Polls and Out of Office are two ways that CK can use Chatter to gather feedback and understand availability. Polls allow users to create surveys and collect opinions from other users. Out of Office lets users set a status message and an end date to inform others when they are away or busy. Streams and Topics are not related to the problem.


Question No. 3

The VP of Sales at Universal Containers has asked the app builder to let sales reps create opportunity records directly from the account, with a number of fields pre-populated.

Which feature should the app builder use to allow users to create the opportunity?

Show Answer Hide Answer
Correct Answer: A

The feature that the app builder should use to allow users to create the opportunity is a quick action. A quick action is a type of custom button or link that can create or update records, log calls, send emails, or launch flows from a record page or a global menu. The app builder can create a quick action on the account object that creates an opportunity record with pre-populated fields. Option B is incorrect because a default action is not a valid term, but rather a standard action that appears on every record page by default, such as Edit or Delete. Option C is incorrect because a custom button is not suitable for this requirement, as custom buttons can only display a URL or execute JavaScript when clicked. Option D is incorrect because a custom link is not suitable for this requirement, as custom links can only display a URL or execute JavaScript when clicked.


Question No. 4

Show Answer Hide Answer
Correct Answer: B

Validating an inbound change set does not affect any data or metadata in the target org.

Show Answer Hide Answer
Correct Answer: C

To ensure that opportunities are submitted into the approval process when their close date is pushed more than 30 days, an app builder should use an automated process to submit the record for approval. An automated process can be created using tools such as Process Builder or Flow Builder, and it can define the criteria and actions for submitting a record for approval. [Source]
