📝 Sample Questions

Q1. What is the primary characteristic that distinguishes a type 0 hypervisor from other hypervisor types?

🔹 A. Implemented primarily in software and loaded after the operating system boots

🔹 B. Runs as a separate application within a host OS

🔹 C. Implemented in hardware/firmware and loaded at boot time

🔹 D. Provides only network virtualization

💡 Difficulty: easy | ✅ Correct: C

Q2. A server has four virtual machines but only two physical Ethernet ports. Which strategy best ensures each VM can communicate externally while minimizing performance impact?

🔹 A. Assign both ports to a single VM and leave the others without network access

🔹 B. Use a software bridge to share the two ports among all VMs

🔹 C. Install additional physical NICs for each VM

🔹 D. Disable networking for the two VMs that do not need it

💡 Difficulty: medium | ✅ Correct: B

Q3. How does implementing a hypervisor as a type 0 hardware feature affect I/O device isolation compared to a type 2 software hypervisor?

🔹 A. Type 0 provides stronger isolation because each guest can be assigned dedicated hardware I/O paths

🔹 B. Type 0 requires more CPU cycles for I/O emulation

🔹 C. Type 2 can allocate I/O devices dynamically without any performance penalty

🔹 D. Type 0 eliminates the need for any I/O device sharing mechanisms

💡 Difficulty: hard | ✅ Correct: A
