Exam AWS Certified Solutions Architect - Professional topic 1 question 401 discussion

B and D are correct. Firstly “A 504 Gateway Timeout Error means your web server didn't receive a timely response from another server upstream when it attempted to load one of your web pages. Put simply, your web servers aren't communicating with each other fast enough”. This specific issue is addressed in the AWS article “Tracing, Logging and Monitoring an API Gateway API”. https://docs.amazonaws.cn/en_us/apigateway/latest/developerguide/monitoring_overview.html The article specifically discusses using AWS X-Ray, AWS CloudTrail and AWS CloudWatch as the tools to utilized for debugging in this scenario. The two options that encompass using AWS CloudWatch and AWS X-Ray are B and D respectively. AWS CloudTrail is not mentioned in any of the answers.

The correct answers are BD. https://docs.aws.amazon.com/en_pv/apigateway/latest/developerguide/monitoring_overview.html

The optimal steps for debugging the application issues are as follows: B. Parse Amazon CloudWatch Logs to determine processing times for requested images at specified intervals. By analyzing the CloudWatch Logs, you can identify the processing times for requested images. This will help in identifying any performance bottlenecks or delays in processing the dynamic images. D. Parse AWS X-Ray traces and analyze HTTP methods to determine the root cause of the HTTP errors. By using AWS X-Ray, you can trace and analyze the execution of your application components. Analyzing the X-Ray traces will provide insights into the execution flow and help identify any issues with the HTTP methods that could be causing the 504 Gateway Timeout errors.

OPTION A & D OUTPUT from Chat GBT Both options of parsing the HTTP logs in Amazon API Gateway and parsing Amazon CloudWatch Logs are valuable for debugging the issues in the serverless application. Parsing the HTTP logs in Amazon API Gateway is useful for identifying and resolving the 504 Gateway Timeout error, as it provides information about the specific requests that are timing out and any related error messages. Parsing Amazon CloudWatch Logs is useful for identifying performance bottlenecks and resolving slowdowns in the application components, as it provides information about the processing times for the images and can help identify any potential issues with processing speed. It may be best to implement both options to gain a comprehensive understanding of the issues and effectively resolve them.

b and d look right

B,D is right

Answer is B＆D

It's B D

The correct answer is BD

I'll go with B,D

https://aws.amazon.com/premiumsupport/knowledge-center/api-gateway-504-errors/

Ans B,D for me

D for sure. X-Ray is basic for performance monitoring. Between A and B, 504 is the gateway timeout returned by the API gateway. But B talks about processing time in other components which most likely is what caused the time out. So I vote for B. B& D B & D

Answer is BD E is irrelevant

B & D is the correct answer.

I will go B&D

Correct answer is BD
