An organization is deploying OpenStack in a multi-tenant environment. They need to ensure that tenants can create their own networks and manage their own VMs, but they must not be able to affect other tenants' resources. Which combination of OpenStack services and features is required to achieve this isolation?

Glance for images and Keystone for authentication, with no network isolation.

Nova for compute and Cinder for storage, with no additional configuration.

Keystone for authentication and authorization, and Neutron with tenant network isolation.

Neutron for networking and Nova for compute, but without Keystone.

A team is using Terraform to manage a production environment. They have a remote backend configured with state locking. A developer accidentally runs `terraform apply` from a local directory that has an outdated state file. The apply fails because the state file is locked by another process. What is the most appropriate next step?

Wait for the lock to be released and then re-run `terraform plan` and `terraform apply`.

Delete the local state file and re-run `terraform init`.

Run `terraform apply` with the `-lock=false` flag to bypass the lock.

Force unlock the state using `terraform force-unlock` with the lock ID.

A company uses Terraform to manage resources in both AWS and Google Cloud. They have a single Terraform configuration that defines resources in both providers. When they run `terraform plan`, they notice that Terraform wants to create resources in both clouds. What is the primary reason Terraform can manage resources across multiple providers in a single configuration?

Terraform uses a common configuration language that is natively understood by all cloud providers.

Terraform uses a single API that works with all cloud providers.

Terraform stores all resources in a single state file that is shared across providers.

Terraform uses provider plugins that abstract the APIs of different cloud providers.
