NSE4_FGT_AD-7.6 Dumps with Practice Exam Questions Answers

According to the FortiOS 7.6 Study Guide and technical documentation, conserve mode is a protective state triggered when memory utilization reaches the Extreme Threshold (typically 95% by default). When this occurs, the FortiGate implements several measures to prioritize system stability over new functionality. One of the primary restrictions is that the FortiGate refuses to accept configuration changes (Statement B). This prevents the system from initiating new processes or allocating additional memory that could lead to a total system crash.

Regarding traffic handling, the behavior is determined by specific "fail-open" settings. For the IPS engine, if the fail-open global setting is enabled, the FortiGate continues to transmit packets without IPS inspection (Statement D). This ensures that network connectivity is maintained even when the system lacks the memory resources to perform deep packet inspection. In contrast, Statement A is incorrect because the system may skip non-essential actions to save memory. Statement C is incorrect because conserve mode is designed to avoid a system halt; the device remains operational and will automatically exit conserve mode once memory usage drops below the Release Threshold (typically 82%).

Based on the FortiOS 7.6 Authentication and User Group documentation, the correct answer is A.

Meaning of “Include in every user group” (FortiOS 7.6)

When configuring a RADIUS server on FortiGate, enabling Include in every user group has a very specific and documented effect:

The configured RADIUS server object is automatically added to all FortiGate user groups.

As a result, any user who successfully authenticates against that RADIUS server becomes a valid member of every FortiGate user group, unless additional group filtering (such as RADIUS attributes) is applied.

This simplifies configuration when the same external authentication source must be accepted across multiple firewall policies that reference different user groups.

This behavior is explicitly described in the FortiOS 7.6 Administrator Guide under RADIUS authentication servers and user groups.

Why Option A is Correct

FortiGate user groups can include:

Local users

LDAP servers

RADIUS servers

Enabling Include in every user group causes FortiGate to:

Insert the RADIUS server into all existing and future FortiGate user groups

Therefore, all users authenticating via this RADIUS server are implicitly allowed in every FortiGate user group.

This is exactly what option A describes.

Why the Other Options Are Incorrect

B: FortiGate does not push users or groups into the RADIUS server. Authentication is always initiated by FortiGate toward RADIUS.

C: FortiGate does not manage or modify RADIUS-side group definitions.

D: LDAP and RADIUS user groups are separate authentication mechanisms; this setting does not merge or affect LDAP groups.

In FortiOS 7.6, when FortiGate is integrated with FortiAnalyzer and FortiManager, firewall policies rely on a Universally Unique Identifier (UUID) to ensure proper policy tracking, synchronization, and log correlation across devices.

Why the UUID is required

Every firewall policy in FortiOS has a UUID.

FortiManager uses the UUID to:

Track policies across managed FortiGate devices

Maintain policy consistency during installs and revisions

FortiAnalyzer uses the UUID to:

Correlate logs accurately to the correct firewall policy

Preserve log association even if policy order or policy ID changes

Without a UUID:

Policy-to-log mapping can break

FortiManager cannot reliably manage or synchronize policies

FortiAnalyzer log analysis becomes inconsistent

This is explicitly documented in Fortinet administration and logging architecture references.

Why the other options are incorrect

B. Policy IDPolicy ID can change when policies are moved and is not reliable for long-term correlation across FortiManager and FortiAnalyzer.

C. Sequence IDSequence ID reflects GUI ordering only and has no role in log correlation.

D. Log IDLog ID is generated per log event, not per firewall policy.

According to the FortiOS 7.6 Study Guide and technical documentation regarding High Availability (HA), the FortiGate Clustering Protocol (FGCP) uses a specific set of rules to elect the primary unit in a cluster. By default, the election order follows: Connected Monitored Ports > HA Uptime > Priority > Serial Number.

However, when the HA override setting is enabled, the election logic is modified to prioritize the administrator-defined priority value over the uptime of the cluster members. In this specific configuration, the election process follows this sequence:

Connected monitored ports: The unit with the most functioning monitored interfaces is preferred.

Priority: The unit with the highest manually configured priority value (e.g., 255) is selected next.

HA uptime: If monitored ports and priority are equal, the unit that has been up in the HA cluster the longest is chosen.

FortiGate serial number: As a final tie-breaker, the unit with the higher serial number is elected.1

Statement A is correct because it reflects the shift where Priority is evaluated immediately after monitored ports, overriding the standard uptime advantage. Statements B and D are incorrect because the FGCP uses HA uptime, not system uptime, for its calculations.

From the current HA status, HQ-NGFW-1 is the primary and HQ-NGFW-2 is the secondary.

The administrator then changes these HA parameters:

HQ-NGFW-1: set override disable, set priority 90

HQ-NGFW-2: set override enable, set priority 110

In FGCP (A-P mode), the override (preemption) feature controls whether a higher-priority unit is allowed to take over the primary role.

When override is enabled, the cluster will prefer (and can re-elect) the unit with the highest device priority to become primary (preempting a lower-priority primary when conditions trigger re-election behavior as defined by FGCP).

Here, HQ-NGFW-2 has:

override enabled

higher priority (110) than HQ-NGFW-1 (90)

Therefore, the expected result is that HQ-NGFW-2 becomes the primary.

Why the other options are incorrect:

B is incorrect because it claims HQ-NGFW-2 has lower priority (it is higher: 110 > 90).

C is incorrect because a mismatch in the override setting is not what causes the “configuration out of sync” condition shown in get system ha status (that is about synchronized configuration databases, not a requirement that override values must match to remain in-sync).

D is incorrect because HA settings like override/priority are not synchronized in the way regular configuration objects are; they are device-level HA parameters.
