You need to deploy an application on Google Cloud that must run on a Debian Linux
environment. The application requires extensive configuration in order to operate correctly. You
want to ensure that you can install Debian distribution updates with minimal manual
intervention whenever they become available. What should you do?
A. Create a Compute Engine instance template using the most recent Debian image. Create an
instance from this template, and install and configure the application as part of the startup
script. Repeat this process whenever a new Google-managed Debian image becomes available.
B. Create a Debian-based Compute Engine instance, install and configure the application, and
use OS patch management to install available updates.
C. Create an instance with the latest available Debian image. Connect to the instance via SSH,
and install and configure the application on the instance. Repeat this process whene - ANS B.

You have an application that runs in Google Kubernetes Engine (GKE). Over the last 2 weeks,
customers have reported that a specific part of the application returns errors very frequently.
You currently have no logging or monitoring solution enabled on your GKE cluster. You want to
diagnose the problem, but you have not been able to replicate the issue. You want to cause
minimal disruption to the application. What should you do?
A. 1. Update your GKE cluster to use Cloud Operations for GKE. 2. Use the GKE Monitoring
dashboard to investigate logs from affected Pods.

,B. 1. Create a new GKE cluster with Cloud Operations for GKE enabled. 2. Migrate the affected
Pods to the new cluster, and redirect traffic for those Pods to the new cluster. 3. Use the GKE
Monitoring dashboard to investigate logs from affected Pods.
C. 1. Update your GKE cluster to use Cloud Operations for GKE, and deploy Prometheus. 2. Set
an alert to tr - ANS A. 1. Update your GKE cluster to use Cloud Operations for GKE. 2. Use the

You need to deploy a stateful workload on Google Cloud. The workload can scale horizontally,
but each instance needs to read and write to the same POSIX filesystem. At high load, the
stateful workload needs to support up to 100 MB/s of writes. What should you do?
A. Use a persistent disk for each instance.
B. Use a regional persistent disk for each instance.
C. Create a Cloud Filestore instance and mount it in each instance.
D. Create a Cloud Storage bucket and mount it in each instance using gcsfuse. - ANS C. Create
a Cloud Filestore instance and mount it in each instance. Most Voted
Your company has an application deployed on Anthos clusters (formerly Anthos GKE) that is
running multiple microservices. The cluster has both Anthos ServiceMesh and Anthos Config
Management configured. End users inform you that the application is responding very slowly.
You want to identify the microservice that is causing the delay. What should you do?
A. Use the Service Mesh visualization in the Cloud Console to inspect the telemetry between
the microservices.
B. Use Anthos Config Management to create a ClusterSelector selecting the relevant cluster. On
the Google Cloud Console page for Google Kubernetes Engine, view the Workloads and filter on
the cluster. Inspect the configurations of the filtered workloads.
C. Use Anthos Config Management to create a namespaceSelector selecting the relevant cluster
namespace. On the Google Cloud Console page for Google Kubernetes Engine, visit the
workloads and filter on the na - ANS A. Use the Service Mesh visualization in the Cloud
Console to inspect the telemetry between the microservices.
You are working at a financial institution that stores mortgage loan approval documents on
Cloud Storage. Any change to these approval documents must be uploaded as a separate
approval file, so you want to ensure that these documents cannot be deleted or overwritten for
the next 5 years. What should you do?

, A. Create a retention policy on the bucket for the duration of 5 years. Create a lock on the
retention policy.
B. Create the bucket with uniform bucket-level access, and grant a service account the role of
Object Writer. Use the service account to upload new files.
C. Use a customer-managed key for the encryption of the bucket. Rotate the key after 5 years.
D. Create the bucket with fine-grained access control, and grant a service account the role of
Object Writer. Use the service account to upload new files. - ANS A. Create a retention policy
on the bucket for the duration of 5 years. Create a lock on the retention policy.
Your team will start developing a new application using microservices architecture on
Kubernetes Engine. As part of the development lifecycle, any code change that has been pushed
to the remote develop branch on your GitHub repository should be built and tested
automatically. When the build and test are successful, the relevant microservice will be
deployed automatically in the development environment. You want to ensure that all code
deployed in the development environment follows this process. What should you do?
A. Have each developer install a pre-commit hook on their workstation that tests the code and
builds the container when committing on the development branch. After a successful commit,
have the developer deploy the newly built container image on the development cluster.
B. Install a post-commit hook on the remote git repository that tests the code and builds the
container when code is pushed to the develop - ANS C. Create a Cloud Build trigger based on
the development branch that tests the code, builds the container, and stores it in Container
Registry. Create a deployment pipeline that watches for new images and deploys the new image
on the development cluster. Ensure only the deployment tool has access to deploy new
versions. (Most Voted)
Your operations team has asked you to help diagnose a performance issue in a production
application that runs on Compute Engine. The application is dropping requests that reach it
when under heavy load. The process list for affected instances shows a single application
process that is consuming all available CPU, and autoscaling has reached the upper limit of
instances. There is no abnormal load on any other related systems, including the database. You
want to allow production traffic to be served again as quickly as possible. Which action should
you recommend?
A. Change the autoscaling metric to agent.googleapis.com/memory/percent_used.
B. Restart the affected instances on a staggered schedule.
C. SSH to each instance and restart the application process.
