NEW QUESTION # 12
When creating a new VLAN, what should be specified as the VLAN ID if a network interface uses the Native VLAN?
Answer: D
Explanation:
In Nutanix AHV network configuration, VLAN ID 0 represents the native or untagged VLAN. Therefore, when a VM network interface must communicate through the native VLAN on the connected physical-switch port, the administrator specifies VLAN ID 0 while creating the VLAN-backed virtual network.
The native VLAN carries Ethernet frames without a conventional 802.1Q VLAN tag across the applicable switch connection. Nutanix uses the value 0 as the administrative representation for this untagged behavior. It does not mean that an ordinary production VLAN numbered zero is being created on the physical switch. The physical switch port and AHV uplink configuration must still agree on which traffic is treated as native or untagged.
VLAN ID 1 is commonly a switch default but is not Nutanix's required value for designating native-VLAN behavior. VLAN 255 is an otherwise ordinary numerical VLAN identifier and has no special native-VLAN meaning. VLAN 4096 is outside the usable IEEE 802.1Q VLAN range; Nutanix accepts VLAN identifiers through 4094 for normal tagged VLAN configurations.

NEW QUESTION # 13
An administrator needs to take an immediate snapshot of a single VM.
How should the administrator complete this task?
Answer: D
Explanation:
A manual, immediate snapshot of an individual VM is created from the VM dashboard in Prism Element. The administrator opens the VM table, selects the target VM and invokes the Take Snapshot action. Prism then creates a point-in-time snapshot containing the VM configuration and the supported virtual-disk state.
This procedure is appropriate when the requirement concerns one VM and the snapshot must be taken immediately. Prism Central Data Protection is used for broader protection policies, recovery points, protection schedules and multi-cluster disaster-recovery operations. Those capabilities are valuable for recurring or policy-based protection but are not the direct manual workflow described in the question.
Connecting to a Controller VM is unnecessary and would bypass the supported administrative interface. The Prism Central Images service manages deployable disk images, ISO files and VM image resources; an image is not a point-in-time snapshot of a running VM.
For application-consistent protection, additional guest-side preparation such as Nutanix Guest Tools may be required. A standard manual snapshot, however, is initiated through the selected VM's Prism Element actions.

NEW QUESTION # 14
An administrator is provisioning a new Linux virtual machine.
Which timezone is recommended for this VM?
Answer: B
Explanation:
UTC is the recommended timezone selection when creating a Linux VM on AHV. Nutanix specifically states that the real-time clock of a Linux VM must operate in UTC. Selecting the UTC timezone ensures that the guest's hardware-clock interpretation is consistent with Linux conventions and avoids time shifts caused by local timezone or daylight-saving changes.
Time consistency is essential for authentication, application logging, distributed databases, monitoring, certificate validation and event correlation. The guest operating system can still display a regional timezone to users at the application or operating-system level while maintaining its underlying hardware clock in UTC.
"Local" can cause the guest to interpret the virtual hardware clock according to a regional offset, producing incorrect timestamps after migration, reboot or daylight-saving transitions. "Cluster" is not a supported timezone designation for this VM setting. RTC means real-time clock and describes the clock mechanism rather than a selectable geographic timezone.
The VM should also use a reliable NTP source after deployment so its operating-system time remains synchronized.

NEW QUESTION # 15
A VM is experiencing delays even though its own CPU usage appears low.
Which metric should be checked to identify scheduling issues?
Answer: B
Explanation:
CPU Ready measures the time during which a virtual CPU is prepared to execute but is waiting for the hypervisor to schedule it on a physical processor. A VM can therefore report low apparent CPU consumption while still responding slowly: its workload is not continuously executing because the assigned vCPUs are waiting for physical CPU time.
Elevated CPU Ready commonly indicates physical CPU contention, excessive vCPU allocation, an unfavorable vCPU-to-core ratio, or competition from other VMs on the host. The administrator should correlate CPU Ready with host CPU utilization, VM sizing, the number of runnable vCPUs, and workload behavior. Assigning additional vCPUs without confirming the cause can worsen scheduling delays because the hypervisor may need to coordinate more virtual processors.
Disk capacity measures available storage space and does not identify processor scheduling latency. Memory usage can reveal pressure, swapping, or insufficient guest memory, but it does not directly represent time spent waiting for CPU scheduling. Snapshot size relates to retained point-in-time storage data and is unrelated to hypervisor CPU dispatch. Nutanix identifies CPU Ready Time as the percentage of CPU wait time, making it the appropriate metric. Reference: Nutanix Intelligent Operations - VM Details and CPU Ready Time .

NEW QUESTION # 16
What is the purpose of Traffic Mirroring on AHV hosts?
Answer: C
Explanation:
Traffic Mirroring replicates selected network traffic from AHV interfaces or source ports and delivers the copied traffic to a designated virtual NIC on a guest VM. The destination VM normally runs monitoring, packet-capture, intrusion-detection, or network-analysis software. This permits inspection of traffic without placing the monitoring system directly within the source workload's forwarding path.
The destination receives copies of packets; it does not become the router or default gateway for the source traffic. Production traffic continues through its normal forwarding path, while the mirrored copy is supplied to the monitoring vNIC. Administrators must select the correct source interfaces, destination VM, direction, and placement configuration so that the monitoring system receives the intended traffic.
LACP performs physical uplink aggregation and link negotiation, which is unrelated to packet replication.
DHCP-based IP assignment is an IP address-management function. Routing overlay traffic through a VPC gateway belongs to Flow Virtual Networking and virtual private cloud routing, not AHV traffic mirroring.
The language in option B corresponds directly to the official function: traffic is mirrored from AHV host interfaces to a guest VM's vNIC. This is conceptually comparable to a switch-port analyzer capability implemented within AHV networking.
