Question 01
What characterizes an ICMP (ping) flood attack?
A Overwhelming a target with a high rate of ICMP Echo Request packets so it consumes bandwidth answering with Echo RepliesB Reflecting ICMP packets off a broadcast address to amplify trafficC Sending ICMP packets with the source and destination set to the victim's own addressD Sending a single ICMP packet larger than 65,535 bytes to crash the stack
Question 02
How do CDN and scrubbing-center architectures help absorb and mitigate large DDoS attacks?
A They encrypt all inbound packets so floods cannot be interpretedB They reflect excess traffic back to the botnet C2 serversC They distribute traffic across globally dispersed capacity and filter malicious flows before clean traffic reaches the originD They disable the origin server until the attack subsides
Question 03
A SYN flood attack succeeds primarily by exploiting which weakness in the TCP handshake?
A The server reassembles overlapping IP fragments and crashesB The server forwards source-routed packets around the firewallC The server echoes oversized ICMP packets back to spoofed broadcast addressesD The server allocates state for each half-open connection and its backlog queue fills before handshakes complete
