AWS Local Zones are an extension of an AWS Region, designed to bring AWS infrastructure closer to end-users in select metropolitan areas. They are intended for running latency-sensitive applications and are connected to the parent AWS Region through a low-latency network link. This allows resources in the Local Zone to interact with other AWS services in the parent Region seamlessly, enabling customers to deploy applications with low latency in specific geographic areas while still having access to the full range of AWS services available in the parent Region. The correct answer is C, as it accurately describes the purpose and connectivity of AWS Local Zones.
