Fortinet NSE6_WCS-7.0 Practice Test - Questions Answers, Page 2

Dynamic Address Object Update:

The debug output shows that the IP address of the AWS Windows Server Lab has been updated automatically, indicating that the dynamic address object feature is working as intended. This allows FortiGate to adapt to changes in the IP addresses of AWS instances dynamically (Option A).

SDN Connector Configuration:

The messages in the debug output confirm that the SDN connector is able to retrieve instance information and update the firewall address objects successfully. This implies that the SDN connector is correctly configured and has the necessary permissions (Option C).

Manual Change and Permissions:

Option B is incorrect because while the address object could theoretically be changed manually, this is not inferred from the debug output.

Option D is incorrect because the debug output does not indicate that the AWS user account must have full administrative rights. The required permissions are typically more scoped to specific actions related to SDN.

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.

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.

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.

Invalid Credentials:

The debug output shows an 'AuthFailure' error, indicating that AWS was not able to validate the provided access credentials. This usually points to incorrect or invalid AWS access or secret keys configured in the AWS Lab SDN connector (Option C).

Clock Skew:

Another common reason for authentication failures in AWS API calls is a clock skew between the FortiGate device and AWS. AWS requires that the system time of the client making the API call is synchronized with its own time, within a small margin. If there is a significant time difference, AWS will reject the credentials (Option B).

Other Options Analysis:

Option A is incorrect because the AWS API supports XML version 1.0.

Option D is incorrect as the error message does not indicate an issue with connecting on port 401.

Option E is incorrect because the error is related to authentication, not the absence of instances.

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.

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.

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.

GENEVE Protocol Overview: GENEVE Protocol

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.
