SAA-C03 Question #245: Real Exam Question with Answer & Explanation
The correct answer is A: Turn on S3 Transfer Acceleration on the destination S3 bucket. Use multipart uploads to directly. The goal is totransfer 500 GB dailyfrom multiple global locationsquicklyintoa single S3 bucketwhile keeping operational complexity low. Turn on S3 Transfer Acceleration on the destination S3 bucket. Use multipart uploads to directly upload site data to the destination S3 bucket.
Question
A company collects data for temperature, humidity, and atmospheric pressure in cities across multiple continents. The average volume of data that the company collects from each site daily is 500 GB. Each site has a high-speed internet connection. The company wants to aggregate the data from all these global sites as quickly as possible in a single Amazon S3 bucket. The solution must minimize operational complexity. Which solution meets these requirements?
Options
- ATurn on S3 Transfer Acceleration on the destination S3 bucket. Use multipart uploads to directly
- BUpload the data from each site to an S3 bucket in the closest Region. Use S3 Cross-Region
- CSchedule AWS Snowball Edge Storage Optimized device jobs daily to transfer data from each
- DUpload the data from each site to an Amazon EC2 instance in the closest Region. Store the data
Explanation
The goal is totransfer 500 GB dailyfrom multiple global locationsquicklyintoa single S3 bucketwhile keeping operational complexity low. Turn on S3 Transfer Acceleration on the destination S3 bucket. Use multipart uploads to directly upload site data to the destination S3 bucket. S3 Transfer Acceleration (S3-TA)allowsfasterglobal uploads by routing traffic through Amazon CloudFront's globally distributed edge locations. Multipart uploadsimprove efficiency bybreaking large filesinto smaller parts, transferring them in Low operational complexity: No need for additional resources or manual replication. Why is this best? It ensureshigh-speed transferswhileminimizing complexity. Upload the data from each site to an S3 bucket in the closest Region. Use S3 Cross-Region Replication to copy objects to the destination S3 bucket. Then remove the data from the origin S3 While S3 Cross-Region Replication (CRR) can copy objects, itadds latencydue tosequential replicationrather than a directfasttransfer. Why not? S3 Transfer Acceleration is fasterand avoidsextra steps. Use AWS Snowball Edge for daily transfers. AWS Snowballis forbulk offline transfers, notdaily high-speed internet transfers. Why not? Unnecessary physical devices add operational overhead. Upload to EC2, store in EBS, snapshot, and restore in the destination Region. This approach isoverly complexand notoptimized for direct S3 ingestion. Why not? Too many steps and higher costs.
