Which S3 storage solution archives private documents at the lowest cost?
Determine a cost optimization strategy to meet solution goals and objectives.
Determine security controls based on requirements.
Answer
Correct answer: A — Use S3 One Zone-IA as the default storage class for the private archive bucket accessed through the S3 interface endpoint.
A company is planning to store a large number of archived documents and make the documents available to employees through the corporate intranet. Employees will access the system by connecting through a client VPN service that is attached to a VPC. The data must not be accessible to the public. The documents that the company is storing are copies of data that is held on physical media elsewhere. The number of requests will be low. Availability and speed of retrieval are not concerns of the company. Which solution will meet these requirements at the LOWEST cost?
Community Insight
The exam tests choosing an S3 storage class by access pattern, cost, and retrieval latency, not by picking the absolute cheapest storage tier; the trap is Glacier Deep Archive's restore workflow and website-hosting incompatibility.
This SAP-C02 scenario asks for the lowest-cost way to serve archived documents privately to employees through a VPC-attached client VPN. S3 One Zone-IA is the correct answer because the archive is a copy, requests are low, and one-zone durability is acceptable when speed and availability are not concerns.
Many learners choose Glacier Deep Archive (D) because it has the lowest per-GB storage price, overlooking restore delays, retrieval costs, and the fact that archived objects cannot be served directly by S3 website hosting.

S3 website endpoints support publicly accessible content. Website hosting commonly requires disabling S3 Block Public Access and granting public s3:GetObject permissions. An S3 interface endpoint does not turn the S3 website endpoint into a private endpoint; website endpoints are not accessed through AWS PrivateLink interface endpoints. https://docs.aws.amazon.com/AmazonS3/latest/userguide/WebsiteEndpoints.html

D. S3 Glacier Deep Archive + Interface Endpoint Glacier Deep Archive is the cheapest storage class in AWS for long-term archival. Retrieval is slow (hours), but that’s acceptable here. Private access via S3 interface endpoint ensures no public exposure. Website hosting is unnecessary but can be ignored if bucket policy restricts access. Cost: Lowest among all options → Correct choice.

D. Is the correct answer. The reason for configuring website hosting is so that DNS can be used with the intranet domain name, not to actually serve content as a website. This allows people to request the document and return when it is restored. It is by far the most cost effective option and frankly, whenever a question uses the terms "no concern on retrieval time," Glacier is the answer they are going for.

Its really interesting reading all of these answers. I honestly think this question is messed up or intended to really trick you.

I tried it out. I uploaded identical HTML files to an S3 bucket, specifying each storage class. When using the Glacier storage class, I received a 403 error when accessing the web. Therefore, the answer is the One Zone-Infrequent Access (S3 One Zone-IA) storage class, and option A is correct.

Glacier and Glacier Deep Archive objects are not immediately readable. You must restore them before GET works. Hitting them via a website endpoint will return 403 until a restore completes.

Although option D mentions configuring the S3 bucket for website hosting, the key part is restricting access via an S3 VPC endpoint, ensuring data is not publicly exposed. The website hosting configuration can be ignored or omitted if only intranet access is required, or simply means enabling bucket policies for the intranet use

Selected: D
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.

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.

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.

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.

S3 interface endpoint doesn't support web hosting. The question does not say large files, but large number of archived documents, which could be small-sized. Hence EFS OZ-IA (being cheaper than SC1) could be the right answer.

While D is most probably the cheapest solution. When you try to download an object in deep archive you get a warning that it is not possible. You need to retrieve it: got to actions and restore which will need at least 12 hours for deep archive. Only after that you can access the document. The answer D says enable webhosting: thats afaik not going to work but users will end up in above mentioned warning. Therefore we need to go for A which is not as cheap but users can access the documents.

Given the requirements and the need for the lowest cost solution, the best option would be: A. Create an Amazon S3 bucket. Configure the S3 bucket to use the S3 One Zone-Infrequent Access (S3 One Zone-IA) storage class as default. Configure the S3 bucket for website hosting. Create an S3 interface endpoint. Configure the S3 bucket to allow access only through that endpoint. Options B and C involve launching EC2 instances which would add unnecessary complexity and cost since the company's priority is to minimize costs. Additionally, option D involves using the S3 Glacier Deep Archive storage class which is intended for long-term archival data and has longer retrieval times, making it less suitable for the given requirements.

You cannot have a website on Glacier, so D is clearly wrong. To retrieve documents from Glacier you need to first call 'restore' on it. The object becomes available after considerable amount of time in standard storage class a for a limited duration. This wouldn't work on a static website. I suppose technically you could build a non-static application to manage restoring files for users, but it's awkward, and the solution would likely cost more due to development costs. Glacier's purpose is to store data that you never want to see again, but there is a 0.001% chance you might actually need it at some point. It is comparable to tape storage. ChatGPT cannot answer these questions accurately because it is unable to reason.

The cheapest storage tier in Amazon S3 that can be used for static web hosting is the Amazon S3 Standard - Infrequent Access (S3 Standard-IA).

If the company needs to access these documents occasionally and can tolerate several hours of retrieval time, Option D (Glacier Deep Archive) would be the most cost-effective solution. However, if the company requires faster access to these documents (even if infrequently), Option A (S3 One Zone-IA) would be a better choice, balancing cost with the need for more immediate access. Since the original statement indicates that "availability and speed of retrieval are not concerns," Option D (Glacier Deep Archive) aligns more closely with these stipulations, offering the lowest cost solution at the expense of longer retrieval times. However, if the retrieval time becomes a concern at any point, switching to S3 One Zone-IA (Option A) could provide a middle ground between cost and accessibility.

Nunca se menciono un sitio web, se dijo "intranet" a través de la VPN, por lo que no es necesario una web estaticas en el bucket. Elijo la opción D

Option D: Create an Amazon S3 bucket. Configure the S3 bucket to use the S3 Glacier Deep Archive storage class as default. Configure the S3 bucket for website hosting. Create an S3 interface endpoint. Configure the S3 bucket to allow access only through that endpoint. This option would be less expensive than using other S3 storage classes, but it would still be more expensive than using S3 One Zone-IA storage. Additionally, using the S3 Glacier Deep Archive storage class would make retrieval of the documents slow and expensive, which does not meet the company's requirements. Therefore, this option is not the best fit for the company's requirements.Hence A

When tackling AWS questions, always note the key requirement which is the LOWEST cost. It even says number of requests is low, availability and speed are not of concern. Also don't make assumptions of the methods retrieval, it can always be a frontend to trigger restore and then once restore is complete, notify user to download. Frontend is not the main point of the question, here we want to provide solution for storage archival at CHEAPEST cost.

Within a single bucket, the object for website hosting is not necessarily a Glacier Deep Archive storage class. Since the purpose is to store archived documents, you can assume long-term storage.

This solution provides cost-effective storage for the archived documents using the S3 One Zone-Infrequent Access (S3 One Zone-IA) storage class, which is the lowest cost storage option for infrequently accessed data in a single availability zone. Hosting the S3 bucket as a website enables easy access to the documents through the intranet, and creating an S3 interface endpoint ensures that access is only possible through the VPN attached to the VPC. Additionally, S3 provides built-in security features, such as bucket policies and access control lists (ACLs), to control access to the data.

I'm on the fence on this question, Option A is offering a Single AZ S3 bucket with infrequent access that has the feature to enable web hosting. I can't find a web hosting feature with any of the archive classes unless the archive is restored and transitioned back to the standard class.

Confused by why everyone thinks it's D, reading the doc it says the use case and the minimum archive period is 90 days. https://docs.aws.amazon.com/AmazonS3/latest/userguide/restoring-objects.html Number of days you plan to keep objects archived – S3 Glacier Flexible Retrieval and S3 Glacier Deep Archive are long-term archival solutions. The minimal storage duration period is 90 days for the S3 Glacier Flexible Retrieval storage class and 180 days for S3 Glacier Deep Archive. Deleting data that is archived to Amazon S3 Glacier doesn't incur charges if the objects you delete are archived for more than the minimal storage duration period. If you delete or overwrite an archived object within the minimal duration period, Amazon S3 charges a prorated early deletion fee. For information about the early deletion fee, see the

I'm really unsure on this one. I can't find a definitive answer whether you can use glacier to host web content. It would make sense you can't because you need to restore the data before retrieving it, but theoretically it could be possible with application logic. This question feels like its a gotcha that is using Glacier as a red herring for CHEAPEST option but really wants you to use One Zone IA.

Selected: D
The S3 Glacier Deep Archive storage class is the lowest-cost storage class offered by Amazon S3, and it is designed for archival data that is accessed infrequently and for which retrieval time of several hours is acceptable. S3 interface endpoint for the VPC ensures that access to the bucket is only from resources within the VPC and this will meet the requirement of not being accessible to the public. And also, S3 bucket can be configured for website hosting, and this will allow employees to access the documents through the corporate intranet. Using an EC2 instance and a file system or block store would be more expensive and unnecessary because the number of requests to the data will be low and availability and speed of retrieval are not concerns. Additionally, using Amazon S3 bucket will provide durability, scalability and availability of data.

Answer A. You cannot host a website from glacier: Glacier needs an other bucket to restore the requested objects, and a lifetime. You cannot achieve this with the static s3 hosting (initiate restore). Yes, it will be the cheapest solution, but does not work.

Nevermind, I go for D. It should be technically possible - and mostly dependent on the intranet web application logic - It could present users with the ability to start file retrieval, for then to later access the data.

Why the Answer Is Correct
Option A is the best fit because S3 One Zone-IA is designed for infrequently accessed, re-creatable data that does not need multi-AZ resilience. The scenario explicitly says the documents are copies of data held on physical media elsewhere, requests are low, and availability/speed are not concerns, so paying for Standard or multi-AZ storage is unnecessary. S3 also avoids running and patching an EC2 web server plus EFS/EBS, and the interface endpoint gives private access from the VPC-attached client VPN without exposing the bucket publicly. Although the website-hosting wording is technically awkward with an interface endpoint, A still uses the correct low-cost storage class and private S3 access pattern.Why the Other Options Are Wrong
Option B uses EFS One Zone-IA, which is far more expensive per GB than S3 One Zone-IA and requires an EC2 server, so it cannot be lowest cost. Option C uses EBS sc1 on a single EC2 instance; sc1 is cheap per GB but still needs an EC2 server, is limited by volume size, and does not provide S3's durable object-storage model. Option D uses Glacier Deep Archive, whose per-GB price is lower, but objects must be restored before they can be read; S3 website hosting cannot serve an unrestored Deep Archive object, and a restore/notification workflow would add complexity and retrieval costs. The exam's "lowest cost" means the lowest total solution that actually makes documents available, not the cheapest storage line item.Community Comment Notes
Learners split mainly between A and D. tman22 initially noted that "Glacier Deep Archive can't be used for web hosting," while also considering D if the intranet triggers restores; a54b16f argued that using Glacier would require a separate restore application, saying you "Need to develop a whole new application" to request unarchiving. Maria2023 and Dimidrol reinforced A from the website-hosting angle, with Dimidrol reporting an actual "operation invalid for object storage class" error when serving archived objects. OnePunchExam's D-leaning point is fair that the frontend could handle restores, but the question gives no such workflow, so A is the safer exam answer for immediate, private, low-cost access.Official Reference
Exam Strategy
When an SAP-C02 question says "lowest cost," compare total cost, not just storage price: Glacier Deep Archive adds restore latency and retrieval fees. Also separate archive storage from the serving path: if users must browse documents through an intranet, the storage class must allow on-demand reads or include a restore workflow.
Frequently Asked Questions
Why is S3 Glacier Deep Archive not the lowest-cost answer here?
Its per-GB storage is cheaper, but restoring archived objects takes hours and adds retrieval/request costs; without a restore workflow the intranet cannot serve them directly.
Why does S3 One Zone-IA fit data copied from physical media?
Because the archive is a secondary copy, losing one Availability Zone does not lose the only copy, and One Zone-IA costs less than Standard-IA.
