Answer: Option (B) is correct.
Explanation:
A worm in technical sense is also known as a computer worm which is a self-replicating virus/ malicious content that replicates itself in order to spread to the uninfected PC. They often use components of an OS (operating system) which are automatic and also invisible to an individual. It should be duly noted that it is usual for a computer worm to be observed only when their replication utilizes system content, slowing other tasks at hand.
Answer: I would suggest you consider your audience and how you can connect to them. Is your presentation, well, presentable? Is whatever you're presenting reliable and true? Also, no more than 6 lines on each slide. Use colors that contrast and compliment. Images, use images. That pulls whoever you are presenting to more into your presentation.

Answer:
One of the strategies to avoid nested conditional is to use logical expressions such as the use of AND & operator.
One strategy is to use an interface class with a method. That method can be created to be used for a common functionality or purpose. This is also called strategy design pattern. You can move the chunk of conditional statement to that method. Then each class can implement that interface class and use that shared method according to their own required task by creating objects of sub classes and call that common method for any such object. This is called polymorphism.
Explanation:
Nested conditionals refers to the use of if or else if statement inside another if or else if statement or you can simply say a condition inside another condition. For example:
if( condition1) {
//executes when condition1 evaluates to true
if(condition2) {
//executes when condition1 and condition2 evaluate to true
} else if(condition3) {
//when condition1 is true and condition3 is true
} else {
//condition1 is true but neither condition2 nor conditions3 are true
} }
The deeply nested conditionals make the program difficult to understand or read if the nested conditionals are not indented properly. Also the debugging gets difficult when the program has a lot of nested conditionals.
So in order to avoid nested conditionals some strategies are used such as using a switch statement.
Here i will give an example of the strategies i have mentioned in the answer.
Using Logical Expressions:
A strategy to avoid nested conditionals is to use logical expressions with logical operators such as AND operator. The above described example of nested conditionals can be written as:
if(condition1 && condition2){ //this executes only when both condition1 and condition2 are true
} else if(condition1 && condition3) {
this executes only when both condition1 and condition3 are true
} else if(condition1 ){
//condition1 is true but neither condtion2 nor condtion3 are true }
This can further be modified to one conditional as:
if(!condition3){
// when condition1 and condition2 are true
}
else
// condition3 is true
Now lets take a simple example of deciding to go to school or not based on some conditions.
if (temperature< 40)
{
if (busArrived=="yes")
{
if (!sick)
{
if (homework=="done")
{
printf("Go to school.");
}
}
}
}
This uses nested conditionals. This can be changed to a single conditional using AND logical operator.
if ((temperature <40) && (busArrived=="yes") &&
(!sick) && (homework=="done"))
{ cout<<"Eligible for promotion."; }
The second strategy is to use an interface. For example you can
abstract class Shape{
//declare a method common to all sub classes
abstract public int area();
// same method that varies by formula of area for different shapes
}
class Triangle extends Shape{
public int area() {
// version of area code for Triangle
return (width * height / 2);
}
}
class Rectangle extends Shape{
public int area() {
// version of area code for Rectangle
return (width * height)
}
}
// Now simply create Rectangle or Triangle objects and call area() for any such object and the relevant version will be executed.
B. Initiate a confidential data exfiltration process
C. Look for known vulnerabilities to escalate privileges
D. Create an alternate user ID to maintain persistent access
Answer:
D.
Explanation:
Based on the information provided surrounding this scenario, it can be said that the most likely next course of action would be to create an alternate user ID to maintain persistent access. This would allow the attacker to have continuous access into the network in the case that the system administrators detect that the operator's user ID and password have been compromised. Thus also giving the attacker ample time to infiltrate and find vulnerabilities in the network through an alternate hidden user ID.
Answer:
Hi!
The answer coded in Javascript is:
function minimalNumbersOfBanknotes(input) {
var banknotes = [50, 20, 10, 5, 1];
var output = '';
//Each while writes on output variable the banknote and substract the same quantity on input variable.
//If the input is lesser than the value of while banknote, step into next while.
for (var i = 0; i < banknotes.length; i++) {
while(input >= banknotes[i]) {
output = output + ' ' + banknotes[i];
input = input - banknotes[i];
}
}
return output;
}
Select one:
a. 1 or 2
b. 2
c. 3
d. 1
e. None
Answer:
b. 2
Explanation:
As we know operator + is supported by the class.Since we know that the + operator binary operator means it needs two operands to work upon it cannot work on one operand.++ operator is unary operator it works on one operand only.
For example:-
a+b
a++.
Hence we conclude that the answer is 2.
