Quick Answer
The answer is Collection, Detection, and Analysis. These three steps form the core of the network intrusion analysis process according to Cisco best practices, beginning with the systematic gathering of raw data from sources such as NetFlow, syslogs, and packet captures (PCAP) to preserve evidence, followed by identifying suspicious patterns or signatures in that data, and concluding with a deep examination to confirm and contextualize the threat. On the Cisco CyberOps Associate 200-201 exam, this question tests your understanding of the incident response workflow and the logical sequence that separates raw data acquisition from threat identification and final verification. A common trap is confusing "Response" or "Containment" as a step within the analysis process itself, but those actions occur after the three-step analysis cycle is complete. To remember the order, think of the acronym C-D-A: you must Collect before you can Detect, and you must Detect before you can Analyze.
This 200-201 practice question tests your understanding of network intrusion analysis. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Which three steps are part of the network intrusion analysis process according to Cisco best practices?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Collection
Collecting data from network sources is the first step.
Detection
Detecting anomalies or alerts is a core step.
Prevention
Why wrong: Prevention is a proactive measure, not part of analysis.
Analysis
Analyzing collected data to identify threats.
Remediation
Why wrong: Remediation occurs after analysis, as a response.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Collection
Collection is correct because the network intrusion analysis process begins with gathering raw data from sources such as NetFlow, syslogs, and packet captures (PCAP). This step ensures that all relevant evidence is preserved for subsequent detection and analysis, aligning with Cisco's best practices for incident response.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Cisco often tests the distinction between the analysis process steps and adjacent security functions (prevention, remediation) to see if candidates confuse the reactive analysis workflow with proactive or corrective actions.
Detailed technical explanation
Cisco's network intrusion analysis framework follows a linear workflow: Collection (gathering logs and flows), Detection (identifying anomalies via signatures or baselines), and Analysis (correlating events to determine root cause). Under the hood, tools like Cisco Stealthwatch or Security Onion rely on Collection to feed detection engines, while Analysis uses techniques such as timeline reconstruction and packet-level inspection to validate findings.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the 200-201 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
