Developing Applications and Automating Workflows Using Cisco Platforms (DEVASC) — Question 68

Users cannot access a webserver and after the traffic is captured, the capture tool shows an ICMP packet that reports "communication administratively prohibited". What is the cause of this webserver access issue?

Answer options

• A. An access list along the path is blocking the traffic.
• B. Users must authenticate on the webserver to access it.
• C. A router along the path is overloaded and thus dropping traffic.
• D. The traffic is not allowed to be translated with NAT and dropped.

Correct answer: A

Explanation

The correct answer is A because the ICMP message indicates that an access control list is blocking traffic to the webserver. Options B, C, and D are incorrect as they do not explain the administrative prohibition indicated by the ICMP packet, which specifically suggests a deliberate traffic blockage, rather than issues related to authentication, router overload, or NAT translation.
