300-445 Question 110
Select 2An organization uses both ThousandEyes and Meraki Insights for enterprise network assurance. The IT team is experiencing intermittent latency issues in a branch office and wants to configure tests to identify whether the problem lies with the WAN link, internal network, or an external SaaS application. Which of the following tests should they configure to effectively isolate the issue?
- A
Configure a ThousandEyes Network Layer test to measure packet loss and latency across the WAN link.
- B
Use Meraki Insights to perform Application Health monitoring for the targeted SaaS application.
- C
Set up a ThousandEyes HTTP Server test to evaluate the performance of internal web servers.
- D
Enable Meraki Client Insights to monitor device-level performance within the branch office.
- E
Configure a ThousandEyes DNS Server test to identify potential DNS resolution delays.
Show answer and explanation
Correct answers: A, B
Explanation
To effectively isolate the cause of intermittent latency issues, the IT team should focus on tools and tests that target the WAN link and SaaS application performance. ThousandEyes Network Layer tests provide insights into WAN link performance metrics, while Meraki Insights' Application Health monitoring focuses on external SaaS application performance. The other options are not relevant to diagnosing the described latency issue.
- A. Correct.
This is correct because a ThousandEyes Network Layer test is designed to assess WAN link performance by measuring metrics like latency, packet loss, and jitter. This would help isolate WAN-related issues.
- B. Correct.
This is correct because Meraki Insights' Application Health monitoring is specifically designed to evaluate the performance of SaaS applications, identifying potential bottlenecks in application delivery.
- C. Incorrect.
This is incorrect because a ThousandEyes HTTP Server test is targeted at assessing web server performance, which is not directly relevant to diagnosing WAN or SaaS application issues in this case.
- D. Incorrect.
This is incorrect because Meraki Client Insights focuses on device-level performance metrics, which would not help identify issues with the WAN link or SaaS application performance.
- E. Incorrect.
This is incorrect because a ThousandEyes DNS Server test is used for detecting DNS resolution delays, which is unrelated to the latency issues described in the scenario.
