1 CCNA 4 Chapter 6 v5.0 Exam Answers 2015 (100%) 1. What are tw disadvantages f emplying telewrkers in an rganizatin? (Chse tw.) increased usage f sick r vacatin days increased difficulty f tracking task prgress slwer custmer service respnse times the need t implement a new management style increase in ffice expenses 2. Which technlgy prvides a secure cnnectin between a SOHO and the headquarters ffice? VPN QS PPPE 3. What functinality is required n ruters t prvide remte wrkers with VIP and videcnferencing capabilities? IPsec QS VPN PPPE 4. Which netwrking technlgy will ensure reliable and secure remte access when a telewrker cnnects t a crprate netwrk? an encrypted VPN tunnel ruters with QS capability a VIP and videcnferencing capable cnnectin bradband (cable r DSL) access t the crprate netwrk 5. In which layer f the TCP/IP prtcl mdel des IPsec apply security t netwrk data? applicatin transprt internet netwrk access CCNA 5 Page 1

2 6. What are tw Layer 2 WAN technlgies that can prvide secure remte cnnectins between crprate branch ffices? (Chse tw.) LTE Frame Relay leased lines QS Ipsec 7. Which tw netwrk cmpnents des a telewrker require t cnnect remtely and securely frm hme t the crprate netwrk? (Chse tw.) VPN client sftware r VPN-enabled ruter multifunctin security appliance bradband Internet cnnectin VPN server r cncentratr authenticatin server 8. Which tw OSI Layer 1 specificatins des DOCSIS define fr a cable Internet cnnectin? (Chse tw.) a deterministic media access methd channel bandwidth mdulatin technique VPN tunneling requirements the separatin f the vice and data transmissins 9. Which cable netwrk cmmunicatin technlgy is secure, extremely resistant t nise, and emplys spread-spectrum technlgy? FDMA TDMA S- 10. Which standard specifies the channel frequencies and the deterministic access methd f cable netwrks? DOCSIS LTE WiMAX What advantage des DSL have cmpared t cable technlgy? CCNA 5 Page 2

3 DSL uplad and dwnlad speeds are always the same. DSL is faster. DSL has n distance limitatins. DSL is nt a shared medium. 12. Which medium is used fr delivering data via DSL technlgy thrugh PSTN? fiber cpper radi frequency wireless 13. Hw is vice traffic affected when the custmer uses ADSL technlgy? N special equipment is needed t separate vice and data signals. Vice traffic is interrupted if the ADSL service fails. ADSL signals can distrt vice transmissins. Vice signals are n a separate wire pair frm ADSL signals. 14. Which DSL technlgy prvides higher dwnstream bandwidth t the user than upstream bandwidth? ADSL SDSL TDMA 15. Which bradband wireless technlgy is based n the standard? municipal Wi-Fi WiMAX UMTS 16. Which type f lng distance telecmmunicatin technlgy prvides pint-tpint cnnectins and cellular access? municipal Wi-Fi satellite mbile bradband CCNA 5 Page 3

4 17. A cmpany is lking fr the least expensive bradband slutin that prvides at least 10 Mb/s dwnlad speed. The cmpany is lcated 5 miles frm the nearest prvider. Which bradband slutin wuld be apprpriate? satellite DSL Cable 18. Which bradband technlgy wuld be best fr a user that needs remte access when traveling in muntains and at sea? Wi-Fi Mesh mbile bradband Satellite 19. Why is the MTU fr a PPPE DSL cnfiguratin reduced frm 1500 bytes t 1492? t enable CHAP authenticatin t reduce cngestin n the DSL link t accmmdate the PPPE headers t establish a secure tunnel with less verhead 20. What are tw characteristics f a PPPE cnfiguratin n a Cisc custmer ruter? (Chse tw.) The PPP cnfiguratin is n the dialer interface. An MTU size f 1492 bytes is cnfigured n the Ethernet interface. The Ethernet interface des nt have an IP address. The custmer ruter CHAP username and passwrd are independent f what is cnfigured n the ISP ruter. The dialer pl cmmand is applied t the Ethernet interface t link it t the dialer interface. 21. Fill in the blank. DOCSIS specifies the MAC sub-layer as a Layer 2 requirement that defines either a deterministic access methd, TDMA, r S Fill in the blank. Use nly an acrnym. CCNA 5 Page 4

5 PPPE creates a PPP tunnel thrugh the DSL cnnectin fr the purpse f sending PPP frames. 23. Match each type f bradband wireless technlgy with the crrect descriptin. (Nt all ptins are used.) CCNA 5 Page 5
