A consultant has completed a cluster build according to the following requirements:
• Syslog Setup with ERROR level Logging
• Proxy Setup
• SNMP v3 Trap setup
When adding the cluster to an existing Prism Central with a proxy setup, the following error is triggered in the Prism Gateway logs:
Caused by: corn.nutanix.util .base.ValidationException: Prism Central is unreachable What configuration is likely missing?


A. Whitelist of Prism Central OSIP inside of Prism Element and all Prism Element CVMs inside of Prism Central


B. Whitelist of Prism Central VIP inside of Prism Element and Prism Element VIP inside of Prism Central


C. Whitelist of AHV Host IP addresses in Prism Central


D. Whitelist of Prism Central DSIP inside of Prism Element





B.
  Whitelist of Prism Central VIP inside of Prism Element and Prism Element VIP inside of Prism Central

Explanation: The error stating "Prism Central is unreachable" when trying to add a cluster to an existing Prism Central with a proxy setup is likely due to incorrect or missing network routing configurations or firewall rules that do not allow communication between Prism Element and Prism Central. The most likely configuration that is missing and needed to resolve this issue is the whitelist of Prism Central VIP inside of Prism Element and Prism Element VIP inside of Prism Central. Whitelisting these Virtual IP addresses ensures that network traffic between these crucial components of the Nutanix architecture is permitted, thus enabling successful communication and registration of the cluster with Prism Central.

An administrator finds that home shares cannot be configured in a new Files 3.5 deployment. Why is this happening?


A. NFS default access is set to Read Only.


B. Multi-protocol access is not configured.


C. Access Based Enumeration is not enabled.


D. The system is deployed as a single FSVM.





D.
  The system is deployed as a single FSVM.


A consultant is running Foundation discovery with Foundation VM and is unable to dynamically discover the nodes. The consumer needs another method to image the nodes. What information does the consultant need to do bare metal Foundation?


A. Serial # of Block


B. IPMI MAC Address


C. LAN MAC Address


D. Serial # of Node





B.
  IPMI MAC Address

Explanation: When using the Foundation tool for bare metal imaging of Nutanix nodes and dynamic discovery is not possible, the consultant needs the IPMI MAC Address of the nodes. This address is used to identify each node uniquely through its IPMI for remote management purposes, allowing the Foundation VM to interact directly with each node's base management controller (BMC) for the imaging process.

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?


A. SMTP server to allow emails from all IPs in customer network


B. SMTP server to allow emails from Cluster VIP and CVM IP addresses


C. SMTP to allow emails from Cluster VIP


D. SMTP server to allow emails from Host IP addresses





B.
   SMTP server to allow emails from Cluster VIP and CVM IP addresses

An administrator needs to configure snapshots for DR scenarios. The databases get refreshed on Friday nights regularly. The search service application re-indexes the new application on Saturday nights regularly. The remaining front-end and middle tier VMs are static but do get minor version updates weekly.
The administrator needs to have 2 weeks of daily snapshots for all the VMs in an app group and 2 weeks application consist local snapshots only on Fridays, Saturdays and Sundays on the same group of VMs.
Which two options should the administrator use to configure snapshots?


A. Create a schedule in a protection domain for all applicable VMs to snap daily with application consistency enabled with 6 days of retention and with no application consistency and 14 days local retention.


B. Create two consistency groups in a protection domain, one for front-end and middle tier apps with no application consistency, one for database and Search apps with application consistency, and apply the correct schedule to both groups.


C. Create one protection domain for all VMs in an application group with scheduled daily non-application consistent snapshots and another protection domain for all VMs in an application group with scheduled Friday. Saturday, Sunday application consistent snapshots.


D. Create a protection domain for all VMs





C.
  Create one protection domain for all VMs in an application group with scheduled daily non-application consistent snapshots and another protection domain for all VMs in an application group with scheduled Friday. Saturday, Sunday application consistent snapshots.

After finishing foundation on an AHV cluster, a consultant is preparing to plug into the customer network given the following set of requirements:

* All network traffic on trunks is tagged
* Customer is using LACP
* A native VLAN is not in use

Which set of commands should the consultant use to ensure cluster connectivity on customer equipment?


A. change_cvm_vlan 0 ovs-vsctl set port br0 tag=0 ovs-vsctl set port br0-up bond_mode=balance-tcp


B. change_cvm_vlan 10 ovs-vsctl set port br0 tag=10 ovs-vsctl set port br0-up bond_mode=balance-tcp


C. change_cvm_vlan 0 ovs~vsctl set port br0 tag=0 ovs~vsctl set port br0-up bond_mode=active-backup


D. change_cvm_vlan 10 ovs-vsctl set port br0 tag=10 ovs-vsctl set port br0-up bond_mode=balance-slb





B.
  change_cvm_vlan 10 ovs-vsctl set port br0 tag=10 ovs-vsctl set port br0-up bond_mode=balance-tcp

Explanation: Considering the network configuration requirements—where all trunk traffic is tagged and a native VLAN is not used—the consultant must set up the CVM and bridge to operate with a specific VLAN tag. The command change_cvm_vlan 10 configures the Controller VM (CVM) to communicate over VLAN 10. The command ovs-vsctl set port br0 tag=10 applies VLAN 10 tagging to the bridge interface br0, ensuring all traffic through it is appropriately tagged. The command ovs-vsctl set port br0-up bond_mode=balance-tcp sets the bonding mode to balance-tcp, which is suitable for environments using LACP to optimize traffic distribution and redundancy across multiple physical links.References: Nutanix Community Documentation, Nutanix University Networking Best Practices.
