300-445 Question 112
Select 3An enterprise network experiences intermittent latency issues affecting critical SaaS applications. The network team uses ThousandEyes and Meraki Insights to identify the root cause. Which actions should the team take to configure the tools and pinpoint the issue effectively?
- A
Set up a ThousandEyes test to monitor end-to-end connectivity between branch offices and the SaaS application.
- B
Configure a Meraki Insights Web App Health test to analyze the performance of the SaaS application's HTTP requests.
- C
Use ThousandEyes to deploy a synthetic transaction test for internal application servers only.
- D
Enable Meraki Insights WAN Health to monitor uplink performance for the affected branch locations.
- E
Configure ThousandEyes to monitor only DNS response times for the SaaS application domain.
Show answer and explanation
Correct answers: A, B, D
Explanation
To diagnose intermittent latency issues affecting SaaS applications, ThousandEyes should be configured for end-to-end connectivity tests to monitor the network path, while Meraki Insights can complement this with Web App Health tests for HTTP performance analysis and WAN Health to check branch uplink performance. These configurations provide a comprehensive view of network and application performance, pinpointing potential issues at different layers.
- A. Correct.
ThousandEyes can monitor end-to-end connectivity, which helps identify latency issues across the network path, including ISPs and SaaS providers.
- B. Correct.
Meraki Insights Web App Health tests analyze HTTP requests and responses, providing detailed insights into SaaS application performance.
- C. Incorrect.
Synthetic transaction tests in ThousandEyes are useful for internal applications but do not apply to external SaaS applications in this scenario.
- D. Correct.
Meraki Insights WAN Health provides metrics like latency, loss, and jitter on WAN links, which are critical for diagnosing branch-level performance issues.
- E. Incorrect.
DNS response time monitoring alone is insufficient to diagnose intermittent latency issues for SaaS applications; broader testing is required.
