CCNA: Cisco Certified Network Associate — Question 1040
Which type of protocol is VRRP?
Answer options
- A. allows two or more routers to act as a default gateway
- B. uses Cisco-proprietary First Hop Redundancy Protocol
- C. uses a destination IP address 224.0.0.102 for router-to-router communication
- D. uses dynamic IP address assignment
Correct answer: A
Explanation
The correct answer, A, describes VRRP's functionality, which allows multiple routers to share responsibility as a default gateway, ensuring redundancy. Option B is incorrect because VRRP is not a Cisco-specific protocol; it is an open standard. Option C is also wrong as VRRP utilizes multicast IP address 224.0.0.18, not 224.0.0.102. Lastly, option D does not pertain to VRRP, as it does not involve dynamic IP address assignment.
