Answer:
b. The Hello timer as configured on the root switch.
Explanation:
There are differrent timers in a switch. The root switch is the only forwarding switch in a network, while non root switches blocks traffic to prevent looping of BPDUs in the network. Since the root switch is the only forwarding switch, all timing configuration comes from or is based on the configuration in the root.
The hello timer is no exception as the nonroot switch only sends 802.1D DTP hello BPDU messages forwarded to it by the root switch and its frequency depends on the root switch hello timer.
Answer:
def floor_sum(number1, number2):
total = number1 + number2
if total >= 0:
return int(total)
else:
return int(total) - 1
print(floor_sum(1.1, 3.05))
Explanation:
*The code is in Python.
Create a function called floor_sum that takes two parameters, number1 and number2
Sum them and set it to the total
Check if the total is positive number or 0, return the integer part of the total. Otherwise, subtract 1 from the integer part of the total and return it.
Call the function with given parameters in the question and print the result
Note that if the result is a negative value like -5.17, the floor of the result is -6 not -5.
Answer:
I am writing the Python program. Let me know if you want the program in some other programming language. Here is the Python code:
class Student(object):
def __init__(a,score=10):
a.score=score
def add_score(a,score):
a.score += 10
return (score)
def decrease_score(a,score):
a.score -=10
return (score)
def __str__(a):
current_score="{}".format(a.score)
return current_score
Explanation:
The program has a Student() class with attribute score.
It has the following methods:
__init__(): This method works as a constructor and enables to initialize score attribute of Student class. The value of score is initialized to 10. I have used a as the instance of Student class. However self keyword can also be used as an instance of the object to access the attributes and methods of Student class.
add_score() This method is used to add 10 to the score.
decrease_score() This method is used to decrease the score by 10.
__str__() This method is used to return the current score. format() is used here to return a string. current_score holds the value of the current score.
If you want the check the working of the program, then you can use the following statements to see the results on the output screen:
p = Student()
print(p)
p.add_score(p)
print(p)
This will create an object p of Student class and calls the above methods to display the values of the score according to the methods.
The program along with its output is attached.
Normally active directory once is corrupted best method is to repair the active directory. As IT administrator user has keep a proper backup either date wise or weekly wise.
<u>Explanation:</u>
If IT administrator doesn’t have enough backup restore or repairing the active directory is highly impossible.
Before restore proper information to be made and rebooted the domino server and selected advance boot option and select the restore options. And select the proper and good backup and restore it. After restoring the backup domain server started and domain active directory should work proper.
As experience better to reinstall domain server and active directory is good practice.
