Router

Theshow running-configcommand is used on a Cisco router to display the current operational settings that are actively configured in the router’s RAM. This command outputs all the configurations that are currently being executed by the router, which includes interface configurations, routing protocols, access lists, and other settings. Unlikeshow startup-config, which shows the saved configuration that the router will use on the next reboot,show running-configreflects the live, current configuration in use.

References:= The information is supported by multiple sources that detail the use of Cisco commands, particularly theshow running-configcommand as the standard for viewing the active configuration on a Cisco device123.

show running-config: This command displays the current configuration running on the router. It includes all the operational settings and configurations applied to the router.

show protocols: This command shows the status of configured protocols on the router but not the entire configuration.

show startup-config: This command displays the configuration saved in NVRAM, which is used to initialize the router on startup, but not necessarily the current running configuration.

show version: This command provides information about the router's software version, hardware components, and uptime but does not display the running configuration.

To list the IPv4 addresses associated with the host name www.companypro.net, you should use the following command:

nslookup www.companypro.net

This command will query the DNS servers to find the IP address associated with the hostname provided.If you want to ensure that it returns the IPv4 address, you can specify the-type=Aoption, which stands for Address records that hold IPv4 addresses1. However, thenslookupcommand by default should return the IPv4 address if available.

To list the IPv4 addresses associated with the host namewww.companypro.net , you should use thenslookupcommand.

Command: nslookup

Target:www.companypro.net

So, the completed command is:

nslookupwww.companypro.net

nslookup: This command is used to query the Domain Name System (DNS) to obtain domain name or IP address mapping or for any other specific DNS record.

www.companypro.net : This is the domain name you want to query to obtain its associated IP addresses.

The correct matching of the security options to their characteristics is as follows:

WPA2-Enterprise: Uses a RADIUS server for authentication

WEP: Uses a minimum of 40 bits for encryption

WPA2-Personal: Uses AES and a pre-shared key for authentication

Here’s why each security option matches the characteristic:

WPA2-Enterpriseuses a RADIUS server for authentication, which provides centralized Authentication, Authorization, and Accounting (AAA) management for users who connect and use a network service.

WEP (Wired Equivalent Privacy)is an outdated security protocol that uses a minimum of 40 bits for encryption (and up to 104 bits), which is relatively weak by today’s standards.

WPA2-Personal(Wi-Fi Protected Access 2 - Personal) uses the Advanced Encryption Standard (AES) for encryption and a pre-shared key (PSK) for authentication, which is shared among users to access the network.

These security options are essential for protecting wireless networks from unauthorized access and ensuring data privacy.
