If a user receives an email with an attachment labeled 'document.exe', what security risk should they consider before opening it?
- A. The file is too large to download
- B. The file extension .exe indicates it's an executable program that could potentially contain malware
- C. The file will automatically backup their data
- D. The file will drain the computer's battery
Answer: B. The file extension .exe indicates it's an executable program that could potentially contain malware

Consider a situation where a company discovers malware on multiple computers across their network. Which factor indicates they likely had inadequate protection, and what multi-layered approach would have been better?
- A. They used too strong passwords; passwords are sufficient protection
- B. They had only antivirus without firewall, allowing network-based malware to enter freely; a comprehensive approach including firewall, antivirus, regular updates, and user training is necessary
- C. They performed backups too frequently; backups cause malware infections
- D. Their GUI was outdated; updating the interface prevents malware
Answer: B. They had only antivirus without firewall, allowing network-based malware to enter freely; a comprehensive approach including firewall, antivirus, regular updates, and user training is necessary
Single-layer security is insufficient; effective protection requires firewalls to prevent unauthorized access, antivirus for threat detection, timely updates, and user awareness.

A tech support person must recover deleted files and determine if malware was involved. Which of these factors would be most crucial to investigate first?
- A. Whether disk cleanup was recently performed
- B. The file extensions and timestamps of remaining files, plus firewall logs to identify suspicious network activity
- C. The computer's monitor resolution settings
- D. Whether the keyboard is wireless or wired
Answer: B. The file extensions and timestamps of remaining files, plus firewall logs to identify suspicious network activity
File extensions and timestamps help identify suspicious file modifications or additions, while firewall logs reveal unauthorized access attempts; together they indicate malware involvement.
