NSE7_EFW Hard Questions — 25 Difficult Questions

Question 1

You are managing FortiGates across multiple ADOMs. How can you share common firewall objects (e.g., mail servers, common IP ranges) across these ADOMs?

Accepted Answer

Create objects in the Global Database. Using the 'Global Database' or 'Global Policy' objects allows administrators to define objects once and share them across multiple ADOMs.

Answer

Manually copy objects to each ADOM

Answer

Use the API to script the creation in every ADOM

Answer

Enable 'Object Sharing' in system settings

Question 2

An administrator notices that logs are not appearing in FortiManager for a specific FortiGate. What is the first thing to check to ensure log forwarding is active?

Accepted Answer

Log forwarding configuration on the FortiGate. Checking the 'Log Settings' on the FortiGate to ensure the 'Remote Logging' feature is enabled and pointing to the correct FortiManager/FortiAnalyzer IP.

Answer

The FortiManager license

Answer

The device's physical connection

Answer

The firmware version of the FortiGate

Question 3

You need to ensure that session synchronization between HA nodes is as efficient as possible. Which parameter should be tuned in the HA configuration?

Accepted Answer

session-pickup-delay. The 'session-pickup' setting, specifically 'session-pickup-delay', helps manage the timing and load of session synchronization to prevent CPU spikes.

Answer

monitor-interface

Answer

override

Answer

heartbeat-interval

Question 4

You are troubleshooting a policy installation failure where the FortiManager reports a 'Configuration conflict'. Which action should you perform to identify the root cause of the mismatch?

Accepted Answer

Use the 'Diff' feature in the Policy & Objects tab to compare the database and device config. The 'Check Configuration' or 'Diff' tool in the Policy & Objects tab allows administrators to compare the database version against the running device configuration to pinpoint the exact setting causing the conflict.

Answer

Force an 'Import Policy' operation

Answer

Reboot the FortiManager

Answer

Disable the policy package entirely

Question 5

A FortiManager administrator needs to ensure that logs from all enterprise FortiGates are aggregated and purged based on storage thresholds. Where is this configured?

Accepted Answer

FortiAnalyzer/Log Settings under Device Manager. The log retention and storage settings are managed in the FortiManager's 'FortiView' or 'Device Settings' regarding log management, specifically under 'Log Settings' where disk quota and retention policies are defined.

Answer

System settings under 'Network' tab

Answer

Global Policy settings

Answer

ADOM management settings

Question 6

A FortiGate is performing OSPF routing. You want to redistribute connected routes into OSPF, but only for a specific subnet. How can this be achieved?

Accepted Answer

Use a route map in the OSPF redistribute configuration. A route map must be applied during redistribution to filter the prefixes being injected.

Answer

Configure a distribute-list in the OSPF process

Answer

Use an IP prefix list under the OSPF area command

Answer

Use an access list under the interface configuration

Question 7

What is the effect of changing the IPS 'buffer' size on a FortiGate device?

Accepted Answer

It determines the maximum size of data packets to hold for inspection. Adjusting the IPS buffer affects how much data is held in memory for inspection, which can prevent packet drops during heavy traffic but increases memory load.

Answer

It disables the hardware acceleration engine

Answer

It changes the signature timeout

Answer

It increases the number of concurrent IPS connections

Question 8

An administrator is migrating a standalone FortiGate into an existing FortiManager. What happens to the existing firewall policies on the FortiGate during the import process?

Accepted Answer

They are imported and converted into a Policy Package. When importing, the FortiManager imports the configuration and creates a Policy Package; the existing policies are added to the 'Policy & Objects' database.

Answer

They are moved to a 'Disabled' state

Answer

They are deleted to ensure a clean slate

Answer

They are merged into the Global Policy

Question 9

When configuring an IPsec tunnel using IKEv2, which THREE parameters are commonly negotiated during Phase 1?

Accepted Answer

Encryption algorithm (e.g., AES-256). IKEv2 negotiates encryption, integrity, and Diffie-Hellman groups during the initial exchange.

Answer

TCP port selection

Answer

Firewall policy ID

Question 10

In a VDOM-enabled environment, how are administrative accounts managed?

Accepted Answer

Admins can be scoped to specific VDOMs. Administrative accounts can be restricted to specific VDOMs (Global admin vs. VDOM admin) for granular access control.

Answer

Only the root VDOM admin can change settings

Answer

Admins must be global

Answer

All admins see all VDOMs

Question 11

Which THREE items are included in the configuration file of a FortiGate?

Accepted Answer

User certificates. The configuration file contains system settings, policy rules, and interface definitions.

Answer

FortiGuard cached updates

Answer

Real-time session tables

Question 12

Which THREE types of traffic are typically NOT offloaded by the NP6 processor?

Accepted Answer

Traffic requiring proxy-based inspection. Traffic that requires complex inspection, such as encrypted traffic that hasn't been decrypted or specific types of tunnels without hardware support, is handled by the CPU.

Answer

Simple ICMP packets

Answer

Standard UDP traffic

Question 13

An administrator is troubleshooting an issue where hardware acceleration is not working after upgrading firmware. Which command identifies if the NP configuration has changed?

Accepted Answer

diag hardware npu np6 port-list. 'diag hardware npu np6 port-list' or similar status commands help verify the current operational state and mapping of physical ports to NPU cores.

Answer

config system npu

Answer

diagnose firewall npu

Answer

get hardware status

Question 14

When using 'set session-ttl' globally, which sessions are affected?

Accepted Answer

Only new sessions. Global session TTL settings apply to all sessions that do not have a specific override or a policy-based setting.

Answer

All sessions

Answer

Only TCP sessions

Answer

Only existing sessions

Question 15

Which feature allows an administrator to offload SSL inspection to the hardware?

Accepted Answer

CP offloading. The FortiASIC CP (Content Processor) hardware chips are specifically designed to offload CPU-intensive tasks like SSL/TLS decryption.

Answer

Flow-based inspection

Answer

IPS engine offloading

Answer

NP6 offloading

Question 16

Which THREE aspects of the FortiGate system are affected by changing the global 'set vdom-mode' to 'multi-vdom'?

Accepted Answer

CLI command hierarchy. Changing the VDOM mode affects the CLI hierarchy, the available memory for VDOMs, and how system resources are partitioned.

Answer

The HA cluster size

Answer

The physical port order

Question 17

Which parameter, when modified in a policy, causes a session flush for all active connections hitting that policy?

Accepted Answer

Action (Accept to Deny). Changing critical security profile settings or specific policy parameters that affect the session tuple typically triggers a session flush to ensure consistent security enforcement.

Answer

Schedule

Answer

Comments field

Answer

Policy Name

Question 18

An administrator needs to provide access to FortiManager for a junior team member who should only be able to view logs and reports. Which feature is used to define this access?

Accepted Answer

Answer

Access Control Lists (ACLs)

Answer

ADOM Assignment

Answer

User Groups

Question 19

Which THREE steps are involved in the 'Policy Package Installation' workflow?

Accepted Answer

Select the target device. The workflow involves selecting the package, choosing the target device, and executing the installation (with a preview).

Answer

Perform a factory reset

Answer

Reboot the target device

Question 20

Which THREE items are included in a Policy Package when it is pushed from FortiManager?

Accepted Answer
