Goal: Maximum security and isolation for IPSec over FastConnect.

Option A: Direct IPSec between on-premises networks bypasses OCI, ensuring complete isolation—correct and most secure.

Option B: NSGs/security lists control traffic but allow OCI traversal, less isolated—incorrect.

Option C: Third-party firewall adds complexity and OCI dependency, reducing isolation—incorrect.

Option D: Flow logs monitor, don’t isolate—incorrect.

Conclusion: Option A provides the highest isolation.

Oracle notes:

"For maximum isolation with third-party networks, configure IPSec directly between on-premises endpoints, avoiding OCI traversal."This supports Option A. Reference:IPSec over FastConnect - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/settingupIPSec.htm#fastconnect).

Objective: Reduce latency for remote users accessing private resources via Bastion.

Option A: Single Bastion increases latency for distant users—incorrect.

Option B: Multiple regional Bastions minimize latency by proximity—correct.

Option C: Dynamic port forwarding doesn’t address geographic latency—incorrect.

Option D: Load balancer aids HA, not latency reduction—incorrect.

Conclusion: Option B optimizes latency.

Oracle notes:

"Deploy Bastion hosts in multiple regions to reduce latency for geographically dispersed users accessing private resources."This supports Option B. Reference:Bastion Service Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Bastion/Concepts/bastionoverview.htm).

Requirements: Low latency, high security with encryption for migration.

Option A: VPN with IPSec offers encryption but has higher latency over public internet—less optimal.

Option B: ExpressRoute and FastConnect provide a private, low-latency link; TLS adds end-to-end encryption—correct and best combination.

Option C: Data Factory with HTTPS is encrypted but slow and not real-time—incorrect.

Option D: VPN with Load Balancer SSL termination breaks end-to-end encryption—incorrect.

Conclusion: Option B balances performance and security.

Oracle notes:

"For latency-sensitive migrations, use FastConnect with ExpressRoute via colocation, enhanced by TLS for secure, high-performance data transfer.”This supports Option B. Reference:Multicloud Connectivity - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Concepts/multicloud.htm).

Requirement: Low-latency, direct access to an on-premises SQL Server via FastConnect.

Option A: Internet Gateway with a public endpoint exposes the SQL Server to the internet, increasing latency and security risks—incorrect.

Option B: Service Gateway is for OCI services (e.g., Object Storage), not on-premises resources—incorrect.

Option C: FastConnect with a DRG provides a private, low-latency link. No additional OCI endpoint is needed; the SQL Server’s private IP is accessed directly via DRG routing—correct.

Option D: Private Endpoints are for OCI services within the VCN (e.g., ADB), not on-premises resources—incorrect.

Conclusion: Option C leverages FastConnect and DRG for direct, secure access.

Oracle documentation notes:

"FastConnect with a DRG enables private, low-latency connectivity to on-premises networks. Configure route tables to access on-premises resources directly; no additional endpoints are required."This supports Option C. Reference:FastConnect Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/fastconnect.htm).

Purpose:Secure access to private subnet resources via Bastion.

Placement Considerations:Must be internet-accessible yet isolated.

Evaluate Options:

A:Private subnet lacks internet access for Bastion; incorrect.

B:Dedicated public subnet balances accessibility and isolation; correct.

C:Separate VCN adds complexity, unnecessary; less optimal.

D:Ambiguous phrasing, but implies exposure; less precise than B.

Conclusion:Dedicated public subnet is the best placement.

OCI Bastion requires public access with security. The Oracle Networking Professional study guide notes, "Place the Bastion host in a public subnet with a dedicated configuration to allow secure SSH access to private subnet resources without exposing them directly" (OCI Networking Documentation, Section: Bastion Host Placement). Option B ensures this balance.
