최신 Oracle Cloud 1z0-1093-25 무료샘플문제 (Q83-Q88):

질문 # 83
Which Oracle Cloud Infrastructure (OCI) service is PRIMARILY used to store backups created from a BaseDB database?

A. OCI File Storage
B. OCI Data Transfer Service
C. OCI Archive Storage
D. OCI Object Storage
E. OCI Block Volume

정답：D

설명：
C: OCI Object Storage:
* The primary storage service for database backups within OCI.
* Offers high durability, availability, and scalability.
* Integrated with Oracle's automated backup solutions for BaseDB.
* Suitable for both short-term and long-term storage of database backups.
Why the other options are incorrect:
* A. OCI Block Volume:Used for primary database storage, not long-term backups.
* B. OCI File Storage:Typically used for file system-based workloads, not for database backups.
* D. OCI Archive Storage:Suitable for long-term archival but not the primary backup destination.
* E. OCI Data Transfer Service:Used for bulk data migration into OCI, not for backup storage.

질문 # 84
During the provisioning of a Base Database Service (BaseDB) virtual machine (VM), what is the significance of the "Compute Shape" selection?

A. It specifies the pre-installed database software version.
B. It defines the CPU, memory, and network bandwidth allocated to the VM.
C. It determines the maximum number of databases that can be created on the VM.
D. It dictates the availability domain in which the VM will be created.

정답：B

설명：
C: Defines CPU, memory, and network bandwidth:
* TheCompute Shapespecifies the resources allocated to the VM.
* Shapes vary in the number ofOCPUs, amount ofRAM, andnetwork performance.
* Selecting an appropriate shape ensures the database has enough computational power and memory to meet workload demands.
Why the other options are incorrect:
* A. Number of databases:Limited by storage and resource capacity, not the shape itself.
* B. Availability domain:Chosen separately during provisioning.
* D. Pre-installed software version:The shape does not determine the database version.

질문 # 85
When using a NoSQL Database Cloud Service SDK, what is the purpose of handling exceptions or errors returned by the SDK?

A. To provide detailed performance metrics to the database administrators.
B. To automatically recover from hardware failures in the cloud.
C. To ensure data consistency by retrying failed operations.
D. To implement custom logic for handling specific error conditions, such as record not found or insufficient capacity.

정답：D

설명：
Exception Handling in SDKs:
When developing applications using theOracle NoSQL Database Cloud Service SDK, it is essential to implementerror handling logic. This typically includes managing cases like:
* Record Not Found:Handling situations where a queried record does not exist.
* Insufficient Capacity:Managing requests when throughput limits are exceeded.
* Network Failures:Retrying operations or providing fallback mechanisms.The goal is to buildrobust and resilient applicationsthat gracefully handle unexpected conditions.
Why the other options are incorrect:
* A:Cloud infrastructure handles hardware recovery, not the SDK.
* B:While retrying may ensure consistency, it is the developer's responsibility to implement it.
* C:Performance metrics are gathered via monitoring tools, not exception handling.

질문 # 86
Which two actions can be performed using the Automatic Database Diagnostic Monitor (ADDM) within Database Management to diagnose cloud database performance?

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

정답：A,C

설명：
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.

질문 # 87
What role does the Exadata Storage Server Software play within the Exadata Database Service architecture?

A. It provides the operating system and management software for the database servers.
B. It manages the virtual machines hosting the database instances.
C. It provides intelligent storage capabilities, including data filtering, compression, and encryption.
D. It acts as a load balancer distributing connections across the database instances.

정답：C

설명：
C: Intelligent Storage Capabilities:
* The Exadata Storage Server Software enhances data processing at the storage layer.
* Key features include:
* Smart Scan:Offloads SQL processing to storage.
* Compression:Reduces data size and improves I/O efficiency.
* Encryption:Protects data at rest.
* This software significantly boosts database performance by reducing data transfer to the compute nodes.
Why the other options are incorrect:
* A. VM management:Handled by OCI infrastructure.
* B. OS and management software:Not related to Exadata Storage Server Software.
* D. Load balancing:Handled by Oracle RAC or OCI load balancers.
