Which of the following tools can be used for stress testing of a Web server? Each correct answer represents a complete solution. Choose two.

Internet bots can be programmed to simulate large numbers of concurrent users making repeated HTTP requests to a web server, effectively generating artificial load for stress testing purposes.

Spyware is malicious software designed to covertly collect and exfiltrate user data; it generates no meaningful outbound load against a web server and serves no purpose in stress testing.

Anti-virus software is a host-based defensive tool for detecting and removing malware; it cannot generate network traffic or simulate user load against a web server.

Scripts can automate the rapid and repeated submission of HTTP requests to a target web server, allowing testers to control request volume and rate to measure server behavior under stress.
