What is required for a network to be a part of Internet?
Having IP addressing, implementing Ethernet
Understanding TCP/IP suite, forming star topology
Having IP addressing, understanding TCP/IP suite
Using routers, having IP addressing
Internet is based on:
Circuit-switching
Packet-switching
Neither of the above
Which type of communication provides Quality of Service guarantees and simpler routing?
Circuit-switching
Packet-switching
Which of the statements below are true?
Routing enables remote end-points exchange data with one another through the global infrastructure.
Routing is not needed for circuit-switching.
A router decides where to forward a packet based on routing table.
An intermediate router can only forward the packet to the next router on the way to destination.
What does it mean that the Internet connection is asymmetric?
The bit-rates for up-link (upload) and down-link (download) are different.
The length of physical medium between the device and the core network for up-link is different that for down-link.
The connection is ment to be used more often for either down-link or up-link.
Why do we need OSI model with a lot of protocols in a stack (and not e.g. One protocol for all the functionality of the network)?
For commercial reasons (imposed by the market).
To make it feasible to introduce new applciations and more optimised/tailored technologies.
OSI stack is a result of lack of consensus between NW engineers; it is hard to get rid of it now.
To separate network functions into manageable portions.
OSI Layer 2 (Data link) handles...
Physical addressing.
Logical addressing.
OSI Layer 3 (Network) handles...
Logical addressing.
Physical addressing.
Which protocol is NOT a transport (OSI layer 4) protocol?
TCP
UDP
HTTP
It's year 2018. I want to set up a Ethernet LAN in my house. I go to the shop and buy:
A hub.
A switch.
1000BaseT twisted-pair cables.
10Base5 coax cables.
The ability for a switch to automatically discover physical addresses of the devices connected with it is called:
Switching.
BigMAC.
MAC learning.
Autoconfiguration.
How do the WiFi devices (stations) know that there are some WiFi networks they can join?
They do not know.
The Access Points inform them from time to time.
They need to download a configuration file.
They try to connect to all possible ESSIDs until they reach an active network.
A type of network where only peers are connected (no base station/access point/other infrastructure) is called:
Voilla network.
Ad-libitum network.
Ad-hoc network.
How many devices can actively take part in communication within one Bluetooth piconet? [Master and Slaves]
7
255
8
6
"Stop warming up the pasta, shut down the microwave oven, stop ruining my network!!!". These words would NOT be shouted out by the administrator of:
Bluetooth piconet.
WiFi BSS.
Zigbee network.
Sigfox network.
Which of the following technologies operate in sub-GHZ band (less than 1 GHz)?
WiFi.
LoRaWAN.
Sigfox.
Zigbee.
NFC.
What is RFID tag?
A successor of hashtag in social media.
One of the control fields in ETH frame.
A passive NFC device storing some data to be fetched via inductive coupling.
Near Field Communication is used for cashless payments or authenticated access in offices. Can I use it to share a picture from my phone with a dude standing next to me? [He has a smartphone too]
No.
Yes.
Does the audio transmision in Bluetooth happen over IP?
Yes.
No.
Which Low-power technology enables localisation by means of time of arrival comparison?
Zigbee.
Bluetooth.
LoRaWAN.
NFC.
