Dell EMC Associate – Backup and Recovery Solutions Design v2 — Question 6

What is true for a software-defined network?

Answer options

• A. physical switches and routers dependent on the underlying network
• B. physical switches dependent on the underlying network
• C. virtual switches dependent on the underlying network
• D. switching and routing of the network traffic independent of the underlying network

Correct answer: D

Explanation

The correct answer is D because a software-defined network allows for the abstraction of network resources, enabling switching and routing to occur independently of the physical infrastructure. Options A, B, and C incorrectly imply a dependence on the physical network, which contradicts the very concept of software-defined networks.
