300-445 Question 107
Select 3You are tasked with monitoring the performance of a web application hosted in a public cloud environment to ensure optimal end-user experience. You decide to configure tests using ThousandEyes and Meraki Insights. Which of the following configurations will help you achieve this objective effectively?
- A
Set up synthetic transaction monitoring in ThousandEyes to simulate user interactions with the web application.
- B
Use Meraki Insights to analyze WAN latency, jitter, and packet loss for traffic destined to the cloud-hosted application.
- C
Configure ThousandEyes to monitor BGP route changes for the public cloud provider hosting the application.
- D
Leverage Meraki Insights' Wi-Fi health metrics to isolate issues in the internal network affecting application access.
- E
Enable real-time DNS resolution monitoring using ThousandEyes for the application's public domain.
Show answer and explanation
Correct answers: A, B, E
Explanation
To effectively monitor the performance of a cloud-hosted web application, you need to simulate user interactions using ThousandEyes, analyze network performance with Meraki Insights, and ensure DNS resolution is functioning correctly. These configurations collectively address application performance from both the network and application layers, ensuring a comprehensive monitoring approach.
- A. Correct.
Correct: Synthetic transaction monitoring in ThousandEyes can simulate user interactions to provide insights into application performance and identify issues such as slow response times.
- B. Correct.
Correct: Meraki Insights is useful for analyzing network performance (e.g., latency, jitter, packet loss), which can directly impact the end-user experience for cloud-hosted applications.
- C. Incorrect.
Incorrect: While BGP route monitoring in ThousandEyes is useful for tracking global routing changes, it is not directly relevant to the end-user performance of the web application in this scenario.
- D. Incorrect.
Incorrect: Wi-Fi health metrics in Meraki Insights are focused on diagnosing internal wireless network issues, which may not be directly related to the cloud-hosted application's performance if the issue lies outside the internal network.
- E. Correct.
Correct: DNS resolution monitoring in ThousandEyes helps ensure that the application's domain is resolving correctly, which is critical for end-user access and performance.
