NSE5_SSE_AD-7.6 Exam Dumps : Fortinet NSE 5 - FortiSASE and SD-WAN 7.6 Core Administrator

According to theSD-WAN 7.6 Core Administratorstudy guide andFortiOS 7.6 Administration Guide, the "implicit rule" is the default rule at the bottom of the SD-WAN rule list (ID 0). It is only evaluated if traffic does not match any manually configured SD-WAN rules.

Policy Route Table Context (Option B): SD-WAN rules are technically a specialized form of policy-based routing. For a packet to match theimplicit rule, it must first pass through the routing hierarchy. If traffic matches the implicit rule, it indicates that it did not match any higher-priority user-defined SD-WAN rules or any specific entries in the manualpolicy route tablethat would have intercepted the traffic earlier.

Session Information (Option E): When you use the CLI to inspect an active session (e.g., diagnose sys session list), the output contains a field for theSD-WAN Service ID. If traffic is steered by a user-defined rule, it displays the ID of that rule (e.g., service_id=1). However, when traffic falls through to theimplicit rule, the session information displaysno SD-WAN service ID(it often shows as 0 or is omitted), because the implicit rule does not function as a "service" in the same way user-defined rules do.

Routing Behavior: The implicit rule follows the standard routing table (RIB/FIB) logic. It uses thepriorityanddistanceof the static routes to determine the path. If multiple paths have the same distance and priority, it uses the algorithm set by v4-ecmp-mode, but this is a function of the routing engine, not the SD-WAN engine itself.

Why other options are incorrect:

Option A: While v4-ecmp-mode (e.g., source-ip-based) is used for ECMP routing, this is part of the general FortiOS routing behavior for equal-cost paths in the FIB, whereas the implicit rule simply "hands over" the decision to that routing table.

Option C: When traffic matches the implicit rule, the session is actually flagged with vwl_id=0 and potentially dirty if a route change occurs, but vwl_default is not the standard flag name used in this specific context in the curriculum.

Option D: This is incorrect because the implicit ruledoes respect weight, distance, and priorityas defined in the static routes within the routing table; it does not distribute traffic "regardless" of these values.

According to theSD-WAN 7.6 Core Administratorstudy guide and theFortiOS 7.6 Administration Guide, when you are migrating a production FortiGate to use SD-WAN, the most critical step involves reconfiguring how traffic is permitted and routed.

Reference Removal Requirement: Before an interface (such as wan1 or wan2) can be added as anSD-WAN member, it must be "unreferenced" in most parts of the FortiGate configuration. Specifically, if an interface is currently being used in an activeFirewall Policy, the system will prevent you from adding it to the SD-WAN bundle.

Firewall Policy Migration (Option A): In a production environment, you mustreplace the references to the physical interfacesin your firewall policies with the newSD-WAN virtual interface(or an SD-WAN Zone). For example, if your previous policy allowed traffic from internal to wan1, you must update that policy so theOutgoing Interfaceis now SD-WAN. This allows the SD-WAN engine to take over the traffic and apply its steering rules.

Modern Tools: While this used to be a purely manual process, FortiOS 7.x includes anInterface Migration Wizard(found underNetwork > Interfaces). This tool automates the "search and replace" function, moving all existing policy and routing references from the physical port to the SD-WAN object to ensure minimal downtime.

Why other options are incorrect:

Option B: While you do need to update your routing (e.g., creating a static route for 0.0.0.0/0 pointing to the SD-WAN interface), the curriculum specifically emphasizes the replacement of references infirewall policiesas the primary administrative hurdle, as policies are often more numerous and complex than the single static route required for SD-WAN.

Option C: You donotneed to disable the interface. It must be up and configured, just removed from other configuration references so it can be "absorbed" into the SD-WAN bundle.

Option D: SD-WAN is abase featureof FortiOS and doesnot require a separate licenseor a reboot to enable.

According to theFortiSASE 7.6 Feature Administration Guideand the latest updates to theNSE 5 SASEcurriculum, FortiSASE has introduced native lifecycle management for FortiClient agents to reduce the operational burden on IT teams who previously relied solely on third-party MDM (Mobile Device Management) or GPO (Group Policy Objects) for every update.

TheEndpoint Upgradefeature, found underSystem > Endpoint Upgradein the FortiSASE portal, allows administrators to perform the following:

Centralized Version Control: Administrators can see which versions are currently deployed and which "Recommended" versions are available from FortiGuard.

Scheduled Rollouts: You can choose to upgrade all endpoints or specific endpoint groups at a designated time, ensuring that upgrades do not disrupt business operations.

Status Monitoring: The portal provides a real-time dashboard showing the progress of the upgrade (e.g.,Downloading,Installing,Reboot Pending, orSuccess).

Manual vs. Managed: While MDM is still highly recommended for theinitial onboarding(the first time FortiClient is installed and connected to the SASE cloud), all subsequent upgrades can be handled natively by the FortiSASE portal.

Why other options are incorrect:

Option B: Manual upgrades are inefficient for large-scale deployments (~400 users in this scenario) and are not the intended "feature-rich" solution provided by FortiSASE.

Option C: "Onboarding" refers to the initial setup. Re-onboarding every time a version changes would be redundant and counterproductive.

Option D: While the system canmanagethe upgrade, it is not "auto-upgraded on demand" by the client itself without administrative configuration in the portal. The administrator must still define the target version and schedule.
