,Section A - Network Design AND Implementation WITH
GNS3
Q1.
In a GNS3 hybrid network combining physical appliances and virtual instances, which
design choice ensures that AI-driven anomaly detection can inspect traffic without
becoming a single point of failure?
A. Deploy the detection sensor as a virtual B. Use a network tap that mirrors traffic to a
machine on the same hypervisor as the dedicated AI analysis cluster with failover
network controller
C. Place the sensor inline at the core switch D. Configure the sensor to receive only
with no bypass mechanism NetFlow summaries from edge routers
Correct: B - Use a network tap that mirrors traffic to a dedicated AI analysis cluster with
failover
Rationale:A dedicated tap with failover provides full visibility without inline disruption. Inline
sensors create a failure point unless bypass is implemented. Hypervisor co-location risks
resource contention. NetFlow summaries lose payload detail needed for deep AI analysis.
Q2.
When training a supervised ML classifier for network intrusion detection using a dataset
with extreme class imbalance (0.01% attack traffic), which metric best evaluates real-world
detection capability while accounting for both false positives and false negatives?
A. Accuracy B. F1-score
C. Recall D. Precision
Correct: B - F1-score
Rationale:F1-score is the harmonic mean of precision and recall, balancing both error types.
Accuracy is misleading due to imbalance. Recall alone ignores false positives. Precision
alone ignores false negatives. F1 provides a single metric that penalizes both.
Q3.
A threat actor uses PowerShell to download and execute a payload from a remote server.
Which MITRE ATT&CK technique and tactic pair best describes this behavior?
A. T1059.001 (Command and Scripting B. T1105 (Ingress Tool Transfer) under
Interpreter) under Execution Command and Control

, Section A - Network Design AND Implementation WITH GNS3
C. T1055 (Process Injection) under Defense D. T1041 (Exfiltration Over C2 Channel)
Evasion under Exfiltration
Correct: A - T1059.001 (Command and Scripting Interpreter) under Execution
Rationale:PowerShell is a scripting interpreter (T1059.001) used to execute code—Execution
tactic. Ingress tool transfer (T1105) is for transferring tools to the victim, not the initial
execution. Process injection and exfiltration are different behaviors.
Q4.
In a SOAR playbook, after triage, an analyst wants to automatically contain a
compromised host without human approval. Which playbook design principle is most
critical to prevent unintended network-wide disruption?
A. Implementing a kill switch that allows B. Using a single automated action to block
manual override all outbound traffic
C. Running the playbook on every alert D. Hardcoding the host's IP address in the
regardless of severity playbook
Correct: A - Implementing a kill switch that allows manual override
Rationale:A kill switch provides a manual override to halt automated actions, limiting blast
radius. Blocking all traffic could disrupt legitimate services. Running on all alerts increases
false positives. Hardcoding IPs makes the playbook inflexible and error-prone.
Q5.
Which statistical property of a network traffic dataset most directly violates the
independent and identically distributed (i.i.d.) assumption in many ML models, thereby
degrading anomaly detection performance?
A. Temporal autocorrelation of traffic B. High dimensionality of feature vectors
features
C. Presence of categorical features D. Normalization of feature values
Correct: A - Temporal autocorrelation of traffic features
Rationale:Network traffic exhibits temporal correlations (e.g., bursts, periodic patterns),
violating i.i.d. High dimensionality and categorical features are issues but not i.i.d. violations.
Normalization is a preprocessing step, not a data property.
Q6.
In a GNS3 network, you simulate a ransomware attack that encrypts files and then
attempts to exfiltrate data. Which combination of MITRE ATT&CK tactics and techniques
should your SOAR playbook prioritize for automated detection and response?
