210-250 · Question #155

What two are examples of UDP-based attacks? (Choose two.)

The correct answer is B. SQL slammer C. UDP flooding. SQL Slammer and UDP flooding are UDP-based attacks - SQL Slammer propagated entirely over UDP, while UDP flooding directly overwhelms targets with high-volume UDP traffic.

Why each option

SQL Slammer and UDP flooding are UDP-based attacks - SQL Slammer propagated entirely over UDP, while UDP flooding directly overwhelms targets with high-volume UDP traffic.

ASYN flood

A SYN flood is a TCP-based attack that exploits the TCP three-way handshake by sending unanswered SYN packets to exhaust server connection tables - it depends entirely on TCP state tracking, not UDP.

BSQL slammerCorrect

SQL Slammer (also known as Sapphire) was a worm that exploited a buffer overflow in Microsoft SQL Server 2000 and propagated entirely over UDP port 1434 using small, rapid packets that caused widespread network congestion globally in 2003.

CUDP floodingCorrect

UDP flooding is a volumetric DoS attack that sends large numbers of UDP packets to random ports on a target host, forcing the system to process each datagram and send ICMP port-unreachable responses, consuming both CPU resources and available bandwidth.

DMAC address flooding

MAC address flooding is a Layer 2 attack that overwhelms a switch's CAM table with forged MAC addresses, forcing the switch to broadcast traffic out all ports - it operates at the data link layer and does not use UDP.
