Oracle Cloud Infrastructure 2025 Networking Professional Sample Questions (Q78-Q83):

NEW QUESTION # 78
Your company needs to connect an on-premises data center to an OCI Virtual Cloud Network (VCN) to extend their existing infrastructure to the cloud. The connection MUST be secure, reliable, and provide consistent, low-latency access to resources in both environments. Resources in the OCI VCN need access to the on-premises servers, and resources in the on-premises data center need to access the compute instances located in a private subnet within the OCI VCN. Which is the MOST appropriate architectural design for establishing connectivity in this hybrid cloud environment, considering the available endpoints and gateway options in OCI?

A. Implement a Site-to-Site VPN connection between the on-premises network and the OCI VCN, utilizing a Dynamic Routing Gateway (DRG) in OCI.
B. Establish a FastConnect connection between the on-premises network and the OCI VCN, utilizing a Dynamic Routing Gateway (DRG) in OCI.
C. Configure a public endpoint for each resource in the OCI VCN that needs to be accessed from the on- premises network.
D. Implement a FastConnect connection from the on-premises network to the OCI VCN utilizing a Dynamic Routing Gateway (DRG) in OCI and implement a Site-to-Site VPN connection as backup.

Answer: D

Explanation:
* Requirements: Secure, reliable, low-latency, bidirectional access with redundancy.
* Option A: VPN via DRG is secure but lacks low latency and redundancy-insufficient.
* Option B: FastConnect via DRG offers low latency and security but no redundancy-partial fit.
* Option C: Public endpoints are insecure and high-latency-incorrect.
* Option D: FastConnect for primary low-latency access, VPN as backup for redundancy-correct and most appropriate.
* Conclusion: Option D meets all criteria.
Oracle states:
* "FastConnect with DRG provides secure, low-latency hybrid connectivity. Add a Site-to-Site VPN for redundancy to ensure reliability."This supports Option D. Reference:Hybrid Cloud Connectivity - Oracle Help Center(docs.oracle.com/en-us/iaas/Content/Network/Tasks/hybridcloud.htm).

NEW QUESTION # 79
Your team is deploying a critical, highly available application that relies on accessing a MySQL Database Service instance within OCI. The application requires a stable and predictable endpoint for database connectivity, even during database failover events. Which endpoint configuration is most suitable to ensure seamless application connectivity in this high-availability scenario?

A. Using the private IP address of the primary MySQL Database Service instance directly.
B. Using a DNS hostname that resolves to the floating private IP address of the active MySQL Database Service instance.
C. Using a Service Gateway to connect to the MySQL Database Service endpoint.
D. Using the public IP address of the MySQL Database Service instance.

Answer: B

Explanation:
* Goal:Stable endpoint for MySQL DB with HA failover support.
* Endpoint Options:
* Public IP:Exposed, changes on failover; unsuitable.
* DNS with Floating IP:Persistent across failovers; ideal.
* Private IP:Tied to primary, fails on switch; incorrect.
* Service Gateway:For OCI services, not MySQL DB; incorrect.
* Evaluate Options:
* A:Public exposure, no HA; incorrect.
* B:Floating private IP with DNS ensures continuity; correct.
* C:Static IP breaks on failover; incorrect.
* D:Misaligned purpose; incorrect.
* Conclusion:DNS with floating IP is most suitable.
MySQL DB in OCI uses floating IPs for HA. The Oracle Networking Professional study guide explains, "A DNS hostname resolving to the floating private IP of the active MySQL Database Service instance ensures seamless connectivity during failover events" (OCI Networking Documentation, Section: MySQL Database Service HA). This provides predictability and stability.

NEW QUESTION # 80
Which aspect of OCI's security framework is essential for continuous monitoring and verification of packet flows, a core requirement of Zero Trust Packet Routing?

A. Public IP address assignments
B. Flow logs and audit trails
C. Default security lists
D. Static routing configurations

Answer: B

Explanation:
* Goal: Support Zero Trust with packet flow monitoring.
* Option A: Static routing defines paths, not monitoring-incorrect.
* Option B: Security lists control access, not monitor-incorrect.
* Option C: Flow logs track traffic; audit trails log actions-essential for Zero Trust-correct.
* Option D: Public IPs enable access, not monitoring-incorrect.
* Conclusion: Option C is essential.
Oracle states:
* "Flow logs and audit trails provide continuous monitoring and verification of packet flows, critical for Zero Trust Packet Routing."This supports Option C. Reference:Zero Trust in OCI - Oracle Help Center (docs.oracle.com/en-us/iaas/Content/Network/Concepts/zerotrust.htm).

NEW QUESTION # 81
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 Ingress controller that leverages an OCI Regional Load Balancer to route traffic to the microservice pods based on Ingress rules.
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 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 # 82
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. 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.
B. Import the self-signed certificates into OCI Certificates and continue using them until they expire.
C. Immediately replace the self-signed certificates on all application servers with certificates issued by OCI Certificates, without any gradual rollout.
D. Configure OCI WAF to bypass certificate validation for the legacy application.

Answer: A

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.
