Fortinet NSE6_WCS-7.0 Dumps

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.

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.

Network Load Balancer:

Deploying a network load balancer ensures that incoming traffic is distributed across multiple web servers, providing high availability and redundancy. This setup helps in managing traffic efficiently and maintaining service uptime even if some servers fail (Option A).

Multiple Availability Zones:

Deploying web servers in multiple availability zones (AZs) enhances fault tolerance and availability. If one AZ goes down, servers in other AZs can continue to handle the traffic, ensuring the web application remains accessible (Option D).

Other Options Analysis:

Option B is incorrect because NAT Gateways are used to provide internet access to instances in private subnets, not to make private addresses reachable from the internet.

Option C is not sufficient on its own for high availability. Adding a route to the default VPC route table forwarding traffic to the internet gateway makes the VPC internet-accessible but does not ensure high availability.

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.

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.

Internet Gateway Requirement:

For an Elastic IP (EIP) to be assigned to an instance's primary ENI, the VPC must have an Internet Gateway (IGW) attached. The IGW enables the VPC to communicate with the internet, allowing the EIP to function properly (Option C).

Process of Assigning EIP:

Once the Internet Gateway is attached to the VPC, the EIP can be successfully assigned to the primary ENI of the FortiGate VM, providing it with internet access.

Other Options Analysis:

Option A is incorrect because the primary ENI is already in a public subnet.

Option B is not necessary and may not solve the issue without an attached Internet Gateway.

Option D is partially correct about the routing table but does not address the primary issue of needing an Internet Gateway.

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.

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 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.
