NEW QUESTION # 89
You have deployed a primary Exadata VM cluster in one Azure region and a standby in a distant paired region using Active Data Guard. Round-trip latency between the regions exceeds the threshold for synchronous redo transport, but the application requires zero data loss on regional failover. What should you configure?
Answer: A
Explanation:
Oracle Active Data Guard Far Sync is specifically designed to provide zero-data-loss protection when the physical standby database is too geographically distant for direct synchronous redo transport without unacceptable primary-database latency.
The primary database sends redo synchronously to a nearby Far Sync instance. Because the Far Sync instance is positioned within low network latency of the primary, the primary can obtain the acknowledgement required for zero-data-loss protection without waiting for communication with the distant standby. Far Sync then forwards the redo asynchronously across the higher-latency interregional connection to the remote standby.
Oracle's Oracle Database@Azure reference architecture explicitly uses this pattern: the primary sends redo in SYNC mode to its local Far Sync instance, which forwards it in ASYNC mode to the remote standby database.
Maximum Performance using ASYNC alone permits a potential data-loss window. A snapshot standby is intended primarily for temporary read/write testing. Fast-Start Failover automates role transitions but requires an Observer and does not independently solve the synchronous-transport latency problem.
Therefore, C is correct. Study Guide reference: HA and DR - Active Data Guard Far Sync and zero-data- loss cross-region protection.
NEW QUESTION # 90
Which service is Oracle's native, recommended tool to orchestrate and automate database-level role transitions (switchover and failover) across regions for Oracle Database@Azure?
Answer: C
Explanation:
Oracle recommends OCI Full Stack Disaster Recovery (Full Stack DR) for orchestrating disaster-recovery operations around Oracle Database@Azure deployments.
Oracle's reference architecture for local and regional Oracle Database@Azure standbys explicitly recommends Full Stack DR to orchestrate database switchover and failover operations . The service can coordinate ordered disaster-recovery plans instead of requiring administrators to manually perform every database and infrastructure transition during an incident or DR drill.
Oracle Data Guard remains the underlying database replication and role-management technology, while Full Stack DR provides the higher-level orchestration framework for executing coordinated transitions.
Azure Site Recovery is primarily designed for Azure VM and workload replication/recovery and is not Oracle's recommended database-role orchestration service. GoldenGate provides logical replication and data integration rather than end-to-end DR orchestration. Azure Traffic Manager performs DNS-based traffic distribution and can participate in application routing, but it does not execute Oracle database switchovers or failovers.
Therefore, B is correct.

NEW QUESTION # 91
Which two are valid managed backup destinations for automatic backups of an Exadata Database in Oracle AI Database@Azure? (Choose two.)
Answer: C,D
Explanation:
The two managed backup destinations represented in the question are OCI Object Storage and Oracle Database Autonomous Recovery Service .
OCI Object Storage is the established managed backup destination for Oracle Database services and stores Oracle-managed database backup objects in OCI. Autonomous Recovery Service is Oracle's recommended advanced database-protection platform. It provides database-aware incremental-forever backup processing, centralized protection policies, recoverability validation, retention locking, and optional real-time transaction protection.
For Oracle Database@Azure, Recovery Service can store protected-database backups either in the paired OCI region or, where supported and selected by policy, within the same Azure cloud provider location. Oracle architecture documentation therefore increasingly positions Autonomous Recovery Service as the preferred automatic-backup destination.
The physical Zero Data Loss Recovery Appliance is an on-premises engineered system rather than the managed cloud backup destination in this service. Direct Azure Blob Storage API access is likewise not presented as the standard built-in automatic Exadata backup destination; Azure-hosted Recovery Service storage is accessed through the managed Recovery Service architecture rather than direct customer Blob APIs.
Therefore, C and D are correct.
Study Guide reference: Provision and operate Oracle AI Database@Azure Resources - Exadata backup destinations and Autonomous Recovery Service.
NEW QUESTION # 92
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 # 93
What is the subnet requirement for configuring an OCI Hub VCN to enable transit routing for Active Data Guard traffic between Oracle Database@Azure regions?
Answer: D
Explanation:
Oracle's reference architecture for multi-region Oracle Database@Azure disaster recovery explicitly states that no subnet is required in the Hub VCN to enable transit routing .
The Hub VCN serves primarily as a routing construct connecting gateways and route-table attachments.
DRGs, Local Peering Gateways, Remote Peering Connections, and VCN route tables provide the required network forwarding between the Oracle Database@Azure Child Site VCNs and remote regions. Because the hub does not need to host compute instances or network virtual appliances for this gateway-based transit model, it does not require a workload subnet.
This has an additional design benefit: the hub VCN can use a comparatively small CIDR range because there is no requirement to reserve substantial address space for servers or VNICs.
A public subnet and Internet Gateway are unnecessary because Data Guard traffic should traverse private cloud networking. Likewise, dedicated /24 transit-appliance subnets or per-availability-domain private subnets are not mandatory for the gateway-based topology.
Therefore, D is correct.
