Exam question from Amazon's AWS Certified SysOps Administrator - Associate

Question #: 411
Topic #: 1

[All AWS Certified SysOps Administrator - Associate Questions]

A company recently deployed an application in production. The production environment currently runs on a single Amazon EC2 instance that hosts the application's web application and a MariaDB database. Company policy states that all IT production environments must be highly available.

What should a SysOps administrator do to meet this requirement?

A. Migrate the database from the EC2 instance to an Amazon RDS for MariaDB Multi-AZ DB instance. Run the application on EC2 instances that are in an Auto Scaling group that extends across multiple Availability Zones. Place the EC2 instances behind a load balancer.
B. Migrate the database from the EC2 instance to an Amazon RDS for MariaDB Multi-AZ DB instance. Use AWS Application Migration Service to convert the application into an AWS Lambda function. Specify the Multi-AZ option for the Lambda function.
C. Copy the database to a different EC2 instance in a different Availability Zone. Use AWS Backup to create Amazon Machine Images (AMIs) of the application EC2 instance and the database EC2 instance. Create an AWS Lambda function that performs health checks every minute. In case of failure, configure the Lambda function to launch a new EC2 instance from the AMIs that AWS Backup created.
D. Migrate the database to a different EC2 instance. Place the application EC2 instance in an Auto Scaling group that extends across multiple Availability Zones. Create an Amazon Machine Image (AMI) from the database EC2 instance. Use the AMI to launch a second database EC2 instance in a different Availability Zone. Put the second database EC2 instance in the stopped state. Use the second database EC2 instance as a standby.

This option meets the requirement of making the production environment highly available. Here's how: 1. Migrating the database to Amazon RDS for MariaDB Multi-AZ DB instance ensures that the database is highly available and fault-tolerant, as it is replicated across multiple Availability Zones. 2. Running the application on EC2 instances in an Auto Scaling group that extends across multiple Availability Zones ensures that the application is highly available, as instances can be automatically launched in different Availability Zones in case of a failure. 3. Placing the EC2 instances behind a load balancer distributes the incoming traffic across the instances, providing load balancing and high availability for the application.
