Match each network application operational requirement or protocol scenario on the left with its corresponding transport layer protocol implementation characteristic on the right.
- Real-time interactive voice communications (VoIP) sensitive to delay variation and jitterUtilizes UDP with a fixed 8-byte header to eliminate transmission delay without transport-layer retransmission
- Border Gateway Protocol (BGP) neighbor relationship establishing routing table synchronizationUtilizes TCP port 179 to enforce connection-oriented state tracking, sequence numbers, and explicit delivery guarantees
- Trivial File Transfer Protocol (TFTP) image download on an embedded network deviceUtilizes UDP port 69, delegating error recovery and lock-step acknowledgments to the application layer to keep transport minimal
- Centralized SNMPv2c polling query retrieving interface counters from high-density switchesUtilizes UDP port 161 to perform lightweight, stateless request-response exchanges without per-session state memory overhead
Cevap
Real-time VoIP pairs with UDP 8-byte low-latency transport; BGP peering pairs with TCP port 179 stateful reliable transport; TFTP image download pairs with UDP port 69 and application-layer ACKs; SNMP polling pairs with UDP port 161 stateless request-response.
Real-time VoIP demands UDP for minimal latency and an 8-byte header; BGP requires TCP on port 179 for reliable ordered routing updates; TFTP uses UDP port 69 and handles reliability at the application layer; SNMP polling uses UDP port 161 for lightweight stateless data collection.
