Which of the following access-list commands permits packets going to any web client from all web servers whose IP addresses begin with 172.16.5?

• access-list 101 permit tcp host 10.1.1.1 172.16.5.0 0.0.0.255 eq www
• access-list 1951 permit ip host 10.1.1.1 172.16.5.0 0.0.0.255 eq www
• access-list 2523 permit tcp any eq www 172.16.5.0 0.0.0.255
• access-list 2523 permit tcp 172.16.5.0 0.0.0.255 eq www 172.16.5.0 0.0.0.255
• access-list 2523 permit tcp 172.16.5.0 0.0.0.255 eq www any

Explanation: Because the packet is going toward any web client, you need to check for the web server’s port number as a source port. The client IP address range is not specified in the question, but the servers are, so the source address beginning with 172.16.5 is the correct answer.
