Which two data encoding techniques are supported by gRPC? (Choose two.)

XML is not natively or commonly used as a data encoding technique in gRPC due to its verbosity and parsing overhead compared to Protobuf.

gRPC officially supports JSON as a data encoding format, especially for interoperability with web browsers and RESTful services, often via gRPC-JSON transcoding or helper libraries.

ASCII is a character encoding scheme, not a structured data serialization format used by gRPC for message payload exchange.

Protocol Buffers (Protobuf) is the primary, default, and highly efficient data serialization format designed specifically for gRPC, providing a schema-driven approach for defining service interfaces and message structures.

YAML is a human-friendly data serialization format but is not natively supported or commonly used for gRPC message encoding.
