The correct answer is D. The web server does not have the correct network configuration. With a /27 mask on 10.10.10.64/27, valid host addresses run from 10.10.10.65 through 10.10.10.94. The database server's IP (10.10.10.93) is in that range, but the web server's IP (10.10.10.101) falls outside it--so it's mis-configured and cannot reach the database.
