In a Zero Trust network architecture, what is the primary purpose of implementing micro-segmentation within OCI VCNs?
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?
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?
Your company is migrating its on-premises data center to OCI. A critical security requirement is to maintain centralized logging and auditing of all network traffic traversing the OCI Network Firewall. You need to ensure that every session that passes through the firewall is logged and can be analyzed for security events. Which OCI service should you configure in conjunction with the Network Firewall to achieve this centralized logging?
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?
You are designing an OCI VCN for a new application with the following requirements: The application servers in a private subnet must be able to download software updates from public repositories on the internet; the application servers must NOT be directly accessible from the public internet; the application servers must also be able to access Oracle Cloud Infrastructure Registry (OCIR) within the same region to pull container images. Which combination of VCN Gateways BEST meets these requirements?
When establishing cross-tenancy connectivity using Remote Peering Connections (RPCs), which IAM policy statement is essential to grant the requesting tenancy the ability to initiate the connection?
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?
Your company requires a dedicated, high-bandwidth, and low-latency connection between your on-premises data center and your OCI tenancy. You need to connect to OCI in a region where Oracle is not directly present with a FastConnect location. You also want to leverage a third-party network provider for this connectivity. Which FastConnect connectivity model would be the most suitablefor your requirements?
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?
