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

Goal: Capture and analyze traffic metadata for anomalies and troubleshooting.

Option A: NSGs control traffic but don’t capture metadata—incorrect.

Option B: Flow Logs record detailed traffic metadata (e.g., IPs, ports), perfect for analysis—correct.

Option C: Route Tables manage routing, not metadata—incorrect.

Option D: Service Gateway enables service access, not traffic logging—incorrect.

Conclusion: Flow Logs are best suited.

Oracle documentation confirms:

"Flow Logs capture network traffic metadata within a VCN, enabling anomaly detection and connectivity troubleshooting.”This supports Option B. Reference:Flow Logs Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Concepts/flowlogs.htm).

Requirements:Global access, geo-routing, advanced traffic management, DDoS protection.

Load Balancer Options:

Regional LB:Single-region, no global routing or advanced policies.

NLB:Layer 4, no HTTP-based traffic management or DDoS features.

Global LB with Steering Policies:Layer 7, supports geo-routing and policies.

Flexible LB:Not a specific OCI service.

Assess Fit:

A:Lacks global and advanced features; unsuitable.

B:No Layer 7 or DDoS protection; incorrect.

C:Meets all requirements with geo-routing, steering policies, and WAF integration; best fit.

D:Non-existent service; incorrect.

Conclusion:Global LB with steering policies is the best solution.

The Global Load Balancer with Traffic Management Steering Policies supports global applications. The Oracle Networking Professional study guide explains, "Global Load Balancer enables geo-based routing and advanced traffic policies like A/B testing and weighted distribution, integrating with OCI WAF for DDoS protection" (OCI Networking Documentation, Section: Load Balancing - Traffic Management). This aligns with all specified requirements.

Goal: Lowest latency, highest bandwidth for AWS-to-OCI migration.

Option A: IPSec VPN over public internet has variable latency and limited bandwidth—incorrect.

Option B: Third-party cloud exchange with Direct Connect and FastConnect offers a private, dedicated link, minimizing latency and maximizing bandwidth—correct.

Option C: Storage Gateway over internet is slow and not dedicated—incorrect.

Option D: Transit Gateway with VPN uses public internet, lacking performance—incorrect.

Conclusion: Option B provides the best performance.

Oracle documentation notes:

"A third-party cloud exchange provider can interconnect AWS Direct Connect and OCI FastConnect, delivering a private, high-bandwidth, low-latency connection."This validates Option B. Reference:Multicloud Connectivity - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Concepts/multicloud.htm).

Requirements: Private, low-latency cross-region VCN connectivity.

Option A: RPCs with route table updates enable private, direct peering via DRG—correct.

Option B: IPSec VPN adds latency over internet—incorrect.

Option C: Service Gateways are for OCI services—incorrect.

Option D: NAT Gateways use public IPs, not private—incorrect.

Conclusion: Option A is necessary.

Oracle states:

"Use Remote Peering Connections (RPCs) with DRG to connect VCNs across regions privately. Update route tables for CIDR routing."This supports Option A. Reference:Remote VCN Peering - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/remoteVCNpeering.htm).
