NSE6_WCS-7.0 Fortinet NSE 6 - Cloud Security 7.0 for AWS Questions and Answers

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.

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.

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.

Understanding Fortinet HA CloudFormation Template:

The Fortinet High Availability (HA) CloudFormation template is used to automate the deployment and configuration of FortiGate instances in AWS.

Staging and Bootstrapping FortiGate:

Staging involves preparing the necessary configuration files and resources needed for deployment.

Bootstrapping is the process of automatically configuring FortiGate instances upon deployment.

S3 Bucket Requirement:

The configuration files required for staging and bootstrapping are typically stored in an S3 bucket.

Since the deployment is in the Ohio (US-East-2) region, it is recommended to host the S3 bucket in the same region to minimize latency and ensure regional compliance.

Comparison with Other Options:

Option A is incorrect because while an S3 bucket is required, it should be in the same region (US-East-2).

Option B is incorrect as the template does not automatically create the S3 bucket.

Option D is incorrect as DynamoDB is not used for staging and bootstrapping in this scenario.

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.

Cluster Elastic IP Address (EIP) Movement:

During a failover in an active-passive (A-P) cluster, the Elastic IP (EIP) associated with the active FortiGate instance (FGT-1) needs to be moved to the passive instance (FGT-2), which becomes the new active instance. This ensures that the traffic directed to the EIP is now handled by FGT-2 (Option A).

Secondary IP Address Movement:

The secondary IP address on Port2 of the current active instance (FGT-1) is moved to the same port on the new active instance (FGT-2). This step is crucial to ensure seamless network traffic redirection and connectivity for the services relying on that IP address (Option B).

Other Options Analysis:

Option C is incorrect because the static route modification mentioned is not directly related to the failover process described.

Option D is incorrect because no additional route needs to be added to the HA Sync AZ2 subnet route table to forward traffic to the Internet Gateway during a failover.

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.
