• Question 161:

  You are using Deployment Manager to create a Google Kubernetes Engine cluster. Using the same Deployment Manager deployment, you also want to create a DaemonSet in the kube-system namespace of the cluster. You want a solution that uses the fewest possible services. What should you do?

  A. Add the cluster's API as a new Type Provider in Deployment Manager, and use the new type to create the DaemonSet.

  B. Use the Deployment Manager Runtime Configurator to create a new Config resource that contains the DaemonSet definition.

  C. With Deployment Manager, create a Compute Engine instance with a startup script that uses kubectl to create the DaemonSet.

  D. In the cluster's definition in Deployment Manager, add a metadata that has kube-system as key and the DaemonSet manifest as value.

  Correct Answer: A

  Adding an API as a type provider

  This page describes how to add an API to Google Cloud Deployment Manager as a type provider. To learn more about types and type providers, read the Types overview documentation.

  A type provider exposes all of the resources of a third-party API to Deployment Manager as base types that you can use in your configurations. These types must be directly served by a RESTful API that supports Create, Read, Update, and

  Delete (CRUD).

  If you want to use an API that is not automatically provided by Google with Deployment Manager, you must add the API as a type provider.

• Question 162:

  Your company has an existing GCP organization with hundreds of projects and a billing account. Your company recently acquired another company that also has hundreds of projects and its own billing account. You would like to consolidate all GCP costs of both GCP organizations onto a single invoice. You would like to consolidate all costs as of tomorrow. What should you do?

  A. Link the acquired company's projects to your company's billing account.

  B. Configure the acquired company's billing account and your company's billing account to export the billing data into the same BigQuery dataset.

  C. Migrate the acquired company's projects into your company's GCP organization. Link the migrated projects to your company's billing account.

  D. Create a new GCP organization and a new billing account. Migrate the acquired company's projects and your company's projects into the new GCP organization and link the projects to the new billing account.

  Correct Answer: A

  The keywords are "as of tomorrow" and "single invoice". The quickest(the only?) way of achieving this is by Linking. The proper way would be under C, but that's not possible in 24h or less.

• Question 163:

  You need to deploy an application, which is packaged in a container image, in a new project. The application exposes an HTTP endpoint and receives very few requests per day. You want to minimize costs. What should you do?

  A. Deploy the container on Cloud Run.

  B. Deploy the container on Cloud Run on GKE.

  C. Deploy the container on App Engine Flexible.

  D. Deploy the container on Google Kubernetes Engine, with cluster autoscaling and horizontal pod autoscaling enabled.

  Correct Answer: A

  Cloud Run takes any container images and pairs great with the container ecosystem: Cloud Build, Artifact Registry, Docker. ... No infrastructure to manage: once deployed, Cloud Run manages your services so you can sleep well. Fast autoscaling. Cloud Run automatically scales up or down from zero to N depending on traffic.

  D. 1. Deploy your application on Cloud Run on GKE with the connectivity set to Internal.

  2.

  Create a Cloud Pub/Sub subscription for that topic.

  3.

  In the same Google Kubernetes Engine cluster as your application, deploy a container that takes the messages and sends them to your application.

  Correct Answer: C

  C. is the correct answer: Create a service account. 2. Give the Cloud Run Invoker role to that service account for your Cloud Run application. 3. Create a Cloud Pub/Sub subscription that uses that service account and uses your Cloud Run application as the push endpoint

• Question 165:

  You are hosting an application on bare-metal servers in your own data center. The application needs access to Cloud Storage. However, security policies prevent the servers hosting the application from having public IP addresses or access to the internet. You want to follow Google-recommended practices to provide the application with access to Cloud Storage. What should you do?

  A. 1. Use nslookup to get the IP address for storage.googleapis.com.

  2.

  Negotiate with the security team to be able to give a public IP address to the servers.

  3.

  Only allow egress traffic from those servers to the IP addresses for storage.googleapis.com.

  B. 1. Using Cloud VPN, create a VPN tunnel to a Virtual Private Cloud (VPC) in Google Cloud Platform (GCP).

  2.

  In this VPC, create a Compute Engine instance and install the Squid proxy server on this instance.

  3.

  Configure your servers to use that instance as a proxy to access Cloud Storage.

  C. 1. Use Migrate for Compute Engine (formerly known as Velostrata) to migrate those servers to Compute Engine.

  2.

  Create an internal load balancer (ILB) that uses storage.googleapis.com as backend.

  3.

  Configure your new instances to use this ILB as proxy.

  D. 1. Using Cloud VPN or Interconnect, create a tunnel to a VPC in GCP.

  2.

  Use Cloud Router to create a custom route advertisement for 199.36.153.4/30. Announce that network to your on-premises network through the VPN tunnel.

  3.

  In your on-premises network, configure your DNS server to resolve *.googleapis.com as a CNAME to restricted.googleapis.com.

  Correct Answer: D

  VPN/interconnect without exposing to public

• Question 166:

  Your organization is a financial company that needs to store audit log files for 3 years. Your organization has hundreds of Google Cloud projects. You need to implement a cost-effective approach for log file retention. What should you do?

  A. Create an export to the sink that saves logs from Cloud Audit to BigQuery.

  B. Create an export to the sink that saves logs from Cloud Audit to a Coldline Storage bucket.

  C. Write a custom script that uses logging API to copy the logs from Stackdriver logs to BigQuery.

  D. Export these logs to Cloud Pub/Sub and write a Cloud Dataflow pipeline to store logs to Cloud SQL.

  Correct Answer: B

  Hundreds of projects means many logs. Bigquery is the good Storage.

• Question 167:

  You want to run a single caching HTTP reverse proxy on GCP for a latency-sensitive website. This specific reverse proxy consumes almost no CPU. You want to have a 30-GB in-memory cache, and need an additional 2 GB of memory for the rest of the processes. You want to minimize cost. How should you run this reverse proxy?

  A. Create a Cloud Memorystore for Redis instance with 32-GB capacity.

  B. Run it on Compute Engine, and choose a custom instance type with 6 vCPUs and 32 GB of memory.

  C. Package it in a container image, and run it on Kubernetes Engine, using n1-standard-32 instances as nodes.

  D. Run it on Compute Engine, choose the instance type n1-standard-1, and add an SSD persistent disk of 32 GB.

  Correct Answer: A

  Go to cloud console and create instance select Memorystore with Basic tier, select us-central1 and us-central1-a, and capacity 32GB, the cost estimate is $0.023/GB/hr

  select VM instance with custom machine type with 6 vCPUs and 32 GB memory, the same region and zone as Memorystore setting, the cost estimate is $0.239/hr

  Option B will definitely cost more as it adds on CPU usage cost even it uses little in this scenario, but still charge you. So answer is A from real practice example.

• Question 168:

  You have a web application deployed as a managed instance group. You have a new version of the application to gradually deploy. Your web application is currently receiving live web traffic. You want to ensure that the available capacity does not decrease during the deployment. What should you do?

  A. Perform a rolling-action start-update with maxSurge set to 0 and maxUnavailable set to 1.

  B. Perform a rolling-action start-update with maxSurge set to 1 and maxUnavailable set to 0.

  C. Create a new managed instance group with an updated instance template. Add the group to the backend service for the load balancer. When all instances in the new managed instance group are healthy, delete the old managed instance group.

  D. Create a new instance template with the new application version. Update the existing managed instance group with the new instance template. Delete the instances in the managed instance group to allow the managed instance group to recreate the instance using the new instance template.

  Correct Answer: B

  We need to ensure the global capacity remains intact, for that reason we need to establish maxUnavailable to 0. On the other hand, we need to ensure new instances can be created. We do that by establishing the maxSurge to 1. Option C is more expensive and more difficult to set up and option D won't meet requirements since it won't keep global capacity intact.
