Designing for Cisco Internetwork Solutions (DESGN, legacy) — Question 45
A campus network needs end-to-end QoS tools to manage traffic and ensure voice quality. Which three types of QoS tools are needed? (Choose three.)
Answer options
- A. interface queuing and scheduling
- B. congestion management
- C. compression and fragmentation
- D. bandwidth provisioning
- E. traffic classification
- F. buffer management
Correct answer: A, D, E
Explanation
The correct answers, A, D, and E, are critical for ensuring Quality of Service in a campus network. Interface queuing and scheduling help prioritize traffic, bandwidth provisioning ensures sufficient resources for voice, and traffic classification identifies and manages different types of traffic. Options B, C, and F, while related to network management, do not directly address the end-to-end QoS needs for voice quality.
