   A gaming company's authentication server receives a sudden 40 Gbps flood of UDP packets from thousands of distinct IP addresses. The packets are all small (under 100 bytes), target a single port, and contain no valid game-client payloads. The company's 10 Gbps internet link is saturated, and legitimate players cannot log in. Which type of DDoS attack is this, and what is the primary impact?

   • AProtocol-based SYN flood; the server's connection table is exhausted
   • BLegitimate flash crowd; the sudden spike is due to a new game release
   • CApplication-layer HTTP flood; the server's CPU is exhausted parsing requests
   • DVolumetric UDP flood; the attack saturates the internet link, causing complete service unavailability
