Core Principle of Zero Trust

Which statement best describes the core principle of Zero Trust Architecture?

A Trust all users inside the network by default but verify external users.

B Trust users based on their device type only.

C Trust no one, verify everyone regardless of location or network.

D Trust users after they have logged in once without further checks.

💡 Hint

Think about how Zero Trust treats users both inside and outside the network.

Zero Trust means never trusting any user or device by default, whether inside or outside the network. Verification is always required.

Zero Trust and Network Perimeters

What happens to the traditional network perimeter concept in Zero Trust Architecture?

A It is eliminated because trust is not based on location.

B It is strengthened with more firewalls and gates.

C It is expanded to include all connected devices automatically.

D It remains the same but with added encryption.

💡 Hint

Consider how Zero Trust treats internal and external network boundaries.

Zero Trust removes the idea of a trusted internal network perimeter and treats all access requests as untrusted until verified.

🚀 Application

Applying Zero Trust to User Access

In a Zero Trust model, what is the best way to control user access to sensitive data?

A Grant access based on user role and location without further checks.

B Allow access only after multi-factor authentication and continuous monitoring.

C Provide access once per day after a single login session.

D Grant access automatically if the user is on the company network.

💡 Hint

Think about how Zero Trust verifies users continuously, not just once.

Zero Trust requires strong authentication like multi-factor and ongoing monitoring to ensure access remains secure.

Zero Trust and Device Security

Which approach aligns best with Zero Trust principles when managing devices connecting to a corporate network?

A Require device health checks and compliance before granting access.

B Trust devices that have connected before without rechecking.

C Only block devices that are reported lost or stolen.

D Allow all devices that have antivirus software installed.

💡 Hint

Consider how Zero Trust treats devices before allowing access.

Zero Trust requires verifying device health and compliance every time before access is granted.

Zero Trust Impact on Incident Response

How does implementing Zero Trust Architecture improve an organization's ability to respond to security incidents?

A It removes the need for incident response teams by preventing all attacks.

B It slows down response because of complex access controls.

C It relies solely on automated tools without human intervention.

D It provides detailed visibility and limits attack spread, enabling faster containment.

💡 Hint

Think about how Zero Trust limits damage and helps detect threats quickly.

Zero Trust gives better visibility into user and device activity and limits lateral movement, helping teams contain incidents faster.
