Nutanix NCP-US Exam - Topic 4 Question 13 Discussion

Actual exam question for Nutanix's NCP-US exam

Question #: 13
Topic #: 4

An administrator has been experiencing performance issues with a SQL VM. To address these issues, the administrator migrated the database to a Volume Group. Following the migration, the performance issues have continued.

What should the administrator do to resolve these performance issues?

Ause multiple vDisks in the Volume Group.

BEnable Jumbo Frames.

CDisable CHAP,

DUse multiple subnets for iSCSI traffic.

Show Suggested Answer

Suggested Answer: A

According to Nutanix Volumes - Recommendations And Best Practices1, ''Multiple disks per Nutanix node may also improve an application's performance. For performance-intensive environments, we recommend using between four and eight disks per CVM for a given workload.'' Therefore, the administrator should use multiple vDisks in the Volume Group to distribute the SQL workload across more disks and nodes.

Not sure if Jumbo Frames will really fix it, though.

I practiced a similar question about iSCSI traffic, and using multiple subnets seemed to help with performance in that scenario.

Disabling CHAP seems risky; I feel like it could expose the system to security issues. I’m not confident that’s the right move.

I think enabling Jumbo Frames might improve network performance, but I can't recall if it directly affects SQL VM performance.

I remember reading that using multiple vDisks can help with performance, but I'm not entirely sure if that's the best option here.

I'm feeling pretty confident about this one. I think the best solution is to use multiple vDisks in the Volume Group to distribute the workload.

Using multiple subnets for iSCSI traffic might be worth exploring, as that could help isolate and optimize the network traffic.

I'm a bit confused on this one. Enabling Jumbo Frames or disabling CHAP don't seem directly related to the performance issues described.

I think the actual number of risers is important for stairs, but I'm not completely sure if that's what they mean by type parameters.

If the users cannot see the IP addresses, I feel like it could involve permissions. Option B related to updating the UNIX ID seems possible, but I'm not confident.
