Ace Your Associate-Cloud-Engineer Google Cloud Certified Exam

A managed instance group (MIG) is a group of identical virtual machines (VMs) that you can manage as a single entity. You can use a MIG to deploy and maintain a stateless application that runs directly on VMs. A MIG can automatically scale the number of VMs based on the load or a schedule. A MIG can also automatically heal the VMs if they become unhealthy or unavailable. A MIG is suitable for applications that need to run on VMs rather than containers or serverless platforms.

B is incorrect because Kubernetes Engine is a managed service for running containerized applications on a cluster of nodes. It is not necessary to use Kubernetes Engine if the application does not use containers and can run directly on VMs.

C is incorrect because Cloud Functions is a serverless platform for running event-driven code in response to triggers. It is not suitable for applications that need to run continuously and handle HTTP requests.

D is incorrect because Cloud Run is a serverless platform for running stateless containerized applications. It is not suitable for applications that do not use containers and can run directly on VMs.

Choosing a compute option for Google Cloud

Storage Solution: Cloud Storage is the Google-managed, highly durable, and scalable object storage solution ideal for storing unstructured documents like invoices.

Tiering/Cost Optimization:

For frequent access (past 6 months), the initial storage class should be Standard (lowest latency, higher storage cost).

For archived/audit purposes only (after 6 months), the access frequency is extremely low. Coldline Storage is the lowest-cost storage class designed for data accessed infrequently (once a quarter or less), minimizing overall cost.

Automation: Object Lifecycle Management is the native Cloud Storage feature used to automatically transition objects between storage classes (e.g., Standard $\to$ Coldline) based on time (e.g., after 6 months), fulfilling the requirements for automation and cost minimization.

gcloud deployment-manager deployments create creates deployments based on the configuration file. (Infrastructure as code). All the configuration related to the artifacts is in the configuration file. This command correctly creates a cluster based on the provided cluster.yaml configuration file.
