Oracle 1z0-1105-23 Oracle Cloud Data Management 2023 Foundations Associate Exam Practice Test

View of data for discovery is the level of data detail that Data Catalog provides when integrated with Autonomous Databases and Object storage. According to the Oracle documentation6, “Oracle Cloud Infrastructure Data Catalog is a fully managed, self-service data discovery and governance solution for your enterprise data. Data Catalog helps you maximize the value of your data assets by providing a rich set of capabilities that enable you to discover, explore, organize, enrich, and trace data lineage on various types of data sources.” Data Catalog provides a view of data for discovery by using metadata to create an informative and searchable inventory of all data assets in an organization.

Customers are responsible for managing databases and customer VMs when they are using the Exadata Cloud Service. According to the Oracle documentation7, “Customers have full control over their databases running on Exadata Cloud Service, including root access for database servers.” Additionally, according to the Oracle documentation8, “Customers can create customer VMs on Exadata Cloud Service database servers for their own use.”

These are three options that can be selected when using the console to create an autonomous database on an Autonomous Exadata Cloud@Customer. According to the Oracle documentation1, “When you create an Autonomous Database on Autonomous Exadata Cloud@Customer, you specify the following information: Database name, Database display name, Workload type, Admin password, License type, Number of OCPUs, Storage (TB), and Tags (optional).” The workload type can be either transaction processing or data warehouse.

These are two characteristics of CI/CD, which is a set of practices that automate the building, testing, and deployment stages of software development. According to the Red Hat website9, “CI/CD introduces ongoing automation and continuous monitoring throughout the lifecycle of apps, from integration and testing phases to delivery and deployment.” This means that CI/CD aims to reduce manual tasks and increase efficiency and reliability across the development life cycle. According to the IBM blog10, “Continuous integration (CI) is an automation process for developers. Successful CI means new code changes to an app are regularly built, tested, and merged to a shared repository.” This means that CI/CD enables developers to integrate their code changes frequently and automatically, ensuring code quality and consistency.

These two statements are true regarding MySQL Database Service HeatWave. According to the Oracle website3, “HeatWave is a high-performance in-memory query accelerator for MySQL Database Service on Oracle Cloud Infrastructure. It is designed to accelerate analytics workloads (OLAP) and increase the performance of your MySQL databases by orders of magnitude.” Additionally, according to the Oracle website4, “HeatWave uses machine learning to automate operations, increasing DBA productivity and reducing costs. HeatWave AutoML enables developers and data analysts to build, train, deploy, and explain machine learning models in MySQL HeatWave without moving data to a separate machine learning service.”

This statement can be detected by monitoring of access to sensitive data, because it queries all the data from the EMPLOYEES table, which may contain personal or confidential information about the employees, such as name, address, salary, or performance. Monitoring access to sensitive data can help protect the data from unauthorized or malicious use, and ensure compliance with data privacy regulations.

OCI REST APIs and OCI Command-line Interface (CLI) are two methods that you can use to create or modify Oracle Cloud Infrastructure resources. According to the Oracle documentation, “The Oracle Cloud Infrastructure APIs are typical REST APIs that use HTTPS requests and responses. You can use these APIs to interact with your cloud resources programmatically.” Additionally, according to the Oracle documentation, “The OCI CLI is a tool that enables you to interact with Oracle Cloud Infrastructure services from the command line.”

Focuses on creation of indexes and optimized for response time are two characteristics of Autonomous Transaction Processing (ATP). According to the Oracle documentation,“Autonomous Transaction Processing is a database service that is optimized for transaction processing or mixed workloads. It delivers the best experience for mission-critical applications that require high performance, high concurrency, and low latency. Autonomous Transaction Processing automatically creates indexes, materialized views, and partitions based on the workload.” Additionally, according to the Oracle documentation, “Autonomous Transaction Processing is optimized for response time. It uses a combination of caching, in-memory columnar format, and result set caching to deliver fast response times.”

Regulations that prevent moving data into the public cloud and putting data in the cloud would break data residency rules are two typical reasons why customers cannot move their database into the public cloud. Some organizations may have legal, compliance, or business policy requirements that restrict where their data can be stored or processed. For example, some regulations may require that data be stored within a certain country or region, or that data be encrypted or anonymized before being transferred to the cloud. Moving data to the public cloud may violate these regulations or introduce additional risks or costs for the customers.

This statement is true about MySQL Database Service. According to the Oracle documentation3, “MySQL Database Service is a fully managed Oracle Cloud Infrastructure native service, developed, managed, and supported by the MySQL team in Oracle. Oracle automates tasks such as backup and recovery, and database and operating system patching. You are responsible solely for managing your data, schema designs, and access policies.”

Object Storage (standard) is the OCI storage service that can be used to store application backups which can be stored for months, but retrieved immediately based on business needs. According to the Oracle documentation1, “Object Storage is a highly scalable, durable, and available cloud-based storage service that provides a cost-effective way to store and manage large amounts of unstructured data such as images, videos, and log files. Object Storage supports standard HTTP operations such as GET, PUT, and DELETE, as well as advanced features such as encryption, data replication, lifecycle policies, and pre-authenticated requests.” Object Storage (standard) offers high performance and low latency for frequent data access.

AutoUpgrade is the Oracle recommended way to upgrade databases. According to the Oracle documentation, “AutoUpgrade is an Oracle-supplied tool that automates the upgrade process for Oracle Database releases 12.2, 18c, and 19c. AutoUpgrade can upgrade multiple databases in parallel and can also perform cross-platform migrations. AutoUpgrade is the recommended tool for upgrading your database.”

OCI Data Flow is the Lakehouse service that you should use for serverless Spark processing. According to the Oracle documentation, “Oracle Cloud Infrastructure Data Flow is a fully managed big data service that lets you run Apache Spark applications with no infrastructure to deploy or manage. Data Flow lets you create, run, and manage Apache Spark applications with minimal coding and no infrastructure provisioning or management.”

Loading data using FTP is not an option in Database Actions to load data into Autonomous Database. According to the Oracle documentation5, “On the Database Actions Data Load pageyou can choose to load data from a file on your local device, from cloud storage, or from a database. You can also choose to explore the data in your Oracle Autonomous Database.” There is no mention of FTP as a source for loading data.

These are two statements that are true when deciding which Oracle Cloud Infrastructure (OCI) region to register an Exadata Cloud@Customer infrastructure in. According to the Oracle documentation5, “When you register an Exadata Cloud@Customer infrastructure in an OCI region, consider any business policies or regulations that preclude the use of a particular region.” This means that you should be aware of any legal or compliance requirements that might limit your choice of OCI regions for Exadata Cloud@Customer. According to the Oracle documentation6, “Consider the physical proximity of the region you register the infrastructure in to your data center. The closer they are physically located, the lower the network latency between them.” This means that you should also consider the network performance and availability when choosing an OCI region for Exadata Cloud@Customer.
