質問 # 47
In the Oracle AI Database@Azure architecture, which resource provides the OCI infrastructure components with network connectivity into a customer's Azure Virtual Network?
正解：C
解説：
The delegated subnet is the Azure networking construct that enables Oracle-managed database resources to connect directly into the customer's Azure Virtual Network.
During Oracle AI Database@Azure provisioning, a subnet in the customer's VNet is delegated to the Oracle database resource provider. This delegation permits Oracle-managed networking components and database VNICs to participate in the Azure network while preserving the managed-service boundary between customer- owned Azure networking and Oracle-operated database infrastructure.
Applications can then connect privately and with low latency to the Oracle database through addresses associated with that delegated subnet. The customer can also apply supported Azure routing and security constructs around the VNet design.
A Local Peering Gateway connects OCI VCNs within an OCI region. A Dynamic Routing Gateway provides OCI routing between VCNs, on-premises environments, or remote networks. A Service Gateway provides private connectivity from an OCI VCN to supported Oracle services. None of these is the Azure-side resource that places Oracle database networking into the customer's VNet.
Thus, C. Delegated subnet is correct.

質問 # 48
You are configuring a Network Anchor in the Azure Portal and want to enable the "Replicate DNS Private zones during DB creation" option to automatically copy private zones from OCI to Azure. Which database service must be associated with the Network Anchor to make this specific DNS option available?
正解：A
解説：
The Network Anchor abstraction establishes the mapping between Azure networking resources and corresponding OCI networking constructs. It is particularly important for services that use the newer multicloud anchor model, allowing an Azure VNet and delegated subnet to be associated consistently with Oracle-managed resources.
Oracle's DNS documentation explicitly restricts the Network Anchor DNS-resolution capability in question to Oracle Base Database Service . Network Anchors can provide DNS integration between Azure and OCI, including inbound and outbound resolution paths. Depending on the configuration, DNS listening and forwarding functionality can be enabled so resources on either side of the multicloud boundary can resolve the required private names.
The question's "Replicate DNS Private zones during DB creation" behavior belongs to this Base Database Service Network Anchor DNS workflow. Exadata Database Service on Dedicated Infrastructure and Exadata Database Service on Exascale Infrastructure use their documented Exadata networking and DNS provisioning mechanisms. Autonomous AI Database likewise has its own networking lifecycle and is not the service to which this Network Anchor-specific private-zone replication setting applies.
Therefore, the database service required to expose the specified option is Oracle Base Database Service .

質問 # 49
You are provisioning a new Oracle Autonomous AI Database Serverless instance in the Azure Portal and must configure the database credentials under the Configuration tab. What is the database administrator username for this instance, and how is it configured in the creation wizard?
正解：D
解説：
When Oracle Autonomous AI Database Serverless is provisioned through Oracle AI Database@Azure, the administrative database account follows the standard Autonomous Database account model. The Azure creation workflow exposes the Username field as read-only and set to ADMIN .
The administrator therefore supplies the password for the predefined ADMIN account but does not choose or rename the account during database creation. Oracle currently specifies password requirements separately, including minimum and maximum length and character-composition requirements.
The account is not derived from the Microsoft Entra ID identity that deploys the Azure resource. Azure RBAC and Microsoft Entra authentication govern access to the Azure resource-management plane, whereas the ADMIN credential is a database-level account. Similarly, SYS is not presented as the configurable provisioning username for Autonomous AI Database Serverless, and the username is not generated from subscription metadata.
This separation between Azure control-plane identity and Oracle database credentials is architecturally important when designing authentication and administrative access.
Therefore, the correct answer is A .

質問 # 50
Which core Oracle Database technology is utilized under the hood to deliver localized node-level high availability in the MAA Silver tier for Exadata Database Service on Dedicated Infrastructure in Oracle AI Database@Azure?
正解：C
解説：
Oracle Maximum Availability Architecture Silver adds Oracle Real Application Clusters (RAC) to the MAA Bronze foundation. RAC provides active-active database clustering across multiple database-server nodes while all instances access the same underlying database storage.
For Exadata Database Service on Dedicated Infrastructure, RAC supplies localized protection against database-instance and database-server failure. If one RAC instance or compute node fails, services and connections can relocate to surviving instances that are already running. RAC also materially reduces or eliminates database downtime for many planned maintenance operations.
Oracle Active Data Guard addresses a different availability layer: it maintains a physically separate standby database and is primarily used for site, availability-zone, or regional disaster recovery. Oracle GoldenGate performs logical data replication and integration, while Oracle Sharding distributes data across independent database shards for scale and fault isolation.
Oracle's current MAA documentation explicitly identifies RAC as the technology introduced at the Silver tier and recommends Exadata as the optimized RAC platform.
Therefore, B is correct.

質問 # 51
Which two resources can be dynamically associated with an Oracle AI Database@Azure delegated subnet in Azure to manage traffic routing and filtering? (Choose two.)
正解：C、D
解説：
An Oracle AI Database@Azure delegated subnet remains part of the customer's Azure VNet and can use supported Azure networking controls. Two fundamental controls are Network Security Groups (NSGs) and Azure route tables containing User-Defined Routes .
An NSG performs traffic filtering by applying inbound and outbound security rules based on criteria such as source, destination, protocol, and port. This allows organizations to enforce database-access policies at the Azure network layer. Route tables provide forwarding control, allowing traffic to be directed through Azure Firewall, an NVA, a virtual network gateway, or other supported next-hop architecture.
Oracle's delegated-subnet design documentation explicitly states that because the delegated subnet belongs to the customer's VNet, it can leverage Azure networking capabilities including NSGs and routing tables . This enables private application-to-database communication while retaining enterprise routing and security controls.
Azure Load Balancer backend pools and Application Gateway ingress controllers are application/load- balancing constructs and are not the two subnet-associated controls identified for this Oracle database networking requirement.
