A DevOps engineer maintains a Terraform configuration that creates multiple Azure virtual machines. They have a map of VM names to their CPU utilization percentages, e.g., { vm1 = 85, vm2 = 92, vm3 = 78 }. They need to output the name of the VM with the highest utilization. Which expression should they use?

lookup(var.vm_utilization, max(values(var.vm_utilization)))

element(keys(var.vm_utilization), max(values(var.vm_utilization)))

keys(var.vm_utilization)[index(values(var.vm_utilization), max(values(var.vm_utilization)))]

max(values(var.vm_utilization))

A platform team generates unique resource names for each environment using a local value. They have a list of environment codes like ["dev", "staging", "prod"] and need to produce a single string like "dev-staging-prod-resources" for a naming convention. They also need to ensure the final string is lowercase. Which expression achieves this?

join("-", concat(["resources"], var.env_codes))

lower(join("-", concat(var.env_codes, ["resources"])))

lower(join("-", var.env_codes)) + "-resources"

join("-", concat(var.env_codes, ["resources"]))

A developer needs to create a list of strings that combines a prefix with each element from an existing list. They have `var.names = ["app1", "app2"]` and want to produce `["prod-app1", "prod-app2"]`. Which expression achieves this?

[for n in var.names : "prod-${n}"]
