Nutanix Nutanix Certifications NCP-MCI-6.5 Questions & Answers

• Question 1:

  An administrator needs to deploy an application with a large amount of data connected via Nutanix volumes.

  Which two actions should the administrator take when designing the Volume Group? (Choose two.)

  A. Distribute workload across multiple virtual disks

  B. Enable RSS (Receive Side Scaling)

  C. Use multiple subnets for iSCSI traffic

  D. Enable thick provisioning on the Volume Group(s)

  Correct Answer: AB

• Question 2:

  What is the minimum time a newly created Deduplication storage policy takes to apply to the VMs in the container?

  A. 5 Minutes

  B. 10 minutes

  C. 30 minutes

  D. 60 minutes

  Correct Answer: C

• Question 3:

  An administrator needs to configure Prism to send encrypted messages to a set of recipients.

  Which setting must be applied?

  A. Use SMTP Port 25

  B. Configure Prism Central to use Cluster Lockdown

  C. Install SSL certificates on Prism Central

  D. Set SMTP Security Mode to STARTTLS

  Correct Answer: D

  Explanation: The best way for the administrator to configure Prism to send encrypted messages to a set of recipients is to set the SMTP Security Mode to STARTTLS. This will ensure that all messages sent over SMTP are encrypted and secure. Additionally, the administrator should consider installing SSL certificates on Prism Central to ensure that the messages are being sent securely. Finally, the administrator should consider configuring Prism Central to use Cluster Lockdown, which will help ensure that the messages are only sent to the intended recipients.

• Question 4:

  A user is complaining about slowness of a mission-critical MSSQL Server. The administrator logs into Prism Element to investigate the VM performance and observes what is shown in the diagram.

  

  Which action would best improve VM performance?

  A. Disable hyperthreading in the BIOS.

  B. Add additional RAM to the user VM.

  C. Add additional RAM to the host on which the VM is running.

  D. Ensure the host's CPUs ere not excessively overcommitted.

  Correct Answer: B

  Explanation: Prism Element is a graphical user interface that allows you to manage Nutanix clusters1. You can use Prism Element charts to understand Nutanix cluster workloads and troubleshoot performance related issues2. memory

  optimized virtual machine sizes offer the best performance for SQL Server workloads on Azure VMs. Adding more RAM to the user VM can help reduce paging and improve query execution times.

  SQL Server performance can be affected by disk latency and throughput. By creating separate virtual disks for data and logs, you can spread activity across multiple spindles and reduce disk contention.

• Question 5:

  An administrator receives complaints of poor performance in a particular VM.

  Based on the VM performance metric, what is the most likely cause of this behavior?

  A. Oplog is full cannot serve IO request from this VM.

  B. The host's CPU is severely overloaded.

  C. SSD tier is not big enough to serve workloads' IOPS demand.

  D. The VM needs more vCPUs

  Correct Answer: C

  Explanation: one of the key metrics to consider for VM performance is IOPS (Input/Output Operations Per Second), which is a measure of the number of input/output requests a device processes per second3. Another metric is throughput, which is a measure of how much data a device transfers per second3.

• Question 6:

  A two-node ROBO cluster is configured with a witness VM.

  

  What happens when Node A goes down?

  A. The- cluster becomes unavailable and goes into read-only mode.

  B. All operations and services on the Node B are shut down and go into a waiting state.

  C. The cluster is unaffected and no administrator intervention is required.

  D. Node B sends a leadership request to the Witness VM and goes into single-node mode.

  Correct Answer: D

• Question 7:

  Which command should an administrator run from the CLI to view the uplink state of all AHV nodes in the cluster?

  A. allssh show_uplinks

  B. manage_ovs show_uplinks

  C. allssh manage_ovs show_uplinks

  D. manage ovs show uplinks

  Correct Answer: C

• Question 8:

  An administrator is setting up a Nutanix cluster and needs to configure the default VLAN. Which configuration should the administrator choose?

  A. Vlan.0

  B. Vlan.1

  C. Vlan.2

  D. Vlan.7

  Correct Answer: B

  Explanation: Nutanix cluster is a group of Nutanix nodes that share data and resources across a network1. A VLAN is a virtual LAN that allows devices on different physical LANs to communicate as if they were on the same network2. by

  default, a virtual NIC (VM NIC) on a guest VM operates in access mode and can send and receive traffic only over its own specified VLAN. The default VLAN ID for access mode interfaces is 1.

  Therefore, by choosing Vlan.1 as the default VLAN, you can simplify the network configuration and avoid potential issues with other VLAN IDs.

• Question 9:

  Upon logging into Prism Central, an administrator notices high cluster latency. How can the administrator analyze data with the least number of steps or actions?

  A. Modify Data Density in the main Prism Central dashboard.

  B. Click on the chart in the widget to expand the data elements.

  C. Take note of the duster name and create a new Analysis chart.

  D. Click the cluster name in the cluster quick access widget.

  Correct Answer: B

• Question 10:

  An Administrator has been asked to deploy VMs using a specific image. The image has been configured with settings and applications that will be used by engineering to develop a new product by the company.

  The image is not available on the desired cluster, but it is available in other cluster associated with Prism Central.

  Why isno't the image available?

  A. The image bandwidth policy has prevented the image upload.

  B. The cluster should be removed from all categories.

  C. The cluster has not been added to the correct category

  D. The image placement policy was configured with enforcement.

  Correct Answer: D

  Explanation: When a placement policy is enforced, images are only allowed to be deployed on clusters that are part of categories that are associated with the policy. If the desired cluster is not associated with the policy, then the image will not be available for deployment. https://next.nutanix.com/how-it-works-22/image-management-for-ahv-clusters-and-dealing- with-the-inactive-image-37300
