Question 61

Refer to the exhibit.

An administrator is adding a new node to a cluster. The node has been imaged ta the same versions of AHV and AOS that the cluster is running, configured with appropriate IP addresses, and br0-up has been configured in the same manner as the existing uplink bonds.

When attempting to add the node to the cluster with the Expand Cluster function in Prism, the cluster is unable to find the new node.

Based on the above output from the new node, what is most likely the cause of this issue?

    Correct Answer: A

    The most likely cause of the issue is that the existing cluster and the expansion node are on different VLANs. When adding a new node to a cluster, it is crucial that all nodes are on the same VLAN in order to communicate properly. If they are on different VLANs, the cluster cannot discover the new node. The provided exhibit shows correctly configured LACP settings, so the upstream switch ports are likely not the problem.

Discussion
Blitz1Option: A

A is the correct answer because: B - bond is up and lacp is active as per image so LACP was configure on the switch C - is total non-sense D - might be BUT hard to believe there is a firewall on the same subnet... A- remain the only one which makes sense because the fallowing must be true when you add new host: "Add host or CVM IPs to discover hosts within the same network." Those can be in the same network but if there on diff vlan it will not work

I believe i was wrong with this done. A is still valid but also B and because there is a picture related to B maybe the correct answer should be B. From my point of view this question might be incomplete. Br0-up is the name of the bond and not the status of the bond.(like interface up ... or like you configure in a switch a port-channel and if it's not up there is a issue with it) To check the status of the bond we should use " ovs-appctl bond/show br0-up " and if lacp_status: negotiated is present than we have a succesful lacp conf in both party. https://portal.nutanix.com/page/documents/kbs/details?targetId=kA0320000004H0vCAE
