CompTIA Network+ (N10-009) — Question 456

A network engineer receives a new router to use for WAN connectivity. Which of the following best describes the layer the network engineer should connect the new router to?

Answer options

• A. Core
• B. Leaf
• C. Spine
• D. Access

Correct answer: A

Explanation

The correct answer is A, as the Core layer is responsible for high-speed, reliable data transport across the network, making it ideal for WAN connectivity. The Leaf layer serves edge devices, the Spine layer connects different Leaf switches, and the Access layer is for end devices, which are not suitable for WAN connections.
