Lesson 9 Flashcards
Of the options listed, which is the most used WAN (Wide Area Network) carrier?
- MPLS
- Frame Relay
- Dark Fiber
- Dedicated Lines
MLPS
What factors should you consider in selecting a WAN (Wide Area Network) service provider?
- performance
- cost
- reliability
- all of these
all of these
If you didn’t have access to a highly-skilled IT network team, what would be a good option for a WAN (Wide Area Network)?
- A fully carrier managed WAN.
- A full mesh WAN.
- An unmanaged WAN.
- A self-provided SD-WAN.
A fully carrier managed WAN.
If you wanted to connect a WAN (Wide Area Network) with a high-level of resiliency, what technique would you use?
- A full mesh design.
- A hub and spoke design.
- A star design.
- A bus design.
A full mesh design
What are two common WAN (Wide Area Network) design types?
- MPLS; SD-WAN
- Hub and spoke; Full mesh topology
- Remote singular; Integrated topology
- Main input; Redundant Input
Hub and spoke; Full mesh topology
What is a WAN topology?
WAN topology describes the arrangement concentration routers monitoring the LANs
WAN topology describes the arrangement by which the mesh components within the WAN are distributed
WAN topology describes a system by which the components within the WAN are named
WAN topology describes the arrangement by which components within the WAN are organized
WAN topology describes the arrangement by which components within the WAN are organized
Four types of WAN topologies are _____
Mesh, rind, star, tiered topologies
Mesh, star, ring, bus topologies
Bus, ring, stay, tiered topologies
Ring, star, teared, mess topologies
Mesh, star, ring, bus topologies
In WANs, which of the following is NOT a characteristic of mesh topology?
Implementation incurs high costs
Data transmissions are carried out via multiple routes
All sites are connected to each other
Broadcasts are transmitted over a backbone which is accessible and seen by all connected sites
Broadcasts are transmitted over a backbone which is accessible and seen by all connected sites
Which network topology uses concentration routers to interconnect star network WANs?
Bus topology
Tiered topology
Mesh topology
Ring topology
Tiered topology
In WANs, what advantage does the ring topology have over the bus topology?
Data transmission is multidirectional
Concentration servers stabilize data transmission
It is hardware intensive and so implementation is expensive
Adding and removing nodes is easy
Data transmission is multidirectional
What is a unique downside that consumers face with a traditional cable network connection versus that of DSL?
- None of these answers are correct.
- Overall network stability and reliability are lower.
- Surrounding neighbors can affect the network bandwidth during peak hours.
- The cost per month of service is higher.
Surrounding neighbors can affect the network bandwidth during peak hours.
What are the benefits of a DSL network over the previous method known as dial-up?
- Having much higher network speeds overall.
- Much more stability in terms of network reliability.
- All of these answers are correct.
- Being able to talk on the phone and surf the web at the same time.
All of these answers are correct.
What is one of the major differences between a DSL network and a cable network?
- DSL was more expensive to implement than cable.
- DSL only worked well if the modem was close to the main service area, cable does not have such restrictions.
- DSL is more stable and reliable than cable.
- All of these answers are correct.
DSL only worked well if the modem was close to the main service area, cable does not have such restrictions.
In a cable network environment, what is the name of the cable type that connects from the wall outlet to the modem?
- USB
- Coaxial
- Lightning
- None of these answers are correct.
Coaxial
What makes the symmetric DSL network type so different from the asymmetric type?
- It has higher download speeds.
- None of these answers are correct.
- It has an equal balance between download and upload speeds.
- It has higher upload speeds.
It has an equal balance between download and upload speeds.
