問題 #26
Which statement best describes the purpose of OCI Vault in the context of Oracle AI Database@Azure?
答案：A
解題說明：
OCI Vault is Oracle Cloud Infrastructure's centralized service for managing encryption keys and secrets. In Oracle AI Database@Azure, it can participate in customer-managed key architectures for Oracle Transparent Data Encryption.
TDE encrypts Oracle database data at rest using master encryption keys. Oracle AI Database@Azure supports Oracle-managed keys stored in an Oracle Wallet as the default model and several customer-managed key stores, including OCI Vault, Oracle Key Vault, and Azure Key Vault. Using OCI Vault allows organizations to manage cryptographic key lifecycle operations-including controlled creation, rotation, access policy, and auditing-outside the database itself.
Vault and identity management should not be confused. Microsoft Entra ID and OCI IAM Identity Domains implement identity federation and user authentication; OCI Vault does not function as an identity provider.
Likewise, it is unrelated to content delivery or application/network connectivity. Delegated subnets remain mandatory Azure networking constructs regardless of the selected encryption-key architecture.
Therefore, the correct description is A .

問題 #27
What are the core ECPU scaling increments required when configuring the enabled ECPU count per virtual machine for an Exadata VM Cluster on Exascale Infrastructure?
答案：B
解題說明：
Oracle Exadata Database Service on Exascale Infrastructure uses the Elastic Compute Processing Unit (ECPU) model for allocating database-server processing capacity. Oracle's Exascale technical architecture specifies that a VM requires at least eight enabled ECPUs for initial VM Cluster provisioning and that vertical compute scaling is performed in increments of four ECPUs .
This model provides substantially finer-grained scaling than traditional fixed Exadata infrastructure shapes while maintaining predictable resource allocation across the underlying Exascale compute pool.
Administrators can increase enabled ECPUs as workload demand grows, and Exascale also supports reserved ECPU concepts that allow capacity to be physically reserved for future growth. The distinction between enabled and reserved capacity is operationally important: enabled ECPUs are active compute resources used by the VM, whereas reserved capacity can facilitate future scale-up.
An increment of eight would unnecessarily double the required scaling step; one- or two-ECPU increments are not the documented unit for Exadata VM scaling on Exascale Infrastructure. The correct granularity is therefore four ECPUs .

問題 #28
You have selected the custom FQDN option and specified your own domain during Exadata VM Cluster provisioning in Oracle AI Database@Azure. What must you do afterward to ensure name resolution works from your production DNS zone?
答案：D
解題說明：
When an architect selects Custom DNS/FQDN , the database cluster is created using the organization's chosen DNS namespace instead of relying exclusively on Oracle's default automatically managed oraclevcn.
com private-zone behavior.
The important operational requirement is that application clients must be able to resolve the Exadata cluster's connection endpoints. That includes the Single Client Access Name (SCAN) and the relevant Virtual IP (VIP) records. Because the organization controls the custom production DNS namespace, those records must be represented in that DNS environment so client applications can resolve the cluster correctly.
Disabling OCI private DNS would damage internal Oracle name resolution rather than extending resolution to the enterprise DNS system. Waiting for Oracle to create a default oraclevcn.com zone does not satisfy a custom-domain deployment, and reverting to default DNS would defeat the original custom-FQDN design.
Therefore, the required action is to manually duplicate or publish the SCAN and VIP records in the production DNS zone .

/VIP records and enterprise DNS integration.
問題 #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.
答案：D
解題說明：
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.

問題 #30
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.)
答案：B,C
解題說明：
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.
