Nutanix Nutanix Certifications NCM-MCI-5.15 Questions & Answers

• Question 71:

  An administrator is deploying an application using Nutanix Volumes. After configuring the volume group and connecting the guest's iSCSI initiator to the volume group, they begin performance testing. The administrator learns that performance on the virtual disk attached to the iSCSI initiator is far less than that of a virtual disk connected directly to the VM.

  Which situation is causing this condition?

  A. The VM's iSCSI traffic is being routed to the data services IP subnet

  B. The performance test is generating small block random 10.

  C. The duster data services IP address is a bottleneck, shared with other iSCSI traffic

  D. Data Locality ensures that VM attached disks are always faster than iSCSI volumes.

  Correct Answer: C

• Question 72:

  A new Nutanix cluster is ready for production on a remote site with no IT staff. Changes to the infrastructure will cost money and probably cause a cluster stop. The administrator needs to perform a health check on the environment that should include:

  Network connectivity checks Network performance status Storage performance status

  Which tool should be used to perform this test?

  A. X-Ray

  B. clurator_cli

  C. NCC

  D. diagnostic, py

  Correct Answer: C

• Question 73:

  An administrator is notified that a bare metal database server is down. This database server is being served storage using a Nutanix Volume Group. Upon investigating, the administrator finds that the disks in the database server that map to the vDisks in the volume group have gone offline.

  What is causing this issue?

  A. The Volume Group Load Balancer has been disabled.

  B. Port 9443 is blocked in the server firewall.

  C. Port 3260 has been blocked in the server firewall.

  D. A CVM serving the Volume Group has gone offline.

  Correct Answer: D

• Question 74:

  An administrator is using Nutanix Move to migrate a Windows VM from ESXi to AHV. Automated guest preparation is failing with an error:

  The administrator is using the local built-in administrator account for the Windows VM Admin approval mode must remain enabled.

  What should the administrator do to continue with the migration with Nutanix Move?

  A. Use a Domain Admin account for the Windows VM

  B. Reboot the Windows VM and try the migration again

  C. Follow manual VM preparation guidelines

• Question 75:

  Microsegmentation was recently enabled in a Nutanix environment. The administrator wants to leverage Prism Central to create a policy that will block all traffic, regardless of direction, between two groups of VMs identified by their category. Which policy should be used to meet this requirement?

  A. A Quarantine Policy

  B. An Isolation Environment Policy

  C. An Application Security Policy

  D. A Whitehst-Based Policy

  Correct Answer: B

• Question 76:

  

  An organization is running a Nutanix Cluster based on AOS 5.10.x and VMware vSphere 6.7. Currently, the CVM network is segmented and Storage only nodes not present. A new security project based on NSX is coming. VMware Distributed Virtual Switches are required. The administrator needs to prepare the environment for the new project. Which step should the administrator use to initiate the project?

  A. Enable Nutanix Flow at the Prism Central Level

  B. Manually disable CVM network Segmentation

  C. Convert storage only nodes into vSphere nodes

  D. Enable Jumbo Frames to accommodate network frames

  Correct Answer: D

• Question 77:

  An administrator recently added VLAN 205 CRM in Prism Element. The workloads attached to the associated NICs are unable to establish network connectivity. Which Layer 2 protocol allows the administrator to troubleshoot this issue from Prism Element?

  A. HDLC

  B. SUP

  C. LACP

  D. LLDP

  Correct Answer: D

  After the migration, some SQL queries take longer to execute than prior to migration. The following SQL best practices were applied while creating the SQL VM on Nutanix: vDisks per SQL server VM

  Database and Log files on separate vDisk TempDB database drives and 1 TempDB log drive What should the administrator to do improve the SQL Server performance?

  A. Redistribute existing data by creating additional database file and enable autogrowth

  B. Create multiple TempDB data files and enable autogrowth

  C. Create multiple SQL log files and disable autogrowth

  D. Redistribute existing data by creating additional database files and disable autogrowth

• Question 78:

  A. Use multiple subnets for iSCSI traffic

  B. Enable RSS (Receive Side Scaling)

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

  D. Distribute workload across multiple virtual disks

  Correct Answer: BD

• Question 79:

  

  An administrator responsible for a VDI environment needs to investigate reports of slow logins. The administrator finds that increasing the number of vCPUs from 2 to 4 will reduce the login times. Production workloads are consuming 75% of the host CPU on the cluster. The administrator increases the vCPU count on all of the VDI VMs.

  What are two impacts on the cluster? (Choose two.)

  A. Increase CPU utilization%

  B. Increase CPU ready%

  C. Increase memory utilization%

  D. Increasing CPU counts will decrease memory utilization

  Correct Answer: AB

  A. As a single VM on the Nutanix cluster

  B. On hardware external to the Nutanix duster

  C. As a clustered VM setup on the Nutanix cluster

  D. As a single VM deployed on the host that contains the Prism leader CVM

  Correct Answer: B
