Answer:

Importance of backup in system administration:

Backups are crucial in system administrations for preserving continuity and protecting against specific types of hardware failures, service interruptions, and human mistakes. To aid a company in recovering from an unexpected catastrophe, backup copies make it possible to restore data to a previous point in time. To safeguard against primary data loss or corruption, it is essential to save a copies of data on a different media. When a system administrator create a backup, he makes a copy of the data that you can restore if your main data is lost. These errors may be the consequence of faulty hardware or software, corrupted data, or a human error like a targeted attack or an unintentional deletion. System backup and recovery is therefore a crucial skill for system administrators as well as the companies they work for.

Three methods for performing backup:

  1. Disk image: A efficient method to back up not only the files and directories but also everything else on the system is by creating a disk image. If a user have a disk image, the user can restore everything, including the operating system, applications, data, and more, so the user won't have to worry about any difficulties. Placing the  disk image-containing DVD into the DVD-ROM to restore the backup. Additionally, just attach an external HDD to the computer if the user have a disk image that they made.
  2. External hard drive: The most common backup method is to use an external hard drive or even a USB flash drive. An HDD can be easily, quickly, and affordably backed up. It is effective since consumers may carry their portable backup with them wherever they go.
  3. Cloud backup: Cloud backup or Online backup has been around for a while, but not many people really utilize it. But the greatest backup technique by far is cloud backup. The user does not have to worry about hardware problems because their files are saved in the cloud and can be accessed from anywhere because the backups are automatically produced and everything is synchronized. It is one of the greatest methods to backup, especially when you consider that the contents are encrypted and stored securely.

Consider the following code segment, which is intended to set the Boolean variable inRange to true if the integer value num is g
Natasha_Volkova [10]

Answer:

Option d  num = 50, min = 50, max = 50

Explanation:

Given the code segment:

  1. boolean isBigger;
  2. boolean isSmaller;
  3. boolean inRange;
  4. if (num < max)
  5.        {
  6.            isSmaller = true;
  7.        }
  8.        else {
  9.            isSmaller = false;
  10.        }
  11.        if (num > min)
  12.        {
  13.            isBigger = true;
  14.        }
  15.        else {
  16.            isBigger = false;
  17.        }
  18.        if (isBigger == isSmaller) {
  19.            inRange = true;
  20.        } else {
  21.            inRange = false;
  22.        }

If we have num = 50, min = 50 , max = 50,  the condition num < max will be evaluated to false and therefore isSmaller is set to false.

The condition num > min will be evaluated to false as well and therefore isBigger is set to false.

Since isSmaller and isBigger are both false and therefore isBigger == isSmaller will be evaluated to true and set the inRange = true. This has violated the statement that if the integer value num is greater than min value and less than max value, then only set inRange to true. This is because num = 50 is neither greater than min nor less than max, it is supposedly not in range according to the original intention of the code design.

What is printed by the following program provided all necessary standard header files are included? Explain each line of the out
Ostrovityanka [42]

<u>Output:</u>

f1 in A

f2 in A

f1 in B

f2 in A

f1 in A

f2 in A

f1 in B

f2 in B  

<u>Explanation:</u>

In this snippet, the code makes use of virtual functions. A virtual function is defined as a function that is defined in the base class and redefined in the derived class. If the derived function accesses the virtual function, the program will get executed with the derived class’s version of the function.

In this code, we define the virtual function f1() in class A and also redefine it in class B which is the derived class of A. While executing the program, the function g which takes the object b (class B’s object) as a parameter. It will print class B’s version of f1() rather than class A’s version. This is working off the virtual function.

2.3 Code Practice: Question 2
V125BC [204]

<u>Answer:</u>

<em>feetFab1 = int(input(""Enter the value in feet for the 1st  piece of fabric: ""))</em>

<em>inchFab1 = int(input(""Enter the value in inches for the 1st  piece of fabric: ""))</em>

<em />

<em>feetFab2 = int(input(""Enter the value in feet for the 2nd  piece of fabric: ""))</em>

<em>inchFab2 = int(input(""Enter the value in inches for the 2nd  piece of fabric: ""))</em>

<em />

<em>feetSum = (feetFab1 + feetFab2)</em>

<em>inchSum = (inchFab1 + inchFab2)</em>

<em />

<em>totalFeet = ((inchSum % 12) + feetSum)</em>

<em>totalInch = (feetSum % 12)</em>

<em>print (""Feet: "" + str(totalFeet) + "". Inches: "" + str(totalInch))</em>
