Question 1

You want to create ''fully baked'' or ''golden'' Compute Engine images for your application. You need to bootstrap your application to connect to the appropriate database according to the environment the application is running on (test, staging, production). What should you do?

AEmbed the appropriate database connection string in the image. Create a different image for each environment.

BWhen creating the Compute Engine instance, add a tag with the name of the database to be connected. In your application, query the Compute Engine API to pull the tags for the current instance, and use the tag to construct the appropriate database connection string.

CWhen creating the Compute Engine instance, create a metadata item with a key of ''DATABASE'' and a value for the appropriate database connection string. In your application, read the ''DATABASE'' environment variable, and use the value to connect to the appropriate database.

DWhen creating the Compute Engine instance, create a metadata item with a key of ''DATABASE'' and a value for the appropriate database connection string. In your application, query the metadata server for the ''DATABASE'' value, and use the value to connect to the appropriate database.

Answer : D

Question 2

You are monitoring a web application that is written in Go and deployed in Google Kubernetes Engine. You notice an increase in CPU and memory utilization. You need to determine which source code is consuming the most CPU and memory resources. What should you do?

ADownload, install, and start the Snapshot Debugger agent in your VM. Take debug snapshots of the functions that take the longest time. Review the call stack frame, and identify the local variables at that level in the stack.

BImport the Cloud Profiler package into your application, and initialize the Profiler agent. Review the generated flame graph in the Google Cloud console to identify time-intensive functions.

CImport OpenTelemetry and Trace export packages into your application, and create the trace provider.
Review the latency data for your application on the Trace overview page, and identify where bottlenecks are occurring.

DCreate a Cloud Logging query that gathers the web application's logs. Write a Python script that calculates the difference between the timestamps from the beginning and the end of the application's longest functions to identity time-intensive functions.

Answer : B

Question 3

You are deploying your application to a Compute Engine virtual machine instance. Your application is

configured to write its log files to disk. You want to view the logs in Stackdriver Logging without changing the

application code.

What should you do?

AInstall the Stackdriver Logging Agent and configure it to send the application logs.

BUse a Stackdriver Logging Library to log directly from the application to Stackdriver Logging.

CProvide the log file folder path in the metadata of the instance to configure it to send the application logs.

DChange the application to log to /var/log so that its logs are automatically sent to Stackdriver Logging.

Answer : A

Question 4

You need to containerize a web application that will be hosted on Google Cloud behind a global load balancer with SSL certificates. You don't have the time to develop authentication at the application level, and you want to offload SSL encryption and management from your application. You want to configure the architecture using managed services where possible What should you do?

AHost the application on Compute Engine, and configure Cloud Endpoints for your application.

BHost the application on Google Kubernetes Engine and use Identity-Aware Proxy (IAP) with Cloud Load Balancing and Google-managed certificates.

CHost the application on Google Kubernetes Engine, and deploy an NGINX Ingress Controller to handle authentication.

DHost the application on Google Kubernetes Engine, and deploy cert-manager to manage SSL certificates.

Answer : B

Question 5

In order for HipLocal to store application state and meet their stated business requirements, which database service should they migrate to?

ACloud Spanner

BCloud Datastore

CCloud Memorystore as a cache

DSeparate Cloud SQL clusters for each region

Answer : D

Question 6

You are deploying your application to a Compute Engine virtual machine instance with the Stackdriver

Monitoring Agent installed. Your application is a unix process on the instance. You want to be alerted if the unix process has not run for at least 5 minutes. You are not able to change the application to generate metrics or logs.

Which alert condition should you configure?

AUptime check

BProcess health

CMetric absence

DMetric threshold

Answer : B

Question 7

Your company has created an application that uploads a report to a Cloud Storage bucket. When the report is uploaded to the bucket, you want to publish a message to a Cloud Pub/Sub topic. You want to implement a solution that will take a small amount to effort to implement. What should you do?

AConfigure the Cloud Storage bucket to trigger Cloud Pub/Sub notifications when objects are modified.

BCreate an App Engine application to receive the file; when it is received, publish a message to the Cloud Pub/Sub topic.

CCreate a Cloud Function that is triggered by the Cloud Storage bucket. In the Cloud Function, publish a message to the Cloud Pub/Sub topic.

DCreate an application deployed in a Google Kubernetes Engine cluster to receive the file; when it is received, publish a message to the Cloud Pub/Sub topic.

Answer : C
