Oracle Cloud Infrastructure 2025 Networking Professional

Question 1

You are designing a highly available and scalable e-commerce application on OCI. The application requires load balancing for both HTTP/HTTPS traffic and TCP-based microservices communication. You need a solution that provides advanced traffic management capabilities, including content-based routing and path- based routing, and can also protect against common web exploits. Which OCI load balancing offering is the most suitable for this scenario, considering the need for web application firewall (WAF) integration?

A. Network Load Balancer

B. Load Balancing as a Service (LBaaS)

C. Application Load Balancer

D. Flexible Load Balancer

Question 2

You are designing an OCI architecture where a custom application running on a compute instance in a private subnet needs to securely access an Oracle Integration Cloud (OIC) instance. The security policy mandates that all communication remains within the OCI network and avoids traversing the public internet. Which type of endpoint provides the most secure and direct connectivity for this scenario?

A. Regional Endpoint

B. Public Endpoint

C. Service Gateway Endpoint

D. Private Endpoint

Question 3

Your company uses OCI Certificates to manage SSL/TLS certificates for its public-facing applications. You need to implement a solution that automatically renews these certificates before they expire to avoid service disruptions. Which OCI Certificates feature or configuration best achieves this?

A. There is no automatic renewal feature in OCI Certificates; manual renewal is always required.

B. Enable "Automatic Renewal" option within the OCI Certificates service and ensure DNS validation is properly configured.

C. Manually renew the certificates through the OCI Console before their expiration date.

D. Use OCI Vault to store the certificates and manually renew them using the Vault API.

Question 4

Your company utilizes a hybrid cloud architecture, connecting its on-premises network to an OCIVCN using a FastConnect private peering connection. You need to ensure that instances within a specific subnet in the VCN can only communicate with resources in a designated IP address range within the on-premises network.
What is the MOST effective way to achieve this specific network isolation?

A. Modify the VCN's default security list to restrict traffic to the on-premises IP address range.

B. Create a custom route table for the subnet with a route rule pointing to the Dynamic Routing Gateway (DRG) and configure network security groups (NSGs) to limit traffic to the specified on-premises IP address range.

C. Configure an Internet Gateway for the subnet with a route rule to the on-premises network.

D. Configure a Local Peering Gateway (LPG) for the subnet to route traffic to the on-premises network.

Question 5

You are a Network Engineer designing a hybrid cloud architecture for a large enterprise. The company requires secure and private connectivity between their on-premises network and their OCI VCN. They have sensitive data that cannot traverse the public internet. Which OCI VCN gateway is most appropriate for establishing this connection, ensuring end-to-end data encryption and isolation from the public internet?

A. A NAT Gateway configured with public IPs for all subnets.

B. An Internet Gateway configured with default route rules.

C. A Dynamic Routing Gateway (DRG) connected to a FastConnect circuit.

D. A Service Gateway configured to access Oracle Services.

Question 6

You are setting up a FastConnect connection between your on-premises data center and OCI. You need to configure BGP to exchange routing information. You require OCI to always prefer the FastConnect path for traffic destined to your on-premises network, even if OCI learns about the same prefixes via the public internet. Which BGP attribute should you configure on the OCI side of the FastConnect connection to achieve this?

A. Decrease the AS Path length for routes learned via FastConnect.

B. Advertise a more specific (longer prefix length) route via FastConnect.

C. Configure MED to a lower value for routes advertised via FastConnect.

D. Increase the Local Preference for routes learned via FastConnect.

Question 7

In a hybrid cloud migration, which OCI component is essential for dynamically routing traffic between on- premises networks and OCI Virtual Cloud Networks (VCNs), facilitating seamless communication?

A. Local Peering Gateway (LPG)

B. Dynamic Routing Gateway (DRG)

C. Service Gateway

D. Internet Gateway
