NEW QUESTION # 90
Which bond type provides the best utilization of multiple physical NICs for VM traffic throughput?
Answer: D
Explanation:
Balance-tcp provides active-active link utilization through Link Aggregation Control Protocol and is the strongest choice when the objective is to maximize aggregate VM traffic throughput across multiple physical NICs. The mode distributes traffic using flow information, allowing separate TCP flows-including flows originating from the same VM-to use different physical uplinks. This can increase host and VM bandwidth utilization beyond the capacity of a single uplink when sufficient parallel traffic flows exist.
Balance-tcp requires the corresponding physical-switch ports to be configured as a compatible LACP link aggregation group. The AHV bond and upstream switch configuration must agree; otherwise, connectivity or traffic-distribution failures can occur.
Active-Backup uses only one uplink for forwarding while the other remains available for failover, providing redundancy but not simultaneous bandwidth utilization. Balance-slb is also an active-active mode and does not require switch-side LACP, but its source-load-balancing behavior generally associates traffic sources with particular uplinks and cannot distribute an individual flow across links. "No Uplink Bond" supplies neither link aggregation nor bond-level redundancy.

NEW QUESTION # 91
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: B
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.

What TCP port is required to access the Prism Element GUI and view cluster information?
Answer: A
NEW QUESTION # 93
During cluster expansion, what network requirement must be met for the automatic discovery of new, unassigned factory-prepared nodes to succeed?
Answer: D
Explanation:
Automatic discovery during cluster expansion depends on IPv6 multicast communication between the existing environment and the unassigned factory-prepared nodes. The physical switch must therefore allow the relevant IPv6 multicast packets to traverse the Layer 2 network used for discovery.
Factory-prepared nodes initially use IPv6 link-local addressing and multicast-based discovery so that Prism can locate them before final production addresses and cluster membership are assigned. If IPv6 is disabled on the applicable switch ports, filtered by the network or otherwise unable to pass between the nodes, automatic discovery fails. The administrator may then need to correct the network configuration or use an available manual-discovery procedure.
The requirement is not limited to AHV clusters; supported cluster-expansion workflows also exist for other Nutanix-supported hypervisors. IPv4 multicast is not the specified discovery mechanism. Pre-assigning static production IP addresses is also not required for discovering eligible factory-prepared nodes and may conflict with the intended preparation state.

NEW QUESTION # 94
What is the purpose of Traffic Mirroring on AHV hosts?
Answer: A
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.
