Q1. What is binary translation in the context of virtualization?

🔹 A. A technique that dynamically rewrites guest code to run on a host CPU.

🔹 B. A static mapping of virtual addresses to physical memory.

🔹 C. A method of encrypting hypervisor binaries.

🔹 D. A protocol for remote desktop connections.

💡 Difficulty: easy | ✅ Correct: A

Q2. Why does binary translation become more challenging on dual‑mode CPUs that only have user and kernel modes?

🔹 A. Because the host cannot directly execute guest kernel‑mode instructions without trapping them.

🔹 B. Because the guest's privileged instructions are identical to the host's user‑mode instructions.

🔹 C. Because dual‑mode CPUs lack any virtualization extensions to assist translation.

🔹 D. Because the guest OS does not need any privileged instructions on such CPUs.

💡 Difficulty: medium | ✅ Correct: C

Q3. What is the main security implication of using binary translation to execute privileged guest code on a host without hardware support?

🔹 A. It isolates the guest completely, preventing any host compromise.

🔹 B. It introduces a larger attack surface because the translator must emulate privileged behavior.

🔹 C. It guarantees that all guest vulnerabilities are sanitized before execution.

🔹 D. It forces the guest to run in user mode, eliminating privilege escalation risks.

💡 Difficulty: hard | ✅ Correct: B
