質問 # 25
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：B
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 # 26
Your database administrator enabled a backup retention lock on an Autonomous AI Database in Oracle AI Database@Azure but now needs to reduce the retention period. What must you do to disable this retention lock or alter the retention period?
正解：A
解説：
Backup Retention Lock is a protection mechanism intended to prevent administrators or compromised credentials from prematurely reducing the recoverability window of Autonomous AI Database backups. Once the lock is established, normal administrative interfaces cannot simply disable it or reduce the protected backup-retention period.
Oracle's Autonomous AI Database documentation explicitly states that after the backup retention lock has been set, the option cannot be disabled or the retention period changed through ordinary database administration. To disable the lock or modify the locked retention setting, the administrator must file a Service Request with Oracle Cloud Support .
This design provides an administrative separation between ordinary database management and an action that could materially weaken backup protection. Changing an Azure Key Vault key has no relationship to the retention-policy lock. An SQL ALTER DATABASE command cannot override a service-level backup governance control, and the Azure Portal does not expose a supported bypass to reduce the locked period.
Accordingly, A is the only supported escalation path in the choices.

質問 # 27
Which protocol is used to configure identity federation between Microsoft Entra ID and an OCI IAM identity domain for Oracle AI Database@Azure?
正解：A
解説：
Oracle's documented federation procedure between Microsoft Entra ID and an OCI IAM Identity Domain uses Security Assertion Markup Language (SAML) , specifically SAML 2.0.
During configuration, an Oracle Cloud Infrastructure Console enterprise application is configured in Microsoft Entra ID. The administrator selects SAML as the single sign-on method, exchanges SAML metadata between Microsoft Entra ID and the OCI Identity Domain, configures identity attributes and claims, and establishes Microsoft Entra ID as the identity provider for OCI.
SAML allows an administrator to authenticate through the enterprise Microsoft identity environment and obtain federated access to OCI without maintaining a separate password specifically for the OCI Console.
Kerberos is primarily a ticket-based authentication protocol traditionally associated with Active Directory and internal network authentication. RADIUS is commonly used for network access authentication and accounting. OAuth 2.0 Client Credentials is designed for service-to-service authorization rather than interactive federated user SSO.
Therefore, D. SAML is the correct protocol.

質問 # 28
What is the minimum number of ECPUs required per VM to provision a VM cluster on Oracle Exadata Database Service on Exascale Infrastructure?
正解：C
解説：
Oracle Exadata Database Service on Exascale Infrastructure uses the Elastic Compute Processing Unit (ECPU) resource model. During initial VM Cluster provisioning, Oracle requires a minimum of 8 ECPUs enabled per VM .
The distinction between the initial minimum and subsequent scaling increments is important. After the VM Cluster exists, enabled compute capacity is adjusted in increments of 4 ECPUs . Therefore, 4 ECPUs represents the scaling granularity, not the minimum provisionable starting configuration. Oracle also allows enabled ECPUs to be reduced to zero after provisioning when administrators need to temporarily shut down the VMs and suspend enabled-ECPU usage billing, but zero cannot be used as the initial active configuration.
Current Oracle documentation defines the supported total ECPU allocation per VM within the applicable Exascale service limits and explicitly states that the provisioned value must be a multiple of four.
Consequently, neither 1 nor 4 meets the initial provisioning baseline, while 16 is valid but exceeds the minimum. The correct answer is A. 8 ECPUs .

質問 # 29
An architect is designing a cross-region disaster recovery (DR) topology for Oracle Exadata Database Service on Dedicated Infrastructure in Oracle AI Database@Azure. The Active site virtual network is named odb- multicloud-production-vnet with a delegated subnet named odb-multicloud-production-subnet. The DR site virtual network is named odb-multicloud-production-DR-vnet with a delegated subnet named odb-multicloud- production-DR-subnet. When configuring both clusters to use the default managed DNS, the architect discovers that both sites automatically generate the identical host domain and DNS private zone name of ociodbmulticlo.ociodbmulticlo.oraclevcn.com, preventing unique DNS conditional forwarding from on- premises servers. To resolve this naming collision while continuing to use default managed DNS, what must the architect do? Choose ONE.
正解：B
解説：
Under the default managed-DNS model, Oracle derives the private Oracle domain from normalized VNet and delegated-subnet naming components. In the source scenario, the production and DR resource names share the same leading characters, causing both sites to derive the same oraclevcn.com private DNS namespace.
The practical resolution is therefore to alter the naming inputs before deployment so the generated DNS labels are unique. The uploaded question set specifies that the relevant generated tokens use the first 11 alphanumeric characters , so either the DR VNet or delegated subnet must be renamed such that the derived prefix differs from the active environment.
The Host Domain Name field associated with default managed DNS is system-generated rather than freely editable. Adding another DNS resolver does not eliminate the underlying duplicate private-zone namespace, and DNS views cannot reliably correct a collision created at resource provisioning.
Therefore, D resolves the root cause while retaining Oracle-managed DNS.
