Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Standard: Frequently accessed data, short retention period
The correct matches are: Standard for frequently accessed data, Nearline for data accessed less than once a month, Coldline for data accessed less than once a quarter, and Archive for data accessed less than once a year. Common confusions involve misremembering the access frequency thresholds.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Standard: Frequently accessed data, short retention period
Why this is correct
Standard storage is the default and most expensive per-GB class, optimized for data accessed frequently and requiring low latency. It has no minimum retention period, so you can delete objects at any time, making it suitable for short retention periods like active databases or recent logs. The trade-off is that you pay a premium for immediate access and high throughput, whereas less frequently accessed data can be moved to cheaper classes.
Nearline: Data accessed less than once a month, 30-day minimum storage
Why this is correct
Nearline is a low-cost storage class designed for data accessed less than once a month, such as backups, long-tail media, or compliance records that must be retrievable within seconds. It has a 30-day minimum storage duration; deleting before that incurs an early-deletion fee. This class balances lower storage costs than Standard with moderate retrieval charges, making it a sensible choice when data is rarely needed but must be available on demand.
Coldline: Data accessed less than once a quarter, 90-day minimum storage
Why this is correct
Coldline is optimized for data that will be accessed at most once a quarter, like older disaster recovery snapshots or archival backups that may be needed for periodic audits. It enforces a 90-day minimum storage duration, and early deletion incurs a penalty. While storage costs are significantly lower than Nearline, retrieval costs are higher, so it is only economical when access patterns are truly seasonal or rare.
Archive: Data accessed less than once a year, 365-day minimum storage
Why this is correct
Archive is the lowest-cost storage class, intended for data accessed less than once a year, such as legal records, historical research data, or regulatory archives that must be retained for years. It has a 365-day minimum storage duration, and early deletion triggers a pro-rated charge. Retrieval may take hours or even minutes, so Archive is unsuitable for time-sensitive access, but for durable, cost-effective long-term preservation, it is the optimal choice.
Standard: Data accessed less than once a year
Why it's wrong here
Pairing Standard with 'data accessed less than once a year' is incorrect because Standard is built for frequent, low-latency access, not for archival scenarios. The described access frequency and long retention period directly match Archive, which offers the lowest storage cost for yearly or less-frequent access. Selecting Standard for such data would incur unnecessarily high storage expenses without benefiting from its no-minimum-duration flexibility.
Nearline: Data accessed less than once a quarter
Why it's wrong here
Assigning Nearline to 'data accessed less than once a quarter' is incorrect because that cadence specifically defines Coldline, which features a 90-day minimum storage duration and is priced for quarterly access. Nearline, in contrast, targets data accessed roughly monthly, with a shorter 30-day minimum, and thus occupies a different point in the cost–access trade-off. Mistaking the two would lead to either overpaying (if using Nearline for quarterly data) or under-provisioning for monthly access (if using Coldline for monthly data).
