To remove old VM snapshots, the task should be completed from theVM dashboardin Prism Element. This dashboard allows administrators to manage virtual machine-related operations, including snapshot creation, deletion, and restoration. Steps include:

Navigate toPrism Element > VM.

Select the VM for which snapshots need to be deleted.

Click onSnapshots, then delete the selected snapshots.

To create a VM template from an existing VM in Nutanix, the VM must be powered off. This ensures that the template is consistent and does not include any transient data or activity from the VM. Once the VM is powered off, the administrator can use the Prism UI to take a snapshot and designate it as a template.

A. Sysprep or Cloud-init script:These are optional for post-deployment configuration, not mandatory for creating a template.

B. The VM is powered on:This is incorrect, as the VM must be powered off.

C. Windows OS is installed:The OS type is irrelevant for creating a template.

D. The VM is powered off:Correct, as creating a template requires the VM to be in a powered-off state.

Life Cycle Management (LCM) in Nutanix is a feature designed tosimplify software and firmware upgradesacross the entire cluster. LCM automates and orchestrates upgrades for components like BIOS, hypervisors, firmware, and Nutanix software, ensuring that the cluster remains up-to-date with minimal manual intervention.

A. To optimize server performance:Incorrect, as LCM focuses on updates, not performance optimization.

B. To manage network configurations:Incorrect, as LCM is unrelated to network configuration management.

C. To simplify software and firmware upgrades:Correct, as LCM is specifically designed for this purpose.

D. To automate application deployment:Incorrect, as LCM does not handle application deployment.

The OpLog (Operational Log) in Nutanix serves as apersistent write bufferfor incoming I/O operations. It temporarily stores write requests to ensure fast acknowledgment to clients and better performance. The data is later coalesced and written to the Extent Store for long-term storage.

A. Persistent write buffer:Correct, as the OpLog optimizes write performance by buffering writes temporarily.

B. Persistent data storage:Incorrect, as this describes the Extent Store, not the OpLog.

C. Global metadata:Incorrect, as metadata operations are handled by the Metadata Store.

D. Dynamic read cache:Incorrect, as read caching is managed separately, often involving SSD-based caches.

To allow Nutanix Support to gather logs automatically without requiring manual intervention, the administrator should enablePulse. Pulse is a telemetry service that collects and sends system health, log, and usage data to Nutanix Support securely.

Steps:

Navigate toPrism Central > Settings > Pulse.

Enable the service and configure as required for your environment.

Other options:

Self-Service: Refers to role-based access for users, unrelated to log collection.

Proxy Server: Used for network communication, not log gathering.

NKP: Refers to Nutanix Cluster Protocol, unrelated to telemetry.

Nutanix Support case priority levels are defined as follows:

P1 (Critical):The system is down or severely impacted, requiring immediate attention.

P2 (High):The system is available but experiencing issues that directly impact productivity or operations.

P3 (Medium):The system is functioning, but there are non-critical issues or questions.

P4 (Low):General questions or requests that do not impact system performance.

The scenario described matchesP2, where the system is available but productivity is directly affected by the issue.

To rerun only the health checks that previously failed or issued warnings, the administrator can select theOnly Failed and Warning Checksoption in Prism Element. This targeted approach helps verify that resolved issues have been addressed without rerunning all checks unnecessarily.

Steps:

Navigate toPrism Element > Health > NCC Checks.

Filter forOnly Failed and Warning Checksand rerun them.

Other options:

A. Run LCM Pre-Upgrade: Runs pre-upgrade checks, not related to health check validation.

B. Runncc health_checks run_all: Executes all checks, not just failed ones.

C. Select Run Check for each check worked: Requires manual execution for each check.

By default, Nutanix Lifecycle Manager (LCM) auto-inventory runs at2:00 AMlocal cluster time. LCM performs a daily check to gather information about available updates for firmware, software, and other components to ensure the cluster remains up-to-date. This operation is non-disruptive and does not impact cluster performance.

In Prism Central, theImagessection within the Compute and Storage tab is used to upload ISO files, including Windows installation ISOs. Once uploaded, these images can be used to create or install VMs across clusters managed by Prism Central.

A. Catalog Items:Incorrect, as this is used to manage preconfigured application templates.

B. Templates:Incorrect, as this is used for VM templates, not ISO uploads.

C. Images:Correct, as it allows uploading and managing ISO and disk images.

D. OVAs:Incorrect, as this pertains to importing virtual appliances, not ISO files.

To run a full health check in Prism Element, the administrator should first select theActionsmenu. From there, the administrator can choose to execute health checks for the entire cluster or specific components. This ensures a comprehensive evaluation of the cluster’s health.

Other options:

Scheduled: Refers to predefined or automated health checks.

Checks: Displays the list of checks but doesn’t initiate them.

Failed: Filters checks based on their status but doesn’t start a new check.

TheData Protectionfeature in Prism Element provides built-in disaster recovery capabilities by enabling asynchronous replication between Nutanix clusters. With a latency of 30ms between the two sites, asynchronous replication can ensure that data is replicated efficiently while adhering to recovery point objectives (RPO). The administrator can configure Protection Domains and Replication Targets to set up DR between the clusters.

A. Recovery Plan:Incorrect, as Recovery Plans are part of Prism Central for orchestrated failover, not Prism Element.

B. Protection Policies:Incorrect, as these are defined under Prism Central.

C. Data Protection:Correct, as it enables disaster recovery via replication configurations in Prism Element.

D. Metro Cluster:Incorrect, as Metro Cluster requires low latency (<5ms) and is not suitable for a 30ms latency scenario.
