Zorluk: OrtaDeploying and Configuring Managed Database Instances

A cloud engineer needs to deploy a Google Cloud Bigtable instance named `telemetry-db` to store high-throughput IoT sensor data. The project deployment specification requires a cluster named `telemetry-c1` located in the `us-central1-a` zone, provisioned with 3 nodes using SSD storage. Which `gcloud` command correctly provisions this managed database instance?

  1. gcloud bigtable instances create telemetry-db --display-name="Telemetry DB" --cluster=telemetry-c1 --cluster-zone=us-central1-a --cluster-num-nodes=3 --cluster-storage-type=SSDCevap
  2. B
    gcloud sql instances create telemetry-db --database-version=POSTGRES_14 --tier=db-custom-4-15360 --zone=us-central1-a --storage-type=SSD
  3. C
    gcloud bigtable instances create telemetry-db --display-name="Telemetry DB" --zone=us-central1-a --nodes=3 --storage-type=SSD
  4. D
    gcloud sql instances create telemetry-db --tier=db-n1-standard-2 --assign-ip --authorized-networks=0.0.0.0/0

Cevap

Execute `gcloud bigtable instances create telemetry-db --display-name="Telemetry DB" --cluster=telemetry-c1 --cluster-zone=us-central1-a --cluster-num-nodes=3 --cluster-storage-type=SSD` to provision the Cloud Bigtable instance and cluster.
The correct option uses `gcloud bigtable instances create` and supplies all required parameters: instance ID (`telemetry-db`), `--display-name`, `--cluster`, `--cluster-zone=us-central1-a`, `--cluster-num-nodes=3`, and `--cluster-storage-type=SSD`. This fulfills all specified operational requirements.

Adım Adım Çözüm

1
Identify the target database technology
Cloud Bigtable is required for high-throughput IoT time-series sensor data.
Cloud Bigtable is Google Cloud's managed NoSQL wide-column database service for large-scale analytical and operational workloads.
2
Identify the required gcloud CLI command group
Use `gcloud bigtable instances create` instead of `gcloud sql instances create`.
Cloud Bigtable resources are managed under the `gcloud bigtable` CLI group.
3
Verify required CLI flags for instance and cluster creation
Specify `--cluster`, `--cluster-zone`, `--cluster-num-nodes`, and `--cluster-storage-type`.
Creating a Bigtable instance requires defining its initial cluster properties using the `--cluster-*` flag family.
