Nutanix Nutanix Certifications NCM-MCI Questions & Answers

• Question 101:

  An administrator protected a DB VM running on a Nutanix cluster with NearSync Replication, which schedules to repeat every 15 minutes to a second site. The daily change rate is low. During nightly backups, the replication window is missed due to write volume.

  Which two options describe the expected behavior? (Choose two.)

  A. NearSync stops working and fails over to the remote site.

  B. Protection Domain transitions back to the hourly schedule.

  C. The Administrator needs to re-enable it manually.

  D. The system continuously tries to get to the NearSync schedule.

  Correct Answer: AD

• Question 102:

  An administrator receives a notification that storage in a Nutanix cluster is unavailable. The cluster consists of five nodes and is configured with a Fault-Tolerance level of 1 (FT-1). Upon investigation, the administrator finds the following:

  1.

  All AHV hosts are powered on and the CVMs are running

  2.

  Nodes A, B, and C are connected to one top of rack switch

  3.

  Nodes D and E are connected to a second top of rack switch

  4.

  The cluster status command run on Node A shows that CVM services on nodes D and E are down Which issue is causing the storage outage?

  A. The default gateway for the CVMs and AHV hosts is down.

  B. The switch connecting Nodes D and E is down.

  C. The genesis process is down on both Nodes D and E.

  D. Nodes D and E are in maintenance mode.

  Correct Answer: C

• Question 103:

  Refer to the exhibit.

  

  A Nutanix host is connected as shown in the exhibit with br0-up set to active/backup. Physical Switch 1 experiences a power outage causing br0-up to failover to using eth2. The CVM and host become inaccessible. User VMs restart on other hosts in the cluster, which causes a disruption to those VMs.

  Which configuration issue likely caused this outage?

  A. Bridge br0-up should be configured to use balance-tcp rather than active/backup.

  B. The CVM should have eth1 connected to the OVS.

  C. The upstream port for eth2 is missing a VLAN.

  D. The user VMs only have one NIC

  Correct Answer: C

• Question 104:

  An alert about RX errors on eth2 on a node is reported in the cluster. The administrator logs in to the CVM in question, checks the ping_* files in the data/logs/syststats folder, and notices intermittent ping loss. The node in question has the following network configuration:

  

  Which action should be used to troubleshoot without disrupting the VMs running on this node?

  A. Replace the cable from eth2 to the switch

  B. Remove eth3 from br0-up and monitor for new alerts

  C. Check the port on the switch side for any errors

  D. Enable balance-s1b on br0-up and monitor if a problem persists

  Correct Answer: D

• Question 105:

  An administrator is monitoring the Nutanix v5.15-based AOS cluster performance logs and notices that a SQL server VM is greatly exceeding its intended maximum IOPS. The administrator has confirmed that a QoS policy was previously created for the group of VMs this server is a member of.

  What are two reasons that this VM would exceed its maximum configured IOPS from the QoS Policy? (Choose two.)

  A. The VM is missing the required snapshot needed to implement the QoS Policy.

  B. The VM was not created as an AFS virtual machine.

  C. The SQL Server VM has volume groups attached.

  D. It was cloned from another SQL Server VM that was a member of the QoS Policy.

  Correct Answer: BC
