An organization uses Terraform to manage network devices from multiple vendors. The team wants to ensure that all engineers use the same provider versions and that the configuration is reproducible. What should the team do?

Add a `required_providers` block with version constraints and commit the dependency lock file

Run `terraform init` on every engineer's machine before each apply

Set the `TF_PROVIDER_VERSION` environment variable in each engineer's shell

Use `terraform get` to fetch the latest provider versions

A network engineer manages a set of Juniper devices using Terraform. After editing a resource block in the configuration, the engineer runs `terraform plan` and sees that Terraform intends to replace the device instead of updating it in place. The engineer wants to minimize disruption and keep the same device. What should the engineer do?

Delete the resource from the state file and re-import it after applying

Run `terraform apply -replace` to force an in-place update

Modify the resource's `lifecycle` block to set `create_before_destroy = true`

Check the provider documentation for a force-new argument and adjust the configuration to avoid changing it

A company uses Terraform with a remote backend that supports state locking. During a routine `terraform apply`, the operation fails with an error indicating that the state is locked. The engineer suspects a previous apply was interrupted. What should the engineer do first?

Wait for the lock to expire automatically

Force unlock the state using the lock ID from the error message

Run `terraform apply` again with the `-lock=false` flag

Delete the state file and re-import all resources

A network administrator writes a Terraform configuration to manage a Juniper device. The configuration includes a variable for the device's hostname. The administrator wants to output the device's IP address after the resource is created. What should the administrator add to the configuration?

A `variable` block that references the resource attribute

A `resource` block with a `provisioner` that prints the IP

An `output` block that references the resource attribute

A `data` source that queries the device
