A large department store is considering a VoWIP solution to be used in all 20 store locations. The plan calls for at least one employee from each department to carry a wireless handset for voice communications and a data link to a centralized inventory database for price lookup and inventory checks. Currently the company has a robust wired network in place at all of its locations including large data links between them. How should the design specialist approach the site-to-site voice trunking solution?

• A.Use the existing TDM trunking with their carrier to eliminate network congestion on the data links with the addition of IP telephones.
• B.Convince the customer to keep a wired telephone system in place at all of its locations.
• C.Recommend that the customer install additional data circuits between all of its locations to accommodate the new VoWIP traffic.
• D.Use the excess capacity of the inter-site data links for voice over IP traffic.

In the WLAN Security Switch (WSS) 2380, access points use forwarding queues to prioritize WLAN traffic. What is responsible for assigning the queue in which traffic is placed?

• A.the CoS value of the packet
• B.the DSCP value
• C.the mobility domain
• D.the IP ToS field

The WLAN 2300 series has some basic WLAN Security. There are three types of basic security offering deterrence to hackers against security. What is a basic security against hackers?

• A.WPA2
• B.Limited access area
• C.Bandwidth limitation
• D.DMZ connection

The WLAN 2300 series uses various robust security methods such as the Wi-Fi Protected Access (WPA) security method. Which statement about WPA is true?

• A.It uses 802.1x and EAP for user authentication.
• B.User authentication occurs after data encryption.
• C.Data encryption occurs after user authentication.
• D.User verification is required.

A site survey for a Wireless LAN site has been completed. Given the configuration and building materials within the facility, it is expected that a high number of access points (AP) in close proximity will be required to ensure adequate coverage. The design team is concerned with channel overlap due to the number of AP required and has determined that
802.11a will be used. Which rationale supports this choice?

• A.802.11a is better able to penetrate dense building materials than 802.11b.
• B.802.11a has more non-overlapping channels than 802.11b.
• C.802.11a uses non-overlapping channels while 802.11b does not.
• D.802.11a covers more distance than 802.11b and requires fewer APs.
