Question No : 1

An administrator is configuring a replication schedule on multiple remote locations deployed using a single-node cluster. The goal is to achieve the lowest possible RPO (Recovery Point Objective).
How should the administrator configure the replication schedule?

A.Configure NearSync replication.
B.Configure a schedule for 16 minutes up to 59 minutes.
C.Configure Async replication.
D.Configure a schedule for 1 minute up to 15 minutes.

정답:
Explanation:
Nutanix NearSync replication provides the lowest RPO (as low as 1 minute) and is the best option for minimizing data loss in DR scenarios.
Option D (Configure a schedule for 1 minute up to 15 minutes) is correct:
NearSync allows an RPO as low as 1 minute, providing near-continuous data protection.
This is ideal for mission-critical applications where minimal data loss is required.
Option A (Configure NearSync) is incorrect:
While NearSync is the best choice, just enabling it is not enough―the schedule must be set to 1-15 minutes.
Option B (16 to 59 minutes) is incorrect:
NearSync operates within a 1-15 minute range. If set above 15 minutes, it defaults to Async replication.
Option C (Async replication) is incorrect:
Async replication typically has an RPO of 1 hour or more, which does not meet the lowest RPO requirement.

Option A (Target host must have sufficient resources) is correct:
The target host must have the same GPU model and enough available resources to support the VM.
vGPU cannot be live-migrated across incompatible hardware.
Option B (vGPU profile change) is incorrect:
The profile does not need to be changed as long as the target host has the same configuration.
Option C (Agent VM required) is incorrect:
Agent VMs are not necessary for vGPU migration.
Option D (Host affinity) is incorrect:
Host affinity limits movement, but is not a prerequisite for migration.
Reference: Nutanix AHV Best Practices → Migrating vGPU-Enabled VMs Nutanix KB → Requirements for Live-Migrating vGPU VMs

Question No : 6

In an RF2 cluster, what is the minimum number of nodes required to allow a host removal?

A.2
B.3
C.4
D.5

정답:
Explanation:
Replication Factor (RF2) means that each piece of data is stored twice across different nodes to ensure availability.
Option B (3 nodes) is correct:
In an RF2 cluster, data redundancy requires at least three nodes to ensure data protection when one node is removed.
If a node is removed from a 3-node cluster, Nutanix automatically redistributes data across the remaining nodes.
Option A (2 nodes) is incorrect:
RF2 requires at least three nodes to maintain fault tolerance.
A 2-node cluster cannot provide full redundancy without a Witness node.
Option C (4 nodes) and Option D (5 nodes) are incorrect:
While larger clusters provide more redundancy, the minimum requirement is 3 nodes.

Question No : 7

An administrator is working with a local network engineer to design the network architecture for a Disaster Recovery (DR) failover. Because DNS is well designed and implemented, DR will utilize a different subnet from production. To make the planning and execution easy to implement, the network engineer would like to utilize the same last octet in DR. What is the best way to achieve this?

A.Use a custom script to update the IP address after instantiation in D
B.Set up IPAM so the address is dynamically assigned during D
C.Manually log into VMs after the DR event and update the last octet.
D.Utilize Recovery Plan Offset-based IP mapping.

정답:
Explanation:
Offset-based IP mapping in Nutanix Recovery Plans allows automatic subnet changes during DR failover.
Option D (Utilize Recovery Plan Offset-based IP mapping) is correct:
This method automatically adjusts the IP range while keeping the same last octet.
It eliminates the need for manual intervention after failover.
Option A (Custom script) is incorrect:
Scripting is an option, but Recovery Plan IP mapping is simpler and native to Nutanix.
Option B (Use IPAM) is incorrect:
IP Address Management (IPAM) is useful, but offset-based mapping provides more control.
Option C (Manually update IPs) is incorrect:
This would be time-consuming and error-prone.

A.Utilize a VM naming schema that allows sorting
B.Utilize Categories to organize VMs in Recovery Plans
C.Utilize a 1:10 ratio of Recovery Plan to VMs
D.Utilize RESTful APIs to script creation of Recovery Plans

정답:
Explanation:
Nutanix Categories allow administrators to group related VMs, making Disaster Recovery (DR) planning easier.
Option B (Utilize Categories to organize VMs in Recovery Plans) is correct:
Categories help group VMs based on application tiers (e.g., database, middleware, web servers).
This ensures orderly failover while maintaining application dependencies.
Option A (Naming schema) is incorrect:
Naming conventions help, but they do not provide functional organization in recovery plans.
Option C (1:10 Recovery Plan to VMs) is incorrect:
The ratio depends on business requirements, not a fixed number.
Option D (RESTful APIs) is incorrect:
Automation is useful, but it does not replace proper VM grouping via categories.

Question No : 11

A security team asks an administrator to set up port mirroring of a specific source VM to a target VM.
What must the administrator ensure for this configuration to be possible?

A.Source VM and Target VM are on the same VLA
B.Source VM and Target VM are on the same host.
C.Source VM and Target VM are on the same subnet.
D.Source VM and Target VM are on the same VP

정답:
Explanation:
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 mirroring only works within a single host because 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 is not a requirement for port mirroring.
Option C (Same subnet) is incorrect:
Port mirroring happens at the 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.

Question No : 12

Refer to Exhibit:

An administrator sees the alert shown in the exhibit.
What should the administrator do to ensure the nutanix user can no longer SSH to a CVM using a password?

A.Rename the nutanix user.
B.Block port 22 on the CVM firewall.
C.Enable Cluster Lockdown.
D.Delete the nutanix user.

정답:
Explanation:
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 Reference & 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.
