Oracle 1z0-1124-25 Exam With Confidence Using Practice Dumps

Objective:Efficiently propagate on-premises route updates to multiple VCNs.

DRG Capabilities:Supports route distribution to attached VCNs.

Analyze Options:

A:Manual updates are inefficient and error-prone; unsuitable.

B:Centralized DRG with route distribution automates propagation; efficient.

C:Multiple DRGs add complexity and manual effort; inefficient.

D:Service Gateway is for OCI services, not route updates; incorrect.

Conclusion:Centralized DRG with route distribution is the most efficient method.

Route distribution in a DRG simplifies multi-region routing. The Oracle Networking Professional study guide notes, "Using a centralized DRG with route distribution enabled allows routes learned from on-premises networks to be automatically propagated to all attached VCNs, reducing management overhead" (OCI Networking Documentation, Section: DRG Route Distribution). This leverages OCI’s automation capabilities.

Requirements:Private subnet, no internet, access to other VCN subnets, HA database.

Analyze Components:

Public Subnet:Internet-exposed, against policy.

Private Subnet:No internet, aligns with policy.

Service Gateway:For OCI services, not ADB connectivity.

DRG:For inter-VCN routing.

NSGs:Granular traffic control.

Evaluate Options:

A:Public subnet violates no-internet policy; incorrect.

B:Service Gateway for Object Storage/Yum irrelevant to ADB; incomplete.

C:Private subnet, NSGs, DRG, and CIDR planning meet all needs; correct.

D:Public subnet with internet access; violates policy.

Conclusion:Option C is the most effective approach.

Autonomous Database requires private deployment for security. The Oracle Networking Professional study guide notes, "For Autonomous Database on Dedicated Exadata, use a private subnet with NSGs for access control and a DRG for inter-VCN connectivity, reserving CIDR for scalability" (OCI Networking Documentation, Section: Autonomous Database Networking). Service Gateway isn’t used for ADB access, but the private setup ensures compliance.

Context: Zero Trust assumes no trust, requiring strict isolation (micro-segmentation).

Option A: Bandwidth isn’t increased by segmentation—incorrect.

Option B: Segmentation may increase route tables for granularity, not reduce them—incorrect.

Option C: Micro-segmentation isolates workloads, limiting breach impact (blast radius)—core Zero Trust goal and correct.

Option D: Inter-region connectivity isn’t simplified by micro-segmentation—incorrect.

Conclusion: Option C aligns with Zero Trust principles.

Oracle notes:

"Micro-segmentation in OCI VCNs, using NSGs and security lists, limits the blast radius of breaches by isolating resources, a key Zero Trust principle."This supports Option C. Reference:Zero Trust in OCI - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Concepts/zerotrust.htm).
