What is the primary advantage of using a distributed database?

• A. Lower data redundancy
• B. Data access and processing speed faster
• C. Simplified security
• D. Easier data backup

Answer: (B)

Distributing data across multiple machines enables parallel processing and data locality, so queries and transactions can be served more quickly. When data is spread over several nodes, the system can handle multiple requests at once and bring data from the nearest node, reducing latency and increasing overall throughput as usage grows. This parallelism and proximity is why faster data access and processing is the main advantage of a distributed database. The other options don’t capture this primary benefit: redundancy may be increased to support fault tolerance, but that’s a trade-off rather than the main gain; security becomes more complex across multiple nodes rather than simpler; and backups in a distributed setup can be more involved than on a single system.
