Nutanix NCS-Core Practice Questions

A customer recently bought services from their consultant to re-configure an existing Cluster for a new use case. The data on the cluster is not important. The customer does not know the CVM usernames and passwords. Which Foundation tool should the consultant use to resolve this issue?

A. Foundation VM - Auto Discovery

B. Foundation Applet(CVM) - Auto Discovery

C. Foundation VM - Bare Metal

D. Foundation Applet(CVM) - Bare Metal

C. Foundation VM - Bare Metal

Explanation:
For re-configuring an existing cluster for a new use case where data preservation is not a concern, and there is a lack of CVM credentials:
C. Foundation VM - Bare Metal: This tool allows for a complete re-installation of the Nutanix software from scratch, which is ideal in scenarios where existing configurations and data are no longer needed, and access credentials are unknown or lost.

An administrator needs to install prism central for their 2550 multi-cluster environment.
How should they deploy the application?

A. Deploy a large 3-VM Prism Central instance

B. Deploy a large 1-VM Prism Central instance.

C. Deploy a small 3-VM Prism Central instance.

D. Deploy a small 1-VM Prism Central instance.

A. Deploy a large 3-VM Prism Central instance

A consultant is working to setup the network before starting the Foundation process. How should the consultant complete this task?

A. Using the shared IPMI port, ensure that the connected switch can auto-negotiate to 1 Gbps.

B. Disable IPv6 on the network to which the nodes are connected to ensure that IPv6 unicast is blocked.

C. Ensure the IPMI of the nodes are reachable using pre-configured IPMI IPv6 addresses.

D. On Nutanix NX Series, connect the IPMI port and any one of the data ports to the switch.

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?

A. The ISL between switches is not configured.

B. SNMP is not configured properly.

C. br0 and br1 are not defined.

D. The cluster is using RDMA-enabled NICs.

B. SNMP is not configured properly.

A consultant creates three storage containers (container-1, container-2, container-3). The customer requires that only container-1, which will be utilized as an NFS datastore, be presented to external hosts. However, users are able to mount all three containers. What is causing this problem?

A. Compression was turned on for all containers.

B. A Container-level whitelist entry was configured.

C. Deduplication was turned on for all containers.

D. A Global whitelist entry was configured.

How should a consultant verify that a Nutanix cluster can tolerate a single-node failure?

A. [root@cvm~]# ncli cluster get-domain-fault-tolerance-status type=node

B. nutanix@cvm~$ ncli cluster get-domain-fault-tolerance-status type=node

C. [root@avh~]# ncli cluster fault-tolerance-status type=node

D. nutanix@cvm~$ ncli cluster status type=node

B. nutanix@cvm~$ ncli cluster get-domain-fault-tolerance-status type=node

Explanation: To verify that a Nutanix cluster can tolerate a single-node failure, the consultant should use the command nutanix@cvm~$ ncli cluster get-domain-fault-tolerance-status type=node. This command is executed from the Controller Virtual Machine (CVM) and checks the cluster's fault tolerance status specifically for node failures, providing insights into how the cluster's data resiliency and redundancy configurations are holding up against potential single-node failures.
