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

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 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.

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.
