Certified Information Systems Security Professional (CISSP) — Question 348

A company is planning to implement a private cloud infrastructure. Which of the following recommendations will support the move to a cloud infrastructure?

Answer options

• A. Implement software-defined networking (SDN) to provide the ability to apply high-level policies to shape and reorder network traffic based on users, devices and applications.
• B. Implement a virtual local area network (VLAN) for each department and create a separate subnet for each VLAN.
• C. Implement software-defined networking (SDN) to provide the ability for the network infrastructure to be integrated with the control and data planes.
• D. Implement a virtual local area network (VLAN) to logically separate the local area network (LAN) from the physical switches.

Correct answer: A

Explanation

The correct answer, A, highlights the role of software-defined networking (SDN) in managing network traffic effectively, which is crucial for a cloud infrastructure. Options B, C, and D, while relevant to network management, do not specifically address the high-level policy application needed for cloud environments, making them less suitable recommendations.
