The IEEE 802.11 standard contains the specifications for Wi-Fi networks. It is a set of media access control (MAC) and physical layer (PHY) specifications for implementing wireless local area network (WLAN) computer communication in various frequencies, including but not limited to 2.4 GHz, 5 GHz, and 6 GHz1. This standard is maintained by the Institute of Electrical and Electronics Engineers (IEEE) and is commonly referred to as Wi-Fi. The standard has evolved over time to include several amendments that improve speed, range, and reliability of wireless networks.

The AAA service security model consists of three components: Authentication, Authorization, and Accounting.

•Authentication: This is the process of verifying the identity of a user or device. It ensures that only legitimate users can access the network or service.

•Authorization: This determines what an authenticated user is allowed to do or access within the network.

•Auditing/Accounting: This component tracks the actions of the user, including what resources they access and what changes they make.

Thus, the correct answer is C. Authentication.

To determine if you can reach the router, you should use thepingcommand followed by the IP address of the router. Thepingcommand is a network utility used to test the reachability of a host on an Internet Protocol (IP) network and to measure the round-trip time for messages sent from the originating host to a destination computer.

The Default Gateway in theipconfigresults is typically the router’s IP address in a home or small office network. In this case, the Default Gateway is192.168.0.1, which is the address you would ping to check connectivity to the router.

=========================

To determine if you can reach the router, you should use thepingcommand with the IP address of the router.

• Command:ping
• Target:192.168.0.1

So, the completed command is:

• ping 192.168.0.1

Step by Step Comprehensive and Detailed Explanation:

• ping: The ping command sends ICMP Echo Request messages to the target IP address and waits for an Echo Reply. It is commonly used to test the reachability of a network device.
• 192.168.0.1: This is the IP address of the default gateway (the router) as shown in theipconfigoutput. Pinging this address will help determine if the computer can communicate with the router.
