,Q1. A network administrator notices that traffic from a specific subnet is not being
inspected by the SonicWall IPS engine even though the IPS policy is set to 'Enable'
globally. The subnet is behind a layer-3 switch and uses a virtual interface on the
SonicWall. What is the most likely reason for this lack of inspection?
A. The IPS engine does not inspect traffic on virtual interfaces.
B. The access rule for that subnet has the 'Enable IPS' option unchecked.
C. The layer-3 switch is bypassing the SonicWall because of asymmetric routing.
D. The SonicWall's default policy for that zone has 'IPS' disabled.
Correct Answer: B. The access rule for that subnet has the 'Enable IPS' option
unchecked.
Rationale: In SonicWall, IPS inspection is applied on a per-access-rule basis. Even if the
global IPS setting is enabled, each access rule must have the 'Enable IPS' checkbox
selected for traffic matching that rule to be inspected. Virtual interfaces support IPS, so
option A is incorrect. Asymmetric routing can cause issues but is less likely if the subnet is
behind a virtual interface; option C is a possible cause but not as direct. Option D is
incorrect because global settings override zone defaults for inspection.
Why Wrong:
A - Virtual interfaces fully support IPS inspection; the issue is not the interface type.
C - Asymmetric routing could cause inspection bypass, but it is not the most direct
cause when access rules are misconfigured.
D - Zone defaults are overridden by access rule settings; the global enable would
apply unless overridden.

Q2. During a site-to-site VPN configuration, you must ensure that traffic between two
remote networks is encrypted using AES-256 and hashed with SHA-256. The VPN
policy is configured accordingly, but you notice that the Phase 2 proposal on the peer
device uses AES-128. What will happen when the VPN tunnel is established?
A. The tunnel will fail to establish because Phase 2 proposals must match exactly.
B. The tunnel will establish using the strongest common proposal (AES-256).
C. The tunnel will establish using AES-128 because the peer's proposal takes
precedence.
D. The tunnel will establish but with a warning about the weak algorithm.
Correct Answer: A. The tunnel will fail to establish because Phase 2 proposals must
match exactly.
Rationale: In IPsec VPN, Phase 2 (IPsec SA) proposals must match on both ends for the
tunnel to establish. If one side proposes AES-256 and the other only supports AES-128, the
negotiation fails because no common proposal is found. There is no automatic fallback to
the strongest or weakest common algorithm; the tunnel simply does not come up. Thus,
options B and C are incorrect. Option D is incorrect because the tunnel would not
Page 3
, establish at all.
Why Wrong:
B - VPN negotiation does not select a 'strongest common' proposal; it requires an
exact match.
C - There is no unilateral precedence; both sides must agree on the same proposal.
D - A mismatch prevents establishment entirely, not just a warning.

Q3. A SonicWall appliance is configured with multiple WAN interfaces in a
load-balancing group. You want to ensure that traffic from a specific internal server
always uses the same WAN IP for outbound connections to a particular external
service. Which SonicWall feature should be used to achieve this?
A. Policy-based routing
B. Source-based routing
C. Outbound load balancing with sticky connections
D. NAT policy with a specified WAN interface
Correct Answer: D. NAT policy with a specified WAN interface
Rationale: To ensure that traffic from a specific internal server to a specific external
service always uses the same WAN IP, you can create a NAT policy that specifically maps
that server's traffic to a chosen WAN interface. This overrides the default load-balancing
behavior. Policy-based routing (A) can route based on source, but it doesn't guarantee the
same WAN IP for NAT; it affects routing decisions, not the source IP translation.
Source-based routing (B) is similar to PBR but still doesn't ensure a specific NAT IP.
Outbound load balancing with sticky connections (C) maintains the same WAN for the life
of a connection, but not necessarily for all connections from that server; it does not
guarantee a specific WAN for a specific service.
Why Wrong:
A - Policy-based routing can influence the route but does not control which WAN IP
is used for NAT.
B - Source-based routing is a type of policy routing and does not ensure a specific
WAN IP for NAT.
C - Sticky connections only maintain the same WAN for a single connection, not for
all connections to a specific service.

Q4. You are troubleshooting a slow throughput issue on a SonicWall with multiple
security services enabled. The CPU usage is consistently high, and you suspect that
the security services are causing a bottleneck. Which of the following actions is most
likely to improve throughput without significantly reducing security?
A. Disable all security services on the internal zone.
