Which three statements are true about naming methods? (Choose three.)

Local naming, typically configured in a tnsnames.ora file, allows you to specify connection details for multiple network protocols. However, for a single established connection, both the client and server must utilize the identical network protocol for successful communication.

The Easy Connect naming method allows clients to connect to a database server by using a simple connection string that includes the host name or IP address, an optional port number (defaulting to 1521), and the service name or SID, without needing a local configuration file.

In the Easy Connect method, the listener port is optional if the default port 1521 is used, and the IP address can be substituted with a hostname, meaning not all these elements are strictly mandatory to provide explicitly.

The local naming method, configured in tnsnames.ora, does support connect-time failover and load-balancing options through specific parameters like ADDRESS_LIST, LOAD_BALANCE=on, and FAILOVER=on within the TNS alias definition.

The directory naming method, which uses a centralized LDAP directory server to store network service names, fully supports advanced connection options like connect-time failover and load balancing, enhancing connection reliability and resource distribution.
