CS0-003 Incident Response and Management Practice Question
This CS0-003 practice question tests your understanding of incident response and management. 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.
Refer to the exhibit. An analyst reviews file access logs and notices the entries above. Which is the MOST likely conclusion?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The user jsmith's credentials may have been compromised.
The exhibit shows file access logs with multiple failed attempts followed by a successful access from an unusual IP address (10.10.10.10) for user jsmith, which is outside the normal corporate subnet. This pattern of brute-force or password-spraying attempts culminating in a successful login from an anomalous location strongly indicates credential compromise, not authorized activity.
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.
✗
The file server is misconfigured.
Why it's wrong here
No evidence of misconfiguration; access was authenticated.
✗
It is a false positive due to time zone differences.
Why it's wrong here
Time zone cannot explain the different source IP and device.
✗
The user jsmith is performing authorized research.
Why it's wrong here
Accessing payroll at 3 AM from remote is not typical research.
✓
The user jsmith's credentials may have been compromised.
Why this is correct
Unusual time and device indicate possible credential misuse.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the distinction between a simple misconfiguration (which would show consistent failures or permission errors) and a security incident (which shows a pattern of failed attempts followed by success from an anomalous source).
Detailed technical explanation
How to think about this question
In Windows file server auditing, Event ID 4625 (failed logon) and Event ID 4624 (successful logon) are logged with source network addresses. A sudden spike of 4625 events from an external IP followed by a 4624 from the same IP is a classic indicator of a password-spraying or brute-force attack. Real-world attackers often use tools like Hydra or Medusa to test common passwords against a single account, and once successful, they pivot to lateral movement or data exfiltration.
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 security analyst at a medium-sized enterprise encounters this scenario during an investigation or architecture review. The correct answer reflects best practice for the specific threat or control described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Security exam questions test whether you can match controls to threats in context — not just recall definitions.
