    الاسئله هي

    1-
    Two peer hosts are running applications that exchange data using UDP. During the current session, a datagram fails to arrive at the destination. What is true concerning the retransmission of the datagram?

    *Datagram retransmission occurs when the retransmission timer expires in the source host.

    Datagram retransmission occurs when the retransmission timer expires in the destination host.

    Datagram retransmission is controlled by the application layer protocol.

    Datagram retransmission involves only the data with sequence numbers equal to or higher than the sequence number of the current datagram.

    2-

    SMTP

    HTTP

    TFTP

    3-
    Which of the following commands could be used on a Windows-based computer to view the current IP configuration of the system? (Choose two.)

    4-
    Which of the following describe the token-passing logical topology? (Choose two.)

    هنالك نقطتين اضافيه نسيتها من السؤال الاخير رقم 21 وهي
    The switch compares 192.168.10.11 to the addresses in the routing table to make the forwarding decision.
    To make the forwarding decision, the switch looks in its switch table for address aaaa.bbbb.cccc. 

    شكرا جزيلا بأنتظار اجاباتكم بسرعهههههههههههههههههههههه ارجوكم محتاجه الاسئله كثيرا
    مع السلامه وفقكم الله جميعا

    *Datagram retransmission occurs when the retransmission timer expires in the source host.

    Datagram retransmission occurs when the retransmission timer expires in the destination host.

    هذا هو الجواب وذلك لأن الUDP هو عبارة عن best effort ولا يهتم اذا وصلت المعلومات ام لم تصل فهو يبعث المعلومات ولا يبحث في وصولها من عدمه وذلك لانه لا يستخدم ACK
