Topic 1 Question 265
You are designing a fault-tolerant architecture to store data in a regional BigQuery dataset. You need to ensure that your application is able to recover from a corruption event in your tables that occurred within the past seven days. You want to adopt managed services with the lowest RPO and most cost-effective solution. What should you do?
Access historical data by using time travel in BigQuery.
Export the data from BigQuery into a new table that excludes the corrupted data
Create a BigQuery table snapshot on a daily basis.
Migrate your data to multi-region BigQuery buckets.

- 正解だと思う選択肢: A
- Lowest RPO: Time travel offers point-in-time recovery for the past seven days by default, providing the shortest possible recovery point objective (RPO) among the given options. You can recover data to any state within that window.
- No Additional Costs: Time travel is a built-in feature of BigQuery, incurring no extra storage or operational costs.
- Managed Service: BigQuery handles time travel automatically, eliminating manual backup and restore processes.
