Oracle Database 12c: Installation and Administration — Question 163

Which three statements are true about Enterprise Manager Database Express? (Choose three.)

Answer options

• A. It can be used to perform database backup operations.
• B. It can use the HTTP protocol.
• C. The same port number is used for multiple Database Express configurations on the same host.
• D. It can use the HTTPS protocol.
• E. It is available only when the database is open.

Correct answer: B, D, E

Explanation

The correct answers are B, D, and E because Enterprise Manager Database Express does indeed use both the HTTP and HTTPS protocols, and it is only accessible when the database is open. Option A is incorrect because while backup operations can be performed, they are not a primary feature of Database Express, and option C is incorrect as each Database Express instance requires a unique port number.
