Question 20

You support a high-traffic web application with a microservice architecture. The home page of the application displays multiple widgets containing content such as the current weather, stock prices, and news headlines. The main serving thread makes a call to a dedicated microservice for each widget and then lays out the homepage for the user. The microservices occasionally fail; when that happens, theserving thread serves the homepage with some missing content. Users of the application are unhappy if this degraded mode occurs too frequently, but they would rather have some content served instead of no content at all. You want to set a Service Level Objective (SLO) to ensure that the user experience does not degrade too much. What Service Level Indicator {SLI) should you use to measure this?

Options:

A quality SLI: the ratio of non-degraded responses to total responses

An availability SLI: the ratio of healthy microservices to the total number of microservices

A freshness SLI: the proportion of widgets that have been updated within the last 10 minutes

A latency SLI: the ratio of microservice calls that complete in under 100 ms to the total number of microservice calls

Question 21

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:

Look for the agent's test log entry in the Logs Viewer.

Install the most recent version of the Stackdriver agent.

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

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

Erik

Hey, I have passed my exam using Cramkey Dumps?

Freyja Oct 17, 2024

Really, what are they? All come in your pool? Please give me more details, I am going to have access their subscription. Please brother, give me more details.

Mariam

Do anyone think Cramkey questions can help improve exam scores?

Katie Nov 2, 2024

Absolutely! Many people have reported improved scores after using Cramkey Dumps, and there are also success stories of people passing exams on the first try. I already passed this exam. I confirmed above questions were in exam.

Robin

Cramkey is highly recommended.

Jonah Oct 16, 2024

Definitely. If you're looking for a reliable and effective study resource, look no further than Cramkey Dumps. They're simply wonderful!

Honey

I highly recommend it. They made a big difference for me and I'm sure they'll help you too. Just make sure to use them wisely and not solely rely on them. They should be used as a supplement to your regular studies.

Antoni Oct 25, 2024

Good point. Thanks for the advice. I'll definitely keep that in mind.

Annabel

I recently used them for my exam and I passed it with excellent score. I am impressed.

Amirah Oct 28, 2024

I passed too. The questions I saw in the actual exam were exactly the same as the ones in the Cramkey Dumps. I was able to answer the questions confidently because I had already seen and studied them.

Question 22

Your company runs applications in Google Kubernetes Engine (GKE). Several applications rely on ephemeral volumes. You noticed some applications were unstable due to the DiskPressure node condition on the worker nodes. You need

to identify which Pods are causing the issue, but you do not have execute access to workloads and nodes. What should you do?

Options:

Check the node/ephemeral_storage/used_bytes metric by using Metrics Explorer.

Check the metric by using Metrics Explorer.

Locate all the Pods with emptyDir volumes. use the df-h command to measure volume disk usage.

Locate all the Pods with emptyDir volumes. Use the du -sh * command to measure volume disk usage.

Question 23

Your team deploys applications to three Google Kubernetes Engine (GKE) environments development staging and production You use GitHub reposrtones as your source of truth You need to ensure that the three environments are consistent You want to follow Google-recommended practices to enforce and install network policies and a logging DaemonSet on all the GKE clusters in those environments What should you do?

Options:

Use Google Cloud Deploy to deploy the network policies and the DaemonSet Use Cloud Monitoring to trigger an alert if the network policies and DaemonSet drift from your source in the repository.

Use Google Cloud Deploy to deploy the DaemonSet and use Policy Controller to configure the network policies Use Cloud Monitoring to detect drifts from the source in the repository and Cloud Functions tocorrect the drifts

Use Cloud Build to render and deploy the network policies and the DaemonSet Set up Config Sync to sync the configurations for the three environments
