NEW QUESTION # 73
By default, how many delegated subnets can Oracle AI Database@Azure use before a service limit increase must be requested?
Answer: B
Explanation:
Oracle AI Database@Azure has a default regional service limit of five delegated subnets . Once a deployment requires more than five delegated subnet links in a region, the customer must request a service- limit increase.
This aggregate regional limit must not be confused with the separate VNet design rule. An individual Azure VNet can contain a maximum of one delegated subnet for Oracle AI Database@Azure, but an organization can have several VNets and therefore several delegated subnets across the same region up to the default service limit.
Oracle identifies the relevant service-limit metadata as:
Service: Multicloud
Resource: Delegated Subnet Multicloud Links
Limit name: azure-delegated-subnet-count
The limit operates at regional scope. Therefore, creating additional peerings or Route Servers does not bypass it; the correct approach is to request additional service capacity through Oracle's service-limit process.
Values of 1, 3, and 10 do not represent the default regional limit.
Therefore, A. 5 is correct.

NEW QUESTION # 74
You have deployed a primary Exadata VM cluster in one Azure region and a standby in a distant paired region using Active Data Guard. Round-trip latency between the regions exceeds the threshold for synchronous redo transport, but the application requires zero data loss on regional failover. What should you configure?
Answer: A
Explanation:
Oracle Active Data Guard Far Sync is specifically designed to provide zero-data-loss protection when the physical standby database is too geographically distant for direct synchronous redo transport without unacceptable primary-database latency.
The primary database sends redo synchronously to a nearby Far Sync instance. Because the Far Sync instance is positioned within low network latency of the primary, the primary can obtain the acknowledgement required for zero-data-loss protection without waiting for communication with the distant standby. Far Sync then forwards the redo asynchronously across the higher-latency interregional connection to the remote standby.
Oracle's Oracle Database@Azure reference architecture explicitly uses this pattern: the primary sends redo in SYNC mode to its local Far Sync instance, which forwards it in ASYNC mode to the remote standby database.
Maximum Performance using ASYNC alone permits a potential data-loss window. A snapshot standby is intended primarily for temporary read/write testing. Fast-Start Failover automates role transitions but requires an Observer and does not independently solve the synchronous-transport latency problem.
Therefore, C is correct. Study Guide reference: HA and DR - Active Data Guard Far Sync and zero-data- loss cross-region protection.
NEW QUESTION # 75
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: D
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.
Study Guide reference: Migrate Oracle Databases to Oracle AI Database@Azure - ZDM CLI, evaluation mode, migration validation and prechecks.
NEW QUESTION # 76
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: C
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 # 77
You have completed onboarding using the Pay As You Go offer for Oracle AI Database@Azure. You now attempt to provision Oracle Exadata Database Service on Dedicated Infrastructure and the option isn't available. What should you do?
Answer: B
Explanation:
Oracle's current service-availability matrix states that Oracle Exadata Database Service on Dedicated Infrastructure is eligible for Private Offer only . It is not available through the Public Offer/Pay As You Go purchasing model.
Therefore, if an organization originally onboarded Oracle AI Database@Azure using the Public Offer and subsequently requires Dedicated Exadata Infrastructure, the commercial relationship must be changed by engaging Oracle Sales and obtaining the appropriate Private Offer .
A delegated-subnet service-limit increase affects networking capacity and does not enable a database service that is excluded by the selected Marketplace offer. BYOL can reduce Oracle Database licensing charges where eligible, but licensing model and Marketplace service eligibility are separate issues. Changing an Autonomous Database workload type is completely unrelated to Exadata hardware procurement.
Oracle's current service table also shows why the confusion can arise: Exadata Database Service on Exascale Infrastructure is available through both Public and Private Offers, whereas Exadata Database Service on Dedicated Infrastructure remains Private Offer only.
Therefore, A is correct.
Study Guide reference: Oracle AI Database@Azure Architecture and Onboarding - offer eligibility and Dedicated Infrastructure purchasing.
