NCM-MCI-5.15 Nutanix Certified Master - Multicloud Infrastructure (NCM-MCI) 5.15 Questions and Answers

An administrator is planning to deploy a Nutanix cluster to support a few high-performance VMs. This deployment will have the following considerations:

• Individual VMs will likely generate network throughputs in the range of 90-100Mbps

• Due to the configuration of the VMs, it is unlikely that a node will host more than one or two of them at a time

• Individual VMs will communicate with only a few (one or two) remote hosts at a time

• Multicast will not be used in the environment

• The hosts are connected via two 1GbE network connections

How should the administrator configure the network bonds to meet this requirement while maintaining the simplest switch configuration?

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.)

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:

• All AHV hosts are powered on and the CVMs are running

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

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

• 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?

The node in question has the following network configuration:

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

An administrator is performing a set of routine checks and notes that Prism Central is running with 4 vCPUs and 21 GB RAM. The organizations environment is based on two Nutanix clusters with 170 VMs plus a Legacy vSphere infrastructure. No manual changes have been done on Prism Central VM.

Which configuration justifies the current Prism Central configuration?

An administrator has a 32-node hybrid cluster with CPU, RAM and storage utilization of 80%. A database VM is configured with VM Flash.

What is causing this IO latency?

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?

An administrator is deploying Nutanix Files 3.5 and needs to configure the sizing of the FSVMs for an increased number of concurrent SMB connections over the default 750.

What should the administrator do?

A company needs to replicate their VMs to a remote site and must have an RPO of less than 1 hour.

When creating a protection domain, what should an administrator do to meet this requirement?

An administrator needs to replace the self-signed certificate on a cluster. Which two requirements must be met as part of the process? (Choose two.)

An administrator needs to maximize storage potential in a six-node cluster. The container is configured with the following:

Post-process compression

Capacity deduplication

What should the administrator configure to increase space savings?

An administrator has two clusters: Site A and Site B.

Async DR is configured between the clusters as follows:

• Site A is the Primary Site

• Site B is the Secondary inactive Site, no VMs running

• Site A is fully in Production

• Site B used as Backup/Disaster Recovery

The customer wants to perform a planned failover between the sites.

How should the administrator accomplish this?

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.)

An administrator is migrating 5MB shares from a third-party platform to Nutanix Files with the following characteristics:

• Shares contain user profile directories

• DFS-N will be used

How should the administrator create target shares for this migration?

An administrator is deploying a three-tier application on a Nutanix Enterprise Cloud consisting of web, application, and database VMs. Traffic between the servers must be limited to specific services/ports. There is an application layer firewall VM deployed on one host in the cluster.

In which way should the administrator meet this requirement?

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

• vCPU:4

• vRAM: 64 GB

• vDisk: 1.5 TB

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

• 24 vCPU. 20% overall usage

• 192 GB RAM, 60% overall usage

• 2xl920GBSSD

• 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?

An administrator needs to migrate workloads from a Nutanix cluster running VMware ESXi to Nutanix AHV. The migration process needs to be completed in multiple VM groups and support roll back in case any problems are found during user acceptance testing.

Which action should the administrator perform?

An administrator wants to utilize Network Visualization to monitor the physical and logical network on the Nutanix cluster. The first-hop switch has LLDP enabled. The network switch information is still not being displayed.

What is causing this problem?

An administrator is responsible for the following Nutanix Enterprise Cloud environment:

• A central datacenter with a 20-node cluster with 1.5PB of storage

• Five remote sites each with a 4-node cluster with 200TB storage
