Explanation
An Intrusion Detection and Prevention System (IDPS) serves the dual primary purpose of detecting and blocking malicious attacks. The 'detection' component (IDS) monitors network traffic and alerts on suspicious activity, while the 'prevention' component (IPS) actively blocks or drops malicious traffic in real time. Option A ('prevent existing threats') is vague and incomplete. Option C ('stop malicious code') describes antivirus/anti-malware more than IDPS. Option D ('detect attempts to connect') only describes a narrow subset of IDS functionality, not the full IDPS purpose.
