Question 240
A network upgrade at Cascade Health has two requirements: (1) ensure a backup static route does not override a directly connected route to the same prefix, and (2) interpret an L entry for a router's own IPv4 interface address. Which plan correctly handles both requirements?
Explanation
Correct Answer
Both outcomes are covered: (1) Connected routes have distance 0 and normally beat ordinary or floating static alternatives. (2) Local routes identify IP addresses assigned to the router itself. Neither action is a substitute for the other.
Incorrect Answers
The first step covers (1), but the second addresses configure an IPv6 default route over a known link-local next hop. The egress interface is required to disambiguate a link-local next-hop address. It leaves outcome (2) unfulfilled.
The second step covers (2), but the first addresses choose between OSPF routes for the same prefix learned from two paths. Within one protocol and destination prefix the protocol metric selects preferred path cost. It leaves outcome (1) unfulfilled.
Neither step is the requested pair: Deliver it to the local protocol stack rather than remote routing is for forward an IP packet arriving for the router's local interface address, and Give the backup static route AD higher than OSPF's 110 is for provide a static backup only if an OSPF route to the same prefix disappears. A local host route represents the router's own address, not a remote network. The proposed plan misses the two stated outcomes.
