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

• A.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.
• B.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.
• C.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.
• D.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.

As you plan a WLAN upgrade, you have assessed the network requirements and data signatures of your applications. One of the popular applications used on your network requires high bandwidth and low to medium Wi-Fi loss, but can tolerate moderate latency and jitter.
What application matches this description?

• A.Video-on-demand
• B.Video conferencing
• C.Voice
• D.Email
• E.FTP
• F.Skype chat

Given: Use Exhibit 1, 2, and 3 to answer the question. The azimuth and elevation charts for which type of antenna are shown in Exhibit 1?

• A.Figure 5
• B.Figure 1
• C.Figure 4
• D.Figure 2
• E.Figure 3
• F.Figure 6

You are testing a VoWLAN deployment, and your communication measurements show a certain amount of lost packets. What would be an acceptable packet error rate value to still provide acceptable call quality?

• A.No more than 8% PER max should be acceptable
• B.There should be 0% error in a VoWLAN type of deployment
• C.No more than 1% PER max should be acceptable
• D.No more than 12% PER max should be acceptable
• E.No more than 4% PER max should be acceptable

During a post-deployment verification, you are requested to troubleshoot an area where users are experiencing poor throughput. They are using data communication only, mainly from laptops. You captured the frame displayed in the exhibit from the location where problems are reported. This frame is typical of those that were captured by the analyzer.

What does this frame reveal about the RF network in this area?

• A.Stations are using null data frames as protection mechanisms to reserve the medium
• B.Multipath or excessive collisions seem to be an issue in this area
• C.One station seems to be streaming video, thus may have reserved significant bandwidth via admission control
• D.The AP seems to be too far to provide enough coverage to this area
• E.Contention Free is in place in this network, which may starve some non-QoS stations from access
• F.The station that sent this frame is causing a DoS attack by using extended Duration values
