FortiGate Cloud-Native Firewall (CNF):

FortiGate CNF offers cloud-native firewall capabilities designed to provide network security within AWS. It integrates seamlessly with AWS services and offers advanced threat protection and traffic management (Option C).

Fortinet Managed Rules for AWS WAF:

Fortinet Managed Rules for AWS WAF provide pre-configured, updated security rules that protect web applications from common threats such as SQL injection and cross-site scripting. This offering simplifies the protection of web applications hosted on AWS (Option D).

FortiWeb Cloud:

FortiWeb Cloud is a Web Application Firewall (WAF) as a service that provides comprehensive protection for web applications hosted on AWS. It offers features such as bot mitigation, DDoS protection, and deep inspection of HTTP/HTTPS traffic (Option E).

Comparison with Other Options:

Option A (AWS WAF) is a native AWS service, not a Fortinet offering.

Option B (FortiEDR) is focused on endpoint detection and response, which is not specifically aimed at protecting web applications.

Cluster Elastic IP Address (EIP) Movement:

During a failover in an active-passive (A-P) cluster, the Elastic IP (EIP) associated with the active FortiGate instance (FGT-1) needs to be moved to the passive instance (FGT-2), which becomes the new active instance. This ensures that the traffic directed to the EIP is now handled by FGT-2 (Option A).

Secondary IP Address Movement:

The secondary IP address on Port2 of the current active instance (FGT-1) is moved to the same port on the new active instance (FGT-2). This step is crucial to ensure seamless network traffic redirection and connectivity for the services relying on that IP address (Option B).

Other Options Analysis:

Option C is incorrect because the static route modification mentioned is not directly related to the failover process described.

Option D is incorrect because no additional route needs to be added to the HA Sync AZ2 subnet route table to forward traffic to the Internet Gateway during a failover.

Understanding Transit Gateway Connect:

Transit Gateway Connect is a feature of AWS Transit Gateway that simplifies the integration of SD-WAN networks with AWS. It uses Generic Routing Encapsulation (GRE) tunnels to facilitate this connection.

GRE Tunnels and Bandwidth:

GRE tunnels can dynamically scale to meet increasing bandwidth demands. They allow multiple tunnels between the same endpoints, which can aggregate bandwidth without requiring additional configuration.

Scaling Bandwidth with GRE:

The GRE protocol used by Transit Gateway Connect can support high bandwidth requirements by spreading traffic across multiple tunnels. As demand grows, additional tunnels can be automatically used to handle the increased traffic load.

Comparison with Other Options:

Option A suggests using public IP addresses, which is not relevant to bandwidth scaling.

Option B is incorrect because bandwidth can be increased through GRE scaling.

Option D suggests adding a Transit VPC, which is unnecessary for increasing bandwidth when using Transit Gateway Connect.

Zero-day Protection:

FortiWeb VM provides robust protection against zero-day vulnerabilities through advanced security mechanisms and frequent updates from FortiGuard. This ensures that web applications are protected from newly discovered threats that have not yet been patched or recognized by other security systems (Option C).

Advanced WAF Functionality:

FortiWeb VM offers a range of advanced WAF features that go beyond what is typically provided by managed rules for AWS WAF. These include more detailed traffic analysis, customizable rules, machine learning-based threat detection, and comprehensive logging and reporting capabilities (Option D).

Other Options Analysis:

Option A is more relevant to a consumption-based pricing model but not a specific benefit unique to FortiWeb VM over AWS WAF.

Option B is incorrect because both FortiWeb VM and Fortinet Managed Rules for AWS WAF are powered by FortiGuard updates.

Instance Metadata Traffic:

VPC flow logs do not capture traffic to and from the link-local address 169.254.169.254, which is used for accessing instance metadata (Option A).

DHCP Traffic:

DHCP traffic is not captured by VPC flow logs. This is because DHCP relies on broadcast and multicast traffic, which is excluded from flow logs (Option B).

Security Monitoring:

VPC flow logs can be used as a security tool to monitor the traffic that is reaching the instances. By analyzing the flow logs, administrators can detect suspicious activities and troubleshoot connectivity issues (Option D).

Other Considerations:

Option C is incorrect because flow logs do capture traffic to the reserved IP address of the default VPC router.

Option E is incorrect as VPC flow logs do not provide real-time log streams but rather capture data at intervals and deliver them to CloudWatch or S3.

Understanding Gateway Load Balancer (GWLB):

GWLB is designed to distribute traffic across multiple appliances for both inbound and outbound traffic, providing scalability and high availability.

Traffic Load Balancing:

GWLB can send traffic to multiple FortiGate appliances for load balancing purposes, ensuring efficient use of resources (Option A).

Stateful Processing:

For stateful processing, GWLB ensures that traffic flows (both inbound and outbound) for a given connection are directed to the same FortiGate appliance. This maintains session integrity (Option B).

Preservation and Hashing of Traffic:

Options C and D are incorrect as they suggest incorrect behavior regarding traffic content preservation and hashing for data integrity, which are not primary functions of GWLB.

Internet Gateway Requirement:

For an Elastic IP (EIP) to be assigned to an instance's primary ENI, the VPC must have an Internet Gateway (IGW) attached. The IGW enables the VPC to communicate with the internet, allowing the EIP to function properly (Option C).

Process of Assigning EIP:

Once the Internet Gateway is attached to the VPC, the EIP can be successfully assigned to the primary ENI of the FortiGate VM, providing it with internet access.

Other Options Analysis:

Option A is incorrect because the primary ENI is already in a public subnet.

Option B is not necessary and may not solve the issue without an attached Internet Gateway.

Option D is partially correct about the routing table but does not address the primary issue of needing an Internet Gateway.

Enhanced Redundancy:

Deploying an active-passive (A-P) FortiGate cluster across two availability zones (AZs) provides enhanced redundancy by ensuring that if one AZ fails, the other can take over, maintaining high availability and uptime.

IP Addressing and Subnetting:

One of the major differences when deploying across different AZs compared to the same AZ is that IP addressing and subnetting are not shared between the instances. Each AZ operates independently with its own set of subnets and IP addresses, which must be managed separately (Option D).

Other Options Analysis:

Option A is incorrect because the FortiGate devices in an A-P setup do not act as a single logical instance; they operate in a failover setup.

Option B is incorrect because secondary IP address configuration is used in both single AZ and multi-AZ deployments.

Option C is incorrect because the number of subnets required is typically more when deploying across multiple AZs for redundancy.

Scalability:

FortiGate Cloud-Native Firewall (CNF) is designed to scale seamlessly with your cloud infrastructure, providing the necessary protection without requiring manual intervention for scaling (Option B).

Firewall-as-a-Service:

FortiGate CNF is offered as a Firewall-as-a-Service (FWaaS), which simplifies the deployment and management of firewall capabilities directly in the cloud environment (Option D).

Management:

FortiGate CNF can be managed using FortiManager and AWS Firewall Manager, providing comprehensive management capabilities both from Fortinet's platform and AWS's native management tools (Option E).

Other Considerations:

Option A (carrier-grade protection) is not specifically highlighted as a feature of FortiGate CNF.

Option C (uses AWS Elastic Load Balancing) is incorrect as FortiGate CNF operates independently of AWS ELB, although it can integrate with various AWS services.

Remote Access to FortiGate VM:

The FortiCloud portal allows users to remotely access their FortiGate VM instances. This is particularly useful for managing and configuring instances without needing direct network access (Option A).

FortiFlex Portal Access:

The FortiFlex portal is a feature that becomes available only after purchasing a FortiFlex license and registering it on FortiCare. This portal provides additional functionalities and services related to FortiFlex (Option C).

IAM Permissions:

Option B is incorrect because the Identity and Access Management (IAM) permissions in the FortiCloud portal do not require writing JSON scripts; they can be managed through the portal interface.

Subscription to Cloud Services:

Option D is incorrect because FortiCloud provides access to services beyond those subscribed through the AWS marketplace, including services directly offered by Fortinet.
