Oracle AI Database@Azure Architect Professional 1z0-1147 Prüfungsfragen mit Lösungen (Q85-Q90):

85. Frage
You have configured automatic backups for an Exadata Database using Object Storage with a 30-day retention period. A new compliance requirement now mandates that full backups be retained for up to 10 years with immutability. What should you do?

A. Switch to NFS as the backup destination.
B. Enable Autonomous Recovery Service and configure a long-term retention backup with retention lock.
C. Increase the Object Storage retention period to 3,650 days.
D. Rely on manual, on-demand backups only.

Antwort: B

Begründung:
Oracle Database Autonomous Recovery Service provides the specific capabilities required for multi-year database backup retention combined with immutability .
Oracle's Long-Term Retention capability allows a full database backup to be retained for up to ten years .
This addresses regulatory requirements that exceed ordinary operational backup-retention windows. Recovery Service additionally supports Retention Lock , which prevents protected backups from being modified or deleted before the configured retention period expires. This provides a database-aware immutability mechanism suitable for ransomware, malicious-administrator, and compliance-protection scenarios.
Merely increasing a standard Object Storage backup retention value does not provide the same Recovery Service lifecycle, recoverability validation, protection-policy model, or database-specific retention locking.
NFS likewise does not introduce a managed ten-year immutable recovery framework. Manual on-demand backups also fail to provide policy-enforced retention and introduce unnecessary operational risk.
The combination of Recovery Service, LTR, and Retention Lock directly addresses both requirements in the question: ten-year retention and immutability .
Therefore, B is correct.
Study Guide reference: Secure Oracle AI Database@Azure - Autonomous Recovery Service, Long- Term Retention and Retention Lock.

86. Frage
Which capability is provided by a Network Anchor in Oracle AI Database@Azure?

A. Encrypt data in transit between Azure and OCI using IPsec exclusively.
B. Provide DNS forwarding and listening endpoints between Azure and OCI.
C. Serve as the customer-managed key store for TDE.
D. Automatically create Availability Domains inside Azure regions.

Antwort: B

Begründung:
A Network Anchor provides the cross-cloud network integration context used by supported Oracle AI Database@Azure services, including important DNS-resolution capabilities between Azure and OCI .
For inbound DNS resolution toward Azure, Oracle's Network Control Plane can create an OCI forwarding DNS endpoint and associated forwarding rules. For Azure-to-OCI resolution, the service can create an OCI listening DNS endpoint and expose its address through the Network Anchor so Azure DNS infrastructure or on-premises DNS servers can forward queries for Oracle database namespaces.
When both directions are configured, the architecture provides bidirectional private DNS resolution between Azure and OCI environments. Network Anchors can also participate in private-zone synchronization depending on the database service and DNS configuration.
The Network Anchor is not a cryptographic key store; TDE keys belong in Oracle Wallet, OCI Vault, Oracle Key Vault, or Azure Key Vault. Nor does the Network Anchor create Azure Availability Zones/OCI Availability Domains or mandate an IPsec-only intercloud transport mechanism.
Therefore, B is correct.

87. Frage
Which two statements are true about the delegated subnet used by Oracle AI Database@Azure? (Choose two.)

A. Multiple VM clusters can be hosted within a single delegated subnet.
B. The CIDR range assigned to the delegated subnet must be a public IPv4 range.
C. Only one delegated subnet is allowed per Azure VNet.
D. Two Exadata Infrastructure resources in different availability zones can share one delegated subnet.

Antwort: A,C

Begründung:
Oracle's current network guidance defines two important delegated-subnet constraints. First, each Azure VNet can contain a maximum of one Oracle AI Database@Azure delegated subnet . Second, a single delegated subnet can support multiple VM Clusters , provided IP capacity and availability-zone constraints are satisfied.
Oracle clarifies that multiple VM Clusters from the same Exadata Infrastructure can share a delegated subnet.
VM Clusters belonging to different Exadata Infrastructure resources can also share one when those infrastructure resources reside in the same availability zone .
However, Exadata Infrastructure resources located in different availability zones cannot share the same delegated subnet. Oracle identifies such a configuration as producing a suboptimal network path and requires separate delegated networking for cross-zone deployments.
The delegated subnet also uses Azure private address space; it is not required to use-and should not be designed around-a public IPv4 CIDR range.
Therefore, A and C are correct.

88. Frage
You have successfully deployed a two-node Exadata VM Cluster on Oracle AI Database@Azure to provide hardware-level high availability using Oracle RAC. What client-side feature should you implement at the application layer to mask database node failures and transparently replay in-flight uncommitted transactions without throwing errors to end users?

A. Fast-Start Failover (FSFO)
B. Transparent Data Encryption (TDE)
C. Oracle Data Guard Broker
D. Oracle Application Continuity (AC)

Antwort: D

Begründung:
Oracle Application Continuity (AC) is the application-availability technology designed to mask recoverable database outages and replay database requests transparently after a connection is re-established.
Oracle RAC provides database-service continuity when one database instance or node becomes unavailable, but an application may still have active sessions or in-flight work on the failed instance. Application Continuity works with Oracle's high-availability connection infrastructure, database services, FAN, Transaction Guard, and supported clients to reconnect to an available instance and replay eligible database requests. This significantly reduces the application errors that would otherwise be exposed during node failure or planned maintenance.
Fast-Start Failover and Data Guard Broker operate at the Data Guard database-role and disaster-recovery level. They manage primary/standby transitions rather than transparently replaying an individual application session after a RAC node failure. Transparent Data Encryption protects database data at rest and has no role in request replay or failure masking.
Therefore, C. Oracle Application Continuity is correct.

89. Frage
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?

A. A VCN with a delegated subnet cannot establish direct Remote Peering Connections (RPCs).
B. Only one Dynamic Routing Gateway (DRG) is permitted per Virtual Cloud Network (VCN) in OCI.
C. The Dynamic Routing Gateway cannot route traffic across different cloud tenant subscriptions.
D. Only one Local Peering Gateway (LPG) can be attached to any individual VCN.

Antwort: B

Begründung:
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.
