Question 2
How do protocols such as ATM and Frame-Relay support differentiating multiple customers or traffic types on the same physical wire?
  1. ATM and Frame-Relay are circuit switched protocols and use Virtual Circuits to create logical separation of traffic.
  2. ATM and Frame-Relay are point-to-point protocols and do not support different customers or traffic type on the same physical wire.
  3. ATM and Frame-Relay are circuit switched protocols and use VLAN's to create logical separation of traffic.
  4. ATM and Frame-Relay are circuit switched protocols and use IP Header information to create logical separation of traffic.
Correct answer: A
Question 3
Which of the following is the best description of well known ports?
  1. Well known ports apply to routers only and are used for communication and control traffic. Well known port numbers are assigned by IANA and can have any value.
  2. Well known ports are used by TCP and UDP. Well known port numbers range from 1024 to 65535 and are assigned by IANA.
  3. Well known port numbers are used by both TCP and UDP. Well known port numbers range from 1 to 1023 and are assigned by IANA.
  4. Well known ports numbers are used by TCP only. Well known port numbers are assigned by IANA and can have any value.
