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.)
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?
An administrator is planning to deploy a Nutanix cluster to support a few high-performance VMs. This deployment will have the following considerations:
* Individual VMs will likely generate network throughputs in the range of 90-100Mbps
* Due to the configuration of the VMs, it is unlikely that a node will host more than one or two of them at a time
* Individual VMs will communicate with only a few (one or two) remote hosts at a time
* Multicast will not be used in the environment
* The hosts are connected via two 1GbE network connections
How should the administrator configure the network bonds to meet this requirement while maintaining the simplest switch configuration?
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?
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 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?
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?
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.)
Refer to the exhibit.
An administrator creates a security policy that isolates their financial application from accessing the Internet When viewing the policy in Prism Central, several connections from the application are outbound to the Internet.
What is causing this issue with the policy?
An administrator is updating disk firmware using LCM and receives the following message:
''there have been 10 or more cluster services restarts within 15 minutes in the Controller VM''
The message appears as each drive is upgraded.
What is the reason this message is being generated?
