Which step should the consultant take next?

4. A consultant deploys a four-node VMware ESXi cluster and vCenter server. An HA/DRS cluster is configured for all four nodes. The customer deploys five new VMs on the cluster.

During the knowledge Transfer, a network cable on one node is removed to demonstrate HA and migration of the VMs to another host. In the HA/DRS cluster settings, the VM Restart Priority for all CVMs is set to Disabled. The customer observes warnings that the CVM on the ejected host is no longer powered on.

Which ESXi HA/DRS cluster setting is missing?

5. 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?

6. A customer has engaged a Nutanix consultant to deploy a cluster consisting of two NX-3460-G6 blocks.

The consultant arrives at the customer site and fines the following:

* One rack with a total of 5U available

* Two ToR switches with 14 total available ports

* Dual PDUs with six available sockets

What will prevent the consultant from successfully installing the cluster?

7. During a six-node cluster deployment, one node fails to image successfully and Foundation is unable to automatically configure the cluster. The consultant decides to manually complete cluster formation with the successful nodes, then expand the cluster with the remaining unconfigured node.

Which command should be used to begin the process?

8. A consultant is setting up a new Hyper-V cluster.

The customer requirements are as follows:

* VMs should automatically failover to another host if the host crashes

* Host CPU and Memory resources should be evenly balanced

* New VMs should be placed on the host with the most resources available

Which two Hyper-V features can be used to meet the requirements? (Choose two.)

9. A consultant is setting up a new vSphere cluster. Customer requirements are as follows:

* VMs should automatically failover to another host if the host crashes

* Host CPU and Memory resources should be evenly balanced

* New VMs should be placed on the host with the most resources available.

Which two settings should be turned on to meet the requirements? (Choose two.)

10. Asystems administrator needs to add more VMs to their Nutanix cluster.

Which two actions should the administrator perform to determine if the current cluster can accommodate the new VMs? (Choose two.)

11. HOTSPOT

A system administrator needs to shut down an AHV node in a Nutanix cluster without causing service disruption. The administrator checks data resiliency and verifies that the cluster can tolerate a node down.

Which three steps should the administrator perform next? (Choose three.)

12. An administrator needs to replace the self-signed certificate on a cluster .

Which two requirements must be met as part of the process? (Choose two.)

13. An organization subscribes to field advisories from the Nutanix support portal. An administrator receives an email about a rare problem that could cause cluster instability and affect the entire AOS cluster. The organization is running Vmware vsphere 6.x on Nutanix.

What action should be taken to resolve this issue?

14. A consultant needs to review a customer’s switch port configuration to identify any issues.

Other customer requirements are as follows:

* Leverage LACP

* Native VLAN will not be used

* Use Multiple Upstream switches

* Use VLANs 20-25 and 30

* LACP Fallback has been Enabled

* vPC or MLAG has been configured

What must be included in a configuration in order to meet these requirements?

15. An alert about RX errors on eth2 on a node is reported in the cluster. The administrator logs in to the CVM in question, checks the ping_* files in the data/logs/syststats folder, and notices intermittent ping loss.

The node in question has the following network configuration:





Which action should be used to troubleshoot without disrupting the VMs running on this node?

16. A consultant is running Foundation. The cluster creation fails during the process. The host logs confirm that the nodes have been successfully imaged. The consultant decides to create the cluster manually.

Which command should the consultant use?

17. Which subnet is reserved for internal connectivity within a Nutanix Cluster?

18. An administrator is monitoring the Nutanix v5.15-based AOS cluster performance logs and notices that a SQL server VM is greatly exceeding its intended maximum IOPS. The administrator has confirmed that a QoS policy was previously created for the group of VMs this server is a member of.

What are two reasons that this VM would exceed its maximum configured IOPS from the QoS Policy? (Choose two.)

19. Refer to the exhibit.





An administrator is commissioning a Nutanix Enterprise Cloud. Once the user VMs have been deployed and are running, the administrator finds that VMs on the same host are able to communicate, but are unable to communicate between hosts.

What must be changed to enable full inter-VM communications?

20. Anadministrator recently added VLAN 205 CRM in Prism Element. The workloads attached to the associated NICs are unable to establish network connectivity.

Which Layer 2 protocol allows the administrator to troubleshoot this issue from Prism Element?

21. During the Foundation imaging process, nodes are successfully imaged, but the cluster creation fails.

Which log should the consultant review to determine the cause?

22. An administrator is currently using both 10g uplink with LACP and balance-tcp. A single VM should not be allowed to use more than a single 10G uplink, and both uplinks should be utilized.

Which two command should be used to configure the bond? (choose two)

23. While trying to upgrade AOS in a cluster, a consultant receives a warning message that there are two powered-on VMs that need to be powered off for the upgrade to proceed.

What would cause this warning to be issued?

24. An administrator has an existing Nutanix seven-node cluster running at RF2 that must be changed to have the following capabilities:

• RF3 set for the cluster

• Performance tier deduplication

What is the minimum memory needed on the CVMs to allow for these capabilities?

25. An administrator receives a notification that storage in a Nutanix cluster is unavailable. The cluster consists of five nodes and is configured with a Fault-Tolerance level of 1 (FT-1).

Upon investigation, the administrator finds the following:

• All AHV hosts are powered on and the CVMs are running

• Nodes A, B, and C are connected to one top of rack switch

• Nodes D and E are connected to a second top of rack switch
