72. Frage
Which two are documented supported network topologies for connecting applications to Oracle AI Database@Azure? (Choose two.)
Antwort: C,D
Begründung:
Oracle documents multiple Azure network patterns for application connectivity to Oracle AI Database@Azure, including VNet peering and Hub-and-Spoke VNet peering .
VNet peering enables application workloads in one Azure VNet to communicate privately with Oracle database resources exposed through a delegated subnet in another VNet. This is appropriate when relatively direct, low-latency communication is required.
A Hub-and-Spoke design introduces a central hub containing shared connectivity and security services, such as Azure Firewall, a Network Virtual Appliance, ExpressRoute gateway, or VPN gateway. Application and database VNets connect as spokes or workload/data networks, allowing centralized inspection and hybrid connectivity.
Oracle's documented topology set also includes local VNet, global connectivity, on-premises Hub-and-Spoke, and related enterprise designs. A point-to-site VPN client model is not identified as the standard application topology requested here. More fundamentally, an Oracle AI Database@Azure deployment cannot exist without an Azure VNet and delegated networking.
Therefore, the correct selections are B and C .

73. Frage
What is the minimum number of ECPUs required per VM to provision a VM cluster on Oracle Exadata Database Service on Exascale Infrastructure?
Antwort: A
Begründung:
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 .

74. Frage
Which two are documented supported network topologies for connecting applications to Oracle AI Database@Azure? (Choose two.)
Antwort: C,D
75. Frage
By default, how many delegated subnets can Oracle AI Database@Azure use before a service limit increase must be requested?
Antwort: C
Begründung:
Oracle AI Database@Azure has a default regional service limit of five delegated subnets . Once a deployment requires more than five delegated subnet links in a region, the customer must request a service- limit increase.
This aggregate regional limit must not be confused with the separate VNet design rule. An individual Azure VNet can contain a maximum of one delegated subnet for Oracle AI Database@Azure, but an organization can have several VNets and therefore several delegated subnets across the same region up to the default service limit.
Oracle identifies the relevant service-limit metadata as:
Service: Multicloud
Resource: Delegated Subnet Multicloud Links
Limit name: azure-delegated-subnet-count
The limit operates at regional scope. Therefore, creating additional peerings or Route Servers does not bypass it; the correct approach is to request additional service capacity through Oracle's service-limit process.
Values of 1, 3, and 10 do not represent the default regional limit.
Therefore, A. 5 is correct.
Study Guide reference: Configure Oracle AI Database@Azure Networking - delegated subnet quotas and service-limit increases.
76. Frage
Which two network routing capabilities or controls are supported when configuring User Defined Routes (UDR) within the delegated subnets of Oracle AI Database@Azure? (Choose two.)
Antwort: B,C
Begründung:
Azure User-Defined Routes provide explicit Layer-3 forwarding control for traffic entering or leaving an Oracle AI Database@Azure delegated subnet. Oracle's documented network topologies use UDRs to direct application, on-premises, and database traffic through prescribed next hops such as an Azure Firewall or Network Virtual Appliance. This enables architects to construct custom network routing paths between on- premises systems and Exadata databases and exercise granular routing control across hybrid infrastructure .
In a Hub-and-Spoke deployment, for example, UDRs on application spokes can force database-bound traffic through the hub firewall, while corresponding routes on the Oracle AI Database@Azure spoke provide a symmetric return path. This is an architectural routing control, not a dynamic-routing protocol. ExpressRoute path selection is governed by BGP and ExpressRoute configuration rather than by a UDR automatically choosing between circuits.
Likewise, UDRs do not override Oracle-managed control-plane connectivity or scheduled lifecycle- management routes. Those functions remain under the service architecture.
Therefore, A and C are the supported routing capabilities. Study Guide reference: Configure Oracle AI Database@Azure Networking - UDRs, delegated subnets, hybrid connectivity, Hub-and-Spoke routing.
