VMware Certified Professional - Data Center Virtualization (VCP-DCV) Practice Exam

What should an administrator ensure if there is a 'busy' status while trying to delete an NFS datastore?

1. Verify the NFS heartbeat settings.

2. Check for connected virtual machines on the datastore.

3. Attempt to delete it without deleting VMs first.

4. Ensure the datastore is not connected to any storage clusters.

The correct answer is: Check for connected virtual machines on the datastore.

The correct choice highlights the importance of checking for connected virtual machines on the NFS datastore before attempting to delete it. When an NFS datastore is marked as 'busy,' it is often because there are active virtual machines using that datastore for their files. If a virtual machine is connected and operational, the datastore cannot be removed until those connections are terminated. This is due to the need to maintain data integrity and avoid disruption to running workloads. If an administrator attempts to delete the datastore while virtual machines are still connected, it will lead to issues and potential data loss, hence the status will continue to show as 'busy.' Therefore, ensuring that all virtual machines are powered off and disconnected from the datastore is a critical first step in successfully removing it. This choice is particularly vital compared to others, which either focus on unrelated settings or imply removal actions without first ensuring that the datastore is free of dependencies. For instance, verifying NFS heartbeat settings ensures availability but does not directly address the 'busy' status. Similarly, attempting to delete the datastore without prior checks can create complications if it is indeed in use. Lastly, while ensuring the datastore is not connected to storage clusters might have relevance in some contexts, it does not address the immediate issue of connected virtual machines causing
