An engineer must filter incoming EIGRP updates to allow only a set of specific prefixes. The distribute list is tested, and it filters out all routes except network 10.10.10.0/24. How should the engineer temporarily allow all prefixes to be learned by the routers again without adjusting the existing access list?

• A.A continue statement should be added within the permit 10 statement before completing the ACL with the required prefixes, and then the continue statement can be removed.
• B.An extended access list must be used instead of a standard access list to accomplish the task
• C.A permit any statement should be added before completing the ACL with the required prefixes and then the permit any statement can be removed.
• D.A permit 20 statement should be added before completing the ACL with the required prefixes, and then the permit 20 statement can be removed.
