Which attack represents the evasion technique of resource exhaustion?

SQL injection focuses on exploiting vulnerabilities in database input fields to gain unauthorized access to or manipulate data, not primarily to exhaust system resources.

A man-in-the-middle attack involves an attacker secretly relaying and possibly altering communication between two parties who believe they are directly communicating with each other, rather than exhausting resources.

Bluesnarfing is a Bluetooth attack that allows an attacker to access information on a device, such as calendars, contacts, and emails, without the owner's knowledge or permission, and is not a resource exhaustion technique.

Denial-of-service (DoS) attacks aim to make a system or network resource unavailable to legitimate users by overwhelming it with traffic or requests, thereby deliberately exhausting resources like network bandwidth, CPU cycles, memory, or connection tables.
