Nutanix Certified Master – Multicloud Infrastructure (NCM-MCI) — Question 22

An administrator is notified that a bare metal database server is down. This database server is being served storage using a Nutanix Volume Group. Upon investigating, the administrator finds that the disks in the database server that map to the vDisks in the volume group have gone offline.
What is causing this issue?

Answer options

• A. The Volume Group Load Balancer has been disabled.
• B. Port 9443 is blocked in the server firewall.
• C. Port 3260 has been blocked in the server firewall.
• D. A CVM serving the Volume Group has gone offline.

Correct answer: C

Explanation

The correct answer is C because port 3260 is used for iSCSI connections, which are necessary for the database server to access the vDisks in the Nutanix Volume Group. If this port is blocked, the server cannot communicate with the storage. Options A, B, and D do not address the specific communication issue related to the vDisks, making them incorrect.
