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?

• A.Attaching each VCN to a separate DRG and configuring static routing between them.
• B.Using a centralized DRG route table with route distribution enabled.
• C.Manually updating static routes in each VCN's route table.
• D.Implementing a Service Gateway to broadcast route updates.

When migrating workloads to OCI requiring consistent, high-bandwidth connections with minimal latency, and your on-premises data center has direct fiber connectivity, which OCI service is most suitable?

• A.Dynamic Routing Gateway (DRG) with remote peering
• B.Internet Gateway
• C.FastConnect Colocation with Oracle
• D.Site-to-Site VPN

When migrating workloads from another cloud provider to OCI, what is a key consideration when choosing a connectivity strategy to ensure optimal network performance?

• A.Ignoring the geographical proximity of the cloud regions being interconnected
• B.Factoring in the bandwidth requirements of the applications being migrated and choosing a connection that can accommodate peak traffic loads
• C.Prioritizing the lowest possible initial setup cost, even if it results in higher ongoing operational expenses
• D.Only considering managed connectivity solutions to avoid the complexity of configuring VPNs or direct interconnects

Your organization is migrating a legacy application to OCI. This application relies on a specific IP address for its external communication, and you need to maintain this IP address during the migration. Which OCI Load Balancer feature or configuration can help you achieve this while ensuring high availability for the application?

• A.Deploying multiple Flexible Load Balancers with different public IP addresses and using DNS round- robin.
• B.Using a private IP address for the load balancer and NAT Gateway for outbound traffic.
• C.Utilizing the Network Load Balancer (NLB) with its inherent ability to preserve client IP addresses.
• D.Configuring the Flexible Load Balancer with a reserved public IP address.

You are a Cloud Architect troubleshooting connectivity issues in your OCI environment. Your application servers, residing in private subnets within a VCN, need to access Object Storage within the same region to retrieve critical data. You have confirmed that there are no NSG rules blocking traffic between the subnets.
However, the instances cannot access Object Storage. You have a Service Gateway configured, and route rules in the private subnets directing traffic for Oracle Services to the Service Gateway. What is the most likely cause of this issue?

• A.The security list associated with the private subnet does not allow outbound traffic to all Oracle Services.
• B.The NAT Gateway is not configured correctly to access external services.
• C.The Service Gateway is not configured with the correct service CIDR labels for Object Storage in the region.
• D.The Internet Gateway is disabled.
