The correct answer is A. It has a smaller set of operations. B. The client and server communicate using the TCP/IP protocol stack.. LDAP is "lightweight" compared to X.500 because it uses a simpler protocol with fewer operations and operates directly over the TCP/IP network stack instead of the complex OSI stack.

Why each option
LDAP is "lightweight" compared to X.500 because it uses a simpler protocol with fewer operations and operates directly over the TCP/IP network stack instead of the complex OSI stack.
LDAP was designed to be simpler and more accessible than X.500. One key aspect of this simplification is a significantly reduced and streamlined set of operations, making it easier to implement and use.
X.500 relied on the complex and multi-layered OSI protocol stack, which was cumbersome. LDAP, in contrast, was designed to operate directly over the widely adopted TCP/IP protocol stack, making it much easier to deploy and integrate with existing network infrastructures.
This is incorrect; LDAP uses TCP/IP, whereas X.500 used the OSI protocol stack.
Both LDAP and X.500 (specifically, X.500 directories like DAP) support Access Control Lists for securing directory data. LDAP's ACLs are generally simpler to configure.
