Oracle Cloud Database Services 2025 Professional 1z0-1093-25 Prüfungsfragen mit Lösungen (Q58-Q63):58. Frage
In comparing NoSQL databases with relational databases, what constitutes a fundamental difference in their approach to data relationships?
  • A. Relational databases primarily rely on foreign keys to define relationships, while NoSQL databases often embed related data within a single document or use application-level links.
  • B. NoSQL databases universally lack the ability to represent relationships between data elements.
  • C. NoSQL databases exclusively use foreign keys to establish relationships, similar to relational database models.
  • D. Relational databases offer no mechanism for defining relationships between different data sets.
Antwort: A
Begründung:
B: Relational vs. NoSQL data relationships:
* Relational Databases:Useforeign keysto establish relationships between tables, maintaining referential integrity.
* NoSQL Databases:Typically do not enforce relationships through foreign keys. Instead, they:
* Embed related datawithin a single document (common in document stores like MongoDB).
* Useapplication-level joinsto link related data (common in key-value or column-family stores).
* Graph databases (a type of NoSQL) useedgesto explicitly represent relationships between nodes.
* This difference highlights theflexibility vs. consistencytrade-off between NoSQL and relational databases.
Why the other options are incorrect:
* A. NoSQL databases lack relationships:Incorrect; they handle relationships differently.
* C. NoSQL using foreign keys exclusively:NoSQL databases generally do not enforce such relationships.
* D. Relational databases lack relationship mechanisms:Incorrect as relational databases are designed around relationships.

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

60. Frage
When using a NoSQL Database Cloud Service SDK, what is the purpose of handling exceptions or errors returned by the SDK?
  • A. To implement custom logic for handling specific error conditions, such as record not found or insufficient capacity.
  • B. To ensure data consistency by retrying failed operations.
  • C. To provide detailed performance metrics to the database administrators.
  • D. To automatically recover from hardware failures in the cloud.
Antwort: A
Begründung:
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.
* Cerformance metrics are gathered via monitoring tools, not exception handling.

61. Frage
When considering autoscaling for provisioned throughput in NoSQL Database Cloud Service, which metric is LEAST relevant for determining when to scale up the capacity units?
  • A. Latency of read and write operations.
  • B. Number of rejected read requests due to insufficient RCUs.
  • C. CPU utilization of the compute instances hosting the database.
  • D. Number of rejected write requests due to insufficient WCUs.
Antwort: C
Begründung:
A: CPU utilization of the compute instances hosting the database:
* Autoscaling in NoSQL Database Cloud Service primarily focuses onRCUs (Read Capacity Units)and WCUs (Write Capacity Units).
* The objective is to dynamically adjust capacity based onquery workload, not onCPU utilization.
* Even if CPU usage is high, it might not necessarily indicate that the capacity units are inadequate.
Why the other options are more relevant:
* B. Rejected read requests (RCUs)irect indicator that read capacity is insufficient, requiring scaling.
* C. Rejected write requests (WCUs):Indicates that the write throughput is inadequate, necessitating scaling.
* D. Latency of read and write operations:Increased latency often points to under-provisioned throughput.

62. Frage
Within an IAM policy for Oracle NoSQL Database Cloud Service, what is the purpose of the "resource" element when defining table access permissions?
  • A. To determine the geographical region where the NoSQL database is located.
  • B. To specify the IAM group that the policy applies to.
  • C. To define the specific NoSQL table or tables to which the policy's permissions apply.
  • D. To set the expiration date for the IAM policy.
Antwort: C
Begründung:
B: Define specific NoSQL table permissions:
* The"resource"element specifies which Oracle NoSQL tables the IAM policy will apply to.
* It allows fine-grained access control by linking specific tables to permission statements.
* This ensures that only authorized users or groups can perform operations on specified tables.
Example IAM Policy Syntax:
{
"action": "nosql:table:read",
"resource": "ocid1.nosqltable.oc1..exampleuniqueID",
"effect": "allow"
}
Why the other options are incorrect:
* A. Specify IAM group:Groups are defined in the"subject"element, not the "resource" element.
* C. Geographical region:The region is usually part of theOCID(Oracle Cloud Identifier), not directly specified in the resource element.
* D. Set expiration date:Expiry is not defined within the "resource" element.
