Of the following characteristics, which apply to UDP? Connection-oriented Connectionless Error checking Low overhead Best-effort delivery

A server is running HTTP, SMTP and DHCP. Which of the following best explains how the server is able to handle all three services over the same connection? The server has separate buffer areas for each application and forwards all data to each service. If the data does not apply to that application, it is discarded. The server processes each packet one at a time and forwards the data to the application that indicates that it is waiting for a transmission to arrive. The data is discarded if it does not apply to that application. The server uses the destination port number in the TCP/UDP header to identify the service. The data is forwarded to the service identified by the port number. The server uses separate three-way handshake connections to control the flow of the data and relates the service to the proper connection. This relationship allows the server to pass the data to the proper service.

When using TCP, after a session is open, the applications can adjust the amount of segments they receive before sending an acknowledgment. This behaviour is known as ______________. FCS Windowing MTU adjustment Flexible Send Path

Which address or number is used to pass the data to the correct application? MAC Number IP address Port Number Segment Number

What are the two most common transport layer protocols? UDP TCP IPX ARP

What is an advantage of UDP? Low Overhead High Overhead Reliable Not reliable

Select the most correct statement regarding client port address assignment. The client port always matches the destination port. To access a web page the client uses the source port of 80 and the destination port is dynamically selected. When a client requests a web page the destination port is 80 by default and the source port for the client is dynamically selected. The client source port is 1024 to get web pages and 1055 when retrieving ftp files.

Layer 1 and Layer 2 devices must forward a broadcast. Which of the following devices fall into this category? Gateway Switch Router All of the above.

Sutherland,

If a router uses static routing, how does it learn the route to remote networks? The router uses a RIP request to obtain remote network numbers. The router uses a routing protocol to exchange remote network numbers. The router uses DNS request packets to obtain remote network numbers. The Network Administrator manually configures the remote networks.

A big part of the overhead on a network is broadcasts. You divide a large number of hosts into smaller individual networks and separate them with the proper device According to proper networking terminology you have created separate _______________________, User Domains Broadcast Domains Collision Areas Broadcast Areas

Your PC has been configured with IP Address 192.168.3.25 and a subnet mask of 255.255.255.0. Which of the following IP Addresses is a valid default gateway address for your PC? 192.168.3.0 255.255.255.0 192.168.3.2 255.255.255.0 192.168.3.25 255.255.255.0 192.168.4.1 255.255.255.255

Which of the following are used by routers to learn routes to be added to the routing table? Ping and Traceroute MAC address resolution Acknowledgments and Sequence Numbers Routing updates and static routes

If a router uses dynamic routing, how does it learn the route to remote networks? The router uses a DHCP request to obtain remote network numbers. The router uses a routing protocol to exchange routing info. with other routers. The router uses DNS request packets to obtain remote network numbers. The Network Administrator manually configures the remote networks.

Of the following, which reason applies to dividing a large network into two or more smaller networks? Performance Security Address Management All of the above
