CISM Information Security Program Practice Question
This CISM practice question tests your understanding of information security program. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
Exhibit
Refer to the exhibit.
Suspicious Activity Log:
Timestamp: 2025-03-21 14:32:15 UTC
Event ID: 5678
Source IP: 192.168.1.50
User: jdoe
Action: File download
File: payroll_encrypted.xlsx
Status: Failed - Encryption key not found
Additional Info: Downloaded using HTTPS from external IP 203.0.113.45
An information security manager reviews the suspicious activity log shown in the exhibit. The payroll file is supposed to be encrypted and only accessible internally. What is the MOST likely cause for the failed download?
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.

A
The user's encryption certificate has expired
Why wrong: Certificate expiration typically results in a certificate error, not an encryption key not found error.
B
The file was not encrypted before being uploaded
Why wrong: If the file were not encrypted, the download would succeed; the log indicates encryption is present but key missing.
C
The user lacked permission to decrypt the file
The 'Encryption key not found' error implies the user does not have the decryption key, likely due to insufficient permissions.
D
The external IP is blocked by the firewall
Why wrong: A firewall block would prevent the connection entirely, not result in a key-related failure.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The user lacked permission to decrypt the file
Option D is correct because the status 'Encryption key not found' indicates that the user does not have the necessary decryption key, likely due to lack of permission. Option A is wrong because certificate expiry would show a different error. Option B is wrong because if the file were not encrypted, it would download successfully. Option C is wrong because if the external IP were blocked, the download would not initiate.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
Use explanations to understand the rule behind the answer.
TExam Day Tips
→Underline the problem statement mentally.
→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 CISM 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.
