CompTIA Cloud+ (CV0-004) — Question 81

Which of the following protocols is often used in IoT to reduce the amount of data exchanged?

Answer options

• A. MQTT
• B. SMB
• C. NFS
• D. HTTPS

Correct answer: A

Explanation

MQTT is specifically designed for low-bandwidth and high-latency environments, making it ideal for IoT applications where minimizing data exchange is crucial. In contrast, SMB and NFS are more suited for file sharing in local networks, while HTTPS is designed for secure web communication, which typically involves larger data payloads.
