Refer to the exhibit.
You have a Contrail providing cloud services to Customer A. Customer A wants to add a packet capture service to their network to analyze traffic flowing to and from the Internet.
Referring to the exhibit, which statement is true?
A. The packet sniffing service must be performed on the edge routers facing the Internet.
B. The packet sniffing service must be enabled on the vRouter directly attached to the customer’s VM.
C. The packet sniffing service can be implemented on any physical host in the cloud environment.
D. The packet sniffing service can be implemented on any switch within the underlay fabric.
Answer: B
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 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.
B . 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.
C . 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.
D . 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
Answer: D
