VMware 2V0-33.22 Exam - Topic 6 Question 55 Discussion

Actual exam question for VMware's 2V0-33.22 exam

Question #: 55
Topic #: 6

A cloud administrator is responsible for managing a VMware Cloud solution and would like to ensure that I/O-intensive workloads run in the most optimum way possible.

Which two steps should the administrator complete on I/O-intensive workloads to meet this requirement? (Choose two.)

AEnsure that the VMware hardware version is 7 or later.

BEnable the memory hot-add feature.

CConfigure the LSI Logic Parallel SCSI controller.

DConfigure the VMware Paravirtual SCSI (PVSCSI) adapter.

EConfigure a maximum of two CPU cores per socket.

Show Suggested Answer

Suggested Answer: A, D

The two steps that the cloud administrator should complete on I/O-intensive workloads to ensure the best performance possible are to configure the VMware Paravirtual SCSI (PVSCSI) adapter and to ensure that the VMware hardware version is 7 or later. The PVSCSI adapter provides improved performance and scalability compared to the LSI Logic Parallel SCSI controller. Additionally, the hardware version should be 7 or later to ensure that the virtual machine is able to take advantage of the latest features and enhancements. Enabling the memory hot-add feature and configuring a maximum of two CPU cores per socket will not improve the performance of I/O-intensive workloads.

VMware Cloud on AWS also includes a paravirtualized SCSI storage adapter, PVSCSI (also called VMware Paravirtual). The PVSCSI adapter offers a significant reduction in CPU utilization as well as potentially increased throughput compared to the default virtual storage adapters, and is thus the best choice for environments with very I/O-intensive guest applications. In order to use PVSCSI, virtual machine must be using virtual hardware version 7 .or later https://docs.vmware.com/en/VMware-Cloud-on-AWS/services/vmc-aws-performance.pdf

I’m a bit confused about the hardware version requirement. Does it really impact I/O performance, or is it just a compatibility thing?

I practiced a similar question where configuring the PVSCSI adapter was mentioned as a best practice for I/O-intensive workloads. That feels right.

I think enabling the memory hot-add feature is more about memory management than I/O performance, so I’m leaning towards the SCSI adapter options.

I remember something about optimizing I/O with specific SCSI controllers, but I'm not sure if it's PVSCSI or the LSI Logic one.

Hmm, I'm a little confused by this question. I know I need to optimize I/O performance, but I'm not sure which specific steps are the most important. I'll need to review my notes and try to remember the best practices for this type of scenario.

This question is a bit tricky, but I think I've got a good strategy. I'll start by ensuring the VMware hardware version is up-to-date, as that can impact I/O performance. Then I'll focus on configuring the PVSCSI adapter, as that's a key component for I/O-intensive workloads. I'm feeling pretty good about this.

Okay, let's see here. I remember from my studies that the PVSCSI adapter is important for improving I/O performance, so that's definitely one of the steps I'll choose. As for the other, I'm not entirely sure, but I'll try to reason it out based on my knowledge.

This is easy, D and D! The PVSCSI adapter is the way to go, and you can never have too many PVSCSI adapters. It's like the more PVSCSI, the better the I/O, right? (*laughs*)

Hmm, I'm going with D and E. The PVSCSI adapter is a no-brainer, and limiting the CPU cores per socket can help optimize I/O performance. Who needs memory hot-add when you have cores, am I right?
