• Question 123:

  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.

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: 1027; inner label: 1025
  B. Outer label: 1025; inner label: 1025
  C. Outer label: 1027; inner label: 1027
  D. Outer label: 1025; inner label: 1027
  D. Outer label: 1025; inner label: 1027

• Question 124:

  What are the mainly methods of data collection? (Multiple Choice)

  B. Collection through port mirroring
  C. Centralized collection by NMS
  D. Automatic collection
  A. Collection by physical optical splitter
  B. Collection through port mirroring
  C. Centralized collection by NMS
