Oracle Cloud Infrastructure 2025 Networking Professional - 1z0-1124-25 Exam Practice Test

A large financial institution is migrating its on-premises trading platform to OCI. The platform requires low latency and high bandwidth connectivity to the on-premises data center. You have established an Oracle Cloud Infrastructure FastConnect circuit. You now need to connect multiple VCNs in different regions to the on-premises data center via this FastConnect circuit, optimizing for cost and management overhead. Which DRG configuration would be the most efficient and recommended approach?

You are designing an OCI networking architecture for a multi-tier application using Infrastructure as Code (IaC). The architecture includes an OKE cluster for the front-end, a set of Compute instances for the back- end, and an Autonomous Database. You want to ensure that all traffic between these components is encrypted. You are using Transport Layer Security (TLS) for end-to-end encryption but are concerned about the overhead of encrypting all traffic within the VCN. Which approach provides the MOST balanced approach to security and performance, minimizing the overhead of encryption while still protecting sensitive data?

You are designing a hybrid cloud solution where sensitive data must be transferred between your on-premises data center and an OCI VCN. You require a dedicated, private connection with guaranteed bandwidth and low latency. In addition to FastConnect, what additional product would you implement to achieve encryption of the traffic traversing the FastConnect link and to ensure data confidentiality?

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?

In a multi-region OCI environment, which configuration is necessary to allow communication between two VCNs located in different regions through a DRG?

For a migration scenario where on-premises workloads need to access OCI Object Storage for large data transfers, and a dedicated, private connection is required, which OCI service best fulfills this need?

You are designing a multi-tier application in OCI, deploying the application tier in a public subnet and the database tier in a private subnet within the same VCN. The application tier requires access to specific external internet resources for software updates and third-party API calls. However, the database tier should not have direct internet access. Which of the following is the most secure and efficient method to achieve this configuration?

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?
