NCP-MCI-6.10 Exam Dumps - Nutanix NCM-MCI Questions and Answers

Nutanix requires thatall cluster components synchronize time using an external NTP (Network Time Protocol) server.

Option A (Adding an external NTP server) is correctbecause Nutanix best practices recommend using anexternal time source to prevent clock drift between cluster nodes.

Option B (DNS server IP) is incorrect: ADNS server does not provide NTP services.

Option C (Server with DNS hostname) is incorrectunless the DNS hostnameresolves to an NTP server.

Option D (IP of the Domain Controller) is incorrectbecausenot all domain controllers provide NTP servicesunless explicitly configured.

Receive Side Scaling (RSS) VirtIO-Net Multi-Queue improves network performance by distributing network processing across multiple CPU cores.

Option C (Enable RSS VirtIO-Net Multi-Queue) is correct:

This settingreduces CPU bottlenecksby allowing multiple queues to handle network packets.

It isessential for high-throughput network applications.

Option A (Add more vCPUs) is incorrect:

CPU resources are important, butwithout enabling RSS, additional vCPUs will not optimize network traffic distribution.

Option B (Enable AHV Turbo Technology) is incorrect:

AHV Turbo improvesdisk I/O, notnetwork I/O.

Option D (Add more RAM) is incorrect:

RAM does not directly impact network performance.

When using Metric or Entity Charts in Prism Central for performance monitoring, the most granular preset time interval that can be selected is1 hour.

From theNutanix Enterprise Cloud Administration (ECA)course materials:

“Prism Central provides performance data visualization with customizable time intervals. The smallest preset interval for metric and entity charts is 1 hour, providing highly detailed performance information over short periods.”

This allows administrators to monitor performance fluctuations at a fine-grained level, aligning with best practices for troubleshooting and optimization.

Port mirroring requires the source and target VMs to be on the same host to efficiently copy network traffic without additional routing overhead.

Option B (Source VM and Target VM are on the same host) is correct:

AHV’s port mirroringonly works within a single hostbecause network packets are intercepted before leaving the hypervisor.

If the VMs are on different hosts,mirroring cannot be configured without additional network tools.

Option A (Same VLAN) is incorrect:

VLAN membership isnot a requirementfor port mirroring.

Option C (Same subnet) is incorrect:

Port mirroring happens atthe virtual switch level, which does not require VMs to be in the same subnet.

Option D (Same VPC) is incorrect:

While VPCs provide network isolation,they do not control port mirroring availability.

Nutanix AHV networking supports multiple bond types that determine how traffic is distributed across physical NICs. The detailed guidance in the AHV networking section states:

“Active-Active bonding provides load distribution of outbound traffic across all interfaces in the bond, allowing aggregate throughput beyond a single physical adapter.”

Active-backup keeps only one NIC active at a time and provides no throughput gain. Active-Active with MAC pinning distributes VMs across NICs but does not aggregate the total throughput for a single VM and is typically used with switch-independent designs.

Because the requirement is to “take advantage of bandwidth beyond a single adapter,” only the standard Active-Active bond type satisfies this, as it truly aggregates available bandwidth.

Therefore, the correct bond type is Active-Active.

Nutanix documentation for Cross-Hypervisor Disaster Recovery (CH-DR) specifies that Nutanix Guest Tools (NGT) must be installed on all VMs participating in ESXi to AHV recovery workflows. NGT includes the VM Mobility Drivers, which are required for the VM to interpret AHV device models, storage controllers, and network adapters during recovery. The documentation notes that without NGT installed, VMs may fail to boot or attach devices correctly after being recovered on AHV. Legacy BIOS, RDMs, and delta disks are not listed as prerequisites or contributing factors for CH-DR success. Therefore, installing Nutanix Guest Tools on the source VM is mandatory for successful cross-hypervisor recovery.

The NCC alert indicates connectivity failure to the remote site. Resolving this involves confirming network connectivity and re-establishing the remote site configuration if necessary.

From theNutanix Enterprise Cloud Administration (ECA)course materials:

“The primary ports used for replication between clusters are 2009 (for Prism Element API) and 2020 (for data replication). Ensuring these ports are open and reachable is critical for remote site connectivity.”

Also:

“If the remote site has been re-imaged or reconfigured, it may have a new cluster incarnation ID. In such cases, the remote site configuration must be recreated to align with the current cluster information.”

Steps like checking ping with MTU 9000 (D) are not directly related to remote site connectivity for replication, and NAT configurations (B) are generally not recommended unless explicitly required.

CPU Ready Time indicates how long a VM waits for CPU resources due to contention.

Option B (Review host CPU utilization) is correct:

IfCPU utilization is high, there may beexcessive CPU overcommitment, leading to high CPU Ready Time.

Adding more hostsorreducing vCPU allocationsmay resolve the issue.

Option A (Check CVM vCPUs) is incorrect:

The Controller VM (CVM)does not directly impact application VM performancein this case.

Option C (Assess SSD capacity) is incorrect:

CPU Ready Time is unrelated to storage performance.

Option D (Enable VM memory oversubscription) is incorrect:

Memory oversubscription does not affect CPU contention.

In Nutanix Prism Central, user-generated reports in Intelligent Operations are stored for a limited time and then deleted automatically.

Option C (Reports are automatically deleted after 24 hours) is correct:

Reportsdo not persist indefinitelyunless they arescheduled reports.

One-time reports expire after 24 hours.

Option A (Cluster Viewer deleted the report) is incorrect:

Cluster Viewerdoes not have permissions to delete reports.

Option B (Report was archived) is incorrect:

Nutanixdoes not automatically archive reports.

Option D (Report stored in Prism Element) is incorrect:

Reportsare generated and stored only in Prism Central, not Prism Element.

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.
