Vce NCP-CN Questions Latest

The documentation confirms that when a new license is activated to upgrade to a higher tier, users mustlog out and log back infor the license changes to take effect. This ensures that updated entitlements are loaded into the UI and CLI environment.

Exact extract from documentation:

“After applying a new license for a higher-tier product, log out and log back in to see and activate the newly available features.”

As per theNKPA 6.10 documentation, the standard and supported approach for installing Kommander on an NKP cluster is using theNKP CLI. The CLI provides commands for deploying Kommander and associated platform components as part of the cluster lifecycle management workflow.

Key Reference:

“The recommended approach to deploy Kommander is by using the nkp CLI, which ensures compatibility and streamlined installation with the rest of the Nutanix Kubernetes Platform stack.”

For deploying NKP clusters in AWS, setting theAWS_REGIONenvironment variable is a key prerequisite to ensure that the AWS CLI and underlying deployment scripts know which region to target. This is essential for provisioning instances using the specified AMI.

Exact extract:

“Set the AWS_REGION environment variable to the appropriate region prior to deploying clusters to ensure proper interaction with the AWS API.”

The Kubernetes Image Builder (KIB) is used to create CAPI-compliant machine images for NKP cluster nodes, often leveraging tools likePackerto build AMIs for AWS. When the KIB process fails, troubleshooting requires detailed logs to identify the root cause. The NKPA course recommends increasing the verbosity of the KIB command to capture detailed output, including AWS CLI commands and their responses.

The correct troubleshooting step is torerun the KIB command with the verbosity level set to debug. This is typically done using the --verbose or -v flag (e.g., -v debug) to enable debug-level logging, which includes all AWS CLI commands, their outputs, and errors, written to a log file for review. The Nutanix Cloud Native (NCP-CN) 6.10 Study Guide states: “To troubleshoot KIB failures, rerun the command with debug verbosity (-v debug) to log all operations, including AWS CLI interactions, to an exported log file for detailed analysis.” This approach helps pinpoint issues like permission errors, misconfigurations, or failures in image bundle uploads.

Incorrect Options:

A. Rerun with pause parameter: KIB does not support a pause parameter for step-by-step review, as per the NKPA course.

C. Instruct Packer not to delete the cloned AMI: While preserving the AMI can help, the course prioritizes debug logging for initial troubleshooting. Packer’s --on-error=abort flag exists, but it’s less direct than debug logs.

D. Instruct Ansible not to delete the cloned AMI: KIB primarily uses Packer, not Ansible, for AMI creation, making this option incorrect.
