NEW QUESTION # 27
You are designing a deployment technique for your applications on Google Cloud. As part Of your deployment planning, you want to use live traffic to gather performance metrics for new versions Of your applications. You need to test against the full production load before your applications are launched. What should you do?
- A. Use shadow testing with continuous deployment.
- B. Use canary testing with rolling updates deployment,
- C. Use canary testing with continuous deployment.
- D. Use A/B testing with blue/green deployment.
Answer: A
Explanation:
Explanation
The correct answer is B. Use shadow testing with continuous deployment.
Shadow testing is a deployment technique that involves routing a copy of the live traffic to a new version of the application, without affecting the production environment. This way, you can gather performance metrics and compare them with the current version, without exposing the new version to the users. Shadow testing can help you test against the full production load and identify any issues or bottlenecks before launching the new version. You can use continuous deployment to automate the process of deploying the new version after it passes the shadow testing.

NEW QUESTION # 29
You support a stateless web-based API that is deployed on a single Compute Engine instance in the europe-west2-a zone . The Service Level Indicator (SLI) for service availability is below the specified Service Level Objective (SLO). A postmortem has revealed that requests to the API regularly time out. The time outs are due to the API having a high number of requests and running out memory. You want to improve service availability. What should you do?
- A. Set up additional service instances in other zones and use them as a failover in case the primary instance is unavailable.
- B. Change the specified SLO to match the measured SLI.
- C. Set up additional service instances in other zones and load balance the traffic between all instances.
- D. Move the service to higher-specification compute instances with more memory.
Answer: C
NEW QUESTION # 30
You support a user-facing web application. When analyzing the application's error budget over the previous six months, you notice that the application has never consumed more than 5% of its error budget in any given time window. You hold a Service Level Objective (SLO) review with business stakeholders and confirm that the SLO is set appropriately. You want your application's SLO to more closely reflect its observed reliability.
What steps can you take to further that goal while balancing velocity, reliability, and business needs? (Choose two.)
- A. Announce planned downtime to consume more error budget, and ensure that users are not depending on a tighter SLO.
- B. Add more serving capacity to all of your application's zones.
- C. Tighten the SLO match the application's observed reliability.
- D. Implement and measure additional Service Level Indicators (SLIs) fro the application.
- E. Have more frequent or potentially risky application releases.
Answer: A,D
Explanation:
Explanation

- A. Configure a Helm chart repository server to run in Google Kubernetes Engine (GKE) with Cloud Storage bucket as the storage backend
- B. Store public and private charts in OCI format by using Artifact Registry
- C. Store public and private charts by using GitHub Enterprise with Google Workspace as the identity provider
- D. Store public and private charts by using Git repository Configure Cloud Build to synchronize contents of the repository into a Cloud Storage bucket Connect Helm to the bucket by using https: // [bucket]
.srorage.googleapis.com/ [holnchart] as the Helm repository
Answer: B
Explanation:
Explanation
The best option for managing all charts uniformly, with native access control and VPC Service Controls is to store public and private charts in OCI format by using Artifact Registry. Artifact Registry is a service that allows you to store and manage container images and other artifacts in Google Cloud. Artifact Registry supports OCI format, which is an open standard for storing container images and other artifacts such as Helm charts. You can use Artifact Registry to store public and private charts in OCI format and manage them uniformly. You can also use Artifact Registry's native access control features, such as IAM policies and VPC Service Controls, to secure your charts and control who can access them.

NEW QUESTION # 37
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, the serving 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?
- A. A freshness SLI: the proportion of widgets that have been updated within the last 10 minutes
- B. An availability SLI: the ratio of healthy microservices to the total number of microservices
- C. A latency SLI: the ratio of microservice calls that complete in under 100 ms to the total number of microservice calls
- D. A quality SLI: the ratio of non-degraded responses to total responses
