CISSP PRACTICE QUESTIONS – 20211018

Effective CISSP Questions

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.”

A. 網絡功能虛擬化 (NFV) 通常使用專有服務器來運行網絡服務以提高性能。
B. 軟件定義網絡 (SDN) 將通過應用程序編程接口 (API) 進行通信的網絡控制和轉發功能解耦。
C. 軟件定義邊界 (SDP) 利用現有技術(例如 VPN、SDN、微分段等)來加強安全性。
D. 零信任概念可以使用 SDP 來實現。
