Correct answer: Deploy an OCI Private Endpoint for Object Storage and configure Security Rules (NSGs) to allow traffic only to that endpoint's IP.

While a Service Gateway provides private access to all Object Storage, it is a broad gateway. OCI now supports Private Endpoints for Object Storage, which places a VNIC in your subnet. This allows for granular security controls, including NSGs, and specifically addresses the requirement to treat the storage access point as a distinct resource within the VCN network fabric, offering tighter isolation than a Service Gateway.

Correct answer: You must assign an Oracle-allocated /56 IPv6 CIDR block to the VCN during creation.

To support IPv6 in OCI, you must enable it at the VCN level. OCI provides an Oracle-allocated /56 Global Unicast IPv6 CIDR block. You cannot bring your own IPv6 range for the VCN CIDR itself (though BYOIP is available for public IPs, the VCN block is Oracle-allocated). This enables dual-stack operation.

Correct answers: A VCN Route Table in Spoke A associated with the DRG attachment, routing Spoke B's CIDR to the DRG.; A DRG Route Table associated with the Spoke A attachment that routes Spoke B's CIDR to the Hub VCN attachment.; A VCN Route Table in the Hub VCN associated with the DRG attachment, routing Spoke B's CIDR to the Firewall Private IP.

Traffic must leave Spoke A destined for Spoke B via the DRG.

When traffic from Spoke A hits the DRG, the DRG needs to know to send it to the Hub VCN (where the firewall is) rather than directly to Spoke B. This forces the traffic into the Hub.

Once traffic enters the Hub VCN from the DRG, the VCN ingress routing must direct that traffic to the Firewall's private IP instead of attempting to resolve it locally or dropping it.

Correct answer: IP Address Insights

IP Address Insights is a feature within the OCI Console that provides a comprehensive view of IP address usage across your tenancy, VCNs, and subnets. It helps identify utilization trends, potential exhaustion, and fragmentation issues.

Correct answer: FastConnect with MACsec encryption.

MACsec (Media Access Control Security) provides point-to-point encryption at Layer 2. This secures the physical link between the customer edge and the OCI edge, providing line-rate encryption suitable for high-throughput requirements like 10 Gbps, unlike IPSec which adds overhead.

Correct answer: ZPR policies are additive; traffic must be allowed by BOTH the NSG/Security List rules AND the ZPR policy to proceed.

ZPR works as an additional layer of security intent. It does not replace NSGs or Security Lists. For a packet to pass, it must be permitted by the standard network firewall rules (NSG/SL) AND explicitly authorized by a ZPR policy linking the security attributes of the source and destination.
