Question 1

Which of the following is the most effective way to protect sensitive data on a mobile device that is frequently used in public spaces?

Correct Answer: Enabling full device encryption

Enabling full device encryption is the most effective way to protect sensitive data on a mobile device used in public spaces. This method provides comprehensive protection for all data stored on the device, making it unreadable to unauthorized users even if the device is lost or stolen. Here's why this is the best option and why the others are less effective: 1. Full device encryption: This encrypts all data on the device, ensuring that even if someone gains physical access to the device, they cannot access the data without the encryption key. 2. Using a complex alphanumeric passcode: While this is a good security measure, it only protects against unauthorized access attempts and doesn't protect the data if the device is compromised or the passcode is bypassed. 3. Regularly updating the device's operating system: This is important for overall security but doesn't specifically protect sensitive data stored on the device. 4. Installing a third-party antivirus application: Antivirus software can help protect against malware but doesn't provide comprehensive protection for sensitive data stored on the device. In conclusion, full device encryption offers the highest level of protection for sensitive data, especially when the device is used in public spaces where the risk of loss or theft is higher.

Question 2

A user has connected their smartphone to a public WiFi hotspot. They experience slow internet access, and the device displays 'limited connectivity'. What should they do?

Correct Answer: Try connecting to another available network or connecting through mobile data.

A slow or limited internet connection on a public WiFi hotspot may indicate network congestion or weak signal. Connecting to another available network or using mobile data might fix the issue. The other options do not address the core problem and may cause further issues.

Question 3

A user is unable to connect their mobile device with their car's audio system via Bluetooth. Which accessory would best solve this issue?

Correct Answer: Acquire a Bluetooth receiver for the car audio

A Bluetooth receiver for the car audio would allow the user to connect their mobile device to the car's audio system via Bluetooth. Other accessories listed do not address the connectivity issue.
