Topic 1 Question 274
A company runs an application on Amazon EC2 instances. The company needs to implement a disaster recovery (DR) solution for the application. The DR solution needs to have a recovery time objective (RTO) of less than 4 hours. The DR solution also needs to use the fewest possible AWS resources during normal operations.
Which solution will meet these requirements in the MOST operationally efficient way?
Create Amazon Machine Images (AMIs) to back up the EC2 instances. Copy the AMIs to a secondary AWS Region. Automate infrastructure deployment in the secondary Region by using AWS Lambda and custom scripts.
Create Amazon Machine Images (AMIs) to back up the EC2 instances. Copy the AMIs to a secondary AWS Region. Automate infrastructure deployment in the secondary Region by using AWS CloudFormation.
Launch EC2 instances in a secondary AWS Region. Keep the EC2 instances in the secondary Region active at all times.
Launch EC2 instances in a secondary Availability Zone. Keep the EC2 instances in the secondary Availability Zone active at all times.

Guys, sorry but I don't really have time to deepdive as my exam is soon. Based on chatGPT and my previous study the answer should be B "Create Amazon Machine Images (AMIs) to back up the EC2 instances. Copy the AMIs to a secondary AWS Region. Automate infrastructure deployment in the secondary Region by using AWS CloudFormation," would likely be the most suitable solution for the given requirements.
This option allows for the creation of Amazon Machine Images (AMIs) to back up the EC2 instances, which can then be copied to a secondary AWS region to provide disaster recovery capabilities. The infrastructure deployment in the secondary region can be automated using AWS CloudFormation, which can help to reduce the amount of time and resources needed for deployment and management.

Option B would be the most operationally efficient solution for implementing a DR solution for the application, meeting the requirement of an RTO of less than 4 hours and using the fewest possible AWS resources during normal operations.
By creating Amazon Machine Images (AMIs) to back up the EC2 instances and copying them to a secondary AWS Region, the company can ensure that they have a reliable backup in the event of a disaster. By using AWS CloudFormation to automate infrastructure deployment in the secondary Region, the company can minimize the amount of time and effort required to set up the DR solution.
