Explanation:
Network Merging and Acquisitions
Environment:
· 400 Windows Servers
· 8000 Windows client devices (laptops running Windows os)
· 40 Linux servers Active Directory Domain Services to provide DNS services to all the hosts, both Windows and Linux.
· Unix servers(Other environment to be merged)
· host resolution they use is BIND
A great challenge of managing a network at a growing company is that of acquisitions. That is, one of the ways a developing company grows is by acquiring other companies. When that acquisition happens, there is usually the require to connect the two networks together.
Connecting two networks environments together is one of those tasks that makes network engineers groan. As networks are not built to any type of agreed-upon norm, what the opposite network will hold is always unpredictable, most probably in a difficult-to-integrate way.
Quick & Dirty IPSEC Tunnel
When an acquisition deal happen, management needs the IT infrastructures connected. The proper way of bringing networks together involves a full audit of the remote network to insure compliance with regulatory obligations, inventorying IP address blocks both public and private and BGP ASNs in use, understanding IGP routing schemes, reviewing WAN provider contracts, itemizing hardware and software in use, purchasing needed equipment, staging infrastructure changes, scheduling maintenance windows, and so on.
Main problems with quick and dirty IPSEC tunnels are
Maintaining network lists manually.
manual maintenance of route injection into the IGP.
Probable single points of failure.
Using SD-WAN As Acquisition Network Glue:
Thinking through SD-WAN technology, quick connectivity option that’s better than a quick and dirty IPSEC tunnel. SD-WAN offers
1. Easily managed redundant plumbing :
SD-WAN forms a mesh of tunnels on top of all available paths. That means that a local circuit outage neither takes down the ability to forward nor needs a network engineer to re-configure IP tunnel endpoints.
2. IGP integration:
When route injection is often available with IPSEC tunnels, it is found that route injection is not terribly reliable, depending on vendor, software version, and a host of other factors. I have not been keen to rely on routes being injected or withdrawn by an IPSEC VPN endpoint.
3. Segment isolation:
An SD-WAN function available from many of SD-WAN vendors is that of segment isolation. You can create virtual network segments that permit intra-segment communication while preventing inter-segment communication. In the case of an acquisition, that functionality seems really helpful.
Segment isolation can also help simplify routing. If you’re facing overlapping, this might help avoid a complex NAT scheme.
4. Service chaining:
Many SD-WAN products shows service chaining. That is, SD-WAN devices tunnel between each other. By seeing the tunnelling ability, it’s possible to drop traffic off when we need.
Drawbacks Of The SD-WAN Approach
A few drawbacks in using SD-WAN as a network merger tool come to mind.
Cost:
The cost of adding a new network segment to an SD-WAN deployment varies by licensing scheme, but is not at all free. Quick and dirty IPSEC tunnels often are free which requires no capital expense to stand up.
Remote hands:
In order to leverage SD-WAN at remote sites, there is a great chance you’ll need remote hands to pull off the device installation. That’s not anything else than deploying SD-WAN in your own network
Perhaps not quick and dirty enough:
The great problem facing around is the long time it takes to stand up dedicated WAN circuits. IPSEC tunnels are often the path of very less resistance to bringing up a private connection between two newly acquainted organizations.
To Conclude:
Using IPSEC tunnels to join networks together what will eventually be part of a unified IT whole isn’t a mature solution in the modern era. SD-WAN looks like a mature solution that do not need require private MPLS circuits to function.
If private MPLS circuits are eventually added to the SD-WAN mix, technology transition is not required. The SD-WAN option can stay in place as-is, using the MPLS circuit being added to the SD-WAN forwarding device as a newly available path. That means the temporary solution can transition into the permanent solution by grace.
SD-WAN can be opted as a way to onboard an acquired network permanently, at the same time retaining the fast time to connect that an IPSEC tunnel offers. For organizations who already have an SD-WAN solution in place, there is nothing to think about. Considering organizations who haven’t invested in SD-WAN so far, this might be an additional driver to do so.

After pushing the power switch of the PC to the ʺonʺ position, Bob, the PC repair person, realizes that the power-on lights found on the monitor and computer case do not light up and nothing displays on the screen. The first thing that Bob does is check the power plugs found on the back of the computer case and monitor. Bobʹs actions best illustrate the use ________ in solving a problem.
1. Professional and technical training
2. Logic3. Communication
4 .Beginnerʹs luck
Answer:
2. Logic
Explanation:
We all know that for the PC to come on, there must be a power input, this means that if the PC does not power on, then there is probably no power input into the PC. It is only logical for Bob to check if the PC is properly connected first when the power-on lights did not come on. People with no technical training should be able to apply this simple logic too.

The OSI is reference/conceptual model and accordingly multiple practical models (such as TCP/IP, AppleTALK, etc) exits. Which fundamental functionalities necessarily needs to considered while implementing any network model?
Answer:
The fundamental functionalities necessarily needs to considered while implementing any network model are (1) Scalability, (2)The quality of service (3) Fault tolerance (4) Security.
Explanation:
Solution:
Network must help a wide area of applications and administrations, just just as work over various sorts of links and devices that make up the physical infrastructure. The term network refers to the innovations that help the infrastructure and the customized administrations and rules, or protocols, that move messages over the network.
The following are some fundamental functionalities necessarily needs to considered while implementing any network model which is stated below:
(1) Scalability :
A huge number of users and service providers connect with the Internet every week. All together for the Internet to help this fast measure of development, it must be scalable.
A scalable network can extend rapidly to help new clients and applications without influencing the performance of the administration being conveyed to existing clients.
(2)Quality of Service :
Networks must provide predictable, quantifiable, and, now and again, ensured administrations.
Networks also need mechanisms to carry on congested network traffic. Network bandwidth is the estimate of the data-transfer size of the network. As such, what amount of data can be transmitted inside a particular measure of time? Network data transfer capacity is estimated in the quantity of bits that can be transmitted in a solitary second, or bits every second (bps).
(3) Fault Tolerance :
The Internet is consistently accessible to the a huge number of users who depend on it. This requires a network design that is worked to be fault tolerant.
A fault-tolerant network is one that constrains the impact of a failure, with the goal that the least number of devices are influenced by it. It is likewise worked in a manner that empowers fast recuperation when such a failure happens.
Faults-tolerant networks rely upon various ways between the source and destination of a message. On the off chance that one way comes up short, the messages can be immediately sent over an alternate connection.
(4) Security:
The Internet has advanced from a firmly controlled inter network of instructive and government associations to a generally open methods for transmission of business and individual interchanges.
Subsequently, the security necessities of the network have changed. The network infrastructure, the system administrations, and the information contained on arrange appended gadgets are vital individual and business resources. Bargaining the respectability of these benefits could have genuine outcomes.

Assume the following variable definition appears in a program:
double number = 12.3456;
Write a cout statement that uses the setprecision manipulator and the fixed manipulator to display the number variable rounded to 2 digits after the decimal point. (Assume that the program includes the necessary header file for the manipulators.)
Answer:
cout << setprecision(2)<< fixed << number;
Explanation:
The above statement returns 12.35 as output
Though, the statement can be split to multiple statements; but the question requires the use of a cout statement.
The statement starts by setting precision to 2 using setprecision(2)
This is immediately followed by the fixed manipulator;
The essence of the fixed manipulator is to ensure that the number returns 2 digits after the decimal point;
Using only setprecision(2) in the cout statement will on return the 2 digits (12) before the decimal point.
The fixed manipulator is then followed by the variable to be printed.
See code snippet below
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
// Initializing the double value
double number = 12.3456;
//Print result
cout << setprecision(2)<< fixed << number;
return 0;
}

In a horse race, the odds that Romance will win are listed as 2 : 3 and that Downhill will win are
1:2. What odds should be given for the event that either Romance or Downhill wins? (3 mks)
QUESTION FOUR
Answer:
The odds for the event that either Romance or Downhill wins is 11/4
Explanation:
The odds that Romance will win is 2: 3
The odds that Downhill will win is 1:2
[tex]P(event) = \frac{Odd(event)}{1 + Odd(event)}[/tex]
Where P(event) = Probability that an event occurs
Odd(event) = The odds that an event occurs
Calculate the Probability that Romance wins, P(R):
[tex]P(R) = \frac{2/3}{2/3 + 1} \\P(R) = 2/5[/tex]
Calculate the probability that Downhill wins, P(D):
[tex]P(D) = \frac{1/2}{1/2 + 1} \\P(D) = 1/3[/tex]
Calculate the Probability that either Romance or Downhill wins, P(R or D):
P(R or D) = P(R) + P(D)
P(R or D) = 2/5 + 1/3
P(R or D) = 11/15
[tex]P(R or D) = \frac{Odd(R or D)}{1 + Odd(R or D)} \\\\11/15 = \frac{Odd(R or D)}{1 + Odd(R or D)}\\[/tex]
[tex]\frac{11}{15} + \frac{11}{15}[ Odd(R or D)] = Odd(R or D)\\\\\frac{4}{15}[ Odd(R or D)] = \frac{11}{15}\\\\\\Odd(R or D) = \frac{11}{15} * \frac{15}{4}\\\\Odd(R or D) = 11/4[/tex]

Suppose two computers (A & B) are directly connected through Ethernet cable. A is sending data to B, Sketch the waveform produced by A when “$” is sent. Also mention the OSI layer that is responsible for this.
Answer:
Physical / Data link layer
Explanation:
If two computers (A & B) are directly connected through Ethernet cable. A is sending data to B, the data would be transmitted if the network is clear but if the network is not clear, the transmission would wait until the network is clear.
The Open Systems Interconnection model (OSI model) has seven layers each with its own function.
The physical layer is the first layer responsible for data transmission over a physical link. The data packets are converted to signals over a transmission media like ethernet cable.
The data link layer is the second layer in the OSI layer responsible for transmission of data packets between nodes in a network. It also provides a way of detecting errors and correcting this errors produced as a result of data transmission.

For each of the descriptions below, perform the following tasks:
i. Identify the degree and cardinalities of the relationship.
ii. Express the relationships in each description graphically with an E-R diagram.
a. A book is identified by its ISBN number, and it has a title, a price, and a date of publication. It is published by a publisher, which has its own ID number and a name. Each book has exactly one publisher, but one publisher typically publishes multiple books over time.
b. A book is written by one or multiple authors. Each author is identified by an author number and has a name and date of birth. Each author has either one or multiple books; in addition, occasionally data are needed regarding prospective authors who have not yet published any books.
c. In the context specified in 2a and 2b, better information is needed regarding the relationship between a book and its authors. Specifically, it is important to record the percentage of the royalties that belongs to a specific author, whether or not a specific author is a lead author of the book, and each author's position in the sequence of the book's authors.
d. A book can be part of a series, which is also identified as a book and has its own ISBN number. One book can belong to several sets, and a set consists of at least one but potentially many books.
e. A piano manufacturer wants to keep track of all the pianos it makes individually. Each piano has an identifying serial number and a manufacturing completion date. Each instrument represents exactly one piano model, all of which have an identification number and a name. In addition, the company wants to maintain information about the designer of the model. Overtime, the company often manufactures thousands of pianos of a certain model, and the model design is specified before any single piano exists.
f. A piano manufacturer (see 2e) employs piano technicians who are responsible for inspecting the instruments before they are shipped to the customers. Each piano is inspected by at least two technicians (identified by their employee number). For each separate inspection, the company needs to record its date and a quality evaluation grade.
g. The piano technicians (see 2f) have a hierarchy of reporting relationships: Some of them have supervisory
responsibilities in addition to their inspection role and have multiple other technicians report to them. The supervisors themselves report to the chief technician of the company.
h. A vendor builds multiple types of tablet computers. Each has a type identification number and a name. The key
specifications for each type include amount of storage space and display type. The company uses multiple processor types, exactly one of which is used for a specific tablet computer type; obviously, the same processor can be used in multiple types of tablets. Each processor has a manufacturer and a manufacturer's unique code that identifies it.
i. Each individual tablet computer manufactured by the vendor (see 2h) is identified by the type identification number and a serial number that is unique within the type identification. The vendor wants to maintain information about when each tablet is shipped to a customer.
j. Each of the tablet computer types (see 2h) has a specific operating system. Each technician the company employs is certified to assemble a specific tablet type—operating system combination. The validity of a certification starts on the day the employee passes a certification examination for the combination, and the certification is valid for a specific period of time that varies depending on tablet type—operating system combination.

(a)
(I) The level of the given relationship is 2 i.e it is a parallel connection among Book and Publisher. It is a one to numerous relationship from distributer to book in light of the fact that a distributer can distribute any number of books however a book will have only one publisher,so the cardinality will be 1 to 1..* (one to many)
(b)
(i) The degree of the given relationship is 2 i.e it is a binary relationship between Author and Book. It is a many to many relationship from Book to Author a book can be written by one or more authors and an author can write more than one book, so the cardinality will be 1..* to 1..* (many to many)
(c)
(i) As mentioned in part (b), the degree of given relation is 2 and cardinality is many to many (1..* to 1..*)
(d)
(i) The degree of the given relationship is 1 i.e unary relationship. It is a many to many relationship because one book can belong to any sets and a set can have any number of books, so cardinality is 1..* to 1..* (many to many)

Explanation:
APEVX
The label of the next version of the document can probably be ProjectReport_v2.docx. The correct option is D.
What is a document?A document's purpose is to enable the transmission of information from its author to its readers.
It is the author's responsibility to design the document so that the information contained within it can be interpreted correctly and efficiently. To accomplish this, the author can employ a variety of stylistic tools.
Documentation can be of two main types namely, products and processes. Product documentation describes the product under development and provides instructions on how to use it.
A document file name is the name given to a document's electronic file copy.
The file name of the document does not have to be the same as the name of the document itself. In fact, you can use the shortest possible version of the name.
As the document here is second version of the previous one, so its name should be ProjectReport_v2.docx.
Thus, the correct option is D.

Write a method that computes the sum of the digits in an integer. Use the following method header: public static int sumDigits(long n) For example, sumDigits(234) returns 9 the result of 2 3 4. (Hint: Use the % operator to extract digits, and the / operator to remove the extracted digit. For instance, to extract 4 from 234, use 234 % 10, which is 4. To remove 4 from 234, use 234 / 10, which is 23. Use a loop to repeatedly extract and remove the digit until all the digits are extracted.
Answer:
The java program for the given scenario is shown below.
import java.util.*;
import java.lang.*;
public class Test
{
//variables to hold the number, digits and sum of the digits
//variable to hold number is assigned any random value
static long num=123;
static int sum=0;
static int digit;
static int s;
//method to add digits of a number
public static int sumDigits(long n)
{ do
{
digit=(int) (n%10);
sum=sum+digit;
n=n/10;
}while(n>0);
return sum;
}
public static void main(String[] args) {
s = sumDigits(num);
System.out.println("The sum of the digits of "+num+ " is "+s); }
}
OUTPUT
The sum of the digits of 123 is 6
Explanation:
1. The variables to hold the number is declared as long and initialized.
2. The variables to store the digits of the number and the sum of the digits are declared as integer. The variable, sum, is initialized to 0.
3. The method, sumDigits(), is defined which takes a long parameter and returns an integer value. The method takes the number as a parameter and returns the sum of its digits.
4. Inside method, sumDigits(), inside the do-while loop, the sum of the digits of the parameter is computed.
5. Inside main(), the method, sumDigits(), is called. The integer value returned by this method is stored in another integer variable, s.
6. The sum of the digits is then displayed to the console.
7. All the variables are declared outside main() and at the class level and hence declared static. The method, sumDigits(), is also declared static since it is to be called inside main().
8. In java, the whole code is written inside a class since java is a purely object-oriented language.
9. In this program, object of the class is not created since only a single class is involved having main() method.
10. The program can be tested for any value of the variable, num.
11. The file is saved as Test.java, where Test is the name of the class having main() method.
What color model should Joe use if he will be using an offset printing press?
Answer:
The color model used for an offset printing press should involve cyan, magenta, yellow and black. The combination of this creates a black color.
Offset printing doesn’t involve the direct contact of the ink with the paper. The ink usually comes in contact first with a rubber cylinder after which the cylinder makes the necessary imprints on the paper.
The goal for me is that I need to identify the objects needed for the UNO card game and the actions that those objects perform, rather than how the objects are suppose to actually be represented. Write a document that includes an ADT (abstract data type) for each object needed in my program. This is a partial ADT for the UnoCard class.
//get the color of the car
+getColor(): String
//set the color of the card
+setColor(color : String):void
//get the value of the card
+getValue(): int
//set the value of the card
+getValue(val : int): void
//return true if card has same value or
//same color as the card
//return false otherwise
+isMatch(card: UnoCard): boolean
The standard UNO card must be able to report both its color and value, and, when given another card, tell whether or not it is a "match.
Answer:
Explanation:
//Java program
class UnoCard{
private String color;
private int value;
public UnoCard(String color , int val) {
this.color = color;
value = val;
}
public String getColor() {
return color;
}
//set the color of the card
public void setColor(String color ) {
this.color = color;
}
//get the value of the card
public int getValue() {
return value;
}
//set the value of the card
public void setValue(int val) {
value = val;
}
//return true if card has same value or
//same color as the card
//return false otherwise
public boolean isMatch(UnoCard card) {
return (this.value==card.value)||(this.color==card.color);
}
}
public class Card {
public static void main(String args[]) {
UnoCard card1 = new UnoCard("Red",10);
UnoCard card2 = new UnoCard("Green",10);
UnoCard card3 = new UnoCard("Blue",15);
if(card1.isMatch(card2))System.out.println("Match");
else System.out.println("No Match");
if(card2.isMatch(card3))System.out.println("Match");
else System.out.println("No Match");
}

2-3 Calculating the Body Mass Index (BMI). (Programming Exercise 2.14) Body Mass Index is a measure of health based on your weight. It can be calculated by taking your weight in kilograms and dividing by the square of your height in meters. Write a program that prompts the user to enter a weight in pounds and height in inches and displays the BMI. Note: One pound is 0.45359237 kilograms and one inch is 0.0254 meters. Hint: Convert the pounds entered into kilograms also convert the height in inches into meters Example: If you entered in pounds your weight as 95.5 and your height as 50 inches then the calculated BMI is 26.8573 FYI: BMI < 18.5 is underweight BMI >
Answer:
weight = float(input("Enter your weight in pounds: "))
height = float(input("Enter your height in inches: "))
weight = weight * 0.45359237
height = height * 0.0254
bmi = weight / (height * height)
print("Your BMI is: %.4f" % bmi)
Explanation:
*The code is written in Python.
Ask the user to enter weight in pounds and height in inches
Convert the weight into kilograms and height into meters using given conversion rates
Calculate the BMI using given formula
Print the BMI
Richard Palm is the accounting clerk of Olive Limited. He uses the source documents such as purchase orders, sales invoices and suppliers’ invoices to prepare journal vouchers for general ledger entries. Each day he posts the journal vouchers to the general ledger and the related subsidiary ledgers. At the end of each month, he reconciles the subsidiary accounts to their control accounts in the general ledger to ensure they balance.
Discuss the internal control weaknesses and risks associated with the above process. (maximum 300 words)
Answer:
Lack of segregation of duties
Explanation:
Internal Controls are set of rules and guidelines that are followed to ensure effectiveness of business operations. The main risk in the business is weak internal controls. There are some organizations with strong internal controls but implementation of such controls is a challenge for organizations. There are human errors, IT security risks, fraud and compliance risk.
The risks associated with Olive limited is that there is no segregation of duties, Richard Palm is preparing journal vouchers, posts the journal vouchers and reconciles the balance himself. If he makes an error in recording a transaction there is no one who reviews his work and can identify an error. Also if Richard is involved in a fraud and collaborates with purchase department or sales department staff, he can pass a transaction without any supervision.

System.out.print(str3+" ");
System.out.println(str2);
}
}
else if(str2.compareTo(str1) < 0 && str2.compareTo(str3) < 0){
System.out.print(str2+" ");
if(str1.compareTo(str3) < 0){
System.out.print(str1+" ");
System.out.println(str3);
}
else {
System.out.print(str3+" ");
System.out.println(str1);
}
}
else{
System.out.print(str3+" ");
if(str1.compareTo(str2) < 0){
System.out.print(str1+" ");
System.out.println(str2);
}
else {
System.out.print(str2+" ");
System.out.println(str1);
}
}
}
}
EXPLANATION:
Okay, we are given that a program should be written which will make user to enter three cities namely Atlanta, Chicago and Los Angeles (which should be done in ascending alphabetical order).
So, we will be writting the code or program with a programming language known as JAVA(JUST ANOTHER VIRTUAL ACCELERATOR).
We will make use of java to write this program because Java can be used in Loading code, verifying codes and executing codes on a single or multiple servers.
The code or program can be seen in the attached file/document. Kindly check it.
