Ace Your 1z0-931-25 Oracle Cloud Infrastructure Exam

Full Detailed In-Depth Explanation:

A:True. Data Insights works with tables and business models in ADW.

B:False. Exclusive to Autonomous Database, not on-premises.

C:True. Search history is retrievable.

D:False. Included in ADW, not separately priced.

Full Detailed In-Depth Explanation:

REST APIs use HTTP verbs:

A:True. POST creates new resources, such as an Autonomous Database instance.

B:False. GET retrieves data, not creates.

C:False. PUT updates existing resources.

D:False. INSERT is not a REST verb; it’s SQL-specific.

Oracle Spatial Studio is a self-service tool for working with spatial data in Autonomous Database. The three correct functions are:

Map visualization (A):Spatial Studio provides robust capabilities to visualize spatial data on interactive maps, enabling users to explore geographic patterns and relationships visually.

Spatial analysis (C):It offers tools for performing spatial operations like proximityanalysis, spatial joins, and buffering, which are essential for deriving insights from geographic data.

Spatial data editing (E):Users can edit spatial data, such as modifying geometries or updating attributes, directly within Spatial Studio, making it a powerful tool for data management.

The incorrect options are:

Custom SQL queries (B):While Spatial Studio supports spatial operations, it is primarily a graphical tool and does not focus on executing custom SQL queries. Such functionality is more aligned with tools like SQL Developer.

Geocoding (D):Geocoding (converting addresses to coordinates) is not a core feature of Spatial Studio. It focuses on visualization, analysis, and editing rather than address-to-coordinate conversion, which is typically handled by separate Oracle services or tools.

These functions align with Spatial Studio’s purpose of simplifying spatial data management and analysis.

Oracle Cloud Infrastructure (OCI) is designed with a hierarchical structure to ensure high availability and fault tolerance:

Correct Answer (B): “An OCI region is a localized geographic area, and an availability domain is one or more data centers located within a region” accurately describes OCI’s architecture. A region is a standalone geographic area (e.g., US East), and availability domains (ADs) are isolated data centers within that region, enhancing resilience.

Correct Answer (D): “Because availability domains do not share infrastructure such as power or cooling, or the internal availability domain network, a failure at one availability domain within a region is unlikely to impact the availability of the others within the same region” reflects OCI’s design for fault isolation. ADs are physically separate, minimizing the risk of cascading failures.

Incorrect Options:

A: Regions are independent, not dependent, and there’s no 5,000-kilometer restriction; they are globally distributed for latency and redundancy purposes.
