Answer options

• A. Nonrepudiation
• B. Identity management
• C. Continuity of service
• D. Homogeneity of the network

Correct answer: C

Continuity of service is crucial for VoIP communications, as any interruption can severely impact business operations. While nonrepudiation, identity management, and network homogeneity are important, they do not directly affect the reliability and availability of VoIP services like continuity does.
