access-list 101 deny tcp 172.16.3.0 0.0.0.255 any eq 21
access-list 101 permit ip any any

FTP traffic originating from network 172.16.3.0/24 is denied.

All traffic is implicitly denied.

FTP traffic destined for the 172.16.3.0/24 network is denied.

Telnet traffic originating on network 172.16.3.0/24 is denied.
Web traffic originating from 172.16.3.0 is permitted.


10
Which statement applies to a large network with thousands of nodes?

Each wireless phone is normally in a separate VLAN for security reasons.

Multiple firewalls exist throughout the access layer for maximum security protection.

Firewalls cannot be implemented in the multilayer switches and routers.

Intrusion detection is more likely to be performed by a separate device rather than integrated into a switch or router


11
