102. Frage
Which two statements are true about the delegated subnet used by Oracle AI Database@Azure? (Choose two.)
Antwort: C,D
Begründung:
Oracle's current network guidance defines two important delegated-subnet constraints. First, each Azure VNet can contain a maximum of one Oracle AI Database@Azure delegated subnet . Second, a single delegated subnet can support multiple VM Clusters , provided IP capacity and availability-zone constraints are satisfied.
Oracle clarifies that multiple VM Clusters from the same Exadata Infrastructure can share a delegated subnet.
VM Clusters belonging to different Exadata Infrastructure resources can also share one when those infrastructure resources reside in the same availability zone .
However, Exadata Infrastructure resources located in different availability zones cannot share the same delegated subnet. Oracle identifies such a configuration as producing a suboptimal network path and requires separate delegated networking for cross-zone deployments.
The delegated subnet also uses Azure private address space; it is not required to use-and should not be designed around-a public IPv4 CIDR range.
Therefore, A and C are correct.

103. Frage
A financial services company is deploying Oracle Exadata Database Service on Dedicated Infrastructure on Oracle AI Database@Azure. Their security team mandates that database traffic never traverse the public internet, and that the Azure VNet hosting the delegated subnet also connect to three separate application-tier spoke VNets in the same region. Additionally, all inter-VNet traffic must pass through a centralized network virtual appliance for inspection before reaching the delegated subnet. As the architect, you must choose the network topology that satisfies both the multi-VNet connectivity and the centralized inspection requirement.
Choose ONE.
Antwort: A
Begründung:
The intended topology is Hub-and-Spoke with centralized NVA inspection , making C the correct choice among the available answers. This architecture permits multiple application VNets to communicate privately with the Oracle database while routing inter-VNet traffic through a central firewall or Network Virtual Appliance rather than the public internet.
There is an architectural wording issue worth correcting precisely. Oracle's published reference topology normally places the Azure Firewall/NVA in the Hub VNet while Oracle Database@Azure resides in a separate Data VNet containing the delegated client subnet . Application workloads reside in spoke VNets.
The hub then provides centralized routing and inspection between the application spokes and the data VNet.
Therefore, the essential principle embodied by C- Hub-and-Spoke plus centralized NVA inspection -is correct, although the phrase "delegated subnet in the hub VNet" is not how Oracle's canonical diagram lays out the components.
Direct local peering would bypass centralized inspection, while direct Virtual WAN spoke-to-spoke communication violates the same requirement. Data Guard concerns DR, not application traffic inspection.
104. Frage
You have provisioned an Exadata VM Cluster on Exascale Infrastructure with 8 ECPUs per VM and a 300 GB Exascale Database Storage Vault. Your workload has grown and additional compute capacity is now required. What should you do?
Antwort: C
Begründung:
Elastic resource allocation is a fundamental design characteristic of Oracle Exadata Database Service on Exascale Infrastructure . A VM requires a minimum of 8 enabled ECPUs at initial provisioning, but its compute allocation can subsequently be increased in 4-ECPU increments .
Oracle's Exascale architecture draws compute resources from Oracle-managed shared infrastructure rather than requiring the customer to purchase or provision dedicated database servers. This permits a customer to start with a relatively small footprint and increase capacity as workload requirements develop.
The workload therefore does not need to be migrated to Dedicated Infrastructure merely because additional processing power is required. Nor is it necessary to destroy and rebuild the VM Cluster or create an entirely new Exadata Infrastructure resource. Exascale is specifically intended to avoid those fixed-capacity operational patterns.
Oracle additionally supports online scaling of Exascale storage independently through the associated Database Storage Vault, reinforcing the service's elastic consumption model.
Therefore, D is correct.

105. Frage
Your organization runs its critical billing workloads on Oracle Exadata Database Service on Dedicated Infrastructure within Oracle AI Database@Azure. The security and operations teams require a unified dashboard in the Azure Portal to monitor Exadata VM cluster lifecycle management actions, database events, Exadata infrastructure health, and Data Guard replication logs. The solution must allow administrators to write Kusto Query Language (KQL) queries to correlate these logs with Azure application VM logs in real time without deploying custom agents inside the database VMs. As the multicloud architect, which configuration should you recommend to meet these requirements? Choose ONE.
Antwort: C
Begründung:
The native architecture is to configure Azure Monitor diagnostic settings on the Oracle Exadata resources and route the selected log categories into an Azure Log Analytics workspace .
Oracle AI Database@Azure exposes relevant Exadata lifecycle and operational events through Azure diagnostic settings without requiring agents to be installed on Oracle-managed Exadata nodes. Once the telemetry reaches Log Analytics, administrators can query it using Kusto Query Language (KQL) and correlate the Oracle resource events with telemetry generated by Azure application infrastructure.
This architecture satisfies the requirement for centralized Azure-side observability while preserving the managed-service boundary of Exadata. It also integrates naturally with Azure dashboards, alerting, Microsoft Sentinel, and other Azure Monitor capabilities.
Using OCI Object Storage would introduce an unnecessary cross-platform telemetry pipeline. Oracle Enterprise Manager remains useful in broader Oracle management scenarios but is not required for this native Azure integration. Installing Azure Monitor Agent directly on Oracle-managed Exadata infrastructure is neither necessary nor the documented implementation pattern.
Therefore, A provides the supported integrated monitoring architecture.

106. Frage
What is the default CIDR block range used to create the backup subnet for an Exadata VM Cluster in Oracle AI Database@Azure if the field is left blank during provisioning?
Antwort: C
Begründung:
During Exadata VM Cluster provisioning, the administrator selects the client delegated subnet and can explicitly provide a CIDR range for the Exadata backup network. If no backup-subnet CIDR is supplied, Oracle automatically uses the documented default of 192.168.252.0/22 .
The backup subnet serves Oracle database backup-network requirements and is architecturally distinct from the Azure delegated client subnet. Oracle's deployment-planning guidance emphasizes that the default backup CIDR is not part of the Azure VNet CIDR allocation. Nevertheless, address planning remains important. In disaster-recovery designs involving multiple Exadata deployments-especially cross-availability-zone or cross-region configurations-the administrator should explicitly choose non-overlapping backup CIDR blocks so that replication, routing, and backup traffic do not encounter conflicting address ranges.
Option B uses the correct network prefix but an incorrect /24 mask. Options A and D use different base networks and therefore do not match the Oracle provisioning default.
Accordingly, the correct response is C: 192.168.252.0/22 .
