Explanation

Installing a FusionInsight HD cluster in safe mode means enabling security features, which specifically requires identity authentication (LDAP Server, option B) and Kerberos-based authentication (Krb Server, option C) - these two components form the security foundation that "safe mode" is built upon. LDAP provides the directory service for user account management, while Kerberos (Krb Server) handles ticket-based authentication to prevent unauthorized access across cluster services.

ZooKeeper (A) and HDFS (D) are core infrastructure components required in all cluster modes, not specific to safe mode - they're prerequisites regardless of security configuration, so they don't distinguish safe mode from a standard installation.

Memory tip: Think "safe = security" - the two safe-mode-specific components are the two security services: LDAP (identity store) + Kerberos (authentication). Everything else (ZooKeeper, HDFS) is just standard cluster plumbing you always need.
