Cisco Conducting Forensic Analysis and Incident Response Using Cisco Technologies for Cybersecurity Exam Practice Test
The 300-215 CBRFIR exam concerns forensic analysis and incident response using Cisco technologies for cybersecurity. Its subject area includes collecting and interpreting digital evidence, examining endpoint and network activity, and making defensible response decisions. The practice bank samples scenarios involving Windows and Linux artifacts, packet captures, suspicious files, timestamp correlation, evidence handling, and remediation after a suspected intrusion.
Exam overview
About the Cisco Conducting Forensic Analysis and Incident Response Using Cis… Exam
Forensic work requires preserving volatile information before it disappears, documenting collection steps, and maintaining a traceable chain of custody. Analysts may correlate firewall and endpoint records, account for clock differences, and distinguish what encrypted traffic reveals from what it cannot establish. Packet analysis can help identify application protocols even when traffic uses an unusual port, while host artifacts can support investigation of remote logons and running processes. Suspicious executables should be examined in a controlled environment rather than opened on a production system. Responders also need to assess the limits of cloud-provider records, communicate findings so another reviewer can reproduce the analysis, and choose remediation that reduces immediate exposure without destroying evidence needed for investigation.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
A response team has identified a vulnerable internet-facing service that the attacker may have exploited. What is a sound remediation step after preserving necessary evidence and addressing immediate risk?
Show answer
Correct answer: ARemediation should address the underlying weakness, such as by applying a supported patch or correcting an insecure configuration, followed by verification. A name change or assumption about filtering does not remove the vulnerability.
A responder suspects that a Windows host may have been compromised through a remote interactive session. Which artifact can help show whether Remote Desktop logons occurred?
Show answer
Correct answer: AWindows Security logs can record successful and failed logon activity, including logon types associated with remote interactive access. Interpret these events with account, host, and time context; a log entry alone does not prove malicious access.
A security analyst is correlating events from a firewall and an endpoint, but their timestamps differ by several minutes. What is the most appropriate first step before drawing conclusions about event order?
Show answer
Correct answer: BClock skew and differing time zones can make related events appear out of order. Establishing offsets and normalizing timestamps supports a more defensible timeline while preserving uncertainty about the original times.
An analyst receives a suspicious executable for examination. Which approach most safely obtains an initial behavioral view?
Show answer
Correct answer: AA properly isolated analysis environment limits potential impact while allowing observation of file, process, and network behavior. The environment should be controlled and reset or restored after testing.
An analyst finds a suspicious file in a collected evidence set. Which practice best preserves a clear chain of custody?
Show answer
Correct answer: AA chain-of-custody record documents evidence control and handling. This helps others assess whether the item remained accounted for and supports the credibility of later analysis.
A forensic team is asked to provide findings that may be reviewed by people outside the technical team. Which reporting practice best supports reproducibility and clear evaluation?
Show answer
Correct answer: AA clear report records how evidence was examined, the tools and versions used, limitations, and how observations support conclusions. This helps technical reviewers assess and, when appropriate, reproduce the work.
When reviewing a packet capture, an analyst needs to determine whether a particular file transfer occurred over an encrypted connection. What is the most accurate conclusion from observing TLS traffic alone?
Show answer
Correct answer: ATLS generally protects application contents in transit, so a packet capture may reveal connection metadata while not exposing transferred file contents. Other authorized sources, such as endpoint telemetry or proxy logs, may provide additional evidence.
How to use this practice test
The free practice session draws up to 20 random questions from the 50-question bank. Use it to check how you apply forensic handling, artifact interpretation, network analysis, and incident-response reasoning to short scenarios. Results appear after the session; revisit any missed decisions and identify which evidence or assumptions would change the conclusion.
Preparation tips
- Practice documenting evidence acquisition, file handling, and custody transfers so that another analyst can trace each item from collection through examination.
- Compare Windows event records and Linux live-response data, paying attention to which artifacts can answer questions about remote access, processes, and active connections.
- Work through packet-capture scenarios that distinguish protocol identification from conclusions about payload contents, especially when traffic is encrypted or uses a nonstandard port.
- Before correlating logs, check clock settings and time zones; record any offset before inferring the sequence of firewall and endpoint events.
- For cloud and malware scenarios, identify collection limits, preserve relevant records, use isolated analysis environments, and separate evidence preservation from containment or remediation.
