A network administrator is configuring a low-latency network telemetry application that uses UDP to transmit continuous system performance metrics. Which of the following operational characteristics distinguish connectionless transport protocols from connection-oriented protocols in this implementation? (SELECT TWO)
- Transmission of data packets without requiring an initial session establishment handshakeCevap
- Omission of header fields for sequence numbers, acknowledgment tracking, and window sizeCevap
- CDynamic modification of sliding window sizes to perform network congestion control
- DGuaranteed in-order reassembly of payload segments at the destination transport layer
- EAutomatic retransmission of missing segments triggered by acknowledgement timeouts
Cevap
Connectionless protocols such as UDP transmit data without establishing a prior connection handshake and utilize minimalistic headers that omit sequence numbers, acknowledgments, and flow control fields.
Connectionless protocols transmit data statelessly without performing a handshake to set up a connection before transmission. Furthermore, their headers are lightweight because they lack mechanisms for sequence tracking, arrival acknowledgments, and windowing-based flow control.
