In the DMARC verification profile on the Cisco Secure Email Gateway appliance, which action must be set for messages that result in temporary failure to prevent these emails from being rejected?

No Action

Answers
D.

No Action

Suggested answer: A

Explanation:

Accept is the action that must be set for messages that result in temporary failure to prevent these emails from being rejected. Accept allows Cisco ESA to deliver the messages without applying any DMARC actions or modifications.

To configure the accept action for messages that result in temporary failure on Cisco ESA, the administrator can follow these steps:

Select Mail Policies > DMARC Verification Profile and click Edit Settings for the DMARC verification profile that applies to the messages.

Under DMARC Actions, select Accept from the drop-down menu for Messages That Result in Temporary Failure.

Click Submit.

The other options are not valid actions for messages that result in temporary failure to prevent these emails from being rejected, because they either apply DMARC actions or modifications or do nothing.
