CompTIA Security+ (SY0-701) — Question 229

Which of the following considerations is the most important regarding cryptography used in an IoT device?

Answer options

• A. Resource constraints
• B. Available bandwidth
• C. The use of block ciphers
• D. The compatibility of the TLS version

Correct answer: A

Explanation

Resource constraints are critical in IoT devices due to their limited processing power and battery life, making efficient cryptography essential. While available bandwidth, block ciphers, and TLS version compatibility are relevant, they are secondary to ensuring that the cryptographic methods do not overwhelm the device's resources.
