A consultant deploys a four-node VMware ESXi cluster and vCenter server. An HA/DRS cluster is configured for all four nodes. The customer deploys five new VMs on the cluster. During the knowledge Transfer, a network cable on one node is removed to demonstrate HA and migration of the VMs to another host. In the HA/DRS cluster settings, the VM Restart Priority for all CVMs is set to Disabled. The customer observes warnings that the CVM on the ejected host is no longer powered on. Which ESXi HA/DRS cluster setting is missing?
A. Enable EVC for the cluster.
B. Disable VM Monitoring on all CVMs.
C. Disable Automation Level on all CVMs.
D. Enable Host Monitoring.
Explanation: The issue indicated is that the VMs, specifically the CVMs (Controller VMs), do not restart on the remaining nodes after a network cable is removed, demonstrating a failure of HA (High Availability). The setting that should be verified is "Host Monitoring" within the ESXi HA/DRS settings. This setting enables the host to monitor the state of other hosts in the cluster and take necessary actions like VM restarts on other hosts in the event of failures. If it's disabled, the cluster wouldn't automatically manage the failover of VMs upon host disconnection.
What is the minimum number of nodes required for a Nutanix Cluster to support Replication Factor 3 (RF3) on a storage container?
A. 3
B. 4
C. 5
D. 6
During the knowledge transfer on Prism GUI, a customer asked about AHV best practices for VM High Availability on a five-node cluster and the safest configuration. The consultant informed the customer that best practices dictate that all storage containers are configured with a replication factor of 3.
What will be the behavior if the non-default Guarantee mode is selected on Prism with two AHV host failures?
A. Keeping the default mode will ensure that all VMs can restart in case of two AHV host failures.
B. Keeping the default mode will ensure that all VMs can restart in case of an AHV host failure.
C. Will ensure that all VMs can restart if two AHV nodes remains online.
D. Will ensure that all VMs can restart in case of two simultaneous AHV host failures.
Explanation:
In a five-node cluster with storage containers configured with a replication factor of 3, the behavior of VM High Availability when two AHV host failures occur with the non-default "Guarantee mode" enabled is as follows:
Will ensure that all VMs can restart in case of two simultaneous AHV host failures: This mode prioritizes maintaining VM availability by reserving enough resources to restart VMs even with multiple host failures, as long as at least three hosts (matching the replication factor) remain functional.
A consultant is preparing to foundation over a customer network that has the following criteria:
* VLAN segmented network
* VLAN tags on the nodes must be imaged prior to starting the foundation process.
For each node, the consultant has done the following:
* Connected to the Network Crash Cart of the Node
* Logged in using “root” credentials
What should the consultant do next?
A. 1. CD to /root/nutanix-network-crashcart/
2. Start Network Utility tool by running: ./network_configuration
3. Change Values
B. 1. CD to /home/data/nutanix/nutanix-network-crashcart/
2. Start Network Utility tool by running: ./network_configuration
3. Change Values
C. 1. Log into CVM using nutanix@192.168.5.254
2. CD to /root/Nutanix-network-crashcart/
3. Start Network Utility tool by running: ./network_configuration
4. Change Values
D. 1. Log into CVM using nutanix@192.168.5.254
2. CD to /home/data/nutanix/nutanix-network-crashcart/
3. Start Network Utility tool by running: ./network_configuration
4. Change Values
During Foundation, all nodes are imaged successfully. The cluster creation step fails. The consultant troubleshoots the issue and verifies that all Hosts and CVMs are up and running and responding to network pings. Which method should the consultant select to create the cluster?
A. Log into one of the hosts and run the cluster create command.
B. Image the Bare Metal nodes.
C. Log into one of the CVMs and run the cluster create command.
D. Factory reset the nodes and re-start the Foundation process.
Explanation: After confirming that all nodes (Hosts and CVMs) are operational and network accessible, the next step in troubleshooting a failed cluster creation process is to use one of the CVMs to manually initiate the cluster creation. This is done using the command cluster create from a CVM, which allows you to establish the cluster management and data services provided by Nutanix. This approach is recommended when the Foundation process has successfully imaged the nodes but the automatic cluster creation has failed.
A consultant is showing the Prism Element Web Console to a customer and wants to check that cluster health is OK. During validation, the Health menu raises critical alerts about components using default passwords.
The cluster is based on ESXi as hypervisor, where Prism Central and Nutanix Files are deployed. Passwords have already been changed for a few components, but some of them have been left by default.
How can the consultant check and handle that situation?
A. Activate Cluster lockdown in Prism Element.
B. Check accounts and passwords in Local User Management in the vCenter.
C. Check NCC results and review the associated KB.
D. Deploy and connect the cluster to Prism Security Central.
A consultant is working to setup the network before starting the Foundation process. How should the consultant complete this task?
A. Using the shared IPMI port, ensure that the connected switch can auto-negotiate to 1 Gbps.
B. Disable IPv6 on the network to which the nodes are connected to ensure that IPv6 unicast is blocked.
C. Ensure the IPMI of the nodes are reachable using pre-configured IPMI IPv6 addresses.
D. On Nutanix NX Series, connect the IPMI port and any one of the data ports to the switch.
A consultant creates three storage containers (container-1, container-2, container-3). The customer requires that only container-1, which will be utilized as an NFS datastore, be presented to external hosts. However, users are able to mount all three containers. What is causing this problem?
A. Compression was turned on for all containers.
B. A Container-level whitelist entry was configured.
C. Deduplication was turned on for all containers.
D. A Global whitelist entry was configured.
An administrator is trying to correct high cluster IOPs and Cluster Controller Latency. Networking is the suspected issue. Which networking parameters should be configured in the Nutanix cluster?
A. Bond State and network latency
B. Number of NICs connected and network latency.
C. Number of NICs connected and frame size
D. Number of NICs connected and bond state.
Explanation: When addressing high cluster IOPS and Cluster Controller Latency where networking is suspected to be the issue, it is essential to check the network configuration settings that can directly impact data transfer and latency. The correct answer is to adjust the "Number of NICs connected" and "frame size." Increasing the number of Network Interface Cards (NICs) connected can improve the network throughput and distribute the load more evenly. Adjusting the frame size, particularly setting larger frames (Jumbo Frames), can reduce overhead and improve network efficiency by allowing more data to be transmitted with fewer packets.
Before deploying a new 3-node cluster, a consultant wants to know which VLAN ID to use during Foundation. Where can the consultant find this information?
A. Nutanix Portal
B. As-Built Guide
C. Deployment Questionnaire
D. Test Plan
A Nutanix cluster has 10TB usable storage. The customer wants to create a 100GB datastore for ISO images to eliminate too much storage being consumed by unnecessary images. Which setting should be used to accomplish this goal?
A. From Container Advanced Settings, configure 100GB for advertised capacity.
B. From Container Advanced Settings, enable erasure coding.
C. From Container Advanced Settings, turn on compression and deduplication.
D. From Container Advanced Settings, configure 100GB for reserved capacity.
Explanation: To limit a datastore to a specific capacity within a Nutanix cluster, the best approach is to configure the advertised capacity in the Container Advanced Settings. Setting the advertised capacity to 100GB ensures that this amount of storage is reported to external entities (like hypervisors or operating systems) as the total usable capacity of the datastore, effectively preventing the storage of additional data beyond this limit. This method is preferred over reserving capacity, which guarantees space for specific uses but doesn't limit the total size visible to the system.
A customer wants to ensure that the Data Protection configuration using Protection Domains is fully functional.
The consultant has configured a protection domain for newly-created VMs with static IP addresses on multiple VLANs. The network administrator confirmed that the correct subnets exist at both physical sites.
After performing a failover operation, the virtual machines are turned back on but have no network access.
Which statement describes this issue?
A. Network mappings are not configured for the Remote Site.
B. Nutanix Guest Tools (NGT) are mandatory to use Data Protection.
C. VirtIO drivers need to be reinstalled after a failover.
D. Remote Virtual IP addresses are missing for the Remote Site.
