Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 309

An engineer creates a default static route on a router with a next hop of 10.1.1.1. On inspection, the engineer finds the router has two VRFs, Red and Blue. The next hop is valid for both VRFs and exists in each assigned VRF. Which configuration achieves connectivity?

Answer options

• A. ip route vrf Red 0.0.0.0 0.0.0.0 10.1.1.1 ip route vrf Blue 0.0.0.0 0.0.0.0 10.1.1.1
• B. ip route vrf BLUE 0.0.0.0 255.255.255.255 10.1.1.1 ip route vrf RED 0.0.0.0 255.255.255.255 10.1.1.1
• C. ip route vrf Red 0.0.0.0 255.255.255.255 10.1.1.1
• D. ip route vrf Blue 0.0.0.0 255.255

Correct answer: A

Explanation

Option A is correct because it sets a default static route for both VRFs, allowing traffic to route properly through the next hop of 10.1.1.1. Option B uses a more specific subnet mask which does not create a default route, while Option C only configures the Red VRF, leaving the Blue VRF without a route. Option D is incomplete and lacks a destination, making it invalid.
