insert the data inside the constructor of the test class

Answer

Use the Test.loadData() method for all objects

Question 6

What is the primary purpose of the 'System.debug()' statement?

Accepted Answer

To write information to the debug log. System.debug() writes information to the debug log to help developers diagnose execution flow and variable states.

Answer

To display an error to the end user

Answer

To stop the execution of the code

Answer

To log an audit trail of configuration changes

Question 7

Which of the following is a limitation of Change Sets?

Accepted Answer

They can only be used between related orgs. Change Sets are strictly one-way and cannot be used to deploy changes from production back to a sandbox.

Answer

They cannot deploy Custom Objects

Answer

They are limited to 100 components

Answer

They require the CLI to be installed

Question 8

What must be true for a developer to deploy Apex code to a production environment?

Accepted Answer

All tests must pass and coverage must be at least 75%. The code must have at least 75% coverage and all tests must pass.

Answer

The code must have 100% test coverage

Answer

Tests do not need to be run if the code was tested in sandbox

Answer

Only the new classes require coverage

Question 9

When testing asynchronous Apex, how do you ensure that the scheduled job has finished before asserting results?

Accepted Answer

Use Test.stopTest(). Test.stopTest() forces any asynchronous processes, such as @future or Schedulables, to execute before the code execution continues.

Answer

Query the AsyncApexJob object

Answer

Use System.runAs()

Answer

Use Thread.sleep()

Question 10

When using the Metadata API to deploy components, which XML file must be present to define the components included in the package?

Answer

manifest.xml

Answer

deploy.xml

Answer

components.xml

Question 11

Answer

Test classes can only use data created within the same method

Question 14

A developer is using 'Test.isRunningTest()' in their production code. Why is this generally considered a poor practice?

Accepted Answer

It creates different code execution paths between test and production. While sometimes necessary, relying on it can lead to code paths that are not tested in production exactly as they execute in tests.

Answer

It causes the test to fail

Answer

It causes excessive governor limit usage

Answer

It is not supported in production

Question 15
