300-445 Question 109
Select 3Your organization has been experiencing intermittent connectivity issues between a branch office and a critical SaaS application hosted in the cloud. You are tasked with configuring tests using ThousandEyes to pinpoint the root cause of the issue. Which of the following steps should you take to configure an effective test and analyze the issue?
- A
Set up a Network Layer test from the affected branch office to the SaaS application endpoint.
- B
Configure a Web Layer test to monitor the HTTP performance of the SaaS application.
- C
Enable BGP route monitoring to identify potential routing issues between the branch office and the cloud provider.
- D
Use Meraki Insights to configure a WAN Health test for the branch office.
- E
Set up an Alert Rule in ThousandEyes to notify you of network latency over a predefined threshold.
Show answer and explanation
Correct answers: A, B, C
Explanation
To effectively diagnose intermittent connectivity issues between a branch office and a SaaS application using ThousandEyes, it is essential to configure tests targeting both the network and application layers. A Network Layer test helps identify connectivity and routing issues, while a Web Layer test evaluates application performance. Additionally, enabling BGP route monitoring can reveal routing problems along the path. These steps together provide comprehensive coverage of potential root causes. Meraki Insights and alert rules, while useful in other scenarios, are not directly relevant to this configuration process.
- A. Correct.
Correct: A Network Layer test in ThousandEyes helps monitor connectivity, packet loss, and latency between the branch office and the SaaS application endpoint, which can identify network-related issues.
- B. Correct.
Correct: Web Layer tests in ThousandEyes can assess the SaaS application's HTTP performance, which might reveal application-layer issues such as slow response times or timeouts.
- C. Correct.
Correct: Enabling BGP route monitoring in ThousandEyes can help uncover routing anomalies, such as route flapping or misconfigurations, which may affect the connectivity.
- D. Incorrect.
Incorrect: While Meraki Insights is a valuable tool, it is not part of the ThousandEyes platform and is used for other purposes, such as monitoring WAN performance for Meraki networks. It does not contribute directly to the configuration of tests in ThousandEyes.
- E. Incorrect.
Incorrect: Although setting up an Alert Rule in ThousandEyes is useful for proactive monitoring, it is not a step directly involved in configuring or identifying the root cause of connectivity issues.
