質問 6

Which of the following statements regarding Service Chain of the Agile Controller are true? (Multiple Choice)

A. A service device processes the service flows directed to it by an orchestration device. Generally, firewall, antivirus, and online behavior management devices can function as service devices.

B. An orchestration device, usually a switch, directs service flows to a service device.

C. The Service Chain component uses a user control list (UCL) to implement access control by user level. The ACL rules are defined based on the source security group, destination security group, and port number.

質問 7

On a carrier's MPLS VPN network, PE1 and PE2 transmit data packets between VPNs. After PE1 receives VPN route 172.16.1.0/24 from a client, it converts the route into a VPNv4 route and distributes label 1027 to the packet. After the packet arrives at PE2, PE2 distributes label 1025 to the packet.
When a client on PE2 accesses this route, what are the outer and inner labels in the packet transmitted over the carrier network?

A. Outer label: 1025; inner label: 1027

B. Outer label: 1027; inner label: 1025

C. Outer label: 1025; inner label: 1025

D. Outer label: 1027; inner label: 1027

正解: A

質問 8

What are the advantages of NFV? (Multiple Choice)

A. Uses the unified software versions for devices and uniformly manage access tenants.

B. Shorten the network service innovation period.

C. Provide services for different applications and tenants through the single platform.

D. Reduce device and energy cost.

正解: B,C,D

質問 9

MPLS supports multi-layer labels and connection-oriented on the forwarding plane, therefore it is widely used.
