Which two statements are true about implementing an API-First strategy?
The API is to be developed first before any UI or new business logic are created.
It generally is assumed that SOAP/WSDL are the key specifications for defining the API.
The code to execute business logic needs to exist and be exposed as an API first before you build a strategy around it.
You define the API definition/contract first before any work on its implementation or any applications that use it, allowing teams to work in parallel.

Question 2

Which three are characteristics of Device Virtualization?
Oracle Internet of Things (IoT) Cloud Service does not support Device Virtualization.
You can monitor each device endpoint’s health, performance, and location via the client software library API, or with REST calls made to those devices.
You can collect data from your devices using APIs delivered with Oracle Internet of Things (IoT) Cloud Service Client Software Libraries or Oracle IoT Cloud Service Gateway.
The APIs provided enable you to send telemetry messages and device data from your devices to Oracle Internet of Things (IoT) Cloud Service, control your devices, and deploy applications to your gateway devices.
Devices used are not real. They are virtual devices and linked with Oracle Internet of Things (IoT) CS.
