70. Frage
Your team is preparing to migrate an on-premises database to Autonomous Database Serverless on Oracle Database@Azure using ZDM and wants to ensure that the Data Pump dump files are staged entirely within the Microsoft Azure subscription. Which storage option should you configure in the ZDM response file as the data transfer medium to meet this requirement?
Antwort: A
Begründung:
The correct staging medium is an Azure Files NFS share . Oracle's ZDM documentation for Autonomous AI Database Serverless on Oracle Database@Azure explicitly supports Azure Files as an NFS file-share source for Data Pump migration staging.
In the logical migration workflow, the NFS share is made accessible to the source database and attached to the Autonomous AI Database target. Data Pump export files can therefore be written to and read from the shared location without being staged in OCI storage. Oracle specifically documents mounting Azure Files NFSv4.x and exposing the path through a database directory for Data Pump operations.
OCI Object Storage and OCI File Storage would place the staging data within OCI, violating the explicit requirement that dump files remain in the Microsoft Azure subscription. Azure Blob Storage can be accessed by Autonomous Database through DBMS_CLOUD for supported object-storage workflows, but the standard ZDM NFS-based Data Pump staging mechanism described in this question uses a mounted filesystem rather than a direct Blob REST API.
Therefore, C is correct.

71. Frage
Which two DNS endpoints can be optionally enabled when provisioning a Network Anchor for Oracle AI Database@Azure? (Choose two.)
Antwort: B,D
Begründung:
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 .

72. Frage
A financial corporation is planning to deploy Oracle AI Database@Azure to run transactional workloads that are governed by strict federal regulations regarding security controls, management processes, and data sovereignty. The compliance officer is concerned that migrating databases to physical infrastructure located in Azure data centers (the Child Site) will introduce compliance discrepancies compared to workloads running natively in Oracle Cloud Infrastructure regional data centers. As the multicloud solutions architect, you need to explain how the architectural relationship between the OCI Parent Site and the Azure-resident Child Site resolves these compliance concerns. Which of the following statements represents the official OCI architectural design that you should present to the compliance officer? Choose ONE.
Antwort: B
Begründung:
Oracle defines the Azure-resident Child Site as an extension of the associated OCI Parent Site rather than as an independently governed Azure database platform. The Oracle database infrastructure is physically deployed in an isolated area of an Azure data center, while Oracle retains operation and management responsibility for the Oracle hardware and database service stack. The Child Site is paired with a geographically corresponding OCI region containing the Oracle AI Database@Azure control plane.
The critical architectural principle is that the Child Site maintains the same security, management, resiliency, and performance profile as an OCI region. This design minimizes compliance discontinuities when regulated database workloads are placed physically in Azure. OCI control-plane services continue providing lifecycle management, availability engineering, security controls, and operational governance. Parent and Child Sites are also positioned geographically to address data-sovereignty, residency, and latency requirements.
Therefore, the architecture does not transfer database security governance wholesale to Azure Security Center, nor does it depend on customer on-premises gateways for policy synchronization. Oracle explicitly describes the Child Site as an extension of the Parent Site. Study Guide reference: Oracle AI Database@Azure Architecture and Onboarding - Parent Site, Child Site, control-plane architecture, security and resiliency.
73. Frage
A mid-size retailer wants to move a moderately sized seasonal transactional workload to Oracle AI Database@Azure. They want to avoid provisioning dedicated database and storage servers, want to start with a small committed footprint and elastically scale ECPUs and storage online as holiday sales volume grows, and want the ability to create instant, space-efficient thin clones of production for their developers. As the architect, you must select the Oracle AI Database@Azure deployment option that meets all of these needs.
Choose ONE.
Antwort: B
Begründung:
Oracle Exadata Database Service on Exascale Infrastructure precisely matches the scenario. Exascale uses Oracle-managed, multitenant physical database-server infrastructure, allowing customers to provision relatively small VM Clusters rather than committing to dedicated Exadata database and storage servers.
A VM Cluster can begin at 8 ECPUs per VM and scale its compute allocation in 4-ECPU increments.
Exascale storage is also elastic and can be expanded without requiring customers to add or manage physical Exadata Storage Servers.
A distinctive Exascale feature is redirect-on-write thin cloning . Oracle documents the ability to create space-efficient PDB clones in which unchanged blocks remain shared between the parent and clone. This makes development and test copies fast to provision and economical in storage consumption.
Dedicated Infrastructure contradicts the requirement to avoid dedicated server capacity. Base Database Service does not offer the same Exascale thin-clone architecture, while Autonomous Serverless represents a different autonomous operating model.
Therefore, B is correct.

74. Frage
What is the subnet requirement for configuring an OCI Hub VCN to enable transit routing for Active Data Guard traffic between Oracle Database@Azure regions?
Antwort: B
Begründung:
Oracle's reference architecture for multi-region Oracle Database@Azure disaster recovery explicitly states that no subnet is required in the Hub VCN to enable transit routing .
The Hub VCN serves primarily as a routing construct connecting gateways and route-table attachments.
DRGs, Local Peering Gateways, Remote Peering Connections, and VCN route tables provide the required network forwarding between the Oracle Database@Azure Child Site VCNs and remote regions. Because the hub does not need to host compute instances or network virtual appliances for this gateway-based transit model, it does not require a workload subnet.
This has an additional design benefit: the hub VCN can use a comparatively small CIDR range because there is no requirement to reserve substantial address space for servers or VNICs.
A public subnet and Internet Gateway are unnecessary because Data Guard traffic should traverse private cloud networking. Likewise, dedicated /24 transit-appliance subnets or per-availability-domain private subnets are not mandatory for the gateway-based topology.
Therefore, D is correct.
