Nutanix Nutanix Certified Advanced Professional (NCAP) NCM-5.15 Questions & Answers

• Question 31:

  An organizations Nutanix Cluster is based on VMware vSphere. The cluster is configured to download software updates automatically. The administration needs to verify and eventually upgrade VMware hypervisor via Prism Ul. After logging

  in to Prism, the administrator receives the message shown:

  No available versions for upgrade.

  What is causing the current state?

  A. VMware support has expired, so downloads are not available.

  B. vSphere binaries need to be manually uploaded.

  C. The environment is running the latest vSphere version, so no update is required.

  D. The cluster is unable to connect to release api.nutanix-ccm:8D.

  Correct Answer: C

• Question 32:

  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

  Switch information on Nutanix AHV

  Managing and troubleshooting virtual guests' network connectivity issues is quite difficult, if you do not have right information about upstream switches. It is crucial to understand how Nutanix hosts are connected, hosting switch name,

  location, switch port number. Nutanix AHV leverages OVS (Open VSwitch) to manage AHV hosts and Guest OS network connectivity. OVS can use LLDP (Link Layer Discovery Protocol) to pull information from physical switches. LLDP is

  automatically enabled on Nutanix AHV. To have LLDP discovery working you have to enable it on the network port switches as well. Nutanix AHV will automatically pull switch information and present it in the Prism.

  In Prism Element, on main dashboard click on Home -> Network

• Question 33:

  An administrator is concerned that Prism will be inaccessible if Active Directory is unable to process logins. Which method should the administrator use to access the cluster in the event of this type of outage?

  A. Manage the cluster by using the "nutanix" user on the Prism leader CVM

  B. Create and use an emergency local account on the cluster

  C. Deploy an Active Directory server locally on the cluster

  D. Manage the cluster remotely by downloading ncli to a remote workstation

  Correct Answer: B

• Question 34:

  A Nutanix cluster is deployed with the following configuration:

  Three four-node blocks (A, B, and C)

  All Flash Redundancy Factor 2

  What is the effect of simultaneous disk failures on two nodes located in block A?

  A. VMs are migrated of the nodes with disk failures.

  B. Each node with a failed disk is marked as degraded.

  C. VM read and write operations continue normally.

  D. VMs on the nodes with failed disks are unable to write data

  Correct Answer: C

  Dual Disks Failures:

  With Replication Factor = 2, we have two copies of each data block. Also, with a 4TB Disk which is only 1TB utilized, we will have 1TB worth of blocks/data across the cluster (shorter rebuild times as we factor in the capacity utilized) ?plus

  with AOS proactive disk alerting, so, unless two disks are pulled at the same time, this can be a very rare occurrence of two drives failing at the same time.

• Question 35:

  An administrator receives an error indicating that the CVMs in the cluster are not syncing to any NTP servers. An investigation of the issue finds: The NTP servers are configured in Prism The time on all CVMs is the same Both the CVMs and AHV hosts are configured for the UTC time zone

  Which two steps can be taken to troubleshoot this issue? (Choose two.)

  A. Confirm that the NTP servers are reachable from the CVMs.

  B. Restart genesis on all CVMs.

  C. On a CVM. run the command a Hash ntpq -pn.

  D. Restart the chronos service on all CVMs.

  Correct Answer: AC

• Question 36:

  An administrator needs to make sure an RF3 cluster can survive a failure of two complete racks without negatively affecting performance. The current cluster configuration consists of the following: 30 All Flash Nodes: distributed 10 nodes per rack across three 42U racks Each node is configured with 20TB usable storage all flash (Cluster Total 600TB Usable) Current cluster utilization is 500TB storage Storage containers have Erasure Coding enabled

  Which configuration changes should be made to make sure the cluster meets the requirements?

  A. Expand the cluster to 50 nodes distributed evenly across 5 racks

  B. Expand the cluster to 48 nodes distributed evenly across 6 racks

  C. Expand the cluster to 60 nodes distributed evenly across 6 racks

  D. Expand the cluster to 40 nodes distributed evenly across 5 racks

  Correct Answer: C

• Question 37:

  An administrator needs to evaluate if the existing configuration of Protection Domains meets the specified corporate recovery policy for SQL Data. The corporate policy requires that all SQL Servers be recoverable at the DR site within 30 minutes, and must result in a maximum of 60 minutes of data loss. SQL data must be required.

  The protection domain is configured as follows: Application consistent snapshots are enabled The SQL server VMs are assigned to the Protection Domain as their own Consistency Group The Protection Domain schedule is configured as snapshots taken every 90 minutes from 7 am until 8 pm

  What must be changed to meet the required policy?

  A. Revise the schedule to be 15 minutes

  B. Revise the schedule to be 60 minutes

  C. Revise the schedule to be 30 minutes

  D. Revise the schedule to be 45 minutes

  Correct Answer: B

• Question 38:

  An administrator needs to relocate an AHV cluster to a new datacenter during a maintenance window. The cluster will use the same IPs in the new datacenter.

  Which two steps should be taken to prepare for this task? (Choose two.)

  A. Stop all Nutanix Files clusters

  B. Relocate the linked LDAP servers

  C. Shut down all user VMs in the cluster

  D. Reconfigure IPMI for the new datacenter

  Correct Answer: AC

• Question 39:

  For several days, an administrator notices the following alerts: CVM NIC Speed Low Warning Alerts Warning Alerts of CVM NIC not performing at optimal speed CVM is disconnected from the network Critical Alert Network Visualization page shows excessive dropped packets on CVM/Host.

  Which steps should be taken to determine which problem should be addressed first?

  A. Access the Hardware Page to verify resources are available Analyze all CVM Speed Alerts in the Alerts/Events page Analyze output for the network and interface properties and connectivity issues

  B. Verify Host/CVM connectivity on the Network Visualization page Use to verify the bridge and bond configuration Review alerts/events page for the CVM disconnected error

  C. Review Alerts page for NIC speed alerts and alert timing Analyze the genesis.out log file for process failures Assess the NIC properties in the Network Visualization > Host Properties page

  D. Restart networking services on the CVM Determine the current configuration of the affected CVM via output Access the Alerts/Events page for the CVM network connection failures

  Correct Answer: B
