Oracle Cloud Database Services 2025 Professional Sample Questions (Q98-Q103):

NEW QUESTION # 98
Which two options correctly describe methods for accessing and managing the Exadata Infrastructure?

A. Exadata Infrastructure management is solely managed by Oracle and is not directly accessible to customers.
B. Management of the Exadata Infrastructure is primarily performed through the Oracle Cloud Infrastructure (OCI) console and APIs.
C. The dbcli utility, used for database administration on VM DB Systems, can also be used to manage the Exadata Infrastructure.
D. Direct SSH access to the Exadata Infrastructure compute nodes is permitted for customers with root privileges.
E. Customers have direct access to the Exadata storage cells, allowing them to modify storage configurations.

Answer: A,B

Explanation:
Managing Exadata Infrastructure:
* OCI Console and APIs (B):The primary method for managing Exadata Infrastructure is through the Oracle Cloud Infrastructure Consoleand associated APIs. This includes provisioning, scaling, patching, and monitoring the Exadata environment.
* Oracle-Managed Infrastructure (E):Exadata Infrastructure management is fully handled by Oracle, which means customers do not have direct access to the underlying hardware. This managed approach ensureshigh availability and security.
Why the other options are incorrect:
* A:Customers do not have root access to Exadata compute nodes to ensure security and system integrity.
* C:Thedbcli utilityis designed for VM DB Systems, not Exadata Infrastructure management.
* D:Exadata storage cells are managed by Oracle, and customers cannot directly modify storage configurations.

NEW QUESTION # 99
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. Local NVMe storage is always the default for BaseDB.
B. Object Storage is the default storage option for database datafiles.
C. File Storage is mandatory for database backups.
D. Block Volumes provide the primary storage and are directly attached to the VM.

Answer: D

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.

NEW QUESTION # 100
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 all "list status"
B. dcli -g cell_group "list cell attributes name, status" combined with dcli -g dbnodes "srvctl status database -d dbname"
C. dcli -g cell_group "list cell attributes name, status, metriccurrent"
D. dcli -g dbnodes "list dbnodes"

Answer: B

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 # 101
Which statement accurately describes the function of the HeatWave service in relation to a standard MySQL database?

A. HeatWave provides an in-memory, massively parallel query accelerator to MySQL, improving analytical query performance.
B. HeatWave is a standalone database system that replaces MySQL, offering enhanced security features.
C. HeatWave is a specialized version of MySQL designed solely for transactional workloads, optimized for high concurrency.
D. HeatWave is a clustering solution, where a single MySQL instance is split into multiple parts.
E. HeatWave acts as a caching layer in front of MySQL, speeding up access to frequently accessed data.

Answer: A

Explanation:
HeatWave as a Query Accelerator:
HeatWave enhances theMySQL Database Serviceby providing anin-memory, massively parallel query accelerator. It is specifically designed to speed upanalytical (OLAP) queries, making them run significantly faster compared to using MySQL alone.
* The system stores data in acolumnar formatand processes it in memory, utilizingdistributed, parallel processingto achieve high performance.
* Unlike traditional MySQL setups, HeatWave canexecute complex analytical workloadsefficiently.
Why the other options are incorrect:
* A:HeatWave is not a standalone database but an extension of MySQL.
* C:It is optimized foranalytical workloads, not transactional.
* D:It is more than just a caching layer; it actively processes queries.
* E:HeatWave clusters do not split MySQL instances but enhance query processing.

NEW QUESTION # 102
Which two are valid mechanisms for accessing OS-level metrics on a Base Database Service Virtual Machine?

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

Answer: B,E

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.
