You want to make a copy of a production Linux virtual machine in the US-Central region. You want to
manage and replace the copy easily if there are changes on the production virtual machine. You will deploy the copy as a new instances in a different project in the US-East region. What steps must you take?

A.

Use the Linux dd and netcat command to copy and stream the root disk contents to a new virtual
machine instance in the US-East region.

B.

Create a snapshot of the root disk and select the snapshot as the root disk when you create a new virtual
machine instance in the US-East region.

C.

Create an image file from the root disk with Linux dd command, create a new disk from the image file,
and use it to create a new virtual machine instance in the US-East region

D.

Create a snapshot of the root disk, create an image file in Google Cloud Storage from the snapshot, and
create a new virtual machine instance in the US-East region using the image file for the root disk

The application reliability team at your company has added a debug feature to their backend service to send all
server events to Google Cloud Storage for eventual analysis. The event records are at least 50 KB and at most
15 MB and are expected to peak at 3,000 events per second. You want to minimize data loss.
Which process should you implement?

A.

Append metadata to file body.
• Compress individual files.
• Name files with serverName-Timestamp.
• Create a new bucket if bucket is older than 1 hour and save individual files to the new bucket.
Otherwise, save files to existing bucket

B.

Batch every 10,000 events with a single manifest file for metadata.
• Compress event files and manifest file into a single archive file
Name files using serverName-EventSequence.
• Create a new bucket if bucket is older than 1 day and save the single archive file to the new bucket.
Otherwise, save the single archive file to existing bucket.

C.

Compress individual files.
• Name files with serverName-EventSequence.
• Save files to one bucket
• Set custom metadata headers for each object after saving.

D.

Append metadata to file body.
• Compress individual files.
• Name files with a random prefix pattern.
• Save files to one bucket

Your solution is producing performance bugs in production that you did not see in staging and test
environments. You want to adjust your test and deployment procedures to avoid this problem in the future. What should you do?

A.

Deploy fewer changes to production.

B.

Deploy smaller changes to production.

C.

Increase the load on your test and staging environments.

D.

Deploy changes to a small subset of users before rolling out to production.

A news teed web service has the following code running on Google App Engine. During peak load, users

The session variable is being overwritten in Cloud Datastore.

C.

The URL of the API needs to be modified to prevent caching.

D.
