- A
The timestamp has been deliberately erased or not set, possibly to avoid forensic analysis.
Malware authors often zero out the timestamp to hinder timeline analysis.
- B
The file is digitally signed.
Why wrong: Digital signatures do not affect the header timestamp field.
- C
The file was compiled on January 1, 1970 (Unix epoch).
Why wrong: A zero timestamp technically corresponds to the epoch, but that is unlikely for a legitimate file.
- D
The file is a DLL rather than an executable.
Why wrong: DLLs also have timestamps; zero is not normal for either.

200-201 Host-Based Analysis Practice Question
This 200-201 practice question tests your understanding of host-based 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.
An analyst is examining a PE file and notices that the 'TimeDateStamp' in the optional header is 0x00000000. What does this suggest?
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
✓
The timestamp has been deliberately erased or not set, possibly to avoid forensic analysis.
A timestamp of zero often indicates the linker did not set it, which is common for malware or files compiled with certain tools that omit the timestamp.
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 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.
