Problem Description:
You are the network administrator for a medium-sized enterprise that relies heavily on its network infrastructure for daily operations. The network consists of multiple Cisco routers and switches interconnected to provide connectivity between various departments and remote offices. Lately, there have been complaints about network performance, including slow data transfer speeds and occasional network downtime. MyECp
Your task is to identify and resolve the network performance issues to ensure optimal network performance. You have access to the Cisco devices' configurations and logs.
Problem Tasks:
Initial Assessment (10 points):
Review the existing network topology and configurations.
Identify any potential bottlenecks or misconfigurations.
Check for any significant errors or warnings in the device logs.
List the key metrics you will use to evaluate network performance.
Performance Analysis (20 points):
Measure the current network performance using the identified metrics.
Identify the areas of the network where performance is suboptimal.
Determine the possible causes of performance issues (e.g., high bandwidth utilization, network congestion, routing problems, etc.).
Provide a brief summary of your findings.
Optimization Plan (15 points):
Develop a comprehensive plan to optimize the network's performance.
Include specific steps to address the identified issues.
Prioritize tasks based on their impact on network performance.
Estimate the time required to implement each optimization.
Implementation (25 points):
Execute the optimization plan, making necessary changes to configurations and network settings.
Document each change and its purpose.
Ensure minimal disruption to ongoing network operations.
Test the network after each optimization step to verify improvements.
Performance Validation (15 points):
Re-measure the network performance using the same metrics as in the initial assessment.
Compare the post-optimization performance with the initial assessment.
Provide evidence of improvements and explain any remaining issues.
Documentation and Recommendations (15 points):
Create a detailed report summarizing the entire optimization process.
Include before-and-after performance metrics.
Provide recommendations for ongoing network monitoring and maintenance to sustain optimal performance.
Note: This problem assumes a basic knowledge of Cisco networking equipment and network troubleshooting. The solution should demonstrate your ability to diagnose and address network performance issues using Cisco technologies.
