Nutanix NCP-MCA Questions Answers

To enforce different configurations for different types of workloads within the same Project, Nutanix Self-Service usesEnvironments.

Environments:These are logical configurations within a Project that map to specific infrastructure settings. An administrator can define multiple environments (e.g., "Development" and "Production") within the "Engineering" project.

Category Assignment:Within each Environment configuration, the administrator can define specificVM Categoriesthat will be automatically applied to any VM provisioned into that environment.

Mapping:

Production Environment:Assign the category Protection: async_1hr_repl (Matches requirement: Asynchronous remote replication every 1 hour).

Development Environment:Assign the category Protection: snap_24_hr (Matches requirement: Daily snapshots).

Execution:When a user launches a blueprint, they select the target Environment (Dev or Prod). The system automatically tags the VMs with the categories defined in that environment, which in turn engages the Protection Policies associated with those tags.

Option B uses the wrong category values (sync_remote_repl instead of async). Options C and D suggest using Playbooks, but the native and most efficient method for applying deployment-time governance in Self-Service is via theProject Environmentsettings.

To efficiently identify the source Blueprint for every VM created during a test, the administrator should utilize the built-inBlueprint Name Macrowithin a Multi-VM structure.

Macro Usage:The macro @@{calm_blueprint_name}@@ automatically resolves to the name of the blueprint being deployed (e.g., "Test_BP_Version_A").

Efficiency:By using aMulti-VM blueprint(which creates all four VMs in one deployment action) and configuring theVM Namefield in the service definition to include this macro (e.g., VM-@@{calm_blueprint_name}@@-@@{calm_array_index}@@), the administrator ensures that every resulting VM is automatically tagged with its source blueprint name in the hypervisor (Prism Element/Central) list.

Why not others:

Option Ainvolves "Single VM Blueprint" and "cloning," which is a manual or secondary process that is less efficient than a native Multi-VM definition.

Option Cuses @@{calm_application_name}@@, which identifies the specificinstance(e.g., "App-1"), not theblueprint design(e.g., "Web-Server-v2") that is being tested.

To configure and enforce resource limits within a Nutanix Self-Service (formerly Calm) project, the specific governance component known as thePolicy Enginemust be active.2

According to the Self-Service Administration and Operations Guide regarding thePolicy Engine and Quotas Overview:

Enabling the Policy Engine:You enable and use the policy engine to enforce resource quota policies for infrastructure resources (compute, memory, and storage) on Nutanix and VMware accounts.3

Prerequisite status:Until the policy engine is enabled in the Admin Center Settings, Prism Central cannot perform any quota checks or validation on resource consumption.4

Availability:The options to define resource quota limits (such as vCPU, Memory, and Disk fields in the Project configuration)appear only when you enable the policy enginein your Prism Central instance.5If the policy engine is not enabled, the Quota section in the Projects pages remains unavailable.6

The "Environment" construct in Nutanix Self-Service is designed specifically to abstract infrastructure details from the end user while ensuring correct placement.

Within a single Project, an administrator can define multipleEnvironments(e.g., "Development" and "Production").

TheDevelopment Environmentis configured to map to theDevelopment Clusterand its associated networks.

TheProduction Environmentis configured to map to theProduction Clusterand its associated networks.

When a blueprint is launched, the user (or the application profile) simply selects the target Environment. The Self-Service engine then automatically directs the provisioning to the specific cluster defined in that Environment's settings, ensuring correct placement without requiring the user to know cluster details or manual intervention.
