• A. Analytics Database
• B. OpenStack
• C. Virtual Network Function Manager (VNFM)
• D. Contrail Command

You have deployed a load-balancing service for a customer in your Contrail cloud networking environment for their data cache system. Due to the network capacity requirements, the caching servers must be migrated to a different rack of equipment within the data center.
Which two statements are true in this scenario? (Choose two.)

• A. The load-balancing service must be decommissioned and re-provisioned once the caching servers are moved.
• B. The load-balancing service can be migrated to the vRouters where the caching servers are located.
• C. A new load-balancing service will be provisioned by the orchestrator prior to moving the caching servers.
• D. The orchestration platform can remap the traffic through the existing load-balancing service once the caching servers are moved.

You are required to implement a Contrail service that will automatically increase network resources for that service when under high traffic loads, and reduce network resources for that service under low traffic loads.
Which configuration steps will accomplish this task?

• A. Configure Ceilometer to monitor the CPU threshold of services VMs, and configure a Ceilometer auto-scaling policy to adjust the VM resources allocated to the service.
• B. Configure Heat to monitor the CPU threshold of services VMs, and configure a Heat auto-scaling policy to adjust the VM resources allocated to the service.
• C. Configure Ceilometer to monitor the CPU threshold of services VMs, and configure a Heat auto-scaling policy to adjust VM resources based on the alarms generated by Ceilometer
• D. Configure Heat to monitor the CPU threshold of services VMs, and configure a Ceilometer auto-scaling policy to adjust the VM resources based on alarms generated by Heat.

Which command displays routes in vRouter VRF?

• A. route print
• B. show route table vrf-name
• C. rt
• D. show route
