Oracle Updated 1z0-1124-25 Exam Questions and Answers by lochlan

Goal: Support Zero Trust with packet flow monitoring.

Option A: Static routing defines paths, not monitoring—incorrect.

Option B: Security lists control access, not monitor—incorrect.

Option C: Flow logs track traffic; audit trails log actions—essential for Zero Trust—correct.

Option D: Public IPs enable access, not monitoring—incorrect.

Conclusion: Option C is essential.

Oracle states:

"Flow logs and audit trails provide continuous monitoring and verification of packet flows, critical for Zero Trust Packet Routing."This supports Option C. Reference:Zero Trust in OCI - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Concepts/zerotrust.htm).

Requirement:Private VCN connection across tenancies.

Services:

Internet Gateway:Public access; incorrect.

Service Gateway:OCI services, not VCNs; incorrect.

RPC:Cross-tenancy private peering; correct.

DRG with LPG:LPG is intra-region, not cross-tenancy; incorrect.

Evaluate Options:

A:Public; incorrect.

B:Service-focused; incorrect.

C:Designed for this scenario; correct.

D:Misaligned components; incorrect.

Conclusion:RPC is the right service.

RPC enables cross-tenancy peering. The Oracle Networking Professional study guide notes, "Remote Peering Connections (RPCs) establish private connectivity between VCNs in different tenancies over OCI’s private backbone" (OCI Networking Documentation, Section: Remote Peering Connections). This ensures no public internet traversal.

Goal:Automate certificate renewal in OCI Certificates.

Feature Check:OCI Certificates supports automatic renewal.

Evaluate Options:

A:Manual renewal risks disruption; inefficient.

B:Automatic Renewal with DNS validation automates process; best fit.

C:Vault stores secrets, no renewal automation; incorrect.

D:False; OCI Certificates has auto-renewal; incorrect.

Conclusion:Automatic Renewal is the optimal feature.

OCI Certificates offers automated renewal. The Oracle Networking Professional study guide states, "Enable the 'Automatic Renewal' option in OCI Certificates and configure DNS validation to ensure certificates are renewed before expiration, preventing disruptions" (OCI Networking Documentation, Section: OCI Certificates). This leverages OCI’s built-in automation.

Zero Trust Context:Assumes no inherent trust, requiring explicit controls at all network stages.

Evaluate Principles:

Implicit Trust:Assumes trust, opposite of Zero Trust; incorrect.

Least Privilege:Grants minimal access, explicitly enforced; aligns with Zero Trust.

Perimeter Security:Relies on boundary protection, not Zero Trust; incorrect.

Network Segmentation:Isolates networks, a tactic not a principle; incomplete.

Conclusion:Least Privilege is the core principle for explicit access control.

Zero Trust Packet Routing in OCI emphasizes Least Privilege. The Oracle Networking Professional study guide states, "The Least Privilege principle in Zero Trust requires that access controls be explicitly defined and enforced at every network communication stage, ensuring no implicit trust" (OCI Networking Documentation, Section: Zero Trust Networking). This drives granular security policies.
