Documentation, Section: IPv6 Configuration). Without SLAAC, instances default to IPv4 only. Reference: Oracle Cloud Infrastructure Documentation - IPv6 Networking. You are troubleshooting an issue where legitimate users are occasionally blocked by your OCI WAF, which is configured in "Detection" mode. You need to identify the specific WAF rules that are triggering these false positives and adjust them without disrupting legitimate traffic. Which approach offers the most efficient way to diagnose and resolve this issue?
D. Using a Local Peering Gateway (LPG) to connect the network appliance to the DRG. Explanation: Objective: Enable transitive routing via a network appliance (e.g., firewall) between VCNs. Transitive Routing Setup: DRG connects VCNs; appliance processes traffic. Key Requirement: DRG must route traffic to the appliance’s private IP. Evaluate Options: A: Service Gateway is for OCI services, not transitive routing; incorrect. B: Static routes on DRG to appliance ensure correct traffic flow; essential. C: Load Balancer is optional, not essential for routing; incorrect. D: LPG is for intra-region VCN peering, not appliance -DRG connection; incorrect. Conclusion: DRG static routes to the appliance are critical for transitive routing. Transitive routing with a network appliance requires explicit routing configuration. The Oracle Networking Professional study guide notes, "To enable transitive routing through a network appliance, configure static routes in the DRG route table pointing to the appliance’s private IP as the next hop" (OCI Networking Documentation, Section: Transitive Routing with DRG). This ensures traffic is processed by the appliance between VCNs. Reference: Oracle Cloud Infrastructure Documentation - Dynamic Routing Gateway. Your company has a FastConnect circuit established between your on -premises data center and OCI. However, you have a specific regulatory requirement to encrypt all traffic, even over dedicated connections like FastConnect. You need to implement IPSec encryption without significantly impacting the available bandwidth of your FastConnect circuit. Which is the most effective approach to implement IPSec encryption over your existing FastConnect circuit, while maintaining high bandwidth?
with AES -256 add overhead, reducing bandwidth; less effective. C: Compute -based VPN is inefficient and public -facing; unsuitable. D: Public internet VPN violates privacy requirement; incorrect. Conclusion: DRG VPN with AES -GCM is the most effective solution. OCI supports IPSec over FastConnect via DRG. The Oracle Networking Professional study guide explains, "A Site -to-Site VPN over FastConnect using the DRG provides encrypted traffic with low - overhead algorithms like AES -GCM, maintaining high bandwidth" (OCI Networking Documentation, Section: FastConnect with VPN). This meets regulatory and performance needs efficiently. Reference: Oracle Cloud Infrastructure Documentation - Site-to-Site VPN over FastConnect. You have deployed a distributed application across OCI and Azure. You have established the OCI- Azure Interconnect. You are experiencing packet loss and performance degradation when transmitting large volumes of data between the two cloud providers. You have verified that the network devices on both sides are correctly configured. Which is NOT a typical root cause to investigate when troubleshooting performance issues across the OCI -Azure Interconnect?
You are managing a Site -to-Site VPN connection between your on -premises network and OCI. You notice that the VPN tunnel is frequently dropping and re -establishing. You have verified the internet connectivity at both ends and confirmed that the IKE (Internet Key Exchange) parameters are correctly configured. Which of the following is the most likely cause of the intermittent VPN tunnel disconnections?
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. Reference: Oracle Cloud Infrastructure Documentation - Service Connector Hub. You are a cloud architect designing a multi -tiered application on OCI. One tier consists of publicly accessible web servers that must be protected from common web exploits. You plan to use OCI Network Firewall to achieve this. You need to configure the Network Firewall to detect and prevent SQL injection attacks against the web servers. Which Network Firewall feature is most suitable for this purpose?
due to default behavior or SLAAC), but IPv4 requires explicit routing. Per the Oracle Networking Professional study guide, "Route tables must be configured to direct traffic to the appropriate next hop for inter-subnet communication within a VCN" (OCI Networking Documentation, Section: Virtual Cloud Networks). Reference: Oracle Cloud Infrastructure Documentation - Networking Overview, Route Tables. You are designing a backup solution in OCI. Compute instances in a private subnet need to back up data to OCI Object Storage. Security policy mandates that data transfer must not traverse the public internet. You need to choose the most secure and cost -effective method for accessing Object Storage. Which endpoint/gateway configuration should you implement?
