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?

• A.Network Security Groups (NSGs)
• B.Route Tables
• C.Flow Logs
• D.Service Gateway

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 Dynamic Routing Gateway (DRG) connected to a FastConnect circuit.
• B.A NAT Gateway configured with public IPs for all subnets.
• C.A Service Gateway configured to access Oracle Services.
• D.An Internet Gateway configured with default route rules.

Your organization is migrating a critical three-tier application to OCI. The application requires a highly available and performant database tier. You plan to use Oracle Autonomous Database on Dedicated Exadata Infrastructure. The Autonomous Database subnet must adhere to the organization's security policy, which mandates no direct internet access and private access to other VCN subnets. You need to ensure the proper IP address allocation and routing. Which of the following procedural steps is most effective for achieving this?

• A.Create a private subnet for the Autonomous Database and configure a Service Gateway with access to only Object Storage and Yum Server Oracle Services in OCI. Configure NSG rules allowing only traffic from the application's compute instances, and configure routing to a Dynamic Routing Gateway (DRG) for access to other VCN subnets.
• B.Create a private subnet for the Autonomous Database and configure a Service Gateway with access to Autonomous Database Oracle Services in OCI. Configure NSG rules allowing only traffic from the application's compute instances, and configure routing to a Dynamic Routing Gateway (DRG) for access to other VCN subnets. Reserve a large CIDR block for future database expansion.
• C.Create a public subnet for the Autonomous Database, assign it a public IP address, and configure a Service Gateway with access to all Oracle Services in OCI. Configure routing to an Internet Gateway.
  Secure access using Security Lists allowing traffic only from approved IP ranges.
• D.Create a public subnet for the Autonomous Database and configure a Service Gateway with access to all Oracle Services in OCI. Configure NSG rules allowing only traffic from the application's compute instances.

You are designing a highly available web application on OCI. The application needs to be accessible globally with traffic being routed to the nearest region based on user location. Additionally, you need to implement sophisticated traffic management policies, such as A/B testing and weighted traffic distribution based on application version. You also require protection against DDoS attacks. Which OCI load balancing solution is best suited for these requirements?

• A.Flexible Load Balancer
• B.Regional Load Balancer
• C.Global Load Balancer with Traffic Management Steering Policies
• D.Network Load Balancer

Which OCI service facilitates the creation of a private connection between two VCNs located in different tenancies, without traversing the public internet?

• A.Remote Peering Connection (RPC)
• B.Internet Gateway
• C.Service Gateway
• D.Dynamic Routing Gateway (DRG) with Local Peering Gateway (LPG)
