Zorluk: KolayHigh-Performing and Scalable Storage Solutions

A company is deploying a media processing application on a fleet of Amazon EC2 instances. The application requires a high-performance, shared storage solution that supports POSIX-compliant file operations and can be accessed concurrently by all instances. Which two AWS storage services should the company use to meet these requirements? (Select TWO.)

  2. Amazon FSx for NetApp ONTAPCevap
  3. C
    Amazon Elastic Block Store (Amazon EBS) gp3 volumes
  4. D
    Amazon S3 Standard-IA
  5. E
    Amazon EBS throughput optimized HDD (st1) volumes

Cevap

Amazon Elastic File System (Amazon EFS) and Amazon FSx for NetApp ONTAP
The correct options are the Elastic File System and FSx for NetApp ONTAP. Both are native AWS shared file systems that support POSIX-compliant file operations, allowing multiple EC2 instances to read and write to the same storage space concurrently.

Adım Adım Çözüm

1
Identify that the workload requires a shared, POSIX-compliant file system accessible by multiple EC2 instances concurrently.
Identified the requirement for native file storage rather than block or object storage.
This helps narrow down the choices to shared file systems like Amazon EFS and Amazon FSx.
2
Evaluate the block storage options (Amazon EBS gp3 and st1).
Determined that standard EBS volumes are block storage designed for single-instance attachment.
This rules out EBS options as they cannot natively act as shared, multi-instance file systems.
3
Evaluate the object storage option (Amazon S3 Standard-IA).
Determined that Amazon S3 is object storage and does not support POSIX-compliant file operations natively.
This rules out S3 for this active file system workload.
4
Select the correct file storage solutions.
Selected Amazon EFS and Amazon FSx for NetApp ONTAP.
Both services are designed to offer high-performing, POSIX-compliant, concurrent shared file access for EC2 instances.
