Oracle Cloud Database Services 2025 Professional Sample Questions (Q73-Q78):

NEW QUESTION # 73
Which BaseDB lifecycle management activity is MOST directly associated with ensuring the continued availability of a database instance during a planned maintenance window?

A. Applying a quarterly security patch.
B. Taking a full database backup using RMAN.
C. Using Oracle Data Guard for a switchover operation.
D. Performing an in-place upgrade of the database software.
E. Resizing the block volume storage.

Answer: C

Explanation:
C: Using Oracle Data Guard for a switchover operation:
* Aswitchoveris a planned role reversal between the primary and standby databases.
* Zero data loss:Since both databases are synchronized, it minimizes downtime.
* Ideal for planned maintenance:The primary database is switched to the standby, allowing maintenance on the original primary without downtime.
* Data Guard Switchover:
sql
CopyEdit
ALTER DATABASE SWITCHOVER TO standby_db;
Why the other options are incorrect:
* A. Full backup with RMAN:Backup does not ensure availability during maintenance.
* B. In-place upgrade:Typically involves downtime.
* D. Quarterly patch:Patching often requires database restarts, causing downtime.
* E. Resizing block volume:Does not maintain availability if the database requires restarting.

NEW QUESTION # 74
Which of the following components is responsible for automatically offloading suitable queries from MySQL to the HeatWave accelerator?

A. HeatWave AutoPilot
B. MySQL Query Optimizer
C. MySQL Router
D. MySQL Shell
E. Oracle Cloud Infrastructure (OCI) Load Balancer

Answer: B

Explanation:
A: MySQL Query Optimizer:
* TheMySQL Query Optimizerdetermines whether a query can benefit from HeatWave's in-memory, columnar processing.
* If a query is deemed suitable, it is automatically offloaded to the HeatWave cluster.
* This process significantly improves the execution speed of complex analytical queries.
Why the other options are incorrect:
* B. HeatWave AutoPilot:Manages workload optimization but does not directly offload queries.
* C. MySQL Router:Manages connection routing, not query offloading.
* D. MySQL Shell:Primarily used for administrative tasks, not query optimization.
* E. OCI Load Balancer:Manages network traffic distribution, unrelated to database query processing.

NEW QUESTION # 75
If the Database Management Service is failing to collect performance metrics from a cloud database, which is the LEAST likely cause?

A. The Database Management Service instance is located in a different region than the database.
B. Incorrect IAM policies preventing the service from accessing the database.
C. The database is temporarily offline.
D. The database user account used by the Management Agent has been locked.

Answer: A

Explanation:
Reasoning:
TheDatabase Management Servicecan collect performance metrics from databases across different regions within the same OCI tenancy. Therefore, the geographic location of the service relative to the database isnot a common issue.
More Likely Causes:
* A:IAM policies that do not grant sufficient permissions are a common issue.
* B:If the database is offline, no metrics can be collected.
* D:A locked database user account used by the Management Agent will prevent data collection.
Why C is incorrect:
The Database Management Service can be configured to collect metrics from databasesacross regions, as long as network access and permissions are properly configured.

NEW QUESTION # 76
During the provisioning of an Oracle Cloud Infrastructure (OCI) Base Database Service (BaseDB) virtual machine (VM), what is the PRIMARY purpose of specifying the database name (DB Name)?

A. To determine the operating system user account used for database administration.
B. To define the hostname for the database server.
C. To select the character set for the operating system.
D. To create the initial database instance and its associated files.

Answer: D

Explanation:
Database Name (DB Name):
When provisioning aBaseDB VM, thedatabase nameis used to create the initial instance. It specifies how the database will be identified and helps in creating associated system files, such ascontrol files, redo log files, and datafiles. This name is crucial fordatabase instance managementand connectivity within the OCI environment.
The DB name becomes part of theDB System resource identifierin OCI, which is used in automation and management tasks.
Why the other options are incorrect:
* A:The hostname is specified independently during network configuration.
* B:OS user accounts are configured separately.
* D:The character set is chosen during database configuration, not based on the DB name.

NEW QUESTION # 77
Which statement accurately describes the patching process for Oracle Grid Infrastructure (GI) and ASM components on a BaseDB VM system when using user-managed patching?

A. GI and ASM patching is fully automated by Oracle Cloud Infrastructure and requires no user intervention.
B. GI and ASM patching is integrated with the database patching process and is automatically handled when the database is patched.
C. Patching GI and ASM components is only required when the operating system of the VM is upgraded.
D. The DBA must manually download the GI and ASM patch bundles and apply them using the appropriate patching tools.

Answer: D

Explanation:
B: Manual patching for GI and ASM:
* In auser-managed environment, the DBA is responsible for downloading and applying patches for Grid Infrastructure (GI)andAutomatic Storage Management (ASM).
* These patches are distinct fromdatabase patchesand need to be applied using tools likeopatchorOracle Universal Installer (OUI).
* The process involves:
* Downloading the patch from Oracle Support.
* Staging the patch on the server.
* Applying the patch using the appropriate commands.
Why the other options are incorrect:
* A. Fully automated by OCI:OCI does not automatically patch GI and ASM in user-managed environments.
* C. Integrated with database patching:GI and ASM patching is handled separately.
* D. Required only during OS upgrade:Incorrect, as patching is required independently for security and stability.
