Which two properties of User CDRs that are part of CDR-based reports for planning and reviewing telepresence network usage are valid? (Choose two )

Question

Options

• AUser CDRs are generated only on the Cisco VCS that the endpoint making the outbound call is
• BUser CDRs are generated only for incoming calls
• CCisco TMS retains zero duration calls when resolving feedback from the Cisco VCS.
• DUser CDRs in Cisco TMS should be considered best effort.
• ECisco VCSs under heavy load can fail to send feedback events to cisco TMS, but they retry five

• A
  8% (2)
• C
  88% (23)
• D
  4% (1)

Explanation

Answer C is correct: Cisco TMS retains zero-duration calls when resolving feedback from Cisco VCS - this is by design to ensure completeness of records even when calls connect but immediately disconnect. Answer E is correct: Cisco VCS systems under heavy load can fail to send feedback events to TMS, but they attempt to retry (five times) before giving up, making CDR data best-effort under stress conditions. Answer A is incorrect because CDRs can be generated on both sides of a call. Answer B is incorrect because CDRs cover both inbound and outbound. Answer D is partially true in spirit but E more precisely captures the retry behavior, making D a distractor.
