Basic Trivia Quiz On Routing!

1. A network administrator needs to keep the user ID, password, and session contents private when establishing remote CLI connectivity with a router to manage it. Which access method should be chosen?

Telnet

Console

AUX

SSH

SSH (Secure Shell) should be chosen as the access method because it provides secure remote CLI connectivity. Unlike Telnet, which transmits data in clear text, SSH encrypts the data, ensuring the privacy and integrity of user ID, password, and session contents. Console and AUX are not suitable for remote connectivity as they require physical access to the router.

2. What command is used to change the default router name to Fontana?

Router# name Fontana

Router# hostname Fontana

Router(config)# name Fontana

Router(config)# hostname Fontana

The correct answer is "Router(config)# hostname Fontana". This command is used to change the default router name to "Fontana". The "hostname" command is used in global configuration mode (indicated by "config#") to specify the name that will appear in the prompt of the router. By entering this command followed by the desired name, in this case "Fontana", the router's hostname will be changed accordingly.

By entering this command followed by the desired name, in this case "Fontana", the router's hostname will be changed accordingly.

3. When network services fail, which port is most often used to access a router for management purposes?

AUC

Ethernet

Console

Telnet

SSH

Console is the correct answer because when network services fail, the console port is commonly used to access a router for management purposes. The console port provides a direct physical connection to the router, allowing administrators to access the device even if network connectivity is not available. This port is typically used for initial configuration, troubleshooting, and recovery tasks.

4. Which combination of keys would be used at the CLI prompt to interrupt a ping or traceroute process?

Ctrl-C

Ctrl-P

Ctrl-R

Ctrl-Shift-6

Ctrl-Z

Ctrl-Shift-6 is the correct combination of keys to interrupt a ping or traceroute process at the CLI prompt. This key combination is commonly used in networking devices to stop a running process. It sends a break signal to the device, causing it to terminate the current operation and return to the command prompt. Ctrl-C is a commonly used key combination for interrupting processes, but in this case, Ctrl-Shift-6 is the correct answer. Ctrl-P, Ctrl-R, and Ctrl-Z do not interrupt ping or traceroute processes.

Ctrl-C is a commonly used key combination for interrupting processes, but in this case, Ctrl-Shift-6 is the correct answer. Ctrl-P, Ctrl-R, and Ctrl-Z do not interrupt ping or traceroute processes.

5. In a Cisco router, when do changes made to the running-configuration take effect?

After a system restart

As the commands are entered

When logging off the system

When the configuration is saved to the startup-configuration

Changes made to the running-configuration in a Cisco router take effect as the commands are entered. This means that any changes made to the configuration will immediately be applied and take effect without the need for a system restart, logging off the system, or saving the configuration to the startup-configuration.

This means that any changes made to the configuration will immediately be applied and take effect without the need for a system restart, logging off the system, or saving the configuration to the startup-configuration.

6. Users in the network are experiencing slow response time when doing file transfers to a remote server. What command could be issued to determine if the router has experienced any input or output errors?

Show running-config

Show startup-config

Show interfaces

Show ip route

Show version

The command "show interfaces" can be issued to determine if the router has experienced any input or output errors. This command will display the status and statistics of all interfaces on the router, including any errors that may have occurred during file transfers. By examining the output of this command, network administrators can identify if there are any issues with the router's interfaces that may be causing the slow response time.

7. Which three terms correctly define the forms of help available within the Cisco IOS? (Choose three.)

Hot keys

Context-check

Context-sensitive

Structured check

Command override

The three terms that correctly define the forms of help available within the Cisco IOS are hot keys, context-sensitive, and command override. Hot keys refer to keyboard shortcuts that provide quick access to specific functions or commands. Context-sensitive help provides relevant information based on the current context or command being entered. Command override allows users to override or modify certain commands or settings within the IOS.
