Which protocol is used by a computer to find the MAC address of the default gateway on an Ethernet network?

ARP

What statement describes the function of the Address Resolution Protocol?

ARP is used to discover the MAC address of any host on the local network

Match each description to its corresponding term

Message encoding - the process of converting information from one format into another acceptable for transmission Message Encapsulation - the process of placing one message format inside another message format Message sizing - The process of breaking up a long message into individual pieces before being sent over the network

What is an advantage of using standards to develop and implement protocols?

Products from different manufacturers can interoperate successfully

Which statement accurately describes a TCP/IP encapsulation process when a PC is sending data to the network?

The VLAN that is used by PC-A is not in the list of allowed VLANs on the trunk

If the default gateway is configured incorrectly on the host, what is the impact on communications?

The host can communicate with other hosts on the local network, but is unable to communicate with hosts on remote networks

What will happen if the default gateway address is incorrectly configured on a host?

The host cannot communicate with hosts in other networks
