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

Goal:Protect web servers from SQL injection using Network Firewall.

Firewall Features:

Stateful Inspection:Basic traffic tracking, limited exploit detection.

IDPS:Detects and prevents exploits via signatures.

URL Filtering:Blocks URLs, not payload-based attacks.

Geo-location:Blocks regions, not specific threats.

Evaluate Options:

A:Default IPS lacks SQL injection specificity; insufficient.

B:IDPS with custom signatures targets SQL injection; most suitable.

C:URL Filtering doesn’t address SQL injection payloads; incorrect.

D:Geo-location is broad, not precise; ineffective.

Conclusion:IDPS with custom rules is the best feature.

IDPS in OCI Network Firewall is designed for exploit prevention. The Oracle Networking Professional study guide explains, "The Intrusion Detection and Prevention System (IDPS) uses signatures to detect and block specific threats like SQL injection, with custom rule sets for tailored protection" (OCI Networking Documentation, Section: Network Firewall IDPS). This ensures precise defense against web exploits.

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.

Objective: Identify a VPN disadvantage for large dataset migration.

Option A: VPNs can be secure with IPSec; not inherently less secure—incorrect.

Option B: VPNs are automatable with IaC (e.g., Terraform)—incorrect.

Option C: Public internet limits VPN throughput due to bandwidth and latency variability—correct disadvantage.

Option D: VPNs are compatible with OCI services—incorrect.

Conclusion: Option C is the key disadvantage.

Oracle notes:

"Public internet-based VPNs face throughput limitations due to bandwidth and latency variability, impacting large data migrations.”This supports Option C. Reference:VPN Limitations - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/settingupIPSec.htm#limitations).

Constraints: High bandwidth, low latency, secure private connection, redundancy.

Option A: Single VPN Connect offers security but lacks high bandwidth, low latency, and redundancy—unsuitable for migration needs.

Option B: Multiple VPNs improve redundancy but still rely on public internet, limiting bandwidth and latency performance compared to dedicated circuits.

Option C: Single FastConnect provides high bandwidth, low latency, and privacy via a dedicated line, but lacks redundancy.

Option D: Multiple FastConnect circuits ensure high bandwidth and low latency with redundancy. Adding multiple VPNs as backup enhances resilience, meeting all constraints.

Conclusion: Option D is the most suitable and resilient, balancing performance and continuity.

Oracle states:

"FastConnect provides a private, high-bandwidth, low-latency connection to OCI. Use multiple circuits for redundancy."

"Combine FastConnect with IPSec VPN for additional failover options."Option D aligns with this guidance. Reference:FastConnect Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/fastconnect.htm).
