Just as an old saying goes, it is better to gain a skill than to be rich. Contemporarily, competence far outweighs family backgrounds and academic degrees. One of the significant factors to judge whether one is competent or not is his or her certificates. 1z0-1093-25 real test) Generally speaking, certificates function as the fundamental requirement when a company needs to increase manpower in its start-up stage. In this respect, our 1z0-1093-25 practice materials can satisfy your demands if you are now in preparation for a certificate.

Oracle Cloud Database Services 2025 Professional Sample Questions (Q55-Q60):

NEW QUESTION # 55
You are managing an Exadata Database Service (ExaDB) and need to perform a full backup of the database to Oracle Cloud Infrastructure Object Storage using the bkup_api utility. The backup must include all datafiles and control files. Which bkup_api command will achieve this?

A. bkup_api bkup_start --datafiles --controlfile --dbname=dbname
B. bkup_api bkup_start --full --dbname=dbname
C. bkup_api bkup_start --dbname=dbname
D. bkup_api bkup_start --all --dbname=dbname

Answer: B

Explanation:
Full Backup with bkup_api:
The --full flag in thebkup_api commandensures that the backup includesall datafiles and control files. This command is essential for creating acomplete, consistent backupsuitable for recovery purposes.
* The backup is stored inOCI Object Storage, leveraging cloud scalability and redundancy.
* The --dbname parameter specifies which database to back up.
Why the other options are incorrect:
* A:This command may initiate a default backup, not a full one.
* B:Specifying files individually is less efficient than using --full.
* D:The --all option does not necessarily imply a full backup.

NEW QUESTION # 56
When enabling Database Management Service for a cloud database, which of the following is typically NOT a configurable parameter specific to the Database Management Service itself?

A. The frequency at which performance metrics are collected.
B. The maximum amount of storage space allocated for collected metrics.
C. The database version.
D. The specific metrics that are collected from the database.

Answer: C

Explanation:
D: The database version:
* Thedatabase versionis not configurable through the Database Management Service.
* The version is determined during the database instance provisioning and is independent of the management service.
* The management service can monitor and manage databases of various versions, but it does not control or alter the version itself.
Why the other options are configurable:
* A. Frequency of metric collection:Can be adjusted to balance performance and data granularity.
* B. Specific metrics collected:Can be customized based on monitoring requirements.
* C. Storage space for metrics:Some configurations allow defining the retention and storage capacity for collected data.

NEW QUESTION # 57
Which two of the following statements are true regarding security considerations for managingExadata Cloud Infrastructure and VM Clusters?

A. Customers have full access to the Exadata Infrastructure's hypervisor and can implement custom security policies.
B. Oracle manages all security aspects of the Exadata Infrastructure, relieving customers of any security responsibilities.
C. Customers are responsible for configuring and maintaining the security of the operating system and database software within the VM Clusters.
D. Customers are responsible for configuring host-based firewalls on the Exadata Infrastructure to protect against unauthorized access.
E. Network Security Groups (NSGs) can be used to control network traffic to and from VM Clusters, enhancing security.

Answer: C,E

Explanation:
B: Network Security Groups (NSGs) for traffic control:
* NSGs allow customers to defineingress and egress rulesto control network traffic.
* Enhances security by restricting access to only authorized IP ranges and protocols.
* Applied at theVM Clusterlevel to manage connectivity efficiently.
E: Responsibility for OS and database security:
* While Oracle manages the infrastructure layer, customers are responsible for securing theoperating system and databasewithin the VM Clusters.
* This includes applying security patches, configuring firewalls, and implementing user access controls.
Why the other options are incorrect:
* A. Host-based firewalls on Exadata Infrastructure:Oracle, not the customer, configures the infrastructure-level security.
* C. Oracle managing all security:Incorrect, as customers manage VM-level security.
* D. Access to hypervisor:Customers do not have hypervisor-level access for security configuration.

NEW QUESTION # 58
Which two actions can be performed using the Automatic Database Diagnostic Monitor (ADDM) within Database Management to diagnose cloud database performance?

A. Automatically create indexes to improve query performance.
B. Automatically apply all ADDM recommendations to the database.
C. Identify root causes of performance bottlenecks, such as excessive I/O or CPU contention.
D. Generate recommendations for SQL plan baselines.

Answer: C,D

Explanation:
A: Generate recommendations for SQL plan baselines:
* ADDM analyzes historical data andSQL execution plans, suggesting baseline adjustments to optimize performance.
* Recommendations may includeusing an existing baselineor creating a new one.
C: Identify performance bottlenecks:
* ADDM pinpoints issues related to:
* I/O contention
* CPU utilization
* Memory bottlenecks
* Locking issues
* Helps DBAs understand which database components are causing slowdowns.
Why the other options are incorrect:
* B. Automatically applying recommendations:ADDM only suggests actions; DBAs must manually review and implement them.
* D. Creating indexes:ADDM does not create indexes automatically; it may suggest them, but implementation requires DBA action.

NEW QUESTION # 59
Which statement BEST describes the primary architectural distinction between Exadata Database Service and a traditional Oracle Database deployed on virtual machines in the cloud?

A. Exadata Database Service utilizes only virtualized compute nodes, while traditional deployments use bare metal.
B. Exadata Database Service integrates specialized, high-performance storage servers and a high- bandwidth, low-latency RDMA over Converged Ethernet (RoCE) network, optimized for database workloads, which are not present in typical cloud VM deployments.
C. Exadata Database Service uses a completely different SQL parsing engine compared to a traditional Oracle Database.
D. Exadata Database Service exclusively supports Oracle RAC, while traditional cloud deployments can support both single-instance and RAC databases.

Answer: B

Explanation:
Exadata's Unique Architecture:
Exadata Database Service is engineered specifically for Oracle Database workloads. The architecture leverages specialized storage servers that performdata-intensive operations at the storage level(such as filtering and aggregation), reducing the amount of data sent to the compute nodes.
TheRoCE network(RDMA over Converged Ethernet) provides high-bandwidth, low-latency connectivity between compute and storage nodes, significantly enhancing I/O performance. This architecture is optimized for bothOLTP and OLAP workloads, making Exadata a superior choice for performance-critical applications.
Why the other options are incorrect:
* A:Exadata combines both virtualized and bare metal compute nodes.
* C:Both Exadata and traditional cloud deployments can support Oracle RAC, but Exadata is optimized for it.
* D:Exadata uses the same Oracle Database SQL parsing engine; the difference lies in the optimized hardware.
