Oracle Cloud Database Services 2025 Professional Sample Questions (Q33-Q38):

NEW QUESTION # 33
Which two are valid mechanisms for accessing OS-level metrics on a Base Database Service Virtual Machine?

A. Access OS metrics using the OCI Metrics Explorer within the OCI Console leveraging the Oracle Cloud Agent.
B. All OS metrics are automatically pushed to the Cloud Exadata Service Dashboard, and are not available outside of this service.
C. The only way to access OS-level metrics is through a custom monitoring agent installed directly on the VM.
D. Access OS metrics programmatically via the OCI Monitoring APIs, which allow retrieval of metrics collected by the Oracle Cloud Agent.
E. Utilize the vmcli utility, which allows access to OS-level metrics specific to the DB System.

Answer: A,D

Explanation:
B: Access OS metrics using the OCI Metrics Explorer within the OCI Console leveraging the Oracle Cloud Agent.
* OCI Metrics Explorer is part of the OCI Monitoring service.
* The Oracle Cloud Agent collects OS-level metrics and makes them available through the OCI Console.
* Users can view metrics like CPU usage, memory utilization, and disk I/O.
E: Access OS metrics programmatically via the OCI Monitoring APIs:
* The Oracle Cloud Agent collects OS metrics and exposes them via OCI Monitoring APIs.
* This approach allows for automated data retrieval and integration with external monitoring tools.
Why the other options are incorrect:
* A. vmcli utility:This is not a standard tool for accessing OS-level metrics on Base Database Service VMs.
* C. Custom monitoring agent:While possible, it is not the primary or only method. Oracle Cloud Agent is the default tool.
* D. Automatically pushed to the Cloud Exadata Service Dashboard:This statement is incorrect as OS metrics are available through OCI Monitoring.

NEW QUESTION # 34
When migrating to MySQL HeatWave on Oracle Cloud Infrastructure (OCI), what is the recommended method for securely transferring large database backups?

A. Use of Data Pump with a database link.
B. Shipping physical hard drives containing the backup files to the OCI data center.
C. Transferring the backup files directly over the public internet using FTP.
D. Creating a secure VPN connection and transferring the backup files using scp.
E. Using the Oracle Cloud Infrastructure Data Transfer Service with physical storage appliances.

Answer: E

Explanation:
Secure Transfer with OCI Data Transfer Service:
TheOCI Data Transfer Serviceis designed to securely transfer large datasets, including database backups, to the cloud. It involves:
* Using physical storage appliancesto copy data locally and then shipping these devices to OCI data centers.
* Data isencrypted and securely transported, minimizing the risks associated with online transfers.
* This method is cost-effective and practical forterabytes or petabytes of data, avoiding bandwidth limitations and reducing transfer time.
Why the other options are incorrect:
* A:FTP over the public internet is insecure and slow.
* B:Physical hard drives without encryption and secure handling increase data breach risks.
* D:SCP over VPN is secure but impractical for extremely large datasets.
* E:Data Pump is useful for database-to-database transfers, not large file migrations.

NEW QUESTION # 35
When provisioning a Base Database Service (BaseDB) virtual machine (VM) instance in Oracle Cloud Infrastructure (OCI), which of the following actions MUST be performed before launching the DB system?

A. Configuring the Data Guard association between the VM and a standby database.
B. Configuring Oracle GoldenGate replication.
C. Creating a backup policy for the database being provisioned.
D. Creating a Virtual Cloud Network (VCN) with appropriate subnets and security rules.

Answer: D

Explanation:
VCN Requirement:
AVirtual Cloud Network (VCN)is essential for creating a BaseDB VM instance because itprovidesnetwork connectivityandIP addressing. Subnets and security rules define the access policies and network segmentation.
Without a VCN, the VM instance cannot communicate with other resources or external networks.
Why the other options are incorrect:
* A:Data Guard can be configured after provisioning.
* B:Backup policies are important but can be set up later.
* D:Oracle GoldenGate replication is optional and not required at the time of provisioning.

NEW QUESTION # 36
Oracle NoSQL Database Cloud Service supports operations on data based on keys. Which of the following best describes how data is primarily accessed and retrieved within this model?

A. Data is accessed using structured query language (SQL) with joins and complex filtering conditions.
B. Data is retrieved by traversing relationships between interconnected nodes in a graph structure.
C. Data is primarily accessed using the unique key associated with the desired data item.
D. Data is accessed through a predefined schema that dictates how data is organized and queried.
E. Data is searched based on the content of the values using full-text indexing and complex search queries.

Answer: C

Explanation:
C: Accessing data using the unique key:
* Oracle NoSQL Database Cloud Service follows akey-value data model.
* Data is accessed directly using aunique key, which is highly efficient for lookups.
* The value associated with the key can be simple or complex (e.g., JSON objects).
* Provides fast read and write operations.
Why the other options are incorrect:
* A. SQL with joins:Typical of relational databases, not NoSQL.
* B. Graph traversal:Relevant to graph databases, not key-value stores.
* D. Full-text indexing:Not the primary access method in key-value databases.
* E. Predefined schema:NoSQL databases generally supportschema-lessdata storage.

NEW QUESTION # 37
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 create the initial database instance and its associated files.
B. To select the character set for the operating system.
C. To determine the operating system user account used for database administration.
D. To define the hostname for the database server.

Answer: A

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.
