Oracle Cloud Database Services 2025 Professional Sample Questions (Q24-Q29):

NEW QUESTION # 24
You are tasked with checking the status of the Exadata Database Service (ExaDB) components using the dcli utility. You need to gather information about the health and status of the database servers and storage cells across the ExaDB infrastructure. Which dcli command, combined with appropriate commands run across the nodes, will provide the most comprehensive overview?

  • A. dcli -g dbnodes "list dbnodes"
  • B. dcli -g cell_group "list cell attributes name, status, metriccurrent"
  • C. dcli -g cell_group "list cell attributes name, status" combined with dcli -g dbnodes "srvctl status database -d dbname"
  • D. dcli -g all "list status"

Answer: C

Explanation:
A: dcli -g cell_group "list cell attributes name, status" combined with dcli -g dbnodes "srvctl status database -d dbname" dcli Utility:
* dcli(Distributed Command Line Interface) allows you to run commands on multiple nodes simultaneously.
* cell_group: A group configuration file listing all storage cells.
* dbnodes: A group configuration file listing all database nodes.
Commands Explanation:
* dcli -g cell_group "list cell attributes name, status":
* Retrieves the name and current status of each storage cell.
* dcli -g dbnodes "srvctl status database -d dbname":
* Checks the status of the database instances on the compute nodes.
* Combining these commands provides a complete picture of both storage and compute components.
Why the other options are incorrect:
* B. Including metriccurrent:Produces excessive output, not suitable for a quick health check.
* C. Listing dbnodes only:Insufficient as it lacks storage cell status.
* D. dcli -g all "list status":Invalid syntax and lacks specificity.


NEW QUESTION # 25
In a column-family NoSQL database, what is the purpose of a "super column"?

  • A. To define the primary key for the entire database.
  • B. To store large binary objects (BLOBs).
  • C. To represent a single value associated with a row key.
  • D. To group related columns together, providing a level of hierarchy within the column family.

Answer: D

Explanation:
Super Columns in Column-Family Databases:
Asuper columnis a higher-level construct used incolumn-family NoSQL databases(like Apache Cassandra).
It groups related columns together under a single name, forming atwo-level hierarchywithin a column family.
* This structure is useful when storing data that naturally fits anested or hierarchical format.
* For example, a user profile might contain super columns like "Address" (with sub-columns like
"Street", "City", "ZIP") and "Contacts" (with sub-columns like "Phone", "Email").
Why the other options are incorrect:
* A:A regular column represents a single value associated with a row key.
* C:Primary keys are defined at the row level, not using super columns.
* D:While BLOBs can be stored, the primary role of a super column is togroup related columns, not store binary data.


NEW QUESTION # 26
When cloning a BaseDB database for development and testing, which of the following considerations is MOST critical to ensure compliance with data privacy regulations?

  • A. Masking or anonymizing sensitive data in the cloned database.
  • B. Ensuring the compute shape of the cloned database is identical to the production database.
  • C. Using the same database version as the production database.
  • D. Maintaining the same network security group (NSG) rules as the production database.
  • E. Scheduling the cloning operation during off-peak hours.

Answer: A

Explanation:
B: Masking or anonymizing sensitive data:
* Data privacy regulations (likeGDPR,HIPAA) mandate thatpersonally identifiable information (PII) is protected, even in non-production environments.
* Cloning a database without masking sensitive data could expose confidential information to unauthorized users.
* Techniques include:
* Data masking:Replacing real data with realistic, but non-sensitive values.
* Data anonymization:Irreversibly removing personally identifiable information.
Why the other options are incorrect:
* A. Matching compute shape:Relevant to performance, not privacy.
* C. Using the same database version:Important for compatibility, but not related to data privacy.
* D. Same NSG rules:Important for network security, but does not directly address data exposure.
* E. Off-peak scheduling:Minimizes disruption but does not address data protection.


NEW QUESTION # 27
Which statement accurately reflects the impact of applying an Oracle-provided patch to the operating system on an Exadata Database Service instance using the Oracle Cloud Infrastructure (OCI) console?

  • A. The OCI console-initiated patch process only patches the storage servers; database nodes require manual OS patching.
  • B. The OCI console-initiated patch process automatically updates both the database software and the underlying operating system on all compute and storage nodes concurrently.
  • C. The OCI console-initiated patch process updates the database software and the OS, allowing for a rolling update strategy on the database nodes, minimizing downtime. Storage nodes are updated separately.
  • D. The OCI console-initiated patch process only updates the database software, leaving the underlying OS untouched.

Answer: C

Explanation:
OCI Patching Process:
The Oracle Cloud Infrastructure console simplifies the patching process by integrating bothdatabase software and OS patching. Therolling update strategyensures that one node at a time is patched, reducing the downtime associated with updating the entire cluster. The storage nodes are updated in a separate process to ensure data integrity and availability.
Why the other options are incorrect:
* A:The OCI console updates both the OS and database software.
* B:Updates are performed in a rolling fashion, not concurrently.
* D:The OCI console handles OS patching for both compute and storage nodes.


NEW QUESTION # 28
Which of the following is a TRUE statement regarding the storage options typically available when launching an Oracle Cloud Infrastructure (OCI) Base Database Service (BaseDB) virtual machine (VM)?

  • A. File Storage is mandatory for database backups.
  • B. Block Volumes provide the primary storage and are directly attached to the VM.
  • C. Object Storage is the default storage option for database datafiles.
  • D. Local NVMe storage is always the default for BaseDB.

Answer: B

Explanation:
A: Block Volumes provide the primary storage and are directly attached to the VM.
Block Volumes:
* These are persistent, durable block storage volumes that are attached to the VM instance.
* Used to store database datafiles, redo logs, and other database-related files.
* Standard and most common way to provision storage for BaseDB VMs.
Why the other options are incorrect:
* B. Object Storage as the default for database datafiles:Object Storage is used for backups and unstructured data, not the primary database files.
* C. Local NVMe as the default:Local NVMe provides high performance but is not always the default.
Block Volumes are standard.
* D. File Storage is mandatory for backups:Not mandatory. Block Volumes or Object Storage can also be used.
