Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q79-Q84):

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

Answer: B

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 needs to establish a secure connection between your on-premises network and OCI for a pilot project. The project has a limited budget and requires a quick setup, but also demands that the connection is encrypted. The long-term plan involves migrating to FastConnect, but that will take several months. Which OCI VPN solution would be most suitable for this short-term, budget-conscious, and security-aware scenario?

  • A. Use a Dynamic Routing Gateway (DRG) with a Site-to-Site VPN connection configured using dynamic routing with BGP.
  • B. Deploy a third-party virtual appliance VPN solution from the OCI Marketplace within a public subnet and configure a VPN connection to your on-premises network.
  • C. Use a Service Gateway to connect to a third-party VPN service available on the internet.
  • D. Use a Dynamic Routing Gateway (DRG) with a Site-to-Site VPN connection configured using static routing.

Answer: D

Explanation:
* Requirements:Quick, cheap, encrypted VPN; interim before FastConnect.
* VPN Options:
* Static VPN:Simple, native, low cost.
* Third-Party Appliance:Complex, costly.
* Service Gateway:Not for VPN; incorrect.
* BGP VPN:Dynamic, more setup; less quick.
* Evaluate Options:
* A:Static VPN is fast, secure, budget-friendly; correct.
* B:Appliance adds cost and complexity; incorrect.
* C:Misaligned use of Service Gateway; incorrect.
* D:BGP is overkill for pilot; less efficient.
* Conclusion:Static VPN via DRG is most suitable.
Static VPN is ideal for quick setups. The Oracle Networking Professional study guide notes, "A Site-to-Site VPN with static routing via DRG provides a fast, encrypted connection for short-term needs, minimizing cost and setup time" (OCI Networking Documentation, Section: Site-to-Site VPN). This fits the pilot project perfectly.


NEW QUESTION # 81
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?

  • A. There is a misconfiguration in the security rules, blocking the IKE or ESP (Encapsulating Security Payload) traffic.
  • B. The on-premises Customer-Premises Equipment (CPE) is configured with an incorrect public IP address.
  • C. The on-premises firewall is configured with incorrect NAT-Traversal settings.
  • D. The OCI Dynamic Routing Gateway (DRG) is experiencing a temporary outage.

Answer: A

Explanation:
* Symptoms:VPN tunnel drops intermittently despite stable internet and IKE settings.
* VPN Components:Requires IKE (UDP 500/4500) and ESP (IP 50) traffic.
* Evaluate Options:
* A:Incorrect CPE IP would prevent tunnel establishment, not intermittent drops; incorrect.
* B:DRG outage would cause full downtime, not intermittent; unlikely.
* C:Security rules blocking IKE/ESP intermittently (e.g., rate limiting) is common; most likely.
* D:NAT-Traversal issues typically prevent initial setup, not intermittent drops; less likely.
* Conclusion:Security rule misconfiguration is the most probable cause.
VPN stability depends on unblocked IKE and ESP traffic. The Oracle Networking Professional study guide notes, "Intermittent VPN tunnel drops are often caused by security rules or firewalls blocking IKE (UDP 500
/4500) or ESP (IP Protocol 50) traffic" (OCI Networking Documentation, Section: Site-to-Site VPN Troubleshooting). This aligns with the scenario's symptoms.


NEW QUESTION # 82
Which OCI component facilitates transitive routing between VCNs in different regions via a dedicated, private network backbone, while also enabling connectivity to on-premises networks?

  • A. Dynamic Routing Gateway (DRG)
  • B. Internet Gateway
  • C. Service Gateway
  • D. Local Peering Gateway (LPG)

Answer: A

Explanation:
* Requirement:Transitive routing across regions and to on-premises, privately.
* Components:
* LPG:Intra-region VCN peering; limited scope.
* DRG:Cross-region and on-premises routing via private backbone.
* Service Gateway:OCI service access; not transitive.
* Internet Gateway:Public internet; not private.
* Evaluate Options:
* A:Region-specific; incorrect.
* B:Supports multi-region and on-premises; correct.
* C:Service-focused; incorrect.
* D:Public; incorrect.
* Conclusion:DRG is the key component.
DRG enables complex routing scenarios. The Oracle Networking Professional study guide notes, "The Dynamic Routing Gateway (DRG) facilitates transitive routing between VCNs in different regions and on- premises networks over OCI's private backbone" (OCI Networking Documentation, Section: Dynamic Routing Gateway). This meets both requirements efficiently.


NEW QUESTION # 83
Your security policy mandates that all communication between your compute instances in a private subnet and OCI Object Storage must be authenticated and authorized using IAM policies and not rely on public IP addresses. Which OCI networking feature is the most appropriate to satisfy this requirement?

  • A. Public Subnet with a Network Firewall and IAM rules.
  • B. Private Subnet with a NAT Gateway and IAM rules.
  • C. Public Subnet with an Internet Gateway and IAM rules.
  • D. Private Subnet with a Service Gateway and IAM rules.

Answer: D

Explanation:
* Requirement: Private, IAM-secured access to Object Storage.
* Option A: Public subnet with Internet Gateway uses public IPs-violates policy.
* Option B: NAT Gateway is for internet access, not private OCI services-incorrect.
* Option C: Service Gateway enables private access to Object Storage, paired with IAM for auth- correct.
* Option D: Public subnet with firewall still relies on public IPs-incorrect.
* Conclusion: Option C meets all requirements.
Oracle states:
* "Use a Service Gateway for private access to OCI Object Storage from a private subnet, with IAM policies for authentication and authorization."This supports Option C. Reference:Service Gateway Overview - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/servicegateway.
