Question 1

A user complains that they are frequently away from their desk and miss the 2FA prompt on their phone. What is the best way to modify 2FA to make it more convenient?

Correct Answer: Using a wearable device with push authentication

Using a wearable device with push authentication can improve convenience and ensure security by allowing the user to receive prompts even when away from their phone or desk. The other options may weaken security or not solve the user's issue.

Question 2

An employee receives a request to verify a login attempt to a corporate application. They did not initiate the login. What should the employee do?

Correct Answer: Deny the request and report the incident to IT security

If an employee receives a request to verify a login attempt to a corporate application that they did not initiate, the best course of action is to deny the request and report the incident to IT security. This is because the login attempt is likely unauthorized and could be an attempt to gain unauthorized access to corporate systems or data. Approving the request and changing the password would not address the underlying security issue and could enable the attacker to maintain access. Simply ignoring the request fails to take appropriate action to investigate and mitigate the potential threat.

Question 3

An employee received a new smartphone and wants to set up 2FA with their company's system. What should they do first?

Correct Answer: Install the company-approved authenticator app on their new smartphone.

To set up 2FA on a new smartphone, the employee should first install the company-approved authenticator app. This will allow them to generate tokens for two-factor authentication on their new device.
