Certmaster Comparing WAN Links and Remote Access Methods Flashcards
A network engineer is assigned to locate and acquire information from their ISP to set up network connectivity. What type of network is the engineer setting up to gain internet access?
A.WAN
B.T-Carrier
C.Enterprise WAN
D.Digital Subscriber Line
C
The term enterprise WAN describes a WAN operated and controlled by a single organization.
Wide area network (WAN) technologies support data communications over greater distances than LANs. Long-distance communications usually involve the use of public networks. Public networks are owned by telecommunications (telco) companies and provide WAN services to businesses and households.
The T-carrier system was developed by the telecommunications provider Bell Labs. This system allows a user to place multiple calls on a single cable.
Digital subscriber line (DSL) is a technology for transferring data over voice-grade telephone lines, often referred to as the local loop.
A network technician is assigned to find the fastest solution, regarding bandwidth capabilities, closest to Local Area Network (LAN) speeds for an office building. What is the most expensive solution the network technician can consider?
A.WAN
B.FTTP
C.T-Carrier
D.FTTH
B
The major obstacle to providing WAN access that can approach LAN performance is bandwidth in the last mile. The most expensive solution is Fiber to the Premises (FTTP).
Wide area network (WAN) technologies support data communications over greater distances than local area networks (LANs).
The T-carrier system was developed by the telecommunications provider Bell Labs. This system allows a user to place multiple calls on a single cable.
The major obstacle to providing WAN access that can approach LAN performance is bandwidth in the last mile. The most expensive solution for residential locations is Fiber to the Home (FTTH).
A network engineer wants to establish data communications over a greater distance than a Local Area Network (LAN) for several organizations that use the same public network in a high-rise office building. What can the engineer use to gain the desired distance?
A.WAN
B.T-Carrier
C.Enterprise WAN
D.Digital Subscriber Line
