Developing Applications for Cisco Webex and Webex Devices (DEVWBX) — Question 24

With CE 9.8 and above, which two statements are correct when an application is sending and receiving data over a connection established with an xAPI interface?
(Choose two.)

Answer options

• A. All Serial, SSH, and WebSockets can be used to send and receive data.
• B. HttpClient can be used to send requests but not receive responses.
• C. HttpFeedback is the only option to receive data.
• D. The HttpClient command can be used to send requests and read responses over HTTP.
• E. WebSockets is the only option to send and receive data.

Correct answer: B, D

Explanation

The correct answers are B and D because HttpClient is indeed used to send requests and can read responses over HTTP, making D true. Option B accurately states that while HttpClient sends requests, it does not receive responses. The other options are incorrect as they either claim incorrect capabilities of the technologies or limit the options unnecessarily.
