A: ROM Monitor — low-level boot mode used for password recovery, firmware recovery, and IOS reinstallation.
Q: What is the password recovery process for a Cisco router?
A: 1. Reboot and break to ROMMON. 2. Change config register to 0x2142. 3. Reboot (skips startup-config). 4. Reset password. 5. Restore config register to 0x2102.
Q: What does "show ip interface brief" display?
A: Quick view of all interfaces: IP address, status (up/down), and protocol (up/down).
Q: What is an SFP module?
A: Small Form-factor Pluggable — hot-swappable transceiver module for Ethernet/fiber connections.
Q: What does interface status "up/down" mean?
A: Layer 1 (physical) is up, but Layer 2 (data link) protocol is down. Usually a configuration or encapsulation mismatch.
Q: How do you save the running configuration?
A: copy running-config startup-config (or write memory / wr).

Cisco Flashcard Study Strategy
Cisco exams heavily test protocol operations and configuration details. Use these flashcards to drill port numbers, protocol behaviours, and administrative distances. Pair flashcard sessions with Packet Tracer labs — when you encounter a card about OSPF neighbour states, open a lab and verify each state transition on a live topology. This combination of memorisation and practice builds the deep understanding Cisco exams demand.
