CCDE: Cisco Certified Design Expert (Written) — Question 37

You have been tasked to create a Layer 2 network design that uses vPC to provide resiliency and avoid loops. vPC removes Layer 2 loops while providing redundancy through which mechanism?

Answer options

• A. dual-active detection
• B. address synchronization
• C. strict forwarding rules
• D. Bridge Assurance

Correct answer: C

Explanation

The correct answer is C, as strict forwarding rules are essential for vPC to prevent loops while maintaining redundancy. Options A and D pertain to other aspects of redundancy and loop prevention but do not directly relate to the mechanism employed by vPC. Option B, address synchronization, is more about maintaining consistency between devices rather than directly addressing loop prevention.
