A web browser, with an empty cache, is set to use persistent HTTP and can open up to $6$ parallel connections to a single server. A requested web page contains one main HTML file and $10$ embedded images (all hosted on the same server). What is the minimum number of TCP connections the browser will open to display the page completely?

The browser will open its maximum number of parallel connections ($6$) to the server. It will download the HTML file on one connection and then distribute the $10$ image requests across those same $6$ persistent connections as they become available. All $11$ objects are multiplexed over these $6$ connections, which are opened once and then reused.
