A. B. C. D.C.
In this scenario, the administrator is securing a secure web server by disabling some ports, but after completing the process, the clients cannot access the secure web server. So, the administrator needs to verify which port is enabled that is required for accessing the secure web server.
Port 23 is used for Telnet protocol, which is an insecure protocol and should not be used for secure web servers. Hence, it is less likely that port 23 needs to be enabled for accessing a secure web server.
Port 389 is used for LDAP protocol, which is used for directory services. It is not typically used for secure web servers, and it is less likely that port 389 needs to be enabled for accessing a secure web server.
Port 443 is used for HTTPS protocol, which is a secure protocol used for accessing secure web servers. If this port is disabled, clients will not be able to access the secure web server. Hence, the administrator should verify whether port 443 is enabled for accessing the secure web server.
Port 445 is used for SMB protocol, which is used for file sharing services. It is not typically used for secure web servers, and it is less likely that port 445 needs to be enabled for accessing a secure web server.
Therefore, the correct answer is C. 443.
