Oracle Cloud Database Services 2025 Professional Sample Questions (Q96-Q101):

NEW QUESTION # 96
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 create the initial database instance and its associated files.
D. To select the character set for the operating system.

Answer: C

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 # 97
When provisioning an Oracle Cloud Infrastructure (OCI) Base Database Service (BaseDB) on a virtual machine (VM), what is a primary factor that distinguishes it from using a Bare Metal database service?

A. The ability to choose your own hypervisor for virtualization.
B. The underlying hardware is dedicated solely to your instance.
C. The database software binaries are always pre-installed.
D. The ability to create multiple database homes on a single server.

Answer: B

Explanation:
Primary Distinction:
The primary difference betweenBaseDB on a VMandBare Metalis how the underlying hardware is allocated:
* BaseDB on VM:The infrastructure issharedamong multiple tenants, using virtualization to isolate instances.
* Bare Metal Database Service:The server'sphysical hardware is dedicatedexclusively to a single tenant, offeringmaximum performance and isolation.
* This exclusive access to hardware in Bare Metal allows forbetter performanceand control compared to VM-based instances.
Why the other options are incorrect:
* A:Binaries are not always pre-installed in both cases; it depends on the configuration.
* B:Oracle handles hypervisor configuration, not the user.
* D:Both VM and Bare Metal allow multiple database homes if configured properly.

NEW QUESTION # 98
Within the context of Exadata Database Service, what does scaling out primarily refer to?

A. Increasing the CPU core count of a single database server VM.
B. Expanding the amount of RAM available to a single database instance.
C. Upgrading the version of the Oracle Database software.
D. Adding additional database server VMs and storage servers to the Exadata system.

Answer: D

Explanation:
Scaling Out:
Scaling out in Exadata means increasing thenumber of database server VMs and storage serversto handle a larger workload. This is achieved byadding more compute nodesand storage cells, allowing the system to distribute database processingacross multiple nodes.
This horizontal scalability is ideal for environments with fluctuating workloads or growing data volumes. It improvesquery performance and fault tolerancesince data and workload are distributed across more hardware resources.
Why the other options are incorrect:
* A:Increasing CPU cores within a single VM is consideredscaling up.
* C:Upgrading the database software version is unrelated to scaling.
* D:Increasing RAM is also a form of scaling up, not scaling out.

NEW QUESTION # 99
Which two of the following options are valid statements regarding the management of the operating system on a Base Database Service Virtual Machine DB System?

A. Customers are responsible for the initial OS installation, but then patching is controlled entirely by Oracle.
B. Customers are responsible for the security and maintenance of the operating system, including applying necessary patches and updates.
C. Customers have full root access to the underlying operating system of the Virtual Machine DB System, allowing for customization and installation of custom software.
D. Oracle manages the underlying operating system patching and updates, ensuring the system remains secure and compliant.
E. Direct SSH access to the underlying VM is restricted, and all OS-level operations must be performed through the Web Console.

Answer: B,C

Explanation:
B: Full root access:
* Customers have root-level access to manage the OS, install custom software, and configure settings.
* This provides flexibility to meet specific application requirements.
D: Responsibility for OS security:
* With root access, customers must manage OS security, including updates and patches.
* Oracle provides tools to facilitate patching, but the responsibility lies with the customer.
Why the other options are incorrect:
* A. Restricted SSH access:SSH access is allowed for VM DB systems.
* C. Oracle-managed OS patching:Oracle does not automatically patch the OS; this is a customer responsibility.
* E. Initial OS installation by customers:The OS is pre-installed, but ongoing maintenance is customer- driven.

NEW QUESTION # 100
You are tasked with monitoring the I/O performance of an Exadata Database Service (ExaDB) using the exadcli utility. You need to retrieve detailed statistics on Smart Flash Cache usage, including read and write operations, at the storage cell level. Which exadcli command will provide the most comprehensive information?

A. exadcli list metriccurrent -cell -metricname "IOPS,MBPS"
B. exadcli list metriccurrent -cell -metricname "cell.*"
C. exadcli list metrichistory -cell -metricname "flashcache_read_iops,flashcache_write_iops"
D. exadcli list metricdetail -cell -metricname "flashcache.*"

Answer: D

Explanation:
Detailed Flash Cache Monitoring:
The commandexadcli list metricdetail -cell -metricname "flashcache.*"provides acomprehensive overviewof all metrics related toSmart Flash Cache. This includes bothread and write operations, hit ratios, and IOPS statistics.
* Themetricdetailoption retrieves in-depth data, crucial for performance troubleshooting.
* Theflashcache.*wildcard captures all relevant metrics associated with the Flash Cache subsystem.
Why the other options are incorrect:
* A:Limited to current IOPS and throughput, not specifically flash cache.
* C:Too broad, as it includes general cell metrics.
* D:Focuses only on historical read/write IOPS, not comprehensive.
