NEW QUESTION # 100
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: D
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 # 101
You have provisioned two VNets for Oracle AI Database@Azure in the same Oracle Availability Zone. One VNet uses advanced network features and the other uses default networking, and you now want to peer them.
What should you expect?
Answer: A
Explanation:
This configuration is explicitly identified as unsupported in Microsoft's Oracle AI Database@Azure network- planning guidance. If two Oracle AI Database@Azure VNets are deployed in the same Oracle Availability Zone and one uses Advanced Networking while the other uses the default networking implementation, VNet peering between them can introduce asymmetric routing .
Asymmetric routing occurs when outbound and return traffic traverse different network paths. This is particularly problematic with stateful network elements and the differing routing models associated with the two Oracle AI Database@Azure network implementations. The result can be data-plane traffic loss toward the VNet using Advanced Networking.
VNet peering itself does not upgrade a previously provisioned VNet to Advanced Networking, nor does it downgrade the Advanced Networking environment. Advanced Networking capability is determined by the feature configuration and the state of the delegated subnet before Oracle resources/VNICs are provisioned.
Therefore, the two environments should not be directly peered in this mismatched state. The correct answer is A .

NEW QUESTION # 102
You are configuring a cross-region disaster recovery topology for an Exadata Database Service deployment on Oracle Database@Azure and need to connect the primary database VCN to the standby database VCN.
What OCI network resource limitation necessitates the creation of a second VCN acting as a Hub VCN to establish this regional peering link?
Answer: B
Explanation:
Oracle's cross-region Oracle Database@Azure reference architecture requires an additional Hub VCN because each OCI VCN can be attached to only one Dynamic Routing Gateway (DRG) at a time.
The Oracle-managed database VCN associated with an Exadata VM Cluster already uses a DRG as part of the Oracle Database@Azure network architecture. Cross-region VCN peering also requires DRG-based remote peering. Because a second DRG cannot simply be attached to the existing database VCN, Oracle introduces a separate Hub VCN with its own DRG. The database VCN is locally connected to the Hub VCN, and the Hub DRGs establish the cross-region remote peering connection.
OCI documentation independently confirms that one VCN can attach to only one DRG, whereas a single DRG can support many VCN attachments. A VCN can also have multiple Local Peering Gateways, so option B is technically incorrect.
The limitation is therefore architectural rather than a restriction caused by Azure subnet delegation or tenancy boundaries.

NEW QUESTION # 103
Which two statements are true about the delegated subnet used by Oracle AI Database@Azure? (Choose two.)
Answer: C,D
Explanation:
Oracle's current network guidance defines two important delegated-subnet constraints. First, each Azure VNet can contain a maximum of one Oracle AI Database@Azure delegated subnet . Second, a single delegated subnet can support multiple VM Clusters , provided IP capacity and availability-zone constraints are satisfied.
Oracle clarifies that multiple VM Clusters from the same Exadata Infrastructure can share a delegated subnet.
VM Clusters belonging to different Exadata Infrastructure resources can also share one when those infrastructure resources reside in the same availability zone .
However, Exadata Infrastructure resources located in different availability zones cannot share the same delegated subnet. Oracle identifies such a configuration as producing a suboptimal network path and requires separate delegated networking for cross-zone deployments.
The delegated subnet also uses Azure private address space; it is not required to use-and should not be designed around-a public IPv4 CIDR range.
Therefore, A and C are correct.

NEW QUESTION # 104
Which OCI Identity and Access Management (IAM) policy must be added to your OCI tenancy to prevent
404 NotAuthorizedOrNotFound errors when default OCI tags are automatically generated during Exadata VM cluster creation in Oracle AI Database@Azure?
Answer: B
Explanation:
Oracle documents a specific 404 NotAuthorizedOrNotFound condition that can occur during Exadata VM Cluster creation when the selected private DNS zone does not already contain tags. Oracle then attempts to generate the default OCI oracle-tags, but the multicloud service principal must have permission to use the associated tag namespace.
The required policy statement is:
Allow any user to use tag-namespaces in tenancy where request.principal.type = 'multicloudlink' Oracle's current troubleshooting guidance also requires the companion permission:
Allow any user to manage tag-defaults in tenancy where request.principal.type = 'multicloudlink' The crucial detail is that the provisioning operation executes under the multicloudlink principal type , not an ordinary administrator group or a principal with request.user.id='multicloud'. Merely granting inspect permission is insufficient because the service must actually apply the tag namespace/defaults.
Thus, among the supplied options, C is the required policy statement.
