NSE7_SDW Practice Test 4 — 10 Questions

Question 1

You are troubleshooting an issue where traffic is not using an SD-WAN rule despite meeting criteria. What is the most likely cause?

Accepted Answer

A higher-priority SD-WAN rule is matching the traffic first.. SD-WAN rules are evaluated top-down. If a higher-priority rule matches the traffic, the lower-priority rule will never be reached.

Answer

The SD-WAN rule is disabled.

Answer

The Performance SLA has timed out.

Answer

The interface is not in an SD-WAN zone.

Question 2

An enterprise network uses OSPF over SD-WAN IPsec tunnels. The administrator notices that OSPF adjacency is constantly dropping over a specific backup SD-WAN member link due to intermittent packet loss. Which THREE configuration adjustments can improve OSPF stability over unstable SD-WAN IPsec links? (Choose three)

Accepted Answer

Configure OSPF network type as point-to-point on the IPsec tunnel interfaces to eliminate unnecessary DR/BDR elections. To stabilize OSPF over unstable WAN links, adjusting OSPF hello and dead intervals, configuring OSPF dead-drop or fast-hello settings carefully, or utilizing passive interfaces/MD5 authentication correctly helps. Furthermore, ensuring that OSPF timers match and are relaxed prevents unnecessary adjacency drops.

Answer

Set the OSPF router ID to 0.0.0.0 on all branch spokes

Answer

Disable OSPF hello packets entirely and rely on static default routes

Question 3

An administrator troubleshoots a scenario where traffic matching an application-based SD-WAN rule is bypassing the preferred high-speed MPLS tunnel and taking the backup broadband tunnel instead. Which THREE factors should the administrator check to resolve this routing discrepancy? (Choose three)

Accepted Answer

Inspect the member priorities and weights configured within the specific SD-WAN rule. When an SD-WAN rule bypasses preferred paths, potential causes include SLA health check failure (the preferred link fails the SLA threshold), incorrect rule evaluation order (an earlier rule matches first), or interface priority/weight settings within the rule. Checking these three areas is standard practice.

Answer

Verify the FortiGate factory default administrator password is changed

Answer

Check the physical layer OSI Model cable category connected to the FortiGate port

Question 4

An enterprise deploys ADVPN 2.0 with BGP and security profiles applied to traffic traversing the VPN overlay. Which THREE statements are correct regarding how security profiles and ADVPN 2.0 interact in FortiOS? (Choose three)

Accepted Answer

SSL inspection (DPI) applied on spoke firewall policies inspects decrypted traffic traversing the ADVPN shortcut tunnel. In ADVPN 2.0, when spokes establish direct shortcut tunnels, data flows directly between spokes without passing through the hub. Therefore, firewall policies and security profiles enforcing inspection must exist on the spoke FortiGates, not just the hub. Additionally, shortcut tunnels permit direct inspection on the spoke interfaces.

Answer

ADVPN 2.0 automatically disables all firewall inspection profiles on shortcut interfaces to maximize throughput

Answer

The hub FortiGate inspects all data packets exchanged between spokes even after a direct shortcut tunnel is established

Question 5

An administrator is troubleshooting BGP route propagation over SD-WAN IPsec tunnels where a branch office is not receiving specific routes from the datacenter hub. Which TWO CLI commands on the FortiGate are most useful for diagnosing BGP peering and advertised route issues? (Choose two)

Accepted Answer

get router info bgp neighbors advertised-routes. To troubleshoot BGP routing issues on FortiOS, commands examining the BGP summary, advertised routes, and received routes are essential. These include 'get router info bgp summary' and 'get router info bgp neighbors <ip> advertised-routes'.

Answer

execute ipsec tunnel list

Answer

diagnose sys sdwan member

Answer

get system interface physical

Question 6

Which command is used to verify the current status of SD-WAN members and their SLA health from the CLI?

Accepted Answer

diagnose sys sdwan health-check. The command 'diagnose sys sdwan health-check' shows the status of configured health checks and member reachability.

Answer

show router info bgp

Answer

get system interface

Answer

get system sdwan member

Question 7

When using SD-WAN templates, how are SD-WAN rules ordered?

Accepted Answer

Top to bottom. SD-WAN rules are evaluated from top to bottom, similar to standard firewall policies.

Answer

Based on the creation date

Answer

By the interface speed

Answer

Randomly

Question 8

When configuring SD-WAN services in a template, what does the 'Performance SLA' setting determine?

Accepted Answer

The criteria for path selection based on link quality. The Performance SLA defines the criteria (latency, jitter, loss) that must be met for a path to be considered 'healthy' for traffic.

Answer

The physical port priority

Answer

The maximum bandwidth allowed

Answer

The number of tunnels created

Question 9

Which THREE factors can affect the 'Performance SLA' logic in an SD-WAN template?

Accepted Answer

Packet loss threshold. Performance SLA evaluates paths based on measured latency, jitter, and packet loss compared to defined thresholds.

Answer

The firmware version of the FortiGate

Answer

The number of active VPN tunnels

Question 10

Which TWO configuration changes require a push from FortiManager to the FortiGate?

Accepted Answer

Changes to an SD-WAN template. Any change made in the FortiManager policy or template objects requires a push to keep the device config synchronized.

Answer

Changes to the log settings on the FortiGate local GUI

Answer

Adding a new user to the FortiGate local database

Answer

Changing the FortiManager admin password
