Question 1

An organizations Nutanix Cluster is based on VMware vSphere. The cluster is configured to download software updates automatically. The administration needs to verify and eventually upgrade VMware hypervisor via Prism Ul. After logging in to Prism, the administrator receives the message shown: No available versions for upgrade. What is causing the current state?

Accepted Answer

The answer of An organizations Nutanix Cluster is based on...

Question 2

A new Nutanix cluster is ready for production on a remote site with no IT staff. Changes to the infrastructure will cost money and probably cause a cluster stop. The administrator needs to perform a health check on the environment that should include: Network connectivity checks Network performance status Storage performance status Which tool should be used to perform this test?

Accepted Answer

NCC (Nutanix Cluster Check) is a tool specifically designed to perform health checks on Nutanix clusters, including network connectivity, network performance, and storage performance status.

Question 3

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?

Accepted Answer

Question 5

A three-node cluster has a Nutanix Files instance with three FSVMs. What happens after a node failure?

Accepted Answer

The affected FSVM will be restarted on another node to maintain the availability and functionality of the Nutanix Files instance.

Question 6

An administrator is deploying an application that requires maximum I/O throughput for scratch data. The administrator is concerned that the throughput requirement is greater than what can be provided by a single cluster node. What should the administrator do to meet this requirement?

Accepted Answer

Creating a volume group with several virtual disks and attaching it to the VM can distribute the I/O load across multiple disks, increasing the overall throughput and meeting the application's requirements.

Question 7

An administrator inherits a new Nutanix environment and logs in to a CVM to check the network configuration. The configuration is as follows:  Which action should the administrator take to improve network performance?

Accepted Answer

The answer of Refer to the exhibits. An administrator has...

Question 9

Microsegmentation was recently enabled in a Nutanix environment. The administrator wants to leverage Prism Central to create a policy that will block all traffic, regardless of direction, between two groups of Vms identified by their category. Which policy should be used to meet this requirement?

Accepted Answer

An Isolation Environment Policy is used to block all traffic between groups of VMs, making it suitable for the requirement to block all traffic between two groups of VMs identified by their category.

Question 10

A Nutanix cluster is deployed with the following configuration: Three four-node blocks (A, B, and C) All Flash Redundancy Factor 2 What is the effect of simultaneous disk failures on two nodes located in block A?

Accepted Answer

Dual Disks Failures: With Replication Factor = 2, we have two copies of each data block. Also, with a 4TB Disk which is only 1TB utilized, we will have 1TB worth of blocks/data across the cluster (shorter rebuild times as we factor in the capacity utilized) - plus with AOS proactive disk alerting, so, unless two disks are pulled at the same time, this can be a very rare occurrence of two drives failing at the same time.

Question 11

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?

Accepted Answer

rx_crc_errors are caused either by faults is 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 10 Gig 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.

Question 12

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?

Accepted Answer

The answer of An administrator is performing a set of...

Question 13

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?

Accepted Answer

Soft policy enforcement allows flexibility and does not impose strict restrictions, enabling the use of images on clusters outside of the identified set.

Question 14

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.)

Accepted Answer

Confirm that the NTP servers are reachable from the CVMs.Run the command hash ntpq -pn on a CVM to check the NTP server status.

Question 15

Refer to the exhibit.  An administrator configures Active Directory authentication as shown in the exhibit. Upon finishing setup, users are not able to log in. What configuration change should be made to fix this issue?

Accepted Answer

The answer of Refer to the exhibit.  An administrator...

Question 16

An administrator is migrating 5MB shares from a third-party platform to Nutanix Files with the following characteristics: Shares contain user profile directories DFS-N will be used How should the administrator create target shares for this migration?

Accepted Answer

Distributed shares with multiple top-level directories are suitable for handling user profile directories and can efficiently distribute the data, especially when using DFS-N for namespace management.

Question 17

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.)

Accepted Answer

The answer of An administrator protected a DB VM running...

Question 18

A customer wants to run SAP HANA on a Nutanix cluster with the following characteristics: AHV nodes SAP HANA version 2 Production database files Which configuration should be recommended to the customer?

Accepted Answer

Do not configure storage-saving functionalities such as compression, deduplication, or erasure coding (EC-X) on a storage container that holds production database files. Because of the way the SAP HANA Persistence Engine stores data, these features deliver no benefits. Nutanix SAP Engineering has tested compression with SAP HANA workloads; the tests indicate no noticeable performance impact but also show no reduction in the space the SAP HANA workload consumes.

Question 19

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.)

Accepted Answer

The signed, intermediate and root certificates are chained and the imported files for the custom certificate must be PEM encoded.

Question 20

An administrator needs to migrate workloads from a Nutanix cluster running VMware ESXi to Nutanix AHV. The migration process needs to be completed in multiple VM groups and support roll back in case any problems are found during user acceptance testing. Which action should the administrator perform?

Accepted Answer

Nutanix one-click cluster conversion from ESXi to AHV is the recommended method for migrating workloads from a Nutanix cluster running VMware ESXi to Nutanix AHV. This method supports roll back in case any problems are found during user acceptance testing.
