NEW QUESTION # 83
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: B
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 # 84
To achieve continuous availability and automated database failover using Data Guard Fast-Start Failover (FSFO) across availability zones in Oracle AI Database@Azure, where is it recommended to host the client- side Observer process?
Answer: C
Explanation:
The Data Guard Observer is an independent process used by Fast-Start Failover to monitor the primary and standby databases and determine whether an automatic failover should occur. Because its independence directly affects the reliability of the failover decision, it should not share the same failure domain as either database.
For an Oracle AI Database@Azure architecture spanning availability zones, placing the Observer on a separate Azure VM in another availability zone provides appropriate fault isolation. If the primary AZ fails, the Observer remains available to verify the failure and initiate the transition to the standby. Hosting the Observer directly on the primary database node would cause it to disappear with a primary-site outage.
Hosting it on the standby similarly creates an undesirable dependency on the standby environment.
The Observer is an external Data Guard Broker process; it does not belong inside Oracle's multicloud control- plane Parent Site. For stronger resilience, Oracle Data Guard can also support multiple observers in appropriate configurations.
Therefore, D represents the recommended architecture.

NEW QUESTION # 85
What is the allowed range of days for the automatic backup retention period when configuring an instance of Oracle Autonomous AI Database Serverless in Oracle AI Database@Azure?
Answer: A
Explanation:
Oracle Autonomous AI Database Serverless allows administrators to configure the automatic backup- retention window according to business recovery and compliance requirements. Oracle's current Autonomous AI Database provisioning documentation specifies an allowable automatic backup-retention range of 1 through 60 days .
Within that period, the database can be restored and recovered to an appropriate point in time, subject to the normal Autonomous AI Database backup and recovery mechanisms. A longer retention window provides a broader point-in-time recovery horizon but must also be considered alongside governance, compliance, and backup-protection requirements.
Oracle also supports Backup Retention Lock , which materially changes administrative behavior. When the retention period is locked, administrators cannot simply disable the lock or alter the protected retention setting through ordinary provisioning controls; Oracle Support intervention is required for those changes. This distinction is important for regulated workloads where backup immutability or protection from malicious administrative actions is required.
The alternatives beginning at seven days incorrectly raise the minimum, while the 30-day options incorrectly reduce the supported maximum. The complete configurable range is therefore 1-60 days .

NEW QUESTION # 86
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: A
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 # 87
Which two resources can be dynamically associated with an Oracle AI Database@Azure delegated subnet in Azure to manage traffic routing and filtering? (Choose two.)
Answer: A,C
Explanation:
An Oracle AI Database@Azure delegated subnet remains part of the customer's Azure VNet and can use supported Azure networking controls. Two fundamental controls are Network Security Groups (NSGs) and Azure route tables containing User-Defined Routes .
An NSG performs traffic filtering by applying inbound and outbound security rules based on criteria such as source, destination, protocol, and port. This allows organizations to enforce database-access policies at the Azure network layer. Route tables provide forwarding control, allowing traffic to be directed through Azure Firewall, an NVA, a virtual network gateway, or other supported next-hop architecture.
Oracle's delegated-subnet design documentation explicitly states that because the delegated subnet belongs to the customer's VNet, it can leverage Azure networking capabilities including NSGs and routing tables . This enables private application-to-database communication while retaining enterprise routing and security controls.
Azure Load Balancer backend pools and Application Gateway ingress controllers are application/load- balancing constructs and are not the two subnet-associated controls identified for this Oracle database networking requirement.
