Google Cloud Digital Leader Practice Exam

A data analyst for an online retailer must produce a sales report at the end of each quarter. Which Cloud Storage class should the retailer use for data accessed every 90 days?

1. Coldline

2. Standard

3. Nearline

4. Archive

The correct answer is: Coldline

The ideal choice for a sales report that is accessed every 90 days is the Coldline storage class. This class is specifically designed for data that is infrequently accessed, allowing users to store their data at a lower cost compared to more frequently accessed storage options. Coldline is optimized for long-term storage of data that is accessed less than once a year, making it suitable for quarterly reports. This option offers a balance between cost-efficiency for infrequent access and the capability to retrieve data when needed, aligning perfectly with the retail analyst's requirements for quarterly sales reporting. In contrast, the Standard storage class is intended for data that is accessed often, while Nearline is designed for data that is expected to be accessed at least once a month, which does not align with the quarterly access pattern. The Archive class is aimed at data that is rarely accessed or needs to be stored for a long duration but might come with higher retrieval costs compared to Coldline in situations like this. Thus, Coldline provides the most suitable and cost-effective solution for the user's data access needs, given the specified frequency.
