    • a dialup connection that is supplied by their local telephone service provider
    • Virtual Private Networks that would enable the company to connect easily and securely with employees
    • private dedicated lines through their local service provider
    • a broadband service, such as DSL, through their local service provider
  2. Which network scenario will require the use of a WAN?

    • Employee workstations need to obtain dynamically assigned IP addresses.
    • Employees need to connect to the corporate email server through a VPN while traveling.
    • Employees in the branch office need to share files with the headquarters office that is located in a separate building on the same campus network.
    • Employees need to access web pages that are hosted on the corporate web servers in the DMZ within their building.
  3. Which statement describes a characteristic of a WAN?

    • A WAN operates within the same geographic scope of a LAN, but has serial links.
    • WAN networks are owned by service providers.
    • All serial links are considered WAN connections.
    • A WAN provides end-user network connectivity to the campus backbone.
  4. Which two devices are needed when a digital leased line is used to provide a connection between the customer and the service provider? (Choose two.)

    • access server
    • CSU
    • Layer 2 switch
    • DSU
    • dialup modem
  5. What is a requirement of a connectionless packet-switched network?

    • Each packet has to carry only an identifier.
    • The network predetermines the route for a packet.
    • Full addressing information must be carried in each data packet.
    • A virtual circuit is created for the duration of the packet delivery.
  6. What is an advantage of packet-switched technology over circuit-switched technology?

    • Packet-switched networks are less susceptible to jitter than circuit-switched networks are.
    • Packet-switched networks can efficiently use multiple routes inside a service provider network.
    • Packet-switched networks do not require an expensive permanent connection to each endpoint.
    • Packet-switched networks usually experience lower latency than circuit-switched networks experience.
  7. What is a long distance fiber-optic media technology that supports both SONET and SDH, and assigns incoming optical signals to specific wavelengths of light?

  19. Which statement describes cable?

    • Delivering services over a cable network requires downstream frequencies in the 50 to 860 MHz range, and upstream frequencies in the 5 to 42 MHz range.
    • The cable subscriber must purchase a cable modem termination system (CMTS).
    • Each cable subscriber has dedicated upstream and downstream bandwidth.
    • Cable subscribers may expect up to 27 Mbps of bandwidth on the upload path.
  20. A new corporation needs a data network that must meet certain requirements. The network must provide a low cost connection to sales people dispersed over a large geographical area. Which two types of WAN infrastructure would meet the requirements? (Choose two.)
