1z0-1124-25 Exam Dumps - Oracle Cloud Infrastructure Questions and Answers

Goal: End-to-end encryption (client-to-LB and LB-to-backend).

Option A: HTTP backend set leaves LB-to-backend unencrypted—incorrect.

Option B: HTTPS listener and backend set with certificates ensures full encryption—correct and mandatory.

Option C: Backend-only certificates lack LB termination—incorrect.

Option D: TCP proxy bypasses LB encryption—incorrect.

Conclusion: Option B is mandatory for end-to-end encryption.

Oracle states:

"For end-to-end encryption, configure the HTTPS listener with an SSL certificate and set the backend protocol to HTTPS, requiring certificates on backend instances."This validates Option B.

Requirements:Low latency, high bandwidth, multi-region VCNs via one FastConnect, minimal cost/overhead.

DRG Strategy:

Multiple DRGs:Increases cost and complexity.

Single DRG:Centralizes management, reduces FastConnect attachments.

Evaluate Options:

A:Multiple DRGs and FastConnects; costly and complex; incorrect.

B:Remote peering connections imply RPC, not standard DRG attachments; less precise.

C:Single DRG with remote peering attachments; efficient and correct terminology; optimal.

D:LPGs are intra-region, not cross-region; incorrect.

Conclusion:Single DRG with remote peering attachments is most efficient.

A single DRG optimizes multi-region setups. The Oracle Networking Professional study guide notes, "For connecting multiple VCNs across regions to a single FastConnect, use one DRG with remote peering attachments to minimize cost and management overhead" (OCI Networking Documentation, Section: DRG with FastConnect). Option C aligns with OCI’s recommended architecture.

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.

Problem Scope:Identify and adjust WAF rules causing false positives in Detection mode without disrupting traffic.

Detection Mode Behavior:Logs potential violations without blocking, allowing analysis.

Evaluate Options:

A:Use OCI Logging Analytics to pinpoint rule IDs from logs, then set rules to "log only" for testing; efficient and non-disruptive.

B:Disabling all rules risks security and is time-consuming; inefficient.

C:Increasing sensitivity worsens false positives; counterproductive.

D:Whitelisting IPs is a temporary fix, not scalable or diagnostic; unsuitable.

Conclusion:Logging analysis with rule adjustment is the most efficient approach.

OCI WAF logs provide detailed insights for troubleshooting. The Oracle Networking Professional study guide states, "In Detection mode, WAF logs all triggered rules, which can be analyzed in OCI Logging Analytics to identify false positives. Rules can then be adjusted to 'log only' to refine policies without affecting traffic" (OCI Networking Documentation, Section: Web Application Firewall). This method ensures precision and minimal disruption.

Objective: Improve OCI-AWS data transfer performance.

Option A: Region distance affects latency—valid.

Option B: Dedicated interconnect boosts bandwidth and stability—valid.

Option C: Compute pricing doesn’t influence inter-cloud bandwidth—invalid.

Option D: WAN optimization can enhance transfer efficiency—valid.

Conclusion: Option C is not a design consideration for performance.

Oracle notes:

"To optimize OCI-AWS connectivity, consider region proximity, dedicated interconnects, or WAN optimization. Compute pricing is unrelated to network performance."This excludes Option C.

Requirement Analysis: Strict compliance mandates logging all user access to private resources in a multi-tier setup.

Option A Assessment: Dynamic port forwarding with no logging fails compliance, as it provides no audit trail.

Option B Assessment: Managed Bastion sessions in OCI offer detailed logging (e.g., session start/end times, user IDs), integrated with OCI Logging. This meets compliance needs with a managed, scalable solution.

Option C Assessment: SSH port forwarding with minimal logs doesn’t provide the detailed auditing required for strict compliance.

Option D Assessment: A jump server with manual logging is error-prone, lacks scalability, and isn’t a managed OCI service, making it less suitable.

Conclusion: Option B provides the most robust, compliance-ready solution with detailed logging.

From Oracle’s Bastion documentation:

"OCI Bastion provides managed SSH sessions with detailed logging capabilities, capturing user access details for audit and compliance. Enable session logging to record all activities."This supports Option B as the best choice.
