NSE5_FWB_AD-8.0 Fortinet NSE 5 - FortiWeb 8.0 Administrator Free Practice Exam Questions (2026 Updated)

When FortiWeb is deployed behind a load balancer or upstream proxy, it may see only the load balancer IP address as the source for every request. This causes poor client identification and can lead FortiWeb to block many legitimate users as if they are one abusive client. The correct fix is to preserve the original client IP address in an HTTP header, commonly using X-Forwarded-For or a similar trusted client-IP header. FortiWeb can then be configured to read that header for accurate client identification, logging, rate limiting, and IP-based security decisions. Bot detection, signature updates, and HTTPS caching do not solve the core source-IP visibility problem.

This is a stored cross-site scripting attack. The attacker submits JavaScript into a product review form, and the application stores and displays it later to other users. When victims view the review, their browsers execute the attacker’s script as if it came from the trusted site. That is dangerous because the script can access browser-side data available to the page, such as cookies, tokens, page content, or session-related information depending on browser and cookie security settings. It does not directly leak the back-end database; that would be more aligned with SQL injection. It also does not inherently bypass login pages or require the victim to click a link. The core risk is malicious code execution in the victim’s browser.

The exhibit is written in structured OpenAPI/YAML-style format. It includes fields such as info, version, title, servers, paths, HTTP method get, operationId, responses, content type application/json, and a schema definition. That is not HTML and it is not a live API response. It is also not CLI output from FortiWeb. FortiWeb OpenAPI validation uses OpenAPI description files in YAML or JSON to define API structure, endpoints, parameters, and expected data types. FortiWeb then uses that uploaded schema as a baseline to validate API requests and block requests that do not conform. So the exhibit is best identified as an API schema file

The issue is unauthorized access through a mobile API, so the control must enforce API-specific identity and access rules. FortiWeb API protection can validate API structure, methods, paths, and authorization requirements, while client management can help associate requests with legitimate clients or authenticated users. ZTNA profiles and cookie security can help with access and session protection, but they do not replace API-specific authorization controls. Switching reverse-proxy mode to bypass cookie controls makes no sense and could weaken protection. Replacing ZTNA with bot protection addresses a different problem: automation, not API authorization. Logging only records activity after the fact and does not prevent bypass. The correct action is to enable API protection and client management for mobile API traffic.

================

Traffic logging is more storage-intensive than normal event or attack logging, so FortiWeb does not always expose policy traffic-log selection by default. The Study Guide states that traffic logs must be enabled from the CLI before they can be selected in a server policy. This matches the exhibit: the administrator is in the server policy wizard but cannot see the traffic log option. FortiAnalyzer or FortiSIEM can receive logs, but they do not make the policy option appear. Deployment mode is also not the determining factor here. FortiAppSec Cloud licensing is unrelated. The correct cause is that global traffic logging must first be enabled manually through the CLI, after which policy-based traffic logging can be selected.

================

The requirement is to track user behavior over time and respond when cumulative activity becomes risky. FortiWeb client management and threat scoring are built for that purpose. When enabled in the protection profile, FortiWeb can associate activity with a client, assign threat weights to suspicious behavior, and apply actions such as alerting, denying, or period blocking after a defined score threshold is exceeded. Rate limiting is useful for traffic volume, but it does not evaluate a user’s full behavior pattern. A custom signature blocks a specific pattern immediately, not cumulative behavior. Cookie security protects session cookies but does not calculate behavioral risk. The correct configuration is scoring in the protection profile to track and respond to repeated risky actions.

================

The FortiGate is acting as an upstream reverse proxy, so FortiWeb sees the FortiGate address as the direct source IP unless it is configured to read the original client IP from the inserted HTTP header. Since FortiGate already inserts X-Forwarded-For, the proper fix is to modify the FortiWeb protection profile or related client-IP configuration so FortiWeb uses that header for client IP detection. This restores accurate logging, rate limiting, reputation checks, and IP-based enforcement. Changing to one-arm proxy is unnecessary and disruptive. Disabling IP-based detection weakens protection instead of fixing attribution. Recreating the policy with a predefined profile does not address the missing client IP mapping. The correct adjustment is to trust and use X-Forwarded-For.

The exhibits show a mismatch between the configured server pool and the server pool referenced by the server policy. The server pool containing the two back-end servers is named app-server-pool1 , but the server policy is selecting server-pool1 . In reverse proxy mode, FortiWeb receives traffic on the virtual server and then forwards it to the server pool selected in the server policy. If the policy points to the wrong or empty pool, traffic will not be forwarded to the intended back-end servers, even if health checks for the correct pool are healthy. Client Real IP affects source IP preservation, not pool selection. The FortiGate should forward traffic to FortiWeb, not directly bypass it. The correct fix is to select the correct server pool.
