NSE6_WCS-7.0 Practice Exam Questions and Answers

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 VP

C.  

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

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.

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.

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.

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.
