Your organization is migrating a high-compliance workload to OCI. You have established a FastConnect connection using a third-party provider. The security policy mandates that ALL traffic traversing the FastConnect circuit must be encrypted at Layer 3, regardless of the physical circuit security. Which solution should you implement?
Show answer details
Correct answer: B
OCI supports running IPSec VPN tunnels over a FastConnect virtual circuit. This provides Layer 3 encryption for the data traversing the dedicated private line, satisfying the requirement for encryption 'regardless of physical circuit security' and ensuring end-to-end encryption at the network layer.

An administrator needs to troubleshoot a connectivity issue between two OCI instances in different VCNs connected via a DRG. They want to visualize the hop-by-hop path and identify exactly which security rule or route table is blocking the traffic. Which OCI Network troubleshooting tool provides this specific analysis?
Show answer details
Correct answer: B
Network Path Analyzer (NPA) uses a synthetic traffic analysis (based on configuration, not actual packets) to determine if a path exists between source and destination. It explicitly details hop-by-hop routing and security rule evaluation, pinpointing exactly which Security List, NSG, or Route Table entry is causing a drop.
- 3
A customer is configuring the OCI Network Firewall to inspect traffic. They want to inspect traffic that is encapsulated in a specific tunnel protocol. Which new capability of the OCI Network Firewall (introduced for 2025) supports this requirement?
Show answer details
Correct answer: A
OCI Network Firewall has added support for Tunnel Inspection, specifically allowing it to inspect traffic encapsulated in protocols like VXLAN. This allows the firewall to look 'inside' the tunnel packets to apply security policies to the inner payload.

You are designing a multi-cloud architecture connecting OCI and Google Cloud Platform (GCP). You need the lowest latency and highest reliability connection between the two clouds without using an intermediate carrier or the public internet. Which connectivity option should you choose?
Show answer details
Correct answer: B
Oracle and Google have established a direct interconnection partnership (similar to the Oracle-Azure Interconnect). This allows for direct, low-latency private connectivity between OCI FastConnect and Google Cloud Interconnect in supported regions, without intermediate providers.
- 5
A multinational financial institution is designing a new OCI network architecture. They require a dedicated connection to OCI Object Storage for their private subnets without traversing the public internet. However, their security compliance team mandates that access must be granted only to a specific Object Storage bucket, not the entire service. Which implementation meets this requirement?
Show answer details
Correct answer: B
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.
- 6
You are consulting for a client migrating a legacy application to OCI. The application uses hardcoded IPv4 addresses for internal communication. You need to design a VCN structure that supports this legacy requirement while preparing for a future IPv6 migration. The VCN must support dual-stack connectivity for all resources. Which configuration step is mandatory during the VCN creation?
Show answer details
Correct answer: A
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.
