MLS-C01 Exploratory Data Analysis Practice Question
This MLS-C01 practice question tests your understanding of exploratory data analysis. 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.
Network Topology
A data scientist is exploring log files stored in S3. They ran the above AWS CLI command. What does the output indicate about the data, and what EDA step should be taken next?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
There are 3 log files larger than 100KB in the specified prefix.
Option B is correct because the command filters objects larger than 100000 bytes, and the output shows three large files. Option A is wrong because the command does not count all objects; it filters by size. Option C is wrong because the output shows three files, not all files. Option D is wrong because the command explicitly filters by size, so the output is not all objects.
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.
✗
All log files are about 150KB-200KB in size.
Why it's wrong here
Only files >100KB are shown; smaller files are omitted.
✗
There are 3 objects in the bucket under the prefix.
Why it's wrong here
The command only shows objects larger than 100000 bytes; there may be more smaller objects.
✓
There are 3 log files larger than 100KB in the specified prefix.
Why this is correct
The command filters by size >100000 bytes and returns keys and sizes.
Related concept
Read the scenario before looking for a memorised answer.
✗
The prefix 'logs/2023/' contains exactly 3 objects.
Why it's wrong here
The command filters, so it does not show all objects.
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.
Trap categories for this question
Command / output trap
Only files >100KB are shown; smaller files are omitted.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
