Select 3Your organization uses ThousandEyes WAN Insights to monitor and optimize application performance across a multi-site WAN setup. The network team has received a notification from WAN Insights indicating suboptimal performance for a critical application between two branch offices. Which of the following actions can be taken based on WAN Insights' recommendations to improve performance?
- A
Adjust routing policies to prioritize traffic for the critical application.
- B
Increase the bandwidth allocation for the WAN link between the two affected branch offices.
- C
Deploy additional ThousandEyes agents at the branch offices for more granular monitoring.
- D
Reroute traffic through an alternative path suggested by WAN Insights.
- E
Upgrade the end-user devices at the branch offices to improve application performance.
Show answer and explanation
Correct answers: A, B, D
Explanation
ThousandEyes WAN Insights provides actionable recommendations to enhance application performance over a WAN. In this scenario, adjusting routing policies, allocating additional bandwidth, or rerouting traffic based on the insights can directly address the suboptimal performance identified. While deploying additional agents or upgrading devices may be beneficial, they do not directly resolve the identified WAN-related performance issue.
- A. Correct.
Adjusting routing policies to prioritize traffic for the critical application is a valid action to ensure that the application receives the necessary resources and reduces latency or congestion.
- B. Correct.
Increasing the bandwidth allocation for the WAN link can improve performance for the critical application by reducing bottlenecks between the two branch offices.
- C. Incorrect.
Deploying additional ThousandEyes agents improves monitoring but does not directly resolve the performance issue. It is a proactive measure rather than a reactive one.
- D. Correct.
Rerouting traffic through an alternative path suggested by WAN Insights can help bypass the problematic path and improve the application's performance.
- E. Incorrect.
Upgrading end-user devices may improve local performance but does not address WAN-related issues, which is the focus of ThousandEyes WAN Insights.
