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.
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.

Explanation:
What are the advantages of using a database management system (DBMS) over using file-based data storage?
Answer:
Advantage of DBMS over file system
No redundant data: Redundancy removed by data normalization. No data duplication saves storage and improves access time.
Data Consistency and Integrity: As we discussed earlier the root cause of data inconsistency is data redundancy, since data normalization takes care of the data redundancy, data inconsistency also been taken care of as part of it
Data Security: It is easier to apply access constraints in database systems so that only authorized user is able to access the data. Each user has a different set of access thus data is secured from the issues such as identity theft, data leaks and misuse of data.
Privacy: Limited access means privacy of data.
Easy access to data – Database systems manages data in such a way so that the data is easily accessible with fast response times.
Easy recovery: Since database systems keeps the backup of data, it is easier to do a full recovery of data in case of a failure.
Flexible: Database systems are more flexible than file processing systems

If we were ever to use this pizza ordering program again, we would want to use mainline logic to control its execution. The way it is written, it will automatically execute as soon as it is imported.
Re-write this program, enclosing the top level code into the main function. Then execute the main function. Enter appropriate input so the output matches that under Desired Output.
# Define Function
def pizza(meat="cheese", veggies="onions"):
print("You would like a", meat, "pizza with", veggies)
# Get the User Input
my_meat = input("What meat would you like? ")
my_veggies = input("What veggie would you like? ")
# Call the Function
pizza(meat=my_meat, veggies=my_veggies)
desired output:
What meat would you like? cheese
What veggie would you like? onions
You would like a cheese pizza with onions
2) We want to generate 5 random numbers, but we need the random module to do so. Import the random module, so the code executes.
# Define main function
def main():
print("Your random numbers are:")
for i in range(5):
print(random.randint(1, 10))
# Call main function
main()
desired output:
Your random numbers are:
[x]
[x]
[x]
[x]
[x]
Answer:
Explanation:
The Python program has been adjusted. Now the pizza ordering function is called from the main() method and not as soon as the file is imported. Also, the random package has been imported so that the random.randint(1,10) can correctly create the 5 random numbers needed. The code has been tested and the output can be seen in the attached image below, correctly matching the desired output.
import random
def pizza(meat="cheese", veggies="onions"):
print("You would like a", meat, "pizza with", veggies)
def main():
# Get the User Input
my_meat = input("What meat would you like? ")
my_veggies = input("What veggie would you like? ")
# Call the Function
pizza(meat=my_meat, veggies=my_veggies)
print("Your random numbers are:")
for i in range(5):
print(random.randint(1, 10))
# Call main function
main()
g Palindrome counting. Write a Python program stored in a file q3.py to calculate the number of occurrences of palindrome words and palindrome numbers in a sentence. Your program is case-insensitive, meaning that uppercase and lowercase of the same word should be considered the same. The program should print the palindromes sorted alphanumerically with their number of occurrences. Numbers must be printed first, and words must be printed nex
Answer:
The program is as follows:
sentence = input("Sentence: ")
numbers = []; words = []
for word in sentence.split():
if word.lower() == word[::-1].lower():
if word.isdigit() == False:
words.append(word)
else:
numbers.append(int(word))
words.sort(); numbers.sort()
print(numbers); print(words)
Explanation:
This gets input for sentence
sentence = input("Sentence: ")
This initializes two lists; one for numbers, the other for word palindromes
numbers = []; words = []
This iterates through each word of the sentence
for word in sentence.split():
This checks for palindromes
if word.lower() == word[::-1].lower():
If the current element is palindrome;
All word palindromes are added to word palindrome lists
if word.isdigit() == False:
words.append(word)
All number palindromes are added to number palindrome lists
else:
numbers.append(int(word))
This sorts both lists
words.sort(); numbers.sort()
This prints the sorted lists
print(numbers); print(words)
Fictional Corp has a DNS server running within its VPC. It has decided to move one of the application servers to a different VPC. Which of the following is a step that the cloud administrator needs to perform as part of the move?
a. Migrate to an external DNS solution
b. Create a new VPC that will serve DNS needs for multiple other VPCs
c. Discontinue using DNS
d. Remove the DNS entries within the VPC that are no longer relevant
Answer:
Here the correct option is option b Create a new VPC that will serve DNS needs for multiple other VPCs.
Explanation:
Fictional Corp has a DNS server running within its VPC. It has decided to move one of the application servers to a different VPC. It's not possible to maneuver an existing instance to a different subnet or VPC. Instead, you'll manually migrate the instance by creating a new VPC Image from the source instance.
b. Create a new VPC that will serve DNS needs for multiple other VPCs

Modify the solution to PP 11.1 such that it catches and handles the exception if it is thrown. Handle the exception by printing an appropriate message, and then continue processing more strings.
Answer:
Explanation:
The following code is written in Java. After finding the PP 11.1 file online I added the try/catch to the code as requested by the question. The program takes the input from the user, checks it's length, and if it contains more than 20 characters it throws the exception. This exception states that "the string has more than 20 characters" and then continues processing more strings until the user enters "DONE". The program has been tested and the output can be seen in the attached image below. Due to technical difficulties I have added the code as a txt file below.
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;
}
}

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.
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.
