Important Nutanix NCP-CI-AWS Exam Questions

Answer: B

Explanation:

To protect workloads on an NC2 cluster on AWS, deploying strategies that ensure high availability and disaster recovery are essential. The two valid options are:

Create a Second NC2 Cluster in a Different Availability Zone:

High Availability: Deploying a second NC2 cluster in a different availability zone ensures that workloads can be quickly recovered in case of an availability zone failure.

Disaster Recovery: This setup enables asynchronous replication between clusters, providing a robust disaster recovery solution.

Use an Existing On-Prem Nutanix Cluster as a Disaster Recovery Target:

Hybrid DR: Leveraging an existing on-premises Nutanix cluster for disaster recovery provides a cost-effective and efficient DR solution.

Replication: Set up replication policies to ensure data is consistently copied from the NC2 cluster on AWS to the on-premises cluster.

Why Not Other Options:

One-node cluster in another availability zone: Not a valid DR solution as a single-node cluster cannot provide the required resilience and high availability.

Deploy a cluster across two availability zones: While this can enhance availability, it is not a typical approach for Nutanix clusters which are designed to operate within a single availability zone for simplicity and performance reasons.

Answer: D

Explanation:

When configuring a syslog server in the Prism Central Admin Center for Nutanix, one of the available log modules is Acropolis.

The Acropolis module logs system events related to the Nutanix Acropolis operating system, which is critical for monitoring and auditing system activities and performance.

Configuring syslog with the Acropolis module ensures that important events and issues related to the Acropolis environment are captured and can be forwarded to an external syslog server for centralized logging and analysis.

Reference: Refer to the Nutanix documentation on Prism Central and syslog configuration for the full list of available log modules and detailed steps for configuration.

Answer: B

Explanation:

To SSH into a Controller VM (CVM) in an NC2 on AWS cluster without on-premises connectivity, the administrator needs to ensure that the security settings allow SSH access from the Jump Host. This involves editing the User Management Network Security Group to permit SSH traffic from the Jump Host IP.

Deploy Jump Host:

Ensure the Jump Host is deployed in a public subnet with an Elastic IP (EIP) assigned for external access.

Edit User Management Network Security Group:

Locate the security group associated with the user management network.

Modify the inbound rules to allow SSH (port 22) from the Jump Host's IP address. This ensures that the Jump Host can establish an SSH connection to the CVM.

Steps to Edit Security Group:

Navigate to the EC2 dashboard in the AWS Management Console.

Select 'Security Groups' under the 'Network & Security' section.

Find and select the appropriate security group.

Edit the inbound rules to add a new rule:

Type: SSH

Protocol: TCP

Port Range: 22

Source: Custom IP (enter the Jump Host's public IP address)

Additional Configuration:

Ensure that the CVM itself allows SSH connections and that no internal firewall rules block the traffic.

Nutanix Best Practices for Secure Access

Answer: A

Explanation:

To ensure that alert emails are sent properly from Prism Central within an NC2 environment, configuring an SMTP server in the Prism Central settings is required. The SMTP server facilitates the sending of email notifications for alerts and other communications.

SMTP Configuration:

Prism Central requires an SMTP server to send email alerts. This involves specifying the SMTP server address, port, and authentication details if needed.

The configuration must include the email address from which the alerts will be sent and the recipient addresses.

Steps to Configure SMTP Server in Prism Central:

Log in to Prism Central.

Navigate to the 'Settings' menu.

Select 'Email Server' under the 'Alerts' section.

Enter the SMTP server details, including the server address, port, and authentication credentials.

Test the configuration to ensure emails are sent correctly.

Answer: A, C

Explanation:

Ensure the specialist is assigned the RBAC role with proper permissions (Answer A):

Role-Based Access Control (RBAC) ensures that the specialist has the necessary permissions to troubleshoot and manage the NC2 environment. This avoids unnecessary privilege escalations and maintains security.

Confirm the Support Authorization on the organization is set to Full Access (Answer C):

Setting the Support Authorization to Full Access allows the Nutanix support specialist to have the required access to investigate and resolve issues in the environment. This is essential for effective troubleshooting.
