802.1X and EAP Security Quiz

1. What does mutual authentication in EAP mean?

Both client and server verify each other's identity

Multiple servers authenticate the same client

Clients authenticate through two different methods

The network authenticates multiple devices simultaneously

2. Which statement about 802.1X is true?

It only works on wireless networks

It provides port-based access control on both wired and wireless networks

It encrypts all data traffic automatically

It requires a VPN connection to function

3. What is the primary purpose of the RADIUS protocol in an 802.1X network?

To encrypt wireless signals

To transmit authentication credentials securely

To manage DHCP addresses

To monitor network bandwidth

4. In EAP-TLS, what does the client certificate verify?

The user's identity to the authentication server

The network's SSID

The authenticator's IP address

The RADIUS server's location

5. What is a key advantage of using 802.1X with certificate-based EAP methods?

Eliminates the need for passwords

Provides mutual authentication and strong encryption

Reduces network latency

Simplifies user enrollment

6. Which EAP method allows password-based authentication within an encrypted tunnel?

EAP-TLS

EAP-MD5

EAP-PEAP

EAP-SIM

7. In 802.1X, the uncontrolled port allows which type of traffic?

All network traffic

Only authenticated user data

Only 802.1X authentication frames

Only encrypted traffic

8. What is the role of the authentication server in 802.1X?

Monitors network traffic and blocks threats

Verifies user credentials and authorizes access

Encrypts all network communications

Assigns IP addresses to authenticated devices

9. Which EAP variant tunnels a second EAP exchange inside an encrypted TLS tunnel?

EAP-TLS

EAP-TTLS

EAP-PEAP

EAP-IKEv2

10. In an 802.1X deployment, what happens to traffic before authentication is successful?

All traffic is allowed

Only DHCP and DNS traffic is permitted

Traffic is encrypted but not authenticated

All traffic is blocked except authentication frames

11. What is the primary purpose of 802.1X port-based access control?

Authenticate users and devices before network access is granted

Encrypt all wireless traffic on the network

Monitor network bandwidth usage

Block all unauthorized IP addresses

12. Which EAP method is considered the most secure for wireless enterprise networks?

EAP-MD5

EAP-TTLS

EAP-TLS

EAP-SIM

13. In 802.1X, what is the controlled port?

The port used for RADIUS communication

The port that allows data traffic after authentication

The port reserved for administrative access

The port used for DHCP requests

14. What is the main vulnerability of EAP-MD5?

It does not support mutual authentication

It requires client certificates

It only works on wired networks

It uses weak encryption algorithms

15. Which protocol is commonly used with 802.1X to communicate between authenticators and authentication servers?

LDAP

RADIUS

Kerberos

TACACS

16. In EAP-PEAP, what does the outer tunnel protect?

The server certificate only

The inner authentication exchange

The user's IP address

The network SSID

17. Which EAP method uses TLS encryption to protect the authentication exchange?

EAP-MD5

EAP-TLS

EAP-TTLS

EAP-PEAP

18. What does EAP stand for?

Encryption Authentication Protocol

Extensible Authentication Protocol

Enterprise Access Point

Ethernet Authentication Process

19. Which component in 802.1X acts as the intermediary between the supplicant and the authentication server?

Authenticator

RADIUS server

Supplicant

Network gateway

20. In an 802.1X architecture, what role does the supplicant play?

Authenticates the network server

Requests network access and provides credentials

Grants or denies network access based on authentication

Encrypts all data traffic between devices
