CCNA: Cisco Certified Network Associate — Question 916

What is a characteristic of a collapsed-core network topology?

Answer options

• A. It enables all workstations in a SOHO environment to connect on a single switch with internet access.
• B. It enables the core and access layers to connect to one logical distribution device over an EtherChannel.
• C. It allows wireless devices to connect directly to the core layer, which enables faster data transmission.
• D. It allows the core and distribution layers to run as a single combined layer.

Correct answer: D

Explanation

The correct answer is D because a collapsed-core network topology merges the core and distribution layers into one layer, simplifying the architecture. Options A, B, and C describe different functionalities or scenarios that do not specifically characterize the collapsed-core topology, making them incorrect in this context.
