Answer:
The technician should delete the startup configuration and the "vlan.dat" file residing in the flash memory of the newly added switch and lastly, he should reboot the switch.
Explanation:
In this scenario, a Cisco Catalyst switch has been added to support the use of multiple virtual local area networks (VLANs) as part of an enterprise network. The network technician finds it necessary to clear all virtual local area network (VLAN) information from the switch in order to incorporate a new network design. To accomplish this task successfully, the technician should delete the startup configuration and the "vlan.dat" file residing in the flash memory of the newly added switch and lastly, he should reboot the switch. The VLAN informations are stored in a file with the name "vlan.dat" residing in the flash memory of the switch.
However, in order to delete the startup configuration he would be required to login as an administrator, so as to have all privileges.
<em>Also, the essence of deleting the startup configuration and the "vlan.dat" is to avoid any conflict in the network. </em>
Answer and Explanation:
Reliability is important because if the service lacks lacks reliability this could mean losing a packet or acknowledgement which then requires retransmission.
Delay can be tolerable in different degrees by applications, for example online chatting or conferences need to have the minimum delay possible.
Jitter is the variation in delay for packets belonging to the same flow.
High Jitter: difference between delays is large
Low jitter: difference between delays is small.
Bandwidth depends on the application. In video conferences, for example, there is a need to send million of bits per second to refresh a colour screen while sending a email may not reach even a million.
Answer:

Multiple inheritance causes Diamond problem which happens when:
Class A is parent of class B and C
Now when class D will be inherited from both Class B and C it will have all the members of class A and B which if same will confuse the compiler to import which one?
C++ solves it by using virtual keyword with them and thus telling the compiler which one to inherit.
Java has introduced the interface concept rather then allowing multiple inheritance.
