Remote Procedure Call (RPC) API calls are a way of invoking a function or service on a remote device over the network. Here are the two characteristics of RPC API calls:

Parameters can be passed to the calls: One of the primary benefits of using RPC API calls is that they allow parameters to be passed to the remote function or service being invoked. This enables the caller to pass information to the function or service and receive a response. The parameters passed to the call will vary depending on the specific function or service being invoked.
They call a single function or service: RPC API calls are designed to invoke a single function or service at a time. This is different from other API protocols, such as REST API, which may allow for multiple functions or services to be invoked in a single call. RPC API calls are typically used in situations where a single action needs to be performed on a remote device, such as retrieving configuration information or making changes to the device's settings.

Therefore, the correct answers are:

C. Parameters can be passed to the calls.
E. They call a single function or service.
