Company ABC has intermittent problems registering remote-site IP phones over the WAN with Cisco Unified CallManager at headquartes. The Company hires a network consultant to help implement QoS in its network. Which technique should the consultant use to identify traffic and applications that traverse the network?
A. NBAR
B. RSVP
C. Policing
D. Priority queuing
I think A answer is corect becauce RSVP is Resource Reservation Protocol and he is responsibility for reservation bandwidth
It’s NBAR since the question is for “identify traffic and applications”, and RSVP should be the right solution for the problem described above but not correct answer.
