CompTIA Network+ (N10-008) — Question 579

Which of the following architectures would allow the network-forwarding elements to adapt to new business requirements with the least amount of operating effort?

Answer options

• A. Software-defined network
• B. Spine and leaf
• C. Three-tier
• D. Backbone

Correct answer: A

Explanation

The Software-defined network (SDN) architecture allows for centralized control and programmability, making it easier to adapt to new business requirements without extensive manual configuration. In contrast, Spine and leaf, Three-tier, and Backbone architectures are more rigid and typically require more effort to implement changes due to their hierarchical and physical design constraints.
