A security team is evaluating QKD for a high-security application. They ask: 'What is the fundamental advantage of QKD over classical key exchange methods like Diffie-Hellman?'

QKD does not require any additional hardware, making it easier to deploy than classical methods

QKD is faster than classical key exchange because it uses quantum entanglement

QKD can be used over any distance without loss, unlike classical methods

QKD provides information-theoretic security, meaning it is secure against any computational attack, including quantum computers

Part of the Quantum Computing and Cryptography domain, which makes up ~11% of our current practice bank. EC-Council does not publish an official question count, but from its 120-minute exam (~50–80 total, ~6–9 in this domain), expect 3–5 from this objective — we provide 41 practice questions to prepare you well beyond it.
