Question 370
At Garden Hall, an AOS-CX distribution switch has a static default route pointing at an unreachable next hop. Which TWO responses together provide a direct implementation and a continuing safeguard for the stated risk? Select TWO answers.
Explanation
Correct Answers
This is the continuing risk-control element for Garden Hall. Keep route rollback and reachability checks before gateway migrations prevents a future regression or unauthorized relaxation of the repair; it complements, rather than replaces, the implementation.
This is the implementation element for the Garden Hall case: A static route only forwards as intended when its next hop can be resolved. The specific action Install a valid static route with a resolvable next hop and appropriate administrative distance addresses the stated fault; the question also requires a persistent risk control.

This may be a configuration step for IPv6 OSPFv3 adjacency: OSPFv3 exchanges IPv6 routing information through a separately configured protocol process. It does not resolve the Static route next hop requirement in Garden Hall and is not one of the two controls requested. The direct mechanism here is a static route only forwards as intended when its next hop can be resolved
This may be an ongoing precaution for DHCP relay return routing: DHCP relay requires a valid return path to the relay address and client network. It does not resolve the Static route next hop requirement in Garden Hall and is not one of the two controls requested. The direct mechanism here is a static route only forwards as intended when its next hop can be resolved
