To answer this question, you need to understand web protocol recording levels and which one generates the web_submit_data function.
The web protocol recording level that always generates the web_submit_data function is the URL level.
Let's go through each option to understand why it is correct or incorrect:
Option A) ICA - This option is incorrect because the ICA protocol is used for remote desktop and application virtualization, not web protocol recording.
Option B) URL - This option is correct because when recording at the URL level, the web_submit_data function is always generated. The web_submit_data function is used to submit data to the server.
Option C) RDP - This option is incorrect because the RDP protocol is used for remote desktop connections, not web protocol recording.
Option D) HTML - This option is incorrect because the HTML protocol does not generate the web_submit_data function. The HTML protocol is used for recording events on web pages.
The correct answer is B) URL. This option is correct because recording at the URL level always generates the web_submit_data function.
