Question

A flood of inbound connections from various global locations suggests what kind of attack?

Options

AA denial-of-service attack
BA worm
CAn email phishing
DA virus

Explanation

A flood of inbound connections from various global locations suggests a distributed denial-of- service (DDoS) attack. In this type of attack, a large number of compromised machines (or devices) are used to flood a target system with traffic, overwhelming it and causing it to become inaccessible. The traffic may come from different sources, making blocking or mitigating the attack harder (because it becomes harder to distinguish legitimate from attacking traffic). A worm is a self-replicating malware that can spread to other systems but does not necessarily involve a flood of connections. A virus is a type of malware that attaches itself to a legitimate program and replicates when that program is executed. A Smurf attack is a type of DDoS attack that involves spoofing the source IP address and sending a flood of ICMP packets to a network's broadcast address, causing all hosts in the network to respond and flood the target with traffic
