A - Glacier Deep Archive can't be used for web hosting, regardless if the company says retrieval time is no concern.

A is correct. HA is not required here. D use Glacier deep archive that need hours to access that will cause time out for web

All components work, supports website hosting, low cost

A questão não aborda hospedagem. A intranet já existe e fará a consulta no S3. Geralmente armazenamento MENOR custo e que não tenha tempo de recuperação a resposta é o Glacier.

"speed of retrieval does not matter" = s3 glacier deep archive. Although S3 Glacier Deep Archive can't be used for website hosting, you also don't need it because you're accessing the documents via the S3 interface endpoint via the intranet.

Why D is correct: S3 Glacier Deep Archive is the lowest-cost storage class designed for rarely accessed data, which fits the use case perfectly. Access through an S3 interface endpoint ensures that data is not exposed to the public internet, meeting the security requirement. Hosting the files through S3 website hosting (even though retrieval is slow) provides a simple mechanism for access via intranet (assuming internal DNS can resolve the endpoint). There’s no need to run or manage EC2 instances, no web servers, and no block or file storage, reducing both operational overhead and cost.

A - Glacier Deep Archive can't be used for web hosting, regardless if the company says retrieval time is no concern.

Why are people bringing in webhosting here, it said it would be accessible over corporate intranet. So their they can implement to raise a request for accessing any archive and once it's ready they can share a link that can be accessed over the intranet. So D is the right answer.

S3 Glacier Deep Archive will be the lowest cost.

The question does not require website hosting. Its focus is on securely storing documents so employees can access them via VPN without exposing them to the public Internet. So Glacier Deep Archive is more cost-saving

Buckets do not have a storage class... objects do! You can enable web hosting on any bucket and retrieve the objects (when available) over HTTP, whether the objects are available instantly or not that is another question. For glacier, you will have to request a restore and wait but when the object is eventually ready, you can download it directly over HTTP. So, the answer is D.

S3 glacier can be used for hosting as it requires additional steps to unarchive objects!

No, Amazon S3 Glacier Deep Archive cannot be used for web hosting. Reasons: Glacier Deep Archive is not designed for real-time access: Glacier Deep Archive is intended for long-term, infrequently accessed archival data. Retrieval times can range from 12 hours to 48 hours, making it unsuitable for serving content dynamically or in real-time through a website. No direct web hosting capabilities: S3 web hosting requires immediate availability of objects stored in the bucket. S3 Glacier Deep Archive is designed for delayed access, so objects stored in this class cannot be served directly. Storage class retrieval process: Objects stored in Glacier or Glacier Deep Archive require a retrieval job to be initiated before they are available for access. This process is asynchronous and incompatible with the demands of a web-hosting use case.

keywords: 'Archive documents, low requests, low availability and speed, LOWEST cost' = S3 Glacier Deep Archive

only A & D make sense, and since website hosting is also a requirement, I'll go with A.

The requirements are to store a large number of archived documents that are not publicly accessible, and make them available to employees through a corporate intranet. As the number of requests is low and speed of retrieval is not a concern, we can use the low-cost S3 One Zone-Infrequent Access (S3 One Zone-IA) storage class. We can configure the S3 bucket for website hosting and create an S3 interface endpoint to allow access to the documents only through the corporate intranet. This solution is the lowest cost as it eliminates the need to launch and manage EC2 instances. Option B and C involve launching an EC2 instance which increases the operational overhead and is more expensive than using S3. Also, EFS One Zone-IA storage class is not recommended for storing large files. Option D involves using the S3 Glacier Deep Archive storage class which is intended for long-term archival storage of data and not suitable for retrieving data frequently.

https://docs.aws.amazon.com/AmazonS3/latest/userguide/storage-class-intro.html Store large number of archived docs, and available through corp intranet. Copies of data held on physical media elsewhere (could be re-created). Requests low (but it doesn't say RARE so think monthly/quarterly). "AVAILABILITY" and speed of retrieval are not concerns. It is A, yes Glacier is "cheaper", but I have to leave the archives for at least 180 days, would be available on corp intranet and it is more cost-effective if I want to migrate the data to Glacier if I monitor use and see it is "rarely" touched and know I have to hold it due to regulatory for at minimal 180 days.
