1) WAN link
2) Client
3) Server
4) Hub
5) Switch
6) Router
7) Media

A) This serves up resources to a network.
B) It is an older technology that interconnects network components such as clients and servers. It has variable number of available ports.
C) It is a device which makes its forwarding decisions based on logical network addresses.
D) It might be a workstation, laptop, smartphone with wireless capabilities, or a variety of other end-user terminal devices.
E) This device can be copper or fiber-optic cable.
F) It interconnects network components, and it has a variety of port densities. It does not simply take traffic in on one port and blast that traffic out all other ports. Rather, it learns which devices reside off of which ports.

39
Q

When you are interconnecting multiple sites (for example, multiple corporate locations) via WAN links, a hub-and-spoke topology has a WAN link from each remote site (a spoke site) to the main site (the hub site).

True
False

A

True

40
Q

Which of the following statements is true? (Choose two.) It’s about client and servers.

A

Client/server networks can cost more than peer-to-peer networks. For example, client/server networks might require the purchase of dedicated server hardware and a network OS with an appropriate number of licenses.

Client/server networks can easily scale, which might require the purchase of additional client licenses.

A

MAC

42
Q

What is the name of the address that is used by a router (at Layer 3) to identify specific devices?

A

IP

Q

What is the most popular topology that is used on modern LANs?

A

Star

47

True
False

A

True

52
