CCDE: Cisco Certified Design Expert (Practical) — Question 155

Which three elements help network designers to construct secure systems that protect information and resources (such as devices, communication, and data) from unauthorized access, modification, inspection, or destruction? (Choose three.)

Answer options

• A. scalability
• B. availability
• C. serviceability
• D. integrity
• E. confidentiality
• F. reliability

Correct answer: B, D, E

Explanation

The correct elements are availability, integrity, and confidentiality. Availability ensures that resources are accessible when needed, integrity protects against unauthorized modifications, and confidentiality safeguards sensitive information from unauthorized access. Scalability, serviceability, and reliability, while important for system performance and maintenance, do not directly contribute to the security of information and resources.
