A clustered controller must contain spare resources (such as networking ports) to accommodate a
failover.
A.
True
B.
False
Explanation:
Network device, datalink, and interface failures do not cause the clustering
subsystem to
consider a head to have failed. To protect against network failures â whether inside or
outside the appliance â IPMP and/or LACP should be used instead. These network
configuration options, along with a broader network-wide plan for redundancy, are orthogonal
to clustering and are additional components of a comprehensive approach to availability
improvement.
