QUESTION: 17

What is the difference between using the Call and Branch methods in an activity step to invoke other activities?

Call provides more robust debugging capability than Branch, while Branch provides better run- time performance.
Branch overrides the security restrictions of the called activity allowing you to easily test code; it will not run in production.
Branch creates a new thread to allow asynchronous processing, while Call runs in the thread from it was invoked.
Call returns to the originating activity, while Branch skips the remainder of the originating activity.

Answer(s): D

Explanation:

The difference between using the Call and Branch methods in an activity step to invoke other activities is that Call will return to the originating activity once the called activity completes, while Branch will not return to the originating activity and will skip the remainder of it after the called activity completes.

QUESTION: 18

An application contains a flow action with an Apply to: class of TRB-HRApps-Work-Feedback in a locked ruleset.
When updating the application, you save the existing flow action into a new minor version of the ruleset this time applied to TRB'HRApps-Work so it can be used by more than one case type.
How do you prevent the application from using the rule in TRB-HRApps-Work-Feedback?

Save an additional new version of the flow action applied to TRB-HRApps-Work-Feedback and set the availability to "Blocked".
Save an additional new version of the flow action applied to TRB-HRApps-Work-Feedback and set the availability to "Withdrawn".
Save an additional new version of the flow action applied to TRB-HRApps-Work-Feedback and set the availability to "Not available".
Save an additional new version of the flow action applied to TRB-HRApps-Work and set the availability to "Final".

Answer(s): B

Explanation:

To prevent the application from using the rule in TRB-HRApps-Work-Feedback, you would save an additional new version of the flow action applied to TRB-HRApps-Work-Feedback and set the availability to "Withdrawn". This marks the rule as no longer valid for use in the application.

QUESTION: 19

A medium-size toymaker wants to fulfill orders received during the peak season in December and process the orders in batches multiple times a day.
How do you implement this use case?

Create one scheduled job and set its run schedule to multiple times a day.
Create scheduled jobs, one for each run, that can process accumulated orders.
Create batches of orders and send each batch for processing when it gets full.
Create a queue processor that can process orders received by the company.

Answer(s): D

Explanation:

To fulfill orders received during the peak season in December and process the orders in batches multiple times a day, you would create a queue processor that can process orders received by the company. Queue processors are designed to handle asynchronous, high-volume processing, which is suitable for the described use case.
