CCNA: Cisco Certified Network Associate — Question 303

Which two QoS tools provide congestion management? (Choose two.)

Answer options

• A. CBWFQ
• B. FRTS
• C. CAR
• D. PBR
• E. PQ

Correct answer: A, E

Explanation

CBWFQ (Class-Based Weighted Fair Queuing) and PQ (Priority Queuing) are both effective tools for managing congestion in a network. CBWFQ allows for the allocation of bandwidth based on traffic classes, while PQ prioritizes certain types of traffic over others. The other options, FRTS, CAR, and PBR, do not focus specifically on congestion management.
