Question 1

A consultant completes a manual cluster creation of AHV. When the consultant logs into Prism Element, critical error messages appear regarding the hypervisor and NTP.

What component or setting, if misconfigured, would cause these errors?



Answer : B

If the consultant logs into Prism Element and sees critical error messages related to the hypervisor and NTP, this could likely be caused by misconfigured Name Server settings. The Name Server (DNS) is essential for resolving domain names into IP addresses, which are required for NTP operations and overall cluster health checks and communications within the Nutanix environment.

Question 2

A customer has a mail server and needs Nutanix to send email notifications about errors that might occur in Prism. The following information is included under SMTP Server Settings

IP Address of mail server

Port Security Mode

From email address

What should the consultant set up before arriving onsite?



Answer : B

Before arriving onsite, the consultant should set up the SMTP server to allow emails from both the Cluster Virtual IP Address (VIP) and the Controller Virtual Machine (CVM) IP addresses. This setup ensures that Prism can successfully send email notifications through the customer's mail server about any errors or notifications generated by the Nutanix environment, as both the Cluster VIP and CVM IPs are sources from which Prism sends alerts.

Question 3

A consultant is discussing VLAN tagging for a newly deployed Nutanix system. The customer requests that the the vlan dor the CVMs

and AHV hosts be placed in the customer's management VLAN 10. The customer also has VLAN 20 for production VM traffic and

VLAN 30 for backup/replication traffic.

Which VLAN should the consultant recommend for CVM and host traffic?



Answer : A

For a newly deployed Nutanix system where the customer has specified VLAN 10 for management traffic, the consultant should recommend using VLAN 10 for both CVM and AHV host traffic. This VLAN designation ensures that all management, monitoring, and internal cluster communication are on a dedicated network, separate from production VM traffic (VLAN 20) and backup/replication traffic (VLAN 30), thereby enhancing network security and performance.

Question 4

After a consultant runs a bare metal Foundation, the imaging process fails.

In which two locations can the consultant find the logs? (Choose two.)



Answer : C, D

After a failed bare metal Foundation imaging process, the consultant can find relevant logs in two primary locations: on the Foundation VM at '/home/nutanix/foundation/logs' and via the 'View Logs' link available on the Foundation Imaging progress screen. These logs are crucial for diagnosing issues during the imaging process as they provide detailed error messages and operational data. Reference:

Question 5

Which configuration item is a hard requirement to deploy a Nutanix cluster?



Answer : D

The CVM IP address is a hard requirement for deploying a Nutanix cluster. Each CVM must have a unique IP address assigned to it as this IP address is critical for cluster operations, including data replication, management activities, and communication between CVMs and hypervisors. The other options, while important for various functionalities, do not represent a hard requirement for initial deployment. Reference:

Question 6

Which subnet is reserved for CVM internal switch traffic?



Answer : B

The subnet 192.168.254.0/24 is commonly reserved for CVM (Controller Virtual Machine) internal switch traffic within Nutanix environments. This subnet is used internally by the CVMs for management and storage operations that are integral to the Nutanix infrastructure. Using a separate, reserved subnet helps to isolate management traffic from general network traffic, enhancing security and performance. Reference:

Question 7

A customer has an ESXi cluster with two 10GbE NICs on each node and the following requirements.

Solution must follow Nutanix Best Practices

Network configuration should be redundant

A vSphere Distributed Switch will be utilized

Which load balancing configuration should be used?



Answer : A

For a customer using an ESXi cluster with two 10GbE NICs on each node and a vSphere Distributed Switch, the recommended load balancing configuration, following Nutanix Best Practices for redundancy and efficiency, is 'Route based on IP hash.' This setting allows for optimal utilization of network bandwidth and redundancy by distributing the traffic based on the IP address pairings, ensuring a balanced load across the physical NICs.
