Question : Multipart upload API allows you to stop and resume uploads.

: Which code snippet below returns the URL of a load balanced web site created in
1. True
2. False

Correct Answer : Get Lastest Questions and Answer :


Explanation: Multipart upload allows you to upload a single object as a set of parts. Each part is a contiguous portion of the objects data. You can upload these object parts independently and in any order. If transmission of any part fails, you can retransmit that part without affecting other parts. After all parts of your object are uploaded, Amazon S3 assembles these parts and creates the object. In general, when your object size reaches 100 MB, you should consider using multipart uploads instead of uploading the object in a single operation.

Improved throughput You can upload parts in parallel to improve throughput.
Quick recovery from any network issues Smaller part size minimizes the impact of restarting a failed upload due to a network error.
Pause and resume object uploads You can upload object parts over time. Once you initiate a multipart upload there is no expiry; you must explicitly complete or abort the multipart upload.
Begin an upload before you know the final object size You can upload an object as you are creating it.

Explanation: Multi-part upload API allows you to upload parts of an object once broken apart. As a file/object is being created the multi-part upload api will allow you to upload the file to s3. Only after all parts of the object have been uploaded do you execute the CompleteMultipartUpload api call which completes a multipart upload by assembling previously uploaded parts.

Question : Parts of a multipart upload will not be completed until the "complete" request has been called which puts all the parts of the file together.
: Parts of a multipart upload will not be completed until the
1. True
2. False

Correct Answer : Get Lastest Questions and Answer :

You first initiate the multipart upload and then upload all parts using the Upload Parts operation (see Upload Part). After successfully uploading all relevant parts of an upload, you call this operation to complete the upload. Upon receiving this request, Amazon S3 concatenates all the parts in ascending order by part number to create a new object. In the Complete Multipart Upload request, you must provide the parts list. You must ensure the parts list is complete, this operation concatenates the parts you provide in the list. For each part in the list, you must provide the part number and the ETag header value, returned after that part was uploaded.
