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?

  1. change_cvm_vlan 0
    ovs-vsctl set port br0 tag=0
    ovs-vsctl set port br0-up bond_mode=balance-tcp
  2. change_cvm_vlan 10
    ovs-vsctl set port br0 tag=10
    ovs-vsctl set port br0-up bond_mode=balance-tcp
  3. change_cvm_vlan 0
    ovs~vsctl set port br0 tag=0
    ovs~vsctl set port br0-up bond_mode=active-backup
  4. change_cvm_vlan 10
    ovs-vsctl set port br0 tag=10
    ovs-vsctl set port br0-up bond_mode=balance-slb

Answer(s): A



An administrator migrates a VM onto a new Nutanix cluster. After the migration, the administrator observes the following conditions:

· Cluster memory utilization: 64%

· Cluster CPU utilization: 19%

· Clusterstorage utilization: 32%

· Average VM CPU utilization: 25%

· Average VM CPU ready%: 24%

· Average VM memory utilization: 60%

Which two changes should the administrator make to improve VM performance? (Choose two.)

  1. Add more memory to the VMs.
  2. Reduce the number of vCPUs assigned to VMs.
  3. Replace high core count CPUs with high clock rate CPUs. (also can be but is physical invas)
  4. Reduce the number of VMs on the hosts.
