Question 1

You recently developed an application that monitors a large number of stock prices. You need to configure Pub/Sub to receive a high volume messages and update the current stock price in a single large in-memory database The downstream service needs only the most up-to-date prices in the in-memory database to perform stock trading transactions Each message contains three pieces of information

* Stock symbol

* Stock price

* Timestamp for the update

How should you set up your Pub/Sub subscription?

ACreate a pull subscription with both ordering and exactly-once delivery turned off

BCreate a pull subscription with exactly-once delivery enabled

CCreate a push subscription with exactly-once delivery enabled

DCreate a push subscription with both ordering and exactly-once delivery turned off

Answer : C

Question 2

You are a developer at a large corporation You manage three Google Kubernetes Engine clusters. Your team's developers need to switch from one cluster to another regularly without losing access to their preferred development tools. You want to configure access to these clusters using the fewest number of steps while following Google-recommended best practices. What should you do?

AAsk the developers to use Cloud Shell and run gcloud container clusters get-credentials to switch to another cluster.

BAsk the developers to open three terminals on their workstation and use kubecrt1 config to configure access to each cluster.

CAsk the developers to install the gcloud CLI on their workstation and run gcloud container clusters get-credentials to switch to another cluster

DIn a configuration file, define the clusters users, and contexts Email the file to the developers and ask them to use kubect1 config to add cluster, user and context details.

Question 3

You have a web application that publishes messages to Pub/Sub. You plan to build new versions of the application locally and need to quickly test Pub/Sub integration tor each new build. How should you configure local testing?

ARun the gclcud config set api_endpoint_overrides/pubsub https: / 'pubsubemulator.googleapi3.com. coin/ command to change the Pub/Sub endpoint prior to starting the application

BIn the Google Cloud console, navigate to the API Library and enable the Pub/Sub API When developing locally, configure your application to call pubsub.googleapis com

CInstall Cloud Code on the integrated development environment (IDE) Navigate to Cloud APIs, and enable Pub/Sub against a valid Google Project ID. When developing locally, configure your application to call pubsub.googleapis com

DInstall the Pub/Sub emulator using gcloud and start the emulator with a valid Google Project ID. When developing locally, configure your application to use the local emulator by exporting the fuhsub emulator Host variable

Answer : C

Question 4

You are supporting a business-critical application in production deployed on Cloud Run. The application is reporting HTTP 500 errors that are affecting the usability of the application. You want to be alerted when the number of errors exceeds 15% of the requests within a specific time window. What should you do?

ANavigate to the Cloud Run page in the Google Cloud console, and select the service from the services list.
Use the Metrics tab to visualize the number of errors for that revision and refresh the page daily.

BCreate a Cloud Function that consumes the Cloud Monitoring API Use Cloud Composer to trigger the Cloud
Function daily and alert you if the number of errors is above the defined threshold.

CCreate an alerting policy in Cloud Monitoring that alerts you if the number of errors is above the defined
threshold.

DCreate a Cloud Function that consumes the Cloud Monitoring API Use Cloud Scheduler to trigger the Cloud
Function daily and alert you if the number of errors is above the defined threshold

Answer : B

Question 5

You have an application running in a production Google Kubernetes Engine (GKE) cluster. You use Cloud Deploy to automatically deploy your application to your production GKE cluster. As part of your development process: you are planning to make frequent changes to the applications source code and need to select the tools to test the changes before pushing them to your remote source code repository. Your toolset must meet the following requirements:

* Test frequent local changes automatically.

* Local deployment emulates production deployment.

Which tools should you use to test building and running a container on your laptop using minimal resources'?

ATerraform and kubeadm

BDocker Compose and dockerd

CMinikube and Skaffold

Dkaniko and Tekton
