Zorluk: ZorAWS Storage Services

A company is building a high-performance computing (HPC) application on AWS that runs across a fleet of Linux-based Amazon EC2 instances. The application has two distinct storage requirements: first, it requires high-throughput, lowest-latency block storage for storing temporary scratch files that are discarded when the instances terminate; second, it requires a shared, POSIX-compliant directory structure that all EC2 instances in the fleet can mount simultaneously to read and write application configuration files. Which AWS storage solutions should the company select to meet these requirements? (Select TWO.)

  1. Amazon EC2 Instance Store to serve as the low-latency block storage for temporary scratch filesCevap
  2. Amazon Elastic File System (Amazon EFS) to serve as the shared, POSIX-compliant file system for the fleetCevap
  3. C
    Amazon Elastic Block Store (Amazon EBS) gp3 volumes to serve as the shared, POSIX-compliant file system for the fleet
  4. D
    Amazon Simple Storage Service (Amazon S3) Standard to serve as the low-latency block storage for temporary scratch files
  5. E
    Amazon S3 Glacier Deep Archive to serve as the shared, POSIX-compliant file system for the fleet

Cevap

The correct answers are Amazon EC2 Instance Store to serve as the low-latency block storage for temporary scratch files, and Amazon Elastic File System (Amazon EFS) to serve as the shared, POSIX-compliant file system for the fleet.
The correct options are Amazon EC2 Instance Store and Amazon Elastic File System (Amazon EFS). Amazon EC2 Instance Store provides temporary, low-latency block storage directly attached to the host instance, making it ideal for scratch space. Amazon Elastic File System (Amazon EFS) offers a shared, POSIX-compliant file system that allows multiple EC2 instances to mount and access it simultaneously.

Adım Adım Çözüm

1
Analyze the first requirement: high-performance, low-latency temporary block storage for scratch files that are deleted upon instance termination.
Identify Amazon EC2 Instance Store as the service providing temporary, host-attached block storage with the lowest latency.
Instance Store is specifically designed for temporary workloads where data persistence is not required beyond the instance lifespan.
2
Analyze the second requirement: a shared, POSIX-compliant directory structure that multiple EC2 instances can mount simultaneously.
Identify Amazon Elastic File System (Amazon EFS) as the service providing a scalable, shared file system supporting the NFS protocol.
EFS is a managed, shared file system that allows thousands of EC2 instances to access the same directory path concurrently, complying with POSIX standards.
