This criterion is linked to a Learning OutcomeCreate checkDuplicates method that receives an array of ints, and an int as parameters. It will return true if the int is found in the array, and false if the int is NOT found in the array. Call the checkDuplicates method from both the MegaMillionsLottery constructor, and the getUserPicks() method.
Answer:
Explanation:
The MegaMillions Lottery class was not provided and neither was the getUserPicks() method. Since they were not found online either, I have created the checkDuplicates method so that it works standalone. Therefore, you can simply call the method from wherever you need by pasting the call line where it needs to be called. A test case has been created in the main method so that you can see the method in action. The output is seen in the attached image below.
public static boolean checkDuplicate(int[] myArr, int element) {
for (int x : myArr) {
if (x == element) {
return true;
}
}
return false;
}

Kareem is working on a project for his manager. He has a few questions for a co-worker who he knows is knowledgeable on the subject. As they're discussing some of the topics, he gives the co-worker permissions to the resources so they can look at the information on their own. Which of the following access control methods does Kareem's company use?
a. DAC
b. RBAC
c. MAC
d. TSAC
Answer: RBAC
Explanation:
The access control methods that Kareem's company uses us the role based access control.
The Role-based access control (RBAC) simply means assigning permissions to users based on the role that such individual plays within an organization.
RBAC is a simple approach to access management and is typically less prone to error than in a scenario whereby permissions are assigned to users individually. Access rights are given to the workers based on what their job entails and what is needed and other information which isn't needed won't be accessible to them.

What are some of the advantages and disadvantages of connection-oriented WAN/Man as opposed to connection-less?
Answer and Explanation:
Connection oriented WAN/MAN as opposed to connection less network is a type of wide area network that requires communicating entities in the network to establish a dedicated connection for their communication before they start communicating. This type of network will use these established network layers only till they release it, typical of telephone networks.
Advantages include:
Connection is reliable and long.
Eliminates duplicate data issues.
Disadvantages include:
Resource allocation while establishing dedicated connection slows down speed and may not fully utilize network resources.
There are no plan B's for network congestion issues, albeit occurring rarely with this type of network.

A.
white box testing
B.
black box testing
C.
acceptance testing
D.
usability testing
Answer:
D. usability testing
Explanation:
A software can be defined as a set of executable instructions (codes) or collection of data that is used typically to instruct a computer how to perform a specific task and to solve a particular problem.
A software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications. There are seven (7) main stages in the creation of a software and these are;
1. Planning.
2. Analysis and requirements.
3. Software design and prototyping.
4. Development (coding).
5. Integration and testing
6. Deployment.
7. Operations and maintenance.
Usability testing is a testing technique used by a software development team to test a developed code rather than just the functionality of the code.
The main purpose of usability (user experience) testing is to determine how easy, user-friendly or difficult it is for end users (real people) to use a software application or program.
Your new trainee is interested in ACLs (access control lists). He asks you want they can be used for. What should you tell him? A. Protect hosts from viruses.B. Classify network traffic.C. Provide high network availability.D. IP route filtering.
Answer:
B. Classify network traffic.
D. IP route filtering.
Explanation:
An access control can be defined as a security technique use for determining whether an individual has the minimum requirements or credentials to access or view resources on a computer by ensuring that they are who they claim to be.
Simply stated, access control is the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication and authorization is used in access control, to ensure a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification
Hence, an access control list primarily is composed of a set of permissions and operations associated with a network or file.
In Computer networking, access control lists (ACLs) can be used to perform the following tasks;
I. Classify network traffic: it can be used to classify the different networks on a router and define whether packets are rejected or accepted.
II. Internet protocol (IP) route filtering: any internet protocol (IP) address that's is not on the accept list would be refused permission into accessing a network. Thus, ACLs can either deny or accept IP addresses depending on the routing table configured on the router.

User-Defined Functions: Miles to track lapsOne lap around a standard high-school running track is exactly 0.25 miles. Define a function named MilesToLaps that takes a float as a parameter, representing the number of miles, and returns a float that represents the number of laps.Then, write a main program that takes a number of miles as an input, calls function MilesToLaps() to calculate the number of laps, and outputs the number of laps. Ex: If the inout is 1.5the output is 6.0 Ex: If the input is 2.2the output is 8.8 Your program should define and call a function Function Miles ToLaps(float userMiles) returns float userLaps 12 // Deine Milestola hert. 34 // Deine Minhert. Your code ust call llestola 5
Answer:
Explanation:
The following is written in Java. The MilesToLaps method creates a variable called laps and gives it the value of the input parameter miles divided by 0.25. Then it returns the variable laps to the user. In the main method a Scanner object was created and asks the user for the number of miles which are passed to the MilesToLaps method which returns the number of laps. This can be seen in the attached image below.
import java.util.Scanner;
class Brainly {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("How many miles?");
float miles = in.nextFloat();
System.out.println("This is " + MilesToLaps(miles) + " laps");
}
public static float MilesToLaps(float miles) {
float laps = (float) (miles / 0.25);
return laps;
}
}
Imagine you are trying to choose what restaurant to visit. You have a list of restaurants, each with a collection of star ratings. You also have a minimum standard; you will only go to a restaurant whose star rating is at least your minimum standard. Write a function called restaurant_rating. restaurant_rating has two parameters. The first is a dictionary, where the keys are restaurant names and the values are lists of ratings. The second parameter is your minimum rating. If a restaurant's average rating is above your minimum rating, you might visit it. If it is not, you won't. restaurant_rating should return a list of restaurants eligible for you to visit. That is, it should return a list of restaurant names from the dictionary whose average ratings (the average of the ratings in their lists) is greater than or equal to your minimum rating. This list should be sorted alphabetically. For example: rest_and_rating
Answer:
The function in Python is as follows:
def restaurant_rating(restaurants,minRatings):
restaurantList = []
for key in restaurants:
if restaurants[key] >= minRatings:
restaurantList.append(key)
restaurantList.sort()
return restaurantList
Explanation:
This declares the function
def restaurant_rating(restaurants,minRatings):
This initializes the list of eligible restaurants
restaurantList = []
This iterates through the restaurant dictionary
for key in restaurants:
If the ratings is greater than or equal to minimum ratings
if restaurants[key] >= minRatings:
The restaurant name is appended to the restaurant list
restaurantList.append(key)
Sort the eligible lists
restaurantList.sort()
Return the list
return restaurantList
