Question 1.
Which authentication type defined by IEEE 802.11 utilizes a challenge text packet when associating to an AP?
A. Open authentication
B. EAP-TLS authentication
C. EAP-MD5 authentication
D. Shared-key authentication
Answer: D
Explanation:
Shared Key Authentication
1) The client sends an Authentication to Access point
2) Access Point sends an authentication response. The authentication response from the access point to the client is sent containing "challenge" text. This packet is unencrypted.
3) The client then uses the text from the authentication response to form another authentication packet, which will be encrypted using one of the client's WEP keys, and sends this as a response to the access point.
4) Access Point will then compare the encrypted "challenge" text against the access point's own copy of the encrypted "challenge" text. If the encrypted text is the same, then the access point allows the client to the WLAN.
Shared Key Authentication is considered less secure than OPEN Authentication because of the challenge text packet. Because this packet is sent unencrypted and then returned as an encrypted packet, it may be possible to capture both packets and determine the stream cipher.

Question 2.
What are three components of WAP (Version 1)? (Choose three)
A. LEAP
B. 48-bit IV
C. 802.1X authentication
D. 256-bit AES encryption cipher
E. Per-packet keying and Message Integrity Check
Answer: B, C, E
Question 3.
Which "cipher" is configured on the Cisco Aironet Access Point to enable WPA?
A. CK IP
B. CCKM
C. WEP 128
D. CKIP + CMIC
Answer: A
Explanation:
To enable WPA on an access point, an appropriate Cipher (or combination of ciphers) must be chosen. TKIP is the cipher used for WPA compliant devices. The following are valid WPA ciphers:
1) TKIP
2) TKIP + WEP 128 bit
3) TKIP + WEP 40 bit
Also note that when using WPA encryption on an access point, Encryption Key 1 must not be used- as the WPA key negotiation mechanism uses this key position in the AP to transfer authentication data to the client.
Question 4.
Which three are mechanisms for guarding against Basic 802.11 WEP key vulnerabilities? (Choose three)
A. WPA
B. Cisco CK IP (CKIP)
C. Message Integrity Check
D. Use of two WEP keys on the AP
E. String authentication passwords
Answer: A, B, C
Question 5.
Local Authentication Service on the Cisco Access Point allows a maximum of how many users?
A. 10
B. 25
C. 50
D. 100
Answer: C
Explanation:
IEEE 802.1X local authentication can support the authentication of up to 50 accounts for a given deployment in the local Cisco LEAP authentication database on the access point.
One account is equal to one user name and password. The configuration of the IEEE 802.1X local authentication database can be centrally managed with the Cisco Works WLSE 2.x management appliance. The access point with the IEEE 802.1X local authentication service does not need to be dedicated to the IEEE 802.1X local authentication service. This access point can function as a regular access point in addition to providing IEEE 802.1X local authentication.

Question 6
Which two types of packets are forwarded through an AP prior to a client being authenticated with server-based authentication? (Choose two)
A. DHCP packets
B. Multicast data packets
C. EAP authentication packets
D. 802.11 authentication
