Correct answer: show inventory

The `show inventory` command provides a detailed list of all physical hardware components detected by the router, including chassis, modules, cards (like HWICs), and SFPs. It will display the Product ID (PID) and Serial Number (SN) of the installed hardware. This is the correct command to confirm if the router's mainboard is physically recognizing the newly installed module, even before the IOS has configured interfaces for it.

Correct answer: boot

After initializing the flash and renaming the configuration file (e.g., `rename flash:config.text flash:config.bak`), the `boot` command is used from the `switch:` prompt (ROMMON) to continue the boot process. Since the original `config.text` is not found, the switch will load without a configuration, allowing the technician to enter privileged EXEC mode and reset the password.

Correct answers: 9600 Bits per second; 8 Data bits; No Parity

The default speed for a Cisco console port is 9600 bps.

The standard setting for data bits is 8.

The parity bit is not used and should be set to 'None'.

Correct answer: The chassis serial number of the old device

The chassis serial number is the unique identifier for the physical hardware. It is absolutely essential for the Return Material Authorization (RMA) process. Cisco uses this number to track the faulty unit, validate the service contract, and process the return. Failure to record the correct serial number can lead to significant delays and complications in closing the service ticket and processing the RMA.

Correct answer: ip domain-name finsecure.local

To generate RSA keys for SSH, the `crypto key generate rsa` command requires two prerequisites: a hostname and an IP domain name. The case study mentions setting the hostname, but it does not mention setting an IP domain name. Without the `ip domain-name` command being configured in global configuration mode, the RSA key generation will fail, and consequently, SSH access cannot be enabled. This is a critical and often overlooked step in the initial setup for SSH.

Correct answer: False

This statement is false. Both a PC's NIC and a router's Ethernet port are DTE (Data Terminal Equipment) devices, which use the same pins for transmitting and receiving (MDI). To connect two like devices, a crossover cable is required to swap the transmit and receive pairs. A straight-through cable would be used to connect a PC to a switch (DCE/MDI-X device). While modern devices often support Auto-MDI/MDI-X, the standard cabling rule requires a crossover.

Correct answer: The supervisor slots have a red or colored border around them and are labeled.

On many modular Cisco chassis, including the Catalyst 4500 series, the slots designated for supervisor engines are physically marked to prevent incorrect installation. This often includes a colored outline (typically red or yellow) around the slot opening on the chassis frame and specific labeling indicating it is a supervisor slot. These visual cues are designed for technicians to quickly and accurately identify the correct placement for these critical components.

Correct answer: The `shutdown` command is configured on the interface.

The status 'administratively down' specifically means that the `shutdown` command has been issued in the interface's configuration mode. This is a deliberate action by an administrator to disable the port. To bring the interface up, the `no shutdown` command must be used. Other issues like a missing cable or speed mismatch would result in a line protocol status of 'down', but the administrative status would be 'up'.

Correct answers: Pins 1 and 4 are looped; Pins 2 and 5 are looped

Pin 1 (Receive Ring) is looped to Pin 4 (Transmit Ring).

Pin 2 (Receive Tip) is looped to Pin 5 (Transmit Tip).

Correct answer: verify /md5 flash:

The `verify /md5` command is the specific IOS tool used to compute an MD5 checksum for a file stored in a file system like flash memory. The technician would run this command, specifying the full path to the IOS image file, and then compare the output hash with the one published on the Cisco Software Download site to ensure the file has not been corrupted or tampered with.
