  1. What is the standard Ethernet MTU size?

    Answer: 1500 bytes

    The standard Ethernet MTU is 1500 bytes, the maximum payload size of an Ethernet frame.

  2. Which routing protocol uses the Dijkstra algorithm?

    Answer: OSPF

    OSPF is a link-state routing protocol that uses Dijkstra's shortest path first algorithm.

  3. What is the purpose of the ARP protocol?

    Answer: Map IP addresses to MAC addresses

    ARP resolves IPv4 addresses to MAC addresses on a local network segment.

  4. Which topology provides highest fault tolerance but requires the most cabling?

    Answer: Full mesh

    A full mesh topology connects every device directly to every other device.

  5. What is the primary difference between a hub and a switch?

    Answer: Switches forward frames by MAC address while hubs broadcast to all ports

    Switches maintain a MAC address table and forward frames only to the correct port, while hubs broadcast to every port.

  6. Which port number is used by DNS?

    Answer: 53

    DNS uses port 53 for both UDP (standard queries) and TCP (zone transfers).
