Nutanix NCS-Core Practice Questions

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

A. foundation_VM-version-disk-0.geow2

B. foundation_VM-version. tar

C. foundation_VM-version. vmdk

D. foundation-version.tar.gz

B. foundation_VM-version. tar

C. foundation_VM-version. vmdk

Where in the Support Portal can it be determined if a version of AOS is supported on a particular hardware platform.

A. Solution Documentation

B. Upgrade Paths

C. Hardware Compatibility Lists

D. Compatibility and Interoperability Matrix

Explanation: To determine if a version of Acropolis Operating System (AOS) is supported on a specific hardware platform, the "Compatibility and Interoperability Matrix" section of the Nutanix Support Portal should be consulted. This resource provides detailed information on supported hardware for different AOS versions, ensuring that all components are compatible and supported for optimal operation.

A consultant has been tasked with increasing security on a Nutanix cluster by disabling password authentication when accessing the CVM and AHV hosts and instead moving to key-based SSH. What is the easiest way for the consultant to meet these requirements?

A. Enable STlGs via command line on SSH to a CVM.

B. Configure LDAP authentication through a secure server.

C. Enable Cluster Lockdown and provide an RSA key.

D. Restrict access with User Management in Prism.

C. Enable Cluster Lockdown and provide an RSA key.

Explanation:
The most straightforward approach for increasing security by disabling password authentication and moving to key-based SSH on a Nutanix cluster involves:
C. Enable Cluster Lockdown and provide an RSA key: Cluster Lockdown mode restricts management access to the cluster, ensuring that only key-based SSH authentication is used to access the CVM and AHV hosts, enhancing security by eliminating the use of passwords.

A consultant is working with a customer on a new cluster deployment.
While reviewing the customer questionnaire, the consultant notices that the customer has documented their DNS servers as follows:

CompanyDNSI 192.168.5.10
CompanyDNS2 192.1685.20

What should the consultant consider regarding this deployment?

A. Everything has been accounted for to ensure a successful deployment.

B. Internal Nutanix networking will interfere with the installation's ability to complete.

C. During deployment, the CVMs should be configured to use a separate network.

D. New IP's provided should be verified to not conflict with the customers network.

Explanation:
Noticing a potential typo or error in the DNS server IP address notation:
D. New IPs provided should be verified to not conflict with the customer's network: It's crucial to verify the accuracy and validity of the IP addresses provided, ensuring there are no typos and that the IPs do not conflict with existing network configurations. The noted IP '192.1685.20' appears to be incorrectly formatted and should be corrected and validated.

During Foundation, all nodes are imaged successfully. The cluster creation step fails. The consultant troubleshoots the issue and verifies that all Hosts and CVMs are up and running and responding to network pings. Which method should the consultant select to create the cluster?

A. Log into one of the hosts and run the cluster create command.

B. Image the Bare Metal nodes.

C. Log into one of the CVMs and run the cluster create command.

D. Factory reset the nodes and re-start the Foundation process.

C. Log into one of the CVMs and run the cluster create command.

Explanation: After confirming that all nodes (Hosts and CVMs) are operational and network accessible, the next step in troubleshooting a failed cluster creation process is to use one of the CVMs to manually initiate the cluster creation. This is done using the command cluster create from a CVM, which allows you to establish the cluster management and data services provided by Nutanix. This approach is recommended when the Foundation process has successfully imaged the nodes but the automatic cluster creation has failed.

During which part of the Knowledge Transfer does the customer learn about Nutanix basics and their environment at a high level?
