Q

Data is being sent from a source PC to a destination server. Which three statements correctly describe the function of TCP or UDP in this situation? (Choose three.)

UDP segments are encapsulated within IP packets for transport across the network.

The source port field identifies the running application or service that will handle data returning to the PC.

The TCP source port number identifies the sending host on the network.

TCP is the preferred protocol when a function requires lower network overhead.

The UDP destination port number identifies the application or service on the server which will handle the data.

The TCP process running on the PC randomly selects the destination port when establishing a session with the server.

A

UDP segments are encapsulated within IP packets for transport across the network.

The source port field identifies the running application or service that will handle data returning to the PC.

The UDP destination port number identifies the application or service on the server which will handle the data.

Q

A high school in New York (school A) is using videoconferencing technology to establish student interactions with another high school (school B) in Russia. The videoconferencing is conducted between two end devices through the Internet. The network administrator of school A configures the end device with the IP address 209.165.201.10. The administrator sends a request for the IP address for the end device in school B and the response is 192.168.25.10. Neither school is using a VPN. The administrator knows immediately that this IP will not work. Why?

There is an IP address conflict.

This is a loopback address.

This is a link-local address.

This is a private IP address.

A

This is a private IP address.
