[All AWS Certified Solutions Architect - Associate SAA-C02 Questions]

A company is creating a new application that will store a large amount of data. The data will be analyzed hourly and modified by several Amazon EC2 Linux instances that are deployed across multiple Availability Zones. The application team believes the amount of space needed will continue to grow for the next 6 months.
Which set of actions should a solutions architect take to support these needs?

  • A. Store the data in an Amazon Elastic Block Store (Amazon EBS) volume. Mount the EBS volume on the application instances.
  • B. Store the data in an Amazon Elastic File System (Amazon EFS) file system. Mount the file system on the application instances.
  • C. Store the data in Amazon S3 Glacier. Update the S3 Glacier vault policy to allow access to the application instances.
  • D. Store the data in an Amazon Elastic Block Store (Amazon EBS) Provisioned IOPS volume shared between the application instances.

B is Correct, A doesn't make sense because EBS must be in the same AZ as the EC2 instance.But here he is talking about Multi-AZ instances.

As they discussed Multiple AZ. SO EBS is out (A and D). So the correct option is EFS (Hints EC2 Linux Instance )

B is correct. EBS with io1/io2 has multi attach feature for use by multiple ec2 instances. But it cannot span AZ.Also it is provisioned capacity,not flexible (EFS scales as per usage,pay for what is actually stored)

B is correct. EFS can be shared between several Multi-AZ EC2 instances. A is wrong because EBS volume can not be mounted on multiple application instances.
