Question #1 (Topic: Demo Questions)

An organization has decided to modernize their applications in the cloud to keep up with their customers ' needs.

What may have prompted this business decision?

Their on-premises applications only autoscale to meet demand.

They want to change from a pay-as-you-go model to a capital expenditure model.

Their source code changes erroneously without developer interaction.

Their on-premises applications take months to update and deploy.

Correct Answer: D

Question #2 (Topic: Demo Questions)

You are working for a hospital that stores its medical images in an on-premises data room and it is provided that the hospitals want to use Cloud Storage for archival storage of these images. You are required to design and implement a solution where the hospital wants an automated process to up-load any new medical images to Cloud Storage. On the basis of this statements which of the follow-ing statement is correct.

Create a Pub/Sub topic, and enable a Cloud Storage trigger for the Pub/Sub topic. Create an application that sends all medical images to the Pub/Sub topic.

Create a script that uses the gsutil command line interface to synchronize the on-premises storage with Cloud Storage. Schedule the script as a cron job.

In the Cloud Console, go to Cloud Storage. Upload the relevant images to the ap-propriate bucket.

Deploy a Dataflow job from the batch template, “Datastore to Cloud Storage” Schedule the batch job on the desired interval.

Correct Answer: B

Explanation:

Using sync for new images implies that you will continue to use your onprem and keep synchronizing it forever, Sync just once for the old images, new images go directly to google cloud via pub/sub, and eventually get rid of the onprem.

Question #3 (Topic: Demo Questions)

A financial services company is running an experimental application workload that has a very large number of mathematical calculations involving floating-point numbers. The current application that is running on compute engine is not providing enough speed and throughput. What are the options to increase the processing performance?

Use a serverless option like Cloud Functions that will automatically scale as much as required.

Instead of using a " general purpose " machine family, use " compute-optimized " machine family.

Since processing could also be dependent on reading and writing data to the disk, use a fast Local SSD.

Attach GPUs to the virtual machine for number crunching.

Correct Answer: D

Explanation:

Compute Engine provides graphics processing units (GPUs) that you can add to your virtual machines (VMs). You can use these GPUs to accelerate specific workloads on your VMs such as machine learning and data processing.
