LTE Frame Relay leased lines QoS IPsec.Which two OSI Layer 1 specifications does DOCSIS define for a cable Internet connection? (Choose two.) a deterministic media access method channel bandwidth modulation technique VPN tunneling requirements the separation of the voice and data transmissions.Which medium is used for delivering data via DSL technology through PSTN? fiber copper radifrequency wireless.A company is looking for the least expensive broadband solution that provides at least 10 Mb/s download speed. The company is located 5 miles from the nearest provider. Which broadband solution would be appropriate? satellite DSL WiMax cable.Fill in the blank.DOCSIS specifies the ___ sub-layer as a Layer 2 requirement that defines either a deterministic access method, TDMA, or S-CDMA.Fill in the blank. Use only an acronym._____ creates a PPP tunnel through the DSL connection for the purpose of sending PPP frames..Which broadband wireless technology is based on the 802.11 standard? CDMA municipal Wi-Fi UMTS WiMAX.Why is the MTU for a PPPoE DSL configuration reduced from 1500 bytes t1492? to enable CHAP authentication to accommodate the PPPoE headers to reduce congestion on the DSL link to establish a secure tunnel with less overhead.Which standard specifies the channel frequencies and the deterministic access method of cable networks? DOCSIS 802.16 LTE WIMAX.Which two network components does a teleworker require to connect remotely and securely from home to the corporate network? (Choose two.) VPN client software or VPN-enabled router broadband Internet connection VPN server or concentrator authentication server multifunction security appliance.In which layer of the TCP/IP protocol model does IPsec apply security to network data? application transport internet network access.Which cable network communication technology is secure, extremely resistant to noise, and employs spread-spectrum technology? CDMA S-CDMA FDMA TDMA.How is voice traffic affected when the customer uses ADSL technology? No special equipment is needed to separate voice and data signals. Voice traffic is interrupted if the ADSL service fails. Voice signals are on a separate wire pair from ADSL signals. ADSL signals can distortvoice transmissions..Which technology provides a secure connection between a SOHO and the headquarters office? PPPoE QoS WiMax VPN.What are two characteristics of a PPPoE configuration on a Cisco customer router? (Choose two.) The customer router CHAP username and password are independent of what is configured on the ISP router. The PPP configuration is on the dialer interface. An MTU size of 1492 bytes is configured on the Ethernet interface. The Ethernet interface does not have an IP address. The dialer pool command is applied to the Ethernet interface to link it to the dialer interface..What advantage does DSL have compared to cable technology? DSL upload and download speeds are always the same. DSL is not a shared medium. DSL is faster. DSL has no distance limitations..What are two disadvantages of employing teleworkers in an organization? (Choose two.) slower customer service response times increased usage of sick or vacation days increased difficulty of tracking task progress increase in office expenses the need to implement a new management style.Match each type of broadband wireless technology with the correct description. (Not all options are used.) WiMax satellite cellular/mobile.Which DSL technology provides higher downstream bandwidth to the user than upstream bandwidth? SDSL TDMA CDMA ADSL.Which networking technology will ensure reliable and secure remote access when a teleworker connects to a corporate network? an encrypted VPN tunnel routers with QoS capability broadband (cable or DSL) access to the corporate network a VoIP and videoconferencing capable connection.Which broadband technology would be best for a user that needs remote access when traveling in mountains and at sea? satellite Wi-Fi Mesh mobile broadband WiMax.Which type of long distance telecommunication technology provides point-to-point connections and cellular access? WiMax satellite mobile broadband municipal Wi-Fi.What functionality is required on routers to provide remote workers with VoIP and videoconferencing capabilities? QoS VPN PPPoE IPsec.What are two features of wavelengths in the electromagnetic spectrum? (Choose two.) They are the rate at which current or voltage cycles occur. They are calculated by the speed of propagation of the electromagnetic signal divided by its frequency in cycles per second. They are the distance from the peak of one radio wave to the peak of the next radio wave. They are the distance from the peak of one radio wave to the trough of the next radio wave. They are calculated by the number of waves per second..When PPPoE is configured on a customer router, which two commands must have the same value for the configuration to work? (Choose two.) ppp chap hostname 2 pppoe-client dial-pool-number 2 ppp chap password 2 interface dialer 2 dialer pool 2 interface gigabitethernet 0/2.What mobile broadband communication Layer 2 technology uses a special coding scheme to assign each transmitter a specific code? UMTS TDMA FDMA CDMA.What technology provides service providers the capability to use authentication, accounting, and link management features to customers over Ethernet networks? QoS PPPoE ISDN DSL.What two layers of the OSI model are defined by DOCSIS? (Choose two.) layer 1 layer 2 layer 3 layer 4 layer 5 layer 6 layer 7.
