QuestionQ12

Services Architecture

On a Nokia 7750 SR, the OAM command svc-ping supports the local-sdp and remote-sdp options. Which statement below is TRUE?

  • A 'local-sdp' and 'remote-sdp' indicate that all services using these SDPs are pinged.
  • B 'local-sdp' and 'remote-sdp' indicate that pings are initiated from both local and remote routers.
  • C Both 'local-sdp' and 'remote-sdp' take parameters to specify which SDPs are used for the test.
  • D 'local-sdp' indicates that the ping is sent in-band, and 'remote-sdp' indicates the return ping is in-band.
Explanation

local-sdp causes the svc-ping request to use the service tunnel’s encapsulation and service labeling (in-band), and remote-sdp causes the far-end response to use the same service encapsulation and labeling (in-band).
