200-301 · Question #1099
Refer to the exhibit. The New York router must be configured so that traffic to 2000::1 is sent primarily via the Atlanta site, with a secondary path via Washington that has an administrative distance
The correct answer is A. ipv6 route 2000::1/128 2012::1 E. ipv6 route 2000::1/128 2023::3 2. The New York router requires two static IPv6 routes for 2000::1: a primary route to Atlanta with the default administrative distance of 1, and a secondary route to Washington with an administrative distance of 2.

Why each option
The New York router requires two static IPv6 routes for 2000::1: a primary route to Atlanta with the default administrative distance of 1, and a secondary route to Washington with an administrative distance of 2.
This command establishes the primary static IPv6 route for the destination 2000::1/128 via the next-hop 2012::1, utilizing the default administrative distance of 1, which is preferred over paths with higher administrative distances.
This command assigns an administrative distance of 5, which would make it less preferred than both the required primary path (AD 1) and the secondary path (AD 2).
While a static route with AD 1, the next-hop 2012::2 is not the one chosen in the correct answer set for the Atlanta site.
This command assigns an administrative distance of 5 for the Washington path, which does not meet the requirement for a secondary path with an administrative distance of 2.
This command configures the secondary static IPv6 route for 2000::1/128 via the next-hop 2023::3, with a specified administrative distance of 2, ensuring it is used only if the primary path (with AD 1) becomes unavailable.
