300-445 Question 108
Select 4You are an enterprise network engineer tasked with identifying intermittent latency issues affecting a critical SaaS application used by your organization. You decide to configure tests using ThousandEyes to diagnose the problem. Which steps would you take to effectively configure these tests and analyze the root cause of the issue?
- A
Set up a Web Layer test targeting the SaaS application's URL to measure HTTP server response times and page load performance.
- B
Configure a Network Layer test with agents placed in key branch offices to trace the path and measure latency to the SaaS application server.
- C
Use ThousandEyes Endpoint Agent to monitor end-user devices and collect DNS resolution data during application usage.
- D
Rely exclusively on Meraki Insights to gather application-level metrics without configuring any tests in ThousandEyes.
- E
Enable alerting for both network and application performance thresholds to proactively detect future issues.
Show answer and explanation
Correct answers: A, B, C, E
Explanation
To diagnose intermittent latency issues affecting a SaaS application, it is crucial to configure both network and application-layer tests using ThousandEyes. A combination of Web Layer, Network Layer, and Endpoint Agent data provides comprehensive insights into potential issues. Alerts further ensure proactive monitoring. While Meraki Insights can complement the analysis, it should not replace the detailed testing capabilities of ThousandEyes.
- A. Correct.
Setting up a Web Layer test in ThousandEyes is essential for monitoring application-level performance metrics, such as HTTP response times and page load performance. This helps isolate issues within the SaaS application itself.
- B. Correct.
Configuring a Network Layer test with agents ensures visibility into the network path to the SaaS server, allowing you to identify any latency or packet loss along the route.
- C. Correct.
Using the Endpoint Agent allows you to monitor user-side performance, including DNS resolution and connectivity, providing critical insights into end-user experiences.
- D. Incorrect.
While Meraki Insights is a useful tool, relying exclusively on it without configuring ThousandEyes tests limits visibility into detailed network and application-layer performance metrics.
- E. Correct.
Enabling alerting for both network and application performance thresholds helps you proactively address potential issues by notifying you in real-time when thresholds are breached.
