Which update in LCM can an administrator apply on a per-node basis?
Answer : B
BMC (Baseboard Management Controller) updates can be applied per-node in Nutanix LCM, unlike AOS or AHV, which require cluster-wide upgrades.
Option B (BMC) is correct:
BMC firmware controls remote management and power cycling of individual nodes.
Updating BMC does not impact the entire cluster and can be done per node.
Option A (AOS) is incorrect:
AOS upgrades affect the entire cluster and require cluster-wide consistency.
Option C (NCC) is incorrect:
NCC updates apply across all nodes simultaneously, ensuring uniformity in checks.
Option D (AHV) is incorrect:
AHV updates require coordinated upgrades across hosts to maintain VM availability.

A security team asks an administrator to set up port mirroring of a specific source VM to a target VM.
What must the administrator ensure for this configuration to be possible?
Answer : B
Port mirroring requires the source and target VMs to be on the same host to efficiently copy network traffic without additional routing overhead.
Option B (Source VM and Target VM are on the same host) is correct:
AHV's port mirroring only works within a single host because network packets are intercepted before leaving the hypervisor.
If the VMs are on different hosts, mirroring cannot be configured without additional network tools.
Option A (Same VLAN) is incorrect:
VLAN membership is not a requirement for port mirroring.
Option C (Same subnet) is incorrect:
Port mirroring happens at the virtual switch level, which does not require VMs to be in the same subnet.
Option D (Same VPC) is incorrect:
While VPCs provide network isolation, they do not control port mirroring availability.

How can an administrator create a custom Intelligent Operations report, and run across multiple Prism Central instances?
Answer : C
In a five-node cluster, an administrator noticed that three VMs are consuming too many resources on a single host.
Acropolis Dynamic Scheduling (ADS) is not able to migrate these VMs.
What is the most likely reason preventing ADS from migrating these VMs?
Answer : B
VMs using GPU pass-through cannot be live-migrated because they are directly tied to a physical GPU on a specific host.
Option B (VMs use GPU pass-through) is correct:
Pass-through devices (such as GPUs) are directly assigned to VMs, making migration impossible unless the VM is powered off first.
Option A (VMs use a Volume Group) is incorrect:
Volume Groups support live migration unless they are configured incorrectly.
Option C (VM-VM anti-affinity) is incorrect:
Anti-affinity rules prevent two specific VMs from running together, but do not prevent migration.
Option D (VMs use external NAS) is incorrect:
Using NAS does not block VM migration, as Nutanix supports shared storage across hosts.

An administrator needs to enable Windows Defender Credential Guard to comply with company policy.
The new VM configurations include:
Legacy BIOS
4 vCPUs
8 GB RAM
Windows Server 2019
What must be changed in order to properly enable Windows Defender Credential Guard?
Answer : B
Windows Defender Credential Guard requires UEFI firmware and Secure Boot to function properly.
Option B (Enable UEFI with Secure Boot) is correct:
Credential Guard requires a UEFI-based boot mode rather than Legacy BIOS.
Secure Boot ensures only trusted OS components load, reducing attack surface for credential theft.
Option A (Update vCPU to 8) is incorrect:
Increasing vCPUs does not impact Credential Guard compatibility.
Option C (Use Windows Server 2022) is incorrect:
Windows Server 2019 supports Credential Guard; upgrading to 2022 is not required.
Option D (Update Memory to 16GB) is incorrect:
Credential Guard has no minimum RAM requirement beyond general OS needs.

What guest customization options are available when creating a VM template?
Answer : A
Guest customization options allow administrators to automate OS configuration during VM deployment from a template.
Option A (Sysprep, Cloud-init, Custom Script, Guided Script) is correct:
Sysprep (for Windows) and Cloud-init (for Linux) enable custom OS configurations.
Custom Scripts can be used for advanced automation.
Options B and C are incorrect:
Bash, Powershell, Python, and YAML can be used in automation, but they are not guest customization options in VM templates.
Option D is incorrect:
Guest customization is fully supported in Nutanix templates.

An administrator has been tasked with monitoring performance across a number of different entities in the Nutanix cluster. The CIO has asked the administrator to provide Analysis charts that show performance as granularly as possible.
Given this request, what is the smallest preset time interval (in hours) that the administrator can select in a Metric or Entity Chart?
Answer : A
