After surveying for the ideal mounting locations for APs, you have been asked to compromise RF propagation optimization due to aesthetic concerns raised by your customer. In the end, you've decided to mount the APs in the ideal locations and paint the APs so they go unnoticed in the environment.
What is a valid recommendation or consideration when painting APs? (Choose 2)

A. Most AP models for indoor environments come in a variety of form factors and colors. Painting is never recommended.

B. Always use paints with metallic dye in them to prevent potential RF propagation impact.

C. Painting APs always introduces a fire and gas emissions hazard and should be avoided for all indoor APs.

D. Do not paint the notification LEDs on the AP, but configure them to be dim or turned off altogether until troubleshooting is required.

E. Painting APs may void the product manufacturer's warranty.

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

A. 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.

B. 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.

C. 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.

D. 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.

What statement is true of a WLAN design that supports Real-Time Location Services (RTLS) with 802.11 RFID asset tags? (Choose 2)

A. When tracking assets with passive RFID tags, some APs should be moved, or additional APs be added, to provide more accurate triangulation and location services.

B. With passive tags, AP transmit gain should be increased to supply extra power for near-field coupling or backscatter modulation from the tag to the AP since the passive tag lacks an internal power source.

C. When passive tags are implemented, the AP density should be increased by 25% to make up for the shorter transmit range of passive tags as compared to active tags.

D. Active tags transmit directly to the APs and may not require 802.11 authentication and association to pass data traffic to the RTLS engine.

E. Active RFID tags periodically transmit 802.11 beacon management frames that must be synchronized with the AP for proper location of the tagged asset.

F. Passive tags do not communicate directly with the WLAN infrastructure, but instead they rely on the tag interrogator to communicate tag information to the infrastructure's location tracking server/database.

You are working on a VoWLAN design with your customer's wired networking team. How many distinct priority levels do you expect for the voice applications?

A. 1 priority level per client and AP pair, so the total number depends on the expected number of clients

B. 1 priority level for voice RTP, 1 priority level for voice control and RTCP

C. 1 priority level for VoWLAN client traffic, 1 priority level for wired VoIP client traffic

D. 1 priority level, but 2 queues (one for uplink traffic, one for downlink traffic)
