Oracle 1z0-1124-25 Exam With Confidence Using Practice Dumps

Requirement: Secure outbound connection to a public API without exposing the instance.

Option A: Internet Gateway allows inbound and outbound traffic, exposing the instance—violates policy.

Option B: NAT Gateway enables outbound-only internet access from a private subnet. A security list restricts traffic to the API’s IP, ensuring security—correct.

Option C: Service Gateway is for OCI services, not third-party APIs—incorrect.

Option D: DRG with FastConnect is for private connections (e.g., on-premises), not internet APIs—incorrect.

Conclusion: Option B meets the policy and connectivity needs.

Oracle notes:

"A NAT Gateway allows instances in a private subnet to initiate outbound internet traffic without receiving inbound connections. Use security lists to restrict destinations."This supports Option B. Reference:NAT Gateway Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/NATgateway.htm).

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).

Goal:Prefer FastConnect routes over public internet in OCI.

BGP Attributes:

Local Preference:Higher value prefers a path within an AS.

AS Path:Shorter path preferred, but manipulated on sender side.

Prefix Length:More specific wins, but not controllable here.

MED:Influences inbound traffic, not OCI preference.

Evaluate Options:

A:Higher Local Preference ensures FastConnect priority; correct.

B:AS Path is set by on-premises, not OCI; incorrect.

C:Prefix specificity is on-premises controlled; incorrect.

D:MED affects on-premises, not OCI; incorrect.

Conclusion:Local Preference is the right attribute.

Local Preference controls route preference in BGP. The Oracle Networking Professional study guide states, "To prioritize FastConnect routes in OCI, increase the Local Preference for routes learned via the FastConnect virtual circuit over other paths" (OCI Networking Documentation, Section: BGP Configuration). This ensures OCI prefers the private path.
