NSE6_WCS-7.0 Exam Dumps - Fortinet NSE 6 - Cloud Security 7.0 for AWS

Load Balancer Configuration Overview:

The provided configuration indicates that the ELB is an internet-facing load balancer.

Multi-AZ Load Balancing:

The load balancer is configured to distribute traffic across multiple availability zones (A, B, and C), ensuring high availability and fault tolerance (Option A).

Accessing Targets via DNS:

The DNS name of the load balancer (LabELB-716e15332f6401f8.elb.us-east-2.amazonaws.com) can be used to reach the targets behind the ELB, facilitating traffic routing to the appropriate instances (Option C).

Comparison with Other Options:

Option B is incorrect as the ARN is not used to access the load balancer directly.

Option D is incorrect because the load balancer is configured for internet-facing traffic, not just internal VPC traffic.

SSL Inspection Requirement:

FortiWeb Cloud provides comprehensive SSL inspection capabilities, allowing it to decrypt and inspect HTTPS traffic for threats. This is a crucial feature for many organizations that need to ensure all traffic, including encrypted traffic, is thoroughly inspected (Option C).

Comparison with AWS WAF:

While AWS WAF with Fortinet managed rules provides robust protection, it might not offer the same level of SSL inspection capabilities as FortiWeb Cloud.

Other Considerations:

Option A (Manual WAF signature updates) is incorrect because FortiWeb Cloud updates signatures automatically.

Option B (PCI 6.6 compliance) is a general requirement for any WAF solution, not specific to choosing FortiWeb Cloud over AWS WAF.

Option D (Traffic inspection for malware) is a feature provided by both FortiWeb Cloud and AWS WAF with Fortinet managed rules.

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.

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.
