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

In Nutanix Prism Central,categoriesallow administrators togroup and organize entitiesfor management, automation, and policy enforcement.

Alerts (Option B) can be categorizedto group similar system events and create filtering rules.

Virtual Machines (Option C) can be categorizedto apply security policies, automation tasks, and resource allocation rules.

Option A (Storage Containers) cannot be categorizedin Prism Central. Storage policies apply at the container level but are not managed via categories.

Option D (ISO Images) cannot be categorizedbecause ISOs arestatic objects, not active entities.

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.

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 key-based authentication.

This prevents users from logging into CVMs using passwords, enhancing cluster security.

To enable Cluster Lockdown:

Go to Prism Central or Prism Element.

Navigate to Settings → Security → Cluster Lockdown.

Enable Cluster Lockdown Mode.

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.

Multicloud Infrastructure References & Best Practices

Nutanix Security Best Practices:

Always use key-based SSH authentication instead of password-based logins.

Enable Cluster Lockdown Mode to enforce security policies.

Regularly audit user access to ensure security compliance.

Cluster Lockdown Benefits:

Prevents unauthorized SSH access via passwords.

Enforces public key authentication, reducing brute-force attack risks.

Strengthens CVM security against potential exploits.

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.

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 templates in Nutanix, Prism Central supports two official, built-in guest customization frameworks depending on the operating system family.

The Nutanix guest customization documentation states:

“For Windows VMs, Prism Central supports Sysprep-based customization. For Linux VMs, Prism Central supports Cloud-init customization.”

These two tools allow automation of hostname assignment, networking configuration, user accounts, and post-deployment initialization.

Additional extracts from internal documentation:

“Sysprep is automatically invoked during clone operations from Windows templates to ensure that the cloned VM receives unique identifiers.”

“Cloud-init is used for Linux templates to allow dynamic provisioning, SSH key injection, and package installation during instantiation.”

Nutanix does not list “Custom Script” or “Guided Script” as valid VM template customization mechanisms. Scripting can be applied after deployment but not as a built-in template customization framework.

Thus, the only valid template customization options are Sysprep and Cloud-init.

The Nutanix ECA course covers various methods for organizing and managing virtual machines (VMs) within a Nutanix environment, particularly in Prism Central. The question focuses on easily grouping a set of VMs, which requires a mechanism that is flexible, scalable, and straightforward to apply across multiple VMs for management, reporting, or policy application.

Extract from Nutanix Enterprise Cloud Administration (ECA) Course Documents:

Module: Prism Central Management, Section: Entity Organization"Tags provide a flexible way to group entities such as VMs in Prism Central. Tags are key-value pairs that can be assigned to VMs to categorize them for management, reporting, or policy enforcement. They are easy to apply and can be used to group VMs dynamically across clusters."

Module: VM Management, Section: Grouping VMs"To group a set of VMs for simplified management, Tags are the recommended approach. Unlike Categories, which are used for role-based access control and policy enforcement, Tags are lightweight and ideal for custom grouping without additional configuration overhead."

Explanation of Options:

A. Catalog ItemsThis is incorrect. Catalog Items in Nutanix are used within the Nutanix Calm or Marketplace to manage application blueprints or service offerings, not for grouping VMs. The ECA course states:"Catalog Items represent deployable applications or services in the Marketplace, not a mechanism for grouping existing VMs."They are unrelated to VM organization.

B. LabelsThis is incorrect. The term "Labels" is not used in Nutanix ECA documentation for grouping VMs. While Labels may be a generic term in other platforms, Nutanix uses "Tags" or "Categories" for similar purposes. The ECA materials do not reference Labels as a feature in Prism Central or Prism Element for VM grouping.

C. ProjectsThis is incorrect. Projects in Nutanix Prism Central are used to manage resources, users, and policies for a group of workloads, typically for multi-tenancy or resource allocation. While VMs can be associated with Projects, this involves additional configuration (e.g., assigning users, quotas, and policies) and is not the easiest way to group VMs. The ECA course notes:"Projects are used for resource governance and multi-tenancy, requiring additional setup compared to Tags for simple VM grouping."

D. TagsThis is the correct answer. Tags are lightweight, user-defined key-value pairs that can be applied to VMs in Prism Central to group them for management, monitoring, or reporting purposes. The ECA course emphasizes that Tags are easy to assign and manage, making them ideal for grouping VMs without the overhead of other mechanisms like Categories or Projects. Tags can be applied to multiple VMs at once and used in searches, dashboards, or scripts.

Supporting Extract:"Tags allow administrators to quickly group VMs by assigning custom key-value pairs, such as ‘Department: HR’ or ‘Environment: Production.’ They are ideal for ad-hoc grouping and can be leveraged in Prism Central for filtering and management tasks."

Additional Context from ECA:

Tags are managed in Prism Central under theEntities > Tagssection, where administrators can create, assign, and manage Tags for VMs and other entities. The ECA course highlights their simplicity:"Tags require minimal configuration and can be applied to VMs in bulk, making them the easiest method for grouping."

Unlike Categories, which are used for policy enforcement (e.g., security or placement policies), Tags are purely for organizational purposes, aligning with the question’s focus on ease of use.

Supporting Reference from Web Results:

The Nutanix Bible (https://www.nutanix.com/go/the-nutanix-bible) aligns with the ECA documentation: "Tags in Prism Central provide a simple and flexible way to organize VMs and other entities, enabling administrators to group resources for management or reporting without complex configurations."

The test_esx_entering_mm_pinned_vms check in an AOS upgrade validates whether there are any pinned VMs on ESXi hosts, which could prevent host maintenance mode transitions.

From theNutanix Enterprise Cloud Administration (ECA)course materials:

“Affinity or anti-affinity rules that pin VMs to specific hosts prevent those VMs from migrating during host maintenance mode entry. This directly triggers a failure in the LCM precheck test_esx_entering_mm_pinned_vms check.”
