Answer:
def power(base, expo):
    if expo == 0:
        return 1
    else:
        return base * power(base, expo-1)
Explanation:
*The code is in Python.
Create a method called power that takes base and expo as parameters
Check if the expo is equal to 0. If it is return 1 (This is our base case for the method, where it stops. This way our method will call itself "expo" times). If expo is not 0, return base * power(base, expo-1). (Call the method itself, decrease the expo by 1 in each call and multiply the base)
 
        
             
        
        
        
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>
