data?
A Router
B Server
C LAN
D Client Answer- C
What network type would help facilitate communications when large video or audio files
need to be housed and transferred through the network?
A WLAN
B CAN
C PAN
D SAN Answer- D
,A company has various locations in a city interconnected using Metro Ethernet
connections. This is an example of what type of network?
A WAN
B CAN
C PAN
D MAN Answer- D
How many WAN links are required to create a full mesh of connections between five
remote sites?
A 20
B5
C 10
D 15
Hint: Remember, the formula for the number of connections required for the full-mesh
topology is n(n-1)/2, where n is the number of nodes. So, in this case, 5(5-1)/2 is 10.
