Question 4:

Which two statements about ADDM are true?

A. Real-Time ADDM uses AWR snapshots of the last 10 minutes.

B. Real-Time ADDM uses ASH recent activity from SGA data.

C. Real-Time ADDM analyzes performance in a completely different fashion than regular ADDM.

D. Regular ADDM uses AWR snapshots that are not yet purged.

Correct Answer: CD

C: Real-Time ADDM provides an innovative way to analyze problems in unresponsive or hung databases.

Using a normal and a diagnostic mode connection Real-Time ADDM runs through a set of predefined criteria to analyze the current performance and helps the DBA to resolve deadlocks, hangs, shared pool contentions and many other

exception situations that today forces the administrator to bounce their databases, causing significant loss of revenue. Real-Time ADDM is the only tool available in the market today that can log into a hung database, analyze the problem and

recommend a resolution.

Note: Real-Time ADDM is an innovative way to analyze problems in extremely slow or unresponsive databases, which would have traditionally required a database restart. Real-Time ADDM can help resolve issues such as deadlocks, hangs,

and shared pool contentions, as well as many other exception situations, without resorting to a restart of the database.

D: ADDM builds upon the data captured in AWR.

Question 5:

Which statement about the Oracle Advanced Security Data Redaction feature is true?

A. It transparently encrypts data at rest in Oracle databases.

B. It securely manages encryption keys.

C. It protects against theft or loss of disks and backups.

D. It prevents OS users from inspecting tablespace files.

E. It limits the exposure of sensitive data in applications.

F. It alters data in caches, buffers, and persistent storage.

G. It impacts operational activities such as backup and restore, upgrade and patch, and replication.

Correct Answer: E

Redacting Sensitive Data for Display Data Redaction provides selective, on-the-fly redaction of sensitive data in query results prior to display by applications so that unauthorized users cannot view the sensitive data. It enables consistent redaction of database columns across application modules accessing the same data. Data Redaction minimizes changes to applications because it does not alter actual data in internal database buffers, caches, or storage, and it preserves the original data type and formatting when transformed data is returned to the application. Data Redaction has no impact on database operational activities such as backup and restore, upgrade and patch, and high availability clusters.

A. PROD_NAME size can be increased from five to 10 characters.

B. PROD_ID can be changed from CHAR to NUMBER data type.

C. PROD_RATE size can be changed from NUMBER(4) to NUMBER(6, 2).

D. New columns can be added only if they have a NOT NULL constraint.

E. None of the existing columns can be dropped because they contain data.

Correct Answer: AC

Question 9:

Your customer has two CDBs: one for Production and one for development. You are asked to create a new development PDB (salesdev) from an existing production PDB (salesprd).

Which two options would accomplish this?

A. You copy all the PDBSSEEDdata files from the production CDB into the development CDB and execute this on the development CDB; SQL> CREATE PLUGGABLE DATABASE salesdev ADMIN USER salesdm IDENTIFIED by password;

B. You alter the salesprd source database to open in read-only mode, and start cloning the source database: SQL> ALTER PLUGGABLE DATABASE salesprd OPEN READ ONLY; SQL> CREATE PLUGGABLE DATABASE salesdev FROM salesprd;

C. You alter the salesprd source database to open in read-only mode: SQL> ALTER PLUGGABLE DATABASE salesprd OPEN READ ONLY; In the development CDB, you create a databaselink “PRD” that connects to the root of the source CDB, and start cloning the source PDB: SQL> CREATE PLUGGABLE DATABASE salesdevFROM [email protected];

D. Connected as the salesprd local DBA, you create an XML using: SQL> ALTER PLUGGABLE DATABASE salespdb UNPLUG INTO \’ /tmp/salesprd-xml\’ ; Copy the XML file and all salesprd-related files to the target CDB and start plugging the copy into the development CDB using: SQL> CREATE PLUGGABLE DATABASE salesdev USING\’ /tmp/salesprd.xml\’;

Correct Answer: AD

A: Creating a PDB Using the Seed

You can use the CREATE PLUGGABLE DATABASE statement to create a PDB in a CDB using the files of the seed.

To plug in an unplugged PDB, the following prerequisites must be met:


Complete the prerequisites described in “Preparing for PDBs”.


The XML file that describes the PDB must exist in a location that is accessible to the CDB.
