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

You have deployed a distributed application across OCI and Azure. You have established the OCI-Azure Interconnect. You are experiencing packet loss and performance degradation when transmitting large volumes of data between the two cloud providers. You have verified that the network devices on both sides are correctly configured. Which is NOT a typical root cause to investigate when troubleshooting performance issues across the OCI-Azure Interconnect?

You are designing a hybrid cloud environment where multiple VCNs in OCI need to communicate with your on-premises network. You are using a single Dynamic Routing Gateway (DRG) to connect to your on- premises network via FastConnect. You want to ensure that each VCN is isolated from the others and that traffic between VCNs must pass through your on-premises security appliances for inspection. How should you configure the DRG attachments and route tables to enforce this security policy?

When analyzing Flow Logs for a subnet, how can you filter logs to isolate traffic that was rejected due to a specific security list rule?

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?

In a complex multi-region OCI environment using DRGs for transitive routing, which method is most efficient for ensuring that route updates from on-premises networks are propagated to all connected VCNs?

Which OCI service or feature is best suited for capturing and analyzing network traffic metadata to identify anomalies and troubleshoot connectivity issues between VCN resources?

You are responsible for maintaining the network connectivity between OCI and Azure using the OCI-Azure Interconnect. You need to perform planned maintenance on your on-premises network, which will temporarily disrupt the BGP (Border Gateway Protocol) sessions between your on-premises network and both OCI and Azure. You want to ensure that traffic between OCI and Azure continues to flow without interruption during the maintenance window. Which action is MOST important to take before starting the maintenance to ensure continuous connectivity between OCI and Azure?

In a multi-tier architecture with multiple application instances across different private subnets, which Bastion service approach minimizes the need for continuous maintenance of individual session configurations?
