Security monitoring has detected the presence of a remote access tool classified as commodity malware on an employee workstation. Does this allow you to discount the possibility that an APT is involved in the attack
Answer:
No it doesn't
Explanation:
Targeted malware can be linked to such high resource threats as APT. Little or nothing can be done to stop such advanced persistent threats. It is necessary to carry out an evaluation on other indicators so that you can know the threat that is involved. And also to know if the malware is isolated or greater than that.
A ___________ consists of a large number of network servers used for the storage, processing, management, distribution, and archiving of data, systems, web traffic, services, and enterprise applications.

Consider the following class definitions.public class Bike{private int numWheels = 2;// No constructor defined}public class EBike extends Bike{private int numBatteries;public EBike(int batteries){numBatteries = batteries;}}The following code segment appears in a method in a class other than Bike or EBike.EBike eB = new EBike(4);Which of the following best describes the effect of executing the code segment?А. An implicit call to the zero-parameter Bike constructor initializes the instance variable numwheels. The instance variable numBatteries is initialized using the value of the parameter batteries.
B. An implicit call to the one-parameter Bike constructor with the parameter passed to the EBike constructor initializes the instance variable numwheels. The instance variable numBatteries is initialized using the value of the parameter batteries. C. Because super is not explicitly called from the EBike constructor, the instance variable numWheels is not initialized. The instance variable numBatteries is initialized using the value of the parameter batteries.
D. The code segment will not execute because the Bike class is a superclass and must have a constructor. E The code segment will not execute because the constructor of the EBike class is missing a second parameter to use to initialize the numWheels instance variable.
Answer:
The answer is "Option A".
Explanation:
Please find the complete program in the attached file.
The given program includes a super-class Bike having a private integer numWheels parameter. The class EBike inherits the class Bike, EBike comprises one parameter function Object() which utilizes its variable number of the private integer Battery level of the battery parameter and the wrong choice can be defined as follows:
In choice B, it is wrong since there is no constructor with a single argument in the Bike class.
In choice C, it is wrong since there no need to call the base class constructor with the super keyword.
In choice, D is wrong because there no need to create a constructor of the base class.
In choice, E is wrong because it does not require the second EBike constructor parameter.
The statement that best describes the effect of executing the code segment is (a) an implicit call to the zero-parameter Bike constructor initializes the instance variable numwheels. The instance variable numBatteries is initialized using the value of the parameter batteries.
Given that the following object is defined in another class (say the Main class)
EBike eB = new EBike(4);
Also, the class Bike is a super class of the class EBike, where Ebike inherits the properties of class Bike.
It means that:
Option (a) is correct.
This is so, because:
An implicit call of one parameter to class cannot be used, as in option B.It is not necessary to call the Bike class, as in option C.It is not necessary to create a constructor of the EBike class, as in option D.Read more about classes at:

What aspect should you consider before adding pictures to a document?
You should structure the BLANK first before you search for a relevant picture.
Answer:
You should structure the text first before you search for a relevant picture.
Explanation:
When adding a picture or pictures to a text document, the structure of the text must be considered.
Structure as used in the above sentence means (but is not limited to), the headings, the layouts, the spacing, paragraphs and word formatting in the document.
In other words, the way the document is organized
All these must be put in to place before one adds pictures into the document.
Write a program that tells what coins to give out for any amount of change from 1 cent to 99 cents. For example, if the amount is 86 cents, the output would be something like the following:
86 cents can be given as 3 quarters 1 dime and 1 penny
Use coin denominations of 25 cents (quarters), 10 cents (dimes), and 1 cent (pennies). Do not use nickel and half dollar coins. Your program will use the following function (among others):
void computeCoin(int coinValue, int& number, int& amountLeft);
For example, suppose the value of the variable amountleft is 86. Then, after the following call, the value of number will be 3 and the value of amountLeft will be 11 (because if oyu take three quarters from 86cents, that leaves 11 cents):
computecoins (25, number, amountLeft);
Include a loop that lets the user repeat this computation for new input values until the suer says he or she wants to end the program (Hint: use integer division and the % operator to implement this function.)
Add all numbers up
and you will get your sum
Calculate the boiling point of 3.42 m solution of ethylene glycol, C2H602, in water (Kb =0.51°C/m, the normal boiling point of water is 100°C):
Answer:
128.10 degree Celsius
Explanation:
The boiling point is given by
[tex]T_b = \frac{1000*K_b * w}{M*W}[/tex]
Substituting the given values, we get -
[tex]T_b = \frac{1000*0.51 * 3.42}{62.07}\\T_b = 28.10[/tex]
Tb is the change in temperature
T2 -T1 = 28.10
T2 = 28.10 +100
T2 = 128.10 degree Celsius
Write a program that repeatedly shows the user a menu to select the shape form three main shapes or to print the shapes created so far. If the user selects to create a new shape, the program prompts the user to enter the values for the size of the selected shape (How many of the selected shape user wants to create). The shape is then stored in an array. If the user selects to print the current shapes, print the name and the total area of each shape to the console.
Answer:
Explanation:
The following code is written in Python. It creates a program that keeps printing out a menu allowing the user to create shapes. These shapes are saved in an array called shapes. Once the user decides to exit, it prints all of the shapes in the array along with their total area. The output can be seen in the attached picture below. Due to technical difficulties, I have added the code as a txt file below.
Calculate the total capacity of a disk with 2 platters, 10,000 tracks, an average of
400 sectors per track, and 512 bytes per sector?
Answer:
[tex]Capacity = 2.048GB[/tex]
Explanation:
Given
[tex]Tracks = 10000[/tex]
[tex]Sectors/Track = 400[/tex]
[tex]Bytes/Sector = 512[/tex]
[tex]Platter =2[/tex]
Required
The capacity
First, calculate the number of Byte/Tract
[tex]Byte/Track = Sectors/Track * Bytes/sector[/tex]
[tex]Byte/Track = 400 * 512[/tex]
[tex]Byte/Track= 204800[/tex]
Calculate the number of capacity
[tex]Capacity = Byte/Track * Track[/tex]
[tex]Capacity= 204800 * 10000[/tex]
[tex]Capacity= 2048000000[/tex] --- bytes
Convert to gigabyte
[tex]Capacity = 2.048GB[/tex]
Notice that the number of platters is not considered because 10000 represents the number of tracks in both platters

Question Statement: Explain the steps needed to the display all the items in a linked list
Answer:
A list of linked data structures is a sequence of linked data structures.
The Linked List is an array of links containing items. Each link contains a link to a different link. The second most frequently used array is the Linked List.
Explanation:
Create a node class with 2 attributes: the data and the following. Next is the next node pointer.
Create an additional class with two attributes: head and tail.
AddNode() adds to the list a new node:
Make a new node.
He first examines if the head is equal to zero, meaning that the list is empty.
The head and the tail point to the newly added node when this list is vacant.
If the list isn't empty, the new node will be added at the end of the list to point to the new node of tail. This new node is the new end of the list.
Show() will show the nodes in the list:
Set a node current that first points to the list header.
Cross the list until the current null points.
Show each node by referring to the current in each iteration to the next node.

second = Convert.ToInt32(secondString);
product = first * second;
Write("Thank you, {0}. The product of {1} and {2} is {3}", name,first, second, product);

}
Explanation:
string name;string firstString, secondString; ----- Replace secondSting with secondString,
int first, second, product;
Write("Enter your name >> "); --- Here, the quotes must be closed with corresponding quotes "
name = ReadLine(); The syntax of readLine is incorrect without the () brackets
Write("Hello, {0}! Enter an integer >> ", name);
firstString = ReadLine();
first = Convert.ToInt32(firstString); There is a dot between Convert and ToInt32
Write("Enter another integer >> ");
secondString = ReadLine(); --- Readline() should be written as ReadLine()
second = Convert.ToInt32(secondString);
product = first * second;
Write("Thank you, {0}. The product of {1} and {2} is {3}", name,first, second, product); --- The formats in {} should start from 0 because 0 has already been initialized for variable name

A notebook computer is set up to take maximum advantage of power saving features including shutting down the display and the hard disk after periods of inactivity. A user sometimes runs UNIX programs in text mode, and at other times uses the X Window System. She is surprised to find that battery life is significantly better when she uses text-only programs. Why
Answer:
The reason is that the windowing system consumes significantly more memory and virtual memory than the text mode.
Explanation:
The reason behind the occurrence of this is that the windowing system consumes significantly more memory and virtual memory than the text mode. As a result, this reduces the likelihood of the hard disk becoming inactive for long enough for it to be powered down by itself with no direct human control, i.e. automatically.

Create a static method that: - is called appendPosSum - returns an ArrayList - takes one parameter: an ArrayList of Integers This method should: - Create a new ArrayList of Integers - Add only the positive Integers to the new ArrayList - Sum the positive Integers in the new ArrayList and add the Sum as the last element For example, if the incoming ArrayList contains the Integers (4,-6,3,-8,0,4,3), the ArrayList that gets returned should be (4,3,4,3,14), with 14 being the sum of (4,3,4,3). The original ArrayList should remain unchanged.
Answer:
The method in Java is as follows:
public static ArrayList<Integer> appendPosSum(ArrayList<Integer> nums) {
int sum = 0;
ArrayList<Integer> newArr = new ArrayList<>();
for(int num : nums) {
if(num>0){
sum+=num;
newArr.add(num); } }
newArr.add(sum);
return newArr;
}
Explanation:
This defines the method; it receives an integer arraylist as its parameter; nums
public static ArrayList<Integer> appendPosSum(ArrayList<Integer> nums) {
This initializes sum to 0
int sum = 0;
This declares a new integer arraylist; newArr
ArrayList<Integer> newArr = new ArrayList<>();
This iterates through nums
for(int num : nums) {
If current element is greater than 0
if(num>0){
This sum is taken
sum+=num;
And the element is added to newArr
newArr.add(num); } }
At the end of the iteration; this adds the calculated sum to newArr
newArr.add(sum);
This returns newArr
return newArr;
}

Write a program whose inputs are three integers, and whose output is the smallest of the three values. Ex: If the input is: 7 15 3 the output is: 3
Answer:
The program in Python is as follows:
nums = []
for i in range(3):
num = int(input(""))
nums.append(num)
print(min(nums))
Explanation:
This initializes a list of numbers
nums = []
This loop is repeated 3 times
for i in range(3):
For each repetition, this prompts the user for input
num = int(input(""))
This appends the input to the list
nums.append(num)
This gets the smallest of the three inputs using the min() function. The smallest is also printed
print(min(nums))

Implement a program that manages shapes. Implement a class named Shape with a method area() which returns the double value 0.0. Implement three derived classes named Rectangle, Square, and Circle. Declare necessary properties in each including getter and setter function and a constructor that sets the values of these properties. Override the area() function in each by calculating the area using the defined properties in that class.
Answer:
Explanation:
The following code is written in Python. It creates the parent class Shape and the three subclasses Rectangle, Square, and Circle that extend Shape. Shape has the constructor which is empty and the area method which returns 0.0, while the three subclasses take in the necessary measurements for its constructor. Each subclass also has getter and setter methods for each variable and an overriden area() method which returns the shapes area.
class Shape:
def __init__(self):
pass
def area(self):
return 0.0
class Square(Shape):
_length = 0
_width = 0
def __init__(self, length, width):
self._width = width
self._length = length
