Oracle Updated 1z0-1147 Exam Questions and Answers by sabrina

The invalid managed backup destination is the physical Zero Data Loss Recovery Appliance (ZDLRA) .

Oracle AI Database@Azure currently provides two primary managed automatic backup destinations for Exadata databases: Oracle Database Autonomous Recovery Service and OCI Object Storage . Oracle recommends Autonomous Recovery Service because it provides database-aware incremental-forever protection, policy-based retention, recoverability validation, optional real-time redo protection, and retention-lock capabilities.

Long-Term Retention is a supported capability of Recovery Service and allows selected backups to be preserved for extended compliance periods. It therefore represents a valid managed backup lifecycle option, even though technically it is a Recovery Service feature rather than an independent storage system.

The Zero Data Loss Recovery Appliance is a physical Oracle engineered system primarily used in customer data centers and appropriate Cloud@Customer architectures. Autonomous Recovery Service incorporates technologies derived from the Recovery Appliance but is delivered as a managed cloud service; these two should not be confused.

Therefore, the answer to the "NOT valid" question is B .

The uploaded study set keys D , because it attempts to preserve data inside the same geographical region while obtaining a separate fault domain.

There is, however, an important current-documentation qualification. Oracle AI Database@Azure maps an OCI Availability Domain to an Azure Availability Zone , and Oracle MAA documentation describes local Data Guard standby deployments on another Exadata infrastructure in the same or a separate Azure Availability Zone . Oracle's cross-zone Data Guard implementation explicitly requires primary and standby Oracle AI Database@Azure deployments in two supported Azure AZs.

Therefore, option D is valid only if the second OCI Availability Domain corresponds to another supported Oracle AI Database@Azure Azure AZ. If the premise is literally that Oracle AI Database@Azure is available in only one Azure AZ and cross-region replication is prohibited, current Oracle documentation does not provide a second independent Oracle AI Database@Azure site simply by selecting an unmapped OCI AD.

For the uploaded question's intended key, the answer remains D , but the architecture should be treated with this deployment-availability condition.

===============

Oracle Maximum Availability Architecture Silver adds Oracle Real Application Clusters (RAC) to the MAA Bronze foundation. RAC provides active-active database clustering across multiple database-server nodes while all instances access the same underlying database storage.

For Exadata Database Service on Dedicated Infrastructure, RAC supplies localized protection against database-instance and database-server failure. If one RAC instance or compute node fails, services and connections can relocate to surviving instances that are already running. RAC also materially reduces or eliminates database downtime for many planned maintenance operations.

Oracle Active Data Guard addresses a different availability layer: it maintains a physically separate standby database and is primarily used for site, availability-zone, or regional disaster recovery. Oracle GoldenGate performs logical data replication and integration, while Oracle Sharding distributes data across independent database shards for scale and fault isolation.

Oracle's current MAA documentation explicitly identifies RAC as the technology introduced at the Silver tier and recommends Exadata as the optimized RAC platform.

Therefore, B is correct.

Purchasing and subscribing to the Oracle AI Database@Azure Private Offer establishes the Azure Marketplace commercial relationship, but it does not complete the technical onboarding process. The next mandatory stage is linking the Azure subscription to an Oracle Cloud Infrastructure tenancy . Oracle refers to this process as multicloud linking.

For a Private Offer, the customer can either create a new OCI tenancy or link an existing eligible OCI tenancy. The linked OCI account supplies the Oracle-side control-plane context used for database resources, including management of container databases and pluggable databases and delivery of Oracle infrastructure and software maintenance services. Only after the Purchase and Link stages have been completed and the account relationship is verified can normal Oracle AI Database@Azure resource provisioning proceed.

Azure Key Vault integration is optional and relates to customer-managed TDE keys. Data Guard is configured after database infrastructure exists, and an Autonomous Database is not a prerequisite for Exadata.

Therefore, D is correct. Study Guide reference: Oracle AI Database@Azure Architecture and Onboarding — Purchase, Link, Verify, and OCI tenancy association.
