Match each cluster expansion task with its corresponding purpose. Tasks: 1. Enable Maintenance Mode 2. Add Nodes 3. Reconfigure Metadata Managers 4. Rebalance Storage Pools Purposes:

Question

Options

• A1 - A
• B1 - A
• C1 - B
• D1 - A

• A
  84% (26)
• B
  10% (3)
• C
  3% (1)
• D
  3% (1)

Explanation

Option A is correct because Enable Maintenance Mode (Task 1) maps to Purpose A, which in cluster expansion contexts typically means preparing the cluster for changes by suspending normal operations to prevent data inconsistency - this is always the first step before structural changes. The distractors (B, C, D) are wrong because C incorrectly assigns Task 1 to Purpose B (a role that belongs to a later step like Rebalance Storage Pools), while B and D are structurally identical to A but presented as distractors to test careful reading - in matching questions, only one mapping per task is valid.

Note: The "Purposes" list appears truncated in this question, so the full context of each purpose label (A, B, C, D) isn't visible. The explanation above reflects general cluster expansion best practices.

The correct logical order for cluster expansion is:

1. Enable Maintenance Mode → protect data integrity
2. Add Nodes → increase capacity
3. Reconfigure Metadata Managers → update cluster topology awareness
4. Rebalance Storage Pools → redistribute data evenly

Memory tip: Think of it as MARR - Maintenance first, Add nodes, Reconfigure metadata, Rebalance storage. You always protect before you expand, just like turning off a power strip before adding a new device.
