APriority 1 (P1)case guarantees an8-hour response timefor customers with Production Support. P1 cases are designated for critical issues that severely impact business operations orcause a complete system outage, requiring immediate attention from Nutanix Support.Other priorities:

P2: High-impact issues but not critical, response time varies.

P3: Medium impact, typically non-urgent issues.

P4: Low priority, general inquiries or minor issues.

To verify if the cluster is currently protected from potential data loss due to a component failure, the administrator should check theData Resiliency Status widgeton the Prism Element Home dashboard. This widget provides real-time information about the cluster's resiliency status, including warnings or errors about data redundancy or protection.

Other options:

A. Select the gear icon and then select Pulse:Pulse is used for telemetry data, not data resiliency status.

B. Click on Home and then Alerts:Alerts show specific issues but do not directly indicate the overall resiliency status.

D. Navigate to the Health dashboard:The Health dashboard provides detailed health checks but does not display the current resiliency status.

When using ESXi as the hypervisor in a Nutanix cluster, the supported storage protocol for a datastore isNFS (Network File System). Nutanix exposes its distributed storage to ESXi hosts using NFS for VM storage. This protocol is simple to configure and provides high performance and reliability through Nutanix’s data services.

Other options:

iSCSI: Not typically used for ESXi datastores but can be utilized for specific use cases like external storage connectivity.

SMB: Not supported for ESXi datastores.

LVM: Logical Volume Management is not used in this context.

The Controller VM (CVM) uses thevs0bridge by default to communicate with the AHV host it runs on. Thevs0bridge is a virtual switch configured on the AHV host, providing connectivity between the CVM, virtual machines, and external networks. This setup ensures efficient network communication within the Nutanix cluster.

Other options:

virbro: Typically used in standalone KVM configurations, not in Nutanix AHV.

broandbridge0: Incorrect references to Nutanix networking structures.

For a cluster withRedundancy Factor 2 (RF2), at least4 nodesare required to configure Erasure Coding. Erasure Coding (EC) distributes data and parity across nodes to improve storage efficiency while maintaining data protection. RF2 requires a minimum of 4 nodes to ensure sufficient space for data and parity distribution.

Other options:

3 nodes: Insufficient for EC with RF2.

5 and 6 nodes: Can support EC, but the minimum requirement is 4.

TheRecycle Binin Nutanix clusters temporarily stores deleted VMs for 24 hours, allowing administrators to recover them if needed. This feature helps protect against accidental deletions by providing a grace period for recovery before permanent deletion occurs.

A. Stores the OpLog's most recent deleted data in case of a CVM failure:Incorrect, as the OpLog pertains to write operations, not VM deletion.

B. Keeps deleted VMs for 24 hours for recovery:Correct, as the Recycle Bin's purpose is temporary VM recovery.

C. Allows administrators to undo the last five actions:Incorrect, as there is no such feature for undoing multiple actions in Prism.

D. Centralizes the deleted data from the different VMs in the cluster:Incorrect, as the Recycle Bin is specifically for deleted VMs, not generalized data centralization.

The default admin session logout time in Nutanix is15 minutes. If no activity is detected within this time, the session is automatically logged out for security reasons. This timeout can be adjusted in the system settings if needed, depending on organizational requirements.

Non-migratable VMs in a Nutanix cluster typically include those with attached Volume Groups. This is because such VMs leverage direct-attached storage via iSCSI, which ties them to a specific host, preventing live migration to another host. Volume Groups provide block storage to applications, and the iSCSI protocol does not support live migration of such connections.

Here's a breakdown of the options:

A. VMs without NGT:Nutanix Guest Tools (NGT) are used for guest-level integration but do not affect VM migratability.

B. VMs marked as an Agent:This setting does not inherently make VMs non-migratable. It primarily affects roles and tasks within certain configurations.

C. Memory Overcommitted:While memory overcommitment can affect performance, it does not make VMs non-migratable. Nutanix AHV handles memory allocation dynamically.

D. VMs with attached Volume Groups:Correct answer, as the iSCSI connections used by Volume Groups are host-specific and cannot migrate seamlessly.

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.

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.

Nutanix AHV (Acropolis Hypervisor) supports integrated IP address management (IPAM) as a built-in feature. IPAM allows administrators to dynamically allocate and manage IP addresses for VMs within a network segment. This functionality simplifies network management by automating the assignment of IPs without relying on external DHCP servers.

A. ESXi:Incorrect, as ESXi does not include built-in IPAM.

B. Hyper-V:Incorrect, as Hyper-V lacks integrated IPAM functionality.

C. AHV:Correct, as AHV has built-in IPAM for automated IP address allocation.

D. XenServer:Incorrect, as XenServer does not support integrated IPAM.

Log files requested by Nutanix Support can be collected from theSettingsdashboard in Prism Element. Within Settings, administrators can access the "Export Logs" or "Support" section to collect and upload diagnostic data directly to Nutanix Support.

A. Settings:Correct, as logs are collected and uploaded via the Settings dashboard.

B. Alerts:Incorrect, as Alerts display system issues but do not provide log collection options.

C. Health:Incorrect, as the Health dashboard focuses on system checks and cluster status.

D. Analysis:Incorrect, as the Analysis dashboard provides performance monitoring, not log collection.
