Which of the following statements about NFV, SDN, SDP, and Zero Trust is not true? (Wentz QOTD)
A. Network Function Virtualization (NFV) typically uses proprietary servers to run network services for performance.
B. Software-defined networking (SDN) decouples the network control and forwarding functions that communicate through application programming interfaces (APIs).
C. Software Defined Perimeters (SDP) leverages existing technologies, such as VPN, SDN, micro-segmentation, etc. to enforce security.
D. Zero Trust concepts can be implemented using SDP.
Kindly be reminded that the suggested answer is for your reference only. It doesn’t matter whether you have the right or wrong answer. What really matters is your reasoning process and justifications.
My suggested answer is A. Network Function Virtualization (NFV) typically uses proprietary servers to run network services for performance.
Wentz’s book, The Effective CISSP: Security and Risk Management, helps CISSP and CISM aspirants build a solid conceptual security model. It is a tutorial for information security and a supplement to the official study guides for the CISSP and CISM exams and an informative reference for security professionals.
According to Wikipedia, “NFV deployments typically use commodity servers to run network services software versions that previously were hardware-based.”
