Implementing Automation for Cisco Enterprise Solutions (ENAUTO) — Question 102

What is an advantage of software-defined networks as compared to traditional networks?

Answer options

• A. They simplify operations by creating a concrete copy of the network.
• B. They reduce complexity by coupling the control and the data plane.
• C. They enable older hardware to be repurposed without an investment in new infrastructure.
• D. They deliver a distributed management architecture that provides better resilience to errors.

Correct answer: C

Explanation

The correct answer, C, highlights that software-defined networks can utilize existing hardware, saving costs on new infrastructure. Option A is incorrect as SDNs do not create a physical copy of the network. Option B is misleading because while SDNs do separate the control and data planes, it does not inherently reduce complexity. Option D, while true, does not address the specific advantage of reusing older hardware.
