The U.S. government has put in place IPv6-compliance mandates to help with the IPv4-to-IPv6 transition. Such mandates require government agencies to have their websites, email and other services available over IPv6.
Let’s consider that you’ve been appointed as the IPv6 transition manager at a relatively small branch of a government agency (e.g., a branch of the Social Security agency in a medium-size town). Your main responsibility is to produce a plan with a timetable for achieving compliance with the IPv6 mandate. The plan should specify the guidelines, solutions, and technologies for supporting IPv6 throughout the agency branch. The plan should include the following, among other things:
Summary of the applicable government IPv6 mandate
Brief description of the networking facility at the branch (LANs, servers, routers, etc.)
Summary of the main IPv6-related RFCs that pertain to the IPv6 support
Cooperation with ISPs and equipment vendors to implement IPv6 support
Summary of the solutions and technologies to be employed in implementing IPv6 (e.g., dual-stack, tunneling, translation)
Timetable for completion of IPv6 transition
Plan for testing the IPv6 compliance in expectation of an audit by the government
The deliverable is a report (in Word) of 6 to 10 pages, excluding the name and biblio pages, with 3 to 5 solid references (APA format), at least. The use of drawings and other graphics is highly recommended.
Answer:
The U.S. Government has put in place an IPv6 mandate that comes into affect on September 30th. That new mandate requires all government agencies to have their public facing websites and email services available over IPv6.
At this point, it’s not likely that every government website will meet the deadline, though a large number of them will. Christine Schweickert, senior engagement manager for public sector at Akamai, told EnterpriseNetworkingPlanet that she expects over 1,800 U.S Government websites will be on IPv6 by the mandate deadline.
From an Akamai perspective, the company has a large number of U.S. Government customers that it is enabling for IPv6 with dual-stack servers. In a dual-stack implementation, a site is available natively over both IPv4 and IPv6. Akamai’s Content Delivery Network has a mapping technology that optimizes traffic around the Internet. Getting the government websites to run on IPv6 is just a matter of putting the site configuration on the Akamai dual-stack server maps.
“So if a request comes in to a government website from an IPv6 client, we will go ahead and route them to the best performing Akamai Edge server that can speak IPv6 back to that request,” Schweickert explained.
Another approach that some network administrators have tried for IPv6 support has been to tunnel the IPv6 traffic over an IPv4 network, or vice-versa. In Schweickert’s view, that’s not an ideal solution as it tends to break things.“When you’re tunneling, you’re routing through IPv4 packets and that’s not in the spirit that we have to operate in globally,” Schweickert said.
In contrast, Schweickert noted that with dual-stack, the server will respond to IPv4 requests with IPv4 content and to IPv6 requests with IPv6 content. “If you’re using tunneling, you’re really just doing a workaround,” Schweickert said.
To make it even easier for the U.S. Government websites, Akamai isn’t actually charging more money for the dual-stack service either. Schweickert noted that the dual-stack capability is a feature that is already part of the delivery service that Akamai is providing to its U.S Government customers.
David Helms, Vice President, Cyber Security Center of Excellence at Salient Federal Solutions is among those that are backers of the Akamai approach to meeting the September 30th IPv6 mandate. In his view, it’s all about enabling interesting services and locations over IPv6 in order to spur adoption.

H0: Protype design has at most 37mpg vs. HA: prototype design has greater than 37mpg. If H0 is rejected, the action will be move the protype deisgn to prpduction. What kind of test is required
Answer:
A one-tailed test with upper reject region
Explanation:
H0 : μ ≤ 37
H1 : μ > 37
This is a right tailed tailed test as indicated by the greater than symbol on the hypothesis defined. Hence, the critical region will lie to the right of the area under the curve.
Critical region which lies to the right of the curve is called the upper rejection region.
Rejecting the Null, H0 means that ; the value of the test statistic exceeds the critical value;
When the hypothesis is declared with the less than sign, rejection region lies to the left or lower region.
While a two tailed test has rejection region shares between each tail.
The Marietta Country Club has asked you to write a program to gather, then display the results of the golf tournament played at the end of March. The Club president Mr. Martin has asked you to write two programs.
The first program will input each player's first name, last name, handicap and golf score and then save these records in a file named golf.txt (each record will have a field for the first name, last name, handicap and golf score).
The second program will read the records from the golf.txt file and display them with appropriate headings above the data being displayed.
If the score is = Par, then display 'Made Par'
If the score is < Par, then display 'Under Par'
If the score is > Par, then display 'Over Par'
There are 16 players in the tournament. Par for the course is 80. The data is as follows:
Andrew Marks 11.2 72
Betty Franks 12.8 89
Connie William 14.6 92
Donny Ventura 9.9 78
Ernie Turner 10.1 81
Fred Smythe 8.1 75
Greg Tucker 7.2 72
Henry Zebulon 8.3 83
Ian Fleming 4.2 72
Jan Holden 7.7 84
Kit Possum 7.9 79
Landy Bern 10.3 93
Mona Docker 11.3 98
Kevin Niles 7.1 80
Pam Stiles 10.9 87
Russ Hunt 5.6 73
Answer:
Explanation:
The following program is written in Python. It creates two functions, one for writting the players and their scores to the file, and another function for reading the file and outputting whether or not they made Par. The functions can be called as many times that you want and the writeFile function allows for 16 inputs to be made when called. A test case has been provided with all of the players mentioned in the question. The output can be seen in the attached image below.
def writeFile():
file = open('output.txt', 'w')
for x in range(16):
firstName = input("Enter First Name:")
lastName = input("Enter Last Name:")
handicap = input("Handicap:")
score = input("Score:")
file.write(str(firstName) + " " + str(lastName) + " " + str(handicap) + " " + str(score) + "\n")
file.close()
def readFile():
file = open('output.txt', 'r')
for line in file:
lineArray = line.split(" ")
if int(lineArray[-1]) < 80:
print(str(lineArray[0]) + " " + str(lineArray[1]) + " Under Par" )
elif int(lineArray[-1]) == 80:
print(str(lineArray[0]) + " " + str(lineArray[1]) + " Made Par")
else:
print(str(lineArray[0]) + " " + str(lineArray[1]) + " Over Par")
file.close()
writeFile()

Given the snippet of code: int x = 5; int bar(int j) { int *k = 0, m = 5; k = &m; return (j+m); } void main(void) { static int i =0; i++; i = bar(i) + x; } Which variables obtain their memory from the stack? A. iB. jC. kD. mE. x
Answer:
Variables j , k , m will be stored in the stack.
Explanation:
Variable x will not be in stack as is it a global variable.
Variable i will not be in stack as is it a static variable.
Variable j will be in stack as is it a local variable in the function.
Variable m will be in stack as is it a local variable in the function.
Variable k , a pointer will be in stack as it is in the function bar locally.
Write a program using a dictionary that reads in a single positive digit number [0 - 9] from the user at the keyboard. Your program will then be able to look up the digit key in the dictionary and print the digit value spelled out. If the user types in a number that is either more than one digit, negative, or a non int value, re-prompt the user for valid input. First, before demonstrating your test cases, print out a display copy of the key:value pairs in your dictionary in sorted order. Deliverable: yournameLab4.py Your source code solution and a copy of the run pasted into your source submission file. Be sure to comment out your run so that your .py file will still run in the grader test bed. Validate user input is a single positive digit [0 - 9].
Answer:
The program in Python is as follows:
dict = {0:"Zero",1:"One",2:"Two",3:"Three",4:"Four",5:"Five",6:"Six",7:"Seven",8:"Eight",9:"Nine"}
num = input("Number: ")
while(num.isdigit() == False or int(num)<0 or int(num)>9):
num = input("Number: ")
print(dict)
print(dict[int(num)])
Explanation:
#This initializes the dictionary
dict = {0:"Zero",1:"One",2:"Two",3:"Three",4:"Four",5:"Five",6:"Six",7:"Seven",8:"Eight",9:"Nine"}
#This gets input from the user
num = input("Number: ")
#This loop is repeated until the user enters a valid input
while(num.isdigit() == False or int(num)<0 or int(num)>9):
num = input("Number: ")
#This prints the dictionary
print(dict)
#This prints the value of the key
print(dict[int(num)])

Which tool, first introduced in Windows Server 2008 but remains in Windows Server 2019, provides one location to set up, deploy, and manage servers and server roles
Answer:
Server Manager
Explanation:
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM, Windows Server 2008, Windows Server 2009, etc.
Windows Server 2008 is a Microsoft Windows Server operating system and released to the general public on the 27th of February, 2008, as part of the Windows NT family.
Server Manager is a tool that was first introduced in Windows Server 2008 (OS) but remains in Windows Server 2019 (OS). It was designed and developed by Microsoft to provide end users with one location to set up, deploy, and manage servers and server roles.
On the 14th of January, 2020, Microsoft stopped providing online technical content update, free support options, non-security and free security updates on-premises for Windows Server 2008 and Windows Server 2008 R2, as they have reached the end of their support lifecycle.

This increased accesibility is crucial for companies that have employees that move from place to place solving problems and solves many of the problems with on-site systems.
Write a function, named FileLineCount(), that returns an integer and accepts a string. Pass the function the file name. It should then use a while loop to return the number of lines in a file. Hint: The function will be reading the file you just created above. g
Answer:
Explanation:
The following code is written in Python. It is a function that accepts a file string and uses that string to read the file in that location. Then it uses a while loop that keeps going until there are no more lines in the file. Each iteration it adds 1 to the count variables. Finally, it prints the count variable which contains the total number of lines in the file. The code has been tested and the output can be seen in the attached image below.
def countLines(file):
file = open(file, 'r')
count = 0
while file.readline():
count += 1
print(str(count) + " total lines")

Answer:
Each node on the network has an addres which is called the ip address of which data is sent as IP packets. when the client sends its TCP connection request, the network layer puts the request in a number of packets and transmits each of them to the server.
2.13 LAB: Branches: Leap Year
A year in the modern Gregorian Calendar consists of 365 days. In reality the earth takes longer to rotate around the sun. To account for the
difference in time every 4 years a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The
requirements for a given year to be a leap year are:
1) The year must be divisible by 4
2) If the year is a century year (1700 1800. etc.), the year must be evenly divisible by 400
Some example leap years are 600712 and 2016
Wirte a program that takes n a year and determines whether that year is a leap year.
Exif the inputs
1712
Answer:
The program in Python is as follows:
year = int(input("Enter a year: "))
print(year,end=" ")
if year % 4 == 0:
if year % 100 == 0:
if year % 400 == 0: print("is a leap year")
else: print("is not a leap year")
else: print("is a leap year")
else: print("is not a leap year")
Explanation:
This gets input for year
year = int(input("Enter a year: "))
This prints year, followed by a blank
print(year,end=" ")
If year is divisible by 4
if year % 4 == 0:
If yes, check if year is divisible by 100
if year % 100 == 0:
If yes, check if year is divisible by 400; print leap year if true
if year % 400 == 0: print("is a leap year")
print not leap year if year is not divisible by 400
else: print("is not a leap year")
print leap year if year is not divisible by 100
else: print("is a leap year")
print leap year if year is not divisible by 4
else: print("is not a leap year")
Answer:
def is_leap_year(user_year):
if(user_year % 400 == 0):
return True
elif user_year % 100 == 0:
return False
elif user_year%4 == 0:
return True
else:
return False
if __name__ == '__main__':

Answer:
10000
Explanation:
Discuss and illustrate the operation of the AND, OR, XOR and NOT gate of a Boolean logical operation giving examples of possible outcomes of 0 and 1 as input in a truth set tabular format.
Answer:
Use below picture as a starting point.
IN C++
A. Create an abstract base class called Currency with two integer attributes, both of which are non-public. The int attributes will represent whole part (or currency note value) and fractional part (or currency coin value) such that 100 fractional parts equals 1 whole part.
B. Create one derived class - Money - with two additional non-public string attributes which will contain the name of the currency note (Dollar) and currency coin (Cent) respectively. DO NOT add these attributes to the base Currency class.
C. In your base Currency class, add public class (C++ students are allowed to use friend methods as long as a corresponding class method is defined as well) methods for the following, where appropriate:
Default Construction (i.e. no parameters passed)
Construction based on parameters for all attributes - create logical objects only, i.e. no negative value objects allowed
Copy Constructor and/or Assignment, as applicable to your programming language of choice
Destructor, as applicable to your programming language of choice
Setters and Getters for all attributes
Adding two objects of the same currency
Subtracting one object from another object of the same currency - the result should be logical, i.e. negative results are not allowed
Comparing two objects of the same currency for equality/inequality
Comparing two objects of the same currency to identify which object is larger or smaller
Print method to print details of a currency object
All of the above should be instance methods and not static.
The add and subtract as specified should manipulate the object on which they are invoked. It is allowed to have overloaded methods that create ane return new objects.
D. In your derived Money class, add new methods or override inherited methods as necessary, taking care that code should not be duplicated or duplication minimized. Think modular and reusable code.
E. Remember -
Do not define methods that take any decimal values as input in either the base or derived classes.
Only the print method(s) in the classes should print anything to console.
Throw String (or equivalent) exceptions from within the classes to ensure that invalid objects cannot be created.
F. In your main:
Declare a primitive array of 5 Currency references (for C++ programmers, array of 5 Currency pointers).
Ask the user for 5 decimal numbers to be input - for each of the inputs you will create one Money object to be stored in the array.
Once the array is filled, perform the following five operations:
Print the contents of the array of objects created in long form, i.e. if the user entered "2.85" for the first value, it should be printed as "2 Dollar 85 Cent".
Add the first Money object to the second and print the resulting value in long form as above.
Subtract the first Money object from the third and print the resulting value in long form as above.
Compare the first Money object to the fourth and print whether both objects are equal or not using long form for object values.
Compare the first Money object to the fifth and print which object value is greater than the other object value in long form.
All operations in the main should be performed on Currency objects demonstrating polymorphism.
Remember to handle exceptions appropriately.
There is no sample output - you are allowed to provide user interactivity as you see fit.

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

Excel is very efficient to use, especially when you have to calculate your data, it's not hard to calculate the computer itself calculates it for you.they are also disadvantages of excel which is;
some users might get a little bit problem when you send Microsoft Excel, here is one sometimes the spreadsheet are difficult to share internally.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.

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.
Scenario You are a network engineer and it is your first day working with ASU and you have been given the job of creating a network for the IT program. You are given the following three tasks to complete. 1. Configure IP addressing settings on network devices. 2. Perform basic device configuration tasks on a router. 3. Verify Layer 3 connectivity via a routing protocol. 4. Setup some access control lists.

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.
