CompTIA Server+ (SK0-004) — Question 59

An administrator is setting up LDAP in the environment to allow directory services authentication and login, and wants to allow secure connection only. Which of the following network ports should be allowed on the internal and external firewalls?

Answer options

• A. 443
• B. 989
• C. 3268
• D. 3389

Correct answer: C

Explanation

Port 3268 is used for the Global Catalog service in Active Directory, which is necessary for LDAP authentication when secure connections are required. Ports 443 and 989 are typically used for HTTPS and FTPS respectively, while port 3389 is for Remote Desktop Protocol, making them unsuitable for LDAP's secure connection needs.
