Nutanix NCP-MCI-6.10 Exam Dumps

C.   The destination storage container is not empty.


D.   Both storage containers must have the same name.

Answer DescriptionExplanation: Metro Availability in Nutanix requires that the primary and secondary storage containers be configured identicallyto ensuredata replication consistency.
Option C (The destination storage container is not empty) is correct:
Option D (Both storage containers must have the same name) is correct:
Option A is incorrect: Metro Availability works regardless of hardware vendor differences.
Option B is incorrect:Compression does not affect compatibilitybut may impact performance.

A.   Load balancing

Answer DescriptionExplanation:
When using FQDN instead of a Virtual IP in a scale-out Prism Central deployment, Nutanix enables load balancing across multiple Prism Central instances.
Option A (Load balancing) is correct because it ensures that requests are distributed among multiple Prism Central nodes, improving performance and redundancy.
Option B (Resiliency) is incorrect because resiliency is achieved through HA and replication, not through FQDN configuration.
Option C (Segmentation) is incorrect because network segmentation is handled at the VLAN or security policy level.
Option D (SSL Certificate) is incorrect because SSL certificates can be applied regardless of whether FQDN or Virtual IP is used.

B.   8GB

Answer DescriptionExplanation:
Understanding the Exhibit & Memory Allocation
The host has 128GB of physical RAM.
The current memory allocation a cross three VMs (VM1, VM2, VM3) is 128GB, but only92GB is actually utilized.
This means there is36GB of unutilized memory available for allocation.
Step-by-Step Breakdown
Existing Memory Usage Before Adding VM4
After Creating and Running VM4
Maximum Memory Allocation for VM5
Evaluating the Answer Choices
(A) 4GB(Incorrect)
(B) 8GB(Correct)
(C) 16GB(Incorrect)
(D) 32GB(Incorrect)
Key Concept: Nutanix Memory Overcommit
Nutanix AHV supports memory overcommit, meaning VMs can be allocated more memory than physically available using memory ballooning and swapping.
However, to power on VM5 without impacting performance, it must fit within the available unutilized memory, which is 8GB.

C.   Enable Cluster Lockdown.

Answer DescriptionExplanation:
Understanding the Exhibit & the Alert
The alert states:
"The cluster is using password-based SSH access for the CVM."
"Password-based remote login is enabled on the cluster."
"It is recommended to use key-based SSH access instead of password-based SSH access for better security."
This means that the nutanix user can log in to Controller VMs (CVMs) using a password, which is a security risk.
Corrective Action: Enabling Cluster Lockdown
(C) Enable Cluster Lockdown. (Correct Answer)
Cluster Lockdown Mode restricts password-based SSH access and forces keybased authentication.
This prevents users from logging into CVMs using passwords, enhancing cluster security.
To enable Cluster Lockdown:
Evaluating the Other Answer Choices
(A) Rename the nutanix user. (Incorrect)
The nutanix user is a built-in system account required for cluster operations.
Renaming the user will not prevent SSH access via password.
(B) Block port 22 on the CVM firewall. (Incorrect)
Blocking port 22 (SSH) will completely disable SSH access, including key-based authentication.
This may break cluster management and troubleshooting operations.
(D) Delete the nutanix user. (Incorrect)
The nutanix user is a critical system account required for cluster functionality.
Deleting the account will cause serious issues with cluster management.

D.   It is the usable capacity based on cluster configuration options.

Answer DescriptionExplanation:
The Prism Central Memory Cluster Runway Diagram provides insights into memory usage trends, predicting how long the cluster can sustain workloads before exhausting resources.
The solid blue area represents the actual memory consumption over time.
The dotted red liner presents the effective memory capacity limit based on the cluster's current configuration.
Analyzing the Dotted Red Line
The dotted red line is labeled "Effective Capacity: 503.22 GiB", which means:
It is the total usable memory capacity IN the cluster after considering hypervisor overhead, redundancy settings, and failover capacity.
This value is not a hard limit but an indication of the available memory before potential performance issues occur. 
Evaluating the Answer Choices
(A) It is the default trend analysis static threshold that can be manually set.(Incorrect ) The dotted red line is not a static threshold that an administrator can manually configure.
Trend analysis in Prism is dynamic and based on workload history and projections.
(B) It is the maximum memory the administrator can assign to VMs.(Incorrect) Administrators can over subscribe memory beyond the dotted red line if memory over commitment is enabled.
However, oversubscribing memory beyond effective capacity may impact performance.
(C) It is the calculated memory oversubscription limit for currently running VMs.( Incorrect)
The dotted red line does not represent oversubscription limits.
Memory oversubscription depends on hypervisor memory ballooning, compression, and swapping mechanisms, which are not directly shown here.
(D) It is the usable capacity based on cluster configuration options.(Correct Answer)
The dotted red line (503.22 GiB)represents the actual usable memory available in the cluster after factoring in system overhead.

C.   Perform an Inventory Scan.

Answer DescriptionExplanation:
When Life Cycle Manager (LCM) reports that a newer framework version is available, the correct action is to perform an inventory scan (Option C).
Performing an inventory scan updates the available firmware/software versions and allows LCM to download required updates.
Option A (Run an AOS upgrade)is unrelated to the LCM framework update process.
Option B (Run an AHV upgrade)is a separate component update and does not affect the LCM framework.
Option D (Download manually from a CVM)is not necessary because LCM updates are automatically pulled after an inventory scan.

B.   Because new workloads are sustainable.

Answer DescriptionExplanation:
In Nutanix Capacity Planning, Overall Runway represents how long the cluster can support current and new workloads before resources are exhausted.
Even if the runway is below 365 days, the system considers the cluster to be in good shape if new workloads are sustainable (Option B).
Option A is incorrect: Storage runway alone is not the only factor; CPU and memory are equally important.
Option C is incorrect: The presence of recommended resources does not mean the cluster is in good shape.
Option D is incorrect: The target of 1 month affects projections but does not explain why the cluster is in good shape.

B.   Review host CPU utilization.

Answer DescriptionExplanation:
Understanding the Issue
The administrator is investigating VM performance complaints and is analyzing CPU Ready Time data.
CPU Ready Time is a crucial metric in Nutanix and virtualization environments (AHV, ESXi, or Hyper-V).
It measures the amount of time a VM is waiting for CPU scheduling due to resource contention.
High CPU Ready Time indicates that VMs are ready to run but are waiting because the host lacks available CPU resources.
Analysis of the Exhibit
The graph shows CPU Ready Time spikes for multiple VMs.
Some VMs have CPU Ready Time exceeding 18% to 21.5%, which is very high.
A healthy CPU Ready Time should be below 5%.
Values above 10% indicate CPU contention, and anything above 20% is critical and requires immediate troubleshooting.
Evaluating the Answer Choices
(A) Check the number of vCPUs assigned to each CVM. (Incorrect)
CVMs (Controller VMs) have fixed CPU allocation, and modifying their vCPU count is not recommended unless advised by Nutanix Support.
The issue is related to VM CPU contention, not CVM configuration.
(B) Review host CPU utilization. (Correct Answer)
High CPU Ready Time suggests CPU over commitment or host saturation.
The administrator should check host CPU usage in Prism Central to determine if the cluster is overloaded.
If host CPU usage is consistently above 85–90%, VMs are competing for CPU resources, leading to high CPU Ready Time.
(C) Assess cluster SSD capacity. (Incorrect)
SSD capacity impacts storage performance (latency, read/write speeds) but does not affect CPU Ready Time.
High CPU Ready Time is a CPU scheduling issue, not a storage bottleneck.
(D) Enable VM memory oversubscription. (Incorrect)
Memory oversubscription does not impact CPU scheduling.
Enabling memory oversubscription affects RAM allocation, but CPU Ready Time is strictly related to CPU contention.
