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. C、 Because a packet loss involves a small amount of data, voice traffic is less affected by packet losses than traditional data traffic is. D、 Voice packets are encapsulated in TCP segments to allow for proper sequencing during delivery. E、 Voice packets are very sensitive to delay and jitter.
An expanding company is deploying leased lines between its main site and two remote sites. The bandwidth of the leased lines is 128kb/s each， terminated on different serial interfaces on the main router. These links are used for combined VOIP and data traffic. The network administrator has implemented a VOIP solution to reduce costs， and has therefore reserved sufficient bandwidth in a low latency queue on each interface for the VOIP traffic. Users now complain about bad voice quality although no drops are observed in the low latency queue.What action will likely fix this problem？（）A、mark VOIP traffic with IP precedence 6 and configure only ’fair-queue’ on the linksB、configure the scheduler allocate 3000 1000 command to allow the QoS code to have enough CPU cyclesC、enable class-based traffic shaping on the VoIP traffic classD、enable Layer 2 fragmentation and interleaving on the linksE、enable Frame Relay on the links and send voice and data on different Frame Relay PVCs
While using a packet analyzer， you notice four additional bytes being added to the packets in the Company network. Which protocol inserts a four byte tag into the Ethernet frame and recalculates CRC value？ （）A、 DTPB、 VTPC、 802.1QD、 ISLE、 None of the other alternatives apply
You need to configure a new Cisco router to be installed in the Company VOIP network.
