Developing Applications and Automating Workflows Using Cisco Platforms (DEVASC) — Question 511

An engineer must investigate the problems on a web application and address them to related teams. The engineer verifies the application reachability from the single public IP address with port and discovers that HTTPS access works to three servers of a network farm with IP 172.16.50.1 .2 and .4, but HTTPS access to the server with IP 172.16.50.3 does not work. Which problem type must be addressed as the cause for the case?

Answer options

• A. VPN connectivity
• B. NAT
• C. blocked transport port
• D. proxy

Correct answer: C

Explanation

The correct answer is C, as the server with IP 172.16.50.3 is not reachable via HTTPS, indicating that access to the required transport port may be blocked. Options A, B, and D do not directly relate to the specific issue of HTTPS access being denied to just one server while others are accessible.
