A. The EZONEXAM VLAN must be created.
B. The desired ports must be added to the new EZONEXAM VLAN.
C. The EZONEXAM VLAN must be added to all of the domains.
D. The EZONEXAM VLAN must be named.
E. An IP address must be configured for the EZONEXAM VLAN.
F. None of the above. VLAN creations are automatic.
A,B,D 解析：Explanation:
Creating a VLAN is done in 3 steps:
1. Create the VLAN
2. Name the VLAN
3. Assign ports to the VLAN
From there, other features and functionality can be configured, but these are the only steps that are required for the addition of a VLAN.
Incorrect Answers:
C. The VLAN needs only to be added to a single switch, where it can act as a stand-alone VLAN, or it can be transferred to other switches in the network through the use of the VTP protocol.
E. VLANs operate at layer 2, and although many are configured with a layer 3 IP address, it is not absolutely necessary to do this.
