An administrator receives an alert in Prism indicating that interface eth2, on an AHV host is receiving many CRC errors.
After togging into the problematic host, the following command is run to show the indicated output:
What is causing this issue?
- A . Incorrect link speeds on the switch
- B . The interface is incorrectly configured with Jumbo Frames
- C . A misconfigured bond
- D . A physical layer network problem
B
Explanation: Ref:
rx_crc_errors are caused either by faults in layer 1 (in the past, we have seen failed twinax cables and incorrect types of fibre being used), or issues with jumbo frames on the network. In an environment with 10Gig switches that use cut-through forwarding (Cisco Nexus, Arista, Cisco devices using IOS default to Store and Forward switching), any packets that come into the switch will get forwarded out the destination interface once the switch has read the destination MAC address. If that packet has an MTU over what is configured on the interface, it will cut off the packet at the designated MTU, causing the server to receive a malformed packet, which will throw a CRC error.
If you have a layer 1 issue, you will see rx_crc_errors, not on all but one or two nodes.
Refer to the exhibit.

- B . 15 minutes
- C . 1 hour
- D . 6 hours
B

A customer with a four-node RF2 cluster is adding application VMs to their system. After adding these VMs, the Prism dashboard shows 81% storage utilization.
What is the consequence of running the cluster at 81% storage utilization?
- A . The customer has the ability to add more VMs up to the 100% storage utilization.
- B . There is available capacity in the storage fabric and the cluster is resilient.
- C . Node failure is imminent due to storage utilization.
- D . The cluster is not resilient in the storage fabric
D

An administrator receives an error indicating that the CVMs in the cluster are not syncing to any NTP servers.
An investigation of the issue finds:
• The NTP servers are configured in Prism
• The time on all CVMs is the same
• Both the CVMs and AHV hosts are configured for the UTC time zone.
Which two steps can be taken to troubleshoot this issue? (Choose two.)
- A . Confirm that the NTP servers are reachable from the CVMs.
- B . Restart genesis on all CVMs.
- C . On a CVM. run the command a Hash ntpq -pn.
- D . Restart the chronos service on all CVMs.

A customer needs a DR solution designed around the following requirements:
• There are 8 ms of latency between Sites A and B
• The administrator needs the shortest RPO/RTO possible
• Application consistent snapshots are required
• Use of NutanixVSS
Which Data Protection Method should be used?
- A . Async
- B . Metro Availability
- C . Near Sync
- D . Cloud Connect

After installation, network ports are properly configured with the default active-backup bonding.
One 10GbE port goes to switch 1. Another 10GbE port goes to switch 2. A consultant tests failover by manually pulling one of the cables and notices it is taking too much time to failover, which is causing excessive packet loss.
What should the consultant enable to resolve this issue?
- A . LACP on switch
- B . PAgP
- C . Portfast
- D . Jumbo frames
During a technical call with a customer, it is identified that this installation will be software only on Dell servers. The out-of-band management interfaces will not be given IP addresses until the consultant is onsite.
Which Foundation method should be used for this type of installation?
- A . Bare metal using iDRAC MAC addresses.
- B . Bare metal using LAN MAC addresses.
- C . Bare metal using block serial numbers.
- D . Bare metal using node serial numbers.
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?
- A . Create a network for each type of VM, and use policy-based routing to control the traffic flow
- B . Configure a security policy and service chain redirecting the server traffic through the firewall
- C . Separate the web. application and database VMs on to dedicated VLANs
- D . Categorize the VMs in Prism Central and utilize Flow to set a security policy
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 . The VM’s iSCSI traffic is being routed to the data services IP subnet
- B . The performance test is generating small block random 10.
- C . The duster data services IP address is a bottleneck, shared with other iSCSI traffic
- D . Data Locality ensures that VM attached disks are always faster than iSCSI volumes.
A consultant needs to verify the make and model of the systems that will be imaged with Foundation. The consultant does not have the Bill of Materials (BOM) available to review.
When should the consultant verify the make and model to prepare for the cluster deployment?
- A . During the Foundation Process
- B . While conducting the Tech Review Call
- C . Upon arriving on-site
- D . When reviewing the Statement of Work (SOW)
Refer to the exhibit.
An administrator notices a critical alert on the Metro Availability Protection Domain
What is causing this alert?
- A . Metro Availability Protection domain is active on the remote site.
- B . VMware Site Recovery Manager is handling a failover event
- C . Metro Availability did not fail over and caused an outage.
- D . vSphere moved VMs to the remote container, and the VMs must be moved back.
A

An administrator has a 32-node hybrid cluster with CPU, RAM and storage utilization of 80%. A database VM is configured with VM Flash.
What is causing this IO latency?
- A . Controller VM is experiencing high CPU ready time.
- B . Curator scans causes by ILM constantly moving data.
- C . VM Flash Mode reduces SSD tier capacity for VMs.
- D . Database VM is experiencing high CPU ready time.
A company needs to replicate their VMs to a remote site and must have an RPO of less than 1 hour.
When creating a protection domain, what should an administrator do to meet this requirement?
- A . Enable Async Replication with an RPO of 60 minutes
- B . Enable Near-Sync Replication with an RPO of 15 minutes
- C . Enable Entity Sync on the designated VMs
- D . Enable Availability Zones and send the VM to multiple targets
A
