Oracle 1Z0-1124-25 Exam Dumps

Needs: Private, dedicated connection for large data transfers to Object Storage.

Option A: VPN with Service Gateway uses public internet, limiting bandwidth---incorrect.

Option B: Internet Gateway exposes traffic publicly---incorrect.

Option C: FastConnect Private Peering provides a dedicated link, and Service Gateway ensures private Object Storage access---correct.

Option D: DRG with Internet Gateway isn't private---incorrect.

Conclusion: Option C best meets the need.

Oracle states:

'FastConnect Private Peering combined with a Service Gateway enables secure, high-bandwidth access to Object Storage from on-premises networks.'

This supports Option C. Reference: FastConnect and Service Gateway - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Tasks/fastconnect.htm#servicegateway).

Requirement Analysis: The solution must ensure private access to Object Storage without public internet traversal, while being cost-effective.

Evaluate OCI Components:

Internet Gateway: Provides public internet access, unsuitable for private connectivity.

NAT Gateway: Allows outbound internet access from private subnets, but traffic still exits OCI.

Service Gateway: Enables private access to OCI services like Object Storage within the same region.

DRG with FastConnect: Used for on-premises connectivity, not intra-OCI service access.

Option Assessment:

A: Uses public internet, violating the security policy.

B: HTTPS encrypts data, but traffic traverses the internet via NAT, violating the policy.

C: Service Gateway keeps traffic within OCI's private network, meeting security and cost goals.

D: Overly complex and costly, with public endpoints contradicting the requirement.

Conclusion: Service Gateway with regional Object Storage endpoints ensures private, secure, and cost-effective access.

The Service Gateway is designed for private access to OCI services like Object Storage, avoiding the public internet. The Oracle Networking Professional study guide states, 'A Service Gateway allows instances in a private subnet to access supported OCI services without an Internet Gateway or NAT Gateway, ensuring traffic remains within the Oracle network' (OCI Networking Documentation, Section: Service Gateway). Using the Oracle Services Network service CIDR label for the region ensures compatibility with Object Storage endpoints, optimizing cost and security.

Requirements: End-to-end encryption, no public internet for Object Storage access.

Options Analysis:

Service Gateway: Private access to Object Storage.

NAT Gateway: Public internet access; unsuitable.

Private Endpoint: Alternative private access, but newer feature.

HTTPS: Ensures in-transit encryption.

Evaluate Options:

A: Encryption at rest doesn't cover transit; incomplete.

B: NAT uses public internet; violates policy; incorrect.

C: Service Gateway with HTTPS ensures full encryption and privacy; correct.

D: Private Endpoint with HTTPS is valid but less common than Service Gateway; slightly less optimal historically.

Conclusion: Service Gateway with HTTPS is most secure and compliant.

Service Gateway is standard for private Object Storage access. The Oracle Networking Professional study guide states, 'A Service Gateway with HTTPS API calls ensures end-to-end encrypted traffic to Object Storage without public internet traversal' (OCI Networking Documentation, Section: Service Gateway). This meets security mandates effectively.

Requirement: Centralized logging of Network Firewall traffic for analysis.

OCI Services:

Audit Service: Logs API calls, not network traffic.

Logging Analytics: Analyzes logs but needs log ingestion.

Service Connector Hub with Logging: Moves firewall logs to OCI Logging.

Cloud Guard: Monitors security posture, not detailed logging.

Evaluate Options:

A: Audit Service is for API events; incorrect.

B: Logging Analytics requires log source; incomplete.

C: Service Connector Hub with Logging captures and stores firewall logs; best fit.

D: Cloud Guard is for threat detection, not logging; incorrect.

Conclusion: Service Connector Hub with OCI Logging meets the requirement.

OCI Network Firewall logs require integration with OCI Logging. The Oracle Networking Professional study guide states, 'Service Connector Hub can be configured to transfer Network Firewall logs to OCI Logging for centralized storage and analysis, meeting auditing requirements' (OCI Networking Documentation, Section: Network Firewall Logging). This ensures every session is logged and auditable.

Problem: OKE web tier pods cannot reach the application tier.

Traffic Flow: Web tier (OKE) initiates outbound (egress) traffic to application tier (port 8080).

NSG Role: Controls traffic at VNIC level; must allow egress from OKE and ingress to app tier.

Evaluate Options:

A: Missing egress rule on OKE NSG blocks traffic; plausible but incomplete context.

B: Ingress on OKE NSG affects incoming traffic, not outbound to app tier; incorrect.

C: No ingress on OKE NSG doesn't block egress to app tier; incorrect.

D: Egress limited to internet blocks app tier access (port 8080); most likely.

Conclusion: Missing egress rule to app tier NSG is the primary issue.

NSGs require explicit egress rules for outbound traffic. The Oracle Networking Professional study guide notes, 'For OKE pods to communicate with other tiers, the node pool's NSG must include egress rules to the destination NSG or CIDR on the required ports' (OCI Networking Documentation, Section: Network Security Groups with OKE). Option D reflects a common misconfiguration in IaC setups.
