Which OCI logging feature allows you to correlate network traffic patterns from Flow Logs with application-level events from Service Logs for comprehensive troubleshooting?
You are designing a multicloud architecture where your customer wants to leverage OCI for its cost-effective compute and storage, while utilizing Microsoft Azure’s AI/ML services and AWS’s extensive serverless capabilities. The application requires low latency and high bandwidth between the clouds. Which of the following approaches provides the LEAST optimal solution for interconnecting these three cloud providers for production workloads?
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 have configured an IPSec VPN tunnel over your FastConnect circuit to OCI. You are experiencing intermittent connectivity issues and notice that the VPN tunnel is flapping (frequently going up and down). You have verified the IKE and IPSec configuration and confirmed that the security policies are correct. Which is a LESS likely cause of the VPN tunnel flapping when using IPSec over FastConnect, compared to using IPSec over the public internet?
Which OCI service provides detailed logs for network traffic traversing a Network Load Balancer, offering insights into client connections and backend health checks?
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?
When configuring transitive routing through a network appliance in a hub-and-spoke VCN topology, which configuration is necessary to ensure that traffic from a spoke VCN to another spoke VCN passes through the network appliance?
Your organization is migrating workloads to a multicloud environment using OCI, AWS, and Azure. You have applications that require access to on-premises resources and must maintain high security standards. Which connectivity configuration would provide the MOST secure and reliable access while adhering to best practices for a hybrid multicloud architecture?
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 managing the network infrastructure of a multi-tenant SaaS application deployed on OCI. Each tenant has their own dedicated VCN. To simplify management and provide a centralized point for connectivity to your on-premises network via FastConnect, you are using a DRG. However, you need to ensure that tenants are logically isolated from each other, and no traffic can flow directly between tenant VCNs through the DRG. How can you achieve tenant isolation while still allowing each tenant to connect to your on-premises network through the centralized DRG?
