• To open up frames

What is the role of a default gateway in a network?

• To enable communication between different networks

• To create IP packets

• To analyze MAC headers

• To open up frames

What is the function of a switch in a network?

• To forward frames based on MAC addresses

• To create IP packets

• To analyze MAC headers

• To open up frames

What does a host do with a received frame?

• Opens it up and checks the MAC address header

• Creates a new frame with a different MAC address

• Sends it out onto the LAN

• Analyzes the IP packet destination

What is the purpose of an IP packet?

• To carry data from source to destination

• To create frames

• To analyze MAC headers

• To open up frames

What information does an IP packet contain?

• Source and destination DNS servers

What does a packet create before it can be sent out onto the Ethernet LAN?

• A frame

• An IP address

• A MAC address

• A switch

What does a switch do with a received frame?

• Sends it out of the port connected to the destination MAC address

• Creates a new frame with a different MAC address

• Analyzes the IP packet destination

• Opens it up and checks the MAC address header

What does a router do with a received frame?

• Analyzes the MAC header and opens up the frame
