While troubleshooting the scenario, the Solutions Architect confirms that DynamoDB monitoring metrics are at acceptable levels.<br \/>\nWhich of the following steps would be optimal for debugging these application issues? (Choose two.) <br \/><strong><br \/>A.<\/strong> Parse HTTP logs in Amazon API Gateway for HTTP errors to determine the root cause of the errors. <br \/><strong>B.<\/strong> Parse Amazon CloudWatch Logs to determine processing times for requested images at specified intervals. <br \/><strong>C.<\/strong> Parse VPC Flow Logs to determine if there is packet loss between the Lambda function and S3. <br \/><strong>D.<\/strong> Parse AWS X-Ray traces and analyze HTTP methods to determine the root cause of the HTTP errors. <br \/><strong>E.<\/strong> Parse S3 access logs to determine if objects being accessed are from specific IP addresses to narrow the scope to geographic latency issues.<\/div>\n<p><\/p>\n<style> .hidden-div{ display:none } <\/style>\n<p>\t\t\t\t\t\t\t<button onclick=\"getElementById('hidden-div').style.display = 'block'\"> Show Answer <\/button> <button onclick=\"getElementById('hidden-div').style.display = 'none'\">Hide Answer<\/button><\/p>\n<div class=\"hidden-div\" id=\"hidden-div\"><span style=\"\"><\/p>\n<div class=\"answer\">Correct Answer: <strong>BD<\/strong><\/div>\n<p><strong>Explanation:<\/strong> <\/p>\n<div class=\"explanation\">\nExplanation: Firstly \u201cA 504 Gateway Timeout Error means your web server didn\u2019t receive a timely response from another server upstream when it attempted to load one of your web pages. Put simply, your web servers aren\u2019t communicating with each other fast enough\u201d.
