Practice Test 1 | AWS Certified Solutions Architect Associate | SAA-C03 | Dumps | Mock Test
You are developing an application using AWS SDK to get objects from AWS S3. The objects have big sizes. Sometimes there are failures when getting objects, especially when the network connectivity is poor. You want to get a specific range of bytes in a single GET request and retrieve the whole object in parts. Which method can achieve this?
A. Enable multipart upload in the AWS SDK.
B. Use the “Range” HTTP header in a GET request to download the specified range bytes of an object.
C. Reduce the retry requests and enlarge the retry timeouts through AWS SDK when fetching S3 objects.
D. Retrieve the whole S3 object through a single GET operation.
Explanation:
Correct Answer – B
Through the “Range” header in the HTTP GET request, a specified portion of the objects can be downloaded instead of the whole objects. Check the explanations in https://docs.aws.amazon.com/AmazonS3/latest/dev/GettingObjectsUsingAPIs.html.
- Option A is incorrect: Because the question asks for multipart download rather than multipart upload.
- Option B is CORRECT: Because with byte-range fetches, users can establish concurrent connections to Amazon S3 to fetch different parts from within the same object.
- Option C is incorrect: Because adjusting retry requests and timeouts cannot download specific parts of an object.
- Option D is incorrect: Because the method to retrieve the entire object does not meet the requirement.
