SAA-C03 Exam - Question 66

Question

A company has an application that generates a large number of files, each approximately 5 MB in size. The files are stored in Amazon S3. Company policy requires the files to be stored for 4 years before they can be deleted. Immediate accessibility is always required as the files contain critical business data that is not easy to reproduce. The files are frequently accessed in the first 30 days of the object creation but are rarely accessed after the first 30 days.

Which storage solution is MOST cost-effective?

Examice · Accepted Answer

Given that the files must be stored for 4 years and require immediate accessibility, S3 Standard-Infrequent Access (S3 Standard-IA) is suitable after the first 30 days because it offers lower cost storage for infrequently accessed data but still provides immediate access. S3 Glacier, while cheaper, introduces retrieval delays and costs, which is not compliant with the requirement for immediate accessibility. S3 One Zone-IA is not ideal for critical business data due to its lower durability. Therefore, the most cost-effective and compliant option is to move files from S3 Standard to S3 Standard-IA after 30 days and delete them after 4 years.

i think C should be the answer here, 
> Immediate accessibility is always required as the files contain critical business data that is not easy to reproduce

If they do not explicitly mention that they are using Glacier Instant Retrieval, we should assume that Glacier -> takes more time to retrieve and may not meet the requirements

ninjawrz · Answer

Most COST EFFECTIVE
A:  S3 Glacier Instant Retrieval is a new storage class that delivers the fastest access to archive storage, with the same low latency and high-throughput performance as the S3 Standard and S3 Standard-IA storage classes. You can save up to 68 percent on storage costs as compared with using the S3 Standard-IA storage class when you use the S3 Glacier Instant Retrieval storage class and pay a low price to retrieve data.

awsgeek75 · Answer

A: S3 Glacier does not provide immediate accessibility
B: "contain critical business data" so one zone IA is not safe in case of zone failure
D: Does not delete the file, just moves them to Glacier
C: S3 for first 30 days, S3 Standard IA for 4 years then deleted. Meets all requirements

The question ask the MOST cost-effective solution
"S3 One Zone-IA stores data in a single AZ and costs 20% less than S3 Standard-IA"

Solomon2001 · Answer

S3 One Zone-Infrequent Access (S3 One Zone-IA) is cheaper than S3 Standard and S3 Standard-Infrequent Access (S3 Standard-IA) but still offers immediate accessibility.
Since the files are rarely accessed after the first 30 days, transitioning them to S3 One Zone-IA after 30 days will reduce costs.
The 4-year retention period aligns with the company policy, and after this period, the files can be deleted.
Option C suggests moving the files from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-IA) after 30 days, which is a more expensive storage class compared to S3 One Zone-Infrequent Access (S3 One Zone-IA).

Since the files are rarely accessed after the first 30 days, moving them to S3 Standard-IA would result in higher storage costs compared to moving them to S3 One Zone-IA.

Therefore, option B is more cost-effective than option C.

Keep in mind that "Glacier Flexible Retrieval" was previously named just "Glacier" (before they added Instant Retrieval).  Regardless, they should have made it clear which Glacier class they are referring to since which one you select/assume can impact the correctness.

S3 glacier cannot provide immediate accessibility

Ikki77 · Answer

Option C: Create an S3 bucket lifecycle policy to move files from S3 Standard to S3 Standard-Infrequent Access (S3 Standard-IA) 30 days from object creation. Delete the files 4 years after object creation.

Options A, B, and D have drawbacks:

Option A: Transitioning to S3 Glacier might introduce retrieval times and costs, which may not be suitable for files that require immediate accessibility. Deleting directly after 4 years is a more straightforward approach.

Option B: S3 One Zone-Infrequent Access (S3 One Zone-IA) is less durable than Standard or Standard-Infrequent Access, as it stores data in a single availability zone. This may not be ideal for critical business data.

Option D: Transitioning to S3 Glacier after 4 years introduces retrieval times and costs, which might not align with the immediate accessibility requirement. It adds complexity without a clear benefit in this scenario.

bhushansathe · Answer

C is the correct answer

lofzee · Answer

I am going to go with B. Reasoning = 
A = even if Glacier Instant Retrieval was used here, you can only use that quick retrieval once a quarter which isn't what the prompt is asking for.
B - One Zone is the cheapest option, and the prompt does not ask for high availability.
C / D - see reasoning for B

bujuman · Answer

Recall: S3 Standard, S3 Standard-IA and S3 One Zone-IA are higher cost than Infrequent Access which include S3 Glacer-IR, S3 Glacier-FR, S3 Glacier-DA.

doransignal · Answer

answer is c because glacier is not immediate thats why a is not the answer

48cd959 · Answer

Ans -C
It should be C, As Glacier always takes some time in retrieval until they say that they are using Glacier instant access retrieval service.

LIORAGE · Answer

C: is good option because immediate accessibility is required

jatric · Answer

immidiately accessible for 4 years bur rarely use - S3 standard IA.
Correct answer is C
