NCS-CORE Online Practice Questions and Answers

A customer wants to know the details of network validation testing. Where can the consultant find this information?

A. Handover checklist

B. Test plan

C. Operations Guides

D. As-Built Guide

A customer is deploying Nutanix AHV clusters over hundreds of remote sites worldwide. Prism Central will be used to centrally manage all clusters. Customer security policy requires the use of MS Active Directory (AD).groups to authenticate all network devices.

Which method should be consultant use to meet the requirements?

A. Integrate AD authentication on all CVMs.

B. Integrate AD authentication on Prism Central Only.

C. Proxy Prism Element traffic through Prism Central.

D. Integrate AD authentication on all Prism Element Clusters.

During a technical call with a customer, it is identified that this installation will be software only on Dell servers. The out-of-band management interfaces will not be given IP addresses until the consultant is onsite. Which Foundation method should be used for this type of installation?

A. Bare metal using iDRAC MAC addresses.

B. Bare metal using LAN MAC addresses.

C. Bare metal using block serial numbers.

D. Bare metal using node serial numbers.

An administrator is deploying a three-tier application on a Nutanix Enterprise Cloud consisting of web, application, and database VMs. Traffic between theservers 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?

A. Create a network for each type of VM, and use policy-based routing to control the traffic flow

B. Configure a security policy and service chain redirecting the server traffic through the firewall

C. Separate the web. application and database VMs on to dedicated VLANs

D. Categorize the VMs in Prism Central and utilize Flow to set a security policy

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?

A. Enable Async Replication with an RPO of 60 minutes

B. Enable Near-Sync Replication with an RPO of 15 minutes

C. Enable Entity Sync on the designated VMs

D. Enable Availability Zones and send the VM to multiple targets

A VM is exhibiting one or more of the following baseline values based on the past 30 days:

CPU usage<; 20%

CPU ready time<; 5%

Memory usage<; 50% (moderately) or<; 20% (severely)

Memory swap rate = 0 Kbps

Which type of VM is being described?

A. Constrained VM

B. Inactive VM

C. Bully VM

D. Over-Provisioned VM

A consultant deploys a four-node VMware ESXi cluster and vCenter server. An HA/DRS cluster is configured for all four nodes. The customer deploys five new VMs on the cluster.

During the knowledge Transfer, a network cable on one node is removed to demonstrate HA and migration of the VMs to another host. In the HA/DRS cluster settings, the VM Restart Priority for all CVMs is set to Disabled. The customer

observes warnings that the CVM on the ejected host is no longer powered on.

Which ESXi HA/DRS cluster setting is missing?

A. Enable EVC for the cluster.

B. Disable VM Monitoring on all CVMs.

C. Disable Automation Level on all CVMs.

D. Enable Host Monitoring.

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.

An administrator recently added in 3 nodes to an existing 5 node cluster. While 1 node came with its own block, theother 2 nodes where added to an existing share. After adding the nodes, the administrator sees that the hardware tab displays the correct number of nodes, but incorrect position in the diagram tab.

What should the administrator do to resolve the issue?

A. Check the factory_config.json for all 3 nodes

B. SSH into CVM and perform genesis restart on each CVM

C. SSH into the CVMs and run genesis acropolis stop; cluster start

D. Check the factory_config. json for the two single nodes.

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
