Quick Answer
The correct answer is that Power Automate has a file size limit that the video exceeds. This is because Power Automate’s built-in actions, such as “Get file content,” have a default 100 MB cap on the file size they can process, and large video files frequently surpass this threshold, causing the flow to fail. On the Microsoft Power Platform Fundamentals PL-900 exam, this question tests your understanding of Power Automate’s technical constraints when handling large media files, a common real-world scenario that trips up candidates who assume cloud services automatically handle any file size. A typical trap is thinking video formats are unsupported or that Azure Blob Storage imposes the limit, but the bottleneck is actually the flow’s file size limit, not the storage destination. Remember the memory tip: “100 MB is the gate—video files are often too great.”
This PL-900 practice question tests your understanding of demonstrate the capabilities of power automate. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 company uses Power Automate to monitor a SharePoint document library for new files and then copy them to an Azure Blob Storage container. The flow runs successfully for PDF files but fails for large video files. What is the most likely cause?
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.
The SharePoint connector cannot read video files.
Why wrong: SharePoint connector reads any file type.
The flow uses a 'Parallel branch' that cannot handle large files.
Why wrong: Parallel branches don't affect file size.
Power Automate has a file size limit that the video exceeds.
Default file size limit is 100 MB.
Azure Blob Storage does not support video file formats.
Why wrong: Azure Blob Storage supports any file type.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Power Automate has a file size limit that the video exceeds.
Option B is correct because Power Automate has a file size limit (default 100 MB) for actions like 'Get file content'. Video files often exceed this limit. Option A is wrong because video files are supported. Option C is wrong because parallel branches would not affect file size. Option D is wrong because Azure Blob Storage supports large files.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
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
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.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
