Noted: There are 3 (25, 26, 27) concerns were updated in March, 2019.

What are two reasons for physical layer protocols to use framework encoding techniques? (Choose two.)

to minimize the number of collisions top top the mediato identify data bits from manage bitsto provide far better media error correctionto determine where the framework starts and also endsto rise the media throughput
Explanation:
An encoding an approach converts a present of data bits in a predefined password that can be well-known by both the transmitter and also the receiver. Using predefined fads helps to distinguish data bits from manage bits and also provide much better media error detection.

What is indicated by the hatchet throughput?

the guaranteed data deliver rate available by one ISPthe capacity of a particular medium to lug datathe measure of the usable data transferred throughout the mediathe measure up of the bits transferred across the media over a given duration of timethe time the takes because that a message to acquire from sender to receiver
Explanation:
Throughput is the measure of the transport of bits across the media end a given duration of time. Throughput is influenced by a variety of factors such as, EMI and latency, so it seldom matches the mentioned bandwidth for a network medium. The throughput measurement consists of user data bits and also other data bits, such as overhead, acknowledging, and also encapsulation. The measure up of the usable data transferred across the media is referred to as goodput.

A network administrator notices that part newly installed Ethernet cabling is transporting corrupt and distorted data signals. The new cabling was set up in the ceiling close come fluorescent lights and electrical equipment. I m sorry two factors may interfere v the copper cabling and result in signal distortion and data corruption? (Choose two.)

EMIcrosstalkRFIsignal attenuationextended length of cabling
Explanation:
EMI and also RFI signals have the right to distort and corrupt data signals that are brought by copper media. These distortions typically come indigenous radio waves and electromagnetic gadgets such together motors and florescent lights. Crosstalk is a disturbance the is resulted in by adjacent wires bundled also close together with the magnetic ar of one wire affecting another. Signal attenuation is led to when an electrical signal starts to deteriorate over the length of a copper cable.

Which characteristic explains crosstalk?

the distortion that the network signal indigenous fluorescent lightingthe distortion that the sent messages from signals lugged in adjacent wiresthe weakening of the network signal over lengthy cable lengthsthe ns of wireless signal over extreme distance native the accessibility point
Explanation:
EMI and RFI have the right to distort network signals because of interference native fluorescent lamp or electric motors. Attenuation results in degradation of the network signal together it travels along copper cabling. Wireless gadgets can endure loss of signals due to the fact that of excessive distances from a accessibility point, but this is no crosstalk. Crosstalk is the disturbance caused by the electric or magnetic fields of the signal brought on an nearby wire in ~ the exact same cable.

What an approach is provided with UTP cable to assist protect against signal interference native crosstalk?

twisting the wires together right into pairswrapping a foil shield approximately the wire pairsencasing the cables within a flexible plastic sheathterminating the cable through special grounded connectors
Explanation:
To help prevent the effects of crosstalk, UTP cable wires room twisted together right into pairs. Twisting the wires together reasons the magnetic areas of each wire to publication each other out.

Refer come the exhibit. The pc is connected to the console port of the switch. Every the various other connections are made through FastEthernet links. Which varieties of UTP cables have the right to be used to affix the devices?

Cisco ITN CCNA 1 v6.0 thing 4 test Answer R&S 2018 2019 003


All 3 networks usage CSMA/CANone of the networks call for media access control.Network 1 uses CSMA/CD and Network 3 provides CSMA/CA.Network 1 provides CSMA/CA and also Network 2 uses CSMA/CD.Network 2 provides CSMA/CA and also Network 3 offers CSMA/CD.

What is consisted of in the trailer of a data-link frame?

logical addressphysical addressdataerror detection
Explanation:
The trailer in a data-link frame has error detection information that is pertinent to the frame had in the FCS field. The header contains control information, such as the addressing, when the area the is suggested by the word “data” contains the data, transport layer PDU, and the IP header.

As data travels on the media in a present of 1s and 0s just how does a receiving node determine the beginning and also end the a frame?

The transmitting node inserts start and stop bits right into the frame.The transmitting node sends out a beacon to inform that a data frame is attached.The receiving node identifies the beginning of a frame by seeing a physical address.The transmitting node sends an out-of-band signal come the receiver around the beginning of the frame.
Explanation:
When data travels on the media, the is converted into a present of 1s and 0s. The framing process inserts right into the framework start and stop indicator flags so the the location can recognize the beginning and end the the frame.

What is the role of the CRC value that is found in the FCS field of a frame?

to verify the integrity of the got frameto verify the physical attend to in the frameto verify the logical deal with in the frameto compute the checksum header for the data field in the frame
Explanation:
The CRC worth in the FCS field of the received frame is compared to the computed CRC value of that frame, in order to verify the integrity of the frame. If the 2 values execute not match, climate the frame is discarded.

Fill in the blank.

The term bandwidth shows the capacity of a medium to carry data and it is generally measured in kilobits per second (kb/s) or megabits per second (Mb/s).

Fill in the blank.

What acronym is provided to referral the data link sublayer the identifies the network class protocol encapsulated in the frame? LLC

Fill in the blank.

A physical topology the is a sport or combination of a point-to-point, hub and spoke, or mesh topology is commonly known together a hybrid topology.

Match the features to the correct kind of fiber. (Not all alternatives are used.)

What is the definition of bandwidth?

the measure of the carry of bits across the media end a given period of timethe speed at i m sorry bits take trip on the networkthe lot of data that can flow from one place to one more in a offered amount that timethe measure up of usable data moved over a given period of time
Explanation:
Bandwidth is the measure up of the volume of a network tool to bring data. It is the quantity of data that deserve to move between two point out on the network end a specific duration of time, frequently one second.

What is a duty of the Logical link Control sublayer?

to provide access to miscellaneous Layer 1 network technologiesto administer data connect layer addressingto specify the media access processes performed by network hardwareto note frames to identify the network class protocol being carried
Explanation:
There are two data connect sublayers, MAC and LLC. The llc sublayer is responsible for communicating with the network layer and also for tagging frames to determine what great 3 protocol is encapsulated.

What space two instances of hybrid topologies? (Choose two.)

partial meshextended starhub and spokepoint-to-pointfull mesh
Explanation:
A hybrid topology is one the is a sport or a combination of various other topologies. Both partial mesh and the expanded star are examples of hybrid topologies.
