This MLS-C01 practice question tests your understanding of exploratory data analysis. 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.
A data engineer is performing EDA on a time-series dataset of server metrics (CPU, memory, disk I/O) collected every minute. The dataset contains 2 years of data. The engineer suspects there are seasonal patterns and wants to decompose the time series for one metric. Which AWS service can be used to perform this decomposition natively?
Amazon SageMaker Canvas
Canvas provides time-series analysis and decomposition.
Amazon Athena with SQL window functions
Why wrong: Athena cannot perform decomposition.
Amazon QuickSight
Why wrong: QuickSight is for visualization, not decomposition.
AWS Glue DataBrew
Why wrong: DataBrew is for data preparation, not time-series decomposition.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Amazon SageMaker Canvas
Option A is correct because Amazon SageMaker Canvas supports time-series forecasting with built-in decomposition. Option B is wrong because AWS Glue does not have time-series decomposition. Option C is wrong because Amazon QuickSight does not decompose time series. Option D is wrong because Amazon Athena does not have decomposition functions.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Amazon SageMaker Canvas
Why this is correct
Canvas provides time-series analysis and decomposition.
Related concept
Static NAT maps one inside address to one outside address.
Amazon Athena with SQL window functions
Why it's wrong here
Athena cannot perform decomposition.
Amazon QuickSight
Why it's wrong here
QuickSight is for visualization, not decomposition.
AWS Glue DataBrew
Why it's wrong here
DataBrew is for data preparation, not time-series decomposition.
Common exam traps
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related MLS-C01 NAT questions on configuration and troubleshooting.
