An administrator reviews the error in the exhibit, the examines the state of the cluster, the administrator finds that the AHV host is up and Functional , but the cluster capacity is low.
What will happen to the VMs on the host with this controller VM?
Refer to the exhibit.
An administrator notices a critical alert on the Metro Availability Protection Domain What is causing this alert?
An Administrator has received the following critical alert:
Node 192.168.148.172 is marked to be detached from metadata the administrator has opened a case with Nutanix and the support engineer has requested more information about the error. Which two action should the administrator take in the health check dashboard to collect the requested information? choose two
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.)
An administrator is managing two AHV and vSphere-Based Clusters. The administrator is able to install a Windows Guest OS from an ISO Image to VMWare VMs , but is unable to do the same activity with AHV VMs.
What should the administrator do to successfully perform this action with AHV VMs?
An administrator needs to make sure an RF2 cluster can survive a complete rack failure without negatively effecting workload performance. The current cluster configuration consists of the following:
• 30 nodes: distributed 10 nodes per rack across three 42U rack
• Each nodes is configured with 40TB usable storage all flash (Cluster Total 1.2 PB Usable)
• Current cluster utilization is 900TB storage
Which configuration changes should be made to make sure that the cluster meets the requirements?
An administrator learns that some security settings in a cluster have been changed. The environment is out of compliance with required policies.
Which function should be used to revert any settings that have changed from the defaults and prevent further violations?
An administrator needs to take a single node down for maintenance. Which two steps should the administrator take? (Choose two)
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?
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.)
What is the minimum number of blocks required to utilize block awareness?
A 2
B. 3
C. 4
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?
An administrator needs to expand a cluster based on AHV and running on Nutanix G5 hardware with a new Nutanix G7 system. The cluster is running AOS 5.10 but the operation fails when expanding the cluster. AOS is running on the new system. There are no issues discovering the node.
Why is the operation failing?
An administrator has a 4-node Nutanix cluster running on AHV. The administrator creates
a new storage container and makes that all available to all hosts.
Which storage protocol is used for Virtual Machines to access virtual disks on the storage container?
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?
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 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?
An administrator needs to make sure an RF3 cluster can survive a failure of two complete racks without negatively affecting performance. The current cluster configuration consists of the following:
• 30 All Flash Nodes: distributed 10 nodes per rack across three 42U racks
• Each node is configured with 20TB usable storage all flash (Cluster Total 600TB Usable)
• Current cluster utilization is 500TB storage
• Storage containers have Erasure Coding enabled
Which configuration changes should be made to make sure the cluster meets the requirements?
Refer to the exhibit.
A Nutanix host is connected as shown in the exhibit with br0-up set to active/backup. Physical Switch 1 experiences a power outage causing br0-up to failover to using eth2. The CVM and host become inaccessible. User VMs restart on other hosts in the cluster, which causes a disruption to those VMs.
Which configuration issue likely caused this outage?
An administrator is deploying an application using Nutanix Volumes. After configuring the volume group and connecting the guest's iSCSI initiator to the volume group, they begin performance testing.
The administrator learns that performance on the virtual disk attached to the iSCSI initiator is far less than that of a virtual disk connected directly to the VM.
Which situation is causing this condition?
A New Project is Being rolled out to an AHV Cluster being monitored by prism Central , The Application team indicated that the application managed by the project is very memory intensive . The administrator wants to be notified about any memory constraints should they occur.
How would an administrator most effectively achieve this task?
