Which port is LDAP?

Explanation:
LDAP uses port 389 as its default communications port, used by directory services to handle queries and updates. It runs over TCP to ensure reliable delivery of requests and responses; when LDAP is secured, the common alternative is port 636 for LDAPS. The other ports shown belong to different services—NFS/RPC-related traffic, SNMP, and HTTPS—so 389 is the correct LDAP port.
