NEW QUESTION # 64
Your database administrator enabled a backup retention lock on an Autonomous AI Database in Oracle AI Database@Azure but now needs to reduce the retention period. What must you do to disable this retention lock or alter the retention period?
Answer: C
Explanation:
Backup Retention Lock is a protection mechanism intended to prevent administrators or compromised credentials from prematurely reducing the recoverability window of Autonomous AI Database backups. Once the lock is established, normal administrative interfaces cannot simply disable it or reduce the protected backup-retention period.
Oracle's Autonomous AI Database documentation explicitly states that after the backup retention lock has been set, the option cannot be disabled or the retention period changed through ordinary database administration. To disable the lock or modify the locked retention setting, the administrator must file a Service Request with Oracle Cloud Support .
This design provides an administrative separation between ordinary database management and an action that could materially weaken backup protection. Changing an Azure Key Vault key has no relationship to the retention-policy lock. An SQL ALTER DATABASE command cannot override a service-level backup governance control, and the Azure Portal does not expose a supported bypass to reduce the locked period.
Accordingly, A is the only supported escalation path in the choices.

NEW QUESTION # 65
A company runs Oracle Exadata Database Service on Dedicated Infrastructure on Oracle AI Database@Azure and must retain full database backups for up to 10 years to satisfy a financial services regulation. The compliance team also requires that these backups cannot be deleted or have their retention shortened before the mandated period expires, even by an administrator with backup-delete permissions. As the architect, you must select the backup configuration that satisfies both the long retention period and the immutability requirement. Choose ONE.
Answer: B
Explanation:
The correct solution combines Oracle Database Autonomous Recovery Service Long-Term Retention (LTR) with Retention Lock .
Recovery Service permits an LTR backup to be retained for up to 3,650 days-10 years . LTR backups are independent of the normal operational backup window and are designed specifically for compliance, regulatory, legal, and archival requirements.
Retention Lock adds the required immutability control. Oracle describes Retention Lock as an enforcement mechanism that protects retained backups against inadvertent changes and malicious actions such as ransomware. Once governed by the locked protection policy, backup retention cannot simply be shortened or deleted through normal backup-administration privileges before the protected period expires.
A 60-day Object Storage policy fails the ten-year requirement. Manual NFS backups lack the managed LTR and retention-lock framework, while Data Guard standby databases solve availability and disaster-recovery problems rather than replacing governed backup retention.
Therefore, C uniquely satisfies both long-term retention and immutability.

NEW QUESTION # 66
You have created a delegated subnet for an Exadata Infrastructure resource in Availability Zone 1. You now need to provision a second Exadata Infrastructure resource in Availability Zone 2 for disaster recovery. What should you do?
Answer: C
Explanation:
Cross-availability-zone Oracle AI Database@Azure disaster recovery requires separate networking constructs for the primary and standby deployments. Oracle's Data Guard prerequisite documentation specifies two Azure VNets , with each VNet containing one Oracle AI Database@Azure delegated subnet , when configuring Data Guard between different availability zones in the same Azure region.
A separate delegated subnet ensures that each Exadata deployment receives the correct network attachment, address space, routing, and zone-aligned connectivity. Oracle also requires the associated VNet address spaces to be non-overlapping.
Reusing the AZ1 delegated subnet for infrastructure located in AZ2 would therefore conflict with the supported topology. Self-peering a subnet is not an Azure networking construct and would provide no meaningful isolation. Removing delegation would be counterproductive because delegation to Oracle's database resource provider is fundamental to provisioning Oracle AI Database@Azure networking.
Thus, A is the correct deployment pattern.

NEW QUESTION # 67
Which network port must be open and tested to ensure SQL*Net connectivity between the source database and the ZDM Service Host during a ZDM Physical Online migration to Exadata on Oracle Database@Azure?
Answer: A
Explanation:
The standard Oracle listener and SQL Net port used in the documented ZDM Physical Online migration workflow is TCP 1521 . Oracle's Oracle AI Database@Azure ZDM migration procedure explicitly instructs administrators to test SQL Net connectivity by running tnsping between source and target database hosts using port 1521.
This connectivity is required because ZDM and its underlying migration technologies must establish database- level communication for prechecks, configuration, target instantiation, Data Guard configuration, synchronization, and migration orchestration. If the source or target listener has been intentionally configured to use a nondefault port, that configured listener port must be permitted instead.
Port 22 is used for SSH administration between the ZDM Service Host and managed hosts. Port 443 is associated with HTTPS-based cloud service and API communication. Port 2049 is conventionally associated with NFS and is relevant when migration workflows use NFS-based staging, but it is not SQL*Net.
Therefore, D. 1521 is the correct answer.

NEW QUESTION # 68
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: B
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 .
