Question 1

What is the best practice for securing sensitive data on a mobile device when connecting to public Wi-Fi networks?

Correct Answer: Use a VPN

The best practice for securing sensitive data on a mobile device when connecting to public Wi-Fi networks is to use a VPN (Virtual Private Network). Here's why:

1. A VPN encrypts your internet traffic, making it unreadable to potential hackers or eavesdroppers on the public network.
2. It masks your IP address and location, providing an additional layer of privacy.
3. VPNs create a secure tunnel for your data to travel through, protecting it from various cyber threats associated with public Wi-Fi.

Regarding the other options:

Enabling airplane mode would disconnect you from all wireless networks, making it impossible to use the internet at all.

Turning off Wi-Fi and using cellular data can be more secure than using public Wi-Fi, but it doesn't provide the same level of protection as a VPN and may result in high data usage charges.

Clearing browser cache and cookies doesn't provide any real-time protection against threats on public Wi-Fi networks. While it's a good practice for privacy, it doesn't secure your data during transmission.

Question 2

Jason's mobile device has been freezing when he uses his banking app. He suspects there could be a security issue. What should Jason's first step be?

Correct Answer: Update all apps and the operating system on his mobile device

Updating all apps and the operating system on the mobile device is the best first step when suspecting a security issue. This ensures that any known vulnerabilities or bugs in the apps or OS are patched, which could resolve the freezing issue and improve security. Continuing to use the app without addressing the potential security problem is not advisable. Removing the banking app does not address the underlying issue and prevents access to mobile banking. Resetting the online banking password, while a good security practice, does not directly resolve the freezing issue or the suspected security problem with the mobile device itself.

Question 3

A company recently issued new smartphones to its employees. Kayla notices that her device frequently disconnects from the secure office Wi-Fi. To resolve this issue, what should she do?

Correct Answer: Contact IT support

The best course of action is to contact IT support. They are equipped to diagnose and resolve technical issues with company-provided devices, including Wi-Fi connectivity problems. Turning off Wi-Fi would prevent the smartphone from connecting to the office network entirely. Using a personal hotspot instead of the office Wi-Fi could potentially violate company security policies and expose sensitive data. Resetting the device may temporarily resolve the issue but does not address the underlying cause of the Wi-Fi disconnections. Kayla should allow IT professionals to properly troubleshoot the problem to ensure her smartphone remains securely connected to the office network.
