In the context of the Web Layer tests on the Cisco ThousandEyes platform, what is the significance of round$-$robin scheduling in the configuration of a Page Load test or Transaction test, and how does it affect the execution of these tests?

Round$-$robin scheduling distributes test execution across specified intervals, preventing simultaneous test runs from multiple agents and ensuring a balanced load and precise timing measurement.

Round$-$robin scheduling ensures equal CPU and memory resource allocation among all running tests, enhancing server performance.

Round$-$robin scheduling is used for sequential database querying to optimize data retrieval times during the tests.

Round$-$robin scheduling prioritizes tests based on their network bandwidth requirements, ensuring high$-$bandwidth tests are executed first.
