Oracle Database 23ai Administration Associate Sample Questions (Q91-Q96):

NEW QUESTION # 91
Which two statements are true about database instances and Real Application Clusters (RAC)?

A. A RAC database can have instances on separate servers.
B. A RAC database must have two or more instances.
C. Two RAC databases can share their instances.
D. A RAC database can have one instance.
E. A RAC database must have three or more instances.

Answer: A,D

Explanation:
A .False. RAC can run with one instance (degraded mode).
B .True. Possible, though not typical for RAC.
C .False. No minimum of three.
D .True. RAC instances run on separate nodes.
E .False. Instances are DB-specific in RAC.

NEW QUESTION # 92
What are Oracle Database Metrics?

A. Oracle Database Metrics are part of Oracle Enterprise Manager Cloud Control's Notification system used to email alerts.
B. Oracle Database Metrics are part of the Oracle Database Notification system to email information about major database events.
C. Oracle Database Metrics are a set of statistics built in Oracle Enterprise Manager Cloud Control and used for automation.
D. Oracle Database Metrics are a set of measured statistics per unit of time (per second), transaction, or sessions that are used to evaluate performance.
E. Oracle Database Metrics monitor performance using thresholds to generate alerts.

Answer: D,E

Explanation:
A .True. Metrics (e.g., V$SYSMETRIC) use thresholds for alerts.
B .False. Metrics aren't tied to email notifications directly.
C .True. Metrics measure rates (e.g., IOPS, transactions/sec).
D .False. EMCC uses metrics, but they're DB-level, not EM-specific.
E .False. Metrics exist in the DB, not just EMCC.

NEW QUESTION # 93
You want to apply the principle of least privilege in all your live databases. One of your requirements is to revoke unnecessary privileges from all users who have them using Privilege Analysis. Which two types of analyses can be done using the DBMS_PRIVILEGE_CAPTURE package?

A. Analysis of privileges that a user has on other schemas' objects.
B. Analysis of privileges granted directly to a role that are then used by a user who has been granted that role.
C. Analysis of all privileges used by the SYS user.
D. Analysis of privileges that a user has on their own schema objects.
E. Analysis of privileges granted indirectly to a role that are then used by a user who has been granted that role.

Answer: B,E

Explanation:
A .False. Limited to captured privileges, not all schema objects.
B .False. SYS is excluded from capture.
C .True. Captures indirect role privileges used.
D .True. Captures direct role privileges used.
E .False. Focus is on roles, not self-owned objects broadly.

NEW QUESTION # 94
Which three statements are true about Oracle Managed Files (OMF)?

A. If DB_RECOVERY_FILE_DEST is specified, at least two different locations must be specified for DB_CREATE_ONLINE_LOG_DEST_n.
B. If DB_CREATE_FILE_DEST is specified but DB_CREATE_ONLINE_LOG_DEST_n is not, new redo logs and control files are stored in DB_CREATE_FILE_DEST by default.
C. If DB_CREATE_ONLINE_LOG_DEST_1 is specified but DB_CREATE_FILE_DEST is not, new data files and temp files are stored in DB_CREATE_ONLINE_LOG_DEST_1 by default.
D. If only DB_CREATE_FILE_DEST is specified, only data files and temp files are Oracle managed.
E. If DB_RECOVERY_FILE_DEST is specified but DB_CREATE_ONLINE_LOG_DEST_n is not, the redo logs and control files are placed in DB_RECOVERY_FILE_DEST by default.
F. If only DB_CREATE_ONLINE_LOG_DEST_1 is specified, only redo logs and control files are Oracle Managed.

Answer: B,C,E

Explanation:
A .True. Without DB_CREATE_ONLINE_LOG_DEST_n, redo logs and control files default to DB_RECOVERY_FILE_DEST.
B .False. If only DB_CREATE_FILE_DEST is set, redo logs and control files also use it unless overridden.
C .True. DB_CREATE_ONLINE_LOG_DEST_1 becomes the default for data files and temp files if DB_CREATE_FILE_DEST is unset.
D .True. DB_CREATE_FILE_DEST serves as the default for all file types if no log-specific parameter is set.
E .False. Data files and temp files would also use DB_CREATE_ONLINE_LOG_DEST_1 if no other parameter is specified.
F .False. No such requirement exists; DB_RECOVERY_FILE_DEST operates independently.

NEW QUESTION # 95
Which statement is true about database links?

A. A public database link can be used by a user connected to the local database instance to connect to any schema in the remote database instance.
B. A public database link can be created only by SYS.
C. A database link can be created only between two Oracle databases.
D. Private database link creation requires the same user to exist in both the local and the remote databases.
E. A database link created in a database allows a connection from that database's instance to the target database's instance, but not vice versa.

Answer: E

Explanation:
Database links enable cross-database queries in Oracle. Let's analyze each option with extensive detail:
A . A public database link can be created only by SYS.
False. Any user with the CREATE PUBLIC DATABASE LINK privilege (not just SYS) can create a public link (e.g., CREATE PUBLIC DATABASE LINK remote_db CONNECT TO scott IDENTIFIED BY tiger USING 'orcl'). While SYS typically has this privilege, it's not exclusive to SYS.
Mechanics:Privilege is granted via GRANT CREATE PUBLIC DATABASE LINK TO user;. Public links are accessible to all users in the local DB.
Why Incorrect:Overly restrictive; Oracle's security model allows delegation.
B . A database link can be created only between two Oracle databases.
False. Database links can connect to non-Oracle databases using Oracle Heterogeneous Services or gateways (e.g., ODBC or JDBC drivers), such as linking to SQL Server. Example: CREATE DATABASE LINK mssql_link USING 'hsodbc';.
Mechanics:Requires configuration of hs_ parameters in init.ora and a gateway listener.
Historical Note:Heterogeneous links were introduced in 8i, expanded in 23ai for cloud integration.
C . A database link created in a database allows a connection from that database's instance to the target database's instance, but not vice versa.
True. A database link is unidirectional; it enables queries from the local instance to the remote instance (e.g., SELECT * FROM emp@remote_db), but the remote instance can't use it to query back unless a separate link is created there.
Mechanics:Stored in DBA_DB_LINKS, the link defines a one-way connection via a TNS alias or connect string.
Practical Use:Ensures controlled access; bidirectional access requires explicit configuration.
Edge Case:Loops are prevented unless explicitly designed with mutual links.
D . A public database link can be used by a user connected to the local database instance to connect to any schema in the remote database instance.
False. Public links allow all local users to use them, but access to remote schemas depends on the link's credentials (e.g., CONNECT TO scott) and the user's remote privileges. "Any schema" overstates it; access is limited to what the link's user can see.
Why Incorrect:Misrepresents privilege scope; remote schema access isn't universal.
E . Private database link creation requires the same user to exist in both the local and the remote databases.
False. A private link (e.g., CREATE DATABASE LINK my_linkCONNECT TO scott IDENTIFIED BY tiger USING 'orcl') requires the remote user (scott) to exist, but the local creator (e.g., HR) need not match. The link is owned locally and authenticated remotely.
Mechanics:Only the CREATE DATABASE LINK privilege is needed locally.
