59题、choose three
Which three statements are true about naming methods?
A) In the Easy Connect method, clients can connect to a database server by using the host name of the database with an optional port and service name.
B) The local naming method does not support connect-time failover and load-balancing options.
C) The directory naming method supports connect-time failover and load-balancing options.
D) Local naming supports multiple protocols, but for any one connection, the client and server must use the same protocol.
E) In the Easy Connect method, the listener port and IP address must be provided for the connection to be successful.
Answer:AD
(解析:easy连接方法如果访问的是默认端口,可以在连接时忽略;directory 连接方式需要LDAP支持,可以实现failover和load-balance功能。本地命名连接方式可以支持多种协议,但是监听那边要有相同的协议进行匹配。)
