NEW QUESTION # 111
Refer to the exhibit.
A consultant migrated multiple VMs to a new cluster. VMs were previously in VLAN 10.
Why can the VMs no longer communicate on their network?
- A. The VNIC type should be set to VMXNET2.
- B. Static IP addresses have not been assigned to the new VMs.
- C. The VLAN ID is incorrect.
- D. The GuestOS firewall is blocking traffic in the new cluster.
Answer: C
Explanation:
In scenarios where VMs have been migrated to a new cluster and they were previously on VLAN 10 but can no longer communicate, the most likely cause is that the VLAN ID setting on the virtual network interface cards (VNICs) of the VMs does not match the VLAN configuration of the new network. Ensuring that the VLAN IDs are correctly set to match the network configuration of the new cluster is essential for proper network communication.References:

NEW QUESTION # 118
Refer to the exhibit.
An administrator logged into Prism Element, notices the following in the home dashboard, and showing the exhibit.
Which action should the administrator take next?
- A. Configure the fqdn for the hosts indicated
- B. Check the hardware page for disk failures
- C. Re-run NCC specifying data_resiliency_check
- D. Troubleshoot the zookeeper server issue
Answer: A
Explanation:
The exhibit shows a screenshot of a Prism Element home dashboard with a notification that "Data Resiliency not possible" and warnings about the inability to get configured fully qualified domain names (fqdn) for hosts identified by their node numbers.
In this scenario, the administrator should take action A: Configure the fqdn for the hosts indicated. This is because the warnings on hostname resolution indicate issues with fully qualified domain names (fqdn) configuration for specific nodes. Configuring the fqdn for these hosts can help resolve these issues and improve the data resiliency of the Nutanix cluster1.

NEW QUESTION # 119
A consultant successfully completes a Foundation using a flat switch. The consultant then works with the customer to move the cluster over to their production network. After the move, the CVMs and hypervisors can no longer communicate, which prevents the cluster from starting.
Which option should be used to resolve this issue?
- A. If using VLANs, confirm the hypervisor/CVM VLAN is set as Native on the switch ports.
- B. Verify that IPv6 Link Local and DHCP is enabled on all switch ports.
- C. If the IPMI is in use, check that the IPMI can ping the default gateway over IPv6.
- D. Make sure that the IPMI and CVM VLAN is manually tagged on the Host and CVM.
Answer: A
Explanation:
The inability of CVMs and hypervisors to communicate after moving a cluster to the production network typically points to a VLAN configuration issue. The correct action is to confirm that the VLAN designated for hypervisor/CVM communication is set as the Native VLAN on the switch ports to which the nodes are connected. This setting ensures that traffic from these VLANs is properly prioritized and handled by the network, thereby restoring communication between CVMs and hypervisors and allowing the cluster to start.

NEW QUESTION # 120
An administrator recently added in 3 nodes to an existing 5 node cluster. While 1 node came with its own block, the other 2 nodes where added to an existing share. After adding the nodes, the administrator sees that the hardware tab displays the correct number of nodes, but incorrect position in the diagram tab.
What should the administrator do to resolve the issue?
- A. SSH into CVM and perform genesis restart on each CVM
- B. SSH into the CVMs and run genesis acropolis stop; cluster start
- C. Check the factory_config.json for all 3 nodes
- D. Check the factory_config. json for the two single nodes.
Answer: C
Explanation:
When nodes are added to a Nutanix cluster and there is a discrepancy in the position or configuration as shown in the hardware diagram tab, it's essential to check the factory_config.json file on all newly added nodes. This file contains important configuration details that define how each node is identified and operates within the cluster. Incorrect or inconsistent settings in the factory_config.json can lead to display and configuration errors in the Prism interface. Correcting any discrepancies in this file will help resolve issues with node identification and display in the diagram tab.

NEW QUESTION # 121
In which two ways can the IPMI address be set on a Nutanix hardware installation? (Choose two.)
- A. iLO configuration utility
- B. ipmitool
- C. BIOS configuration
- D. Nutanix Network Crashcart
Answer: B,C
Explanation:
The IPMI address on a Nutanix hardware installation can be set in two ways:
* BIOS configuration: Access the BIOS settings during boot-up to manually configure the IPMI address directly on the hardware.
* ipmitool: Use the ipmitool command-line utility to configure the IPMI address from a remote session or script, which provides a way to automate or manage IP settings without needing physical access to the BIOS.

Answer: C
NEW QUESTION # 124
What must be set to enable node discovery when using Foundation VM?
- A. Internet Access
- B. Bridged Adapter
- C. Host-only Adapter
- D. Network Address Translation
Answer: B
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.
NEW QUESTION # 125

NEW QUESTION # 127
A customer wants to validate the Microsoft SQL workload performance for a CRM application before migration to the new Nutanix cluster.
Which activity must the consultant add as part of the test plan to fulfill this requirement?
- A. Run perfmon on all CVMs.
- B. X-Ray with OLAP Workload.
- C. Run perfmon on guest VM.
- D. X-Ray with OLTP Workload.
Answer: D
Explanation:
To validate the performance of a Microsoft SQL workload for a CRM application, using X-Ray with an OLTP (Online Transaction Processing) Workload is most suitable. OLTP workloads simulate typical transactional database operations which are representative of CRM application usage, providing accurate insights into expected performance on the Nutanix platform.

NEW QUESTION # 130
Which subnet should a consultant be aware is reserved for internal connectivity within a Nutanix cluster?
- A. 192.168.5.0/26
- B. 192.168.5.0/24
- C. 192.168.5.0/23
- D. 192.168.254.0/24
Answer: B
Explanation:
The consultant should be aware that the subnet 192.168.5.0/24 is reserved for internal connectivity within a Nutanix cluster. This subnet is typically used for the internal operations of the Nutanix cluster, including CVM backplane communications. It is critical to ensure that this subnet does not overlap with any external network configurations to avoid networking conflicts that can affect cluster operations and communications.
