In Huawei's big data solution, LadpServer is used as a directory service system, which can realize centralized management of accounts on the big data platform. Which of the following statement about…

Question

Options

• ALdapServer supports TCP/IP protocol.
• BLdapServer is a specific open source implementation based on the LDAP standard protocol.
• CLdapServer uses Berkelay DB as the default backend database.
• DLdapServer is implemented based on OpenLDAP open source technology.

• A
  100% (27)

Explanation

All four statements are correct, making this an "all of the above" question about Huawei's LdapServer component. A is correct because LDAP operates over TCP/IP (defaulting to port 389), which is foundational to how directory clients and servers communicate across networks. B is correct because LdapServer is an open-source implementation that conforms to the LDAP (Lightweight Directory Access Protocol) standard, enabling interoperability with other LDAP-compliant systems. C is correct because OpenLDAP - and by extension Huawei's LdapServer - historically uses Berkeley DB (BDB/HDB) as its default backend storage engine for persisting directory entries. D is correct because Huawei's LdapServer is built on OpenLDAP open-source technology, rather than being a proprietary implementation from scratch.

Memory tip: Think of the acronym TODD - TCP/IP transport, Open source implementation, Database (Berkeley DB), Derived from OpenLDAP. When you see all four properties listed as choices for LdapServer, remember that they all describe the same technology stack - each is a true characteristic, so selecting all of them is always safe.
