Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 9

A client with IP address 209.165.201.25 must access a web server on port 80 at 209.165.200.225. To allow this traffic, an engineer must add a statement to an access control list that is applied in the inbound direction on the port connecting to the web server.
Which statement allows this traffic?

Answer options

• A. permit tcp host 209.165.200.225 lt 80 host 209.165.201.25
• B. permit tcp host 209.165.201.25 host 209.165.200.225 eq 80
• C. permit tcp host 209.165.200.225 eq 80 host 209.165.201.25
• D. permit tcp host 209.165.200.225 host 209.165.201.25 eq 80

Correct answer: C

Explanation

The correct answer is C because it specifies the source address of the web server and allows traffic on port 80 from the client. Option A is incorrect as it uses 'lt 80', which does not match the required port, while B incorrectly indicates the source and destination. Option D is also incorrect because it does not specifically denote the port as equal to 80 for the correct traffic direction.
