CCNA Practice Question: A network administrator at a large enterprise…
This 200-301 practice question tests your understanding of 200-301 exam topics. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A network administrator at a large enterprise notices that the network monitoring system frequently generates false positive alerts for unusual traffic patterns during normal business hours. The administrator wants to reduce these false positives while still detecting genuine security threats. Which AI/ML concept would best address this requirement?

Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Implement an anomaly detection system that uses machine learning to establish baseline behavior and flag deviations.
Anomaly detection using machine learning can learn the normal traffic patterns over time and then identify deviations that are genuinely suspicious, reducing false positives. Predictive analytics forecasts future events, intent-based networking automates policy enforcement, and deep packet inspection inspects packet contents but does not inherently reduce false positives.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Deploy a predictive analytics model to forecast future traffic volumes and adjust thresholds accordingly.
Why it's wrong here
Predictive analytics focuses on forecasting future trends rather than identifying anomalies, so it would not directly reduce false positives from current traffic patterns.
- ✓
Implement an anomaly detection system that uses machine learning to establish baseline behavior and flag deviations.
Why this is correct
Anomaly detection with ML learns normal traffic baselines and adapts to changes, which significantly reduces false positives by only alerting on genuine anomalies.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
- ✗
Apply intent-based networking to automatically enforce security policies based on high-level business intent.
Why it's wrong here
Intent-based networking automates policy deployment and verification, but it does not inherently reduce false positive alerts from monitoring systems.
- ✗
Use deep packet inspection to examine all traffic and create static rules for known threats.
Why it's wrong here
Deep packet inspection can detect known threats but does not adapt to new patterns, so it would not reduce false positives from normal traffic variations.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 200-301 exam frequently reuses these exact scenarios with slightly different constraints.

Why this is wrong here
Predictive analytics predicts future behavior but does not adaptively distinguish between normal and anomalous traffic in real time.
✗Apply intent-based networking to automatically enforce security policies based on high-level business intent.Wrong answer — click to see why▾
Why this is wrong here
Intent-based networking focuses on policy automation, not on improving the accuracy of anomaly detection.
✗Use deep packet inspection to examine all traffic and create static rules for known threats.Wrong answer — click to see why▾
Why this is wrong here
Deep packet inspection relies on static signatures, which can still generate false positives and cannot learn normal behavior.

Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related 200-301 NAT questions on configuration and troubleshooting.
