Quick Answer
The answer is the source and destination IP addresses. These two pieces of information are essential for intrusion alert correlation because they directly identify the communicating endpoints—the attacker’s origin and the targeted asset—allowing an analyst to scope the incident and initiate containment actions. On the Cisco CyberOps Associate 200-201 exam, this concept tests your understanding of network-based sensor data and how to link alerts to specific hosts in an enterprise environment. A common trap is focusing on the alert timestamp or protocol type, but the exam emphasizes that IP addresses are the foundational data points for correlating multiple alerts into a single attack narrative. Remember the mnemonic “IPs for ID” — the IP addresses give you the identity of the attacker and victim, which is the first step in any incident response workflow.
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 TWO pieces of information are essential for an analyst to correlate when investigating an intrusion alert from a network-based sensor?
The color of the network cables
Why wrong: Irrelevant to alert correlation.
Source and destination IP addresses
IP addresses identify the communicating hosts.
The brand of the sensor
Why wrong: Brand does not affect correlation.
Timestamp of the alert
Timestamp allows chronological correlation.
The name of the security team lead
Why wrong: Not relevant to alert data.

Correct answer & explanation
Source and destination IP addresses
Source and destination IP addresses are essential because they allow the analyst to identify the communicating endpoints involved in the intrusion attempt. By correlating these addresses with other alert data, the analyst can determine the origin of the attack and the targeted asset, which is critical for scoping the incident and initiating containment actions.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Cisco often tests the distinction between operational data (IP addresses, timestamps) and irrelevant administrative or physical details, trapping candidates who confuse 'essential for correlation' with 'nice to have' or 'commonly known' information.
Detailed technical explanation
When correlating network-based intrusion alerts, the timestamp is crucial for establishing a timeline of events, enabling the analyst to align the alert with other logs (e.g., firewall, proxy, or endpoint logs) to reconstruct the attack sequence. In practice, analysts often use the timestamp to query SIEM or packet capture (PCAP) data for the exact window of the incident, ensuring they do not miss related activity that occurred seconds before or after the alert. This correlation is fundamental to distinguishing a true positive from a false positive, as a single alert may be part of a larger, time-bound attack pattern.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
