NCS-Core Practice Questions

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?

After a consultant runs Foundation, the imaging process fails.

In which two locations can the consultant find the logs? (Choose two.)

A consultant is planning an installation and needs to collect configuration items to be used during the install. The data needed from the customer are IP addresses, Gateway, DNS servers, and NTP Servers.

Which Cluster Deployment document must be completed with the customer?

A customer has a mail server and needs Nutanix to send email notifications about errors that might occur in Prism. The following information is included under SMTP Server Settings

◦IP Address of mail server

◦Port Security Mode

◦From email address

What should the consultant set up before arriving onsite?

An administrator needs to initiate a new VDI project within a couple of months. Prism Central reports there are no storage resources to accommodate such workloads.

The administrator sees many powered-off VMs and has the authority to delete test VMs powered off at least for 30 days. Test VMs belong to the Test category.

Using Prism Central, which steps are required to identify the correct VMs to be deleted?

A consultant is completing final network failover testing on a recently deployed AHV cluster.

The cluster consists of the following:

•Three nodes

•Two uplinks connected to two switches

•Supported SFPs

The consultant removed one SFP+ out of each node. Two of the nodes (Hostl I Host2) failed over to the backup NIC correctly without any interruption but have lost communication with the third node (Host 3) hypervisor/CVM. Inserting the original SFP+ back into the problematic node allowed the network to be connected and the two healthy nodes could communicate successfully again.

What should the consultant validate first?

During a pre-engagement call, a customer explains that network cables are missing from the boxes. The consultant examines the bill of materials more closely to verify the quantity and type required by the hardware. The rack is already equipped with one OOBM Ethernet switch and two 10GbE SFP+ ToR switches.

Which cables should the consultant recommend to the customer for implementing in this scenario?

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.)

Which two files should be downloaded to deploy Foundation VM on VMware ESXI or AHV Hypervisors? (Choose two.)

An administrator learns that some security settings in a cluster have been changed. The environment is out of compliance with required policies.

Which function should be used to revert any settings that have changed from the defaults and prevent further violations?
