NCP‐MCA_14 - itnett/FTD02H-N GitHub Wiki

Let's create a comprehensive mock exam (MOC) for the Nutanix NCP-MCA certification using the same style and format of questions. Each question will include detailed explanations for why each alternative is correct or incorrect, providing you with a deep understanding of the concepts being tested.

Mock Exam: Nutanix NCP-MCA Certification

Question 1:

The Playbook is designed to execute a script, in order to fix a known problem in the application. However, it keeps failing. Why is this Playbook continuing to fail?

  • A. Slack configuration should be reviewed.
    Incorrect. Slack configuration does not impact the execution of a script designed to fix an application problem. The failure is likely related to the script execution itself, not the notification action.

  • B. The script is incorrect.
    Correct. If the script being executed contains syntax errors or incorrect logic, the Playbook will fail at the script execution step. The administrator should check the script for any mistakes or errors.

  • C. The Playbook actions are in the wrong order.
    Possible but Less Likely. While the order of actions can affect the outcome, the failure would be more directly related to the script itself if it is not executing correctly.

  • D. Not enough storage space to take a snapshot.
    Incorrect. This option could cause the snapshot action to fail, but it is not directly related to the failure of the script execution.

Correct Answer: B. The script is incorrect.

  • Explanation: The most direct cause of failure for a script execution step is that the script itself is incorrect. The administrator should review the script for syntax errors, incorrect commands, or logic problems.

Question 2:

Which action should an administrator use to request a static IP address from an IPAM solution?

  • A. Create
    Correct. The "Create" action is used to request or allocate new resources, such as a static IP address from an IPAM solution. This action initiates a request to the IPAM to reserve a specific IP address.

  • B. Guest Customization
    Incorrect. Guest customization deals with settings within the guest operating system of a VM, such as setting a hostname or configuring network settings, but it does not request a static IP from an IPAM solution.

  • C. Pre-create
    Incorrect. "Pre-create" is used for tasks that need to be executed before a main task starts, not for making requests to external systems like IPAM.

  • D. Profile
    Incorrect. "Profile" is not an action used to request a static IP from an IPAM solution. Profiles are generally used to define settings or configurations.

Correct Answer: A. Create.

  • Explanation: The "Create" action is specifically designed for requesting resources like a static IP address from an IPAM solution.

Question 3:

What needs to be done in order to enable the developer to complete this requested task? (Choose two.)

  • A. Create AWS and Azure Providers
    Correct. To use AWS and Azure resources within Calm, you must first create the respective cloud providers in the Calm environment. This involves configuring the credentials and access settings for these cloud platforms.

  • B. Add the Providers to the Project
    Correct. After creating the cloud providers, they need to be associated with a specific project in Calm. This enables the project's users to utilize these providers for deployments.

  • C. Enable Environment for AWS and Azure
    Incorrect. This step is not specific and does not refer to any particular configuration required once the providers are set up and associated with the project.

  • D. Upgrade Calm to version 3.2.x
    Incorrect. Upgrading Calm is unnecessary unless a specific feature required for the task is only available in version 3.2.x, which is not stated in the question.

Correct Answers: A. Create AWS and Azure Providers & B. Add the Providers to the Project.

  • Explanation: To enable the developer to complete the task, AWS and Azure providers must be created and then added to the project so they can be used for deployments.

Question 4:

A company is new to automation and has infrastructure they would like to automate with Calm to provide standardized automation. The company also wants to create a Hybrid Cloud environment with their existing infrastructure, which includes AHV, Azure, AWS, and a small legacy vSphere environment. In which two locations can Calm be deployed? (Choose two.)

  • A. vSphere Essential Edition
    Incorrect. Calm cannot be deployed on vSphere Essential Edition due to the limitations of this edition, which lacks the necessary API and automation support.

  • B. VMware ESXi
    Correct. Calm can be deployed in a VMware ESXi environment, provided that the environment supports the necessary APIs and features required by Calm.

  • C. Nutanix AHV
    Correct. Calm is natively supported on Nutanix AHV and is often deployed within Nutanix environments to leverage its full functionality.

  • D. Any Public Cloud
    Incorrect. Calm cannot be directly deployed in a public cloud like AWS or Azure. It manages resources across these clouds but is not itself a cloud-native service.

Correct Answers: B. VMware ESXi & C. Nutanix AHV.

  • Explanation: Calm can be deployed in environments that support its requirements, such as Nutanix AHV and VMware ESXi.

Question 5:

An administrator wants to be alerted when production VMs become idle. The VMs will be determined to be idle when CPU usage is lower than 5% for more than 5 minutes. All affected VMs are categorized as Environment:Production, since they have Flow microsegmentation rules. What should the administrator do to satisfy this requirement?

  • A. Create an alert for all VMs, create a Playbook with this alert as the trigger and send an email as the action.
    Incorrect. This option creates alerts for all VMs, not just those in the "Environment:Production" category, leading to unnecessary alerts.

  • B. Create an alert for VMs in the correct category, create a Playbook with this alert as the trigger > take a snapshot > send an email as the action.
    Incorrect. Taking a snapshot is not necessary in this context and adds unnecessary overhead.

  • C. Create an alert for all VMs, create a Playbook with this alert as the trigger > reduce 1 CPU > send an email as the action.
    Incorrect. Reducing a CPU is not an appropriate response to an idle VM; the task is to notify, not to modify VM resources.

  • D. Create an alert for VMs in the correct category, create a Playbook with this alert as the trigger and send an email as the action.
    Correct. This option targets only VMs in the "Environment:Production" category and sends an email alert when they become idle.

Correct Answer: D. Create an alert for VMs in the correct category, create a Playbook with this alert as the trigger and send an email as the action.

  • Explanation: The correct answer involves creating an alert for the specific category of VMs and sending an email notification, aligning with the administrator's requirement.

Question 6:

When creating a blueprint, which Pre-create and Post-delete tasks are valid?

  • a) Create, Start, Stop, Delete
    Incorrect. These are general actions related to managing the lifecycle of VMs, not specific Pre-create or Post-delete tasks.

  • b) Execute, Set variable, HTTP, Delay
    Correct. These tasks are valid for Pre-create and Post-delete actions in a blueprint. They provide flexibility and control over automation processes, such as executing scripts, setting variables, making HTTP requests, and adding delays.

  • c) Create, Start, Stop, Soft Delete
    Incorrect. These actions do not specifically relate to the Pre-create or Post-delete task types.

  • d) Execute, Set variable, API, Delay
    Incorrect. While close, "API" is not the correct term; "HTTP" is the proper action for interacting with external services.

Correct Answer: b) Execute, Set variable, HTTP, Delay.

  • Explanation: These actions are specifically designed for tasks that should occur before or after the main blueprint deployment steps.

Additional Questions

Question 7:

When a developer launches the created Blueprint within the Blueprint Editor, the application gets deployed correctly. However, when the Blueprint is launched via Marketplace, it gets a check login error. What is causing this issue?

  • a) Prism Central can't communicate with Active Directory.
    Incorrect. While this could cause authentication issues, it would likely prevent both deployments, not just the Marketplace deployment.

  • b) The SSH key within the user's laptop is not valid.
    Incorrect. This is unrelated to the specific error mentioned (check login error).

  • c) User is not authorized to launch Blueprints.
    Incorrect. If the user could launch the Blueprint in the Editor, authorization is not the problem.

  • d) The credential in the Project Environment is invalid.
    Correct. The most likely cause of a check login error is an invalid credential configured in the Project Environment.

Correct Answer: d) The credential in the Project Environment is invalid.

  • Explanation: If the credential stored in the Project Environment is incorrect or expired, this would cause authentication failures specifically when launched from the Marketplace.

Question 8:

Which action should an administrator take to ensure a consistent application deployment using Calm Blueprints?

  • a) Use default credentials.
    Incorrect. Using default credentials can lead to security vulnerabilities and is not a best practice for consistent or secure deployments.

  • b) Use version-controlled blueprints.
    Correct. Version control ensures that the blueprint remains consistent across different deployments and environments.

  • c) Allow users to modify blueprints.
    Incorrect. Allowing multiple users to modify blueprints can lead to inconsistencies and errors in deployment.

  • d) Disable blueprint updates.
    Incorrect. While this prevents changes, it also prevents necessary updates and improvements.

Correct Answer: b) Use version-controlled blueprints.

  • Explanation: Version-controlled blueprints ensure consistency and allow for controlled updates, which is essential for reliable deployments.
