A network engineer must configure a Cisco ESA to prompt users to enter two forms of information before gaining access. The Cisco ESA must also join a cluster machine using preshared keys. What must be configured to meet these requirements?
A.
Enable two-factor authentication through a RADIUS server and then join the cluster by using the Cisco ESA GUI.
B.
Enable two-factor authentication through a TACACS+ server and then join the cluster by using the Cisco ESA CLI.
C.
Enable two-factor authentication through a TACACS+ server and then join the cluster by using the Cisco ESA GUI.
D.
Enable two-factor authentication through a RADIUS server and then join the cluster by using the Cisco ESA CLI.
I think D is the answer.

Cluster configuration options must be done via the CLI on the ESA and cannot be created or joined in the GUI.
Note: If you run the PREPJOIN option, you need to commit your changes to the primary ESA before you run clusterconfig on the secondary ESA and join that appliance to your newly configured cluster. This is noted from the output throughout the operation: to join this appliance to a cluster with pre-shared keys, log in to the cluster machine, run the clusterconfig > prepjoin > new command , enter the next details, and commit your changes.
So I believe it is D
Answer is D. See: https://www.cisco.com/c/en/us/support/docs/security/email-security-appliance/200885-ESA-Cluster-Requirements-and-Setup.html under "Requirements" section.
"You cannot create or join a cluster from the Graphical User Interface (GUI). You must use the Command Line Interface (CLI) to create, join, or configure clusters of machines. Once you have created a cluster, you can change configuration settings from either the GUI or the CLI.
...
Although you cannot create or join clusters or administer cluster specific settings from the GUI (the equivalent of the clusterconfig command), you can browse machines in the cluster, create, delete, copy, and move settings among the cluster, groups, and machines (that is, perform the equivalent of the clustermode and clusterset commands) from within the GUI."
