NEW QUESTION # 14
Which two Azure network components are required to construct a secure Hub-and-Spoke topology with a central firewall for Oracle AI Database@Azure? (Choose two.)
Answer: B,C
Explanation:
A Hub-and-Spoke design separates shared connectivity and security services from workload networks. For Oracle AI Database@Azure, Oracle documents a Hub VNet that hosts centralized services such as Azure Firewall or a third-party NVA and a dedicated spoke VNet for Oracle AI Database@Azure containing the delegated subnet .
The Oracle database spoke is connected to the hub through Azure VNet peering. User-Defined Routes are then used to direct traffic through the hub's firewall or NVA when centralized inspection is required.
Application spokes can similarly route database-bound traffic toward the security appliance, while return routes on the database spoke preserve the required symmetric traffic path.
Azure VM Scale Sets are application-compute constructs and do not form the essential Hub-and-Spoke network topology. OCI FastConnect is an OCI/hybrid connectivity capability rather than the Azure-side Hub- and-Spoke component described by this scenario.
Therefore, B and C identify the essential architecture: the Oracle database workload is isolated in a spoke VNet, while the Hub VNet provides centralized traffic inspection and security enforcement.

NEW QUESTION # 15
Which ZDM migration workflow uses an initial load followed by GoldenGate-based change data capture to achieve near-zero downtime?
Answer: C
Explanation:
Logical Online Migration combines an initial logical data load with Oracle GoldenGate change data capture to minimize production downtime.
The initial target database is populated using Oracle Data Pump export and import. Because that data movement can take a substantial amount of time for large databases, Oracle GoldenGate continuously captures transactions committed on the source while the initial load is being performed. Those transactions are subsequently applied to the target, allowing the destination to converge with the production source while the application remains active.
When synchronization reaches the required state, ZDM orchestrates the final migration phases and application cutover. The downtime requirement is therefore concentrated around the final transition rather than the entire export/import window.
Logical Offline uses Data Pump without continuous GoldenGate synchronization. Physical Online uses RMAN-based target instantiation and Oracle Data Guard redo synchronization instead of GoldenGate.
Physical Offline similarly relies on physical backup/restore processes and does not use logical change-data capture.
Thus, B. Logical Online Migration is correct.

NEW QUESTION # 16
When using Zero Downtime Migration (ZDM) to migrate a schema to an Autonomous Database target on Oracle Database@Azure, what is the default target tablespace mapping behavior?
Answer: B
Explanation:
For migrations to Autonomous Database Shared/Serverless , ZDM applies automatic tablespace remapping because users cannot freely reproduce arbitrary source tablespaces in the same manner as on a customer- managed Oracle Database.
Oracle's ZDM documentation states that for an Autonomous Database Shared Infrastructure target, source tablespaces are automatically remapped to the predefined DATA tablespace by default. In FULL-mode migration to Autonomous Database Serverless, Oracle likewise specifies DATA as the default remap target because general user-created tablespace creation is not supported in that migration model.
This prevents source schema objects from being imported into unavailable tablespaces. SYSTEM and SYSAUX are Oracle-maintained dictionary tablespaces and must not be used as ordinary user-data destinations. USER_DATA is not the standard default target identified by ZDM. Preserving every source tablespace name is also incompatible with the default Autonomous Serverless storage model.
ZDM can support explicit metadata remapping where appropriate, but absent such an override, the default is DATA.
Therefore, D is correct.

NEW QUESTION # 17
A financial services firm is migrating its legacy core banking application to Microsoft Azure to leverage Azure's extensive app modernization and containerization ecosystem. However, the firm's strict service-level agreements (SLAs) for transactional throughput and database availability require keeping the system on Oracle Exadata Database Service. The database must remain in OCI to leverage native OCI management, while the containerized application microservices must be hosted on Azure. To minimize latency and egress costs, the architect must choose the OCI-recommended multicloud use-case pattern that supports running the application front-end and the relational database on different public clouds connected via private, high-speed links. Choose ONE.
Answer: C
Explanation:
The scenario directly matches Oracle's documented multicloud use case of running applications in one cloud and databases in another , also described here as an application and database split-stack architecture .
This design allows an organization to place its application tier in the cloud offering the preferred application- development ecosystem while retaining the database on the cloud platform offering the required database capabilities. In this case, Azure provides containerization and application modernization services, while OCI continues hosting Oracle Exadata Database Service for high transaction throughput, database availability, and Oracle-native operational control.
Private, high-bandwidth intercloud connectivity is critical because application-to-database latency directly affects transaction response time. Keeping data movement predictable and minimizing unnecessary public- internet routing also improves security and can reduce data-transfer overhead.
Horizontal workload distribution instead spreads workloads across clouds rather than separating application and database tiers. Production/development separation addresses lifecycle environments, while SaaS/ERP integration addresses data interoperability rather than a transactional split-stack application.
Therefore, C is the correct architectural pattern.

NEW QUESTION # 18
An enterprise configures an Azure User-Defined Route (UDR) with a prefix of 10.0.0.0/16 to route traffic to an Oracle AI Database@Azure instance that resides in a delegated subnet sized at 10.0.0.0/24. What is the consequence of configuring this less specific UDR prefix?
Answer: D
Explanation:
Oracle's Hub-and-Spoke design guidance defines an important UDR rule for Oracle AI Database@Azure delegated subnets: the route prefix must be at least as specific as the delegated subnet CIDR . A /24 delegated subnet therefore cannot be reliably represented by a broader /16 route when the architecture requires the delegated subnet-specific path.
The less-specific route can fail to take precedence over more-specific system or service routes. This creates the possibility that traffic takes one route toward the database but returns through a different route. Such asymmetric routing is especially problematic with Azure Firewall or an NVA because stateful firewalls expect both directions of a connection to traverse the same inspection point. If the return packet follows a different path, the firewall can drop the session.
A UDR has no mechanism for duplicating VNICs, changing SQL*Net encryption, or resizing the underlying subnet. It simply influences Layer-3 forwarding.
Therefore, A accurately describes the documented routing consequence.
