True/False (each question is 2 points)

1. With MPLS, it is possible to define a route based on the source and destination addresses : T/F

2. In CDMA, different users can transmit on the same frequency at the same time: T / F

3. In the hierarchical OSPF, area border routers run multiple instances of OSPF algorithms. T/F

4. An n-bit-CRC can detect with probability 1 any single error burst not longer than n bits. T/F

5. In random access, Carrier Sensing is a technique that guarantees no collision will happen. T/F

6. In Ethernet, due to exponential backoff, if a sender waited for T units of time before sending but experienced a collision, at the next attempt, the sender will wait for 2*T, then resends. T/F

7. ARP is Plug and Play: T/F

8. A MAC address needs to be updated through self learning when the host changes location. T/F

9. The Internet routing protocols require every provider network to advertise every path available through their AS. T/F

10. The Ethernet preamble is used to synchronize the receiver and sender clock rates. T/F
