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

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.

Symmetric Traffic Flow with SNAT:

In active-active (A-A) clusters, symmetric traffic flow is essential for maintaining session integrity across multiple instances. Source Network Address Translation (SNAT) is performed inbound to ensure that return traffic is routed correctly (Option A).

Load Balancer Requirement:

A-A clusters require a load balancer to distribute incoming traffic evenly across the active instances. This is crucial for balancing the load and providing high availability (Option C).

API Calls and Failovers:

Option B is incorrect because failovers in A-A clusters do not typically rely on API calls but are managed by the load balancer and the clustering mechanism itself.

Software-Defined Network (SDN) Failover:

Option D is incorrect as SDN is not specifically required for performing failovers in A-A clusters. The failover mechanism is typically managed by the load balancer and FortiGate's clustering technology.

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.

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.

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.

FortiSandbox Deployment:

FortiSandbox for AWS deploys new EC2 instances to create isolated environments where it can safely execute and analyze suspicious files. These instances run custom Windows and Linux virtual machines specifically configured for sandboxing (Option D).

Sandboxing Process:

The process involves sending potential malware to these isolated VMs, executing it, and monitoring its behavior to detect malicious activities. The results are then captured and analyzed to provide detailed threat intelligence.

Other Options Analysis:

Option A is incorrect because FortiSandbox for AWS operates entirely within the AWS environment and does not require an on-premises manager.

Option B is incorrect as the FortiSandbox manager is not installed on the AWS platform for managing on-premises instances.

Option C is incorrect because FortiSandbox requires sufficient resources to perform the actual sandboxing and analysis tasks.

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.

HA Event and Failover:

The debug output indicates that a failover event occurred and the secondary instance (Fgt2) is now taking over as the master.

Elastic IP Association:

The debug output shows the process of moving the Elastic IP (eipalloc-090425f83f912c8d6) to the new master instance. This involves associating the Elastic IP with the appropriate network interface (eni) of the new master.

Specific IP Address Association:

The Elastic IP is specifically associated with port1 of Fgt2. The message "associate elastic ip eipalloc-090425f83f912c8d6 to 10.0.0.13 of eni eni-0f6b35f8fccd24eb0" indicates that the Elastic IP is now linked to the primary IP address (10.0.0.13) on port1 of the new master.

Other Options Analysis:

Option A is incorrect because the routing table update details are not explicitly stated.

Option C is incorrect because the IP address association mentioned relates to an Elastic IP, not eni-0b61d8afc0aefb8a2.

Option D is incorrect because it specifically mentions port2 for the Elastic IP association, which is not indicated in the debug output.

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.

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.
