Identify two prerequisites for configuring Enterprise Manger Database Express (EM Express).
The correct answer is C. Use the DBMS_XDB_CONFIG.SETHTTPPORT procedure to configure a port number for Oracle D. Configure at least one dispatcher for the TCP/IP protocol. EM Express is a lightweight web-based tool that uses Oracle XML DB's built-in HTTP listener rather than a full Oracle HTTP Server. It requires a configured HTTP port and at least one TCP/IP dispatcher to handle incoming connections.
Question
Identify two prerequisites for configuring Enterprise Manger Database Express (EM Express).
Options

Why each option
EM Express is a lightweight web-based tool that uses Oracle XML DB's built-in HTTP listener rather than a full Oracle HTTP Server. It requires a configured HTTP port and at least one TCP/IP dispatcher to handle incoming connections.
APEX_PUBLIC_USER is a role used by Oracle Application Express (APEX) and has no relevance to EM Express authentication or configuration.
EM Express uses the lightweight HTTP listener built into Oracle XML DB and does not require the separate Oracle HTTP Server (OHS), which is needed for EM Cloud Control.
The DBMS_XDB_CONFIG.SETHTTPPORT procedure configures the port on which Oracle XML DB's HTTP listener accepts EM Express connections; without a port assigned, the EM Express URL cannot be reached.
EM Express relies on Oracle Shared Server dispatchers using the TCP/IP protocol to route client requests; at least one dispatcher must be configured, typically by setting DISPATCHERS in the initialization parameters.
The SYSMAN account is the repository owner for Oracle Enterprise Manager Cloud Control, not EM Express; EM Express uses existing database accounts such as SYSTEM or accounts with the DBA role.
