Pass the Fortinet Public Cloud Security FCP_WCS_AD-7.4 Questions and answers with CertsForce

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.

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.

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.

Understanding VPC Peering:

VPC peering connections allow instances in one VPC to communicate with instances in another VPC. Peering is a one-to-one relationship between two VPCs.

Transit Routing Limitation:

AWS VPC peering connections do not support transitive peering. This means that a packet originating in VPC B cannot be routed through VPC A to reach VPC C. Each pair of VPCs must have its own peering connection.

Routing Table Configuration:

Even if you add a route in the VPC A routing table for the 192.168.0.0/16 network, it won't allow VPC B to communicate with VPC C because of the non-transitive nature of VPC peering.

Comparison with Other Options:

Option A is incorrect because adding a route in VPC A does not overcome the limitation of non-transitive peering.

Option C is incorrect because associating pcx-23232323 with VPC B is not how VPC peering works.

Option D is incorrect because you can create a separate peering connection between VPC B and VPC C, which is the required approach for communication between these VPCs.

HA Cluster in AWS Cloud:

Deploying an active-passive HA cluster in AWS requires careful consideration of the clustering protocol used to ensure seamless failover and traffic flow.

Unicast FortiGate Clustering Protocol (FGCP):

Unicast FGCP is specifically designed for environments where multicast traffic is not feasible or supported, such as in the AWS cloud. Using unicast FGCP ensures that heartbeat and synchronization traffic between the cluster members are managed correctly over unicast communication, which is suitable for AWS's network infrastructure (Option C).

Comparison with Other Options:

Option A is incorrect because while placing both cluster members in the same availability zone might be required for certain configurations, it is not the critical factor for HA formation.

Option B is incorrect as VDOM exceptions are not directly related to the successful formation of HA.

Option D is incorrect because the ELB configuration checks are more about ensuring that the load balancer correctly routes traffic but do not specifically ensure HA formation and failover.

Understanding the Requirement:

The organization needs to connect a data VPC to the on-premises infrastructure with high bandwidth.

The solution should avoid multiple connections between sites.

Transit Gateway Connect:

Transit Gateway Connect is designed to integrate with SD-WAN networks and provides scalable bandwidth using GRE tunnels.

It simplifies hybrid cloud connectivity by allowing high bandwidth connections without the need for multiple physical connections.

Benefits of Transit Gateway Connect:

Supports scalable bandwidth through GRE tunnels.

Facilitates seamless integration with on-premises and cloud environments.

Reduces complexity by avoiding the need for multiple VPN connections.

Comparison with Other Options:

Option A (Transit VPC with IPSec) is not preferred due to complexity and potential limitations in bandwidth scalability.

Option B (Internet Gateway) is not suitable for private, high-bandwidth connections.

Option C (Transit Gateway multicast) does not address the requirement for high bandwidth in a hybrid cloud setup.

Implicit Deny Rule:

Similar to traditional firewall rule sets, FortiGate Cloud-Native Firewall (CNF) includes an implicit deny rule at the bottom of each policy set. This means any traffic that does not match an existing rule in the policy set is automatically denied (Option A).

Policy Set Creation:

When a new CNF instance is deployed, a new policy set is created specifically for that instance. This ensures that each CNF instance can have a tailored set of security policies based on the specific needs of the deployment (Option C).

Other Options Analysis:

Option B is incorrect because policy sets do not require manual synchronization; they are applied automatically once configured.

Option D is incorrect as a single CNF instance operates with a single policy set at a time.

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.

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.

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.
