  1. What is the primary purpose of a firewall on a network?

    Answer: To monitor and filter incoming and outgoing network traffic based on security rules

    A firewall monitors and controls network traffic based on predefined security rules, blocking unauthorized access while allowing legitimate traffic.

  2. Which type of network cabling is most commonly used in modern wired Ethernet installations?

    Answer: Twisted pair (UTP) cable

    Unshielded Twisted Pair (UTP) cable, such as Cat5e or Cat6, is the most widely used medium for wired Ethernet networks in homes and offices.

  3. What does VPN stand for, and what is its main use?

    Answer: Virtual Private Network — creates an encrypted tunnel for secure remote access

    A VPN (Virtual Private Network) creates an encrypted tunnel over a public network, allowing secure remote access as if the user were directly connected to the private network.

  4. Which wireless security protocol is recommended as the most secure option for protecting a home Wi-Fi network?

    Answer: WPA2 (Wi-Fi Protected Access 2)

    WPA2 uses AES encryption and is significantly more secure than WEP and WPA, making it the recommended standard for home and small business wireless networks.

  5. In networking, what does the term 'bandwidth' refer to?

    Answer: The maximum rate at which data can be transferred over a network connection

    Bandwidth refers to the maximum data transfer capacity of a network connection, typically measured in Mbps (megabits per second) or Gbps.

  6. Which networking device operates at Layer 2 of the OSI model and uses MAC addresses to forward traffic only to the correct destination port?

    Answer: Switch

    A switch operates at the Data Link layer (Layer 2), maintaining a MAC address table to forward frames only to the port where the destination device is connected.

  7. What is the purpose of NAT (Network Address Translation)?

    Answer: To translate private internal IP addresses to a single public IP address for internet access

    NAT allows multiple devices on a private network to share a single public IP address when accessing the internet, conserving IPv4 addresses.
