NEW QUESTION # 72
What is the allowed range of days for the automatic backup retention period when configuring an instance of Oracle Autonomous AI Database Serverless in Oracle AI Database@Azure?
Answer: A
NEW QUESTION # 73
You have created a delegated subnet for an Exadata Infrastructure resource in Availability Zone 1. You now need to provision a second Exadata Infrastructure resource in Availability Zone 2 for disaster recovery. What should you do?
Answer: C
Explanation:
Cross-availability-zone Oracle AI Database@Azure disaster recovery requires separate networking constructs for the primary and standby deployments. Oracle's Data Guard prerequisite documentation specifies two Azure VNets , with each VNet containing one Oracle AI Database@Azure delegated subnet , when configuring Data Guard between different availability zones in the same Azure region.
A separate delegated subnet ensures that each Exadata deployment receives the correct network attachment, address space, routing, and zone-aligned connectivity. Oracle also requires the associated VNet address spaces to be non-overlapping.
Reusing the AZ1 delegated subnet for infrastructure located in AZ2 would therefore conflict with the supported topology. Self-peering a subnet is not an Azure networking construct and would provide no meaningful isolation. Removing delegation would be counterproductive because delegation to Oracle's database resource provider is fundamental to provisioning Oracle AI Database@Azure networking.
Thus, A is the correct deployment pattern.

NEW QUESTION # 74
Which two Oracle high availability and data replication technologies does Oracle Zero Downtime Migration (ZDM) orchestrate when performing online migrations, both physical and logical, to Oracle Database@Azure? (Choose two.)
Answer: B,C
Explanation:
Oracle Zero Downtime Migration is Oracle Maximum Availability Architecture's recommended orchestration framework for moving Oracle databases while minimizing production interruption. For physical online migration , ZDM uses Oracle Data Guard. The target database is instantiated as a physical standby, redo generated on the source is transported and applied to the target, and ZDM coordinates the eventual switchover. Oracle documentation for Oracle Database@Azure specifically states that physical online migration uses direct data transfer, Restore From Service, and Oracle Data Guard to keep source and target synchronized.
For logical online migration , the underlying synchronization technology is Oracle GoldenGate. Oracle Data Pump provides the initial logical export/import, after which GoldenGate captures ongoing source transactions and applies them to the target until cutover. This workflow can also accommodate scenarios involving different database versions or platforms.
Oracle Sharding is an application/data-distribution architecture rather than ZDM's replication mechanism. Far Sync is a Data Guard component for specialized zero-data-loss configurations but is not the primary technology identified for ZDM migration orchestration.
Study Guide reference: Migrate Oracle Databases to Oracle AI Database@Azure - ZDM physical online migration, logical online migration, Data Guard, GoldenGate, Data Pump.
NEW QUESTION # 75
Your organization is migrating a critical core banking system from an on-premises Oracle Database 12c (12.1.0.2) on IBM AIX to Oracle Exadata Database Service on Dedicated Infrastructure (ExaDB-D) on Oracle Database@Azure. The target database on ExaDB-D must be provisioned on Oracle Database 19c, requiring a cross-platform and cross-version migration. Because this is a 24/7 billing system, the business mandates that the application downtime must be limited to only the few minutes required for the final switchover. The migration architect requires a workflow that performs initial schema loading via Data Pump and utilizes real-time transaction replication to keep the target in sync until switchover. As the migration architect, which Zero Downtime Migration (ZDM) workflow satisfies all of these requirements? Choose ONE.
Answer: A
Explanation:
The required workflow is ZDM Logical Online Migration . The defining requirements are cross-platform migration, database-version change, Data Pump initial loading, ongoing transaction replication, and minimal cutover downtime.
ZDM Logical Online uses Oracle Data Pump to establish the initial target data set and Oracle GoldenGate to capture and replicate transactions occurring on the source while the bulk migration is underway. Once the target is synchronized, ZDM coordinates the final cutover, reducing application interruption to the controlled switchover period.
This logical model is appropriate for migrations such as IBM AIX to Linux-based Exadata because logical migration is not dependent on source and target having identical physical database-file formats or endian architectures. It also accommodates supported cross-version migrations.
Logical Offline also uses Data Pump but does not maintain continuous GoldenGate synchronization and therefore requires substantially greater application downtime. Physical migration uses RMAN/Data Guard and is constrained by physical compatibility requirements, making it unsuitable for the described cross-platform transformation.
Thus, B is correct.

NEW QUESTION # 76
An administrator is preparing to migrate an on-premises database to Oracle Database@Azure and runs the zdmcli migrate database command with the -eval option. What is the outcome of executing this command with this specific option?
Answer: A
Explanation:
The -eval option invokes the evaluation workflow of Oracle Zero Downtime Migration rather than executing the production migration. Oracle specifically directs administrators to use ZDMCLI migrate database ... -eval to evaluate the migration process, including prerequisite checks, source/target connectivity verification, configuration validation, and applicable pre-migration assessment phases.
The resulting job is an evaluation job rather than a migration job that performs database movement. This distinction is reflected throughout ZDM command handling: ZDM can query evaluation jobs separately from actual migration jobs, and the evaluation workflow is intended to identify prerequisite or configuration failures before production data movement begins.
The option does not create a mock standby or execute a simulated Data Guard switchover. It also does not begin an offline migration and stop before the copy phase. CPAT may participate in migration-readiness assessment depending on ZDM version and command options, but -eval is not an installation command for CPAT.
Consequently, A correctly represents the effect: an EVAL-type workflow performs migration prechecks and validation without executing the actual migration.
