Which two are true about creating tables in an Oracle database?

Regarding creating tables in an Oracle database:

B . The same table name can be used for tables in different schemas: In Oracle, a schema is

essentially a namespace within the database; thus, the same table name can exist in different

schemas without conflict, as each schema is distinct.

C . A system privilege is required: To create tables, a user must have the necessary system privileges,

typically granted explicitly or through roles such as CREATE TABLE or administrative privileges

depending on the environment setup.

Incorrect options for all three repeated questions:

A: Oracle SQL does not allow specifying the maximum number of rows directly in a CREATE TABLE

statement; this is controlled by storage allocation and database design rather than table creation

syntax.

D: Creating an external table does not create the physical file. It merely creates a table structure that

allows access to data stored in an external file specified in the directory; the file itself must already

exist or be managed outside of Oracle.

E: A primary key constraint is not mandatory for creating tables. While it is a common practice to

define a primary key to enforce entity integrity, it is not required by the Oracle SQL syntax for table

creation.

These answers and explanations are aligned with Oracle Database 12c SQL documentation and

standard practices.
