Selected Answer: B

The correct answer is: B. Microservices ⸻ ✅ Explanation: The engineer’s requirements point toward a modern, flexible, and secure architecture. Here’s how microservices best meet these needs: 🔐 Security Best Practice – Minimal Services: • Microservices architecture promotes isolated, single-purpose services, meaning each component runs only what it needs—reducing attack surfaces. 🌐 Vendor Agnostic: • Microservices can run on any platform (e.g., Kubernetes, Docker, VMs), making them portable across cloud providers. 💻 Virtualization over Physical Hardware: • Microservices are typically deployed in containers or VMs, which supports the requirement to use virtualization instead of relying on physical servers.
