Fortinet Updated NSE6_WCS-7.0 Exam Questions and Answers by mylo

Understanding the Architecture:

The architecture includes an EC2 instance in a private subnet, a Gateway Load Balancer Endpoint (GWLBe), a NAT Gateway (NAT GW), and an Internet Gateway (IGW).

Route Tables and Routing:

The private route table for the subnet containing the EC2 instance has a route pointing to the GWLBe for internet-bound traffic.

The public route table for the subnet containing the NAT Gateway has routes to the IGW.

Traffic Flow Analysis:

Traffic initiated from the EC2 instance destined for the internet will first be routed to the GWLBe as per the private route table.

The GWLBe will forward the traffic to the NAT Gateway.

The NAT Gateway will then route the traffic to the IGW, which finally sends the traffic to the internet.

Comparison with Other Options:

Option A suggests direct routing to the NAT GW from the EC2 instance, which is incorrect.

Option B incorrectly states there is no route to the internet in the private route table.

Option D suggests direct routing from GWLBe to the internet, which is not the case.

Dynamic Address Object Update:

The debug output shows that the IP address of the AWS Windows Server Lab has been updated automatically, indicating that the dynamic address object feature is working as intended. This allows FortiGate to adapt to changes in the IP addresses of AWS instances dynamically (Option A).

SDN Connector Configuration:

The messages in the debug output confirm that the SDN connector is able to retrieve instance information and update the firewall address objects successfully. This implies that the SDN connector is correctly configured and has the necessary permissions (Option C).

Manual Change and Permissions:

Option B is incorrect because while the address object could theoretically be changed manually, this is not inferred from the debug output.

Option D is incorrect because the debug output does not indicate that the AWS user account must have full administrative rights. The required permissions are typically more scoped to specific actions related to SDN.

Web Filtering:

FortiGate for AWS offers advanced web filtering capabilities, which allow organizations to control and monitor web access. This feature complements AWS's native security services by providing granular control over web traffic (Option B).

OSPF over IPSec:

FortiGate for AWS can establish dynamic routing protocols such as OSPF (Open Shortest Path First) over IPSec tunnels. This capability enhances network routing flexibility and security, which is not natively provided by AWS (Option C).

Secure SD-WAN with Application Visibility:

FortiGate for AWS provides Secure SD-WAN functionality, offering enhanced application visibility and traffic management. This is a significant addition to AWS's networking services, optimizing application performance and security (Option E).

Comparison with Other Options:

Option A (Higher VPN throughput) is not specifically enhanced by FortiGate as compared to AWS native services.

Option D (Advanced dynamic routing) is partially covered under OSPF over IPSec but is not as specific as the other chosen options.
