A global company plans to implement BGP at its newest location to provide connectivity to other offices. The global infrastructure of the company is a multivendor environment. An engineer must review the BGP core configurations at headquarters to determine if they can be repurposed at the new location. The engineer copied this JSON script for review. What is the effect of the script?

1. A. It configures BGP with neighbor 192.168.1.2 residing in AS 65514.
2. B. It sets the BGP router-ID to 192.168.1.2 and sets the AS of the router to 65514.
3. C. It configures BGP on the device and inserts 192.168.1.0/24 into the BGP table using the origin AS 65514.
4. D. It configures a VRF named cisconode1 and a BGP instance using the VPNv4 address family.

Correct Answer: A
