what is true concerning physical and logical topologies

1. Exhibition reference. What is wrong with the displayed termination?Read: what is true regarding the physical and logical topology The conductors are too thick for the connector used. The untwisted length of each wire is too long. Woven copper braids should not be removed. Using the wrong connector type. Read more: Who is the kurt in if2. Why are two optical fibers used for one fiber optic connection? They prevent crosstalk from interfering with the connection. They speed up data transfer. Two fibers allow data to travel over longer distances without degradation. They allow duplex connections. Read more: Who is the kurt in what if3. Reference to the exhibition. Which sentence describes the media access control methods used by networks in the show? All three networks use CSMA/CA Network 1 uses CSMA/CD and Network 3 uses CSMA/CA. Network 1 uses CSMA/CA and Network 2 uses CSMA/CD. Network 2 uses CSMA/CA and Network 3 uses CSMA/CD. No network requires media access control. Read more: Who is the kurt in what if4.

What is an advantage of using fiber optic cable instead of copper cable? It can be installed around sharp bends. It is usually cheaper than copper cable. It can transmit signal much farther than copper cable. It is easier to terminate and install than copper cables. Read more: Who is the kurt in what if7. Match the features with the right yarn.

What are the two services performed by the data link layer of the OSI model? (Choose two.) It accepts Layer 3 packets and encapsulates them into frames. It defines the path to forward the packet. It encrypts data packets. It oversees Layer 2 communication by building a table of MAC addresses. It provides media access control and performs error detection.

What three areas of concern need to be taken into account when building a wireless network? (Choose three). the measure of usable data transmitted over the medium the measure of the bits transmitted over the medium in a given amount of time the time it takes for a message to get from the sender to the capable receiver of a particular medium to carry data the data is guaranteed to be the transfer rate provided by ISPR Read more: Who is the kurt in what if14. What is the function of the CRC value found in the frame’s FCS field? To calculate checksum header for data field in frame to verify logical address in frame to verify physical address in frame to verify received frame integrity Read more: Who is kurt in what what if15. What technique is used with UTP cables to help protect against signal interference due to crosstalk? wrap a foil shield around wire pairs twist the wires together into pairs of cable terminals with special grounding connectors that wrap the cable in a flexible plastic sheath Read more: Who knows if16. Which feature describes crosstalk? distortion of messages transmitted from signals carried in adjacent wires, loss of wireless signals over long distances from the access point, attenuation of network signals over long cable lengths, distortion of network signal from fluorescent light Read more: Who gets sick what if17. As data moves across the medium in the stream of 1s and 0s how does a receiving node determine the beginning and end of the frame? The transmitting node inserts the start and stop bits into the frame. The receiving node identifies the beginning of the frame by seeing a physical address. The transmitting node sends a beacon to notify that a data frame is attached. The transmitting node sends an out-of-band signal to the receiver about the start of the frame.

New cabling is installed on the ceiling close to the fluorescent lights and electrical equipment. What two factors can interfere with copper cabling and lead to signal distortion and data corruption? (Choose two.) Extended length of RFI cable signal loss EMI crosstalk Read more: Who is unknown in what if19. What is true regarding the physical and logical topology? The physical topology is concerned with the way frames are transmitted. The physical topology shows the IP address scheme of each network. Logical topology is always the same as physical topology. Logical topology refers to the way data is transferred between devices. Read more: Who is the kurt in what if20. Which statement describes the extended star topology? The terminals are connected to each other by a bus, and each bus connects to a central intermediate device. All terminals and intermediate devices are connected in a chain to each other. The terminals connect to a central intermediate, which in turn connects to other central intermediates. Each end system is connected to its respective neighbor through an intermediate device.
