Total Questions 260
Question: 2
Lightweight Access Point Protocol or LWAPP is the name of a protocol that can control multiple
Wi-Fi wireless access points at once. How does the Cisco WCS know what has happened in an
LWAPP system when an AP’s interface goes down and then comes up again?

A. The Cisco WCS polls the APs and when the AP is unreachable, reports “Max retransmissions
reached on AP “.
B. The AP sends a linkDown then linkUp trap to the Cisco WCS; these are two of the six traps
defined in RFC 1215, A Convention for Defining Traps for use with the SNMP.
C. The AP cannot send a linkDown trap, as per RFC 1215, because the link is down; when the
link comes back up, the AP sends a linkup trap to the Cisco WLC, which then forwards the
trap to the Cisco WCS.
D. The Cisco WLC sends a trap to the Cisco WCS when it detects that an AP is down.

Answer: D
Question: 3
When using the enterprise-based authentication method for WPA2, a bidirectional handshake
exchange occurs between the client and the authenticator. Which five options will be the resu
of that exchange by use of controller based network? (Choose five.)

A. proof that each side is alive
B. creation of the Pairwise Transient Key
C. distribution of the Group Transient Key
D. binding of a Pairwise Master Key at the client and the controller
E. distribution of the Pairwise Master key for caching at the access point
F. a bidirectional exchange of a nonce used for key generation

Answer: A, B, C, D, F

Question: 62
Which statements are true about noise in an 802.11b/g environment (2.4-GHz)?

A. Noise is defined as a 2.4-GHz signal that is not in an 802.11 DSSS format but is in the
frequency range of the access point’s configured channel.
B. Microwave Oven, Cordless Phones, Jammers
C. Any signal that the access point cannot decode is considered noise.
D. 802.11 2.4-GHz frequency-hopping radio

Answer: A, B, C, D

Question: 63
In the process of deploying a Cisco 7921G wireless IP phone within the Cisco Unified Wireless
Network, which feature will be implemented between the phone and the access point to mitigate
one-way audio?

A. NMSP
B. DTPC
C. DCA and TPC
D. AKM

Answer: B

Question: 64
Which statement correctly describes preambles?

A. It may be necessary to configure an AP for long preambles, because some clients are not
capable of using short preambles.
B. Support for short preambles is mandatory.
C. It may be necessary to configure an AP for short preambles, because some clients do not
understand the additional information transmitted in long preambles.
D. For maximum throughput for both types of cards, short preambles should be turned off when
there is a mixture of 802.11b and 802.11g clients.

Question: 65
What is the reason that interference is generally more of an issue at the receiver than the
transmitter?

A. Signal levels at the receiver are logarithmically less than signal levels at the transmitter.
B. There are more receivers than transmitters.
C. Signal levels at the transmitter are logarithmically less than signal levels at the receiver.
D. It is unusual in wireless to receive and transmit at the same time, therefore the receiver can’t
detect the interference.

Answer: A

Question: 66
Which feature should be provisioned on all controllers in order for Radio Resource Management
to operate correctly amongst multiple controllers in which APs are able to hear each other?

A. the same mobility group

B. the same ASCII RF group name
C. Layer 2 LWAPP only
D. the same WEP Key

Answer: B

Question: 68
Cisco Client Management Frame Protection is running on a mobility group with two controllers.
For the following options, which two MFP requirements protect the network? (Choose two.)

A. requires the use of a nonbroadcast SSID
B. requires CCXv5
C. implements the validation of wireless management frames
D. forces clients to authenticate, using a secure EAP method only

Answer: B, C

Question: 69
How to differ EAP-TLS from Microsoft PEAP?

A. EAP-TLS requires a client certificate.
B. EAP-TLS does not require a certificate.
C. Both EAP-TLS and Microsoft PEAP require client certificates but Microsoft PEAP is described
in RFC 2716.
D. Microsoft PEAP is more secure.

Answer: A

Question: 245
What is the reason that Cisco recommends using Tftpd32 version 3.0 or
later when upgrading wireless LAN controller software to release 4.1 or later?

A. Tftpd32 is Cisco Compatible Extensions version 4 compliant
B. Tftpd32 supports TFTP file transfers larger than 32 MB
C. Tftpd32 is a component of CiscoWorks LMS
D. Tftpd32 supports EoIP tunneling which is required for remote Cisco WLC upgrades

Answer: B

Question: 247
How to deliver the 802.11i Pairwise Master Key to the client supplicant during 802.1X
authentication?

A. encrypted with the EAPOL Key Encryption Key
B. via a secure LWAPP control channel
C. unencrypted
D. it is not transmitted

Answer: D

Question: 260
Which two descriptions are correct about Dynamic Frequency Selection? (Choose two.)

A. DFS is fully supported on all Cisco Aironet 1130, 1240, and 1250 Series Access Points.
B. After radar has been detected on a DFS-enabled channel, it cannot be used for 30 minutes.
C. The Rogue Location Discovery Protocol and rogue containment are not supported for
channels on which DFS is enabled.
D. The minimum legal transmit power is greater for some 5-GHz channels than for others. When
a DFS event causes the controller to randomly select a 5-GHz channel on which power is
restricted, the controller automatically increases transmit power to comply with power limits for
that channel.

Answer: B, C
