Question #: 86
Topic #: 8

A Cisco Secure Email Gateway administrator must provide outbound email authenticity and configures a DKIM signing profile to handle this task. What is the next step to allow this organization to use DKIM for their outbound email?

AEnable the DKIM service checker

BExport the DNS TXT record to provide to the DNS registrar

CImport the DNS record of the service provider into the Cisco Secure Email Gateway.

DConfigure the Trusted Sender Group message authenticity policy.

Show Suggested Answer

Suggested Answer: C

A TXT record is a type of DNS record that contains arbitrary text data that can be used for various purposes such as verification, configuration, or authentication. A TXT record can contain the DKIM public key per RFC 6376, which is used to verify the digital signature of an email message generated by the DKIM private key of the sender domain.

The other options are not valid because:

A) A CNAME record is a type of DNS record that maps an alias name to a canonical name or another alias name. It does not contain any DKIM public key information.

B) An AAAA record is a type of DNS record that maps a hostname to an IPv6 address. It does not contain any DKIM public key information.

D) A PTR record is a type of DNS record that maps an IP address to a hostname, which is the reverse of an A or AAAA record. It does not contain any DKIM public key information.

Alright, time to get our DKIM on! I'm feeling lucky, let's go with Option C and see what happens. What's the worst that could happen? Oh wait, don't answer that.

Option A is just too easy. Enabling the DKIM service checker? Pfft, that's like the first step. I'm going with the more advanced option B.

Option D? Really? Configuring the Trusted Sender Group message authenticity policy has nothing to do with DKIM setup. Come on, let's stay focused here!

I think Option C is also a valid answer. Importing the DNS record of the service provider into the Cisco Secure Email Gateway seems like a logical step.

Option B is the correct answer. Exporting the DNS TXT record and providing it to the DNS registrar is the next step to allow the organization to use DKIM for their outbound email.
