Question

AMU 2026 — Computer PYQ

AMU | Computer | 2026

The transport layer protocols used for real time multimedia, file transfer, DNS and email, respectively are

Choose the correct answer:

Explanation

To find the correct sequence, we can map each application layer service to its corresponding underlying Transport Layer protocol based on its operational requirements (reliability vs. speed):

Application Service	Transport Protocol	Reason for Protocol Choice
Real-time multimedia	UDP	Video streaming and VoIP prioritize speed and low latency over minor packet loss. A dropped frame is better than a delayed frame.
File transfer (FTP)	TCP	File transfers require absolute accuracy and error-free data delivery. A single missing bit can corrupt the entire file.
DNS (Domain Name System)	UDP	DNS queries need to be lightning-fast. A simple request-response mechanism works perfectly with the low-overhead nature of UDP.
Email (SMTP)	TCP	Email communication mandates reliable, connection-oriented data streaming to prevent data corruption or loss of messages.

Mapping them sequentially in the exact order requested in image_da3873.png:

$Real-time multimedia ⟶ UDP$

$File transfer ⟶ TCP$

$DNS ⟶ UDP$

$Email ⟶ TCP$

This sequential configuration gives the sequence UDP, TCP, UDP, and TCP, which matches option (c) perfectly.
