Which two statements about Cisco ESA clusters are true? (Choose two.)
A. A cluster must contain exactly one group.
B. A cluster can contain multiple groups.
C. Clusters are implemented in a client/server relationship.
D. The cluster configuration must be managed by the cluster administrator.
E. The cluster configuration can be created and managed through either the GUI or the CLI.
DB is correct.
Under Requirements Portion:
Cluster configuration options must be done via the CLI on the ESA and cannot be created or joined in the GUI.

IMHO, should be BD.

You must use the CLI command clusterconfig to create, join, or configure clusters of appliances. Once you have created a cluster, you can manage non-cluster configuration settings from either the GUI or the CLI.
> clusterconfig
Do you want to join or create a cluster?
1. No, configure as standalone.
2. Create a new cluster.
3. Join an existing cluster over SSH.
4. Join an existing cluster over CCS.
Once the cluster is configured, you are presented the full clusterconfig menu:
> clusterconfig
This command is restricted to “cluster” mode. Would you like to switch to
“cluster” mode? [Y]>
Cluster [cluster_name]
Choose the operation you want to perform:
– ADDGROUP – Add a cluster group.
– SETGROUP – Set the group that machines are a member of.
– RENAMEGROUP – Rename a cluster group.
– DELETEGROUP – Remove a cluster group.
– REMOVEMACHINE – Remove a machine from the cluster.
– SETNAME – Set the cluster name.
– LIST – List the machines in the cluster.
– CONNSTATUS – Show the status of connections between machines in the cluster.
– COMMUNICATION – Configure how machines communicate within the cluster.
– DISCONNECT – Temporarily detach machines from the cluster.
– RECONNECT – Restore connections with machines that were previously detached.
– PREPJOIN – Prepare the addition of a new machine over CCS.
Correct seems to be BE
Within the cluster, machines (Cisco appliances) are divided into groups; every cluster will contain at least one group

I would say it`s BD. IMHO.

Regarding answer E, I think this answer is outdated as per:
