Explanation:

https://www.cisco.com/c/en/us/products/security/what-is-dmarc.html

SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) are two email authentication mechanisms that are utilized during this process. SPF and DKIM allow the domain owner to publish DNS records that specify the authorized IP addresses or hosts for sending emails from that domain and sign the messages with a cryptographic key to prove their authenticity and integrity.

DMARC (Domain-based Message Authentication, Reporting and Conformance) is an email authentication standard that builds on SPF and DKIM and allows the domain owner to publish DNS records that specify how receivers should handle messages that fail SPF or DKIM verification, such as reject, quarantine, or none, and how to report back the results of DMARC validation.

The other options are not valid email authentication mechanisms that are utilized during this process, because they are not part of DMARC standard.

Answer: B

Explanation:

According to the [Cisco Secure Email User Guide], you can create a text resource of type Disclaimer Template and use the code view option to insert HTML code into the text box. Then, you can use this text resource in a content filter to prepend or append the HTML message to the email body[1, p. 15-16].

The other options are not valid because:

A) Creating a text resource type of Disclaimer Template and pasting the HTML code into the text box without changing to code view will not work, as the HTML code will be treated as plain text and not rendered properly[1, p. 15].

C) Creating a text resource type of Notification Template and pasting the HTML code into the text box will not work, as Notification Templates are used for sending notifications to senders or recipients, not for modifying the email body[1, p. 17].

D) Creating a text resource type of Notification Template and changing to code view to paste the HTML code into the text box will not work, as Notification Templates are used for sending notifications to senders or recipients, not for modifying the email body[1, p. 17].

Answer: B

Explanation:

The maximum message size that can be configured for encryption on the Cisco ESA is 25 MB. This is the default value for the Maximum Message Size for Encryption setting in the Encryption Profile. Messages that exceed this size will not be encrypted and will be delivered as normal.

Answer: C

Explanation:

To encrypt SMTP with TLS on a Cisco Secure Email Gateway appliance when the sender requires TLS verification, the components that are required are an X.509 certificate and matching private key from a CA. The certificate must be signed by a trusted CA and contain the domain name or IP address of the listener in the Subject or Subject Alternative Name fields. The private key must be unencrypted and match the certificate.Reference: [Cisco Secure Email Gateway Administrator Guide - Configuring TLS]
