Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q76-Q81):

NEW QUESTION # 76
Your company is migrating its on-premises data center to OCI. A critical security requirement is to maintain centralized logging and auditing of all network traffic traversing the OCI Network Firewall. You need to ensure that every session that passes through the firewall is logged and can be analyzed for security events.
Which OCI service should you configure in conjunction with the Network Firewall to achieve this centralized logging?

A. OCI Cloud Guard.
B. OCI Audit Service.
C. OCI Logging Analytics.
D. OCI Service Connector Hub with OCI Logging.

Answer: D

Explanation:
* 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.

NEW QUESTION # 77
Which of the following is a disadvantage of using a public internet-based VPN connection for migrating large datasets from another cloud provider to OCI?

A. VPN connections cannot be automated using Infrastructure as Code (IaC) tools
B. VPN connections are inherently less secure than dedicated private connections
C. VPN connections are not compatible with all OCI services
D. The throughput of a VPN connection is limited by the available bandwidth and latency of the public internet

Answer: D

Explanation:
* 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).

NEW QUESTION # 78
You are setting up a Site-to-Site VPN connection between your on-premises network and OCI. You have generated the IKE pre-shared key and configured the VPN connection in OCI. You now need to configure your on-premises Customer Premises Equipment (CPE). Which information from the OCI console is ESSENTIAL for configuring your on-premises CPE to establish the VPN connection?

A. The public IP address of the OCI Dynamic Routing Gateway (DRG) and the IKE pre-shared key.
B. The OCI region and availability domain.
C. The OCID (Oracle Cloud Identifier) of the VPN connection and the compartment ID.
D. The subnet CIDR blocks within your OCI VCN.

Answer: A

Explanation:
* Objective: Identify essential info for CPE to establish a Site-to-Site VPN with OCI.
* Option A: Region and availability domain are for OCI resource placement, not CPE config-incorrect.
* Option B: The DRG's public IP is the VPN endpoint, and the IKE pre-shared key authenticates the tunnel-essential and correct.
* Option C: OCID and compartment ID are for OCI management, not CPE setup-incorrect.
* Option D: Subnet CIDRs are for routing, configured later, not for tunnel establishment-incorrect.
* Conclusion: Option B provides the critical VPN connection details.
Oracle documentation states:
* "To configure your CPE for Site-to-Site VPN, you need the public IP address of the DRG (VPN headend) and the IKE pre-shared key from the OCI console."This confirms Option B. Reference:Setting Up IPSec VPN - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks
/settingupIPSec.htm).

NEW QUESTION # 79
You are designing a microservices-based application on OCI. Each microservice is deployed as a container in Oracle Container Engine for Kubernetes (OKE). You want to expose these microservices through a single entry point using a Layer 7 load balancer and route traffic based on the request path. Which OCI load balancing integration method with OKE is the MOST appropriate and efficient?

A. Manually create a Regional Load Balancer and configure backend sets with the private IP addresses of the Kubernetes worker nodes hosting the microservices.
B. Deploy a Kubernetes LoadBalancer service, which automatically provisions an OCI Regional Load Balancer to distribute traffic to the microservice pods.
C. Deploy a Kubernetes NodePort service for each microservice and configure an OCI NetworkLoad Balancer to forward traffic to the NodePort services on the worker nodes.
D. Deploy a Kubernetes Ingress controller that leverages an OCI Regional Load Balancer to route traffic to the microservice pods based on Ingress rules.

Answer: D

Explanation:
* 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).

NEW QUESTION # 80
Your company is migrating its legacy application to OCI. This application uses self-signed certificates. As part of the migration, you want to replace these with certificates issued by a trusted Certificate Authority (CA) managed through OCI Certificates. What is the most secure and recommended method to handle this transition?

A. Import the self-signed certificates into OCI Certificates and continue using them until they expire.
B. Obtain certificates from OCI Certificates, gradually replace self-signed certificates on application servers, and update the truststores on client systems to include the OCI Certificates CA.
C. Configure OCI WAF to bypass certificate validation for the legacy application.
D. Immediately replace the self-signed certificates on all application servers with certificates issued by OCI Certificates, without any gradual rollout.

Answer: B

Explanation:
* Objective: Securely transition from self-signed to trusted CA certificates.
* Option A: Importing self-signed certificates into OCI Certificates doesn't improve security-incorrect.
* Option B: Immediate replacement risks outages if clients don't trust the new CA-unrecommended.
* Option C: Gradual replacement with OCI Certificates, updating client truststores, ensures security and minimizes disruption-correct.
* Option D: Bypassing validation via WAF weakens security-incorrect.
* Conclusion: Option C is the most secure and recommended method.
Oracle advises:
* "Replace self-signed certificates with OCI Certificates from a trusted CA. Perform a phased rollout and update client truststores to avoid disruptions."This validates Option C.
