Question
A company wants to store its files in the AWS Cloud. Users need to be able to download these files directly using a public URL.
Which AWS service or feature will meet this requirement?
A. Amazon Redshift
B. Amazon Elastic Block Store (Amazon EBS)
C. Amazon Elastic File System (Amazon EFS)
D. Amazon S3
Answer
D. Amazon S3
Explanation
Amazon Simple Storage Service (Amazon S3) is the most suitable AWS service for storing files and allowing users to download them directly using a public URL. S3 is an object storage service that offers industry-leading scalability, data availability, security, and performance.
Key reasons why Amazon S3 is the best choice:
- Public Access: S3 buckets can be configured to allow public access to objects, enabling users to download files directly using a unique URL for each object. This eliminates the need for a separate web server or application to serve the files.
- Scalability: S3 is designed to scale seamlessly, allowing companies to store and retrieve any amount of data from anywhere on the web. There are no storage limits, and the service automatically scales to accommodate growth.
- Durability and Availability: S3 is built for 99.999999999% (11 9’s) of durability and 99.99% availability, ensuring that files are always accessible when needed.
- Cost-effective: With S3, companies only pay for the storage they use, and there are no minimum fees or setup costs. This makes it an affordable solution for storing and sharing files.
The other options are not suitable for this use case:
- Amazon Redshift (A) is a data warehousing service used for analytical workloads and is not designed for serving files to users.
- Amazon Elastic Block Store (EBS) (B) provides block-level storage volumes for use with Amazon EC2 instances and is not directly accessible via public URLs.
- Amazon Elastic File System (EFS) (C) is a scalable file storage service for use with Amazon EC2 instances, but it does not provide direct public access to files via URLs.
In summary, Amazon S3 is the best choice for storing files and allowing users to download them directly using public URLs, making it the correct answer for this AWS Certified Cloud Practitioner Exam question.
