• Question 182:

  Your company has made plans to roll out OpenShift, a Kubernetes platform solution offered by IBM Red Hat, across all its on-premises and public cloud environments. Given that you are the lead architect responsible for your company's GCP deployments, what type of shared responsibility model will this deployment entail for you?

  A. SaaS

  B. On premises

  C. PaaS

  D. IaaS

  Correct Answer: D

  The key to remember here is that for a service provided (GCP in this case) to take responsibility for its PaaS, it must offer the service as a managed service. GCP offers its own Kubernetes platform called GKE. But OpenShift is not a Google-offered PaaS solution. As such, Google will not take responsibility for the back-end operations and design of your OpenShift environments. You will need to manage all the VMs that OpenShift will provision as part of its GCP deployment. So this is an IaaS deployment from a shared responsibility model perspective.

• Question 183:

  You are storing sensitive information in a Cloud Storage bucket. For legal reasons, you need to be able to record all requests that read any of the stored data. You want to make sure you comply with these requirements. What should you do?

  A. Scan the bucket using the Data Loss Prevention API.

  B. Enable Data Access audit logs for the Cloud Storage API.

  C. Enable the Identity Aware Proxy API on the project.

  D. Allow only a single Service Account access to read the data.

  Correct Answer: B

  Logged information Your Google Cloud projects contain only the audit logs for resources that are directly within the Cloud project. Other Google Cloud resources, such as folders, organizations, and billing accounts, contain the audit logs for the entity itself. Reference link-https://cloud.google.com/storage/docs/audit-logging

• Question 184:

  One of your customers used to have a private data center. While within their data center itself, they were consuming some Google services via API calls and other public, well-known addresses pub-lished by Google. Now they're evacuating their private data center and are moving to Google Cloud. Could they improve some of their existing architecture with respect to security?

  A. Use VPC Peering with the Google Cloud organization so that you can directly use services using only private IPs.

  B. Use private addresses only. No additional configuration is required. All Google services will be accessible within Google Cloud on private addresses.

  C. Use Shared VPCs with the Google Cloud organization so that you can directly use services using only private IPs.

  D. Enable Private Google Access so that they can remove public IP addresses.

  Correct Answer: D

  "VM instances that only have internal IP addresses (no external IP addresses) can use Private Google Access. They can reach the external IP addresses of Google APIs and services. f you disable Private Google Access, the VM instances can no longer reach Google APIs and services; they can only send traffic within the VPC network." https://cloud.google.com/vpc/docs/private-google-access

• Question 185:

• Question 186:

  A startup client of yours does offline data processing for a few of its clients. They are mi-grating their applications and the associated data to Google Cloud. They have 100TB of data to move. They presently have a very small private data center setup connected to a local internet provider. The maximum bandwidth they are able to get is 100Mbps. How long will it take them to transfer the data over the internet if the transfer goes smoothly?

  A. About 12 days.

  B. About 2 years.

  C. About 100 days.

  D. About 24 hours.

  Correct Answer: C

  The key reason I included this question is to clarify some terminologies that will be important for your estimates. The data size mentioned is a TB terabyte. Note the "byte". The speed is mentioned in Mbps, which is Megabits per second. Note the "bits". 8 bits make a byte. So, to get the actual number of bits transferred, you need to multiply the TB number by 8. Total data transferred (in bits) = 100 * 1,000,000,000,000 * 8 bits Speed = 100Mbps = 100 * 1,000,000. i.e. 100 million bits are transferred per second. Hence time taken to transfer all the data = Total Data/Speed = 8,000,000 seconds. Number of seconds in a day = 24*60*60 = 86,400 Total time taken in days = 8,000,000/86,400 = 92.59 days

• Question 188:

  Google offers Firebase, In terms of Firebase Console, any particular message that has to be deliv-ered to a customer at a certain degree of change in behavior can be managed through _________________.

  A. A/B testing

  B. Notification Composer

  C. Firebase Remote config.

  D. None of the above

  Correct Answer: B

  You can send notification messages using the Notifications composer in the Firebase console. Though this does not provide the same flexibility or scalability as sending messages with the Admin SDK or the HTTP and XMPP protocols, it can be very useful for testing or for highly targeted marketing and user engagement. The Firebase console provides analytics-based A/B testing to help refine and improve marketing messages. After you have developed logic in your app to receive messages, you can allow non-technical users to send messages per the instructions on the Notifications page in the Firebase Help Center.

  B. Triangular Scaling takes an automated average of Cost, Effort, and Time.

  C. Vertical Scaling

  D. Horizontal Scaling
