NEW QUESTION # 51
Which of the following can best protect a computer when an infected file has been downloaded?
- A. Anti-malware
- B. Permissions
- C. Patching
- D. Firewall
Answer: A
Explanation:
Anti-malware software is specifically designed to detect, quarantine, and remove malicious software from a system. It is the most appropriate tool for protecting a computer after a suspicious or infected file is downloaded.
"Anti-malware software scans downloaded files and running processes to identify and remove malicious software, providing real-time protection against viruses, trojans, and spyware." - CompTIA ITF+ Study Guide Other options:
B . Firewall - Prevents unauthorized access but doesn't clean infections C . Patching - Prevents exploitation of known vulnerabilities, not infection removal D . Permissions - Limit access but do not remove malware Correct answer: A
NEW QUESTION # 52
A user's internet speed is slow. The user logs in to the router's administrator portal and sees that unauthorized devices are connected to the network. Which of the following actions should the user take to prevent unauthorized use of the network?
- A. Reset the router.
- B. Decrease the Wi-Fi signal range.
- C. Change the password.
- D. Call the internet provider's support line.
Answer: C
Explanation:
Changing the router's password (particularly the Wi-Fi password) prevents unauthorized users from reconnecting to the network. It's the most immediate and effective response.
"One of the most effective ways to secure a wireless network is by changing the default and existing passwords to prevent unauthorized access." - CompTIA ITF+ Security Topics Calling support may help but doesn't address the issue directly.
Decreasing signal range may reduce but not eliminate access.
Resetting the router is more disruptive and unnecessary if the password can be changed.
Correct answer: C

NEW QUESTION # 59
Which of the following is used to determine whether users accessed inappropriate online content?
- A. Location tracking
- B. System logs
- C. Web browser history
- D. Cookie data
Answer: C
Explanation:
The web browser history stores records of websites that a user has visited. This is typically the most straightforward and accessible method for determining whether users accessed inappropriate or unauthorized online content. The CompTIA ITF+ documentation explains:
"Web browsers maintain a history of visited URLs, which can be used for monitoring and auditing user activity, including detecting policy violations regarding internet usage." System logs are broader and generally capture system or security events.
Cookies store session and tracking data but don't always show what content was accessed.
Location tracking helps with geolocation, not content monitoring.
Therefore, the correct choice is D.
