Zorluk: OrtaAWS Storage Services

A company is developing a hybrid web application on Amazon EC2. The application has two distinct storage requirements. First, it needs a storage solution to host static user profile images that must be highly durable, scalable, and directly accessible via public web URLs. Second, it needs a persistent, low-latency block storage volume for database logs that is dedicated to a single EC2 instance and must retain data when the instance is stopped. Which two AWS storage services should the company select to meet these requirements? (Select TWO)

  1. Amazon Simple Storage Service (Amazon S3) to host the static user profile imagesCevap
  2. Amazon Elastic Block Store (Amazon EBS) to store the persistent database logsCevap
  3. C
    Amazon Elastic File System (Amazon EFS) to store the low-latency database logs
  4. D
    Amazon EC2 Instance Store to store the database logs that must persist when stopped
  5. E
    AWS Storage Gateway to host the static user profile images for web access

Cevap

Amazon Simple Storage Service (Amazon S3) to host the static user profile images, and Amazon Elastic Block Store (Amazon EBS) to store the persistent database logs
The correct options are the ones recommending Amazon Simple Storage Service (Amazon S3) and Amazon Elastic Block Store (Amazon EBS). Amazon S3 is the ideal solution for storing and retrieving static files like user profile images due to its high durability, scalability, and ability to serve objects over public URLs. Amazon EBS is the correct choice for the database logs because it provides low-latency, persistent block storage volumes that are dedicated to a single EC2 instance and retain data even if the instance is stopped.

Adım Adım Çözüm

1
Analyze the first requirement: highly durable, scalable storage for static images accessible via URLs.
Identify that Amazon S3 is the optimal choice because it is a highly durable object storage service that natively supports public HTTP/HTTPS URL access for static media.
This matches the characteristics of object storage rather than block or file storage.
2
Analyze the second requirement: persistent, low-latency block storage dedicated to a single EC2 instance that retains data when stopped.
Identify that Amazon EBS provides persistent block-level storage volumes that can be attached to a single EC2 instance and preserve data independently of the instance lifespan.
This matches the characteristics of persistent block storage rather than ephemeral storage (Instance Store) or shared file storage (EFS).
