A user running a Computer Aided Design (CAD) application is complaining about slow response time within the VM, particular when moving windows or rendering images.

Which VM metric will guide the administrator toward diagnosing the problem?

  1. Storage Controller Latency
  2. GPU Usage
  3. Swap in Rate
  4. Hypervisor Memory Usage (%)

Answer(s): B

Explanation:

A GPU (graphics processing unit) is a specialized hardware device that can accelerate graphics rendering and computation for applications that use APIs such as DirectX, OpenGL, CUDA, and OpenCL. A GPU can also offload the CPU from encoding and decoding tasks for remote display protocols such as Frame Remote Desktop Protocol (FRP). A VM can use a GPU either by directly accessing a physical GPU (pGPU) on the host or by using a virtual GPU (vGPU) that shares a pGPU

with other VMs. A user running a computer aided design (CAD) application may benefit from using a GPU or a vGPU to improve the performance and responsiveness of the application, especially when moving windows or rendering images. However, if the GPU or vGPU is not properly configured or provisioned, the user may experience slow response time within the VM. Therefore, to diagnose the problem, the administrator should monitor the GPU Usage metric for the VM. The GPU Usage metric shows the percentage of GPU resources that are consumed by the VM over time3. The administrator can use Prism Central to view the GPU Usage metric for each VM in a chart or a widget4. The administrator can also use Prism Central to view other metrics related to GPU performance, such as GPU Memory Usage, GPU Encoder Usage, and GPU Decoder Usage3. By analyzing these metrics, the administrator can determine if the VM is using the GPU efficiently and optimally, or if it needs more or less GPU resources.

An administrator needs to ensure logs, alerts and information is consistent across clusters that are located in different countries.

Which service needs to be configured?

  1. SMTP
  2. DNS
  3. SNMP
  4. NTP

Answer(s): D

Explanation:

NTP service needs to be configured to ensure logs, alerts and information is consistent across clusters that are located in different countries. NTP stands for Network Time Protocol and it is used to synchronize the clocks of all the nodes in a cluster1. This helps to maintain accurate timestamps for logs, alerts and other information that are generated by Nutanix clusters1.



An administrator manages an AHV cluster that is dedicated to a dev/test environment. The administrator receiving complaints from users that they are unable to create new VMs on the cluster.

After the reviewing the cluster, the administrator finds that the memory resources are almost fully utilized, with many VMs over-provisioned on memory.

What option is the most efficient resolution to enable additional VMs to be created?

  1. Enable Memory Overcommit on the over-provisioned VMs.
  2. Enable Memory HA on the over-provisioned VMs.
  3. Upgrade the nodes with additional memory DlMMs.
  4. Disable HA Reservation on the cluster.

Answer(s): A

Explanation:

Enable Memory Overcommit on the over-provisioned VMs is the most efficient resolution to enable additional VMs to be created. Memory overcommit allows VMs to use more memory than physically available on a host by compressing and swapping memory pages to storage1. This can improve memory utilization and increase VM density on a cluster1. However, memory overcommit is not supported when HA is configured to use reserved hosts, so you may need to disable HA reservation on the cluster before enabling memory overcommit1.



Refer to Exhibit:



The Update Source for LCM has been configured as shown in the exhibit. Inventory is failing consistently.

What is the likely cause of this issue?

  1. Port 433 Is blocked by a firewall.
  2. Port 80 is blocked by a firewall.
  3. The administrator does not have a valid portal account.
  4. The license assigned to the cluster has expired.

Answer(s): A
