A consultant migrated multiple VMs to a new cluster. VMs were previously in VLAN 10.
Why can the VMs no longer communicate on their network?
A. The VNIC type should be set to VMXNET2.
B. The GuestOS firewall is blocking traffic in the new cluster.
C. The VLAN ID is incorrect.
D. Static IP addresses have not been assigned to the new VMs.
Explanation: In scenarios where VMs have been migrated to a new cluster and they were previously on VLAN 10 but can no longer communicate, the most likely cause is that the VLAN ID setting on the virtual network interface cards (VNICs) of the VMs does not match the VLAN configuration of the new network. Ensuring that the VLAN IDs are correctly set to match the network configuration of the new cluster is essential for proper network communication.
Over the period of 2 to 3 weeks, a cluster displays the following:
•Periods where Warning Alerts of memory usage over 75% are asserted
•Periods where Critical Warnings of memory usage over 90% are asserted
•Periods of slow of frozen VDI desktops have caused work stoppage or slowdown
•VDI clones have periodically not powered up when called, causing work stoppage
Which steps should be used to prioritize the administrator’s troubleshooting efforts?
A. •Assess resource health on Hardware page
•Review the Analysis page for memory usage demand
•Determine the VDI workload-to-host affinity across the cluster
B. •Analyze Alert Pages for a root cause of memory problem
•Analyze VM table page to access the VM functionality
•Analyze the VDI Clone properties for possible VDI Workload stress
C. •Check Analysis page for CPU demand
•Verify VDI workload property for memory subscription
•Review the Hardware page to determine if the cluster has sufficient RAM
D. •Review Analysis Page for memory use pattern
•Alert with VDI workload demand
•Analyze current and future workload in the Capacity Runaway tab for sufficient resources
Explanation: For the scenario with memory usage warnings and VDI performance issues, the best approach is to analyze and understand the memory usage patterns and demands on the system. Option D focuses on reviewing the Analysis page to monitor memory use trends and patterns, which is crucial for identifying peak usage times or processes consuming excessive memory. The mention of alerting with VDI workload demand implies the need to monitor and possibly adjust the VDI workload to better fit within available resources. Finally, analyzing current and future workload in the Capacity Runaway tab helps in understanding if the cluster resources are sufficient for the demand, which is critical in planning for capacity management and ensuring that such issues are mitigated moving forward.

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 consultant discovers that while the Foundation VM and the consultant's laptop are able to ping each other nodes are rea discovered while trying to run Foundation on the customer's network. What should the consultant do to resolve the issue?
A. Connect to same switch as the cluster and ping.
B. Install Java on the Foundation VM.
C. Enable IPv6 and multicast on the switch.
D. Enable IPv6 and multicast on the laptop.
Explanation: When Foundation VM and a laptop can ping each other but nodes are not being discovered, it suggests a network protocol issue. The consultant should enable IPv6 and multicast on the switch. Multicast is required for node discovery in many environments, especially when using Nutanix Foundation, as it helps in the detection and communication between nodes and the Foundation VM.
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?
A. CVMs are overwhelmed by disk balancing operations.
B. All VM write operations are going to HDD.
C. All VM read operations are coming from HDD.
D. VMs are unable to perform write operations.
A systems administrator configures a protection domain replication between two Nutanix
clusters. After the first successful replication , the administrator tests DR by clicking
activate on the remote cluster.
While VMs are active on the remote cluster, the protection domain is marked as active on
both clusters.
What steps are required to return both clusters to their original state?
A. 1. On the remote site, deactivate the Protection Domain using ncli
2. On the primary site, select the Protection Domain and dick migrate
B. 1. On the remote site, promote the Protection Domain
2. On the primary site, change the Protection Domain state from Decoupled to Disabled
3 Enable the original primary site as remote site
C. 1. On the prima7 site, suspend replications
2. On the remote site, deactivate the Protection Domain using ncli
3. On the remote site, migrate the protection domain back to the primary site
D. 1 On the remote site, restore the snapshots from the Protection Domain
2. On the remote site, select the Protection Domain and migrate to the primary site
Explanation: To revert both clusters to their original state after testing DR by activating VMs on the remote cluster, the administrator needs to ensure that replications are suspended to prevent any further changes during the process. The steps include suspending the replications on the primary site to prevent any conflicts or data loss (Step 1), deactivating the Protection Domain on the remote site using ncli to stop the DR environment (Step 2), and then migrating the protection domain back to the primary site (Step 3). This sequence ensures that both clusters return to their original states with minimal disruption.
