Google Google Certifications ASSOCIATE-CLOUD-ENGINEER Questions & Answers

• Question 191:

  You created a Google Cloud Platform project with an App Engine application inside the project. You initially configured the application to be served from the us-central region. Now you want the application to be served from the asianortheast1 region. What should you do?

  A. Change the default region property setting in the existing GCP project to asia-northeast1.

  B. Change the region property setting in the existing App Engine application from us-central to asia-northeast1.

  C. Create a second App Engine application in the existing GCP project and specify asia-northeast1 as the region to serve your application.

  D. Create a new GCP project and create an App Engine application inside this new project. Specify asia-northeast1 as the region to serve your application.

  Correct Answer: D

  Option D is correct, as there can be only one App Engine application inside a project . C is incorrect, as GCP can't have two app engine applications.

• Question 192:

• Question 194:

  You need to create a new billing account and then link it with an existing Google Cloud Platform project. What should you do?

  A. Verify that you are Project Billing Manager for the GCP project. Update the existing project to link it to the existing billing account.

  B. Verify that you are Project Billing Manager for the GCP project. Create a new billing account and link the new billing account to the existing project.

  C. Verify that you are Billing Administrator for the billing account. Create a new project and link the new project to the existing billing account.

  D. Verify that you are Billing Administrator for the billing account. Update the existing project to link it to the existing billing account.

  Correct Answer: B

  Billing Account Administrator

  (roles/billing.admin) Manage billing accounts (but not create them).

  Billing Account User

  (roles/billing.user)

  When granted in conjunction with the Project Owner role or Project Billing Manager role, provides access to associate projects with billing accounts.

• Question 195:

  You are deploying an application to a Compute Engine VM in a managed instance group. The application must be running at all times, but only a single instance of the VM should run per GCP project. How should you configure the instance group?

  A. Set autoscaling to On, set the minimum number of instances to 1, and then set the maximum number of instances to 1.

  B. Set autoscaling to Off, set the minimum number of instances to 1, and then set the maximum number of instances to 1.

  C. Set autoscaling to On, set the minimum number of instances to 1, and then set the maximum number of instances to 2.

  D. Set autoscaling to Off, set the minimum number of instances to 1, and then set the maximum number of instances to 2.

  Correct Answer: A

  In my GCP console, I created a managed instance group for each answer. For each answer I deleted the instance that was created as a simple test to prove or disprove each answer.

  In answer A, another instance was created after I deleted the instance In answer B, no other instance was created after I deleted the instance In answer C, another instance was created after I deleted the instance In answer D, no other instance was created after I deleted the instance

  My observation is A is the correct Answer.

  A - Correct - It correctly solves the problem with only a single instance at one time B - Incorrect - Does not fit the requirement because AFTER the deletion of the instance, no other instance was created C - Incorrect - It creates another instance after the delete HOWEVER it 2 VM's could be created even if the target is exceeded D - Incorrect - Does not fit the requirement because AFTER the deletion of the instance, no other instance was created

• Question 196:

  You need to monitor resources that are distributed over different projects in Google Cloud Platform. You want to consolidate reporting under the same Stackdriver Monitoring dashboard. What should you do?

  A. Use Shared VPC to connect all projects, and link Stackdriver to one of the projects.

  B. For each project, create a Stackdriver account. In each project, create a service account for that project and grant it the role of Stackdriver Account Editor in all other projects.

  C. Configure a single Stackdriver account, and link all projects to the same account.

  D. Configure a single Stackdriver account for one of the projects. In Stackdriver, create a Group and add the other project names as criteria for that Group.

  Correct Answer: C

  First of all D is incorrect, Groups are used to define alerts on set of resources(such as VM instances, databases, and load balancers). FYI tried adding Two projects into a group it did not allowed me as the "AND"/"OR" criteria for the group

  failed with this combination of resources.

  C is correct because,

  When you intially click on Monitoring(Stackdriver Monitoring) it creates a workspac(a stackdriver account) linked to the ACTIVE(CURRENT) Project from which it was clicked.

  Now if you change the project and again click onto Monitoring it would create an another workspace(a stackdriver account) linked to the changed ACTIVE(CURRENT) Project, we don't want this as this would not consolidate our result into a

  single dashboard(workspace/stackdriver account).

  If you have accidently created two diff workspaces merge them under Monitoring > Settings > Merge Workspaces > MERGE.

  If we have only one workspace and two projects we can simply add other GCP Project under

  Monitoring > Settings > GCP Projects > Add GCP Projects.

  In both of these cases we did not create a GROUP, we just linked GCP Project to the workspace(stackdriver account).

• Question 197:

  You want to send and consume Cloud Pub/Sub messages from your App Engine application. The Cloud Pub/Sub API is currently disabled. You will use a service account to authenticate your application to the API. You want to make sure your application can use Cloud Pub/Sub. What should you do?

  A. Enable the Cloud Pub/Sub API in the API Library on the GCP Console.

  B. Rely on the automatic enablement of the Cloud Pub/Sub API when the Service Account accesses it.

  C. Use Deployment Manager to deploy your application. Rely on the automatic enablement of all APIs used by the application being deployed.

  D. Grant the App Engine Default service account the role of Cloud Pub/Sub Admin. Have your application enable the API on the first connection to Cloud Pub/Sub.

  Correct Answer: A

  Quickstart: using the Google Cloud Console

  This page shows you how to perform basic tasks in Pub/Sub using the Google Cloud Console.

  Note: If you are new to Pub/Sub, we recommend that you start with the interactive tutorial.

  Before you begin

  Set up a Cloud Console project.

  Set up a project

  Click to:

  Create or select a project.

  Enable the Pub/Sub API for that project.

  You can view and manage these resources at any time in the Cloud Console.

  Install and initialize the Cloud SDK.

  Note: You can run the gcloud tool in the Cloud Console without installing the Cloud SDK. To run the gcloud tool in the Cloud Console, use Cloud Shell .

  resourcemanager.projects.get

  resourcemanager.projects.list

  storage.buckets.* storage.objects.*

• Question 199:

  You have an object in a Cloud Storage bucket that you want to share with an external company. The object contains sensitive data. You want access to the content to be removed after four hours. The external company does not have a Google account to which you can grant specific user-based access privileges. You want to use the most secure method that requires the fewest steps. What should you do?

  A. Create a signed URL with a four-hour expiration and share the URL with the company.

  B. Set object access to `public' and use object lifecycle management to remove the object after four hours.

  C. Configure the storage bucket as a static website and furnish the object's URL to the company. Delete the object from the storage bucket after four hours.

  D. Create a new Cloud Storage bucket specifically for the external company to access. Copy the object to that bucket. Delete the bucket after four hours have passed.

  Correct Answer: A

  Signed URLs are used to give time-limited resource access to anyone in possession of the URL, regardless of whether they have a Google account. https://cloud.google.com/storage/docs/access-control/signed-urls
