Huawei H13-629 Exam - Topic 2 Question 75 Discussion

Actual exam question for Huawei's H13-629 exam

Question #: 75
Topic #: 2

A Huawei OceanStor 9000 is externally shared using NFS and CIFS at the moment.

You want to set some parameters to improve the performance of the NFS mounted under the Linux operating system. Which of the following description is correct?

ARsize / wsize, read and write the maximum size of each block, it is recommended to adjust to the maximum. General Linux operating system environment, the maximum value of 1M.

BAsync, allowing asynchronous data write, synchronous write requirements. NFS server must brush each data into the hard disk before it can return success delay higher.

CNoatime, if you do not need to record the file access time, you can increase this parameter to avoid frequent access, modify the access time to open pin.

DNolock, if there is a shared file between NFS clients, you can use this parameter. Reduce service-side file lock overhead.

D can definitely reduce overhead in shared environments.

Wait, I thought noatime was just for SSDs?

A is correct, max block size really helps performance.

I’m leaning towards option D with nolock. I remember it being useful for reducing overhead, but I’m not completely confident about its implications for file sharing.

I feel like I’ve seen noatime mentioned in practice questions before. It definitely helps with performance by reducing unnecessary writes, but I’m not clear on the exact benefits.

I think option B about async writes makes sense. I recall that synchronous writes can really slow things down since they wait for the disk to confirm.

I remember studying about NFS parameters, but I'm not entirely sure if the maximum block size really is 1M for Linux. It seems a bit high.

The nolock option in D is interesting, but I'm not sure I fully understand the implications of disabling file locking. Might be worth researching that one a bit more.

Option C about the noatime parameter sounds promising. Avoiding frequent access time updates could definitely boost performance without too much risk.

Hmm, I'm a bit confused about the async and sync write options. Does option B really mean we should disable synchronous writes? That seems risky to me.

I think option A is the correct answer. Adjusting the rsize and wsize to the maximum value of 1M for a Linux environment seems like a good way to improve NFS performance.
