Topic 1 Question 111
A company recently migrated a message processing system to AWS. The system receives messages into an ActiveMQ queue running on an Amazon EC2 instance. Messages are processed by a consumer application running on Amazon EC2. The consumer application processes the messages and writes results to a MySQL database running on Amazon EC2. The company wants this application to be highly available with low operational complexity. Which architecture offers the HIGHEST availability?
- Add a second ActiveMQ server to another Availability Zone. Add an additional consumer EC2 instance in another Availability Zone. Replicate the MySQL database to another Availability Zone.
- Use Amazon MQ with active/standby brokers configured across two Availability Zones. Add an additional consumer EC2 instance in another Availability Zone. Replicate the MySQL database to another Availability Zone.
- Use Amazon MQ with active/standby brokers configured across two Availability Zones. Add an additional consumer EC2 instance in another Availability Zone. Use Amazon RDS for MySQL with Multi-AZ enabled.
- Use Amazon MQ with active/standby brokers configured across two Availability Zones. Add an Auto Scaling group for the consumer EC2 instances across two Availability Zones. Use Amazon RDS for MySQL with Multi-AZ enabled.

- 正解だと思う選択肢: D
  Answer is D as the "HIGHEST available" and less "operational complex" The "Amazon RDS for MySQL with Multi-AZ enabled" option excludes A and B The "Auto Scaling group" is more available and reduces operational complexity in case of incidents (as remediation it is automated) than just adding one more instance. This excludes C.
  
  C and D to choose from based on D over C since is configured

  Option D offers the highest availability because it addresses all potential points of failure in the system:
  
  Amazon MQ with active/standby brokers configured across two Availability Zones ensures that the message queue is available even if one Availability Zone experiences an outage.
  
  An Auto Scaling group for the consumer EC2 instances across two Availability Zones ensures that the consumer application is able to continue processing messages even if one Availability Zone experiences an outage.
  
  Amazon RDS for MySQL with Multi-AZ enabled ensures that the database is available even if one Availability Zone experiences an outage.
