Cisco CCNA 200-301 Practice Question

Implementing heuristics-based malware detection is effective against unknown malware, including zero-day threats, because it analyzes behavior and patterns rather than relying on known virus signatures. Signature-based antivirus software cannot detect new, unknown malware without existing signatures. Enforcing strict password policies enhances account security but does not prevent malware infections. Applying regular software updates is important but does not protect against vulnerabilities for which patches are not yet available.
