Nutanix Updated NCP-MCI-6.10 Exam Questions and Answers by rafi

Before performing any LCM (Life Cycle Manager) updates on a Nutanix cluster, it is essential to ensure that the AOS (Acropolis Operating System) is updated to the required or recommended version. AOS updates provide foundational enhancements, security patches, and compatibility improvements, which are critical for the successful execution of LCM updates.

From theNutanix Enterprise Cloud Administration (ECA)course materials:

“LCM updates depend on the underlying AOS version. Before proceeding with any hardware or software updates through LCM, administrators must ensure that the cluster is running a supported AOS version. This step ensures compatibility and prevents issues that can arise from dependencies between AOS and the update components.”

Additionally:

“AOS upgrades should be performed first to bring the cluster to a version that supports the desired LCM updates for components like BIOS, firmware, and hypervisors. This aligns the management stack with the latest features and security enhancements.”

Therefore, updating AOS before performing LCM updates is a mandatory prerequisite to ensure stability and supportability for the entire cluster lifecycle management process.

Scale-out Prism Central deployments consist of multiple nodes running the Prism Central service. Nutanix documentation emphasizes that:

“When deploying multi-node Prism Central, an FQDN backed by DNS can provide request distribution across all Prism Central nodes, enabling load balancing and increased concurrency.”

A Virtual IP in contrast only directs traffic to a single active Prism Central node. Internal behavior notes:

“A VIP is not active-active; it designates one node as primary for all inbound requests.”

“Using an FQDN with DNS round-robin or an external load balancer allows the cluster to distribute workload across all PC nodes.”

The FQDN allows:

distributing API/UI traffic across multiple Prism Central nodes

improving performance under heavy load

enabling parallel query handling

avoiding bottlenecks on the primary node

SSL certificates apply to either VIP or FQDN. Segmentation and resiliency are unrelated to FQDN usage.

Thus, the correct answer is Load Balancing.

Metro Availability requires that VMs always read data from their primary site to maintain optimal performance and prevent remote data access latency.

Option C (Migrate the VM to its primary site and set appropriate rules) is correct:

If a VMfails over to the secondary sitebut is still running in the primary site, it will read data remotely, causinghigh latency and performance issues.

The solution is tomigrate the VM back to the primary siteand configureDRS rulesorhost affinity settingsto prevent unwanted movement.

Option A is incorrect:

The command listsactive Metro Availability protection domainsbut doesnot resolvethe issue.

Option B is incorrect:

Must-affinity rules can help, but they should be configuredafter migrating the VM back to the primary site.

Option D is incorrect:

RunningNCC health checkswill onlydiagnose the issue, not resolve it.
