質問 # 38
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.
正解：A
解説：
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.

質問 # 39
Your team is configuring a ZDM Physical Offline migration to Exadata on Oracle Database@Azure, but the target database host cannot read the RMAN backup files mounted on the Azure Files NFS share. What must you verify to resolve this storage access and permission issue?
正解：D
解説：
ZDM Physical Offline migration can use an Azure Files NFS share as the common location for RMAN backup files. Because the NFS share is mounted on both the source and target database hosts, file ownership must be interpreted consistently on both systems.
NFS using Unix-style permissions identifies users primarily by their numeric UID rather than simply by the textual account name. Oracle's ZDM migration guidance explicitly states that the NFS-mounted path is readable by the target database user only when the source database user's UID matches the target database user's UID. Thus, two hosts can both have an account named oracle, but if those accounts have different numeric UIDs, files created by one host can appear to be owned by a different identity on the other.
Port 443 and SQL*Net listener port 1521 address network/API or database-client connectivity; neither resolves Unix file ownership on an NFS mount. Active Directory Domain Services authentication is likewise not the controlling permission model for the documented NFS migration workflow.

質問 # 40
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.)
正解：A、C
解説：
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.
質問 # 41
Which two statements are true about identity federation for Oracle AI Database@Azure? (Choose two.)
正解：A、D
解説：
Identity federation is optional in Oracle AI Database@Azure. Oracle states that most normal database operations can be performed through the Azure environment without federation. Federation becomes particularly useful when administrators must enter the OCI Console for Oracle-specific database management tasks and want to authenticate using their corporate Microsoft Entra ID credentials.
The uploaded study material also identifies the user-record requirement of a last name and valid email address. Oracle's current federation documentation provides a slightly more detailed rule: provisioning users into OCI requires First Name, Last Name and Display Name , plus Email Address when the OCI Identity Domain is configured to require email addresses . Legacy Oracle Database@Azure federation documentation states the last-name/valid-email requirement directly.
Federation does not replace the OCI tenancy. Oracle AI Database@Azure always requires an OCI tenancy- either an existing tenancy linked through a Private Offer or a new tenancy created during onboarding.
Therefore, A and B are the intended answers.

質問 # 42
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?
正解：D
解説：
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.
