An administrator responsible for a VDI environment needs to investigate reports of slow logins. The administrator finds that increasing the number of vCPUs from 2 to 4 will reduce the login times. Production workloads are consuming 75% of the host CPU on the cluster. The administrator increases the vCPU count on all of the VDI VMs. What are two impacts on the cluster? (Choose two.) Increase CPU utilization% Increase CPU ready% Increase memory utilization% Increasing CPU counts will decrease memory utilization. An administrator is using Nutanix Move to migrate a Windows VM from ESXi to AHV. Automated guest preparation is failing with an error: Account has UAC enabled error The administrator is using the local built-in administrator account for the Windows VM Use a Domain Admin account for the Windows VM Reboot the Windows VM and try the migration again Follow manual VM preparation guidelines Place Windows VM in Maintenance Mode. A VM is exhibiting one or more of the following baseline values based on the past 30 days: • CPU usage < 20% • CPU ready time < 5% • Memory usage < 50% (moderately) or < 20% (severely) • Memory swap rate = 0 Kbps Which type of VM is being described? Constrained VM Inactive VM Bully VM Over-Provisioned VM. QUESTION NO: 4 An administrator receives reports that VDI desktop performance in an 8-node Nutanix VDI environment is poor. Opening applications takes between 1 and 2 minutes. When investigating the issue, the following conditions are found: • Cluster memory utilization: 80% • Cluster SSD utilization: 70% • Average VM CPU Wait Time: 11% • CVM CPU utilization: 75% Which action should be taken to improve VDI performance? Increase the amount of SSD storage in the cluster. Add memory to the nodes in the cluster. Add CPU resources to the cluster. Increase the number of vCPU cores allocated to the CVM. 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? Increase the number of cores per vCPU Increase the vCPUs assigned to the VM Span the 2TB disk across four vDisks Add 4GB of memory to the VM. QUESTION NO: 6 A customer recently set up Async Replication between Site A and Site B. The customer wants to conduct a planned failover and clicks Activate on Site B. The customer then runs the following command on Site A: ncli pd deactivate_and__destroy_vms name=<protection_domain_name> What does this do to the customer environment? VMs get deleted from Site B. and the protection domain is now Active. VMs are powered off on Site A and must be manually powered on at Site B. VMs get deleted from Site A and the protection domain is no longer active Customer must then manually power off VMs at Site A and power them on at Site B. 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? Check the Disregard Existing Workloads radio button in the Runway scenario. Check the Disregard Existing Nodes radio button in the Runway scenario. Add up the recovered workloads and manually remove from the Runway configuration. Power down the workloads during a maintenance window and run the Capacity Runway. An administrator is concerned that Prism will be inaccessible if Active Directory is unable to process logins. Which method should the administrator use to access the cluster in the event of this type of outage? Manage the cluster by using the "nutanix" user on the Prism leader CVM Create and use an emergency local account on the cluster Deploy an Active Directory server locally on the cluster Manage the cluster remotely by downloading ncli to a remote workstation. A customer has NearSync configured. When the administrator tries to restore a snapshot from 3 minutes ago, it is not available. The snapshots are happening at 15-minute intervals instead of at the 5-minute configured interval. When the protection domain was initially set up, the snapshots were happening at the expected 5-minute interval. What should the customer do to enable the snapshots to happen at the expected interval? Utilize Metro Availability to meet this requirement Change the protection domain to use Async DR Fix a connectivity issue because the protection domain reverted to Async Configure the protection domain to take snapshots on 15-minute intervals. An administrator inherits a new Nutanix environment and logs in to a CVM to check the network configuration. The configuration is as follows: nutanix@NTNX-16xxxxxxxxx5-A-CVM:xx.xx.xx. 76:~$ manage_ovs show_uplinks Bridge: br0 Bond: br0-up bond_mode: active-backup interfaces: eth3 eth2 lacp: off lacp-fallback: True lacp_speed: slow Bridge: br1 Bond: eth0 bond_mode: active-backup interfaces: eth0 lacp: off lacp-fallback: false lacp_speed: slow Bridge: br2 Bridge: br5 nutanix@NTNX-16XXXXXXXxx5-A-CVM:xx.xx.xx. 76:~$ manage_ovs show_interfaces name mode link speed eth0 1000 True 1000 eth1 1000 True 1000 eth2 10000 True 10000 eth3 10000 True 10000 nutanix@NTNX-16xxxxxxxxx5-A-CVM:xx.xx.xx.76-S Which action should the administrator take to improve network performance? Configure VLAN tagging both on br0 and br1 and their physical interfaces. Add eth0 and eth1 to the br0-up bond Configure balance-sib or balance-tcp mode for br0-up if switch configuration allows Remove one 10 Gbs interface from br0-up to make sure all 10 Gbs can be used. A customer has a primary datacenter with 12 Nutanix blocks distributed across three racks. The customer wants to achieve the most resiliency possible. They also have a datacenter in a branch office that is 400 kilometers away from the primary datacenter. Which two solutions should be used? (Choose two.) Time Stream to a remote site Async DR to a remote site Rack awareness Block awareness. An administrator deploys Exchange on a Nutanix cluster. The administrator creates two containers with RF2 configuration: • One container for Exchange • One container for the other VMs The Exchange VM is experiencing I/O performance issues. Which changes to Storage Optimization should be used on the Exchange container to enhance I/O performance? No data reduction Post process Deduplication only Inline compression and EC-X Inline compression and Deduplication. While creating an image placement policy on the organizations AOS 5.15-based Nutanix cluster, the administrator wants to ensure there are no restrictions on using the selected images on clusters outside of the identified set. What type of Policy Enforcement must the administrator choose? Soft Internal Hard External. An administrator protected a DB VM running on a Nutanix cluster with NearSync Replication, which schedules to repeat every 15 minutes □ to a second site. The daily change rate is low. During nightly backups, the replication window is missed due to write volume. Which two options describe the expected behavior? (Choose two.) NearSync stops working and fails over to the remote site. Protection Domain transitions back to the hourly schedule. The Administrator needs to re-enable it manually. The system continuously tries to get to the NearSync schedule. An administrator is deploying a three-tier application on a Nutanix Enterprise Cloud consisting of web, application, and database VMs. Traffic between the servers must be limited to specific services/ports. There is an application layer firewall VM deployed on one host in the cluster. In which way should the administrator meet this requirement? Create a network for each type of VM, and use policy-based routing to control the traffic flow Configure a security policy and service chain redirecting the server traffic through the firewall Separate the web. application and database VMs on to dedicated VLANs Categorize the VMs in Prism Central and utilize Flow to set a security policy. 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: nutanix@NTNX-16xxxxxxxxx5-A-CVM:xx.xx.xx.76:~$ manage_ovs show_uplinks Bridge: bro Bond: br0-up bond_mode: active-backup interfaces: eth3 eth2 lacp: off lacp-fallback: True lacp_speed: slow Bridge: br1 Bond: eth0 bond_mode: active-backup interfaces: eth0 lacp: off lacp-fallback: True lacp_speed: slow Bridge: br1 Bond: eth0 bond_mode: active-backup interfaces: eth0 lacp: off lacp-fallback: false lacp_speed: slow Bridge: br2 Bridge: br5 nutanix@NTNX-16xxxxxxxxx5-A-CVM:xx.xx.xx.76: $ manage_ovs show_interfaces name mode link speed eth0 1000 True 1000 eth1 1000 True 1000 eth2 10000 True 10000 eth3 10000 True 10000 nutanix@NTNX-16XXXXXXXXX5-A-CVM:xx.xx.xx.76:~$ Which action should be used to troubleshoot without disrupting the VMs running on this node? Check the port on the switch side for any errors Replace the cable from eth2 to the switch Enable balance-s1b on br0-up and monitor if a problem persists Remove eth3 from br0-up and monitor for new alerts. An administrator has an existing cluster and needs to improve performance using AHV Turbo. Which two items are required to achieve even greater performance? (Choose two.) Workloads are multi-threaded. VMs have one vCPU configured. VMs have multi-queue disabled. VMs have more than one vCPU. An administrator is performing a set of routine checks and notes that Prism Central is running with 4 vCPUs and 21 GB RAM. The organizations environment is based on two Nutanix clusters with 170 VMs plus a Legacy vSphere infrastructure. No manual changes have been done on Prism Central VM. Which configuration justifies the current Prism Central configuration? Nutanix Move is running on Prism Central to import VMs from the Legacy Cluster Prism Central was installed for Large Deployment environments. Prism Central is running on the legacy duster and requires more RAM. Nutanix Leap and Nutanix Flow have been enabled on Prism Central. An administrator finds that home shares cannot be configured in a new Files 3.5 deployment. Why is this happening? NFS default access is set to Read Only. Multi-protocol access is not configured. Access Based Enumeration is not enabled. The system is deployed as a single FSVM. A Microsoft SQL 2016 deployment is shown in the exhibit. The administrator receives user reports that database queries take too long to return. Which optimization should be made to this configuration to improve performance? Combine both of the OS and SQL Binaries disks Add a second SCSI controller for the Database TempDB, and Logs disk Separate the Database. TempDB, and Logs onto their own disks Configure the VM to use a PCI disk controller. An administrator of a Nutanix Enterprise Cloud has microsegmentation enabled and a firewall VM installed. The security team notifies the administrator that one of the VMs hosted in the environment has been exhibiting suspect network activity. The administrator wants to isolate the VM from the production network, but must still be able to access it to perform diagnostics. What should the administrator do to meet the requirement? Disable the vNIC on the affected VM Quarantine the VM using the Forensic Method Create a firewall rule that blocks VM traffic but permits diagnostic access Create a security policy with a service chain directing that VMs traffic to the firewall VM. An administrator migrates a VM onto a new Nutanix cluster. After the migration, the administrator observes the following conditions: • Cluster memory utilization: 64% • Cluster CPU utilization: 19% • Cluster storage utilization: 32% • Average VM CPU utilization: 25% • Average VM CPU ready%: 24% • Average VM memory utilization: 60% Which two changes should the administrator make to improve VM performance? (Choose two.) Add more memory to the VMs. Reduce the number of vCPUs assigned to VMs. Replace high core count CPUs with high clock rate CPUs. (also can be but is physical invas) Reduce the number of VMs on the hosts. An administrator is supporting a business critical environment and deploys metro availability to achieve a zero data loss configuration. The two clusters are connected by a 1GbE connection. A new workload is going to be deployed to this cluster. This workload requires a sustained 150MB/S of write throughput and 20MB/s of read throughput. Which change must be made to deploy the workload successfully on this cluster? The bandwidth must be increased to support this workload. The workload must be configured to read at greater than 12.5MB/S. The replication frequency must be less than 60 minutes. Zero data loss nearsync must be used to support this workload. A systems 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.) Perform an Inventory with Life Cycle Management. Determine utilization with Cluster Runway. Enable Deduplication and Erasure Coding. Utilize Optimize Resources for VM efficiency. A guest VM is reported to have poor storage performance. It has an I/O profile of 80% read. 20% write, and the HDDs form more than 50% of the read source. What should an administrator do to resolve this issue? Increase SSD capacity Increase the OPLOG Increase the write cache Use HDDs with higher RPM.
