Exam CV0-004 topic 1 question 40 discussion

The correct answer is: C. Block ⸻ ✅ Explanation: Block storage offers the greatest performance advantage for traditional relational databases because: • It provides low-latency, high-throughput access to data. • It’s structured like a hard drive, allowing fine-grained control over how data is read/written. • Ideal for transaction-heavy applications like MySQL, PostgreSQL, Oracle, etc. ⸻ ❌ Why the other options are less suitable: • A. File storage – Good for shared files and NAS setups but slower and less efficient for database workloads. • B. Object storage – Great for unstructured data (like images or backups), but not optimized for frequent reads/writes or small transactions typical of relational databases. • D. Ephemeral storage – Tied to the lifecycle of a virtual machine; fast, but not persistent or reliable for database storage.
