C. 1 Attach a local SSD lo the first instance disk
2. Execute an rsync command every hour where the target is a persistent SSD disk attached to the second instance
3. In case of a zone outage, use the second instance

For this question, refer to the Dress4Win case study.
Dress4Win has asked you for advice on how to migrate their on-premises MySQL deployment to the cloud.
They want to minimize downtime and performance impact to their on-premises solution during the migration.
Which approach should you recommend?

A. Setup a MySQL replica server/slave in the cloud environment, and configure it for asynchronous replication from the MySQL master server on-premises until cutover.

B. Create a dump of the on-premises MySQL master server, and then shut it down, upload it to the cloud environment, and load into a new MySQL cluster.

C. Create a dump of the MySQL replica server into the cloud environment, load it into: Google Cloud Datastore, and configure applications to read/write to Cloud Datastore at cutover.

D. Create a new MySQL cluster in the cloud, configure applications to begin writing to both on-premises and cloud MySQL masters, and destroy the original cluster at cutover.

정답: A

문제5
You are developing your microservices application on Google Kubernetes Engine. During testing, you want to validate the behavior of your application in case a specific microservice should suddenly crash. What should you do?

A. Destroy one of the nodes of the Kubernetes cluster to observe the behavior.

B. Use Istio's fault injection on the particular microservice whose faulty behavior you want to simulate.

C. Add a taint to one of the nodes of the Kubernetes cluster. For the specific microservice, configure a pod anti-affinity label that has the name of the tainted node as a value.

D. Configure Istio's traffic management features to steer the traffic away from a crashing microservice.

문제7
You are a cloud architect for a financial services company that is migrating to Google Cloud. The company needs to create a multi-tenant landing zone for its business units and must adhere to strict regulatory compliance. The security team wants to use VPC Service Controls to create a zero-trust perimeter. However, the business wants you to accelerate the migration to quickly start developing new applications. How can you design a deployment and release management process to meet these competing requirements?

A. Grant each business unit autonomy to create their own CI/CD pipelines and infrastructure, and conduct periodic security audits to ensure compliance with VPC Service Controls. Enforce IAM inheritance from the folder level.

B. Establish a centralized CI/CD pipeline with automated policy and security validation at each stage.Define the VPC Service Controls perimeter in a " dry run " mode in the development environment to audit and test for violations. Turn on VPC Service Controls perimeter for the production environment.

C. Implement a centralized CI/CD pipeline that uses pre-approved Infrastructure as Code (IaC) templates.
To maximize agility, allow business units to clone and modify these templates freely, and use a phased rollout for VPC Service Controls.

D. Use a single CI/CD pipeline for all business units that deploys directly to a single, shared project. Rely on IAM permissions to isolate workloads within the project. Turn on VPC Service Controls perimeter for the production environment.
