How can an engineer determine location-based CAC bandwidth requirements for Cisco Unified communication Manager?

Question

Options

• AExecute the Resource Reservation protocol to return location-based requirements.
• BCalculate the number of calls against the license for Cisco Unified Border Element to determine
• CSet the requirements in the service parameters.
• DAdd the requirements for each audio and video codec and how many calls must be supported.

• A
  8% (4)
• B
  2% (1)
• C
  4% (2)
• D
  87% (46)

Explanation

Location-based Call Admission Control (CAC) in Cisco Unified Communications Manager (CUCM) restricts bandwidth usage between sites to prevent oversubscription of WAN links. To configure locations correctly, an engineer must manually calculate the total bandwidth needed by summing the per-call bandwidth for each codec type multiplied by the maximum number of simultaneous calls. For example, G.711 requires ~80 kbps per call (including IP/UDP/RTP overhead) and G.729 requires ~24 kbps per call. Video codecs have their own bandwidth requirements. RSVP (Resource Reservation Protocol) can assist with per-call signaling but does not auto-configure location bandwidth limits. Licensing and service parameters are unrelated to bandwidth calculation.
