Answer: ....

If one load balancer fails, the secondary picks up the failure and becomes active. They have a heartbeat link between them that monitors status. If all load balancers fail (or are accidentally misconfigured), servers down-stream are knocked offline until the problem is resolved, or you manually route around them.

Explanation:

Load balancing is a technique of distributing your requests over a network when your server is maxing out the CPU or disk or database IO rate. The objective of load balancing is optimizing resource use and minimizing response time, thereby avoiding overburden of any one of the resources.

The goal of failover is the ability to continue the work of a particular network component or the whole server, by another, should the first one fail. Failover allows you to perform maintenance of individual servers or nodes, without any interruption of your services.

It is important to note that load balancing and failover systems may not be the same, but they go hand in hand in helping you achieve high availability.

The current in a resistor is 5.0 A, and its power is 60 W. What is the voltage?
alexandr1967 [171]

The voltage on a resistor will be "12 V".

According to the given question,

Current,

  • I = 5.0 A

Power,

  • P = 60

As we know the formula,

→ Power (P)= Current(I)\times Voltage (V)

or,

→              V = \frac{P}{I}

By putting the giving values, we get

→                  = \frac{60}{5}

→                  = 12 \ V

Thus the solution above is right.

Write a program that defines an interface having the following methods: addition, subtraction, multiplication, and division. Cre
Tatiana [17]

Hello, you haven't provided the programing language in which you need the code, I'll explain how to do it using Python, and you can follow the same logic to make a program in the programing language that you need.

Answer:

1. # -*- coding: utf-8 -*-

2. #Python  

3. class Calculator:

4.     def add(self):

5.         print(a + b)

6.     def sub(self):

7.         print(a - b)

8.     def mul(self):

9.         print(a * b)

10.     def div(self):

11.         print(a / b)

12.  

13. obj = Calculator()

14. choice = 1

15. while choice != 0:

16.     a = int(input("\nEnter first number: "))

17.     b = int(input("Enter first number: "))

18.      

19.     print("\n0. EXIT")

20.     print("1. DIVISION")

21.     print("2. ADDITION")

22.     print("3. SUBTRACTION")

23.     print("4. MULTIPLICATION")

24.      

25.     choice = int(input("\nEnter your choice: "))

26.     if choice == 1:

27.         obj.div()

28.     elif choice == 2:

29.         obj.add()

30.     elif choice == 3:

31.         obj.sub()

32.     elif choice == 4:

33.         obj.mul()

34.     else:

35.         break

Explanation:

  • From lines 1 to 12 we define the object with four methods, addition, subtraction, multiplication, and division. Each method contains the operation between two variables inside a print function
  • On line 13 we instantiate our class
  • On line 14 we declare the variable choice that is going to store the operation that the user wants to perform
  • On line 15 we declare a while loop, this is going to keep running the program until the user wants to exit
  • From line 16 to 18 we ask the user to enter two numbers
  • From line 19 to 24 we print the possible operation, assigning a number for each operation, this indicates to the user what number to press for what operation
  • On line 25 we ask the user for the operation
  • From lines 26 to 35 we check the user input an accordingly we call the corresponding method to performs the operation
