Option D suggests adding a second sequence in the route map with "permit 20." This would indeed permit routes for the 1.1.1.0/24 network, but the existing deny sequence (sequence number 10) is still present. In Cisco IOS route-maps, the first match is applied. Since the deny statement comes before the permit statement in the route-map, the deny will take precedence. Therefore, even if you add a second sequence with "permit 20," the deny sequence with "deny 10" is still in effect, and the routes for 1.1.1.0/24 would continue to be denied. To achieve the desired result of allowing routes for 1.1.1.0/24 while still filtering other routes, you need to modify the existing deny sequence to permit the desired network. Option B correctly suggests modifying the route-map to permit the access list instead of denying it, effectively allowing routes for 1.1.1.0/24.

wrong. "Which action restores the routes from neighbors while still filtering 1.1.1.0/24?" Wuestion wants to filter out 1.1.1.0/24 and allow other routes. We add sequence 20 to route map, with no match, to allow everything.

To restore the routes from neighbors while still filtering 1.1.1.0/24, you should modify the route-map to permit the routes instead of denying them. Therefore, the correct answer is: B. Modify the route map to permit the access list instead of deny it.
