1z0-1105-23 Exam Dumps - Oracle Cloud Infrastructure Certification Questions and Answers

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.

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.

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.

An Autonomous Database with the workload type Data Warehouse, Transaction Processing, JSON or APEX is a prerequisite of running APEX on an Autonomous Database. According to the Oracle documentation, “Oracle Application Express (APEX) is a low-code development platformthat enables you to build scalable, secure apps with world-class features that can be deployed anywhere. APEX is preconfigured and fully managed in Oracle Autonomous Database (ADB). You can use APEX on any Autonomous Database workload type: Data Warehouse (ADW), Transaction Processing (ATP), JSON (AJD), or APEX (APEX).”

Hadoop clusters cannot be run on Oracle Database 19c. Hadoop is a framework for distributed processing of large data sets across clusters of computers using simple programming models. Oracle Database 19c is a relational database management system that supports SQL and PL/SQL queries and transactions. Hadoop clusters require a different architecture and storage model than Oracle Database 19c. Oracle Database 19c does not support the Hadoop Distributed File System (HDFS) or the MapReduce programming model.
