Question

What port does LDAP use?
a) 25
b) 443
c) 389
d) 3389

Answer 1

LDAP typically uses port 389 for non-encrypted communications. Port 25 is used for SMTP, port 443 for HTTPS, and port 3389 for RDP.

Step-by-step explanation:

The question is asking about the network port number that the Lightweight Directory Access Protocol (LDAP) uses for communications without Transport Layer Security (TLS). The correct answer is c) 389. LDAP is a protocol used to access and manage directory services over an IP network, and it commonly uses port 389 for non-encrypted communication, while it can use port 636 when secured via TLS/SSL. On the other hand, port 25 is typically used for SMTP (email), port 443 for HTTPS (secure web traffic), and port 3389 for RDP (Remote Desktop Protocol).
