When configuring transitive routing with a DRG across multiple VCNs and on-premises networks, which key configuration step ensures that traffic from one VCN is correctly routed through the DRG to an on-premises destination?
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?
You are configuring a VCN with multiple subnets for a customer. The security team requires that all instances have IPv6 addresses. You configure the VCN with an IPv6 ULA CIDR block of fc00:1:1::/48 and create two private subnets. After launching instances in the two private subnets, you notice that they only have IPv4 addresses assigned. You have not manually configured any IPv6 addresses on the instances themselves. What steps are necessary to ensure the instances automatically receive IPv6 addresses?
You are designing a solution to implement IPSec encryption over a FastConnect circuit between your on- premises network and OCI. You are concerned about the overhead of IPSec impacting themaximum MTU (Maximum Transmission Unit) size that can be supported. What is the most important factor to consider when determining the MTU size for the IPSec tunnel interfaces in this scenario?
A company wants to leverage a best-of-breed approach for their application stack. They plan to use OCI for its Autonomous Database, Azure for its container orchestration (AKS), and AWS for its object storage (S3).
Considering cost optimization and minimizing data egress charges, which strategy is the MOST efficient for transferring large datasets between these services?
