50 Dense Wave Division Multiplexing (DWDM) is a signaling technology that has become a popular choice in the construction of which of the following types of provider links?Digital Subscriber Line (DSL)Metro-opticalSatelliteCable

51 Which of the following statements is true about the differences between a peer-to-peer network and a client-server network?Peer-to-peer networks are inherently less secure than client-server networks.Peer-to-peer networks are illegal, while client-server networks are legal.On peer-to-peer networks, every workstation is capable of authenticating users.On a peer-to-peer network, all workstations must share their resources.

52 Why does DSL (Digital Subscriber Line) technology support faster data transmissions than a standard Public Switched Telephone Network (PSTN) modem connection?DSL uses a separate control circuit that provides clear channels for data.DSL does not perform Cyclic Redundancy Check (CRC) functions and therefore has less overhead.DSL performs only a single analog-to-digital conversion.DSL uses a higher frequency range.

53 Which DSL (Digital Subscriber Line) technology can adjust its transmission speed based on line conditions?HDSLIDSLRADSLVDSL

54 Which of the following Wide Area Network (WAN) technologies uses broadband signaling?Digital Subscriber Line (DSL)Synchronous Optical Network (SONET)Integrated Services Digital Network (ISDN)Cable television (CATV)

55 Ed has been hired by a private company to connect two remote sites with a Wide Area Network (WAN). Each of these sites has more than 200 users, and they all need to constantly transfer files across the WAN. One of the sites has a customer database that is accessed by both sites at all hours of the day. Access to the database and other information is time sensitive and constant. The company estimates that their aggregate bandwidth needs to be approximately 40 Mbps. Management says that they need to guarantee access to this information and that money is not a factor in the WAN implementation. Which WAN technology should Ed recommend for this scenario?A standard modem-to-modem connectionA T-3 dedicated leased lineA cable television (CATV) connectionAn ADSL (Asymmetrical Digital Subscriber Line) connection

56 Ralph is an employee of a company that offers the option to telecommute from home. As a telecommuting employee, he needs to connect to the company network to access client information, transfer files, and send email through a Virtual Private Network (VPN) connection. Ralph is investigating the different Wide Area Network (WAN) services available for the remote connection before he implements one. His home is over 30 years old; the existing telephone wiring was not run through conduit, and the wiring seems to be deteriorating. Ralph has cable television (CATV) service, and his home is also approximately 20,000 feet from the nearest telephone central office. He wants to implement the fastest remote connection service possible, but cost is a factor in the decision. Which WAN technology should Ralph implement?A dedicated leased line (fractional T-1)A standard modem-to-modem connectionA DSL (Digital Subscriber Line) connectionA broadband CATV connection

57 Which of the following Wide Area Network (WAN) connection technologies uses analog signaling?Public Switched Telephone Network (PSTN)Cable television (CATV)Digital Subscriber Line (DSL)Synchronous Optical Network (SONET)

58 If you want to allow both voice and data traffic to be transmitted across the same Digital Subscriber Line (DSL) connection, what type of device is required at the customer site?A signal terminatorA Digital Subscriber Line Access Multiplexer (DSLAM)A coder/decoder (CODEC) deviceA splitter

59 What are the two main factors that affect DSL (Digital Subscriber Line) transmission rates?Signal terminationDistance to the nearest central officeLine conditionsLine reflection

60 Which of the following best describes the function of a demarcation point or demarc?The vertical cross-connect that links horizontal networks togetherThe place where an outside service enters the buildingA switch or hub that connects the computers in a particular work area together, forming a horizontal networkThe place in a telecommunications room where a patch panel is located

61 Which of the following broadband WAN services provides equal amounts of upstream and downstream bandwidth?ADSLSDSLSatelliteCable
