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

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.

1) Declare an ArrayList named numberList that stores objects of Integer type. Write a loop to assign first 11 elements values: 1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024. Do not use Math.pow method. Assign first element value 1. Determine each next element from the previous one in the number List. Print number List by using for-each loop.
Answer:
Explanation:
The following is written in Java and uses a for loop to add 10 elements to the ArrayList since the first element is manually added as 1. Then it calculates each element by multiplying the previous element (saved in count) by 2. The program works perfectly and without bugs. A test output can be seen in the attached image below.
import java.util.ArrayList;
class Brainly {
public static void main(String[] args) {
ArrayList<Integer> numberList = new ArrayList<>();
numberList.add(0, 1);
int count = 1;
for (int i = 1; i < 11; i++) {
numberList.add(i, (count * 2));
count = count * 2;
}
for (Integer i : numberList) {
System.out.println(i);
}
}
}
Write a program that defines an array of integers and a pointer to an integer. Make the pointer point to the beginning of the array. Then, fill the array with values using the pointer (Note: Do NOT use the array name.). Enhance the program by prompting the user for the values, again using the pointer, not the array name. Use pointer subscript notation to reference the values in the array.
Answer:
#include<iostream>
using namespace std;
int main()
{
int a[20],n;
int *p;
cout<<"\n enter how many values do you want to enter:";
cin>>n;
for(int i=0;i<n;i++)
{
cout<<"\n Enter the "<<i+1 <<"th value :";
cin>>*(p+i);
//reading the values into the array using pointer
}
cout<<"\n The values in the array using pointer is:\n";
for(int i=0;i<n;i++)
{
cout<<"\n (p+"<<i<<"): "<<*(p+i);
//here we can use both *(p+i) or p[i] both are pointer subscript notations
}
}

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.

Answer:
a. it designs its own applications but doesn't customize the operating system.
Explanation:
Cloud computing can be defined as a type of computing that requires shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.
Generally, cloud computing offers individuals and businesses a fast, effective and efficient way of providing services.
Cloud computing comprises of three (3) service models and these are;
1. Infrastructure as a Service (IaaS).
2. Software as a Service (SaaS).
3. Platform as a Service (PaaS).
Platform as a Service (PaaS) refers to a type of cloud computing model in which a service provider makes available a platform that allow users (software developers) to build code (develop), run, store information in a database and manage applications over the internet.
The main purpose of a Platform as a Service (PaaS) is to provide an enabling environment for software developers to code without having to build and maintain complex infrastructure needed for the development, storage and launching of their software applications.
Simply stated, PaaS makes provision for all of the software and hardware tools required for all the stages associated with application development over the internet (web browser).
Some of the advantages of Platform as a Service (PaaS) is that, it avails software developers with enough convenience as well as simplicity, service availability, ease of licensing and reduced costs for the development of software applications.
Basically, platform as a Service (PaaS) providers (vendors) usually provide their clients (software developers) with server and data storage, operating system, data center, networking resources, etc., while the software developers design, deploy and manage their software applications.
Hence, a business should choose the platform as a service (PaaS) cloud model when it designs its own applications but doesn't customize the operating system.
Implementing HTML best practices and writing code to match the original intentions of each element is known as __________ HTML. standard attribute-based industry semantic
Answer:

Explanation:
The description provided is describing the practice known as semantic HTML. This is basically code that provides both the user and the developer a description on what the code was originally supposed to do. For example, a method that calculates the total cost of a set of prices could be called calculateTotal(). By doing so you are describing the intention of the method clearly so that the individual using the method does not need to look at anything else to know what it does.
Implementing HTML best practices and writing code to match the original intentions of each element is known as __________ HTML.
SemanticBased on the knowledge of semantics HTML which is a programming language used to write codes for the building blocks of any website, it gives the user and programmer the details of what the code is supposed to perform.

A small e-commerce company uses a series of Robotic Process Automation solutions to manage the backup of data from individual workstations to an on-premise server. However, the company is opening another office and would like to more easily share data between locations, along with better protecting the data from loss.
Which technology could be combined with their current automated processes to do this?
Answer:
Cloud.
Explanation:
Cloud computing can be defined as a form of data computing which requires the use of shared computing resources such as cloud storage (data storage), servers, computer power, and software over the internet rather than local servers and hard drives.
Generally, cloud computing offer individuals and businesses a fast, secured, effective and efficient way of providing services over the internet.
Basically, cloud computing comprises three (3) service models and these include;
1. Platform as a Service (PaaS).
2. Software as a Service (SaaS).
3. Infrastructure as a Service (IaaS).
Additionally, the two (2) main characteristics of cloud computing are;
I. Measured service: it allows cloud service providers to monitor and measure the level of service used by various clients with respect to subscriptions.
II. Resource pooling: this allows cloud service providers to serve multiple customers or clients with services that are scalable and provisional.
For example, the provisioning of On-demand computing resources such as storage, network, virtual machines (VMs), etc., so as to enable the end users install various software applications, database and servers.
Hence, the technology that could be combined by the small e-commerce company with its current automated processes is cloud storage.
There are different tools used in data sharing. The technology that could be combined with their current automated processes to do this is blockchain.
Blockchain is known to use different kinds of distributed ledger that is often shared across networked devices. Through this, people on the network can share files and values securely and even on a peer-to-peer basis. This is no need any middlemen.

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

What does the AVERAGE function calculate? the total sum of a list of values the arithmetic mean of a list of values the total number of values in a list the percentage of values in a list
Answer:
B) the arithmetic mean of a list of values
Explanation:
on Edge
The Average function calculates the arithmetic mean of a list of values. Therefore, option B is the correct option.
What is the average?In its most general definition, an average can be considered as the representative number or figure from the whole list. The average of a list containing multiple values is obtained by adding all the values and dividing them up by the total number of values.
The ultimate objective of calculating the average is to discover the value that represents the whole list. Average is also known as mean, and it works as a central value in the list, which is comprehensive in nature. It works as an approximate or rough estimate, which helps us in making decisions in daily life.
Thus, the average function calculates the arithmetic mean of a list of values. Therefore, option B is the correct option.

When a Select Case statement executes, the value of the test expression is compared with the values that follow each of the _______ keywords.
Answer:
Case
Explanation:
In Computer programming, a variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited.
Basically, variable stores information which is passed from the location of the method call directly to the method that is called by the program.
For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function. Therefore, when you create variables in a function, you can can set the values for their parameters.
A Select Case statement can be defined as a conditional statement that avails software developers or programmers the ability to test a variable by comparing it with a list of values.
In a Select Case statement, each variable is referred to as a Case.
Generally, when a Select Case statement executes, the value of the test expression is compared with the values that follow each of the Case keywords.

Write a program that asks a user to enter a date in month day year format (for example 10 12 2016) and displays the day of the week for that date, in this case, Wednesday.
Answer and Explanation:
Using javascript:
function dayof_theweek(){
var TodayDate = window. prompt("enter today's date in the format 'year, month, day' ");
var Datenow=new date(TodayDate);
var Dayofweek=Datenow.getday();
var Days=["monday","Tuesday", "Wednesday", "Thursday", "Friday", "Saturday", "Sunday"];
if(Dayofweek==indexOf(Days[Dayofweek]))
{
document.createTextnode(Days[Dayofweek]);
}
}
The program above uses a date object which uses the method getday to get the day of the week(get day returns an integer from 0 to 6).we then use a comparison operator == to test the condition that returned value Dayoftheweek is same with the index of the array Days and then print to a html document. The program may need improvements such as the fact that errors may arise when proper input isn't given, and therefore must be handled.
