| Question ID 21408 | Which statement is True?
|
| Option A | A connect descriptor maps to a service name.
|
| Option B | A service name maps to a connect descriptor.
|
| Option C | A connect descriptor translates only one service name.
|
| Option D | A connect descriptor is an entity unrelated to a service name.
|
| Correct Answer | B |
Explanation Explanation: Answer B is correct. A service name can map only to a connect descriptor. In order for Net8 to recognize the connect string you provide as a valid representation for a database somewhere on the network, your connect string must map to a connect descriptor, which is a description of the Oracle service you want to connect to. Incorrect Answers: A is incorrect; a service name maps to a connect descriptor, not vise-versa. C is incorrect; a connect descriptor translates not only one service name. D is incorrect; connect descriptor is an entity highly related with a service name.
