What is the primary purpose of placing a PowerFlex node into maintenance mode?

To temporarily isolate the node for planned activities without disrupting cluster operations

To increase the node's performance during high-demand periods

To automatically update the node's firmware without user intervention

To permanently remove the node from the cluster

After exiting maintenance mode, what should you verify to ensure the cluster has returned to normal operation?

That the node is online and all storage pools are in a healthy state

That the node has been removed from the cluster

That the node's IP address has changed

That all data has been migrated off the node

After exiting maintenance mode on an SDS node, the administrator notices that the node is in a 'Degraded' state. What is the most likely cause and the appropriate action?

The node's maintenance mode flag was not cleared; re-enter and exit maintenance mode.

The node's IP address has changed; reconfigure the network settings.

The node is still rebuilding data; wait for the rebuild to complete and verify the node returns to 'Normal'.

The node has a hardware failure; replace the node immediately.

How does maintenance mode affect cluster performance?

Performance is unaffected because maintenance mode is transparent to the cluster

Performance is always reduced to a fixed percentage of normal capacity

Performance may be reduced because the remaining nodes handle additional I/O load

Performance is always improved because the node is not processing I/O

What is the impact of placing a node into maintenance mode on data availability?

Data availability is reduced to read-only access

Data becomes unavailable until the node exits maintenance mode

Data availability is maintained because the cluster continues to serve I/O from other nodes

Data availability is unaffected because maintenance mode does not change cluster behavior
