NEW QUESTION # 67
What does the Nutanix Remote Support Tunnel allow?
Answer: C
Explanation:
The Remote Support Tunnel establishes a controlled remote connection through which authorized Nutanix Support personnel can access a cluster and assist with diagnosis and troubleshooting. The customer retains control over whether the tunnel is enabled, and it can be opened for a defined period rather than operating as an unrestricted permanent connection. Nutanix documentation describes the feature as a remote support connection and allows administrators to start the tunnel for a limited duration.
The tunnel is part of the support workflow rather than a workload data service. Moving applications from an on-premises environment to a public cloud is handled through migration products and hybrid-cloud mobility capabilities such as Nutanix Move or Nutanix Cloud Clusters workflows. Replication between sites is provided through protection policies, protection domains, recovery plans, or other disaster-recovery services.
Encryption or isolation between guest VMs is addressed through virtual networking, security policies, and microsegmentation-not the support tunnel.
The decisive distinction is the tunnel's administrative purpose: it gives Nutanix technical support temporary connectivity to investigate cluster problems. Reference: Prism 7.5 - Remote Support Connections . NHCF alignment: leveraging Nutanix support functions and troubleshooting services.
NEW QUESTION # 68
An administrator needs to ensure that business-critical VMs maintain normal CPU performance.
Which action can the administrator take to generate alerts when VMs are oversubscribed during peak hours?
Answer: B
Explanation:
CPU Ready Time measures the percentage of time that a VM's virtual CPUs are ready to execute but cannot be scheduled on physical CPU resources. It is therefore a direct indicator of processor contention or CPU oversubscription. A VM can show moderate CPU utilization while still suffering poor response times because its vCPUs are waiting for execution time.
Prism Central supports user-defined alert policies based on infrastructure metrics, including VM CPU Ready Time. The administrator can define a threshold and evaluation period so that an alert is generated when scheduling delays exceed an acceptable level during peak demand. This produces proactive notification instead of requiring periodic manual review.
Pulse sends diagnostic information to Nutanix Support but does not create the workload-specific threshold requested. Increasing vCPU allocation without first validating contention may worsen CPU Ready Time because the hypervisor must schedule additional virtual processors. Reviewing average CPU usage is retrospective and does not automatically generate an alert. The most precise control is therefore a custom CPU Ready alert.

NEW QUESTION # 69
Which task must be performed first when preparing to upgrade an Internet-connected Nutanix cluster using Life Cycle Manager?
Answer: D
Explanation:
The administrator must first run an LCM inventory. Inventory establishes the cluster's current software and firmware state, refreshes component metadata, and obtains information about compatible updates available through the connected Nutanix source. LCM requires this baseline before it can accurately identify upgrade candidates and construct a valid update plan.
Executing an upgrade immediately is premature because LCM must first know which component versions are installed and which update combinations are supported. The upgrade workflow subsequently performs dependency evaluation and prechecks before applying selected components. Directly uploading software bundles is principally associated with dark-site or disconnected workflows. An Internet-connected cluster can retrieve the required metadata and available bundles through its configured online source. Restarting cluster services is neither the initial preparation step nor a normal manual prerequisite for LCM discovery.
Inventory also refreshes the LCM framework when required and makes the resulting component information available in the management interface. After inventory completes, the administrator reviews available updates, selects applicable components, executes prechecks, resolves reported issues, and then initiates the upgrade plan. This sequence minimizes compatibility and dependency risks.

NEW QUESTION # 70
An administrator runs a cluster health check and notices that a specific plugin returns a WARN status.
How should the administrator interpret this status?
Answer: C
Explanation:
An NCC WARN status means the health-check plugin returned an unexpected value that requires administrator investigation. Nutanix states that a warning requires user intervention and should be resolved as soon as reasonably possible. A warning is significant, but it is distinct from an NCC failure indicating that the tested aspect is currently unhealthy.
The answer choices deliberately correspond to different NCC result classifications. Option A describes an execution error: the plugin did not run successfully and therefore cannot establish a valid PASS, INFO, WARN, or FAIL result. Option B describes a FAIL condition, where the tested cluster component or state is unhealthy and can require immediate corrective action. Option D describes INFO, in which the plugin returns an expected informational value that cannot be classified as a straightforward pass or failure.
Administrators should read the complete warning output because it normally identifies the affected check, entity, observed value, expected condition, and recommended remediation. The warning should then be correlated with Prism alerts, recent changes, and other NCC results. It must not be ignored merely because the cluster remains operational.

NEW QUESTION # 71
A junior administrator has been tasked with cloning a Virtual Machine (VM) and has asked the senior administrator what the default state of Nutanix Guest Tools (NGT) is.
Which answer should the senior administrator respond with?
Answer: D
Explanation:
Nutanix Guest Tools is disabled by default on a cloned VM, even when NGT was installed and enabled on the source VM. Cloning reproduces the VM configuration and virtual disks, but the clone becomes an independent machine with its own identity. Automatically retaining the source VM's active NGT configuration could produce duplicate guest-agent identities or invalid communication relationships with the Nutanix cluster.
The administrator must explicitly enable NGT on the cloned VM and complete the appropriate guest-side procedure. If the clone is powered off, NGT can be enabled through Prism and the VM can then be powered on. If it is already running, the administrator enables NGT and may need to restart the Nutanix Guest Agent or remount and execute the installer, depending on the guest operating system and existing NGT state.
"Deleted" is inaccurate because the cloned virtual disks may still contain the NGT software inherited from the source. The management state is disabled, not necessarily absent. "Updated" is also incorrect because cloning does not automatically upgrade the installed NGT package. Administrators should verify the resulting NGT status and version before relying on application-consistent snapshots or guest operations.
