質問 # 31
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?
正解：A
解説：
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 .

質問 # 32
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?
正解：D
解説：
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.

質問 # 33
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 # 34
Which two database services are officially supported and available for deployment on optimized hardware in Oracle AI Database@Azure? (Choose two.)
正解：A、D
解説：
Among the choices presented, Oracle Exadata Database Service on Dedicated Infrastructure and Oracle Autonomous AI Database are both native Oracle AI Database@Azure database services designed to run on Oracle-optimized database infrastructure located inside Azure data centers. Exadata Database Service provides customer-managed Oracle Database environments on purpose-built Exadata hardware, with RAC, Data Guard, elastic compute, and high-performance storage capabilities. Autonomous AI Database provides a fully managed database model in which Oracle automates provisioning, patching, tuning, backup operations, and resource scaling.
Oracle's current service portfolio has expanded further and now also includes Exadata Database Service on Exascale Infrastructure, Base Database Service, Autonomous AI Database on Dedicated Exadata Infrastructure, GoldenGate, and Autonomous Recovery Service. However, those services are not alternatives in this question. Oracle NoSQL Database Cloud Service is not one of the listed Oracle AI Database@Azure database offerings, while a generic Oracle Database Standard Edition VM running on Azure IaaS is not equivalent to a native Oracle AI Database@Azure service.
Therefore, B and C are correct. Study Guide reference: Provision and operate Oracle AI Database@Azure Resources - supported database services and optimized Oracle infrastructure.
質問 # 35
Which two DNS endpoints can be optionally enabled when provisioning a Network Anchor for Oracle AI Database@Azure? (Choose two.)
正解：B、D
解説：
Oracle AI Database@Azure Network Anchors support DNS integration between Azure-side applications and OCI-side database networking. The two endpoint constructs used by Oracle DNS are the DNS forwarding endpoint and DNS listening endpoint .
For inbound DNS resolution from OCI toward Azure, Oracle's Network Control Plane can create a forwarding DNS endpoint and configure forwarding rules so OCI-hosted resources can forward queries toward the Azure DNS environment. Conversely, outbound resolution from Azure toward Oracle resources relies on an OCI listening DNS endpoint. The listening endpoint receives DNS requests and enables Azure or connected on- premises systems to resolve Oracle AI Database@Azure names.
The terminology is important. Oracle explicitly uses listening and forwarding endpoint constructs. "DNS replication endpoint" is not the endpoint name used for private-zone synchronization, and "DNS peering endpoint" is not an Oracle Network Anchor endpoint type. DNS-record synchronization is a separate behavior from the endpoint resource itself.
Consequently, the correct selections are A and D .
