CompTIA CASP+ (CAS-003) — Question 173

A security administrator adding a NAC requirement for all VPN users to ensure the connecting devices are compliant with company policy. Which of the following

items provides the HIGHEST
assurance to meet this requirement?

Answer options

• A. Implement a permanent agent.
• B. Install antivirus software.
• C. Use an agentless implementation.
• D. Implement PKI.

Correct answer: D

Explanation

Implementing PKI provides the highest level of assurance because it facilitates strong authentication and secure communications, ensuring devices adhere to compliance standards. A permanent agent, while useful, may not guarantee compliance as effectively as PKI. Antivirus software and agentless implementations do not provide the same level of confidence in verifying device compliance.
