59題、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連接方法如果訪問的是默認端口,可以在連接時忽略;directory 連接方式需要LDAP支持,可以實現failover和load-balance功能。本地命名連接方式可以支持多種協議,但是監聽那邊要有相同的協議進行匹配。)
