Answer to Q5 Practice Exam – Timed Mode Set 3 – AWS CCP

[mforest]

Question 5 in the Practice Exam Set 3 asks, You have a large number of log files that will be archived in AWS for a long time and should have a retrieval time of 12 hours or less. Which service is the most cost-effective storage class for this purpose?

The answer says: Amazon S3 Glacier Deep Archive

However, the documentation here (https://aws.amazon.com/s3/storage-classes/) mentions that “To save even more on long-lived archive storage such as compliance archives and digital media preservation, choose S3 Glacier Deep Archive, the lowest cost storage in the cloud with data retrieval from 12—48 hours.“

Wouldn’t Amazon S3 Glacier Instant Retrieval be the correct answer in that case, since S3 Glacier Deep Archive does not have retrieval time of 12 hours or less?

Hello mforest,

Good day!

Thank you for posting here.

Amazon S3 Glacier Deep Archive is this scenario’s correct and most cost-effective solution. The question specifically mentions the long-term archiving of log files, which aligns perfectly with S3 Glacier Deep Archive’s design for long-term data retention at the lowest cost in the AWS ecosystem. While its retrieval time is listed as 12-48 hours, the lower end of this range (12 hours) meets the stated requirement of “12 hours or less.” For archival data that doesn’t require frequent access, this retrieval time is acceptable, especially when balanced against the significant cost savings for long-term storage. S3 Glacier Instant Retrieval, despite its faster access times, would be unnecessarily expensive for this use case where immediate retrieval isn’t required. Therefore, considering the long-term storage needs and cost-effectiveness emphasized in the question, the S3 Glacier Deep Archive is the most appropriate choice.

I hope this helps.

Thank you,
