Options :

A : Analyze VPC flow logs along the path of the request.

B : Investigate the Liveness and Readiness probes for each service.

C : Create a Dataflow pipeline to analyze service metrics in real time

D : Use a distributed tracing framework such as OpenTelemetry or Stackdriver Trace.

Answer: C

Question 2

What is the definition of SLI in the context of SRE terminology?

Options :

A : The expectation that a service is available or reliable for a certain target level over a specific period

B : Expecting the service to be available or expecting the service to meet a specific amount of latency, throughput, or freshness, or any other characteristic that is critical to the user journey

C : The expectation that a service will meet a pre-defined customer expectation, the failure of which results in a refund or credits

D : The ability of an application or service to perform a specific function within a specific time without failures

Answer: B

Question 3

Your company runs services by using Google Kubernetes Engine (GKE). The GKE clusters in the development environment run applications with verbose logging enabled. Developers view logs by using the kubect1 logs command and do not use Cloud Logging. Applications do not have a uniform logging structure defined. You need to minimize the costs associated with application logging while still collecting GKE operational logs. What should you do?

Options :

A : Run the gcloud container clusters update --logging SYSTEM command for the development cluster.

B : Run the gcloud container clusters update logging=WORKLOAD command for the development cluster.

C : Run the gcloud logging sinks update _Defau1t --disabled command in the project associated with the development environment.

D : Add the severity >= DEBUG resource. type "k83 container" exclusion filter to the Default logging sink in the project associated with the development environment.

Answer: A

Question 4

As a Social impact investment platform company, you are deploying an application that requires access to sensitive information. What measures should you take to ensure that this information is encrypted and the chances of exposure are minimal in case of a breach? Additionally, which Google Cloud Services can be leveraged to achieve this goal?

Options :

A : Incorporate a Single sign-on (SSO) system to the application and ensure that no secrets are revealed to the application.

B : Frequently rotate encryption keys and keep them stored in Cloud Key Management Service (KMS).

C : During the creation of the instance, use an encrypted configuration management system to insert the secret.

D : Create a continuous build pipeline that generates various versions of the secret for every application instance.

Answer: B

Question 5

Your development team has created a new version of their service’s API. You need to deploy the new versions of the API with the least disruption to third-party developers and end users of third-party installed applications. What should you do?

Options :

A : Introduce the new version of the API.Announce deprecation of the old version of the API.Deprecate the old version of the API.Contact remaining users of the old API.Provide best effort support to users of the old API.Turn down the old version of the API.

B : Announce deprecation of the old version of the API.Introduce the new version of the API.Contact remaining users on the old API.Deprecate the old version of the API.Turn down the old version of the API.Provide best effort support to users of the old API.

C : Announce deprecation of the old version of the API.Contact remaining users on the old API.Introduce the new version of the API.Deprecate the old version of the API.Provide best effort support to users of the old API.Turn down the old version of the API.

D : Introduce the new version of the API.Contact remaining users of the old API.Announce deprecation of the old version of the API.Deprecate the old version of the API.Turn down the old version of the API.Provide best effort support to users of the old API.
