Free Practice Questions for Fortinet NSE6_WCS-7.0 Exam

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.

Same Region Deployment:

Deploying FortiWeb Cloud in the same AWS region as your web application minimizes latency and ensures faster response times by reducing the distance data needs to travel (Option A).

Content Delivery Network (CDN):

Enabling a CDN can significantly improve response times by caching content closer to the end-users, reducing the load on the origin server, and speeding up content delivery (Option B).

Other Options Analysis:

Option C is incorrect because modifying DNS entries to directly point to your web server bypasses the WAF protection, which is not advisable for security reasons.

Option D is incorrect because disabling WAF functionality would expose your web application to vulnerabilities and threats, compromising security.

VPC-Scoped Protection:

When deploying a FortiWeb VM inside a Virtual Private Cloud (VPC), the security and protection it offers are limited to the applications and traffic that pass through that specific VPC. This means that any applications outside this VPC will not benefit from the protection of FortiWeb VM (Option D).

Comparison with FortiWeb Cloud:

FortiWeb Cloud, being a cloud-native WAF-as-a-Service, can protect applications regardless of their VPC location, offering broader and more flexible protection capabilities.

Other Options Analysis:

Option A is incorrect because both FortiWeb VM and FortiWeb Cloud protect against OWASP Top 10 threats.

Option B is incorrect because FortiWeb VM does support zero-day protection.

Option C is incorrect as the performance of FortiWeb VM in applying advanced WAF protection is not inherently slower compared to FortiWeb Cloud.

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.

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.

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.

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.

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.

DNS Configuration:

For FortiWeb Cloud to effectively protect web applications, the DNS records for the application servers must be configured to point to FortiWeb Cloud. This ensures that all incoming traffic is routed through FortiWeb Cloud for inspection and protection (Option A).

Traffic Filtering:

FortiWeb Cloud provides robust protection by filtering incoming traffic to block the OWASP Top 10 attacks, zero-day threats, and other application layer attacks. This ensures the security and integrity of the web applications it protects (Option B).

Other Options Analysis:

Option C is incorrect because FortiWeb Cloud can protect application servers across different VPCs or regions, not just within the same VPC.

Option D is incorrect because step 2 does not require an AWS S3 bucket; it refers to the inspection and filtering of incoming traffic.
