What is the purpose of enabling Maintenance Mode on a PowerFlex node?

Question

Options

• APerform software upgrades
• BProtect volumes using snapshots
• CAdd new nodes to the cluster
• DIsolate the node for maintenance without impacting data availability

• D

Explanation

Enabling Maintenance Mode on a PowerFlex node isolates it from active I/O operations so that physical or administrative work can be performed on it - without disrupting data availability, since the system redistributes workloads and ensures data remains accessible through redundancy. Option A is wrong because software upgrades are handled through the upgrade workflow, not Maintenance Mode specifically. Option B is incorrect because snapshot-based volume protection is a separate data protection feature unrelated to node isolation. Option C is also wrong because adding nodes is an expansion operation performed through the cluster management interface, not Maintenance Mode.

Memory tip: Think of Maintenance Mode like a "Do Not Disturb" sign for a node - it tells the cluster "hands off this node's active duties" so you can safely work on it without the cluster panicking or losing data.
