Two MAG4610s are running in an active/passive cluster configuration. The system administrator is planning to apply a service package to the cluster.
Which process should the administrator follow?
A.
Perform the upgrade on the active node of the cluster. When completed, the node reboots and then pushes the service package to the passive node automatically.
B.
Perform the upgrade on the passive node of the cluster. When completed, the node reboots and then pushes the service package to the active node automatically.
C.
On the clustering status page, disable the active node. Perform the upgrade on the disabled node. When completed and the node reboots, enable the node on the clustering status page.
Repeat the process on the passive node.
D.
On the clustering status page, disable the passive node. Perform the upgrade on the disabled node. When completed and the node reboots, enable the node on the clustering status page.
Repeat the process on the active node.
I see A & B as valid answers, according to the administration manual:
Upgrading Clustered Nodes
You can easily upgrade every node in a cluster using the IC Series device by installing a newer service package on one node. After the installation is completed and the node reboots, the node pushes the service package to all nodes in the cluster.
Upgrading the Cluster Service Package
Install a newer service package on one cluster node only. When the installation process completes and the cluster node reboots, it instructs the other nodes to upgrade.
