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

 Exadata Cloud Service and Autonomous Database are two target database environments that provide both high availability (HA) and disaster recovery (DR) options in the cloud. Exadata Cloud Service is a fully managed Oracle Database service that runs on Exadata infrastructure in the cloud. It offers high performance, scalability, availability, security, and reliability for all types of database workloads. It also supports various HA and DR options, such as Oracle Real Application Clusters (RAC), Oracle Data Guard, Oracle Active Data Guard, Oracle GoldenGate, and Oracle Zero Data Loss Recovery Appliance Cloud Service. Autonomous Database is a self-driving, self-securing, and self-repairing cloud database service that automates provisioning, configuring, securing, tuning, scaling, patching, backing up, and repairing of databases without human intervention. It also provides built-in HA and DR features based on Oracle Maximum Availability Architecture (MAA), such as transparent application continuity, automatic failover to standby databases or regions, automatic backups to object storage, point-in-time recovery using restore points or backups.

Security and support compliance are two important reasons to upgrade and patch your Oracle Database. According to the Oracle blog3, “Security is one of the most important reasons to patch your database. Every quarter Oracle releases security patches as part of the Critical Patch Update (CPU) program. These patches fix vulnerabilities in the database software that could be exploited by malicious attackers.” Additionally, according to the Oracle blog4, “Support compliance is another reason to patch your database. Oracle provides different levels of support for different versions of the database software. To be eligible for certain support services, such as Extended Support or Sustaining Support, you need to apply the latest patches available for your version.”

Nosql-keys is not a resource type for NoSQL Database Cloud Service. According to the Oracle documentation, “Oracle NoSQL Database Cloud Service supports three resource types: nosql-tables, nosql-rows, and nosql-indexes. These resource types are used to define policies that control access to NoSQL tables and data.”

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.

ORDS stands for Oracle REST Data Services, which is a Java application that enables developers to access and manipulate data in Oracle Database using RESTful web services. According to the Oracle documentation2, “Oracle REST Data Services (ORDS) bridgesHTTPS and your Oracle Database. A mid-tier Java application, ORDS provides a Database Management REST API, SQL Developer Web, a PL/SQL Gateway, SODA for REST, and the ability to publish RESTful Web Services for interacting with the data and stored procedures in your Oracle Database.”

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.

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.”

 Persistent memory is the resource that RDMA accesses in Exadata X8M. According to the Oracle website1, “Exadata X8M uses RDMA over Converged Ethernet (RoCE) to directly access the persistent memory in storage servers, bypassing the OS, IO, and network software stacks. This reduces IO latency by up to 10X compared to the previous generation of Exadata.”

This statement is true about how the Converged Database helps to access data using an API. According to the Oracle documentation5, “Oracle REST Data Services (ORDS) makes it easy to develop modern REST interfaces for relational data in the Oracle Database and the Oracle Database 18c JSON Document Store. A mid-tier Java application, ORDS maps HTTP(S) verbs (GET, POST, PUT, DELETE, etc.) to database transactions and returns any results formatted using JSON.” ORDS can automatically generate RESTful services for tables and views in the database or expose custom REST APIs using SQL or PL/SQL.

Compliance for use of specific geographies for data sovereignty laws and workload utilization of specific services are two advantages of a multicloud strategy. A multicloud strategy allows organizations to use cloud services from more than one public cloud provider to run their applications. By doing so, they can achieve various benefits such as:

• Compliance for use of specific geographies for data sovereignty laws: Some countries or regions may have regulations that require data to be stored or processed within their borders or jurisdictions. A multicloud strategy can help organizations comply with these laws by choosing cloud providers that have local presence or availability zones in the desired locations.
• Workload utilization of specific services: Different cloud providers may offer different types of services or features that suit different workloads or requirements better than others. A multicloud strategy can help organizations leverage the best-of-breed solutions from each provider for their specific needs, such as performance, scalability, security, or cost-effectiveness.
