Zorluk: KolayAWS Storage Services

A company is launching a database on a single Amazon Elastic Compute Cloud (Amazon EC2) instance. The database requires a persistent block storage volume that behaves like a physical hard drive and retains its data even if the EC2 instance is stopped or restarted. Which AWS storage service best meets these requirements?

  1. Amazon Elastic Block Store (Amazon EBS)Cevap
  2. B
    Amazon Simple Storage Service (Amazon S3)
  3. C
    Amazon Elastic File System (Amazon EFS)
  4. D
    Amazon EC2 Instance Store

Cevap

Amazon Elastic Block Store (Amazon EBS)
The correct service is Amazon Elastic Block Store (Amazon EBS) because it provides persistent block storage volumes that behave like physical hard drives. It can be easily attached to a single Amazon EC2 instance and keeps data intact even when the instance is stopped or restarted.

Adım Adım Çözüm

1
Analyze the requirements in the scenario.
The requirements are: block storage, persistent (must survive instance stop/restart), and attached to a single EC2 instance.
This helps filter out services that do not offer block storage or persist data.
2
Evaluate the available storage options against the requirements.
Amazon EBS offers persistent block storage that behaves like a physical drive. Amazon S3 is object storage, Amazon EFS is shared file storage, and Amazon EC2 Instance Store is temporary storage.
Choosing the service that matches persistent block storage leads to the correct answer.
