1Z0-1124-25 Exam Dumps and Practice Questions

Objective: Identify the service for Load Balancer traffic logs.

Option A: Flow Logs capture VCN traffic, not specific to Load Balancer---incorrect.

Option B: Service Logs are generic, not Load Balancer-specific---incorrect.

Option C: Load Balancer Logs provide detailed client and health check data---correct.

Option D: Audit Logs track API actions, not traffic---incorrect.

Conclusion: Load Balancer Logs are the best fit.

Oracle states:

'Load Balancer Logs offer detailed insights into client connections and backend health checks for Network Load Balancers.''

This validates Option C. Reference: Load Balancer Logging - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Balance/Tasks/managinglogs.htm).

Objective: Identify the feature for dynamic route learning via DRG.

Option A: Service Gateway is for OCI services---incorrect.

Option B: LPG is for VCN peering---incorrect.

Option C: BGP enables dynamic route exchange between DRG and on-premises---correct.

Option D: Internet Gateway is for public access---incorrect.

Conclusion: Option C is the correct feature.

Oracle notes:

'BGP on the DRG dynamically learns routes from on-premises networks over FastConnect or VPN, propagating them to VCNs.'

This confirms Option C. Reference: BGP with DRG - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Tasks/managingDRGs.htm#BGP).

Problem: Private subnet instances can't access Object Storage via Service Gateway.

Setup Check: Route rules point to Service Gateway; NSGs allow traffic.

Evaluate Causes:

A: Incorrect CIDR labels block Object Storage access; likely.

B: Internet Gateway irrelevant for Service Gateway; incorrect.

C: NSGs confirmed open, security lists secondary; less likely.

D: NAT Gateway not used here; incorrect.

Conclusion: Misconfigured Service Gateway CIDR is the most likely issue.

Service Gateway requires specific CIDR labels. The Oracle Networking Professional study guide states, 'For private subnets to access Object Storage via a Service Gateway, the gateway must be configured with the correct regional Oracle Services CIDR label' (OCI Networking Documentation, Section: Service Gateway Configuration). Misconfiguration prevents access despite proper routing.

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).

Requirement: Private communication between VCNs in different OCI regions via DRG.

Option A: LPGs are for same-region VCN peering, not cross-region---incorrect.

Option B: Service Gateways are for OCI service access, not VCN-to-VCN routing---incorrect.

Option C: Attaching both VCNs to a single DRG (via Remote Peering Connections implicitly) and configuring route tables enables cross-region communication over OCI's backbone. This is the standard approach.

Option D: Internet Gateways use public IPs, which is insecure and not private---incorrect.

Conclusion: Option C is the necessary configuration for DRG-based cross-region connectivity.

Oracle documentation confirms:

'To connect VCNs in different regions, attach each to a DRG using Remote Peering Connections (RPCs). Configure DRG route tables to route traffic between VCN CIDRs.'

Option C reflects this setup (RPCs are implied). Reference: VCN Peering Overview - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Tasks/remoteVCNpeering.htm).
