Master Cisco Supporting Cisco Routing & Switching Network Devices 100-490: Your Gateway to Network Mastery

Correct : C

The show inventory command in Cisco IOS is designed specifically to display detailed hardware inventory information about a Cisco device. This includes:

Component Name: The name or type of each module or card installed.

PID (Product ID): The unique product identifier for the module.

VID (Version ID): The version identifier for the module.

Serial Number: The unique serial number assigned to the module.

Why other options are incorrect:

show chassis: Some Cisco devices support a show chassis command, but the information provided usually focuses on the physical chassis rather than detailed component inventory.

show items: This is not a standard Cisco IOS command.

show router: This command doesn't provide the level of granular hardware information that show inventory does.

Correct : B

Microsoft Notepad is the preferred text editor for working with Cisco configuration files and other simple text documents for several reasons:

Plain Text Focus: Notepad is designed specifically for plain text editing. It does not add any formatting, hidden characters, or metadata that could interfere with the configuration file's structure.

Cisco Syntax Compatibility: Cisco configurations rely on specific syntax and spacing. Notepad preserves these elements accurately.

Universality: Notepad is a basic text editor included in all versions of Windows, ensuring accessibility and eliminating the need for additional software.

Why other options are not ideal:

Microsoft Word: Word is a word processor and includes formatting, fonts, and other features that are not compatible with Cisco configuration files. This formatting can corrupt the configuration.

Microsoft Access: Access is a database management system, not suited for text file editing.

Microsoft Excel: Excel is a spreadsheet application and adds its own structure and formatting that conflicts with configuration file formats.

Correct : C

The ipconfig command in Windows is used to display and manage network configuration information for the local computer. Here's what it shows:

IP Address: The IPv4 address assigned to each network adapter.

Subnet Mask: The subnet mask used to determine the network segment.

Default Gateway: The IP address of the router used to send traffic to other networks.

Other Information: DNS servers, DHCP server details, and more.

Incorrect options:

ipconfiguration: This is not a recognized command in the Windows command prompt.

ip configuration: This is also not a recognized command.

ip config: While it might seem like it should work, Windows uses ipconfig without spaces.

How to use ipconfig:

Open the Windows command prompt (Search for 'cmd')

Type ipconfig and press Enter.

Correct : A

The cmd program, also known as the Command Prompt, is the primary command-line interface in Windows. It allows you to execute various commands, including the ping command, to perform network testing and troubleshooting.

Here's how to use ping in the Command Prompt:

Open the Command Prompt: Search for 'cmd' in the Windows Start Menu or use the Run dialog (Windows key + R) and type 'cmd'.

Type the ping command: Enter ping followed by a space and then either the IP address or hostname you want to test. For instance: ping 8.8.8.8 or ping www.google.com.

Press Enter: The Command Prompt will send ping requests and display the results.

Why other options are incorrect:

Find: The Find utility in Windows is used to search for files and folders based on their content or attributes.

Start: The Start Menu in Windows provides access to programs, settings, and power options.

ipconfig: The ipconfig command is used to display network configuration information but doesn't directly execute the ping command.

A Cisco router can be configured to act as a TFTP (Trivial File Transfer Protocol) server. TFTP is a simple protocol used to transfer files without the need for authentication. On a Cisco router, the tftp-server command is used to designate the router as a TFTP server, allowing it to manage file transfers to and from connected devices. This is particularly useful for tasks such as updating the router's firmware or backing up configuration files. Neither CSU/DSU, modem, nor Cisco Content Engine are typically used as TFTP servers. Reference := The ability to configure a Cisco router as a TFTP server is documented in Cisco's support forums and knowledge base articles
