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
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.
A customer wants to know the details of network validation testing. Where can the consultant find this information?
A. Handover checklist
B. Test plan
C. Operations Guides
D. As-Built Guide
Explanation: The Test Plan is the most appropriate resource for detailed information on network validation testing. This document typically outlines the specific tests to be conducted to ensure the network meets the required specifications and performance standards necessary for a stable and efficient Nutanix environment. The Test Plan provides a structured approach to validate each network component and interaction, ensuring all aspects are tested and meet design and operational requirements. References: Nutanix Installation and validation procedures as described in Nutanix official documentation and training modules from Nutanix University.
During a six-node cluster deployment, one node fails to image successfully and Foundation is unable to automatically configure the cluster. The consultant decides to manually complete cluster formation with the successful nodes, then expand the cluster with the remaining unconfigured node. Which command should be used to begin the process?
A. cluster status
B. cluster create
C. cluster start
D. cluster expand
Explanation: When deploying a multi-node Nutanix cluster, if one node fails to image and the Nutanix Foundation tool cannot configure the cluster automatically, the consultant can manually create the cluster with the nodes that were successfully imaged. The correct command to initiate this process is cluster create. This command starts the cluster services and allows for further expansion once the cluster is operational, which would include adding the node that initially failed to image.
During Foundation using a customer-provided network switch, a consultant is facing time-out issues. What action should the consultant take to resolve this issue?
A. Check jumbo frames support of the network switch.
B. Ensure the firmware of network switch is updated.
C. Enable queue depth on ports connected to nodes.
D. Disable STP on ports connected to Nutanix nodes.
A customer has requested help deploying a small single-VM instance of Prism Central in their environment that will be used for managing less than 100 guest VMs and registered to a single 5-node cluster. Due to business needs, the customer also plans to consume additional service features within the PC platform.
The consultant discusses with the customer and ultimately decides to deploy a small 3-VM instance to better account for possible resource overhead required once the additional services are enabled on the cluster.
The additional services the consultant must enable to meet the customer’s requests are as follows:
•Nutanix Disaster Recovery
•MS-SQL Server Monitonng
•Flow Microsegmentation
Why won’t the plan to deploy a small PC instance work for this customer?
A. The consultant must specify during the small PC deployment that all 3 PCVMs are configured to have 32GB of memory in order to ensure adequate overhead.
B. The additional services the customer needs cannot be supported on a small sized PC. Consultant must deploy at a minimum a large size PC.
C. Flow Microsegmentation requires an X-Large 5-VM scale-out instance of Prism Central be deployed in order to avoid constraints.
D. MS-SQL Server Monitoring requires additional licensing and a separate appliance to be deployed when using a small sized PC.
Explanation: The plan to deploy a small Prism Central (PC) instance will not work for the customer because the additional services required, especially Flow Microsegmentation and MS-SQL Server Monitoring, demand more substantial resources than a small PC instance can support. The correct approach: B. The additional services the customer needs, including Nutanix Disaster Recovery, MS-SQL Server Monitoring, and Flow Microsegmentation, require a larger resource pool for adequate performance and functionality, making a minimum of a large size PC deployment necessary. Options C and D point to specific requirements but are incorrect in stating the exact size or additional licensing for MS-SQL alone; rather, the overall resource demand across services necessitates a larger PC deployment.References: Nutanix Prism Central Deployment Guide, Nutanix Services Specifications.
