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.

Fordark site clusters, theNutanix Compatibility Bundlemust be downloaded prior to running LCM Inventory or updates. This bundle contains the necessary metadata and software binaries to perform inventory collection and upgrades in environments without internet connectivity.

A. Nutanix Foundation:Incorrect, as Foundation is used for initial deployments, not for LCM updates.

B. Nutanix Compatibility Bundle:Correct, as it contains the necessary files for offline LCM operations.

C. Nutanix Prism Central:Incorrect, as this does not pertain to offline updates.

D. Nutanix Foundation Platform:Incorrect, as this is not required for LCM Inventory or updates.

Redundancy Factor 3 (RF3) requires a minimum of five nodes in the cluster to ensure that data can be distributed across enough nodes to tolerate the failure of two nodes. If the cluster has fewer than five nodes, RF3 cannot be enabled.

A. Check that the cluster has been properly licensed:Licensing is not directly related to enabling RF3.

B. Check that the cluster has five or more nodes:Correct, as RF3 requires at least five nodes.

C. Check hardware availability of the nodes:While hardware health is important, it does not determine RF3 eligibility.

D. Check AOS version and upgrade, if needed:RF3 requirements are not specific to an AOS version.

In aRedundancy Factor 3 (RF3)cluster,5 copies of the metadataare maintained to ensure data durability and cluster resiliency. RF3 provides fault tolerance against up to two simultaneous failures (e.g., node or disk failures) and requires more metadata copies to achieve this level of protection.

Other redundancy factors:

RF2maintains 3 copies of metadata.

RF3 requires at least 5 metadata copies to protect against additional failures.

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.

When configuring dual encryption in Nutanix, anExternal Key Manager(EKM) is required. This allows the cluster to use an external hardware-based or software-based key management system to securely store and manage encryption keys. The combination of external and native encryption ensures compliance with high security standards.

A. Trusted Platform Module:Incorrect, as TPM is not used for managing dual encryption keys.

B. External Key Manager:Correct, as dual encryption relies on an external system to manage keys.

C. Native Key Manager:Incorrect, as native key management alone does not support dual encryption.

D. Lockdown Mode Enabled:Incorrect, as Lockdown Mode relates to cluster security, not encryption key management.

Nutanix Cloud Clusters (NC2)enables extending on-premises datacenters into public cloud environments, such as AWS or Azure. This solution allows administrators to seamlessly migrate workloads, scale operations, and manage resources across hybrid cloud environments using a unified control plane.

A. Nutanix Cloud Security:Incorrect, as this focuses on securing workloads in the cloud, not extending datacenters.

B. Nutanix Cloud Clusters:Correct, as NC2 enables hybrid cloud functionality by extending on-prem clusters into the public cloud.

C. Nutanix Kubernetes Engine:Incorrect, as this is used for container orchestration, not hybrid cloud extension.

D. Nutanix Data Services:Incorrect, as this refers to storage and data management capabilities.

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.

The correct answer isB. Internal NTP sources.

Nutanix strongly recommends configuringreliable internal NTP sources(e.g., enterprise-managed NTP servers or domain NTP servers) to ensure:

Time consistency across all nodes and CVMs

Accurate logging, monitoring, authentication (e.g., Kerberos), and cluster operations

Avoiding dependency onexternal/public NTPsources, which may berate-limited, unavailable, or blockedby firewalls

Clarifications:

A (Windows time sources):Generally discouraged unless they are configured to use a stratum 1/2 reliable upstream source.

C (Rate-limited sources):Not recommended; can result in dropped or inconsistent time updates.

D (External ISP NTP):Not preferred for production clusters due to reliability concerns.

Excerpt: “Use reliable and consistent internal NTP servers for all Nutanix clusters to maintain time synchronization.”

Answer: B

The correct answer isA. br0.

InAHV (Acropolis Hypervisor),br0is thedefault native Linux bridgecreated on each hypervisor host. It is used for VM traffic and external communication. AHV leveragesOpen vSwitch (OVS)to manage virtual networking, but the bridge is exposed as br0 in the host's network configuration.

Key points:

br0connects VM virtual NICs (vNICs) to the physical network via the host's uplinks.

It is pre-configured during Foundation or cluster deployment.

virbr0is typical in KVM environments but isnot usedin AHV.

Official Reference:

Nutanix AHV Networking Guide

Nutanix KB #2027 – AHV Host Networking

Excerpt: “AHV uses br0 as the default bridge on the host, configured by Open vSwitch for guest VM networking.”
