Answer 37

B. Queueable Apex can take non-primitive types: Such as sObjects or custom Apex types.
C. Monitoring: When you submit your job by invoking the System.enqueueJob method, the method returns the ID of the AsyncApexJob record.
D. Chaining jobs: You can chain one job to another job by starting a second job from a running job.

Question 38

True/False: Because queueable methods are functionally equivalent to future methods, most of the time you’ll probably want to use queueable instead of future methods.

Answer 38

True

- This is not the case when your functionality is sometimes executed synchronously, and sometimes asynchronously.

Question 39

A. You can add only one job from an executing job, which means that only one child job can exist for each parent job.
B. The execution of a queued job counts once against the shared limit for asynchronous Apex method executions.
C. You can add up to 50 jobs to the queue with System.enqueueJob in a single transaction.

Question 41

What is false for Scheduled Apex?
Choose 1 answers.
A. The Apex Scheduler lets you delay execution so that you can run Apex classes at a specified time. This is ideal for daily or weekly maintenance tasks using Batch Apex.
B. The class implements the Schedulable interface and must implement the only method that this interface contains, which is the schedule method.
C. To invoke Apex classes to run at specific times, first implement the Schedulable interface for the class. Then, schedule an instance of the class to run at a specific time using the System.schedule method.
D. The parameter of this method is a SchedulableContext object. After a class has been scheduled, a CronTrigger object is created that represents the scheduled job. It provides a getTriggerId method that returns the ID of a CronTriggerAPI object.

Answer 41

B. The class implements the Schedulable interface and must implement the only method that this interface contains, which is the schedule method.

• The method is called execute.

Question 42

C. Use extreme care if you’re planning to schedule a class from a trigger. You must be able to guarantee that the trigger won’t add more scheduled jobs than the limit.
D. Synchronous Web service callouts are not supported from scheduled Apex. To be able to make callouts, make an asynchronous callout by placing the callout in a method annotated with @future(callout=true) and call this method from scheduled Apex. However, if your scheduled Apex executes a batch job, callouts are supported from the batch class.

Answer 44

A. You can only have 100 scheduled Apex jobs at one time and there are maximum number of scheduled.
C. Use extreme care if you’re planning to schedule a class from a trigger. You must be able to guarantee that the trigger won’t add more scheduled jobs than the limit.
D. Synchronous Web service callouts are not supported from scheduled Apex. To be able to make callouts, make an asynchronous callout by placing the callout in a method annotated with @future(callout=true) and call this method from scheduled Apex. However, if your scheduled Apex executes a batch job, callouts are supported from the batch class.

Question 45

What is False for the Flex Queue?
A. Future Jobs can be seen in the Flex Queue like any other async job.

C. A request can contain headers that provide more information about the request, such as the content type.
D. We should only use REST Apex when SOAP Apex is impossible.

Answer 46

A. REST Callouts consists of a HTTP method (Like GET) a URI (the endpoint address) and other optional properties.
B. When the server processes the request, it sends a status code in the response (Like 200 for success)
C. A request can contain headers that provide more information about the request, such as the content type.

Question 47

True/False: Apex test methods don’t support callouts, and tests that perform callouts fail, instead you have to mock the callout.

Answer 47

True.
- A Callout Mock can be created as both a Static Resource that is then called by the test class or as a test class that implements the HttpCalloutMock interface.

Question 48

True/False: WSDL2Apex automatically generates Apex classes from a WSDL document. You download the web service’s WSDL file, and then you upload the WSDL and WSDL2Apex generates the Apex classes for you. The Apex classes construct the SOAP XML, transmit the data, and parse the response XML into Apex objects

Answer 48

True.

Question 49

True/False: As you know; to deploy or package Apex code, at least 75% of that code must have test coverage. This coverage does not include classes generated by WSDL2Apex.

Answer 49

False.

Question 50

True/False: When you create an Apex class from a WSDL, the methods in the autogenerated class call WebServiceCallout.invoke, which performs the callout to the external service. When testing these methods, you can instruct the Apex runtime to generate a fake response whenever WebServiceCallout.invoke is called by implementing the WebServiceMock interface and specify a fake response for the testing runtime to send.

Answer 50

True.
- Instruct the Apex runtime to send this fake response by calling Test.setMock in your test method. For the first argument, pass WebServiceMock.class. For the second argument, pass a new instance of your WebServiceMockinterface implementation.

5. @HttpPatch
To its definition:
A. Typically used to update fields in existing records.

Answer 52

1. @HttpGet - B. Reads or retrieves records.
2. @HttpPost - C. Creates records.
3. @HttpDelete - D. Deletes records.
4. @HttpPut - E. Typically used to update existing records or create records
5. @HttpPatch - A. Typically used to update fields in existing records.

• You can use each annotation only once in each Apex class.

Question 53
