A software company is building a collaborative development environment on AWS. The architecture requires:
1. A shared directory structure accessible by multiple Amazon EC2 developer instances concurrently across multiple Availability Zones with standard file system semantics.
2. High-performance, persistent block storage dedicated to a database instance running on a single EC2 instance, where data must survive instance stop and start cycles.
Which TWO AWS storage services should the company select to meet these requirements? (Select TWO).
- Amazon Elastic File System (Amazon EFS)Answer
- Amazon Elastic Block Store (Amazon EBS)Answer
- CAmazon S3 Glacier Deep Archive
- DAmazon EC2 Instance Store
- EAWS Storage Gateway
Answer
Amazon Elastic File System (Amazon EFS) and Amazon Elastic Block Store (Amazon EBS)
Amazon Elastic File System (Amazon EFS) is correct because it offers a fully managed, shared file system that can be accessed by multiple EC2 instances simultaneously across different Availability Zones. Amazon Elastic Block Store (Amazon EBS) is correct because it provides persistent, block-level storage volumes for a single EC2 instance that retains data even when the instance is stopped.
Step-by-Step Solution
Key Concept
Distinguishing access patterns, persistence, and performance characteristics between AWS storage options like Amazon EFS (shared file system), Amazon EBS (persistent block storage), Amazon EC2 Instance Store (ephemeral block storage), and Amazon S3 Glacier (archival object storage).
