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

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 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.”

Groups is an Oracle Cloud Infrastructure (OCI) Identity and Access Management (IAM) capability that helps you to organize multiple users into teams. According to the Oracle documentation4, “Groups are collections of users who need the same type of access to a particular set of resources. You can use groups to organize users and apply policies to them as a group.”

Changing COMPATIBLE after upgrades is one of the scenarios when you should change COMPATIBLE. According to the Oracle blog post7, “COMPATIBLE needs to be adjusted only once after you completed your last database upgrade.” The blog post also explains that changing COMPATIBLE requires a restart of the database and that it should not be changed before upgrades or patching or after downgrades.

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.

Compartments are a feature that allows you to logically group and isolate your Oracle Cloud Infrastructure resources. According to the Oracle documentation2, “Compartments are a fundamental component of Oracle Cloud Infrastructure that allow you to create a heterogeneous collection of resources for organization, security isolation, and access control.To learn more about compartments, see Managing Compartments . Organize your cloud resources in logically separate compartments, for the purposes of measuring usage and billing, controlling access, and isolating resources.”

These are two key characteristics of Oracle Autonomous Database. According to the Oracle documentation10, “Autonomous Database provides an easy-to-use, fully autonomous database that scales elastically, delivers fast query performance, and requires no database administration.” As a service, Autonomous Database handles all the tasks related to provisioning, patching, upgrading, scaling, backup, and recovery of the database, so that customers do not need to manage anything. Additionally, Autonomous Database offers lowercost compared to other cloud database services by providing features such as auto scaling, performance optimization, and pay-per-use pricing model.

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.

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.

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.”

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.
