Answer:
E) Supertype/subtype relationship
Explanation:
The type of relationship pattern illustrated in the schema below is E) Supertype/subtype relationship
Supertype/subtype relationship is the types of relationship that exist in the form of parent - children relationship in an entity. The supertype entity is the parent while the subtype entity is the child. The supertype entity contains one or more attributes that is common to the subtype entity.
The schema first define the Supertype entity:
VEHICLE (VehicleID, Cost)
CAR (VehicleID, NumberOfSeats)
TRUCK (VehicleID, CargoCapacity)
Then, the following (subtype entity) make reference to the Supertype:
VehicleID in CAR must exist in
VehicleID in VEHICLE
VehicleID in TRUCK must exist in
VehicleID in VEHICLE.
Since the subtype is making reference to supertype, we can say the relationship pattern illustrated in the schema is: Supertype/subtype relationship.
Which of the following is a basic concept associated with Web 2.0? Select one: a. shift in user's role from the passive consumer of content to its creator b. shift in user's interest from sharing information to finding information c. shift in user's preference from online sites to encyclopedias as sources of unbiased information d. shift in user's preference to environment-oriented products e. shift in user's lifestyle due to increased purchasing power
Answer:
A: shift in user's role from the passive consumer of content to its creator
Explanation:
During the phase of Web 2.0, consumers evolved from just been highly informed and socially connected (in other words, they evolved from being just passive consumers) to a more engaged and empowered consumer. This implied that consumers could easily adapt to new technologies to meet individual needs and create an emotional bond with brands. They evolved from passive consumers to being the creators of what they wanted to meet their specific needs.
Given the class 'ReadOnly' with the following behavior: A (protected) integer instance variable named 'val'. A constructor that accepts an integer and assigns the value of the parameter to the instance variable 'val'. A method name 'getVal' that returns the value of 'val'. Write a subclass named 'ReadWrite' with the following additional behavior: Any necessary constructors. a method named 'setVal' that accepts an integer parameter and assigns it the the 'val' instance variable. a method 'isDirty' that returns true if the setVal method was used to override the value of the 'val' variable.
Answer:
I believe you want a subclass so here it is!
public class ReadWrite extends ReadOnly {
public ReadWrite(int initialValue){
super(initialValue);
}
private boolean modified = false;
public void setVal(int x) {
val = x;
modified = true;
}
public boolean isDirty() {
return modified;
}
}

In a typical system design specification, the _____ section describes the constraints, or conditions, affecting a system, including any requirements that involve operations, hardware, systems software, or security.A. time and cost estimatesB. system environmentC. executive summaryD. implementation requirements
Answer:
Option B is the correct answer for the above question.
Explanation:
The system design specification is used to tell the quality and nature of any software or system. So there are needs of one section which tells about the necessary hardware and the software which are used to operate the software or system. This section is known as the "System environment".
The above question also asked the same, hence option B is the correct answer while the other is not because:-
Option A states about time and cost which is not a section of a System design specification.Option C states about executive summary which is not a section of a System design specification.Option D states about implementation requirements which is not a section of a System design specification.

man who is colorblind marries a woman who has normal color vision and is not a carrier of color blindness. If this couple has a son, what are the chances he will be colorblind? Could they have a colorblind daughter? HTML EditorKeyboard Shortcuts
Answer:
Each of their sons has around a 0% chance for being color blind.
they will have normal girls but they will be carriers
Explanation:
Since the man is colour blind and he donates the X- Chromosome that is the carrier to the woman, they will give birth to a daughter who is a carrier but not color blind. If the man donates the Y chromosome, then they will give birth to a normal male child who is not color blind neither is he a carrier
If $hourlyWage contains the value 10.00 and $hoursWorked contains the value 20, what value will $bonus contain after the following code is executed?
if ($hourlyWage >= 10 and $hoursWorked <= 20)
$bonus = $25.00;
else
$bonus = $50.00;
Answer:
$25.00
Explanation:
The variable $bonus will contain $25.00 because the if statement has the condition greater than or equals to for hourlyWage and less than or equals to for hoursWorked. Therefore the if condition evaluates to true since we are given in the question that;
$hourlyWage = 10.00 and $hoursWorked = 20
And the statement following the if is executed ignoring the else statement

A Soprano singer is going to have a higher pitched voice or a lower pitched voice?
Answer:
Higher voice
Explanation:
A soprano singer has a higher pitched voice than other female vocal ranges such as alto. The soprano voice range is the highest for females, capable of singing above middle C.
A soprano singer will have a higher pitched voice compared to an alto, who has a lower pitched female vocal range. In Western music, voice ranges are categorized into four main types: soprano and alto for females, and tenor and bass for males, with soprano being the highest female voice type and bass being the lowest male voice type.
The human voice functions as a wind instrument, with the vocal cords creating vibrations that vary in tension to produce different pitches, making the soprano voice range capable of singing almost exclusively above middle C, which results in higher pitches.

Explanation:
What is the value of routeNumber after the following statement is executed if the value of zipCode is 93705? switch (zipCode) { case 93705: case 93706: routeNumber = 1; break; case 93710: case 93720: routeNumber = 2; break; default: routeNumber = 0; break; }
Answer:
The output of the given code is "1".
Explanation:
In the given switch case code, a switch is used in which a variable routeNumber is defined that accepts an integer value, inside the switch statement inner case is used, which can be described as follows:
In the first case, two case value is check that is "93705 and 93706", in which any of the value is found it will routeNumber value to 1 then break the statement. If the above case value does not match then it will go to the next case, in this case, we also check two values that are "93710 and 93720", if any of the value is found it will routeNumber value to 2 then break the statement. If both of the above condition is false it will go to default then it will routeNumber value to 0 then break the statement, but in this ZipCode value is "93705", so it will found in case 1 then it will return a value that is equal to 1.If r is an instance of the above Person class and oddNum has been declared as a variable of type boolean, which of the following correctly sets oddNum to true if Person object r has an odd number of children and to false otherwise?
oddNum = ( ( r.numChildren() % 2 ) != 0 );
if ( ( r.numChildren() % 2 ) == 0 )
oddNum = false;
else
oddNum = true;
oddNum = false;
for ( int k = 0 ; k < r.numChildren() ; k++ )
oddNum = !oddNum;
I only
II only
III only
I and II only
I, II, and III
Answer:
I, II, and III
Explanation:
The three are almost saying the same thing. the loop is one am a bit concerned about. but since the oddnum is set to false, the loop will work.
The one and two are pretty clear. to test for odd number, the easiest is to divide by two to see if there will be a remainder. That is what both first and second statement is trying to do.

You have recently been called to troubleshoot network connectivity problems at a user's workstation. You have found that the network cable runs across high-traffic areas on the floor, causing the cables to wear through and break. You have replaces the cable with a plenum rated, shielded, twisted pair cable. You would like to minimize the problem and prevent it from happening again. What should you do?
Answer:
The answer is "Pass the cable into the ceiling instead of over the floor".
Explanation:
Network access explains the complex process of link different parts of the network with each other, e.g. while using switches, routers, and access points, and whether, that system works.
To replace the cable with a pair cable graded in plenum, covered, twisted. We use the cable to pass through the ceiling rather than through the concrete, eliminating the issue and stopping it from occurring again.Assuming that interface Resizable is declared elsewhere, consider the following class declaration:
public class InnerClassExample
{
public static void main(String[] args)
{
class SizeModifier implements Resizable
{
// class methods
}
__________________________ // missing statement
}
}
Which declarations can be used to complete the main method?
Answer:
The answer is "Resizable something = new SizeModifier();".
Explanation:
In the given code a class "InnerClassExample" is defined, inside the class the main method is declared, in which a class "SizeModifier" is declared, that inherits the interface, that is "Resizable".
Inside of the main method, we create an interface object, which is "something", in which the "SizeModifier" class is used to call as an instance or constructor. In this question only answer section code is correct, and others were wrong because it is not declared in the question.What is the output of the following code? import java.util\.\*; public class Test { public static void main(String[] args) { List list1 = new ArrayList<>(); list1.add("Atlanta"); list1.add("Macon"); list1.add("Savanna"); List list2 = new ArrayList<>(); list2.add("Atlanta"); list2.add("Macon"); list2.add("Savanna"); List list3 = new ArrayList<>(); list3.add("Macon"); list3.add("Savanna"); list3.add("Atlanta"); System.out.println(list1.equals(list2) + " " + list1.equals(list3)); } }
Answer:
true false
Explanation:
list1 is assigned as Atlanta, Macon, Savanna
list2 is assigned as Atlanta, Macon, Savanna
list3 is assigned as Macon, Atlanta, Savanna
After these assignments,
The program checks if lis1 is equal to list2 and prints the result. Since both lists are equal, it will print true
The program checks if lis1 is equal to list3 and prints the result. Even though both lists contain the same elements, the order is different, it will print false.

Cisco Next Generation Intrusion Prevention System (NGIPS) devices include global correlation capabilities that utilize real-world data from Cisco Talos. To leverage global correlation in blocking traffic, what should be configured on the NGIPS?
To configure and set up Sourcefire NGIPS–managed devices, you must define blocking rules, set up the IPS to capture traffic, and, if necessary, block untrusted IP addresses. Sourcefire NGIPS is widely deployed in many enterprise environments that help protect the perimeter from intrusions.
Review the Sourcefire Installation Guides to set up a Defense Center and managed devices. The appliance will be configured as a Next Generation firewall.
Log in to the Sourcefire management interface and select the device you have configured.
Sourcefire NGIPS Interfaces Tab
Enter the specific details within the Device section. Click the pencil icon to edit the device-specific details.
Sourcefire Managed Device Setup
We have two separate security zones created on this device: the BIG-IP load balanced security zone, which is the zone for all the IPS-managed device interfaces, and the VLAN-35 security zone, which is the network for all the application server nodes (i.e., FTP, HTTPS, WEB). The Sourcefire NGIPS– managed device will inspect network flows coming from the BIG-IP appliance and then connect to the back-end server pools.
In this exercise, you will write some code that reads n unique (no duplicates!) non-negative integers, each one less than fifty (50). Your code will print them in sorted order without using any nested loops-- potentially very efficient! We'll walk you through this: First, assume you are given an int variable n, that contains the number of integers to read from standard input. Also assume you are given an array, named wasReadIn, of fifty (50) bool elements and initialize all the elements to false. Third, read in the n integers from the input, and each time you read an integer, use it as an index into the bool array, and assign that element to be true-- thus "marking" in the array which numbers have been read. Lastly the "punchline": write a loop that traverses the bool array: every time it finds an element that is true it prints out the element's INDEX -- which was one of the integers read in. Place all the numbers on a single line, separated by a single spaces. Note: this technique is not limited to 50 elements-- it works just as well for larger values. Thus, for example you could have an array of 1,000,000 elements (that's right-- one million!) and use it to sort numbers up to 1,000,000 in value!
Answer:
// This program is written in C++
// It sorts array of n distinct elements in ascending order
// Comments are used for explanatory purpose
// Program starts here
#include <iostream>
using namespace std;
// Declare a maximum of 50
#define MAX 50
int main()
{
//The next line declares the array of 50 maximum integers
int Readln[MAX];
// The next line declares length of array
int n;
int temp;
// Prompt user to enter length of array
cout<<"Length of Array: ";
cin>>n;
//Check if length falls within range of 2 to MAX
while (n<2 || n>MAX)
{
cout<<"Array must have at least 2 elements and can't be more than "<<MAX<<endl;
}
// The next line declares an input element
int digit;
// The next loop statement accepts distinct array elements
for(int i=0; i<len;i++)
{
cout<<"Enter element ["<<i+1<<"] ";
cin>>digit;
// Check if digit is non-negative and less than 50; repeat until element is within range
while (digit<0 || n>49)
{
cout<<"Acceptable range is 0 to 49";
cin>>digit;
}
Readln[i] = digit;
}
//The next iteration sorts the array
for(i=0;i<n;i++)
{
for(int j=i+1;j<n;j++)
{
if(Readln[i]>Readln[j])
{
// Swap Elements
temp =Readln[i];
Readln[i]=arr[j];
Readln[j]=temp;
}
}
}
// The next line prints array elements

A derived class has access to __________.
a. the public functions and variables of its ancestor classes.
b. the private functions and variables of its ancestor classes.
c. only the functions and variables defined it its class.
d. none of the above.
Answer:
Option a is the correct answer for the above question
Explanation:
The derived class is a class that inherits the property of the base class, and he can access the public variable and function or members of the base class or ancestor class.
Option 'a' also states the same and the question asked about the assessment of the derived class. Hence option a is the correct answer while the other is not because:-
Option b states about the private members, but it is not accessible by the derived class. Option c states about the derived class members but it can also access the base class members.Option d none of the above, but option a is the correct answer.
