A. AWS Software Development Kit
B. AWS Management Console
C. AWS CodePipeline
D. AWS Config
Show Answer

The other options are management or governance tools, not mechanisms for in-code service access.
Question 353
A user needs a relational database but does not have the resources to manage the hardware, resiliency, and replication.
Which AWS service option meets the user's requirements?
A. Run MySQL on Amazon Elastic Container Service (Amazon ECS).
B. Run MySQL on Amazon EC2.
C. Choose Amazon RDS for MySQL.
D. Choose Amazon ElastiCache for Redis.
Show Answer
Correct Answer: C
Explanation: The requirement is for a relational database without managing hardware, resiliency, or replication. Amazon RDS for MySQL is a fully managed relational database service that handles provisioning, backups, patching, high availability, and replication. Running MySQL on EC2 or ECS still requires managing the database and infrastructure, and ElastiCache for Redis is not a relational database.

B. AWS Application Migration Service
C. AWS DataSync
D. AWS Database Migration Service (AWS DMS)
Show Answer

The other options focus on storage integration, file transfer, or full server/application rehosting rather than database migration.

Question 357
An Amazon EC2 instance previously used for development is inaccessible and no longer appears in the AWS Management Console.
Which AWS service should be used to determine what action made this EC2 instance inaccessible?
A. Amazon CloudWatch Logs
B. AWS Security Hub
C. Amazon Inspector
D. AWS CloudTraiI
Show Answer
Correct Answer: D
Explanation: AWS CloudTrail records API calls and account activity across AWS services. It allows you to see who performed actions on an EC2 instance (such as stop, terminate, or modify), when the action occurred, and from where. This makes CloudTrail the correct service to determine what action caused the EC2 instance to become inaccessible or disappear.

Which AWS service should the company use to meet these requirements?
A. Amazon DynamoDB

C. AWS Lambda
D. Amazon RDS
Show Answer
