Nutanix NCS-Core - Nutanix Certified Services Core Infrastructure Professional (NCS-Core 6.8)
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?
A customer already has a Prism Central (PC) instance deployed in their environment and expects the consultant to unregister the old cluster before registering the new cluster
What steps should the consultant take to safely and successfully unregister the customer's former cluster from PC?
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?
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 relocate an AHV cluster to a new datacenter during a maintenance window. The cluster will use the same IPs in the new datacenter.
Which two steps should be taken to prepare for this task? (Choose two.)
Where in the Support Portal is the Best Practices guide for vSphere Networking located?
An administrator recently added in 3 nodes to an existing 5 node cluster. While 1 node came with its own block, the other 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?
In which part of the Knowledge Transfer can the customer learn how to create, escalate, comment, and close cases?
A new Nutanix cluster is ready for production on a remote site with no IT staff. Changes to the infrastructure will cost money and probably cause a cluster stop. The administrator needs to perform a health check on the environment that should include:
• Network connectivity checks
• Network performance status
• Storage performance status
Which tool should be used to perform this test?
A customer has HE servers with DiscoverOS and wants to install a Nutanix cluster.
Which method should a consultant use to meet the requirements?
