From a hypervisor, which IP address should the consultant use to connect to the locally tossed on?
A. 192.168.5.254
B. 172.16.19.2
C. 10.100.5.5
D. 192.168.1.254
Explanation: When configuring network settings for a hypervisor or accessing local services hosted on it, the IP address must be reachable from the network configuration you are currently using. Given the generic nature of the options, the correct choice typically depends on the subnet used for management purposes, which often uses a standard private address. "192.168.5.254" is a common choice for local network configurations and is likely set up as the gateway or a primary network interface on the hypervisor.
A consultant configures an ESXi cluster which will utilize a vSphere Distributed Switch (vDS). The consultant has just migrated the first host to the dvSwitch when several alerts appear within Prism Element regarding Host-to-CVM connectivity. What is causing these alerts?
A. The consultant migrated the CVM Backplane and VM network adapter over to the vDS.
B. The consultant migrated the CVM svm-iscsi-pg network adapter over to the vDS.
C. The consultant migrated the CVM Backplane network adapter over to the vDS.
D. VLAN tags are incorrectly configured on the vDS port groups.
Explanation: When migrating an ESXi host to a vSphere Distributed Switch (vDS), it's crucial to correctly configure network adapters, including those for the Controller Virtual Machine (CVM). If the consultant migrated both the CVM backplane and the VM network adapter to the vDS, this could disrupt host-to-CVM connectivity if not configured correctly on the vDS. Such a setup requires precise configuration of network settings and VLAN tags to maintain seamless connectivity and avoid communication alerts in Prism Element.
An administrator needs to forecast infrastructure requirements for a new program and its associated applications. Prior to the projected start of the new program, all existing applications will be decommissioned. How should the administrator perform this task?
A. Check the Disregard Existing Workloads radio button in the Runway scenario.
B. Check the Disregard Existing Nodes radio button in the Runway scenario.
C. Add up the recovered workloads and manually remove from the Runway configuration.
D. Power down the workloads during a maintenance window and run the Capacity Runway.
An administrator has a custom backup application that requires a 2TB disk and runs in Windows. Throughput is considerably lower than expected.
The application was installed on a VM with the following configuration:
• Four vCPUs with one core/vCPU
• 4GB of Memory
• One 50GB vDisk for the Windows installation
• One 2TB vDisk for the application
What is the recommended configuration change to improve throughput?
A. Increase the number of cores per vCPU
B. Increase the vCPUs assigned to the VM
C. Span the 2TB disk across four vDisks
D. Add 4GB of memory to the VM
A consultant creates a new cluster using ESXi as the hypervisor. After creating the cluster, the consultant begins to run Life Cycle Manager (LCM) updates. During the LCM upgrade pre-checks, an error is returned. Which configuration is causing this issue?
A. ESXi cluster admission control is disabled.
B. ESXi cluster DRS is enabled.
C. ESXi cluster HA is enabled.
D. ESXi cluster admission control is enabled.
Explanation: The error during LCM pre-checks in an ESXi-based Nutanix cluster with HA enabled is most likely due to the ESXi cluster admission control being enabled. Admission control is a feature in VMware ESXi that reserves resources for HA purposes to ensure that sufficient resources are available in the event of host failures. When admission control is enabled, it can interfere with Nutanix LCM operations, which may require resource reallocation or reconfiguration that conflicts with the reserved capacities set by admission control. Disabling admission control during LCM updates would typically resolve this issue.References: VMware documentation on HA and Admission Control, Nutanix LCM documentation.
An organization is planning an upgrade to AOS 5.15 and wants to understand which cluster products and/or services are supported for physical traffic isolation.
Which Nutanix component supports its network traffic being isolated onto its own virtual network?
A. Volumes
B. Objects
C. Containers
D. Files
A consultant is onsite and needs to start their Foundation Virtual Machine (FVM) to image Nutanix hardware. The FVM fails to boot. The consultant decides to use a different Foundation method. Assuming the nodes will discover, which Foundation type or configuration option should the consultant select?
A. Foundation VM
B. Use IPMI IPs
C. Use IPMI MACs
D. Foundation Applet
Explanation: If the Foundation VM fails to boot and other methods need to be considered, the best alternative is the Foundation Applet. This lightweight tool runs on a laptop or other device and doesn't require booting a VM, providing a straightforward method to image Nutanix hardware, particularly useful in situations where hardware constraints or other issues prevent the use of a full Foundation VM.
What must be set to enable node discovery when using Foundation VM?
A. Host-only Adapter
B. Bridged Adapter
C. Network Address Translation
D. Internet Access
Explanation: For enabling node discovery when using the Foundation VM, the network adapter of the Foundation VM must be set to a Bridged Adapter. This configuration allows the VM to appear as a separate device on the same physical network as the host machine, making it possible for the Foundation VM to communicate directly with the nodes that are also connected to the same network. This is essential for node discovery and subsequent imaging operations performed by the Foundation tool. References: Nutanix Foundation Guide, Nutanix Networking Best Practices.
A consultant is completing final network failover testing on a recently deployed AHV cluster.
The cluster consists of the following:
•Three nodes
•Two uplinks connected to two switches
•Supported SFPs
The consultant removed one SFP+ out of each node. Two of the nodes (Hostl I Host2) failed over to the backup NIC correctly without any interruption but have lost communication with the third node (Host 3) hypervisor/CVM. Inserting the original SFP+ back into the problematic node allowed the network to be connected and the two healthy nodes could communicate successfully again.

Bond: brO-up

What should the consultant validate first?
A. Validate NIC card on node is seated properly.
B. Validate that the correct interfaces are included in the bridge.
C. Validate the customer has configured all their switch ports identically.
D. Validate the SFP+ is fully plugged into the node and switch.
An administrator needs to replace an aging SAN and move to a hyper-converged infrastructure. The existing environment consists of the following hosts that are connected to the SAN:
• 5xAIX hosts
• 3x Hyper-V hosts
• 9xESXi hosts
• 2x physical SQL Clusters (Windows Server 2012R2 hosts)
After deploying a Nutanix AHV cluster, which two actions should the administrator take to meet the requirements? (Choose two.)
A. Deploy Volumes to support the AIX and SQL workloads.
B. Migrate the ESXI workloads to AHV using Move.
C. Deploy Files to support the AIX hosts.
D. Migrate the ESXi and Hyper-V workloads using Move.
An administrator receives reports about a Nutanix environment. The investigation finds the following;
• VMs are experiencing very high latency
• Each node is equipped with a single SSD, utilized at 95%
• Each node is equipped with three HDDs, utilized at 40%
Why are the guest VMs experiencing high latency?
A. CVMs are overwhelmed by disk balancing operations.
B. All VM write operations are going to HDD.
C. All VM read operations are coming from HDD.
D. VMs are unable to perform write operations.
An administrator receives an error indicating that the CVMs in the cluster are not syncing to any NTP servers. An investigation of the issue finds: • The NTP servers are configured in Prism • The time on all CVMs is the same • Both the CVMs and AHV hosts are configured for the UTC time zone Which two steps can be taken to troubleshoot this issue? (Choose two.)
A. Confirm that the NTP servers are reachable from the CVMs.
B. Restart genesis on all CVMs.
C. On a CVM. run the command a Hash ntpq -pn.
D. Restart the chronos service on all CVMs.
