Certified Information Systems Security Professional (CISSP) — Question 404

Which of the following is a MAJOR consideration in implementing a Voice over Internet Protocol (VoIP) network?

Answer options

• A. Use of Request for Comments (RFC) 1918 addressing.
• B. Use of Network Access Control (NAC) on switches.
• C. Use of separation for the voice network.
• D. Use of a unified messaging.

Correct answer: C

Explanation

The correct answer is C because separating the voice network is crucial for ensuring quality and reliability in VoIP communications. Options A and B relate to aspects of network security and addressing, which, while important, are not as critical as network separation for voice traffic. Option D, unified messaging, pertains to communication management rather than the operational integrity of a VoIP network.
