Free FBLA Networking Infrastructures practice questions and answers

Try each question before opening the answer. Every AI practice test explains its answers the same way.

  1. Question 1

    At which OSI layer do routers primarily operate?

    1. ALayer 2 (Data Link)
    2. BLayer 3 (Network)
    3. CLayer 4 (Transport)
    4. DLayer 7 (Application)
    Show answer

    Answer: B. Layer 3 (Network)

    Routers forward packets based on IP addresses, which belong to the Network layer. Switches mostly work at Layer 2 with MAC addresses.

  2. Question 2

    How many usable host addresses are in a /24 IPv4 subnet?

    1. A128
    2. B254
    3. C255
    4. D256
    Show answer

    Answer: B. 254

    A /24 has 256 addresses, minus the network address and the broadcast address, leaving 254 usable hosts.

  3. Question 3

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

    1. ADNS
    2. BDHCP
    3. CFTP
    4. DSMTP
    Show answer

    Answer: B. DHCP

    DHCP leases addresses automatically. DNS translates domain names into IP addresses.

How to study for FBLA Networking Infrastructures

Memorize the OSI layers with the devices and protocols at each, plus the common port numbers. Practice subnetting until you can do a /24 to /30 quickly.
