Free AWS DVA-C02 Actual Exam Questions - Question 1 Discussion
a network shared folder as a centralized configuration repository to store configuration files in .xml
format. The company is migrating the application to Amazon EC2 instances. As part of the migration
to AWS, a developer must identify a solution that provides high availability for the repository.
Which solution will meet this requirement MOST cost-effectively?
It’s C because using S3 directly with the AWS SDK gives you built-in durability and availability without the complexity of mounting or managing file systems. Mounting S3 (D) can cause performance issues and isn’t fully native.
Maybe D works best since mounting the S3 bucket keeps the shared folder approach and S3 offers built-in high availability, unlike EBS or instance store which are tied to single instances.
A - EBS is single-instance and doesn’t provide high availability by itself.
Option D seems better than some others because mounting S3 as a local volume keeps the shared folder concept intact without changing the app drastically. Unlike option A, you avoid managing EBS volumes and a file share yourself, which can get expensive and complex for high availability. Option B is risky since instance store volumes aren’t durable and won’t survive instance failures, so it’s not really HA. Option C would require rewriting code to use the AWS SDK, which could be more work and riskier. So D offers a nice balance of cost, availability, and minimal app changes.
Is the app already set up to use ECS task definitions or Parameter Store?
