NCM-MCI Online Practice Questions and Answers

An administrator is deploying several new application VMs to a Nutanix cluster. The application is very transactional with a 28/72 random, read/write ratio. What should the administrator do?

A. Add a minimum of four SSDs to each node to ensure all writes go to the SSDs.

B. Add a minimum of four virtual disks to each VM, and aggregate them on guest OS level.

C. Add one large SSD to each node and enable Flash Mode for the VMs.

D. Add one large virtual disk to each VM. and use it for all application data.

An administrator is implementing a VDI solution. The workload will be a series of persistent desktops in a dedicated storage container within a four-node cluster. Storage optimizations should be set on the dedicated storage container to give optimal performance including during a node failure event.

Which storage optimizations should the administrator set to meet the requirements?

A. Compression, Deduplication, and Erasure Coding

B. Deduplication and Erasure Coding

C. Compression and Deduplication

D. Compression only

An administrator needs to create and start five new VMs for a Data Analytics Project (OLAP). The VM Profile is as follows:

1.

vCPU:4

2.

vRAM: 64 GB

3.

vDisk: 1.5 TB

Each of the four nodes of the Nutanix cluster has the following:

1.

24 vCPU. 20% overall usage

2.

192 GB RAM, 60% overall usage

3.

2xl920GBSSD

4.

4x 2 TB HDD

At cluster level, there is a single RF2 container that is 30% utilized and has an extent store capacity of 13.5 TB.

Which component requires administrator attention?

A. Physical RAM, because it is not enough to power on all of the new VMs.

B. Physical Cores, because they are not enough to power on all of the new VMs.

C. Storage, because the capacity is not enough to create VMs.

D. Flash Tier because it is not enough to accommodate the workloads.

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 reIease-api.nutanix-ccm:8D.

An administrator is updating disk firmware using LCM and receives the following message:

"there have been 10 or more cluster services restarts within 15 minutes in the Controller VM"

The message appears as each drive is upgraded.

What is the reason this message is being generated?

A. A node has been rebalanced

B. A drive has been reformatted

C. A node has been rebooted

D. A drive has been ejected

A customer has a four-node cluster and is using Volume Groups to provide storage services to a SQL cluster. In the event of a CVM failure in the cluster, what is the expected IO path of the volume group's iSCSI targets?

A. vDisk directed at failure CVM are redirected to Data Services IP until CVM is reconnected

B. vDisk directed to CVM that failed to disconnect and will not reconnect without manual intervention

C. vDisk directed to failed CVM are redirected to another CVM and automatically reconnect

D. vDisk directed at failed CVM will disconnect and reconnect when the failed CVM comes back online

A customer has two mission-critical applications and needs to have them backed up to a remote location. The remote location is connected using a leased line and has an average latency of 7 ms. Which Nutanix technology will provide the shortest RPO possible?

A. NearSync

B. Leap

C. Metro Availability

D. AsynandDR

An administrator has an existing Nutanix seven-node cluster running at RF2 that must be changed to have the following capabilities:

1.

RF3 set for the cluster

2.

Performance tier deduplication

What is the minimum memory needed on the CVMs to allow for these capabilities?

A. 24GB

B. 28GB

C. 32GB

D. 20G?

A customer recently set up Async Replication between Site A and Site B. The customer wants to conduct a planned failover and clicks Activate on Site B.

The customer then runs the following command on Site A:

ncli pd deactivate_and__destroy_vms name=

What does this do to the customer environment?

A. VMs get deleted from Site B. and the protection domain is now Active.

B. VMs are powered off on Site A and must be manually powered on at Site B.

C. VMs get deleted from Site A and the protection domain is no longer active.

D. Customer must then manually power off VMs at Site A and power them on at Site B.

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:

1.

Network connectivity checks

2.

Network performance status

3.

Storage performance status

Which tool should be used to perform this test?

A. X-Ray

B. clurator_cli

C. NCC

D. diagnostic, py
