What should a rapidly growing e-commerce company implement to ensure critical data is protected during potential system failures?

• A. Load balancing
• B. Archiving
• C. Replication
• D. Database indexing

Answer: (C)

Replication is a critical strategy for ensuring data protection in rapidly growing systems, particularly for an e-commerce company that may face potential system failures. By creating copies of data across different locations or servers, replication allows for real-time backup and restoration. In the event of a system failure, the replicated data can quickly be accessed, which minimizes downtime and ensures that customer transactions and sensitive data remain intact.

This approach is especially vital for e-commerce businesses that rely on continuous operations and availability. Should one system go down, the replicated data in another location can be immediately utilized to maintain service continuity and protect against data loss.

In contrast, load balancing, while beneficial for distributing traffic and workload among servers, does not directly address data protection; it mainly enhances performance and reliability during high traffic periods. Archiving, although important for long-term data preservation, generally involves storing older, less frequently accessed data and does not provide real-time data redundancy. Database indexing improves query performance but does not provide any form of backup or protection against system failures.
