Designing Cisco Enterprise Networks (ENSLD) — Question 72

An architect must address sustained congestion on the access and distribution uplinks of a network. QoS has already been implemented and optimized, but it is no longer effective in ensuring optimal network performance. Which two solutions should the architect use to improve network performance. (Choose two.)

Answer options

• A. Configure selective packet discard to drop noncritical network traffic.
• B. Bundle additional uplinks into logical EtherChannels.
• C. Utilize random early detection to manage queues.
• D. Implement higher-speed uplink interfaces.
• E. Reconfigure QoS based on the IntServ model.

Correct answer: B, D

Explanation

The correct answers B and D focus on increasing network capacity and efficiency. Bundling additional uplinks into logical EtherChannels (B) allows for greater throughput, while implementing higher-speed uplink interfaces (D) directly enhances the bandwidth available. Options A, C, and E do not address the fundamental issue of capacity and are less effective in resolving sustained congestion.
