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.
A consultant successfully installs the Foundation VM on a laptop and needs to ensure the VM can communicate externally. Which two configuration changes should the consultant make next? (Choose two.)
A. Ensure the vNIC is set to bridged adapter.
B. Configure the static IP address through the desktop virtualization software.
C. Open terminal and configure via ifconfig command.
D. Run the set_foundation_ip_address application on the VM desktop.
Explanation: To ensure that the Foundation VM can communicate externally, the virtual network interface card (vNIC) should be set to a bridged adapter. This setting allows the VM to appear as a unique entity on the network, receiving its own IP address accessible from outside the host machine. Additionally, running the 'set_foundation_ip_address' application on the VM desktop enables the consultant to configure a specific, reachable IP address for the Foundation VM, ensuring it can communicate effectively with external network resources and devices.
A systems administrator needs to add more VMs to their Nutanix cluster. Which two actions should the administrator perform to determine if the current cluster can accommodate the new VMs? (Choose two.)
A. Perform an Inventory with Life Cycle Management.
B. Determine utilization with Cluster Runway.
C. Enable Deduplication and Erasure Coding.
D. Utilize Optimize Resources for VM efficiency.
An administrator configure Active Directory (AD) authentication for their Nutanix environment. When login in using an AD user account, the login process takes more than one minute to complete. No delay occurs when logging a local account.
What should the administrator confirm to resolve this issue?
A. The user search base for the group is configured correctly
B. The domain controller being used is configured as a global catalog server.
C. Active directory lookups are configured to use Non-Recursive mode.
D. The service Account Username is correct for the domain.
Explanation:
In a Nutanix environment, if the login process using an Active Directory (AD) user account takes more than a minute to complete, it could be due to the configuration of the AD lookups.
Active Directory lookups can be configured to use either Recursive or Non-Recursive mode. In Recursive mode, the system will look up each group that a user is a member of, then each group that those groups are members of, and so on. This can lead to a large number of lookups and potentially slow down the login process1.
On the other hand, in Non-Recursive mode, the system only looks up the direct groups that a user is a member of. This can significantly reduce the number of lookups and speed up the login process1.
Therefore, the administrator should confirm that Active Directory lookups are configured to use Non-Recursive mode to resolve this issue.
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?
A. Cluster Lockdown with strong password enforcement
B. Advanced Intrusion Detection Environment (AIDE)
C. Security Configuration Management Automation (SCMA)
D. Defense Information Systems Agency STIG enforcement
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?
A. AOS version running on G7 is older than the version on the cluster.
B. Foundation software has not been updated on the cluster.
C. G7 hardware cannot be added to a G5 cluster.
D. EVC needs to be configured before cluster expansion
A consultant is conducting a vSphere cluster deployment. As a part of operational tests, a vMotion operation is performed on a test VM, but fails with following error message:
The VMotion failed because the ESX hosts were not able to connect over the VMotion network. Please check your VMotion network settings and physical network configuration.
VMotion [184329483:1276605211167987] failed to create connection with remote host <10.10.16.14>: The ESX hosts failed to connect over the VMotion network Migration [184329483:1276605211167987] failed to connect to remote host <10.10.16.14>: Timeout
What issue could prevent the vMotion operation from completing successfully?
A. The vmknic is configured with a conflicting IP address.
B. NIOC is enabled and vMotion traffic is configured with Share value SO.
C. Foundation service prevents connectivity between the source and the destination TCP port 8000.
D. The vSS is configured with Route based on originating virtual port.
Explanation: The failure of the vMotion operation indicated by the error message could most plausibly be caused by: A. The vmknic (VMkernel network interface card) configured with a conflicting IP address. This conflict can prevent the ESXi hosts from establishing a connection over the VMotion network, as each host must have a unique IP address on the VMotion network to facilitate proper migration communications. Option B, involving NIOC settings, and option D, involving vSS configuration, could influence performance but are less likely to cause a complete failure to connect. Option C, related to the Foundation service, is not relevant to vMotion networking issues directly. References: VMware vSphere Networking Documentation, Nutanix Integration with VMware Environments.
