Question 1

In the OEM,when you select the option button beside a datafile in the list and click the Edit button,the Edit Datafile property page opens,which allows you to edit properties of the datafile that is currently selected.

Accepted Answer

This statement accurately describes the functionality of the Edit button in the OEM when used with a selected datafile.

Question 2

The Oracle Database Configuration Assistant is a utility that allows DBAs to configure client workstations so they can connect to database servers using Oracle Net.

Accepted Answer

The Oracle Database Configuration Assistant (DBCA) is primarily used for creating, configuring, and deleting databases on the server side, not for configuring client workstations for Oracle Net connections.

Question 3

The database server stores the data for each tablespace in an extent.

Accepted Answer

A tablespace consists of one or more files or chunks of storage called datafiles, which physically store the data. An extent is a specific set of contiguous data blocks allocated within a tablespace for storing a specific type of data, such as table data or index data, not the data for the entire tablespace.

Question 4

To install any Oracle 10g product,you use Oracle Universal Installer (OUI).

Accepted Answer

Oracle Universal Installer (OUI) is the tool used to install any Oracle 10g product.

Question 5

In Oracle 10g database administration terminology,a database storage data block is the smallest storage unit that the database can address.

Accepted Answer

In Oracle 10g, a database storage data block is indeed the smallest storage unit that the database can address. It is typically 8KB in size and is used to store a specific number of rows for each database table.

Question 6

If you need to change the privileges of the users to whom the role has been granted,you simply change the role's privileges,and the user accounts automatically reflect the privilege change.

Accepted Answer

When a role's privileges are changed, any user accounts that have been granted that role will automatically reflect the privilege change. This is one of the benefits of using roles in database security management.

Question 7

Tablespaces in the Oracle 10g Release 1 database use dictionary-managed extent management,in which the tablespace maintains a bitmap in each datafile that represents whether each data block is free or used.

Accepted Answer

In Oracle 10g Release 1, tablespaces can use either dictionary-managed or locally managed extent management. In locally managed tablespaces, a bitmap is used to manage the free and used space within each datafile, not in dictionary-managed tablespaces. Dictionary-managed tablespaces rely on data dictionary tables to track space usage.

Question 8

The DBA must explicitly connect to the OEM by specifying a username,password,and connect role.

Accepted Answer

To connect to the Oracle Enterprise Manager (OEM), the DBA must provide a valid username, password, and connect role. This is necessary for the OEM to authenticate and authorize the user to perform administrative tasks.

Question 9

For an UPDATE action query,the redo log file contains a pre-image of the updated fields,which shows the data values before the update.

Accepted Answer

The redo log file in Oracle Database contains a pre-image of the modified data block, showing the data values before the update. This information is used during database recovery and in case of a rollback or undo operation.

Question 10

The OEM must be installed using the Universal Installer after installing a database.

Accepted Answer

The Oracle Enterprise Manager (OEM) is a separate tool that can be used to manage Oracle databases and other Oracle software. It does not require the Universal Installer for its installation; it can be installed and configured independently of the database software.

Question 11

The exact steps for installing an Oracle 10g database are the same for all three versions.

Accepted Answer

The installation steps for Oracle 10g database differ between the Enterprise, Standard, and Standard One versions.

Question 12

By default,an Oracle 10g database instance has two separate control files.

Accepted Answer

The answer of By default,an Oracle 10g database instance has...

Question 13

To enable a new user to create new database objects,you must assign to the user account a tablespace quota for the user's default tablespace.

Accepted Answer

A tablespace quota specifies the amount of space a user can use within a specific tablespace. To create new database objects, the user must have sufficient space to store them. Therefore, assigning a tablespace quota for the user's default tablespace is necessary to enable the creation of new database objects.

Question 14

The global database name is based on the database server workstation's Internet Protocol (IP)address or domain name.

Accepted Answer

The global database name is based on the database server workstation's Internet Protocol (IP) address or domain name.

Question 15

The DBMS is the same as the database that stores the actual data values.

Accepted Answer

The Database Management System (DBMS) is a software application that is used to manage, manipulate, and access data stored in a database. The DBMS is not the same as the database itself, which is the actual physical or logical location where the data is stored.

Question 16

To use OEM to create a new user account,you navigate to the Administration property page,click the Users link under the Security heading,and then click Create.

Accepted Answer

To use OEM to create a new user account, you navigate to the Administration property page, click the Users link under the Security heading, and then click Create.

Question 17

Disk groups are managed by a special Oracle instance,called an OEM instance.

Accepted Answer

Disk groups are managed by an Oracle ASM instance, not an OEM instance.

Question 18

A connect descriptor specifies the network communication protocol,the IP address of the database server,and the database instance name.

Accepted Answer

A connect descriptor includes information about the network protocol used to establish a connection with the database server, the IP address or hostname of the server, and the name of the database instance to connect to. This information is necessary for a client application to establish a connection with the database server.

Question 19

The parameter file is a text file that specifies configuration information about an Oracle 10g database instance.

Accepted Answer

The parameter file, also known as the initialization file or init.ora file, is a text file that contains configuration settings for an Oracle database instance. It is used during startup to set various parameters such as memory allocation, file paths, and database options.

Question 20

An object privilege allows a user to perform a specific task with the Oracle 10g database,such as connecting to the database or creating a new table.

Accepted Answer

An object privilege allows a user to perform a specific task on a specific database object, such as SELECT, INSERT, UPDATE, or DELETE on a table, but not to connect to the database or create a new table. The SYSTEM privilege is required to perform these tasks.
