Question 102

A developer has written a distributed application that uses micro services. The microservices are running on Amazon EC2 instances. Because of message volume, the developer is unable to match log output from each microservice to a specific transaction. The developer needs to analyze the message flow to debug the application.

Which combination of steps should the developer take to meet this requirement? (Select TWO.)

Options:

Download the AWS X-Ray daemon. Install the daemon on an EC2 instance. Ensure that the EC2 instance allows UDP traffic on port 2000.

Configure an interface VPC endpoint to allow traffic to reach the global AWS X-Ray daemon on TCP port 2000.

Enable AWS X-Ray. Configure Amazon CloudWatch to push logs to X-Ray.

Add the AWS X-Ray software development kit (SDK) to the microservices. Use X-Ray to trace requests that each microservice makes.

Set up Amazon CloudWatch metric streams to collect streaming data from the microservices.

Question 103

A company requires that all applications running on Amazon EC2 use 1AM roles to gam access to AWS services. A developer is modifying an application that currently relies on 1AM user access keys stored in environment variables to access Amazon DynamoDB tables using boto, the AWS SDK for Python.

The developer associated a role with the same permissions as the 1AM user to the EC2 instance, then deleted the 1AM user. When the application was restarted, the AWS

Access Denied Exception messages started appearing in the application logs. The developer was able to use their personal account on the server to run DynamoDB API commands using the AWS CLI.

What is the MOST likely cause of the exception?

Options:

1AM policies might take a few minutes to propagate to resources.

Disabled environment variable credentials are still being used by the application.

The AWS SDK does not support credentials obtained using an instance role.

The instance's security group does not allow access to http://169.254.169.254.
