📝 Sample Questions

Q1. A computer on a local Ethernet network wants to transfer a file to another computer whose IP address is known. Its ARP cache already contains the correct Ethernet (MAC) address. Which of the following actions will the sending host take next?

🔹 A. Broadcast an ARP request to find the MAC address
🔹 B. Send the Ethernet frame directly to the cached MAC address
🔹 C. Forward the packet to the default router
🔹 D. Drop the packet due to missing ARP entry

💡 Difficulty: easy | ✅ Correct: B

Q2. Host A (192.168.1.10) wants to access a remote file on Host B (10.0.0.5). Host A’s ARP cache lacks B’s MAC, but it knows the default gateway 192.168.1.1. What is the correct sequence of actions?

🔹 A. Send an ARP request for B’s MAC, then send directly
🔹 B. Send the packet to the default gateway’s MAC, which routes it onward
🔹 C. Drop the packet because the ARP entry is missing
🔹 D. Broadcast the packet on the LAN

💡 Difficulty: medium | ✅ Correct: B

Q3. Host X has an ARP cache entry mapping IP 203.0.113.20 to MAC AA:BB:CC:DD:EE:FF. The actual device with that IP has been replaced, but the stale entry remains. Host X attempts to retrieve a file from the new device. What is the most likely outcome?

🔹 A. The packet will reach the new device because routers update the MAC
🔹 B. The packet will be delivered to the old device, causing a failure
🔹 C. Host X will automatically resend an ARP request after a timeout, correcting the entry
🔹 D. The Ethernet frame will be broadcast to all hosts, ensuring delivery

💡 Difficulty: hard | ✅ Correct: B
