Accepted Answer

David should change the access password to his router. This is the password used to log into the router's administrative interface, not the Wi-Fi password. If attackers are reconfiguring his router, it means they have access to this interface. Changing the Wi-Fi password, SSID, or guest access settings would not prevent unauthorized access to the router's settings.

Accepted Answer

Repetitive strain injury (RSI) is a physical health diagnosis that is on the rise due to the increased use of technology, especially for people who use computers extensively. RSI is a condition that affects the muscles, nerves, and tendons in the upper extremities, including the wrists, forearms, and hands, causing pain, numbness, and tingling. The repetitive movements associated with typing or using a mouse for extended periods of time can lead to RSI. Cyberstalking, cyberbullying, and technology addiction are not physical health diagnoses, but rather psychological or social problems related to technology use.

Question 17

Mariella is ready to study at a local coffee shop before her final exam in two days.As she settles in, the manager announces an evil twin attack is in progress and everyone should ensure they're connected to the shop's own Wi-Fi.Mariella checks her phone and finds it has already connected to the attacker's network.What should she do to protect her phone in the future?

Accepted Answer

Mariella should make sure she is connected to a legitimate network in the future to avoid the attack. Deleting the coffee shop's Wi-Fi from her saved networks or changing her Wi-Fi password won't prevent her phone from connecting to the attacker's network if it's still in range. Using the phone's cellular signal instead of Wi-Fi is an option, but it may not be reliable or feasible in all situations.

Question 18

How is a worm different from a Trojan?

Accepted Answer

The main difference between a worm and a Trojan is their method of spread. A worm spreads through a network, usually by exploiting vulnerabilities in software or by tricking users into executing it. In contrast, a Trojan hides inside another program or masquerades as a legitimate file to trick users into installing it. Therefore, the correct answer is C - a worm spreads through a network, whereas a Trojan hides inside another program. Choices A, B, and D are incorrect because they either incorrectly describe the behavior of a worm or confuse it with a different type of malware.
