📝 Nutanix NCP-MCA 6.5 Exam Cram Sheet (Continued)

🎯 Objective 3: Validate Blueprints, Runbooks, Playbooks, and Automation Settings

📘 3.1 Validate Blueprints, Runbooks, Playbooks, and Automation Settings

  • Key Concepts:

    • Blueprint Validation: Ensure that all configurations, tasks, and dependencies within the blueprint are set correctly. This includes checking that all required inputs are provided and that scripts or tasks do not contain errors.
    • 🔍 Runbook Validation: Verify that runbooks are correctly set up with the appropriate tasks, triggers, and dependencies. Ensure that each task is tested individually and in sequence.
    • ⚙️ Playbook Validation: Confirm that playbooks are correctly configured, with accurate triggers and actions, and that they perform as expected when activated.
    • 🛠️ Automation Settings Check: Ensure that all settings related to automation (e.g., alert policies, schedules, integration points) are correctly configured and tested.
  • 🛠️ Tools to Know:

    • 📋 Validation Tools in Calm: Use built-in validation tools to check for errors or warnings in blueprints, runbooks, and playbooks.
    • 🔧 Error Logging and Troubleshooting: Familiarize yourself with logs and diagnostic tools for debugging and error resolution.
    • 🔄 Test Environments: Use a test environment to validate automation settings without affecting production.
  • 📚 Key Resources:

  • 💡 Quick Tips:

    • Use Validation Tools: Regularly use the built-in validation tools in Calm to check blueprints, runbooks, and playbooks for any errors or misconfigurations.
    • 🔄 Test in Non-Production Environments: Always test new or updated automation settings in a non-production environment before applying them to production.
    • 🛠️ Check Logs for Errors: Use log files to troubleshoot any errors or unexpected behavior in automation workflows.

📘 3.2 Validate Blueprints for Application Deployment and Configuration

  • Key Concepts:

    • 🔄 Dynamic Blueprints: Ensure blueprints can handle dynamic changes such as scaling, updates, or application-specific configurations.
    • 🧩 Substrates and Infrastructure Configurations: Validate that substrates (e.g., cloud providers, AHV) are correctly configured and compatible with the deployment blueprint.
    • 🔧 Task Execution: Verify that all tasks within a blueprint (e.g., install, configure, deploy) execute in the correct order without errors.
    • 📋 Resource Requirements: Check that the blueprint specifies the correct resources (e.g., CPU, RAM, disk) and that these requirements are met by the infrastructure.
  • 🛠️ Tools to Know:

    • 📋 Blueprint Designer: Use the designer to visually validate blueprint components and their configurations.
    • 🔧 Calm Console: Verify blueprint deployment parameters and test deployment in Calm.
    • 🖥️ Resource Monitors: Check resource usage and ensure that it aligns with the specifications in the blueprint.
  • 📚 Key Resources:

  • 💡 Quick Tips:

    • 📘 Check Task Order: Ensure tasks in blueprints are ordered correctly and dependencies are managed.
    • 🔧 Validate Substrates: Verify that substrates like cloud environments or AHV are correctly set up and compatible.
    • 🖥️ Monitor Resources: Use resource monitors to check that the blueprint’s resource requirements are met during deployment.

📘 3.3 Validate Runbooks and Automation Settings for Operational Consistency

  • Key Concepts:

    • 🔄 Operational Tasks: Ensure runbooks perform operational tasks correctly, such as VM provisioning, decommissioning, and patch management.
    • 🔧 Task Types and Actions: Validate that all tasks in a runbook are set up correctly (e.g., SSH commands, API calls) and perform as intended.
    • 📅 Scheduled Runbooks: Confirm that scheduled runbooks execute at the right time and frequency.
    • 🚀 Runbook Execution: Test runbooks to ensure they complete without errors and achieve the desired outcome.
  • 🛠️ Tools to Know:

    • 🔍 Runbook Validation Tools: Use Calm's tools to validate and troubleshoot runbooks.
    • Scheduler: Verify the scheduling settings for runbooks to ensure they trigger at the correct times.
    • 📊 Runbook Logs: Check logs to diagnose any errors or unexpected behavior during execution.
  • 📚 Key Resources:

  • 💡 Quick Tips:

    • 🔍 Test Runbooks Thoroughly: Validate each step in a runbook to ensure it performs correctly.
    • Check Scheduler Configurations: Confirm that all scheduled tasks are correctly configured to run at the expected times.
    • 📊 Review Logs Regularly: Use runbook logs to identify and fix any issues or unexpected behavior.

🛠️ Troubleshooting Tips: Common Issues and Resolutions

Issue Possible Cause Resolution
Blueprint Deployment Fails Incorrect configurations or missing tasks. Review task dependencies and scripts.
Playbook Not Triggering Misconfigured triggers or alert policies. Validate alert policies and trigger conditions.
Integration Errors (e.g., ServiceNow) Incorrect API keys or integration settings. Verify API keys, endpoint URLs, and user permissions.
Category Not Applied Correctly Misconfiguration of categories or policies. Check category assignments and policy mappings.
Quota Exceeded Error Resource quotas set too low. Adjust quotas within the project settings.

| Approval Policy Not Enforced | Incorrect policy configuration or missing conditions. | Review and correct the policy conditions. | | Runbook Fails to Execute | Task errors, incorrect API calls, or scheduling issues. | Validate each task, check API syntax, and verify the schedule. |
