An IT administrator is designing a storage architecture for a corporate application on AWS. The application has two key requirements:
1. It needs a persistent block storage volume to serve as the boot drive for a single Amazon EC2 instance.
2. It needs a shared file system that can be accessed and updated simultaneously by multiple EC2 instances using the Network File System (NFS) protocol.
Which two AWS storage services should the administrator select? (Select TWO.)
- Amazon Elastic Block Store (Amazon EBS)Cevap
- Amazon Elastic File System (Amazon EFS)Cevap
- CAmazon Simple Storage Service (Amazon S3)
- DAmazon EC2 Instance Store
- EAWS Storage Gateway
Cevap
Amazon Elastic Block Store (Amazon EBS) and Amazon Elastic File System (Amazon EFS)
Amazon Elastic Block Store (Amazon EBS) provides persistent, low-latency block storage volumes that are designed to be attached to a single EC2 instance, making it the ideal choice for an instance boot volume. Amazon Elastic File System (Amazon EFS) provides a fully managed shared file system that supports the Network File System (NFS) protocol, allowing hundreds of EC2 instances to mount and access the storage concurrently.

Anahtar Kavram
AWS storage services differ by their architecture (block vs. file vs. object) and access patterns (single instance vs. multi-instance concurrent access).
