The correct answer is A.

OBJ-1.1: A triple-homed firewall connects to three networks internal (private), external (internet/public), and a screened subnet (formerly called a demilitarized zone or DMZ). The screened subnet is used to host systems that require access from external hosts. Data zones describe the state and location of data to help isolate and protect it from unauthorized/inappropriate use-for example, as data transitions from raw storage, processing, production, and analytical use. Data zones are associated with data lakes and designed to help manage big data used by analysts and scientists for data exploration and discovery tasks. An availability zone is an individual data center within a region of a cloud service provider’s network. A staging environment is a pre-production enclave used for testing and development.
