NCS-Core Practice Test

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?

A. Route based on IP hash

B. Route based on source MAC hash

C. Route based on originating port ID

D. Route based on physical NIC load

A customer needs a DR solution designed around the following requirements:

• There are 8 ms of latency between Sites A and B
• The administrator needs the shortest RPO/RTO possible
• Application consistent snapshots are required
• Use of Nutanix VSS

Which Data Protection Method should be used?

A. Async

B. Metro Availability

C. Near Sync

D. Cloud Connect

A consultant installs a new AHV cluster and moves the cluster into the customer's environment. Alter the move, the consultants notice that traffic is not being balanced across the physical NICs. The ToR switches have been configured with LACP. Within Prism Element, which AHV network option should be set to resolve the issue?

A. Active-Backup

B. Active-Active

C. No Uplink Bond

D. Active-Active with MAC Pinning

A customer is running out of storage in an ESXi cluster. The customer wants to add storage without paying for an additional hypervisor license. Which option should the consultant recommend to meet the requirement?

A. Convert the cluster to AHV to support storage-only node requirements.

B. Select the storage-only checkbox during Foundation and then expand the cluster in Prism.

C. Buy a new node to meet the requirements of the storage-only node specifications.

D. Edit the factory_config.json file to configure the node as storage-only and then expand the cluster in Prism

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
