Explanation:

A DDoS (Distributed Denial of Service) attack uses multiple compromised devices ("zombies") to flood a target system. A single-device DoS attack is easier to trace to the source, so hackers prefer DDoS for anonymity. Other options are incorrect: DDoS doesn’t create firewalls, unidirectional networks, or coordination issues (it relies on coordinated zombie activity).

launching a DoS attack on a computer system from a single computer is easy to trace
