350-401 Question #9: Real Exam Question with Answer & Explanation

Question

Which statement describes the IP and MAC allocation requirements for virtual machines on types 1 hypervisors?

Options

• AEach virtual machine requires a unique IP and MAC addresses to be able to reach to other
• BEach virtual machine requires a unique IP address but shares the MAC address with the physical
• CEach virtual machines requires a unique IP address but shares the MAC address with the
• DEach virtual machine requires a unique MAC address but shares the IP address with the physical

Explanation

Virtual Machine IP and MAC Address Allocation

Option A is correct because each virtual machine (VM) on a Type 1 hypervisor operates as an independent network entity, requiring its own unique IP address for Layer 3 routing and its own unique MAC address for Layer 2 switching - without these, network switches and routers would be unable to distinguish between VMs, causing communication failures.

Options B and C are incorrect because MAC addresses cannot be shared; sharing a MAC address would cause network collisions and prevent switches from properly directing frames to the correct destination. Option D is incorrect because sharing an IP address between VMs would create IP conflicts, making it impossible for traffic to be routed to the correct machine - each VM must have its own IP to function independently on the network.

🧠 Memory Tip: Think of VMs as "virtual computers" - just like physical computers on a network, each one needs both a unique IP and MAC address to have its own distinct identity. If two devices share either address, the network gets confused about "who is who."
