Pass the Nutanix NCM-MCI NCP-MCI-6.10 Questions and answers with ValidTests

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.

A cluster runway below 365 days does not necessarily indicate an issue if Intelligent Operations determines that workloads are sustainable.

Option B (Because new workloads are sustainable) is correct:

Nutanixanalyzes resource trendsand marks clusters as healthyif new workloads are within projected capacity.

Option A (Storage Runway is still good) is incorrect:

Storage isone component, butCPU and memoryalso affect runway calculations.

Option C (Recommended resources) is incorrect:

Recommendations help optimize capacity, butdo not define cluster health.

Option D (Target is 1 month) is incorrect:

The scenario’s target window does not impact the actual runway calculation.

For optimal Disaster Recovery performance, new nodes must match or exceed the storage performance of existing nodes.

Option A (New node must have at least 2 SSDs) is correct:

Since the G7 nodes havetwo SSDs, replacing G5 nodes withat least 2 SSDsensuresconsistent SSD cache and performance.

Option B is incorrect:

G7 or G8 nodes may help, but storage performance is more critical for DR.

Option C is incorrect:

CPU core count does not impact DR storage performance as much as SSD capacity.

Option D is incorrect:

Hybrid nodes are already in use, but SSDs must match for performance balance.

When creating a storage container in Nutanix, the administrator must configure the correctcapacity settings:

Option A (Prism Element with Advertised Capacity of 100 GiB) is correct:

Advertised Capacitydefineslogical limitsfor the container (i.e., how much space it reports as available).

Inline Compressioncan be enabled directly in Prism Element.

Option B (Create in Prism Element without Advertised Capacity)is incorrect:

Without specifyingAdvertised Capacity, the container may consume unlimited storage.

Option C (Create in Prism Central with Reserved Capacity)is incorrect:

Reserved Capacityapplies toQuality of Service (QoS) policies, not storage limits.

Option D (Create in Prism Central without capacity limits)is incorrect:

Prism Central can manage storage but does not directly enforceRF1 and compression policies.

For high-performance databases like MySQL, optimizing storage access is critical.

Option B (Create additional vDisks for SQL data) is correct:

Multiple vDisks allowbetter parallelismin NutanixDSF (Distributed Storage Fabric), improving IOPS.

Option C (Use LVM to stripe SQL data across multiple vDisks) is correct:

Striping across multiple disksdistributes the load, reducing latency.

Option A (Thick provisioned vDisks) is incorrect:

Nutanixalways provisions vDisks thinly, and thick provisioningdoes not improve IOPS.

Option D (Thin provisioned vDisks) is incorrect:

All Nutanix vDisksare thin-provisioned by default.

Nutanix uses IPv4 multicast for automatic node discovery and cluster expansion.

Option D (IPv4 multicast must be allowed) is correct:

When adding new nodes,the Nutanix Cluster automatically detects themusingIPv4 multicast traffic.

If multicast isblocked at the switch level, the new nodeswill not be discoveredautomatically.

Option A (Hypervisor version must match) is incorrect:

While thehypervisor version should be compatible, itdoes not impact node discovery.

Option B (IPv6 multicast) is incorrect:

Nutanixdoes not use IPv6 multicast for cluster discovery.

Option C (AOS version must match) is incorrect:

Nodes can haveslightly different AOS versions, butdiscovery still works as long as they are compatible.

Data-in-Transit Encryption in Nutanix requires inter-node communication over specific CVM ports.

Option A (Port 2009) is correct:

Port2009 is used for Data-in-Transit Encryption between Nutanix CVMs.

Firewall rules must allow traffic on this portto enable secure encrypted communication.

Option B (Port 2010) is incorrect:

Port2010 is used for CVM-to-CVM communication but does not handle encryption.

Option C (Port 2020) is incorrect:

This port is used forAcropolis File Services (AFS), not encryption.

Option D (Port 9440) is incorrect:

Port9440 is used for Prism Central web access, not internal CVM encryption.

A single vCPU is likely causing a bottleneck, limiting the VM’s ability to process I/O requests efficiently.

Option D (Increase the VM’s number of vCPUs) is correct:

Windowsrequires sufficient CPU resourcesto handle disk and network operations.

Adding more vCPUs allows the VM to process more I/O operations simultaneously, improving performance.

Option A is incorrect:

AdditionalvSCSI controllers are only useful for very high disk I/O workloads.

Option B is incorrect:

Balance-TCP applies to network traffic, not storage performance.

Option C is incorrect:

CVM resources do not directly affect individual VM performance.

When diagnosing CPU performance issues, CPU Ready Time and CPU Usage are the key indicators of whether more vCPUs are needed.

Option A (VM CPU Ready Time) is correct:

High CPU Ready Time means the VM is waiting for CPU resources, indicatingCPU contention.

Option B (VM CPU Usage) is correct:

If CPU usage isconsistently high, adding more vCPUsmay improve performance.

Option C (Host CPU Usage) is incorrect:

Host-wide CPU usage does not indicate whether a specific VM needs more vCPUs.

Option D (Host Memory Swap Out Rate) is incorrect:

Memory swappingaffects RAM performance, not CPU allocation.

Active-Active bonding allows multiple network interfaces to be used simultaneously, improving bandwidth and redundancy.

Option B (Active-Active) is correct:

This mode enablesload balancing across all available adapters, providinghigher throughput and fault tolerance.

Option A (No Uplink Bond) is incorrect:

Without a bond, VMscannot benefit from multiple adapters.

Option C (Active-Active with MAC pinning) is incorrect:

MAC pinningbinds traffic to a single NIC, limiting bandwidth distribution.

Option D (Active-Backup) is incorrect:

This modeonly provides failover, not increased bandwidth.
