  1. Which layer of the OSI model is responsible for logical addressing and routing packets between networks?

    Answer: Network

    The Network layer (Layer 3) handles logical addressing (IP) and determines the best path for routing packets across networks.

  2. A technician needs to find the MAC address of a Windows PC. Which command should they use?

    Answer: ipconfig /all

    The 'ipconfig /all' command displays detailed network adapter information including the physical (MAC) address.

  3. What is the default subnet mask for a Class B IP address?

    Answer: 255.255.0.0

    Class B addresses use a default subnet mask of 255.255.0.0, covering the range 128.0.0.0 to 191.255.255.255.

  4. Which protocol automatically assigns IP addresses to devices on a network?

    Answer: DHCP

    DHCP (Dynamic Host Configuration Protocol) dynamically assigns IP addresses, subnet masks, gateways, and DNS servers to network clients.

  5. What does the acronym 'LAN' stand for?

    Answer: Local Area Network

    LAN stands for Local Area Network, referring to a network that covers a small geographic area such as a building or campus.

  6. At which OSI layer do switches primarily operate?

    Answer: Layer 2 - Data Link

    Standard switches operate at Layer 2 (Data Link) and forward frames based on MAC addresses in their CAM table.

  7. Which IPv4 address range is reserved for loopback testing?

    Answer: 127.0.0.0/8

    The 127.0.0.0/8 range is reserved for loopback; pinging 127.0.0.1 tests the local TCP/IP stack without sending traffic to the network.
