The correct choice is AWS Elemental MediaConvert for video transcoding because it is a fully managed, serverless service that automatically scales to handle sporadic bursts of uploads without idle costs, and it can complete each video within the required 30-minute window. MediaConvert is purpose-built for transcoding, offering advanced features like ABR streaming and DRM, whereas EC2 Auto Scaling incurs costs even when idle and requires manual scaling management, and Elastic Transcoder is deprecated with fewer capabilities. On the AWS Certified Solutions Architect Professional SAP-C02 exam, this scenario tests your ability to match a serverless, cost-optimized service to a variable workload—a common trap is choosing Lambda, which has a hard 15-minute timeout and lacks the codec support for full transcoding jobs. Remember the memory tip: for media processing, think “MediaConvert for heavy lifting, Lambda for quick triggers.”
SAP-C02 Design for New Solutions Practice Question
This SAP-C02 practice question tests your understanding of design for new solutions. 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 media company is designing a video transcoding pipeline. They receive raw video files in Amazon S3, which need to be transcoded into multiple formats. The pipeline must handle sporadic bursts of uploads and complete processing within 30 minutes for each video. The cost should be minimized. Which design should they use?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Amazon S3 event notifications to trigger an AWS Elemental MediaConvert job.
Option A is correct because AWS Elemental MediaConvert is a serverless transcoding service that scales automatically and is cost-effective for sporadic workloads. Option B is wrong because EC2 Auto Scaling requires management and incurs costs even when idle. Option C is wrong because Elastic Transcoder is being deprecated and has less features. Option D is wrong because Lambda has a 15-minute timeout and is not suitable for transcoding.
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.
✗
Use AWS Lambda with layers containing FFmpeg to transcode videos.
Why it's wrong here
Lambda has a 15-minute execution limit and 10 GB memory limit, insufficient for transcoding large videos.
✓
Use Amazon S3 event notifications to trigger an AWS Elemental MediaConvert job.
Why this is correct
MediaConvert is serverless, scales automatically, and is cost-effective for sporadic jobs.
Related concept
Read the scenario before looking for a memorised answer.
✗
Provision a cluster of EC2 instances running FFmpeg, with Auto Scaling based on SQS queue depth.
Why it's wrong here
EC2 instances incur costs even when idle; management overhead is higher.
✗
Use Amazon Elastic Transcoder, which is fully managed and triggers from S3 events.
Why it's wrong here
Elastic Transcoder is legacy and being replaced by MediaConvert; also less feature-rich.

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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.

Variation 1. A media company runs a video processing pipeline on AWS. Videos are uploaded to an S3 bucket, which triggers an AWS Lambda function that transcodes the video into multiple formats using FFmpeg. The transcoding job runs on the Lambda function with a 15-minute timeout. Recently, the company started receiving 4K videos that take more than 15 minutes to transcode. The Lambda function times out, and the video is not processed. The company wants to process these large videos without increasing the Lambda timeout and without rewriting the entire pipeline. What should the solutions architect do?
medium
✓ A.Replace the Lambda function with AWS Elemental MediaConvert job triggered by S3 events.
B.Increase the Lambda function memory to the maximum to improve performance and reduce processing time.
C.Use AWS Step Functions to call multiple Lambda functions in parallel to process chunks of the video.
D.Use a Lambda function with a larger ephemeral storage to handle the video file.
Why A: Option A is correct. AWS Elemental MediaConvert is a managed service designed for video transcoding. It can handle large files and long-running jobs. The pipeline can be modified to trigger a MediaConvert job instead of a Lambda function. Option B is incorrect because Lambda functions have a maximum execution time of 15 minutes; increasing memory does not extend timeout. Option C is incorrect because using a larger Lambda function still has the 15-minute limit. Option D is incorrect because Step Functions orchestrate Lambda functions but do not extend the individual Lambda timeout.
