Exam HPE6-A45 topic 1 question 16 discussion

Actual exam question from HP's HPE6-A45

Question #: 16
Topic #: 1

An AOS-Switch needs to be configured to support tunneled node in role-based mode. The Mobility Controller administrators tell the switch administrators that the
AOS-Switch will integrate with a cluster of Mobility Controllers. The cluster virtual IP address is 10.1.1.10.
How should switch administrator integrate the AOS-Switch with the cluster?

A. Double-check the settings with the Mobility Controller administrators because the planned configuration is incomplete with the switch settings.
B. Configure the virtual IP address as the tunneled-node-server address, tunneled node will work, but the clustering features will not provide redundancy.
C. Configure the virtual IP address as the tunneled-node-server address. The switch will automatically learn controller IP addresses to which to tunnel various traffic.
D. Configure the virtual IP address for the primary tunneled-node-server and an actual controller IP address for the backup tunneled-node-server in order to receive redundancy.

Answer is C: "You only need to set a single tunnel node server IP. Use the VIP for the cluster. When the switch contacts the VIP, it will in turn, receive assignments with the actual IP address of the MC's in the cluster.

the answer is C. Cluster enables load balancing and failover capabilities beyond the VRRP mechanisms. The switch receives Ip addresses and create a tunnel to A-ASC and to S-ASC so redundancy is done.

When the switch uses role-based tunneled-node, it can tunnel traffic to clustered MCs. These MCs typically also use VRRP, although not always. However, the cluster enables load balancing and failover capabilities beyond the VRRP mechanisms. With this method, again, you only need to set a single tunnel node server (controller) IP address on the AOS-Switch. Use the virtual IP address for the cluster. When the switch contacts this IP address, it receives assignments with the actual IP addresses of two MCs. One is the switch’s active Switch Anchor Controller (A-SAC), and the other is the switch’s standby SAC (S-SAC). The switch establishes tunnels with both controllers.
