D.
Create a custom Compute Engine image from a snapshot. Create your instances from that image.
Answers
Suggested answer: D

Explanation:

A custom image belongs only to your project. To create an instance with a custom image, you must first have a custom image.

Preparing your instance for an image

You can create an image from a disk even while it is attached to a running VM instance. However, your image will be more reliable if you put the instance in a state that is easier for the image to capture. Use one of the following processes to prepare your boot disk for the image:

Stop the instance so that it can shut down and stop writing any data to the persistent disk.

If you can't stop your instance before you create the image, minimize the amount of writes to the disk and sync your file system.

Pause apps or operating system processes that write data to that persistent disk.

Run an app flush to disk if necessary. For example, MySQL has a FLUSH statement. Other apps might have similar processes.

Stop your apps from writing to your persistent disk.

Run sudo sync.

After you prepare the instance, create the image.

D.
Install and configure the Cloud Logging Agent and view the logs from Cloud Logging.
Answers
Suggested answer: D

Explanation:

Cloud Loging knows nothing about applications installed on the system without an agent collecting logs. Using the serial console is not a best-practice and is impractical on a large scale.

The VM images for Compute Engine and Amazon Elastic Compute Cloud (EC2) don't include the Logging agent, so you must complete these steps to install it on those instances. The agent runs under both Linux and Windows. Source: https://cloud.google.com/logging/docs/agent/logging/installation

Suggested answer: B

Explanation:

Predefined roles

The following table describes Identity and Access Management (IAM) roles that are associated with Cloud Storage and lists the permissions that are contained in each role. Unless otherwise noted, these roles can be applied either to entire projects or specific buckets.

Storage Object Creator (roles/storage.objectCreator) Allows users to create objects. Does not give permission to view, delete, or overwrite objects.

D.
Store credentials for your user account with appropriate access for Google services in a config file, and deploy this config file with your application.
Answers
Suggested answer: B

Explanation:

In general, Google recommends that each instance that needs to call a Google API should run as a service account with the minimum permissions necessary for that instance to do its job. In practice, this means you should configure service accounts for your instances with the following process: Create a new service account rather than using the Compute Engine default service account. Grant IAM roles to that service account for only the resources that it needs. Configure the instance to run as that service account. Grant the instance the https://www.googleapis.com/auth/cloud-platform scope to allow full access to all Google Cloud APIs, so that the IAM permissions of the instance are completely determined by the IAM roles of the service account. Avoid granting more access than necessary and regularly check your service account permissions to make sure they are up-to-date. https://cloud.google.com/compute/docs/access/create-enable-service-accounts-for-instances#best_practices

Quickstart: Creating a New Instance Using the Command Line

Before you begin

1. In the Cloud Console, on the project selector page, select or create a Cloud project.

2. Make sure that billing is enabled for your Google Cloud project. Learn how to confirm billing is enabled for your project.

To use the gcloud command-line tool for this quickstart, you must first install and initialize the Cloud SDK:

1. Download and install the Cloud SDK using the instructions given on Installing Google Cloud SDK.

2. Initialize the SDK using the instructions given on Initializing Cloud SDK.

To use gcloud in Cloud Shell for this quickstart, first activate Cloud Shell using the instructions given on Starting Cloud Shell.

D.
Create an Instance Template with Preemptible VMs On. Create a Managed Instance Group from the template and adjust Target CPU Utilization. Migrate the workload.
Answers
Suggested answer: D

Explanation:

Install the workload in a compute engine VM, start and stop the instance as needed, because as per the question the VM runs for 30 hours, process can be performed offline and should not be interrupted, if interrupted we need to restart the batch process again. Preemptible VMs are cheaper, but they will not be available beyond 24hrs, and if the process gets interrupted the preemptible VM will restart.

D.
Create a Metadata entry on the Compute Engine page with key compute/zone and value europe--west1--d.
Answers
Suggested answer: A

Explanation:

Change your default zone and region in the metadata server Note: This only applies to the default configuration. You can change the default zone and region in your metadata server by making a request to the metadata server. For example: gcloud compute project-info add-metadata \ --metadata google-compute-default-region=europe-west1,google-compute-default-zone=europe-west1-b The gcloud command-line tool only picks up on new default zone and region changes after you rerun the gcloud init command. After updating your default metadata, run gcloud init to reinitialize your default configuration. https://cloud.google.com/compute/docs/gcloud-compute#change_your_default_zone_and_region_in_the_metadata_server

The core business of your company is to rent out construction equipment at a large scale. All the equipment that is being rented out has been equipped with multiple sensors that send event information every few seconds. These signals can vary from engine status, distance traveled, fuel level, and more. Customers are billed based on the consumption monitored by these sensors. You expect high throughput -- up to thousands of events per hour per device -- and need to retrieve consistent data based on the time of the event. Storing and retrieving individual signals should be atomic. What should you do?

D.
Ingest the data into Cloud Bigtable. Create a row key based on the event timestamp.
Answers
Suggested answer: D

Explanation:

Keyword need to look for

- 'High Throughput',

- 'Consistent',

- 'Property based data insert/fetch like ngine status, distance traveled, fuel level, and more.' which can be designed in column,

- 'Large Scale Customer Base + Each Customer has multiple sensor which send event in seconds' This will go for pera bytes situation,

- Export data based on the time of the event.

- Atomic

o BigTable will fit all requirement.

o DataStore is not fully Atomic

o CloudStorage is not a option where we can export data based on time of event. We need another solution to do that

o FireStore can be used with MobileSDK.
