1z0-1105-23 Oracle Cloud Data Management 2023 Foundations Associate Questions and Answers

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.

SODA (Simple Oracle Document Access) is the set of NoSQL-style APIs that can be used in Autonomous JSON Database. According to the Oracle documentation, “SODA provides a set of APIs for various application-development languages and for RESTful web services that let you create and store collections of JSON documents in an Oracle Database without needing any knowledge of SQL or how the data is stored in the database.”

Connect (1Gbps public peering) is not an Always Free resource available for provisioning in your tenancy. According to the Oracle documentation5, “All Oracle Cloud Infrastructure accounts (whether free or paid) have a set of resources that are free of charge for the life of the account.” The list of Always Free resources includes Infrastructure Certificates, Compute VMs, Block Volumes Storage, Object Storage, Resource Manager, OCI Bastions, Databases, NoSQL Database, Observability and Management tools, Flexible Load Balancer, Outbound Data Transfer, Virtual Cloud Networks (VCN), VCN Flow Logs, and Site-to-Site VPN. Connect (1Gbps public peering) is not among these resources.

Oracle Database 19c is the final release supporting the non-CDB architecture. According to the Oracle documentation1, “Starting with Oracle Database 21c, non-CDB architecture is desupported. You must upgrade a non-CDB Oracle Database to a PDB on a CDB.” A CDB is a container database that can host multiple pluggable databases (PDBs) that share the same resources and memory.

NoSQL Service does not provide data processing on OCI Lakehouse. According to the Oracle website5, “Oracle Lakehouse provides extensive data processing capabilities, to accommodate the migration of existing architectures or the creation of new, agile ones. You can use Autonomous Database for SQL processing; Big Data Service for Hadoop/Spark processing; OCI Data Flow for serverless Spark processing; and OCI Data Integration for data movement.” NoSQL Service is a fully managed database service that provides fast and predictable performance for simple queries on flexible schemas.

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.

This option is the correct way to increase the number of OCPU assigned to an Autonomous Database. According to the Oracle documentation2, “You can scale your Autonomous Database on demand by adding CPU cores or storage. You can also enable auto scaling to allow your Autonomous Database to automatically use up to three times more CPU and IO resources than its allocated CPU core count.” The scaling operation does not require any downtime or affect the availability of the database.

Use graphical user interfaces and configuration and focus on business requirements are two main features of APEX’s low code platform. According to the Oracle website, “Oracle APEX is a low-code development platform that enables you to build scalable, secure enterprise apps with world-class features that can be deployed anywhere. With APEX, you can create modern web apps with minimal coding using intuitive graphical interfaces and declarative configuration.” Additionally, according to the Oracle website, “Oracle APEX empowers developers to focus on solving business problems rather than building low-level code.”

This statement is true about moving VM DB systems from one compartment to another. According to the Oracle documentation3, “To move resources between compartments, resource users must have sufficient access permissions on the compartment that the resourceis being moved to, as well as the current compartment.” The documentation also provides a step-by-step guide on how to move a DB system to another compartment using the Oracle Cloud Infrastructure Console.

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.”

OCI Block Volumes is the service used by default by the MySQL Database Service to store user data to make it more resistant to failures. OCI Block Volumes provides high-performance block storage volumes that can be attached to MySQL DB systems running on OCI Compute instances. Block volumes are always encrypted at rest using AES-256 encryption keys. Block volumes also support backup and restore operations using snapshots or clones that can be used for disaster recovery or testing purposes.

Assess is the security control area that determines if there is sensitive data in a system. According to the Oracle documentation2, “The Assess security control area includes activities that help you identify and classify sensitive data, assess your security posture, and monitor compliance with security standards and regulations.”

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.
