Congestion Management is also Call Admission Control. Without Call Admission Control you have to provide very much bandwidth to be able to guarantee your Quality. I agree on A, B, E.
I agree with Roman.
It is not a question of feelings but passing the exam.
The mentioned Cisco link report:
•Traffic Classification
•Interface Queuing
•Bandwidth Provisioning
I think the correct answer is A,D,E as congestion dosn’t likely happen in a Campus LAN (Swithcing network)
I agree with Saeed.
Call Admission Control implement only in WAN connection.
