CHAPTER 10 (Optimizing & Testing Your Network Design)

In the context of network management, which combination of mechanisms provides effective control over congestion, ensuring fair bandwidth allocation and minimizing packet loss?

• Random Early Detection (RED) for adaptive dropping, Traffic Shaping for rate control, and Committed Access Rate (CAR) for policing

• Random Early Detection (RED) for priority queuing, Traffic Shaping for burst control, and Committed Access Rate (CAR) for shaping

• Random Early Detection (RED) for probabilistic queuing, Traffic Shaping for adaptive rate control, and Committed Access Rate (CAR) for prioritization

• Random Early Detection (RED) for dynamic marking, Traffic Shaping for latency control, and Committed Access Rate (CAR) for fairness

What the purpose of optimization network?

• To minimize the cost of network infrastructure

• To maximize computational speed

• Meet key business and technical goals

• To enhance cybersecurity measures

Which technology among the following is specifically designed to provide bandwidth reservation and ensure predictable performance for applications in a network environment?

• IETF controlled load service

• IETF guaranteed service

• IP precedence

• IP differentiated services

Which Cisco queuing technique provides preferential treatment to a designated queue, typically recommended for real-time voice traffic, while also allowing the classification of various traffic types based on protocols, access control lists, and interfaces?

• Weighted Fair Queuing (WFQ)

• Custom Queuing

• Low Latency Queuing (LLQ)

• First In, First Out (FIFO) Queuing
