Refer to the exhibit. BGP is configured in the network. A network engineer must implement a route filtering policy to manipulate traffic flow between BGP peers. Traffic that matches access list 12 and

Implementing the 'continue' clause within sequence 10 (which matches access-list 12) allows the route-map to proceed and evaluate subsequent sequences, specifically sequence 20 (matching prefix-list 1). This ensures that both match conditions (access-list 12 AND prefix-list 1) can be checked before the 'set metric 200' action in sequence 30 is applied to the routes that satisfy both criteria, fulfilling the requirement.

Implementing a new sequence number between 10 and 20 to set the metric to 200 would apply the metric prematurely if only access-list 12 is matched, without checking for a match against prefix-list 1, thus not meeting the 'both match' requirement.

Implementing a 'set' command within sequence 10 to set the metric to 200 would apply the metric if only access-list 12 is matched. This would bypass the check for prefix-list 1 and not achieve the desired 'AND' logic for both conditions.

Implementing a new sequence number between 10 and 20 to match access-list and prefix-list 1 would not resolve the issue as route-maps evaluate sequences in order; a single sequence matching both would be effective, but inserting it between 10 and 20 without `continue` on 10 or 20 would still not achieve the desired flow if using separate match statements.
