Which three statements are true about the naming methods and their features supported by Oracle database used to resolve connection information? (Choose three.)
A client can connect to an Oracle database instance with Easy Connect even if no client-side network admin has been configured. Directory Naming can be used if Connect-Time Failover is required. Local Naming also supports Connect-Time Failover when the tnsnames.ora file is properly configured.
I will go for ABE
I think BCE. B - Easy Connect requires no client-side configuration. C - Local Naming supports the advanced connection option Connect-time failover. E - Directory Naming supports Connect-time failover.
MOS note "Does EZCONNECT work with SSL / TCPS? ORA-12547 is received with 18c and below. (Doc ID 2502638.1)" states that from 19c and above, we now have an option for TCPS (TLS) with Easy Connect Plus.
Yes. Protocol The protocol specifies the transport protocol to be used while connecting to the database host. From 19c, the supported values are TCP and TCPS. The default is TCP. https://download.oracle.com/ocomdocs/global/Oracle-Net-Easy-Connect-Plus.pdf 5/15
Quote: Net Service Administrator Guide "Note: Easy Connect Plus feature" https://docs.oracle.com/en/database/oracle/oracle-database/19/netag/configuring-naming-methods.html#GUID-966E77E9-7A50-4A24-88CD-91B3578EDEA8
BCE correct
D is wrong because Easy Connect only support TCP/IP
before 19c
I think : A,B,E
A,B,C i have checked because local naming relies on tnsnames.ora file
ABF I think
