An organization owns a fully functional multi-controller Aruba network with a Virtual Mobility Master (VMM) in VLAN 20. They have asked a network consultant to deploy a redundant MM on a different server. The solution must offer the lowest convergence time and require no human interaction in case of failure.
The servers host other virtual machines and are connected to different switches that implement ACLs to protect them. The organization grants the network consultant access to the servers only, and appoints a network administrator to assist with the deployment.
What must the network administrator do so the network consultant can successfully deploy the solution? (Select three.)
A. Reserve one IP address for the second MM and another IP address for its gateway
B. Configure an ACL entry that permits IP protocol 50, UDP port 500, and multicast IP 224.0.0.18.
C. Allocate VLAN 20 to the second server, and extend it throughout the switches.
D. Reserve one IP address for the second MM and another for the VIP.
E. Configure an ACL entry that permits UDP 500, UDP 4500, and multicast IP 224.0.0.1.
F. Allocate another VLAN to the second server, and permit routing between them.
