Host to host communication in networking — Quiz

Host to host communication in networking

1. What is the primary purpose of the Address Resolution Protocol (ARP) in host-to-host communication? (Choose one answer)

a) To resolve a domain name to an IP address

b) To resolve an IP address to a MAC address

c) To determine if a destination host is on the local or a foreign network

d) To configure a host's default gateway IP address

2. When Host A (on network 10.1.1.0/24) wants to send data to Host C (on network 192.168.1.0/24), what destination MAC address does Host A use in the Layer 2 header of the data packet? (Choose one answer)

a) The MAC address of Host C

b) The MAC address of its local switch

c) The MAC address of its default gateway (router)

d) The broadcast MAC address (ffff.ffff.ffff)

3. How is an ARP request frame sent onto the network? (Choose one answer)

a) Unicast to the specific target host's IP address

b) Multicast to a specific group of devices

c) Broadcast to all devices on the local network

d) Anycast to the nearest available device

4. A host determines if a destination IP address is on its local network or a foreign network by (Choose one answer)

a) Sending an ARP request for the destination IP

b) Comparing its own IP and subnet mask to the destination IP

c) Checking the destination's MAC address in its ARP cache

d) Pinging its configured default gateway

5. What is the key difference between the Layer 2 header of an ARP request and the Layer 2 header of the subsequent data packet sent between two hosts on the same network? (Choose one answer)

a) The ARP request uses the sender's IP address, while the data packet uses the destination's IP address

b) The ARP request has a broadcast destination MAC address (all F's), while the data packet has the specific host's unicast MAC address

c) The data packet includes a subnet mask, while the ARP request does not

d) The ARP request is routed, while the data packet is switched
