An agile team identifies a risk that a new technology might not scale. Which TWO actions represent an appropriate agile risk response?

Transfer the risk to the client by adding a disclaimer in the contract.

Create a 'Spike' story to prototype and test the technology in the next sprint.

Reprioritize the backlog to address the high-risk feature early (fail fast).

Wait until the end of the project to test scalability when the system is complete.

Increase the contingency reserve by 20%.
