Answer:

ABC Company

The action to take is to:

Delete the .(root) zone from the DNS2.  Then configure conditional forwarding on the DNS2 server.  If this is not done, the users will be unable to access the internet.

Explanation:

DNS forwarding enables DNS queries to be forwarded to a designated server, say DNS2, for resolution according to the DNS domain name.  This stops the initial server, DNS1, that was contacted by the client from handling the query, thereby improving the network's performance and resilience and enabling the users to be connected to the DNS2 in order to access the internet.

Answer:

Incremental development in software engineering is a process methodology that emphasizes the virtue of taking small steps toward the goal.

Explanation:

Rather than delaying feedback until final delivery when time and resources have already been spent, incremental development ensures that teams can use feedback to make changes early and often.

The main importance of the Incremental model is that it divides the software development into submodules and each submodule is developed by following the software development life cycle process SDLC like Analysis, Design, Code, and Test.

Answer:

 incremental development is any combination of both iterative design or iterative method and incremental build model for development

Explanation:

importance

Incremental development ensures that developers can make changes early on in the process rather than waiting until the end when the allotted time has run out and the money has been spent.

An incremental approach breaks the software development process down into small, manageable portions known as increments. Each increment builds on the previous version so that improvements are made step by step

The article upon which the question is based on:

The Skunk Works home page describes this team best: "What do the world’s first stealth aircraft, the world’s most advanced fighters, and the world’s fastest manned aircraft have in common? They were all imagined by ‘Skunks’—some of the most innovative, strategic, and visionary thinkers around." Kelly Johnson was permitted to build an experimental engineering department in 1943, and the rest is history. The small-staffed unit was organized by integrating designers with builders, working together so that ideas were buildable, with limited visitors allowed from the outside. The impressive results are many, including the U-2, the world’s first spy plane, and the SR-71 Blackbird, the world’s fastest, highest-flying aircraft.

Answer:

1. comprehensive

2. sequential

Explanation:

Skunkworks appeared to have COMPREHENSIVE task interdependence, while the Levittown builder seemed to have SEQUENTIAL task interdependence.

This is based on the idea that Skunkworks acknowledges the powers of interaction and coordination of team members and while Levittown builders work on gradual working arrangement as one input of part A becomes the input of part B, and it goes on.

Answer:

A good identifier for a variable that will be used to hold an employee’s phone number is:

a. EmployeePhoneNumber

Explanation:

An identifier is a string that uniquely identifies or names the entity or an object.  The object or entity may be a constant, variable, structure, function, etc. Identifiers can be formed from uppercase and lowercase letters, digits, and underscores.  Meaningful identifiers mostly favor the use of long descriptive names like EmployeePhoneNumber.  However, the other options can still be used.

Answer:

D. 5

Explanation:

If the variables original value was 5 then the value that will be printed is 5. This is because the variable is being passed as a parameter into the function and 5 is being added to the parameter value, not the actual global variable outside. Therefore, in order for the adjusted value to be printed then that new value that is returned by the function needs to be saved in a new variable. This can be seen in the example code below.

Answer:

[tex]\tan(x+y) = 3.73[/tex]

Explanation:

The missing part of the question are:

[tex]\sin(x) = \frac{1}{2}[/tex]

[tex]\cos(y) = \frac{\sqrt 2}{2}[/tex]

Required

[tex]\tan(x + y)[/tex]

First, we calculate [tex]\sin(y)[/tex] and [tex]\cos(x)[/tex]

We have:

[tex]\sin^2(x) + \cos^2(x) = 1[/tex]

So:

[tex](1/2)^2 + \cos^2(x) = 1[/tex]

Collect like terms

[tex]\cos^2(x) = 1 - (1/2)^2[/tex]

[tex]\cos^2(x) = 1 - \frac{1}{4}[/tex]

Take LCM

[tex]\cos^2(x) = \frac{4-1}{4}[/tex]

[tex]\cos^2(x) = \frac{3}{4}[/tex]

Square roots of both sides

[tex]\cos(x) = \frac{\sqrt 3}{2}[/tex]

Similarly,

[tex]\sin^2(y) + \cos^2(y) = 1[/tex]

So:

[tex]\sin^2(y)+(\sqrt 2/2)^2 = 1[/tex]

[tex]\sin^2(y)+ (2/4) = 1[/tex]

[tex]\sin^2(y)+1/2 = 1[/tex]

Collect like terms

[tex]\sin^2(y) = 1 - 1/2[/tex]

Take LCM

[tex]\sin^2(y) = \frac{2 -1}{2}[/tex]

[tex]\sin^2(y) = \frac{1}{2}[/tex]

Square roots of both sides

[tex]\sin(y) = \frac{1}{\sqrt2}[/tex]

Rationalize

[tex]\sin(y) = \frac{\sqrt2}{2}[/tex]

So, we have:

[tex]\sin(x) = \frac{1}{2}[/tex]           [tex]\cos(x) = \frac{\sqrt 3}{2}[/tex]

[tex]\cos(y) = \frac{\sqrt 2}{2}[/tex]        [tex]\sin(y) = \frac{\sqrt2}{2}[/tex]

[tex]\tan(x) = \sin(x) \div \cos(x)[/tex]

[tex]\tan(x) = \frac{1}{2} \div \frac{\sqrt 3}{2}[/tex]

Rewrite as:

[tex]\tan(x) = \frac{1}{2} * \frac{2}{\sqrt 3}[/tex]

[tex]\tan(x) = \frac{1}{\sqrt 3}[/tex]

Rationalize

[tex]\tan(x) = \frac{\sqrt 3}{3}[/tex]

Similarly

[tex]\tan(y) = \sin(y) \div \cos(y)[/tex]

[tex]\tan(y) = \frac{\sqrt 2}{2} \div \frac{\sqrt 2}{2}[/tex]

[tex]\tan(y) = 1[/tex]

Lastly,

[tex]\tan(x + y)= \frac{\tan(x) + \tan(y)}{1 - \tan(x) \cdot \tan(y)}[/tex]

[tex]\tan(x + y)= \frac{\frac{\sqrt3}{3} + 1}{1 - \frac{\sqrt3}{3} \cdot 1}[/tex]

[tex]\tan(x + y)= \frac{\frac{\sqrt3}{3} + 1}{1 - \frac{\sqrt3}{3}}[/tex]

Combine fractions

[tex]\tan(x + y)= \frac{\frac{\sqrt3+3}{3}}{\frac{3 - \sqrt3}{3}}[/tex]

Cancel out 3

[tex]\tan(x + y)= \frac{\sqrt3+3}{3 - \sqrt3}[/tex]

Using a calculator

[tex]\tan(x+y) = 3.73[/tex]

Answer:

So we can maintain high quality designs at any graphic scale.

Explanation:

Unlike other graphic formats which simply define colors for fixed pixels, vector graphics define points and shapes (vectors) which are then used to draw the graphic at the desired and appropriate resolution.

Our graphic can look good at any resolution, no matter how large it gets. If we take a png or jpg file and make it extremely large, you'll notice the image begins to get blurry, because the pixels are being stretched and colors are being predicted or matched for the larger scale.

       int[] myArr = new int[10];

       for (int i = 0; i < 10; i++) {

           System.out.print("Enter an integer: ");

           myArr[i] = in.nextInt();

           System.out.print('\n');

       }

       SelectionSortDescendTrace(myArr);

   }

   public static void SelectionSortDescendTrace(int[] myArr) {

       int temp;

       for (int i = 0; i < myArr.length; i++)

       {

           for (int j = 0; j <myArr.length; j++)

           {

               if (j != myArr.length - 1)

               {

                   if (myArr[j] < myArr[j + 1])

                   {

                       temp = myArr[j];

                       myArr[j] = myArr[j + 1];

                       myArr[j + 1] = temp;

                   }

               }

           }

           System.out.println(Arrays.toString(myArr));

Answer:

d. ask customers to respond to a brief survey of their attitudes regarding life insurance.

Explanation:

A life insurance policy can be defined as a contract between a policyholder and an insurer, in which the insurer agrees to pay an amount of money to a specific beneficiary either upon the death of the insured person (decedent) or after a set period of time.

A salesperson (sales representative) refers to an individual or employee who is saddled with the responsibility of taking orders from customers, as well as selling finished goods and services to consumers or end users.

A foot-in-the-door phenomenon can be defined as a compliance (persuasive) technique or tactics that assumes a person agreeing to perform a small request increases the likelihood of he or she agreeing to a subsequent larger request. Thus, it posits that when a person agrees to a small, it makes it difficult for him or her to decline a second, larger (bigger) request.

In this context, a life insurance salesperson who takes advantage of the foot-in-the-door phenomenon would most likely ask his or her customers to respond to a brief survey of their attitudes regarding life insurance.

i) Total time = 2457.73 secs

ii) BDP = 0.01 Mbyte

Explanation:

Packet size : 2 Kb = ( 2 * 8192 ) bits = 16384 bits

Bandwidth : 2Mbps = 2,000,000 bits/sec

RTT = 50 ms = 0.050 secs

i) Determine total time required to transfer 500 kB

= Initial handshake + Time for transmission of all files + propagation delay

= 2 x RTT +  Time for transmission + RTT /2

Total time = ( 2 * 0.05 ) +  (1500 * 1.6384 )+ ( 0.050 / 2 ) = 2457.73 secs

ii) Determine the Bandwidth-delay product

= data link capacity * RTT

= 2 Mbps  * 50 ms =  100,000 =  0.01 MByte

Answer:

Yes, because the upper limit is less Than 8 minutes

Explanation:

According to the empirical formula :

68.26% of data lies within 1 standard deviation from the mean;

Hence,

Mean ± 1(standard deviation)

The sample mean and sample standard deviation of the given data is :

Sample mean, xbar = Σx / n = 546 / 100 = 5.46

Sample standard deviation, s = 2.475 (Calculator)

The interval which lies within 68.26% (1 standard deviation is) ;

Lower = (5.460 - 2.475) = 2.985

Upper = (5.460 + 2.475) = 7.935

(2.985 ; 7.935)

Since the interval falls within ; (2.985 ; 7.935) whose upper level is less than 8 means patients will have to wait less Than 8 minutes.
