a) Bastion Host
b) Screened subnet
c) Screened host
d) Screened
Answer:
b) Screened subnet
Explanation:
In Computer science, Firewall implementation and design for an enterprise can be a daunting task. Choices made early in the design process can have far-reaching security implications for years to come.
Screened subnet firewall architecture is designed to host servers that offer public services.
In network security and management, one of the network architecture used by network engineers for the prevention of unauthorized access of data on a computer is a screened subnet. A screened subnet can be defined as a network architecture that uses a single firewall with three screening routers as a firewall.
A screened subnet is also known as a triple-homed firewall, this is because it has three (3) network interfaces;
1. Interface 1: it is known as the external or access router, which is a public interface and connects to the global internet.
2. Interface 2: it is known as the demilitarized zone or perimeter network, which acts as a buffer and hosted public servers (bastions host) are attached herein.
3. Interface 3: it is known as the internal router, which is a subnet that connects to an intranet.
The screened subnet when properly configured helps to prevent access to the internal network or intranet.

While working on an investigation, a colleague hands you a list of file creation and access times taken from a compromised workstation. To match the times with file access and creation times from other systems, what do you need to account for
Answer:
Record time offsets.
Explanation:
In this scenario, to match the times with file access and creation times from other systems, you will need to account for time offsets.
The time offset refers to the time stamp associated with different processes or tasks on a computer in nanoseconds through the operating system.
Since you've been handed a list of file creation and access times taken from a compromised workstation by your colleague, you'll need to match respectively the time the file was created to the time it was accessed by an unauthorized user.
Additionally, the time stamp varies depending on the operating system being used;
- For windows operating system, it uses a 64 bit time stamp.
- For Linux or Unix, it uses a 32 bit time stamp.
Proxy servers and ACLs on network devices are examples of non-security devices with security features, while firewalls and IDS/IPS systems are the network's specialized security devices. Group of answer choices
Complete Question:
Proxy servers and ACLs on network devices are examples of non-security devices with security features, while firewalls and IDS/IPS systems are the network's specialized security devices.
Group of answer choices:
A. True.
B. False.
Answer:
A. True.
Explanation:
A proxy server is an example of non-security devices with security features because it acts as a hub or gateway between a user and the internet. Therefore, when a user request for resources through a website, the proxy server acts as an intermediary between them and the web server providing such resources.
ACL is an acronym for access control list and it comprises of rules that grant or deny access to resources on a network.
A firewall is a network security system which prevents unauthorized access on a private network by monitoring, controlling and filtering inbound and outbound network traffic (packets) based on a set of security rules.
IDS and IPS are acronym for intrusion detection system and intrusion prevention system respectively. IDS is a security system which monitors the network traffic and notifies the engineer when there's a malicious activity. IPS is a security system which monitors the network traffic and blocks malicious activity as well as keeping logs.
Hence, Proxy servers and ACLs on network devices are examples of non-security devices with security features, while firewalls and IDS/IPS systems are the network's specialized security devices.
Which statement is true?
a. When a method call is made, the called method must know how to return to its caller, so the return address is pushed onto the program execution stack.
b. Stacks support recursive method calls in the same manner as conventional, nonrecursive method calls.
c. The program execution stack contains the space created for a method's global variables on each invocation of that method during a program's execution.
d. When a method returns to its caller, the memory for that method's local variables is popped off the stack and those variables are no longer known to the program.
Answer: D) When a method returns to its caller, the memory for that method's local variables is popped off the stack and those variables are no longer known to the program.
Explanation:
Read the following code used to calculate the total cost of an item with tax: price = input("What is the item price? ") tax = price * 0.065 totalPrice = price + tax There is an error in the code. What type of function needs to be used? (5 points) float() int() print() str()
Answer: float()
Explanation: The code used to calculate total price = tax + price.
price = input("What is the item price? ")
tax = price * 0.065
totalPrice = price + tax
Since the input required from the user will be numerical, that is the price of an item, then it has to be stated explicitly, instead the code throws an error as it will read in a string if not stated explicitly.
Also, Given that the total price calculation will require decimal or fractional calculations, using the float() function will allow the program to read in the user input as a numerical value which can be used in further calculation as the float () function provides flexibity when working with fractional values.
Write a loop that reads positive integers from standard input and that terminates when it reads an integer that is not positive. After the loop terminates, it prints out, on a line by itself, the sum of all the even integers read. Declare any variables that are needed. ASSUME the availability of a variable, stdin, that references a Scanner object associated with standard input
Answer:
Written in Java Programming Language
import java.util.Scanner;
public class Assign{
public static void main(String [] args) {
Scanner stdin = new Scanner(System.in);
int num,sum=0;
System.out.println("Start Inputs: ");
num = stdin.nextInt();
while (num>=0) {
if(num%2== 0)
{
sum+=num;
}
num = stdin.nextInt();
}
System.out.print("Sum of even numbers: "+sum);
}
}
Explanation:
I'll start my explanation from line 4
This line initializes Scanner object stdin
Scanner stdin = new Scanner(System.in);
This line declares necessary variables and initializes sum to 0
int num,sum=0;
This line prompts user for inputs
System.out.println("Start Inputs: ");
This line reads user inputs
num = stdin.nextInt();
This line checks is user input is not negative (It's a loop that will be repeated continually until a negative number is inputted)
while (num>=0) {
This line checks if user input is an even number
if(num%2== 0)
{
If the above condition is true, this line calculates the sum of even numbers
sum+=num;
}
This line prepares the user for next input
num = stdin.nextInt();
}
This line prints the calculated sum of even number; If no even number is inputted, the sum will be 0
System.out.print("Sum of even numbers: "+sum);
Write a program segment with a do-while loop that displays whether a user-entered integer is even or odd. The code should then ask the user if he or she wants to test another number. The loop should repeat as long as the user enters 'Y' or 'y' . Use a logical OR operator in the do-while loop test expression
Answer:
Following is the program in C++ program
#include<iostream> // header file
using namespace std; // namespace
int main() // main function
{
int num1 = 0; // variable declaration
char test;// variable declaration
do
{
cout << " Enter the number: ";
cin >> num1; //Read the input by the user
if (num1 % 2 == 0) // check the condition of even
cout << " number is even.\n";
else // check the condition of odd
cout << "Number is odd.\n";
cout << " Do you wanted the another test of number (y/n)? ";
cin >> test; //Read the input by user
} while (test == 'y' || test == 'Y'); //terating the loop
return 0;
}
Output:
Enter the number:45
number is even.
Do you wanted the another test of number (y/n) Y
Enter the number:5
Number is odd.
Do you wanted the another test of number (y/n) n
Explanation:
Following are the description of program
Declared a variable "num1" as integer type and initialized as 0 to them Declared a variable "test" as char type .After that iterating the do -while loop .Read the value by the user in the "num1" variable .Check the condition of even and odd by using % operator .Read the value of test by the user .If the user enter Y or y then loop again executing otherwise not .Could someone give an example or tell me what all of these mean?

In cell B12, enter a formula to calculate the amount budgeted for mileage to/from Airport. The amount is based on the Mileage Rate to/from Airport and the Roundtrip Mikes to Airport locates in the Standard Inputs section.
Answer:
Format the Title and Complete the Input Areas
Your first tasks are to format the title and complete the input area. The input area contains two sections: Standard Inputs that are identical for all travelers and Traveler Inputs that the traveler enters based on his or her trip.
Open e01c1Travel and save it as e01c1Travel_LastFirst.
Merge and center the title over the range A1:E1 and set the row height for the first row to 40.
Apply the Input cell style to the ranges B3:B6, E3:E4, and E6:E7, and then apply the Calculation cell styleto cell E5. Part of the borders are removed when you apply these styles.
Select the ranges A3:B6 and D3:E7. Apply Thick Outside Borders.
Enter 6/1/2018 in cell E3 for the departure date, 6/5/2018 in cell E4 for the return date, 149 in cell E6 for the hotel rate per night, and 18% in cell E7 for the hotel tax rate.
Enter a formula in cell E5 to calculate the number of days between the return date and the departure date.
Insert Formulas
The Detailed Expenses section contains the amount budgeted for the trip, the actual expenses reported by the traveler, percentage of the budget spent on each item, and the amount the actual expense went over or under budget. You will insert formulas for this section. Some budgeted amounts are calculated based on the inputs. Other budgeted amounts, such as airfare, are estimates.
Enter the amount budgeted for Mileage to/from Airport in cell B12. The amount is based on the mileage rate and roundtrip to the airport from the Standard Inputs section.
Enter the amount budgeted for Airport Parking in cell B13. This amount is based on the airport parking daily rate and the number of total days traveling (the number of nights + 1) to include both the departure and return dates. For example, if a person departs on June 1 and returns on June 5, the total number of nights at a hotel is 4, but the total number of days the vehicle is parked at the airport is 5.
Enter the amount budgeted for Hotel Accommodations in cell B16. This amount is based on the number of nights, the hotel rate, and the hotel tax rate.
Enter the amount budgeted for Meals in cell B17. This amount is based on the daily meal allowance and the total travel days (# of hotel nights + 1).
Enter the % of Budget in cell D12. This percentage indicates the percentage of actual expenses to budgeted expenses. Copy the formula to the range D13:D18.
Enter the difference between the actual and budgeted expenses in cell E12. Copy the formula to the range E13:E18. If the actual expenses exceeded the budgeted expenses, the result should be positive. If the actual expenses were less than the budgeted expense, the result should be negative, indicating under budget.
Add Rows, Indent Labels, and Move Data
The Detailed Expenses section includes a heading Travel to/from Destination. You want to include two more headings to organize the expenses. Then you will indent the items within each category. Furthermore, you want the monetary columns together, so you will insert cells and move the Over or Under column to the right of the Actual column.
Insert a new row 15. Type Destination Expenses in cell A15. Bold the label.
Insert a new row 19. Type Other in cell A19. Bold the label.
Indent twice the labels in the ranges A12:A14, A16:A18, and A20.
Select the range D10:D21 and insert cells to shift the selected cells to the right.
Cut the range F10:F21 and paste it in the range D10:D21 to move the Over or Under data in the new cells you inserted.
Format the Detailed Expenses Section
You are ready to format the values to improve readability. You will apply Accounting Number Format to the monetary values on the first and total rows, Comma Style to the monetary values in the middle rows, and Percent Style for the percentages.
Apply Accounting Number Format to the ranges B12:D12 and B21:D21.
Apply Comma Style to the range B13:D20.
Apply Percent Style with one decimal place to the range E12:E20.
Underline the range: B20:D20. Do not use the border feature.
Apply the cell style Bad to cell D21 because the traveler went over budget.
Select the range A10:E21 and apply Thick Outside Borders.
Select the range A10:E10, apply Blue-Gray, Text 2, Lighter 80% fill color, apply Center alignment, and apply Wrap Text.
Manage the Workbook
You will apply page setup options, insert a footer, and, then duplicate the Expenses statement worksheet.
Spell-check the workbook and make appropriate corrections.
Set a 1.5" top margin and select the margin setting to center the data horizontally on the page.
Insert a footer with your name on the left side, the sheet name code in the center, and the file name code on the right side.
Copy the Expenses worksheet, move the new worksheet to the end, and rename it Formulas.
Display the cell formulas on the Formulas worksheet, change to landscape orientation, and adjust column widths. Use the Page Setup dialog box or the Page Layout tab to print gridlines and row and column headings.
When approved for a loan, an individual essentially applied for aid in the area of...
A. Increasing (and financing) immediate increase in cash flow
B. limited liability
C. future educational services
D. protections and insurance
Answer:
The correct answer is A. When approved for a loan, an individual essentially applied for aid in the area of increasing (and financing), as it implies an immediate increase in cash flow.
Explanation:
Every loan involves the delivery of money by a bank or a financial agency to a person or company, with the consideration that the latter will later return said amount, plus an additional amount for interest, within a specified period and may pay in a single payment and in full or through an installment plan. But, in any case, the immediate result of said loan is an increase in the cash flow of the person who obtains said loan, which can be used for the acquisition of goods or services, or to face different eventual expenses.
An employee sets up Apache HTTP Server. He types 127.0.0.1 in the browser to check that the content is there. What is the next step in the setup process?
Answer:
Set up DNS so the server can be accessed through the Internet
Explanation:
If an employee establishes the HTTP server for Apache. In the browser, he types 127.0.0.1 to verify whether the content is visible or not
So by considering this, the next step in the setup process is to establish the DNS as after that, employees will need to provide the server name to the IP address, i.e. where the server exists on the internet. In addition, to do so, the server name must be in DNS.
Hence, the first option is correct
Your question is lacking the necessary answer options, so I will be adding them here:
A. Set up DNS so the server can be accessed through the Internet.
B. Install CUPS.
C. Assign a static IP address.
D. Nothing. The web server is good to go.
So, given your question, what is the next step in the setup process when setting up an Apache HTTP Server, the best option to answer it would be: A. Set up DNS so the server can be accessed through the Internet.
A server can be defined as a specialized computer system that is designed and configured to provide specific services for its end users (clients) on a request basis. A typical example of a server is a web server.
A web server is a type of computer that run websites and distribute web pages as they are being requested over the Internet by end users (clients).
Basically, when an end user (client) request for a website by adding or typing the uniform resource locator (URL) on the address bar of a web browser; a request is sent to the Internet to view the corresponding web pages (website) associated with that particular address (domain name).
An Apache HTTP Server is a freely-available and open source web server software designed and developed to avail end users the ability to deploy their websites on the world wide web (WWW) or Internet.
In this scenario, an employee sets up an Apache HTTP Server and types 127.0.0.1 in the web browser to check that the content is there. Thus, the next step in the setup process would be to set up a domain name system (DNS) so the server can be accessed by its users through the Internet.
In conclusion, the employee should set up a domain name system (DNS) in order to make the Apache HTTP Server accessible to end users through the Internet.

Is the IOT governable by frameworks? Explain your rationale.
Answer:
Absolutely yes.
Explanation:
IoT is an acronym for Internet of Things. This is a system of network devices connected together in order to transmit data over the internet. And since communication of these devices is over the internet, there's a need for some protocols for control and moderation. Hence, the need for IoT governance frameworks.
Some of the aspects that should be governed by these frameworks are;
i. Data confidentiality:
Data such as Social Security Numbers, Bank Verification Numbers and Credit card details, that are being transmitted in an IoT system should be assured of protection from unwanted usage or access.
ii. Data integrity:
These data should also be assured of consistency and accuracy over a long period of time.
iii. Accountability:
When there is a breach or some sort of mishappening, there has to be a body that would be held accountable.

convert thefollowing decimal number to its equivalent binary, octal, hexadecimal 255
Answer:
Binary: 11111111
Octal: 377
Hexadecimal: FF
Explanation:
Given
Decimal Number: 255
Required
Convert to
- Binary
- Octal
- Hexadecimal
Converting to binary...
To convert to binary, we take note of the remainder when the quotient is divided by 2 until the quotient becomes 0;
255/2 = 127 R 1
127/2 = 63 R 1
63/2 = 31 R 1
31/2 = 15 R 1
15/2 = 7 R 1
7/2 = 3 R 1
3/2 = 1 R 1
1/2 = 0 R 1
By writing the remainder from bottom to top, the binary equivalent is 11111111
Converting to octal...
To convert to octal, we take note of the remainder when the quotient is divided by 8 until the quotient becomes 0;
255/8 = 31 R 7
31/8 = 3 R 7
3/8 = 0 R 3
By writing the remainder from bottom to top, the octal equivalent is 377
Converting to hexadecimal...
To convert to hexadecimal, we take note of the remainder when the quotient is divided by 16 until the quotient becomes 0;
255/16 = 15 R 15
15/16 = 0 R 15
In hexadecimal, 15 is represented by F; So, the above division can be rewritten as
255/16 = 15 R F
15/16 = 0 R F
By writing the remainder from bottom to top, the hexadecimal equivalent is FF
