A local car dealership recently purchased an automobile financing company. The owner of the dealership issues a contract to NetworkingCompany to integrate the finance company network into the car dealership network. A router in the existing finance company network requires a password for both Telnet and console access, but no one remembers the passwords. What can the NetworkingCompany network technician do to obtain or change the passwords and gain access to the router?
- Use a TFTP server to download a new configuration file to the router that contains the passwords used on the car dealership network and then reload the router.
- Connect a rollover cable to the serial0/0 port of the router in order to bypass the password security, and use the show running-config command to obtain the passwords.
- Connect a console cable to the router, power cycle the router, issue a Ctrl-Break to enter ROM monitor mode, and change the configuration register to bypass the startup configuration.
- Connect the router to another Cisco router at the car dealership, use the show cdp neighbors command to obtain an IP address of the router, and use SSH to gain secure access in order to view the passwords.
