QUESTION 29
What is the most important reason to upgrade and patch?

Security

Restructure the database

Fix bugs

Upgrading and patching the database is not important

The most important reason to upgrade and patch is “Security” (A). Patches address vulnerabilities, protecting against exploits and ensuring compliance, which outweighs “Fix bugs” (C) in priority. “Restructure the database” (B) is unrelated to patching, and “Upgrading and patching the database is not important” (D) is false. Oracle’s security guidelines prioritize patching for protection.

QUESTION 30
What set of NoSQL-style APIs can be used in Autonomous JSON Database?

OASD (Oracle Application Storage Definition)

SODA (Simple Oracle Document Access)

DOSA (Document Open Solution Access)

OSDA (Oracle Simple Document Access)

The “Autonomous JSON Database” supports NoSQL-style document access through “SODA” (Simple Oracle Document Access) APIs (B). SODA provides a simple, intuitive interface for developers to interact with JSON documents stored in the database using operations like insert, query, and update, without requiring SQL knowledge. Options A (“OASD”), C (“DOSA”), and D (“OSDA”) are not recognized API sets in Oracle’s documentation. SODA is explicitly documented as the standard NoSQL API for Autonomous JSON Database, aligning with Oracle’s converged database strategy to support multiple data models.

QUESTION 31
A customer wants to use Oracle Cloud Infrastructure (OCI) for storing application backups which can be stored for months, but retrieved immediately based on business needs. Which OCI storage service can be used to meet this requirement?

Object Storage (standard)

Archive Storage

File Storage

Block Volume

For storing application backups that need to be “stored for months, but retrieved immediately,” “Object Storage (standard)” (A) is the suitable OCI service. Standard Object Storage offers durable, scalable storage with immediate access, ideal for backups requiring quick retrieval. “Archive Storage” (B) is cheaper but has retrieval delays, unsuitable for immediate access. “File Storage” (C) is for shared file systems, and “Block Volume” (D) is for high-performance attached storage, both less suited for long-term backups. Oracle’s OCI Storage documentation confirms Standard Object Storage for this use case.

QUESTION 32
The DBA has determined that the number of OCPU assigned to an Autonomous Database does not provide sufficient performance. Which option does the DBA have in this case?

Plan for a one-hour downtime and increase the number of OCPU while database is offline

Call Oracle Cloud Support and raise a request to increase number of OCPU. Expect a downtime of approximately one hour

Open the database in OCI Console and increase the number of OCPU. No downtime required

No downtime is required as number of OCPU can be increased from OCI console, but users have to be informed that they must not use any application for at least one hour

For an “Autonomous Database,” the DBA can “Open the database in OCI Console and increase the number of OCPU. No downtime required” (C). Autonomous Database supports dynamic scaling of OCPUs online, with no service interruption, leveraging its self-managing capabilities. Options A and B involve unnecessary downtime, and D adds an unneeded user restriction. Oracle’s documentation confirms zero-downtime OCPU scaling as a key feature.

QUESTION 33
Which statements are true about built-in SQL Worksheet and Notebook? (Choose two)

Based on Apache Tomcat

Need to install client query tool for the PL/SQL

No need to install a client query tool

Quickly start running queries with built-in web-based notebooks

The “built-in SQL Worksheet and Notebook” (e.g., in Autonomous Database’s Database Actions) have two true statements: “No need to install a client query tool” (C), as it’s web-based and accessible via browser, and “Quickly start running queries with built-in web-based notebooks” (D), enabling immediate SQL execution. “Based on Apache Tomcat” (A) is not specified in documentation, and “Need to install client query tool for the PL/SQL” (B) is false due to its integrated nature. Oracle’s documentation confirms these web-based features.

QUESTION 34
Oracle Cloud and Microsoft Azure have an interconnect for workloads across cloud. Which two are also benefits this partnership and interconnect provide?

Upgrade compliance

Low Latency

Unified identity and access management

Connection to other multicloud environments

The Oracle Cloud and Microsoft Azure interconnect offers “Low Latency” (B), achieved through a high-speed, private connection between OCI and Azure data centers, reducing delays for cross-cloud workloads. It also provides “Unified identity and access management” (C), integrating Oracle IAM with Azure Active Directory for seamless user authentication. “Upgrade compliance” (A) is vague and not a documented benefit, while “Connection to other multicloud environments” (D) is not specific to this partnership. Oracle’s multicloud documentation highlights latency and identity integration as key advantages.

QUESTION 35
What is NOT a workload that can be selected when provisioning an Autonomous Database?

MySQL

JSON

Data Warehouse

APEX

When provisioning an “Autonomous Database” on Oracle Cloud Infrastructure, the supported workload types include “JSON” (B) for document-centric applications, “Data Warehouse” (C) for analytics, and “APEX” (D) for low-code application development, alongside Transaction Processing (not listed here). “MySQL” (A) is not a workload type for Autonomous Database; instead, it is a separate database service (Oracle MySQL Database Service) on OCI, not part of the Autonomous Database offering. Oracle’s documentation specifies the distinct workload options available during Autonomous Database provisioning, excluding MySQL.

QUESTION 36
What does ORDS stand for?

Oracle REST Data Services

Oracle Resilient Data Security

Oracle Rapid Data Systems

Oracle REAP Diagnosis Systems

ORDS stands for “Oracle REST Data Services,” a middleware component provided by Oracle to enable RESTful access to Oracle Database and related services. It allows developers to expose SQL queries, database objects, and stored procedures as REST APIs, facilitating integration with modern applications. Options B (“Oracle Resilient Data Security”), C (“Oracle Rapid Data Systems”), and D (“Oracle REAP Diagnosis Systems”) are not recognized terms in Oracle’s official documentation. ORDS is extensively documented in Oracle’s cloud and database resources as a critical tool for RESTful services, particularly in environments like Autonomous Database and Oracle Cloud Infrastructure (OCI).

QUESTION 37
Which statement is not the responsibility of the customer in a simple cloud management model?

Manage database servers and VM hosts

Subscribe to database servers

Everything inside of the database

Control access to customer VMs

In a simple cloud management model (e.g., Autonomous Database), “Manage database servers and VM hosts” (A) is not the customer’s responsibility; Oracle handles infrastructure management. Customers “Subscribe to database servers” (B), manage “Everything inside of the database” (C) like data and schemas, and “Control access to customer VMs” (D) where applicable. Oracle’s shared responsibility model delegates server and host management to the provider.

QUESTION 38
Which Oracle Cloud Infrastructure (OCI) Identity and Access Management (IAM) capability helps you to organize multiple users into teams?

Groups

Policies

Users

Roles

In OCI Identity and Access Management (IAM), “Groups” (A) is the capability that helps organize multiple users into teams. Groups allow administrators to assign permissions collectively to a set of users, simplifying access management. “Policies” (B) define permissions but don’t organize users, “Users” (C) are individual accounts, and “Roles” (D) are not a distinct IAM construct in OCI (unlike other clouds). Oracle’s IAM documentation identifies Groups as the mechanism for team-based organization.

QUESTION 39
Exadata is the integration of software and hardware and is available to customers on which deployments?

Only in a hybrid cloud

Only in public cloud environments

Only at the customer site

In the Oracle Cloud and customer site

“Exadata” integrates software and hardware and is available both “In the Oracle Cloud and customer site” (D). It is offered as Exadata Cloud Service (public cloud) and Exadata Cloud@Customer (on-premises), providing flexibility for hybrid deployments. “Only in a hybrid cloud” (A) is too restrictive, “Only in public cloud environments” (B) ignores Cloud@Customer, and “Only at the customer site” (C) excludes the cloud option. Oracle’s documentation confirms Exadata’s availability in both OCI and on-premises configurations.

QUESTION 40
Which two are true about the Data Catalog?

Management is required

Harvest object storage to derive schemas

Discover data using powerful search

Data Catalog does not integrate with Autonomous Database

The “OCI Data Catalog” has two true characteristics: “Harvest object storage to derive schemas” (B), as it scans OCI Object Storage to extract metadata and schemas, and “Discover data using powerful search” (C), offering robust search capabilities for data discovery. “Management is required” (A) is vague and not a defining trait, and “Data Catalog does not integrate with Autonomous Database” (D) is false, as it integrates seamlessly for metadata management. Oracle’s documentation confirms these features.

QUESTION 41
What is the FINAL release supporting the non-CDB architecture?

Oracle Database 21c

Oracle Database 19c

Oracle Database 23c

Oracle Database 18c

The final release supporting the “non-CDB (non-Container Database)” architecture is “Oracle Database 19c” (B). Oracle deprecated the non-CDB architecture starting with 20c (never fully released) and mandated the multitenant architecture (CDB with PDBs) from 21c onward. 19c, as a long-term support release, was the last to support non-CDB databases, with Oracle recommending migration to multitenant in subsequent versions like 23c. Oracle’s documentation confirms 19c as the end of non-CDB support.

QUESTION 42
What three typical data types/models are covered by Oracle’s Converged Database?

Events

Spatial

Terraform

Graph

Relational

Oracle’s “Converged Database” supports multiple data types/models, including “Spatial” (B) for geospatial data, “Graph” (D) for relationship analytics, and “Relational” (E) for traditional structured data. “Events” (A) is not a distinct data model but a use case, and “Terraform” (C) is an infrastructure tool, not a data type. Oracle’s documentation lists Spatial, Graph, and Relational among others (e.g., JSON, XML) as core converged capabilities.

QUESTION 43
Which command for the MySQL Data Service will resume OCPU billing?

Start

Stop

Restart

Backup

For the “MySQL Database Service,” the “Start” command (A) resumes OCPU billing, as it activates the database instance, incurring compute costs. “Stop” (B) halts billing by suspending the instance, “Restart” (C) is a stop-then-start sequence, and “Backup” (D) affects storage, not OCPU billing. Oracle’s MySQL Service documentation ties billing to the Start command.

QUESTION 44
Oracle Automated Machine Learning (AutoML) has options for using in-database and open-source algorithms. Which is an example of an in-database option?

REST Interface

Cognitive text

Oracle Machine Learning for Python (OML4PY) APIs

Tuning of hyperparameter

An example of an in-database option in Oracle Automated Machine Learning (AutoML) is “Oracle Machine Learning for Python (OML4PY) APIs” (C). OML4Py enables Python-based machine learning directly within the database, leveraging in-database algorithms for performance and security. “REST Interface” (A) is an access method, “Cognitive text” (B) is a feature, not an algorithm type, and “Tuning of hyperparameter” (D) is a process, not a specific option. Oracle’s documentation highlights OML4Py as a key in-database ML tool.

QUESTION 45
The Oracle Cloud Infrastructure (OCI) Data Catalog is an integral part of the Lakehouse solution. What level of data detail does Data Catalog provide when integrated with Autonomous Databases and Object Storage?

Analytic environments

Data Warehouse

Source of managed services

View of data for discovery

The “OCI Data Catalog” provides a “View of data for discovery” (D) when integrated with Autonomous Databases and OCI Object Storage in the Lakehouse solution. It serves as a metadata management service, offering a centralized view of data assets, their schemas, and relationships, enabling users to discover and understand data across the Lakehouse. “Analytic environments” (A) and “Data Warehouse” (B) refer to processing or storage constructs, not the role of Data Catalog. “Source of managed services” (C) is vague and not a documented function. Oracle’s documentation highlights Data Catalog’s role in data discovery and governance, not processing or storage.

QUESTION 46
Which Oracle Cloud Infrastructure (OCI) service is NOT available as part of Oracle Cloud Free Tier?

Autonomous Data Warehouse

Exadata DB Systems

Compute

Monitoring

“Exadata DB Systems” (B) is not available in the Oracle Cloud Free Tier. The Free Tier includes “Autonomous Data Warehouse” (A) with limited resources, “Compute” (C) instances, and “Monitoring” (D) services, but Exadata DB Systems, being a high-performance, premium offering, requires a paid subscription. Oracle’s Free Tier documentation lists eligible services, explicitly excluding Exadata.

QUESTION 47
Which of the following has expanded flexibility with shared or dedicated Exadata infrastructure?

Oracle Database Cloud Service

Oracle Exadata Cloud Service

Oracle Autonomous Database

Oracle Exalogic Cloud Service

“Oracle Exadata Cloud Service” (B) offers expanded flexibility with shared or dedicated Exadata infrastructure, allowing customers to choose between cost-effective shared resources or isolated dedicated hardware for performance and compliance needs. “Oracle Database Cloud Service” (A) is VM-based and lacks Exadata’s hardware integration, “Oracle Autonomous Database” (C) is fully managed without hardware choice, and “Oracle Exalogic Cloud Service” (D) is an outdated middleware platform, not database-focused. Oracle’s documentation highlights Exadata Cloud Service’s deployment options.
