What Are Two Reasons For Physical Layer Protocols To Use Frame Encoding Techniques?
From year to year, Cisco has actually updated countless versions with difference questions. The latest variation is version 6.0 in 2018. What is your version? It counts on your instructor creating your class. Us recommend you to go assumed all variation if you room not clear. While girlfriend take online test through netacad.com, girlfriend may get random concerns from all version. Every version have actually 1 to 10 various questions or more. After you evaluation all questions, You should practice v our online test mechanism by go to "Online Test" connect below.
18.104.22.168 Packet Tracer – Connecting a Wired and also Wireless LAN
What room two factors for physics layer protocols come use frame encoding techniques? (Choose two.)
to alleviate the variety of collisions on the mediato identify data bits from control bitsto provide much better media error correctionto recognize where the framework starts and endsto rise the media throughput
Explanation: An encoding an approach converts a currently of data bits in a predefined password that have the right to be recognized by both the transmitter and also the receiver. Making use of predefined patterns helps to distinguish data bits from control bits and also provide much better media error detection.
What is suggested by the term throughput?
the guarantee data move rate available by an ISPthe capacity of a details medium to bring datathe measure of the usable data transferred across the mediathe measure up of the bits transferred across the media end a given duration of timethe time that takes for a blog post to acquire from sender to receiver
Explanation: Throughput is the measure up of the move of bits throughout the media end a given duration of time. Throughput is affected by a number of factors such as, EMI and also latency, therefore it hardly ever matches the stated bandwidth for a network medium. The throughput measurement includes user data bits and also other data bits, such together overhead, acknowledging, and encapsulation. The measure up of the usable data transferred throughout the media is called goodput.
A network administrator notices that part newly mounted Ethernet cabling is carrying corrupt and also distorted data signals. The new cabling was set up in the ceiling close to fluorescent lights and electrical equipment. I m sorry two components may interfere through the copper cabling and an outcome in signal distortion and data corruption? (Choose two.)
EMIcrosstalkRFIsignal attenuationextended size of cabling
Explanation: EMI and RFI signals deserve to distort and corrupt data signals the are carried by copper media. These distortions normally come from radio waves and also electromagnetic tools such together motors and also florescent lights. Crosstalk is a disturbance the is caused by nearby wires bundled as well close together with the magnetic field of one cable affecting another. Signal attenuation is resulted in when an electrical signal starts to damage over the size of a copper cable.
Which characteristic describes crosstalk?
the distortion of the network signal indigenous fluorescent lightingthe distortion that the transmitted messages from signals lugged in adjacent wiresthe weakening the the network signal over long cable lengthsthe lose of wireless signal over too much distance indigenous the accessibility point
Explanation: EMI and also RFI can distort network signals because of interference from fluorescent lights or electric motors. Attenuation outcomes in destruction of the network signal together it travels follow me copper cabling. Wireless devices can suffer loss of signals because of excessive distances from a access point, yet this is not crosstalk. Crosstalk is the disturbance brought about by the electrical or magnetic areas of the signal carried on an surrounding wire within the exact same cable.
What method is used with UTP cable to assist protect against signal interference from crosstalk?
twisting the wires together into pairswrapping a silver paper shield roughly the wire pairsencasing the cables in ~ a flexible plastic sheathterminating the cable with special grounded connectors
Explanation: To help prevent the effects of crosstalk, UTP cable wires room twisted together right into pairs. Twisting the wires together causes the magnetic fields of each cable to cancel each other out.
Refer come the exhibit. The computer is connected to the console port of the switch. All the other connections room made v FastEthernet links. Which varieties of UTP cables have the right to be offered to affix the devices?
CCNA1 thing 4 v5.1 001
All 3 networks usage CSMA/CANone of the networks require media accessibility control.Network 1 uses CSMA/CD and also Network 3 provides CSMA/CA.Network 1 provides CSMA/CA and Network 2 supplies CSMA/CD.Network 2 offers CSMA/CA and Network 3 provides CSMA/CD.
What is included in the trailer of a data-link frame?
Explanation: The trailer in a data-link frame contains error detection info that is pertinent come the frame contained in the FCS field. The header has control information, such together the addressing, while the area that is shown by the word “data” consists of the data, move layer PDU, and also the IP header.
As data travel on the media in a present of 1s and 0s exactly how does a receiving node determine the beginning and end that a frame?
The transmitting node inserts start and also stop bits right into the frame.The transmitting node sends a beacon to educate that a data frame is attached.The receiving node identify the beginning of a structure by see a physical address.The transmitting node sends an out-of-band signal come the receiver around the start of the frame.
Explanation: When data travel on the media, it is converted into a present of 1s and 0s. The framing process inserts right into the structure start and also stop indicator flags so the the destination can detect the beginning and end of the frame.
What is the function of the CRC value that is uncovered in the FCS ar of a frame?
to verify the integrity of the received frameto verify the physical deal with in the frameto verify the logical resolve in the frameto compute the checksum header for the data field in the frame
Explanation: The CRC value in the FCS ar of the received frame is compared to the computed CRC worth of the frame, in order come verify the integrity of the frame. If the two values execute not match, climate the structure is discarded.
Fill in the blank.
The hatchet bandwidth suggests the capacity of a tool to carry data and it is commonly measured in kilobits per second (kb/s) or megabits per 2nd (Mb/s).
What acronym is supplied to recommendation the data link sublayer the identifies the network class protocol encapsulated in the frame? LLC
Match the qualities to the correct form of fiber. (Not all choices are used.)
