Which type of block fetches or computes information for use elsewhere in a Terraform configuration?

Rationale for Correct Answer (A):

data blocks fetch information from providers (like AMI IDs, network info) that can be used in other resources.

Analysis of Incorrect Options:

B. local: Stores values, doesn’t fetch external data.

C. resource: Defines managed infrastructure, not read-only data.

D. provider: Configures connection to APIs, not data fetching.

Key Concept:

Data sources are read-only queries into existing infrastructure.
