Your company generates 5 TB of log data daily. The data must be stored for 5 years for compliance reasons. The data is accessed frequently during the first 30 days for troubleshooting, rarely accessed between 30 and 365 days, and almost never accessed after 1 year. Which Cloud Storage lifecycle policy is the most cost-effective?

Which Cloud Storage lifecycle policy is the most cost-effective?
Answer options:
A.
Standard for 30 days, transition to Coldline for 335 days, then transition to Archive for the remaining 4 years.
B.
Standard for 30 days, transition to Nearline for 335 days, then transition to Archive for the remaining 4 years.
C.
Nearline for 365 days, then transition to Archive.
D.
Standard for 5 years.
How to approach this question
Map the access frequency to the correct storage class: Frequent = Standard, < once a month = Nearline, < once a quarter = Coldline, < once a year = Archive.
Full Answer
B.Standard for 30 days, transition to Nearline for 335 days, then transition to Archive for the remaining 4 years.✓ Correct
Standard for 30 days, transition to Nearline for 335 days, then transition to Archive for the remaining 4 years.
Cloud Storage classes are optimized for access frequency. Standard is for hot data (first 30 days). Nearline is for data accessed less than once a month (days 31-365). Archive is for data accessed less than once a year (years 2-5). Using Object Lifecycle Management to automate these transitions provides the lowest total cost of ownership.
Common mistakes
Using Coldline instead of Nearline for data that might be accessed occasionally during the first year, leading to high retrieval fees.
