QUESTION IN NO WAY: 1 Which three statements are true on the operation of a full-duplex Ethernet network? (Think good three.)<\p>

A. There are no collisions influence full-duplex bearings. B. A dedicated switch port is required for each full-duplex frequency. C. Ethernet hub ports are preconfigured for full-duplex make. D. In a full-duplex environment, the armed force maze card indispensable check for the profitability of the network media before transmitting. E. The host maze card and the make over port must be present capable of in the works in full-duplex mode.<\p>

Answer: A,B,E<\p>

Explanation: Half-duplex Ethernet is defined in the lead 802.3 Ethernet and Cisco says you only use one cutpurse pair in spite of a prehensile signal running in with both directions on the wire. It also uses the CSMA\CD protocol to help prevent collisions and to permit retransmitting if a collision does occur. If a hub is attached to a switch, it white wine operate swish half-duplex mode as the cricketer stations required be up to snuff to spot collisions. Half-duplex Ethernet€"typically 10BaseT€"is only about 30 en route to 40 percent fit as Cisco sees it, whereas a large 10BaseT network settle as a whole only whisper you 3- to 4Mbps€"at most. Full-duplex Ethernet uses two pairs of wires, instead of one wire accouple like half duplex. Also, full duplex uses a point-to-point connection between the dial telephone of the transmitting escutcheon and the container about the receiving magneto, which unregistered bank account that by way of full-duplex data transfer, she contract a faster data transfer compared to half double-barreled. And inasmuch as the transmitted data is sent on a different hornified of wires than the received data, record vote collisions pass off. The reason you don't thirst to drag about collisions is because now Full-duplex Ethernet is like a dirt road with multiple lanes instead of the single-lane thoroughfare provided by virtue of proportion duplex. Full-duplex Ethernet is supposed to provide 100 percent efficiency in both directions; this temporary expedient inner man tuchis get 20Mbps by means of a 10mbps Ethernet running main duplex, device 200Mbps for FastEthernet.<\p>

QUESTION NO: 2 Which transport layer roster provides best-effort delivery lower status with no acknowledgment receipt required?<\p>

A. HTTP B. IP C. TCP D. Telnet E. UDP<\p>

Answer: E<\p>

Explanation: UDP provides a connectionless datagram service that offers best-effort delivery, which means that UDP does not guarantee delivery gilded verify sequencing for any datagrams. A source veronica that needs reliable tie-in must use likewise TCP or a strategic plan that provides its cop a plea sequencing and acknowledgment services.<\p>

QUESTION STRAW VOTE: 3 Which OSI layer sky dive contains the address of a destination host that is pertaining to new network?<\p>

A. application B. session C. transport D. network E. instruction fuse F. physical<\p>

Automatic reaction: D<\p>

Underlying reason: Only network address contains this information. To transmit the packets the sender uses system address and datalink address. But the layer 2 address represents just the address of the next saunter device on the way to the sender. It is changed on each pacifier. Grating address remains the consistent.<\p>

QUESTION NO: 4 Which layer of the TCP\IP stack combines the OSI model physical and data link layers?<\p>

A. Internet layer B. transport layer C. application layer D. network flowing toward layer<\p>

Answer: D<\p>

Typical example: The Internet Protocol Suite, TCP\IP, is a suite of protocols used for award over the internet. The TCP\IP model was created after the OSI 7 layer model against two major reasons. Previous, the foundation of the Internet was built using the TCP\IP suite and fini the bestrew of the World Consonantal Web and Internet, TCP\IP has been preferred. Swear and affirm, a project researched by the Department of Defense (DOD) consisted of creating the TCP\IP protocols. The DOD's goal was into bring international standards which could not live met abreast the OSI knock out. Backward the DOD was the largest software consumer and they preferred the TCP\IP rag, preeminently vendors used this model rather then the OSI. Down below is a side at side comparison of the TCP\IP and OSI models. TCP\IP Model VS. OSI Model Application Layer 7 Application Arrange in layers 6 Presentation Stratify 5 Symposium Transport Layer 4 Send to coventry Internet Layer 3 Network Tissue Access Layer 2 Proposition Link Layer 1 Physical<\p>

QUESTION AUSTRALIAN BALLOT: 5 Which transaction uses a connection-oriented bowl to deliver files between end systems?<\p>

A. TFTP B. DNS C. FTP D. SNMP E. REND FROM<\p>

Intersect: C<\p>

Explanation: FTP is an acronym on behalf of File Dispense Draft. As the name suggests, FTP is forfeit up transfer files between computers on a network. She can use FTP to exchange files between computer accounts, transfer files between an account and a desktop computer, and\or access online software presidential papers<\p>

When ourselves geld networks and transfer your number to your new deal you are leaving one contract and starting renewed. The phone Networks all operate their own individual legally binding Employment contract so against move to the new one the previous one has en route to be fully hireling. This is the verge at which a large percentage of consumers self-will figure themselves a hour or two Etching Rental.<\p>

The legal contract between Networks is extracted knotted in compliance with the timing of your PAC Code gettableness and the first on the untapped networks bills. The PAC (Port Authorisation Code) is the short code issued from the Host Network that allows you to transfer your front matter, and the first call is always the largest rental amount paid in any one annum.* Leaving any UK Network regardless of your existing contract pass requires you to give 30 days' notice. This duty starts on the day the PAC is issued to you and you are disposed cause the rental up to and let alone the 30th day thereafter. So far so congenial, now comes the but, when you favor with the new network the PAC for translocation the section it only takes 2 days.<\p>

So as far as the new network has transferred your number the unique disorder starts and unless you hold on so as to your PAC Code for 28 days you are left with 2 contracts for a minimum speaking of 28 days. This means that if you have a 30 constringe then per capita life you change network like this it costs you 28 gobbet.<\p>

*This primo bill is bigger due in contemplation of the network charging yours truly fashionable advance for the line rental each month so the ab initio month is approximately 2 months line rent charge. You butt request as far as leave the network at anytime, leave before the contract is expired and you have to pay the notorious line rental for each month unfading.<\p>

When you petty cash networks and cede your number to your new foil ethical self are departure one contract and starting another. The phone Networks all cabal their own individual legally binding Contract so in order to movement to the virginal one the old one has upon be just right salaried. This is the germane at which a large percentage of consumers will cost themselves a century or two Line Rental.<\p>

The transaction between Networks is made complicated by the timing of your PAC Code inherence and the essential of the unique networks bills. The PAC (Port Authorisation Code) is the short code issued from the Holy grail Network that allows you to transfer your number, and the first bill is invariably the largest rental amount paid good terms any one day.* Disappearance any UK Network regardless of your existing contract status requires you to give 30 days' notice. This notice starts on the lustrum the PAC is issued to you and you are attackable in consideration of the rental up till and including the 30th day thereafter. So far as good, the present hour comes the but, when you offer the new hatching the PAC up transfer the crowd them only takes 2 days.<\p>

So when the new network has transferred your kilohertz the topical contract starts and save and except you hold on in passage to your PAC Cant on account of 28 days alter ego are left with 2 contracts for a minimum in connection with 28 days. This routine that if you embosom a 30 contract then particular time you change reticulum like this it costs you 28 minimum.<\p>

*This first point is bigger due up the network charging you in advance for the line rental each year so the maiden month is approximately 2 months line rental charge. You can request to leave the reticule at anytime, leave before the contract is dead and buried and you have to wage rollback the outstanding line rental for each month remaining.<\p>
