문제1

When preparing a floor plan graphic for use in predictive and manual site surveying, what calibration method will lead to the most accurate and reliable RF data?

A. Use the known size of a small object, such as a ceiling tile, and use a single instance of this object (e.g. a single ceiling tile) to scale the floor plan.

B. Calibrate the ceiling height of the floor plan first, then the survey software should be able to auto-calibrate the X and Y planes of the graphic.

C. Measure the width of an actual office doorway with a tape measure and use this value to calibrate against a doorway graphic.

D. With properly formatted .bmp and .png graphics, the site survey software should be able to extract the scale directly from the graphic data during import.

E. Use the longest available measurement (like a straight exterior wall) to calibrate the graphic's scale.

정답: E

문제2

You captured the wireless frame shown in the exhibit during a post-deployment verification site survey.

What can you tell the customer about this network?

A. This is a voice control packet, and the configuration looks normal, as voice control may or may not have a DSCP tag.

B. This is a video stream packet, and there is a QoS marking issue on the wired side, because the DSCP value should not be set to 0.

C. This is a video stream packet, and the configuration looks normal, as DSCP is always set to 0 when 802.11e QoS is specified at Layer 2.

D. This is a voice RTP packet, and its marking was downgraded from Voice to Video which is a sign of congestion issues.

정답: A

문제3

What is the purpose of DHCP Option 43, and how is it used with WLANs?

A. It provides clients with a temporary IP address on a restricted VLAN until 802.1X authentication is completed. Then the client receives its long-term IP address.

B. It supports vendor-specific IP address attributes for node discovery purposes. APs use Option 43 with vendor class identifiers to obtain the IP address of a centralized WLAN controller.

C. It integrates a DHCP server with AAA servers and user databases to dynamically assign IP addresses to client devices. During 802.1X, the AAA server uses Option 43 to notify the DHCP server what IP pool the client's address should be drawn from.

D. It provides IP address bindings for specific network nodes that require long-term IP address assignments. WLAN controllers are configured to use Option 43 to receive long-term IP address leases that are centrally managed with DHCP.

정답: B

문제4

Given: Assume that music on hold (MOH) features are unicast only.
What VoWiFi implementations require multicast packet delivery support by the WLAN infrastructure?

A. All VoWiFi implementations

B. FMC phones

C. VoWiFi soft phones

D. Flat (non-VLAN) VoWiFi implementations

E. Push-to-Talk VoWiFi phones

정답: E

문제5

Assuming an identical RF environment,

which one of these scenarios is most likely to lead to a client-to-AP link imbalance in which one-way communication results?

A. Option C

B. Option D

C. Option A

D. Option B

정답: D

문제6

In this question, you will compare the mobility processes of a network that supports WPA2Personal and WPA2-Enterprise. Assume the use of a 15-character ASCII passphrase for WPA2-Personal and EAP-TTLS/MSCHAPv2 with WPA2-Enterprise. Also, assume that proprietary roaming protocols are not supported.
When a device transitions from one BSS to another within the same ESS, what steps must be performed in the WPA2-Enterprise transition that are not performed in the WPA2Personal transition? (Choose 2)

A. Transfer of PMK from AAA server to authenticator

B. Open System Authentication

C. 802.1X authentication

D. Conversion of passphrase to PMK

E. 802.11 Reassociation

F. 4-Way Handshake

정답: A,C
