Traffic Direction through GWLB Endpoint:

The ingress route table directs inbound traffic to the GWLB through a GWLB endpoint (GWLBe). This endpoint is responsible for directing traffic to the Gateway Load Balancer for further processing (Option B).

GENEVE Encapsulation:

The GWLB encapsulates the inbound traffic using the GENEVE protocol. This encapsulated traffic is then sent to FortiGate instances for security inspection. The use of GENEVE ensures that the original traffic context is preserved and can be analyzed by FortiGate (Option D).

Other Options Analysis:

Option A is incorrect because GWLB does not forward traffic without encapsulation in its dedicated subnet.

Option C is incorrect as the inbound traffic is directed to the GWLB endpoint first, not directly to the application subnet.

Update Software:

As part of the AWS shared responsibility model, it is the customer's responsibility to update and maintain the software running on the EC2 instance, including applying security patches and updates (Option A).

Configure Security Groups:

Security groups act as virtual firewalls for instances to control inbound and outbound traffic. Configuring them correctly is essential for securing the EC2 instance and ensuring only legitimate traffic can reach the server (Option C).

Manage Operating System:

Managing the operating system, including user accounts, permissions, and operating system patches, is the responsibility of the customer under the shared responsibility model (Option D).

Other Options Analysis:

Option B is incorrect as changing the existing ELB to a gateway load balancer is not necessary for securing the new EC2 instance.

Option E is incorrect because it is not required to move all web servers into the same availability zone for security purposes.

Windows Firewall Blocking Traffic:

The firewall on the Windows VM might be configured to block incoming ICMP traffic (ping requests). By default, Windows Firewall is set to block ICMP traffic, which could be a reason for the connectivity issue (Option A).

Security Group Configuration:

AWS Security Groups act as virtual firewalls for instances. If there is no rule allowing ICMP traffic in the security group attached to the Windows server, the ping requests from FortiGate will be blocked. An inbound allow ICMP rule must be added to the security group to permit this traffic (Option D).

Other Options Analysis:

Option B is incorrect because the default AWS Network Access Control List (NACL) allows all inbound and outbound traffic.

Option C is incorrect as AWS does allow ICMP traffic between subnets if properly configured with Security Groups and NACLs.

AWS GuardDuty Integration:

AWS GuardDuty is a threat detection service that continuously monitors for malicious activity and unauthorized behavior to protect AWS accounts and workloads. It can generate findings that can be used to create or update firewall rules automatically in FortiGate to enhance security and provide timely protection (Option D).

Integration with FortiGate:

GuardDuty findings can be integrated with FortiGate using automation tools and scripts to create firewall rules dynamically, thereby accelerating the time-to-protection against emerging threats.

Other Options Analysis:

Option A (AWS Firewall Manager) is more suited for managing rules across multiple accounts but not for dynamic threat response.

Option B (AWS Network ACL) provides stateless filtering but does not offer automated rule creation.

Option C (SDN Connector for AWS) helps in integrating SDN capabilities but is not specifically focused on threat-based rule automation.

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.
