Which statement or statements are TRUE about Amazon EBS volumes and Amazon EFS file systems?
A. EBS volumes store data within a single Availability Zone. Amazon EFS file systems store data across multiple Availability Zones.
B. EBS volumes store data across multiple Availability Zones. Amazon EFS file systems store data within a single Availability Zone.
C. EBS volumes and Amazon EFS file systems both store data within a single Availability Zone.
D. EBS volumes and Amazon EFS file systems both store data across multiple Availability Zones.

Answer

The correct answer is:

A. EBS volumes store data within a single Availability Zone. Amazon EFS file systems store data across multiple Availability Zones.

An EBS volume must be located in the same Availability Zone as the Amazon EC2 instance to which it is attached.
Data in an Amazon EFS file system can be accessed concurrently from all the Availability Zones in the Region where the file system is located.


Which Amazon S3 storage classes are optimized for archival data? (Select TWO.)
A. S3 Standard
B. S3 Glacier
C. S3 Intelligent-Tiering
D. S3 Standard-IA
E. S3 Glacier Deep Archive

Answer

The correct two answers are:

B. S3 Glacier
E. S3 Glacier Deep Archive


Objects stored in the S3 Glacier storage class can be retrieved within a few minutes to a few hours. By comparison, objects that are stored in the S3 Glacier Deep Archive storage class can be retrieved within 12 hours.

The other response options are incorrect because:

A. S3 Standard is a storage class that is ideal for frequently accessed data, not archival data.

C. S3 Intelligent-Tiering monitors access patterns of objects and automatically moves them between the S3 Standard and S3 Standard-IA storage classes. It is not designed for archival data.

D. S3 Standard-IA is ideal for data that is infrequently accessed but requires high availability when needed.
