Palo Alto Networks Cybersecurity Entry-Level Technician (PCCET) — Question 16

Which technique changes protocols at random during a session?

Answer options

• A. use of non-standard ports
• B. port hopping
• C. hiding within SSL encryption
• D. tunneling within commonly used services

Correct answer: B

Explanation

Port hopping is the correct answer because it specifically refers to the practice of changing communication ports during a session to evade detection. The other options do not involve changing protocols randomly; for instance, using non-standard ports and tunneling involve different methods of securing or disguising traffic but do not imply random changes in protocols.
