When deploying a database in a cloud environment, what is a key consideration for ensuring data durability?
Correct Answer: A. Using multi-region storage replication
When deploying a database in a cloud environment, using multi-region storage replication is a key consideration for ensuring data durability. This strategy involves copying data across multiple geographic regions to protect it from localized failures, outages, or disasters. Even if one data center becomes unavailable, the replicated data in another region ensures continuity, resilience, and durability. It’s a best practice in cloud architecture to maintain data integrity and high availability in distributed systems.
Why Other Options are Incorrect:
B. Prioritizing in-memory data storage
In-memory storage provides faster performance but is volatile, meaning data is lost if the system crashes or reboots. It is not suitable for durability, as it lacks persistent, long-term storage across failures or shutdowns.
C. Optimizing SQL queries
Optimizing SQL queries improves performance and efficiency, not durability. While helpful for speeding up transactions and reducing load, it does not protect data from loss in case of system or regional failures.
D. Implementing data deduplication
Data deduplication conserves storage space by eliminating duplicate data, but it does not enhance durability. It can support storage efficiency but offers no protection against data loss due to system or regional failures.
