A financial services company is implementing a multicloud strategy, storing sensitive customer data in OCI due to its enhanced security features, running analytics workloads in AWS, and utilizing a SaaS application hosted in Google Cloud Platform (GCP). To comply with stringent data sovereignty regulations, the company requires that all traffic between OCI and AWS must transit exclusively within the United States. Which is the MOST critical consideration when choosing a connectivity solution to ensure compliance?

• A. Using the native OCI Dynamic Routing Gateway (DRG) and AWS Virtual Private Gateway (VGW) with IPSec VPNs, as this automatically ensures traffic stays within the specified region
• B. Leveraging public internet-based connectivity with geographically restricted DNS resolution to limit traffic outside the US
• C. Using a generic VPN tunnel between OCI and AWS, ensuring both gateways are located within US regions
• D. Selecting a FastConnect partner who can guarantee that all OCI-AWS traffic will stay within the United States geographic boundary

In a multi-tier application architecture with separate public and private subnets, where should an OCI Bastion host be placed to provide secure access to resources in the private subnets without exposing them to the internet?

• A. Behind an Internet Gateway in the public subnet.
• B. In a separate VCN peered with the application VCN.
• C. Directly in the private subnet.
• D. In a dedicated public subnet specifically for Bastion hosts.

You have successfully enabled DNSSEC on your OCI DNS zone and provided the DS record to your domain registrar. However, when you test your DNS configuration using online DNSSEC validation tools, you are still seeing errors indicating that DNSSEC validation is failing. What is the most likely reason for this failure?

• A. The OCI DNS resolver is not configured to validate DNSSEC signatures.
• B. The Time To Live (TTL) value for your DNS records is too low, causing validation errors.
• C. The DNSSEC algorithm used by OCI DNS is not supported by the validation tools.
• D. The domain registrar has not yet published the DS record in the parent zone, preventing the chain of trust from being established.

You are setting up a FastConnect connection between your on-premises data center and OCI. You need to configure BGP to exchange routing information. You require OCI to always prefer the FastConnect path for traffic destined to your on-premises network, even if OCI learns about the same prefixes via the public internet. Which BGP attribute should you configure on the OCI side of the FastConnect connection to achieve this?

• A. Configure MED to a lower value for routes advertised via FastConnect.
• B. Decrease the AS Path length for routes learned via FastConnect.
• C. Increase the Local Preference for routes learned via FastConnect.
• D. Advertise a more specific (longer prefix length) route via FastConnect.

Your security policy mandates that all communication between your compute instances in a private subnet and OCI Object Storage must be authenticated and authorized using IAM policies and not rely on public IP addresses. Which OCI networking feature is the most appropriate to satisfy this requirement?

• A. Private Subnet with a NAT Gateway and IAM rules.
• B. Public Subnet with a Network Firewall and IAM rules.
• C. Public Subnet with an Internet Gateway and IAM rules.
• D. Private Subnet with a Service Gateway and IAM rules.
