Dell EMC Specialist – Implementation Engineer, ECS — Question 29

You are performing a troubleshooting steps on a 4 node VxRail cluster. The cluster uses Erasure Coding for all VMs. When you attempt to put a node into maintenance mode using the recommended vSAN data migration policy, the operation fails.
What could be done to successfully put the node into maintenance mode?

Answer options

• A. Use the 'No Data Migration' option
• B. Storage vMotion the VMs off the node
• C. Cold migrate the VMs off the node
• D. Use the 'Full Data Migration' option

Correct answer: D

Explanation

The correct answer is D, as using 'Full Data Migration' ensures that all data is moved off the node, allowing it to enter maintenance mode without issues. Options A and C may not adequately prepare the node for maintenance, and while option B could work, it may not be as effective as utilizing the full data migration method.
