Refer to the exhibit. An ACL is configured in the router R1 to prevent telnet traffic from network 192.168.100.56/29 from going out of the Router. However all traffic is being blocked from both networks connected to router R1. What can be done to solve the problem?

The "access-group" command for serial 1/0 must be reconfigured as "in".

The wildcard must be reconfigured to 0.0.0.31.

The command "access-group 1 out" must be reconfigured.

The "command access-list 101 permit ip any any" must be executed as the first line.

Explanation

The interface serial1/0 of router "R1" is assigned to a different access list (1), which might be blocking all the traffic. To make access list 101 work properly for router R1, the command "ip access-group 101 out" must be executed. The ACL should first check the most significant IPs in this case 192.168.15.56/29 must be checked before all the IPs. The line "command access-list 101 permit ip any any" must be issued at the last line of the ACL. The idea of the ACL is to block telnet traffic from going out of the serial interface, so the outbound "out" is properly configured. To allow only the network 192.168.15.56/29 the wildcard 0.0.0.15 must be issued, which in this case is correct.
