CompTIA DataX (CNX-001) — Question 51

A user reports an issue connecting to a database server. The front-end application for this database is hosted on the company's web server. The network engineer has changed the network subnet that the company servers are located on along with the IP addresses of the servers. These are the new configurations:
New subnet for the servers is 10.10.10.64/27
Web server IP address is 10.10.10.101
Database server IP is 10.10.10.93
Which of the following is most likely causing the user's issue?

Answer options

• A. The web application server is not forwarding the requests.
• B. The database server firewall is blocking the port to the database.
• C. The DNS server is not resolving properly.
• D. The web server does not have the correct network configuration.

Correct answer: D

Explanation

The web server's network configuration is likely incorrect, which is causing the user to be unable to connect to the database server. Since the network subnet has changed, the web server must also have its configuration updated to reflect the new subnet settings. The other options are less likely because they do not directly address the change in network configuration that could prevent connectivity.
