NEW QUESTION # 46
How many Controller VMs (CVMs) will a five-node HCI cluster have?
Answer: A
Explanation:
A conventional five-node Nutanix HCI cluster has five Controller VMs-one CVM running on each node.
AOS operates as a distributed storage and data-services system rather than relying on a single centralized storage controller. The per-node CVM architecture provides local access to the node's storage devices while cooperating with the CVMs on the other nodes to form the distributed AOS storage fabric.
The CVMs collectively provide services associated with data placement, replication, metadata, caching, compression, deduplication, snapshots, and cluster storage management. If a CVM becomes unavailable, the host can access storage services through another CVM, subject to cluster health and connectivity. The remaining CVMs also maintain the distributed cluster services required for continued operation.
The number of CVMs therefore normally matches the number of HCI nodes: three nodes produce three CVMs, four nodes produce four, and five nodes produce five. The count does not represent the replication factor or the number of simultaneously tolerated failures.
Compute-only nodes are a specific exception because they do not run a CVM. However, the question explicitly describes a five-node HCI cluster, so each node contributes storage and runs a Controller VM.

NEW QUESTION # 47
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: C
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 # 48
After deploying a VM, which tool provides additional capabilities, such as file-level restore?
Answer: A
Explanation:
Nutanix Guest Tools is a collection of guest-resident services and utilities that extends the integration between a deployed virtual machine and the Nutanix platform. One of its principal capabilities is Self-Service Restore, also described as file-level restore. When the feature is enabled and NGT is installed, an authorized VM administrator can access files from a Nutanix-protected snapshot without requiring the infrastructure administrator to restore the entire VM.
NGT establishes the guest-side functionality required to expose and use supported recovery services.
Depending on the operating system and enabled components, NGT also supports functions such as application-consistent snapshot coordination and guest communication with the Nutanix platform.
The other tools serve different lifecycle stages. Nutanix X-Ray validates platform performance, resilience and infrastructure behavior. Foundation images physical nodes and creates or expands Nutanix clusters. Nutanix Move migrates workloads from supported source environments to Nutanix AHV or other supported targets.
None of these tools supplies guest-level file recovery after normal VM deployment.

NEW QUESTION # 49
What does the Nutanix Remote Support Tunnel allow?
Answer: B
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 # 50
Which Nutanix solution provides microsegmentation and application-centric security policies for VMs?
Answer: C
Explanation:
Flow Network Security provides application-centric microsegmentation and distributed security-policy enforcement for Nutanix workloads. It uses categories and application context to define which workloads may communicate, rather than depending exclusively on static IP addresses or physical VLAN boundaries.
Policies can follow VMs as they move or scale within supported Nutanix environments.
Microsegmentation limits east-west communication between application components and reduces the potential lateral movement of malware or unauthorized users. Administrators can define policies for application tiers, environments, user groups and isolation requirements, then manage those policies centrally through Prism Central. Flow Network Security also provides traffic visualization and policy-monitoring capabilities before enforcement.
AHV supplies the virtualization and host-compute layer but is not, by itself, the security-policy product identified by the question. AOS provides distributed storage, resilience and data services. Nutanix Disaster Recovery manages workload protection, replication and recovery rather than distributed microsegmentation.
