    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.
