55. A Developer wants to use AWS X-Ray to trace a user request end-to-end throughput the software stack. The Developer made the necessary changes in the application tested it, and found that the application is able to send the traces to AWS X-Ray. However, when the application is deployed to an EC2 instance, the traces are not available. Which of the following could create this situation? (Select two.) The traces are reaching X-Ray, but the Developer does not have access to view the records. The X-Ray daemon is not installed on the EC2 instance. The X-Ray endpoint specified in the application configuration is incorrect. The instance role does not have "xray:BatchGetTraces" and "xray:GetTraceGraph" permissions. The instance role does not have "xray:PutTraceSegments" and "xray:PutTelemetryRecords" permissions.
79. A Developer needs to use AWS X-Ray to monitor an application that is deployed on EC2 instances. What steps have to be executed to perform the monitoring? Deploy the X-Ray SDK with the application and use X-Ray annotation. Install the X-Ray daemon and instrument the application code. Install the X-Ray daemon and configure it to forward data to Amazon CloudWatch Events. Deploy the X-Ray SDK with the application and instrument the application code.
138. A Developer wants to enable AWS X-Ray for a secure application that runs in an Amazon ECS environment. What combination of steps will enable X-Ray? (Select THREE.) Create a Docker image that runs the X-Ray daemon. Add instrumentation to the application code for X-Ray. Install the X-Ray daemon on the underlying EC2 instance. Configure and use an IAM EC2 instance role. Register the application with X-Ray. Configure and use an IAM role for tasks.
174. A Developer must analyze performance issues with production-distributed applications written as AWS Lambda functions. These distributed Lambda applications invoke other components that make up the applications. How should the Developer identify and troubleshoot the root cause of the performance issues in production? Add logging statements to the Lambda functions, then use Amazon CloudWatch to view the logs. Use AWS Cloud Trail and then examine the logs Use AWS X-Ray, then examine the segments and errors Run Amazon Inspector agents and then analyze performance.
199. A Development team wants to instrument their code to provide more detailed information to AWS X-Ray than simple outgoing and incoming requests. This will generate large amounts of data, so the Development team wants to implement indexing so they can filter the data. What should the Development team do to achieve this? Add annotations to the segment document and the code Add metadata to the segment document and the code Configure the necessary X-Ray environment variables Install required plugins for the appropriate AWS SDK.
