Explanation

A Distributed Denial of Service (DDoS) attack is characterized by a large volume of traffic originating from many different sources (compromised hosts or botnets) targeting a single system or network. The key indicator here is 'many sources,' which distinguishes DDoS from a regular DoS attack. A rogue access point would not generate a multi-source traffic spike. A compromised IDS would affect monitoring, not generate inbound traffic. DNS poisoning would redirect traffic but not cause a multi-source spike against the administrator's own network.
