You have declared a variable called var.list which is a list of objects that all have an attribute id . Which options will produce a list of the IDs? Choose two correct answers.

Question

Options

• A[ var.list [ * ] , id ]
• B[ for o in var.list : o.Id ]
• Cvar.list[*].id
• D{ for o in var.llst : o => o.id }

• A
  8% (2)
• B
  79% (19)
• D
  13% (3)

Explanation

Two syntaxes produce a flat list of attribute values in Terraform. C - var.list[*].id - uses the splat expression, which iterates over all elements of var.list and extracts the id attribute from each, returning a list. B - [ for o in var.list : o.id ] - uses a for expression inside a tuple constructor, explicitly iterating over each object and projecting its id attribute into a new list. Option A has invalid syntax. Option D uses double curly braces and the o => o.id map syntax, which would produce a map, not a list.
