CompTIA Network+ (N10-009) — Question 50

Which of the following ports creates a secure connection to a directory service?

Answer options

• A. 22
• B. 389
• C. 445
• D. 636

Correct answer: D

Explanation

Port 636 is used for LDAP over SSL (LDAPS), which provides a secure method to access a directory service. Port 22 is typically used for SSH, port 389 is used for standard LDAP, and port 445 is used for SMB, none of which offer the same secure connection for directory services as port 636 does.
