Question 28

Easy

An automated weather station transmits climate data back to a central research database. To optimize network performance, the transmission system is designed such that high-priority core configuration file transfers use a protocol that guarantees packet delivery and order ( $T C P$ ), while rapid wind speed telemetry updates use a protocol that prioritizes low latency and speed over reliability ( $U D P$ ). The packets are subsequently routed across the internet using the Internet Protocol ( $I P$ ).

Which of the following correctly identifies the TCP/IP model layers at which these three protocols ( $T C P$ , $U D P$ , and $I P$ ) operate?

Both $T C P$ and $U D P$ operate at the Transport layer; $I P$ operates at the Network layer.

$T C P$ operates at the Transport layer; $U D P$ operates at the Application layer; $I P$ operates at the Network layer.

Both $T C P$ and $U D P$ operate at the Network layer; $I P$ operates at the Transport layer.

$T C P$ operates at the Application layer; $U D P$ operates at the Transport layer; $I P$ operates at the Link layer.
