Google Google Certifications ASSOCIATE-CLOUD-ENGINEER Questions & Answers

• Question 211:

  You are analyzing Google Cloud Platform service costs from three separate projects. You want to use this information to create service cost estimates by service type, daily and monthly, for the next six months using standard query syntax. What should you do?

  A. Export your bill to a Cloud Storage bucket, and then import into Cloud Bigtable for analysis.

  B. Export your bill to a Cloud Storage bucket, and then import into Google Sheets for analysis.

  C. Export your transactions to a local file, and perform analysis with a desktop tool.

  D. Export your bill to a BigQuery dataset, and then write time window-based SQL queries for analysis.

  Correct Answer: D

  Solving this by first eliminating the options that don't suit us. By breaking down the question into the key requirements

  1.

  Analyzing Google Cloud Platform service costs from three separate projects.

  2.

  Using standard query syntax. -> (Relational data and SQL)

  A. 'Cloud Storage bucket'........'Cloud Bigtable'. Not feasible, mainly because cloud BigTable is not good for Structured Data (or Relational Data on which we can run SQL queries as per the question's requirements). BigTable is better suited for Semi Structured data and NoSQL data.

  B. 'Cloud Storage bucket'.....'Google Sheets'. Not Feasible because there is no use of SQL in this option, which is one of the requirements. C. Local file, external tools... this is automatically eliminated because the operation we need is simple, and there has to be a GCP native solution for this. We shouldn't need to rely on going out of the cloud for such a simple thing.

  D. 'BigQuery'.....'SQL queries' -> This is the right answer.

• Question 212:

  You have a single binary application that you want to run on Google Cloud Platform. You decided to automatically scale the application based on underlying infrastructure CPU usage. Your organizational policies require you to use virtual

  machines directly. You need to ensure that the application scaling is operationally efficient and completed as quickly as possible. What should you do?

  A. Create a Google Kubernetes Engine cluster, and use horizontal pod autoscaling to scale the application.

  B. Create an instance template, and use the template in a managed instance group with autoscaling configured.

  C. Create an instance template, and use the template in a managed instance group that scales up and down based on the time of day.

  D. Use a set of third-party tools to build automation around scaling the application up and down, based on Stackdriver CPU usage monitoring.

  Correct Answer: B

  Managed instance groups offer autoscaling capabilities that let you automatically add or delete instances from a managed instance group based on increases or decreases in load (CPU Utilization in this case). Autoscaling helps your apps gracefully handle increases in traffic and reduce costs when the need for resources is lower. You define the autoscaling policy and the autoscaler performs automatic scaling based on the measured load (CPU Utilization in this case). Autoscaling works by adding more instances to your instance group when there is more load (upscaling), and deleting instances when the need for instances is lowered (downscaling).

• Question 213:

  You need a dynamic way of provisioning VMs on Compute Engine. The exact specifications will be in a dedicated configuration file. You want to follow Google's recommended practices. Which method should you use?

  A. Deployment Manager

  B. Cloud Composer

  C. Managed Instance Group

  D. Unmanaged Instance Group

  Correct Answer: A

• Question 214:

  You have a Dockerfile that you need to deploy on Kubernetes Engine. What should you do?

  A. Use kubectl app deploy .

  B. Use gcloud app deploy .

  C. Create a docker image from the Dockerfile and upload it to Container Registry. Create a Deployment YAML file to point to that image. Use kubectl to create the deployment with that file.

  D. Create a docker image from the Dockerfile and upload it to Cloud Storage. Create a Deployment YAML file to point to that image. Use kubectl to create the deployment with that file.

  Correct Answer: C

  Reference https://cloud.google.com/kubernetes-engine/docs/tutorials/hello-app

  C is correct.

  A can be eliminated because kubectl app * is not a valid command

  B can be eliminated because gcloud app deploy deploys on app engine, not on kubernetes (also it still requires a config file pointing to the image).

  D is not correct, since you cannot deploy a container image directly from GCS

• Question 215:

  You need to update a deployment in Deployment Manager without any resource downtime in the deployment. Which command should you use?

  A. gcloud deployment-manager deployments create --config

  B. gcloud deployment-manager deployments update --config

  C. gcloud deployment-manager resources create --config

  D. gcloud deployment-manager resources update --config

  Correct Answer: B

  Reference: https://cloud.google.com/sdk/gcloud/reference/deployment-manager/deployments/update Additional tip, update and create resource is not even a command under deployment management service.

• Question 216:

  You need to run an important query in BigQuery but expect it to return a lot of records. You want to find out how much it will cost to run the query. You are using on-demand pricing. What should you do?

  A. Arrange to switch to Flat-Rate pricing for this query, then move back to on-demand.

  B. Use the command line to run a dry run query to estimate the number of bytes read. Then convert that bytes estimate to dollars using the Pricing Calculator.

  C. Use the command line to run a dry run query to estimate the number of bytes returned. Then convert that bytes estimate to dollars using the Pricing Calculator.

  D. Run a select count (*) to get an idea of how many records your query will look through. Then convert that number of rows to dollars using the Pricing Calculator.

  Correct Answer: B

  Reference: https://cloud.google.com/bigquery/docs/estimate-costs

  Under on-demand pricing, BigQuery charges for queries by using one metric: the number of bytes processed (also referred to as bytes read). You are charged for the number of bytes processed whether the data is stored in BigQuery or in an external data source such as Cloud Storage, Drive, or Cloud Bigtable. On-demand pricing is based solely on usage.

• Question 217:

  Your development team needs a new Jenkins server for their project. You need to deploy the server using the fewest steps possible. What should you do?

  A. Download and deploy the Jenkins Java WAR to App Engine Standard.

  B. Create a new Compute Engine instance and install Jenkins through the command line interface.

  C. Create a Kubernetes cluster on Compute Engine and create a deployment with the Jenkins Docker image.

  D. Use GCP Marketplace to launch the Jenkins solution.

  Correct Answer: D

  Reference: https://cloud.google.com/solutions/using-jenkins-for-distributed-builds-on-compute-engine Market place makes things easier.

• Question 218:

  You are deploying an application to App Engine. You want the number of instances to scale based on request rate. You need at least 3 unoccupied instances at all times. Which scaling type should you use?

  A. Manual Scaling with 3 instances.

  B. Basic Scaling with min_instances set to 3.

  C. Basic Scaling with max_instances set to 3.

  D. Automatic Scaling with min_idle_instances set to 3.

  Correct Answer: D

  https://cloud.google.com/appengine/docs/standard/go/config/appref

  "App Engine calculates the number of instances necessary to serve your current application traffic based on scaling settings such as target_cpu_utilization and target_throughput_utilization. Setting min_idle_instances specifies the number of

  instances to run in addition to this calculated number. For example, if App Engine calculates that 5 instances are necessary to serve traffic, and min_idle_instances is set to 2, App Engine will run 7 instances (5, calculated based on traffic,

  plus 2 additional per min_idle_instances)."

• Question 219:

  You have a development project with appropriate IAM roles defined. You are creating a production project and want to have the same IAM roles on the new project, using the fewest possible steps. What should you do?

  A. Use gcloud iam roles copy and specify the production project as the destination project.

  B. Use gcloud iam roles copy and specify your organization as the destination organization.

  C. In the Google Cloud Platform Console, use the `create role from role' functionality.

  D. In the Google Cloud Platform Console, use the `create role' functionality and select all applicable permissions.

  Correct Answer: A

  Reference: https://cloud.google.com/sdk/gcloud/reference/iam/roles/copy It's at project level and Iam role copy

• Question 220:

  You have an application that looks for its licensing server on the IP 10.0.3.21. You need to deploy the licensing server on Compute Engine. You do not want to change the configuration of the application and want the application to be able to reach the licensing server. What should you do?

  A. Reserve the IP 10.0.3.21 as a static internal IP address using gcloud and assign it to the licensing server.

  B. Reserve the IP 10.0.3.21 as a static public IP address using gcloud and assign it to the licensing server.

  C. Use the IP 10.0.3.21 as a custom ephemeral IP address and assign it to the licensing server.

  D. Start the licensing server with an automatic ephemeral IP address, and then promote it to a static internal IP address.

  Correct Answer: A

  IP 10.0.3.21 is internal by default, and to ensure that it will be static non-changing it should be selected as static internal ip address.
