Refer to the exhibit. Which statement correctly describes how Router1 processes an FTP request packet that enters interface S0/0/0, and is destined for an FTP server at IP address 172.16.1.5?
The router matches the incoming packet to the statement that is created by access-list 201 permit ip any any command and allows the packet into the router.
The router reaches the end of ACL 101 without matching a condition and drops the packet because there is no statement that was created by access-list 101 permit ip any any command.
The router matches the incoming packet to the statement that was created by the access-list 101 permit ip any 172.16.1.0 0.0.0.255 command, ignores the remaining statements in ACL 101, and allows the packet into the router.
The router matches the incoming packet to the statement that was created by the access-list 201 deny icmp 172.16.1.0 0.0.0.255 any command, continues comparing the packet to the remaining statements in ACL 201 to ensure that no subsequent statements allow FTP, and then the router drops the packet.

51
What can a network administrator do to recover from a lost router password?

boot the router to ROM monitor mode and configure the router to ignore the startup configuration when it initializes
