VOIP has been implemented at the main office of the Company network. Which two statements are true about voice packets in a LAN?()A、 Voice carrier stream utilizes Real-Time Transport Protocol (RTP) to carry the audio/media portion of the VoIP communication. B、 Voice traffic data flow involves large volumes of large packets.

You are the network administrator for your company. The network contains 12 Windows Server 2003 computers and 300 Windows XP Professional computers. Three servers named Server4, Server5, and Server6 run a critical business application. When performing performance baselining on these three servers, you notice that Server6 has a larger number of concurrently connected users at any given moment than Server4 or Server5. The additional workload is causing performance problems on Server6. You need to identify which client computers are connecting to Server6.You plan to run Network Monitor on Server6 to capture all packets sent to Server6. The capture task must be configured to meet the following requirements.To reduce the size of the captured data, you want to capture only the packet headers.If a large number of packets are captured, the packets must be retained on the server. Captured packets must not overwrite previously captured packets. Which two tasks should you perform to configure Network Monitor?()A、Configure the Network Monitor display filters.B、Configure the Network Monitor capture filters.C、Increase the Network Monitor buffer size setting.D、Decrease the Network Monitor buffer size setting.E、Increase the Network Monitor frame size setting.F、Decrease the Network Monitor frame size setting.
