CCNA: Cisco Certified Network Associate — Question 295

Which function is performed by the collapsed core layer in a two-tier architecture?

Answer options

• A. enforcing routing policies
• B. marking interesting traffic for data policies
• C. applying security policies
• D. attaching users to the edge of the network

Correct answer: A

Explanation

The correct answer is A, as the collapsed core layer is primarily responsible for enforcing routing policies to manage data flow. Options B, C, and D do not accurately describe the primary function of the collapsed core layer, which focuses specifically on routing rather than traffic marking, security applications, or user attachment.
