CORRECT ANSWERS & COMPREHENSIVE
RATIONALES [103]
This premium study guide contains highly realistic multiple-choice
questions with verified answers and in-depth rationales tailored for the
Sophos Firewall v20.0 Architect and Engineer exams. It comprehensively
covers core architectural domains including Xstream DPI architecture,
advanced SD-WAN routing policies, high availability synchronization, and
synchronized security configurations. Ideal for network engineers and IT
security students, this resource ensures a deep technical mastery of
complex firewall deployments to guarantee a first-time exam pass.
Question 1
What is the primary benefit of the Sophos Xstream
architecture Architecture?
A) Fast path processing via the DPI engine for
trusted traffic
B) Complete virtualization of physical interfaces
C) Elimination of the need for an internal database
D) Cloud-only inspection of TLS 1.3 traffic
Answer: A
Rationale: The Xstream architecture introduces
the Xstream Fast Path to offload trusted traffic
from the Deep Packet Inspection (DPI) engine,
significantly maximizing overall throughput and
reducing latency.
Question 2
,When configuring Sophos Transparent
Authentication Suite (STAS), which port must be
open on the workstation's local firewall to allow the
collector to perform WMI verification?
A) UDP 6060
B) TCP 135
C) UDP 500
D) TCP 443
Answer: B
Rationale: STAS collectors utilize Windows
Management Instrumentation (WMI) via RPC port
TCP 135 to actively query workstations for
logged-in user details.
Question 3
An administrator needs to configure a Route-Based
IPsec VPN. Which virtual interface type must be
created on the Sophos Firewall?
A) XFRM (Virtual Tunnel Interface)
B) GRE Tunnel Interface
C) RED Virtual Interface
D) Bridge Interface
Answer: A
Rationale: Route-Based VPNs require an XFRM
interface (Virtual Tunnel Interface), allowing
,administrators to bind static or dynamic routing
rules directly to the VPN tunnel.
Question 4
Which mechanism does Sophos Firewall v20.0 use
to deliver zero-day protection and analyze
suspicious files in a secure cloud sandbox?
A) Sophos Labs Intelix
B) FastPath Decryption
C) Xstream DPI Engine
D) Heartbeat Endpoint Isolation
Answer: A
Rationale: Sophos Labs Intelix is a cloud-based
service that executes suspicious files in a safe
sandboxed environment to spot zero-day
malware behaviors.
Question 5
In what order are policies evaluated when a packet
arrives at the Sophos Firewall?
A) Firewall Rules, NAT Rules, Policy Routes
B) Policy Routes, Firewall Rules, NAT Rules
C) NAT Rules, Policy Routes, Firewall Rules
D) Policy Routes, NAT Rules, Firewall Rules
Answer: B
Rationale: The processing routing sequence
evaluates Policy-Based Routing (PBR) first,
, followed by firewall rules to determine access,
and then finishes with NAT translations.
Question 6
Which High Availability (HA) mode on the Sophos
Firewall requires separate licenses for both the
primary and auxiliary appliances?
A) Active-Passive
B) Active-Active
C) Cluster Mode
D) Passive-Standby
Answer: B
Rationale: Active-Active HA mode requires both
units to actively process traffic, meaning both
appliances must possess matching, active
security feature licenses.
Question 7
When using the Sophos Central Orchestrator for SD-
WAN, what topology can be automatically deployed
with a few clicks?
A) Dynamic Full Mesh or Hub-and-Spoke
B) Ring Topology
C) Linear Bus Topology
D) Hybrid Point-to-Point only
Answer: A
Rationale: Sophos Central SD-WAN Connection
