,Q1. A network administrator notices that traffic from a specific subnet is being
blocked by the default Intrusion Prevention Service (IPS) policy, even though a
firewall rule allows the traffic. The IPS logs show 'High Risk' events for that subnet.
Which action BEST resolves the issue while maintaining security?
A. Disable the IPS on the firewall rule to allow all traffic
B. Create an IPS exclusion for the subnet's IP range
C. Change the IPS policy to 'Log Only' for that subnet
D. Assign a custom IPS policy with lower severity thresholds to the rule
Correct Answer: D. Assign a custom IPS policy with lower severity thresholds to the
rule
Rationale: Custom IPS policies allow granular control over which signatures and
severities are enforced for specific traffic. By assigning a custom policy with adjusted
thresholds, the administrator can permit legitimate traffic while still blocking high-risk
attacks, thus maintaining security.
Why Wrong:
A - Disabling IPS entirely removes all threat protection, exposing the network to
attacks.
B - An exclusion would bypass IPS for the entire subnet, leaving all traffic
unprotected.
C - Setting to 'Log Only' would not prevent the traffic from being blocked; it only
changes logging.
Reference: SonicWALL SNSA Study Guide, IPS Policy Configuration, Chapter 7
Q2. In a route-based VPN using IKEv2, the tunnel is established but traffic is not
passing. 'show crypto ikev2 sa' displays the SA with status 'Active', but the route to
the remote subnet is missing. Which configuration is MOST likely the cause?
A. The VPN policy is using 'Aggressive Mode' instead of 'Main Mode'
B. The remote gateway's preshared key does not match
C. The route to the remote network is not configured or is not being advertised
D. The firewall rule allowing VPN traffic is not in place
Correct Answer: C. The route to the remote network is not configured or is not being
advertised
Rationale: In route-based VPNs, the IKE SA can be active even if no traffic traverses the
tunnel because the route to the remote network must exist to forward packets into the
tunnel. Without a proper route (static, dynamic, or via BGP), traffic will not be sent to the
VPN tunnel interface.
Why Wrong:
A - IKEv2 does not use Aggressive Mode; it has its own exchange methods.
B - A mismatched preshared key would prevent the SA from reaching 'Active' state.
Page 3
, D - A firewall rule is required for traffic to be permitted, but the SA active indicates
the tunnel is up; the issue is routing.

Q3. A SonicWALL NSA series firewall is configured with two WAN interfaces in load
balancing mode. The administrator wants to ensure that HTTPS traffic from a
specific internal server always exits through the primary WAN. Which feature should
be configured?
A. Outbound load balancing with source-based routing
B. Policy-based routing (PBR) with a route for the server's IP
C. NAT policy with a specific interface binding
D. Access rule specifying the primary WAN as the next hop
Correct Answer: B. Policy-based routing (PBR) with a route for the server's IP
Rationale: Policy-based routing allows the administrator to override the default routing
table based on source, destination, or service. By creating a PBR rule for the internal
server's IP and service HTTPS, traffic can be forced out the primary WAN interface,
ensuring consistent egress.
Why Wrong:
A - Source-based routing in load balancing does not guarantee a specific interface for
a single host; it distributes traffic.
C - NAT policies do not determine the egress interface; they only translate addresses.
D - Access rules control permission, not routing.
Reference: SonicWALL SNSA Guide, Policy-Based Routing, Chapter 5
Q4. During a security audit, it is discovered that a firewall rule intended to block all
traffic from a specific external IP is not working. The administrator checks the access
rules and confirms the rule is enabled and placed at the top. What is the MOST likely
reason the rule is not effective?
A. The firewall is in 'Stealth Mode' and not responding to the traffic
B. The rule's source is set to 'Any' instead of the specific IP
C. There is a NAT policy that translates the source IP before the access rule check
D. The traffic is being allowed by a more specific rule lower in the list
Correct Answer: C. There is a NAT policy that translates the source IP before the
access rule check
Rationale: In SonicOS, access rules are evaluated before NAT policies. However, if a NAT
policy translates the source address to a different IP (e.g., via inbound NAT), the access
rule may see the translated source, not the original external IP. Thus, the rule might not
match the traffic as intended.
