Practice Test 2 | Google Cloud Certified Professional Cloud Architect | Dumps | Mock Test
You have a few media files over 5GB each that you need to migrate to Google Cloud Storage. The files are in your on-premises data center. What migration method can you use to help speed up the transfer process?
A. Use multi-threaded uploads using the -m option.
B. Use parallel uploads to break the file into smaller chunks then transfer it simultaneously.
C. Use the Cloud Transfer Service to transfer.
D. Start a recursive upload.
Correct Answer: B
Option A is incorrect– Use multi-threaded uploads using the -m option.
If you have a large number of files to transfer you might want to use the gsutil -m option, to perform a parallel (multi-threaded/multi-processing) copy:
gsutil -m cp -r dir gs://my-bucket
Option B (Correct answer) – Parallel uploads are for breaking up larger files into pieces for faster uploads.
gsutil can automatically use object composition to perform uploads in parallel for large, local files being uploaded to Google Cloud Storage. If enabled (see below), a large file will be split into component pieces that are uploaded in parallel and then composed in the cloud (and the temporary components finally deleted).
gsutil -o GSUtil:parallel_composite_upload_threshold=150M cp bigfile gs://your-bucket
Option C is incorrect. Use the Cloud Transfer Service to transfer. Storage Transfer Service is limited to AWS S3, Google Cloud Storage, On-premise and HTTP/HTTPS locations.
Our requirement is “help speed up the transfer process”
Using Option C, we can migrate but will not help to increase speed.
Option D is incorrect Start a recursive upload: The -R and -r options are synonymous. Causes directories, buckets, and bucket subdirectories to be copied recursively.
