Which acronym represents the secure version of the directory access protocol used for directory services?

• A. LDAPS
• B. LDAP
• C. DHCP
• D. DNS

Answer: (A)

LDAPS is the secure form of the directory access protocol, implementing LDAP over TLS/SSL. LDAP itself is the standard protocol used to query and modify directory services like Active Directory or OpenLDAP, but without encryption it transmits credentials and data in plaintext. LDAPS adds TLS/SSL encryption, authenticates the server with a certificate, and protects the integrity and confidentiality of directory traffic. The other options aren’t directory access protocols: DHCP handles dynamic IP address assignment, and DNS translates domain names to IP addresses. Sometimes LDAP can also be secured with STARTTLS on the standard LDAP port, but the acronym for the secure variant in this context is LDAPS.
