B. A query result based on a read-consistent snapshot of data that is older than the latest committed version of the data is not cached.
C. Adding the RESULT_CACHE hint to inline views enables optimizations between the outer query and the inline view, and the query result is cached.

Answer: A,B
Q2. DATA_FILES is a directory object that contains the DETAILS.TXT text file. You have the required permissions to access the directory object.
You create a table using the following command:
CREATE TABLE clob_tab(col2 CLOB);

What correction must be done to ensure the PL/SQL block executes successfully?
A. The L_OUT variable must be initialized to an empty locator. B. The L_OUT variable has to be declared as a temporary LOB. C. The A_CLOB variable has to be declared as a temporary LOB.
D. The clause RETURNING col2 INTO a_clob should be added to the INSERT statement to correctly initialize the locator.
Answer: D
Q3. Which two statements are true about BFILES? (Choose two.)
A. BFILES support only sequential reads.
B. BFILES can be used as attributes in an object type.
C. When LOB is deleted, the corresponding physical file is automatically deleted.
D. The RMAN backup automatically backs up the BFILE locators and the corresponding physical files.

C. Escape single quotes when you use the ENQUOTE_LITERAL procedure.

System altered.
Which statement is true in this scenario?
A. 1056 KB is allocated for the result cache and the result cache is enabled.
