A team is designing an API for a medical IoT device that sends patient vitals. The API must support both a web dashboard and a mobile app. The team is debating between JSON and XML. Which consideration is most important for this decision?

JSON is not suitable for real-time data.

JSON is easier to parse in JavaScript, which is used by the web dashboard.

XML is required for all medical APIs.

An organization manages IoT devices across multiple sites with varying network reliability. They need to remotely monitor and update devices, but some sites have intermittent connectivity. Which management strategy is most resilient?

Use a direct HTTPS connection from the management server to each device

Use a store-and-forward mechanism where devices queue commands and status updates when offline

Use a single central server that devices poll every hour

Require devices to maintain a persistent WebSocket connection to the management server

Which security measure is essential to protect data transmitted between an IoT device and a web server over the internet?

Implementing TLS/SSL encryption via HTTPS

Disabling authentication on the API

Using only IP address filtering

Using plain HTTP for all communications
