Q51. Identify two situations in which the alert log file is updated.
A. Running a query on a table returns ORA-600: Internal Error.
B. Inserting a value into a table returns ORA-01722: invalid number.
C. Creating a table returns ORA-00955: name us already in used by an existing objects.
D. Inserting a value into a table returns ORA-00001: unique constraint (SYS.OK_TECHP) violated.
E. Rebuilding an index using ALTER INDEX . . . REBUILD fails with an ORA-01578: ORACLE data block corrupted (file # 14, block # 50) error.
Q52. Your multitenant container (CDB) contains two pluggable databases (PDB), HR_PDB and ACCOUNTS_PDB, both of which use the CDB tablespace. The temp file is called temp01.tmp.
A user issues a query on a table on one of the PDBs and receives the following error: ERROR at line 1:
ORA-01565: error in identifying file ‘/u01/app/oracle/oradata/CDB1/temp01.tmp’
ORA-27037: unable to obtain file status
Identify two ways to rectify the error.
A. Add a new temp file to the temporary tablespace and drop the temp file that that produced the error.
B. Shut down the database instance, restore the temp01.tmp file from the backup, and then restart the database.
C. Take the temporary tablespace offline, recover the missing temp file by applying redo logs, and then bring the temporary tablespace online.
D. Shutdown the database instance, restore and recover the temp file from the backup, and then open the database with RESETLOGS.
E. Shut down the database instance and then restart the CDB and PDBs.
Q53. You are administering a database and you receive a requirement to apply the following restrictions:
1.A connection must be terminated after four unsuccessful login attempts by user.
2.A user should not be able to create more than four simultaneous sessions.
3.User session must be terminated after 15 minutes of inactivity.
4.Users must be prompted to change their passwords every 15 days. How would you accomplish these requirements?
A. by granting a secure application role to the users
B. by creating and assigning a profile to the users and setting the REMOTE_OS_AUTHENT parameter to FALSE
C. By creating and assigning a profile to the users and setting the SEC_MAX_FAILED_LOGIN_ATTEMPTS parameter to 4
D. By Implementing Fine-Grained Auditing (FGA) and setting the REMOTE_LOGIN_PASSWORD_FILE parameter to NONE.
E. By implementing the database resource Manager plan and setting the SEC_MAX_FAILED_LOGIN_ATTEMPTS parameters to 4.

Q55. Examine the parameters for your database instance:
Which three statements are true about the process of automatic optimization by using cardinality feedback?
A. The optimizer automatically changes a plan during subsequent execution of a SQL statement if there is a huge difference in optimizer estimates and execution statistics.
B. The optimizer can re optimize a query only once using cardinality feedback.
C. The optimizer enables monitoring for cardinality feedback after the first execution of a query.
D. The optimizer does not monitor cardinality feedback if dynamic sampling and multicolumn statistics are enabled.
E. After the optimizer identifies a query as a re-optimization candidate, statistics collected by the collectors are submitted to the optimizer.

Q58. Which three statements are true about the working of system privileges in a multitenant control database (CDB) that has pluggable databases (PDBs)?
A. System privileges apply only to the PDB in which they are used.
B. Local users cannot use local system privileges on the schema of a common user.
C. The granter of system privileges must possess the set container privilege.
D. Common users connected to a PDB can exercise privileges across other PDBs.
E. System privileges with the with grant option container all clause must be granted to a common user before the common user can grant privileges to other users.
Q59. You execute the following commands to audit database activities:
SQL > ALTER SYSTEM SET AUDIT_TRIAL=DB, EXTENDED SCOPE=SPFILE;
SQL > AUDIT SELECT TABLE, INSERT TABLE, DELETE TABLE BY JOHN By SESSION WHENEVER SUCCESSFUL;
Which statement is true about the audit record that generated when auditing after instance restarts?
A. One audit record is created for every successful execution of a SELECT, INSERT OR DELETE command on a table, and contains the SQL text for the SQL Statements.
B. One audit record is created for every successful execution of a SELECT, INSERT OR DELETE command, and contains the execution plan for the SQL statements.
C. One audit record is created for the whole session if john successfully executes a SELECT, INSERT, or DELETE command, and contains the execution plan for the SQL statements.
D. One audit record is created for the whole session if JOHN successfully executes a select command, and contains the SQL text and bind variables used.
E. One audit record is created for the whole session if john successfully executes a SELECT, INSERT, or DELETE command on a table, and contains the execution plan, SQL text, and bind variables used.
