Q1.  A company uses Amazon EC2 instances and stores data on Amazon Elastic Block Store (Amazon EBS) volumes. The company must ensure that all data is encrypted at rest by using AWS Key Management Service (AWS KMS). The company must be able to control rotation of the encryption keys.

Which solution will meet these requirements with the LEAST operational overhead?

• A. Create a customer managed key. Use the key to encrypt the EBS volumes.

• B. Use an AWS managed key to encrypt the EBS volumes. Use the key to configure automatic key rotation.

• C. Create an external KMS key with imported key material. Use the key to encrypt the EBS volumes.

• D. Use an AWS owned key to encrypt the EBS volumes.

Answer(s):

Option A is CORRECT because creating a customer managed key in AWS Key Management Service (AWS KMS) and using this key to encrypt Amazon EBS volumes provides the necessary control over the encryption key, including its rotation policy. AWS KMS allows for the creation of customer managed keys with configurable rotation settings, enabling the company to control the rotation of their encryption keys. This approach meets the requirements for encryption at rest and key rotation with minimal operational overhead, as the rotation can be automated within the AWS KMS service.

Option B is INCORRECT because while AWS managed keys can be used to encrypt EBS volumes and these keys are automatically rotated by AWS every three years, the customer does not have control over the rotation frequency or the ability to manually rotate these keys. Thus, this option does not fully meet the requirement of being able to control the rotation of the encryption keys.

Option C is INCORRECT because using an external KMS key with imported key material adds complexity and operational overhead. While this approach provides the highest level of control over the encryption keys, including their creation, management, and rotation outside of AWS, it requires the company to handle the key material securely and to manually rotate and re-import new key material. This increases the operational effort compared to using AWS KMS-managed keys.

Option D is INCORRECT because AWS owned keys, while used for encrypting EBS volumes, do not provide the company with any ability to manage or rotate the keys. AWS owned keys are managed and rotated by AWS, and customers have no visibility or control over these keys. This option does not meet the requirement of being able to control the rotation of the encryption keys.

Q2.A company is migrating its multi-tier on-premises application to AWS. The application consists of a single-node MySQL database and a multi-node web tier. The company must minimize changes to the application during the migration. The company wants to improve application resiliency after the migration.

Which combination of steps will meet these requirements? (Choose two.)

• A. Migrate the web tier to Amazon EC2 instances in an Auto Scaling group behind an Application Load Balancer.

• B. Migrate the database to Amazon EC2 instances in an Auto Scaling group behind a Network Load Balancer.

• C. Migrate the database to an Amazon RDS Multi-AZ deployment.

• D. Migrate the web tier to an AWS Lambda function.

• E. Migrate the database to an Amazon DynamoDB table.

Option A is CORRECT. First, it involves moving the web tier to Amazon EC2 instances. These instances are placed in an Auto Scaling group. This setup adjusts capacity automatically, ensuring steady performance. An Application Load Balancer is used to distribute incoming traffic. Traffic is spread across multiple EC2 instances in different Availability Zones. This enhances the fault tolerance of the application.

Option C is CORRECT due to its approach to database resiliency. It suggests migrating the MySQL database to Amazon RDS with a Multi-AZ deployment. RDS Multi-AZ deployments offer high availability and failover support. This is crucial for production databases. Amazon RDS manages a synchronous standby replica in another Availability Zone. During maintenance or outages, RDS automatically fails over to this standby. This minimizes downtime without manual intervention.

Option B is INCORRECT for a database setup. Auto Scaling groups and Network Load Balancers are not typically used for databases like MySQL. These databases require consistent storage and specialized scaling. Such a setup is more complex and less suitable for relational databases.

Option D is INCORRECT due to the nature of AWS Lambda. Migrating to Lambda involves significant architectural changes. Lambda runs code in response to events and manages resources automatically. However, transitioning a traditional web application to serverless is a major change. It would not be a minimal alteration.

Option E is INCORRECT because it involves a significant platform shift. Amazon DynamoDB is a NoSQL database service. Moving from MySQL to DynamoDB requires changes in the data access layer. The data model and query capabilities of DynamoDB are different from MySQL. This migration would not align with the goal of minimal application changes.
