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).

Goal: Lowest latency, highest bandwidth for AWS-to-OCI migration.

Option A: IPSec VPN over public internet has variable latency and limited bandwidth—incorrect.

Option B: Third-party cloud exchange with Direct Connect and FastConnect offers a private, dedicated link, minimizing latency and maximizing bandwidth—correct.

Option C: Storage Gateway over internet is slow and not dedicated—incorrect.

Option D: Transit Gateway with VPN uses public internet, lacking performance—incorrect.

Conclusion: Option B provides the best performance.

Oracle documentation notes:

"A third-party cloud exchange provider can interconnect AWS Direct Connect and OCI FastConnect, delivering a private, high-bandwidth, low-latency connection."This validates Option B. Reference:Multicloud Connectivity - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Concepts/multicloud.htm).

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).

Identify the Goal: Troubleshoot efficiently to determine if stateful inspection is causing intermittent connectivity issues.

Option A Evaluation: Disabling stateful inspection globally removes all security checks, potentially restoring connectivity but disrupting the entire VCN’s security. This is inefficient and risky.

Option B Evaluation: Creating a bypass rule for the application server avoids inspection, which could confirm the issue but weakens security for that server. It’s a workaround, not a diagnostic step, and requires policy changes during troubleshooting.

Option C Evaluation: Reviewing firewall logs for denied traffic is targeted and non-disruptive. Logs show if stateful inspection is dropping packets (e.g., due to session timeouts or rule mismatches), directly identifying the cause without altering configurations.

Option D Evaluation: Recreating the firewall is highly disruptive, time-consuming, and doesn’t guarantee insight into the current issue. It’s not a troubleshooting step.

Conclusion: Option C is the most efficient, as it leverages logs for precise diagnosis without impacting operations.

Per Oracle’s Network Firewall documentation:

"Network Firewall logs provide detailed information about allowed and denied traffic, including source/destination IPs, ports, and protocols. Use logs to troubleshoot connectivity issues by identifying dropped packets due to stateful inspection or rule mismatches."

"Stateful inspection tracks connection states; misconfigurations can lead to dropped sessions."This confirms logs are the best tool for diagnosing stateful inspection issues. Reference:Network Firewall Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/NetworkFirewall/overview.htm).

Goal: Layer 7 routing for OKE microservices via a single entry point.

Option A: Manual configuration is inefficient and doesn’t support path-based routing—incorrect.

Option B: LoadBalancer service provisions a Layer 4 balancer, not Layer 7 path routing—incorrect.

Option C: NodePort with NLB is Layer 4, less secure, and lacks path routing—incorrect.

Option D: Ingress controller with Regional Load Balancer (Application LB) provides Layer 7 routing based on paths—correct and efficient.

Conclusion: Option D is the best integration method.

Oracle states:

"Use a Kubernetes Ingress controller with OCI Regional Load Balancer for Layer 7 routing to OKE microservices based on request paths."This supports Option D. Reference:OKE Networking - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/ContEng/Tasks/contengnetworking.htm).

Requirements: High bandwidth, low latency, leveraging direct fiber connectivity.

Option A: Site-to-Site VPN uses the public internet, lacking consistency and bandwidth—incorrect.

Option B: Internet Gateway is for public access, not dedicated connections—incorrect.

Option C: FastConnect Colocation uses direct fiber at Oracle locations, ensuring high bandwidth and minimal latency—correct.

Option D: DRG with remote peering is for VCN-to-VCN connectivity, not optimized for on-premises fiber—incorrect (DRG is part of FastConnect but not the service itself).

Conclusion: FastConnect Colocation is the most suitable.

Oracle states:

"FastConnect Colocation with Oracle leverages direct fiber connections at Oracle facilities, providing consistent, high-bandwidth, and low-latency access to OCI."This supports Option C. Reference:FastConnect Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/fastconnect.htm#colocation).
