A host is transmitting a video over the network. How does the transport layer allowthis host to use multiple applications to transmit other data at the same time as the videotransmission?- It uses error control mechanisms.- It uses a connectionless protocol only for multiple simultaneous transmissions.- It uses multiple Layer 2 source addresses.- It uses multiple port numbers.13. Refer to the exhibit. PC1 is unable to access PC2. To troubleshoot this problem, thetechnician needs to confirm that the next hop interface is operational.
Which defaultgateway address should the technician ping from PC1 to confirm this?- 10.0.0.254- 192.168.0.249- 192.168.0.250- 10.0.1.25414. Refer to the exhibit.

Refer to the exhibit. Which two facts can be determined about the topology? (Choosetwo.)- Three networks are needed.- Two logical address ranges are required.- A single broadcast domain is present.- Three collision domains are present.- Four networks are needed.16.
Refer to the exhibit. Which three statements are true about the IP configuration that isdisplayed? (Choose three.)- The assigned address is a private address.- The PC cannot communicate with the DNS server.- The network can have 126 hosts.- The prefix of the computer address is /26.- The IP address is routable on the Internet.- The IP address is a multicast address.CCNA Exploration v.4.0http://ccna-examinations.blogspot.com17.
Which password restricts Telnet access to the router?- enable- enable secret- console- VTY18. Refer to the exhibit. To create the initial configuration, a network technicianconnected host A to the router using the connection that is shown. Which statement istrue about this connection?- It terminates at the Ethernet port of the router.- It provides out-of-band console access.- It terminates at the serial interface of the router.- It requires a Telnet client on host A to access the router.19.

Refer to the exhibit. In a network, host A is sending data segments to host B.

Тип файла PDF
PDF-формат наиболее широко используется для просмотра любого типа файлов на любом устройстве. В него можно сохранить документ, таблицы, презентацию, текст, чертежи, вычисления, графики и всё остальное, что можно показать на экране любого устройства. Именно его лучше всего использовать для печати.
Например, если Вам нужно распечатать чертёж из автокада, Вы сохраните чертёж на флешку, но будет ли автокад в пункте печати? А если будет, то нужная версия с нужными библиотеками? Именно для этого и нужен формат PDF - в нём точно будет показано верно вне зависимости от того, в какой программе создали PDF-файл и есть ли нужная программа для его просмотра.
