Oracle Cloud Database Services 2025 Professional 認定 1z0-1093-25 試験問題 (Q33-Q38):

質問 # 33
Which two statements accurately describe the relationship between Database Management and metrics collected in OCI Monitoring service?

正解：A、B

解説：
B:Database Management directly queries the database to gather performance data, such as SQL performance and active session history. It also integrates with OCI Monitoring for infrastructure-level metrics like CPU, memory, and storage utilization.
C:Database Management can function independently of OCI Monitoring since it has its own data collection mechanisms.
Why the other options are incorrect:
* A:Database Management does not rely solely on OCI Monitoring.
* D:It does not require custom metrics from the user.


質問 # 34
Which two actions must you undertake when configuring the networking to provide network connectivity for a MySQL HeatWave DB System instance?

正解：A、C

解説：
A: Service Gateway for Oracle Services:
* Ensures the HeatWave DB System can accessOracle Serviceslike Object Storage without using the public internet.
* Essential for tasks such aspatching and backups.
C: Ingress security rules:
* Allows necessary traffic to reach the HeatWave DB System.
* Typically, rules will permitMySQL port (3306)and anyapplication-specific ports.
* Configured usingVCN security lists or NSGs.
Why the other options are incorrect:
* B. Public subnet deployment:Exposes the database to the internet, which is a security risk.
* D. Dynamic routing gateway:Not mandatory unless inter-VCN connectivity is specifically required.
* E. Blocking egress entirely:Restricting all outbound traffic can prevent necessary updates and communication with Oracle services.


質問 # 35
Oracle NoSQL Database Cloud Service utilizes a key-value data model. Which of the following statements accurately describes the fundamental structure of data within this model?

正解：B

解説：
C: Each data item is uniquely identified by a key, and the associated value can be any data type or structure.
Key-Value Data Model:
* The key-value model is fundamentally based on a simple association between a unique key and its corresponding value.
* The value can be a simple data type (string, number) or a complex structure (like JSON).
* Oracle NoSQL Database Cloud Service uses this model to ensure efficient, scalable data access.
Why the other options are incorrect:
* A. Organized into tables with schemas:This represents a relational database model.
* B. Stored as JSON documents:Although NoSQL can store JSON, the fundamental model is still key- value.
* D. Relationships defined through foreign keys and joins:This is typical of relational databases.
* E. Graph format with nodes and edges:Represents a graph database model, not key-value.


質問 # 36
Which statement accurately describes the function of the HeatWave service in relation to a standard MySQL database?

正解：E

解説：
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.


質問 # 37
