Question 364 of 507
Network Intrusion AnalysishardMultiple ChoiceObjective-mapped

Quick Answer

The answer is URL filtering logs for traffic to 203.0.113.10, as they provide the specific HTTP/HTTPS request details needed to confirm a true positive. While a syslog message may flag a connection to a known malicious IP, URL filtering logs reveal the full URI, user agent, and category of the request, allowing you to verify whether the traffic was intentionally malicious or a benign misconfiguration. On the Cisco CyberOps Associate 200-201 exam, this tests your ability to correlate multiple log sources—specifically, using URL filtering logs to validate security events and reduce false positives. A common trap is relying solely on the syslog alert without cross-referencing the actual web request details, which can lead to misclassification. Remember the mnemonic “URLs Unmask Reality” to recall that URL filtering logs provide the granular context needed to confirm intent and maliciousness.

200-201 Network Intrusion Analysis Practice Question

This 200-201 practice question tests your understanding of network intrusion analysis. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.

Given the syslog message, which additional data would best confirm the event as a true positive?

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

URL filtering logs for traffic to 203.0.113.10

The syslog message likely indicates a security event such as a connection to a known malicious IP (203.0.113.10). URL filtering logs provide the specific HTTP/HTTPS request details (e.g., URI, user agent, category) that can confirm whether the traffic was intentional and malicious, rather than a false positive from a benign service or misconfiguration.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • VPN logs for user authentication

    Why it's wrong here

    VPN logs are unrelated to CnC detection.

  • URL filtering logs for traffic to 203.0.113.10

    Why this is correct

    URL filtering can reveal if the destination is a known malicious site.

    Clue confirmation

    The clue word "best" in the question point toward this answer.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Antivirus logs on 10.0.0.5

    Why it's wrong here

    Antivirus logs may not capture network-based CnC activity.

  • NetFlow data showing other connections from 10.0.0.5

    Why it's wrong here

    NetFlow shows patterns but not malicious intent.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Cisco often tests the difference between network-layer metadata (NetFlow) and application-layer logs (URL filtering), trapping candidates who think flow data alone can confirm a malicious event.

Trap categories for this question

  • Command / output trap

    NetFlow shows patterns but not malicious intent.

Detailed technical explanation

How to think about this question

URL filtering logs typically include the full URI, HTTP method, referrer, and category (e.g., 'Malware' or 'Command and Control'), which allows correlation with threat intelligence feeds. In contrast, NetFlow records only contain IPs, ports, and protocol, missing the application-layer context that distinguishes a benign API call from a C2 beacon. This distinction is critical because many modern threats use HTTPS on standard ports, making flow-level data insufficient for confirmation.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.

TExam Day Tips

  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

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.
