NEW QUESTION # 60
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?
Answer: A
Explanation:
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 .

NEW QUESTION # 61
You have selected the custom FQDN option and specified your own domain during Exadata VM Cluster provisioning in Oracle AI Database@Azure. What must you do afterward to ensure name resolution works from your production DNS zone?
Answer: A
Explanation:
When an architect selects Custom DNS/FQDN , the database cluster is created using the organization's chosen DNS namespace instead of relying exclusively on Oracle's default automatically managed oraclevcn.
com private-zone behavior.
The important operational requirement is that application clients must be able to resolve the Exadata cluster's connection endpoints. That includes the Single Client Access Name (SCAN) and the relevant Virtual IP (VIP) records. Because the organization controls the custom production DNS namespace, those records must be represented in that DNS environment so client applications can resolve the cluster correctly.
Disabling OCI private DNS would damage internal Oracle name resolution rather than extending resolution to the enterprise DNS system. Waiting for Oracle to create a default oraclevcn.com zone does not satisfy a custom-domain deployment, and reverting to default DNS would defeat the original custom-FQDN design.
Therefore, the required action is to manually duplicate or publish the SCAN and VIP records in the production DNS zone .

/VIP records and enterprise DNS integration.
NEW QUESTION # 62
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?
Answer: C
Explanation:
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.

NEW QUESTION # 63
If a customer does not configure a customer-managed key, where does Oracle AI Database@Azure store the default TDE master encryption key for an Exadata database?
Answer: C
Explanation:
The default encryption-key model for an Exadata database on Oracle AI Database@Azure is Oracle- Managed Keys (OMK) . Under this model, Oracle automatically generates the Transparent Data Encryption master encryption key and stores it in an Oracle Wallet secured within the database environment.
Oracle manages the complete lifecycle of this default key, including generation, secure storage, rotation, backup, and restoration. No additional customer-side key-management infrastructure is required.
OCI Vault, Oracle Key Vault, and Azure Key Vault represent customer-managed key alternatives. When an organization selects one of these mechanisms, the TDE master key is managed outside the local Oracle Wallet, enabling centralized customer control, auditing, rotation policy, and separation of duties. However, none is the default unless the customer explicitly configures a customer-managed key architecture.
Oracle's current security documentation explicitly identifies Oracle Wallet as the default encryption-key setting for Exadata Database Service on Oracle AI Database@Azure.
Therefore, C. Oracle Wallet is correct.

NEW QUESTION # 64
You are planning to migrate an on-premises Oracle Database to an Autonomous Database Serverless target on Oracle Database@Azure. Which migration workflow families are supported by Zero Downtime Migration (ZDM) to accomplish this task?
Answer: B
Explanation:
For an Autonomous AI Database Serverless target, Oracle Zero Downtime Migration supports Logical Online and Logical Offline migration workflows.
Logical migration is necessary because Autonomous AI Database Serverless abstracts the underlying physical database infrastructure and does not expose the file-system and database-host control required for a conventional physical RMAN/Data Guard migration. ZDM therefore operates through logical database migration technologies.
Logical Offline uses Oracle Data Pump export and import to instantiate the target. Logical Online adds Oracle GoldenGate to the workflow so changes occurring on the source after the initial data load are captured and applied to the target until final cutover, greatly reducing application downtime.
Oracle's Oracle Database@Azure migration documentation explicitly lists these two workflows for migration to Autonomous Database Serverless. Physical Online and Physical Offline workflows apply to supported customer-managed Oracle database targets, such as Exadata Database Service, rather than Autonomous Serverless.
Therefore, A is correct.
