EastWind [94]

Answer:

Following are the code to the given question:

def shampoo_instructions(num_cycles):#defining a method shampoo_instructions that accepts num_cycles as a parameter

if num_cycles < 1:#defining an if block that num_cycles value is less than 1

print('Too few.')#print message

elif num_cycles > 4:#defining elif block that checks num_cycles is greater than 4

print('Too many.')#print message

else:#defining else block

N= 1;#defining N variable that holds a value 1

for N in range(N, num_cycles+1):#defining for loop that check value in range

print(N , ": Lather and rinse.")#print message

print('Done.')#print message

shampoo_instructions(2)#calling the method

Output:

1 : Lather and rinse.

2 : Lather and rinse.

Done.

Explanation:

In this code, a method "shampoo_instructions" is defined, that accepts a variable "num_cycles" in its parameter, and in the next step, the multiple conditional statements have used that check the "num_cycles" values which can be defined as follows:

The if the block checks the parameter value is less than 1, and it prints the value as the message.
In the next step, the elif block is used that checks parameter value is greater than 4, and it prints the value as the message.
In the else block, it uses the for loop that checks the value in the range and prints its value and calling the method.

When in global configuration mode, which steps are necessary to edit an ip address on an Ethernet interface?

katrin2010 [14]

Answer:

I. You should enter interface configuration mode.

II. Configure the IP address and subnet mask.

Explanation:

A node refers to the physical device that make up a network and are capable of sending, receiving, creating and storing data in communication.

Some examples of network nodes are modem, hubs, computer, switches, phone and printers.

In Computer networking, network devices such as routers and switches are usually configured (programmed) through the use of specific network commands commonly referred to as configs e.g show int description, config terminal (config t), show IP address, etc.

In Cisco devices, there are five (5) main types of command modes;

1. Sub-interface configuration mode.

2. Interface configuration mode.

3. Line configuration mode.

4. Router configuration method.

5. Global configuration mode.

Global configuration mode is a configuration mode that avail network engineers and end users with the ability to modify or edit the running (global) system configuration of a networking device. Thus, any change effected at the global configuration mode will affect the network device as a whole.

In global configuration mode, the steps which are necessary to edit an ip address on an Ethernet interface include;

I. You should enter interface configuration mode using the "configure terminal" command.

II. Configure the IP address and subnet mask.

See an example below;

"Router(config-if)# IP address 192.168.1.2 255.255.255.0"
