300-445 Question 248
Select 3An enterprise network is experiencing intermittent latency issues during peak hours, and the IT team has gathered performance data showing high congestion on certain links. To address the issue, the team wants to optimize network capacity planning with minimal disruption to existing services. Which actions should they prioritize?
- A
Implement Quality of Service (QoS) policies to prioritize critical application traffic.
- B
Upgrade the physical links experiencing congestion to higher bandwidth connections.
- C
Redesign the network topology to add additional redundant paths for load balancing.
- D
Migrate all traffic to a single high-performing link to simplify configuration.
- E
Enable compression on existing links to reduce the size of transmitted data.
Show answer and explanation
Correct answers: A, B, C
Explanation
To optimize network capacity planning effectively, the team should combine approaches that address both immediate congestion issues (e.g., QoS policies and link upgrades) and long-term scalability (e.g., topology redesign with redundant paths). Simplistic solutions, like consolidating traffic on a single link, or partial solutions, like compression, do not adequately address the broader challenges of capacity planning in enterprise networks.
- A. Correct.
Implementing QoS policies helps prioritize critical traffic, ensuring important applications maintain performance even during congestion.
- B. Correct.
Upgrading congested links to higher bandwidth connections is a direct way to alleviate network bottlenecks caused by capacity limitations.
- C. Correct.
Redesigning the network topology to include redundant paths provides load balancing and improves overall network resilience against congestion.
- D. Incorrect.
Migrating all traffic to a single link could worsen the congestion issue and does not align with best practices for network optimization.
- E. Incorrect.
While enabling compression can optimize bandwidth for specific use cases, it is not a comprehensive solution for addressing link congestion across the network.
