Question 1

You are running an application in a virtual machine (VM) using a custom Debian image. The image has the Stackdriver Logging agent installed. The VM has the cloud-platform scope. The application is logging information via syslog. You want to use Stackdriver Logging in the Google Cloud Platform Console to visualize the logs. You notice that syslog is not showing up in the "All logs" dropdown list of the Logs Viewer. What is the first thing you should do?

Options :

A : Look for the agent-s test log entry in the Logs Viewer.

B : Install the most recent version of the Stackdriver agent.

C : Verify the VM service account access scope includes the monitoring.write scope.

D : SSH to the VM and execute the following commands on your VM: ps ax I grep fluentd

Answer: D

Question 2

As a food delivery company, your team uses Cloud Build for all CI/CD pipelines. You want to use the kubectl builder for Cloud Build to deploy new images to Google Kubernetes Engine(GKE). You need to authenticate to GKE while minimizing development effort. What steps should you take?

Options :

A : To execute Cloud Build, generate a fresh service account with Container Developer privileges.

B : In the cloudbuild.yaml file, define the role of Container Developer for Cloud Build.

C : Grant the Cloud Build service account the role of a Container Developer.

D : In Cloud Build, add a distinct stage to fetch the service account credentials and transfer them to kubectl.

Answer: C

Question 3

You support a Node.js application running on Google Kubernetes Engine (GKE) in production. The application makes several HTTP requests to dependent applications. You want to anticipate which dependent applications might cause performance issues. What should you do?

Options :

A : Instrument all applications with Stackdriver Profiler.

B : Instrument all applications with Stackdriver Trace and review inter-service HTTP requests.

C :

Use Stackdriver Debugger to review the execution of logic within each application to instrument all applications.

D :

Modify the Node.js application to log HTTP request and response times to dependent applications. Use Stackdriver Logging to find dependent applications that are performing poorly.

Answer: B

Question 4

In a Personalized Nutrition Service company, the application is running on App Engine and is accessed globally through different devices. Which metric should be used in Cloud Monitoring for App Engine to determine the number of connections?

Options :

A : What does "tcp_ssl_proxy/new_connections" refer to?

B : The current status of the connections can be viewed at fiex/connections/current.

C : The current connections to a specific instance can be found at fiex/instance/connections/current.

D : The number of open connections for a TCP SSL proxy.

Answer: B

Question 5

The task at hand requires your team to design a new application that will be deployed in Google Kubernetes Engine (GKE). As part of the application design, you need to establish a monitoring system that will collect and consolidate various application-level metrics into a single location. To achieve this, your preference is to utilize Google Cloud Platform services while minimizing the setup process required for the monitoring system.

What actions do you need to take?

Options :

A : Publish various metrics from the application directly to the Stackdriver Monitoring API, and then observe these custom metrics in Stackdriver.

B : Emit all metrics in the form of application-specific log messages, pass these messages from the containers to the Stackdriver logging collector, and then observe metrics in Stackdriver.

C : Install the Cloud Pub/Sub client libraries, push various metrics from the application to various topics, and then observe the aggregated metrics in Stackdriver.

D : Install the OpenTelemetry client libraries in the application, configure Stackdriver as the export destination for the metrics, and then observe the application-s metrics in Stackdriver.

Answer: A
