Google Cloud Digital Leader — Question 144

An organization stores backup files in Cloud Storage. The files will be accessed annually to test the disaster recovery plans. Which storage class is the most cost-effective?

Answer options

• A. Coldline class
• B. Standard class
• C. Nearline class
• D. Archive class

Correct answer: D

Explanation

The Archive class is the most cost-effective for infrequent access data like annual backups, as it is designed for long-term storage with low retrieval costs. The Coldline class is suitable for data accessed less than once a year but is more expensive than Archive. The Standard class is intended for frequently accessed data, making it inappropriate for this scenario, while Nearline is aimed at data accessed less than once a month, which does not fit the annual access requirement.
