Cost-Optimized Storage for AI Image Workloads
Short answer
C Move uploaded images to Amazon S3 One Zone-Infrequent Access (S3 One Zone-IA). Move premium user-generated AI images to S3 Standard. Move non-premium user-generated AI images to S3 Standard-Infrequent Access (S3 Standard-IA).
Question
Key Takeaways
Tests ability to select storage classes based on retrieval time constraints versus frequency; the trap is choosing Deep Archive for its low price despite violating the 6-hour download SLA.
This question evaluates the cost-effective storage of user-uploaded and generated images with varying access patterns, establishing S3 One Zone-IA as the optimal choice for infrequent training data.
Common mistake: Users often choose A because Glacier Deep Archive is the cheapest option, failing to account for the retrieval latency that exceeds the required service level.
Expert Analysis
Why the Answer Is Correct
S3 One Zone-IA is the correct choice because it offers the lowest cost for data accessed infrequently while providing immediate access upon request. The uploaded images are used only twice a year for training, fitting the 'infrequent' profile perfectly, and the requirement to run training implies a need for relatively quick access compared to cold storage options.
Why the Other Options Are Wrong
Option A uses S3 Glacier Deep Archive, which has retrieval times ranging from 12 hours to several days, making it impossible to meet the implicit need for timely model training preparation. Option B fails similarly by using Glacier Flexible Retrieval for all generated images, which would delay premium users who expect instant downloads. Option D also incorrectly places generated images in Glacier, causing unacceptable latency for frequent downloads.
Community Comment Notes
Many learners selected A because they focused solely on the absolute lowest price point without considering the operational requirements. As one commenter noted, "Deep Archive... can spend hours to retrieve each object," highlighting the critical constraint. Another user correctly pointed out that "For AI model training, you'd hate it if you must spend hundreds/thousands of hours before you can actually start training it," emphasizing why immediate access is non-negotiable for this workflow.
Exam Strategy
Always check retrieval time requirements before selecting the cheapest storage class. If the data needs to be available within minutes or hours, avoid Glacier Deep Archive and consider S3 Standard-IA or One Zone-IA.

dhewa 👍 7 Answered AThe company uses the user-uploaded images to run AI model training twice a year. So for this Deep Archive will be ncessary.

blehbleh 👍 5 Answered AThis is A. We care about cost effectiveness. In regards to images being used twice a year "For images accessed only twice a year, S3 Glacier Deep Archive would be the more cost-effective option compared to S3 One Zone Infrequent Access, as it is designed for extremely infrequent access and offers the lowest storage cost within AWS S3 storage classes; while S3 One Zone Infrequent Access is cheaper than standard Infrequent Access, it still might be slightly more expensive for data accessed as rarely as twice a year." In regards to premium users keep them standard. Non premium users can be in the infrequent since they have 6 hrs. Cost Effective!

officedepotadmin 👍 5 Answered CS3 One Zone-IA is a cost-effective storage option for images that are accessed infrequently but are still needed for AI model training twice a year. One Zone-IA stores data in a single Availability Zone, making it less expensive but still highly available within that zone. Premium users need frequent access to their AI-generated images so S3. Non-premium users access their AI-generated images less frequently (once every 6 hours) so S3 Standard-IA

Oghare 👍 3this is A S3 Glacier Deep Archive is the most cost-effective storage for long-term infrequently accessed data, ideal for the user-uploaded images used twice a year for AI training. S3 Standard for premium user-generated AI images ensures fast access, which is needed for frequent downloads. S3 Standard-IA for non-premium user-generated AI images is cost-effective for less frequent access, as it charges lower for storage but slightly more for retrieval, which fits the 6-hour download frequency. Not C because, although S3 One Zone-IA is a lower-cost option as well it provides less durability because it stores data in only one Availability Zone. While it is cost-effective, it increases the risk of data loss for critical AI training data. B and D is out S3 Glacier Flexible Retrieval for all generated AI images would likely introduce unacceptable retrieval delays for premium users, as they require immediate access to download images

Cpso 👍 3 Answered AI choose A. But it not best answer. for standard-ia you get data immediately but pay for request which not make sense for requirement. The best fit of non-premium user is Glacier Fleixble standard(1-5hour)

[Removed] 👍 2 Answered BB is correct Explanation: S3 Glacier Deep Archive is the most cost-effective storage option for data that is rarely accessed. Since the user-uploaded images are only used twice a year for AI model training, storing them in Glacier Deep Archive is ideal for minimizing costs. The longer retrieval time (up to 12 hours) is acceptable given the infrequent access. S3 Glacier Flexible Retrieval is suitable for storing the generated AI images because it balances cost and retrieval time. Regular users can download images every 6 hours, which Glacier Flexible Retrieval can accommodate with its flexible retrieval options (ranging from minutes to hours). This solution also works for premium users, who might need more frequent access. While S3 Standard or Standard-IA could be used, Glacier Flexible Retrieval offers significant cost savings while still meeting the access requirements.

LeonSauveterre 👍 2 Answered CA - Deep Archive is designed for long-term cold storage and can spend hours to retrieve each object. For AI model training, you'd hate it if you must spend hundreds/thousands of hours before you can actually start training it. B - Premium users would be so mad if they had to wait for hours to get their generated images. C - S3 One Zone-IA reduces costs, and it's great now that we don't need high durability across multiple availability zones. Premium users will experience low latency to get their generated images. D - Glacier tiers are not designed for frequent access. This is bad practice. One more thing about option C, since training happens extremely infrequently and the images can be re-uploaded if necessary, One Zone IA's lower redundancy is an acceptable trade-off for cost savings.

tch 👍 2 Answered AS3 Glacier Deep Archive is Amazon S3’s lowest-cost storage class and supports long-term retention and digital preservation for data that may be accessed once or twice in a year B& D are out.....
-
kbgsgsgs 👍 1 Answered CS3 Glacier Deep Archive does not meet the 6-hour download requirement because it takes time to access data. User can download even if you are not a premium user

pujithacg8 👍 1A is correct as Glacier deep archive provides the lowest-cost storage class.
