問題 #95
What is the minimum storage capacity that must be allocated when creating a new Exadata Database Storage Vault for Exascale Infrastructure in Oracle AI Database@Azure?
答案：D
解題說明：
Oracle Exadata Database Service on Exascale Infrastructure separates database storage into Exascale Database Storage Vaults . Oracle documents the minimum billed Database Storage Vault capacity as 300 GB per VM Cluster .
The minimum is composed of storage required for system use and the first database. Oracle's current Exascale capacity table allocates 50 GB for system-related usage, including images stored in ACFS, and 250 GB for database use when provisioning the first database. Together, these produce the 300 GB minimum vault capacity.
This value must not be confused with VM file-system storage. Current Exascale guidance specifies a separate minimum VM file-system capacity that varies by database version-for example, 220 GB for a 26ai VM configuration. That explains why 220 GB appears plausible but is incorrect for the Database Storage Vault asked about here.
The vault can subsequently be scaled substantially beyond the minimum; Oracle documents VM Cluster Exascale Vault storage scaling up to 100 TB.
Therefore, the correct answer is D. 300 GB .

問題 #96
You have completed the purchase of an Oracle AI Database@Azure Private Offer through the Microsoft Azure Marketplace. What is the next required architectural step in the onboarding workflow before you can create your Exadata infrastructure?
答案：B
解題說明：
Purchasing the Azure Marketplace offer establishes the commercial entitlement, but it does not by itself establish the technical relationship between the customer's Azure environment and OCI tenancy. Oracle's onboarding sequence requires multicloud linking after purchase.
During this step, the selected Azure subscription is linked with an Oracle Cloud Infrastructure tenancy. That association enables the service to establish the required cross-cloud resource, subscription, governance, and management relationships. Oracle's current overview explicitly states that after the purchase is complete, the Azure subscription is linked with an OCI tenancy; this process is called multicloud linking.
Only after onboarding and linking are completed does the administrator move into resource provisioning. At that stage, the environment can be prepared with the VNet, delegated subnet, Exadata infrastructure, VM Cluster, Autonomous AI Database, or applicable anchor constructs. Therefore, creating networking components before completing the required subscription/tenancy association reverses the documented onboarding sequence.
DNS-specific configuration is also part of networking rather than the immediate post-purchase account- linking requirement.

問題 #97
Where is a long-term retention backup in the Oracle Database Autonomous Recovery Service automatically moved after its first 24 hours of storage?
答案：C
解題說明：
Oracle Database Autonomous Recovery Service supports Long-Term Retention (LTR) backups for organizations that need to preserve full database backups for compliance, regulatory, legal, or business requirements. The correct destination is the OCI Object Storage Infrequent Access tier .
The question source specifies that the LTR backup initially remains in the standard storage tier and transitions after the first 24 hours to Infrequent Access storage for the remainder of its retention period. Oracle's Recovery Service documentation independently confirms that long-term retention backups are stored in the Object Storage Infrequent Access tier and can be retained for periods extending up to ten years.
The Infrequent Access tier is appropriate because LTR backups are retained for extended periods but are generally restored less frequently than operational backups. Archive Storage is not the managed destination used by Recovery Service for this workflow. Azure Archive Blob Storage is likewise not the Oracle-managed OCI storage tier identified for these backups, and there is no "OCI Legacy Backup" storage tier.
Therefore, D is correct.

問題 #98
Which of the following is NOT one of the documented supported network topologies for Oracle AI Database@Azure?
答案：B
解題說明：
Azure Front Door single-endpoint routing is not a documented Oracle AI Database@Azure database connectivity topology.
Azure Front Door is primarily a global Layer-7 HTTP/HTTPS application-delivery, acceleration, and load- balancing service. It is designed for web applications and public-facing application endpoints rather than private SQL*Net/database connectivity into an Oracle AI Database@Azure delegated subnet.
Oracle's documented networking patterns instead center on Azure VNets and private routing. These include local/same-region VNet connectivity, VNet peering, Hub-and-Spoke VNet peering, cross-region connectivity, and hybrid on-premises Hub-and-Spoke architectures. Oracle also documents enterprise connectivity patterns involving Azure Virtual WAN.
Hub-and-Spoke is particularly important where centralized firewalls or NVAs must inspect database-bound traffic, while local VNet/VNet peering is useful for direct application-to-database private communication where minimizing network latency is the priority.
Because Azure Front Door does not provide the required private database networking architecture and is absent from Oracle's supported topology set, C is the correct answer.
Study Guide reference: Configure Oracle AI Database@Azure Networking - supported VNet, peering, Hub-and-Spoke and enterprise connectivity topologies.
問題 #99
You are configuring a cross-region disaster recovery topology for an Exadata Database Service deployment on Oracle Database@Azure and need to connect the primary database VCN to the standby database VCN.
What OCI network resource limitation necessitates the creation of a second VCN acting as a Hub VCN to establish this regional peering link?
答案：C
解題說明：
Oracle's cross-region Oracle Database@Azure reference architecture requires an additional Hub VCN because each OCI VCN can be attached to only one Dynamic Routing Gateway (DRG) at a time.
The Oracle-managed database VCN associated with an Exadata VM Cluster already uses a DRG as part of the Oracle Database@Azure network architecture. Cross-region VCN peering also requires DRG-based remote peering. Because a second DRG cannot simply be attached to the existing database VCN, Oracle introduces a separate Hub VCN with its own DRG. The database VCN is locally connected to the Hub VCN, and the Hub DRGs establish the cross-region remote peering connection.
OCI documentation independently confirms that one VCN can attach to only one DRG, whereas a single DRG can support many VCN attachments. A VCN can also have multiple Local Peering Gateways, so option B is technically incorrect.
The limitation is therefore architectural rather than a restriction caused by Azure subnet delegation or tenancy boundaries.
