4. Scientists are not concerned with the human impact on the environment. True or False?

Tresset [83]

4. Of course the scientists are concerned, particularly the environmentalists. In fact, they are the people who find alternative ways in order to preserve out natural resources.

5. This is true. Land environments is more susceptible to pollution than water environment. Because of the assimilative capacities of the bodies of water, they can cleanse themselves.

6. False. The weather, the water quality and the forest are three of the things that have drastically changed throughout time. Because of emitting too much air pollutants into the atmosphere, it has led to global warming and climate change.

7. This is true. No matter the size of the area is, it will always be affected.

8. This is true. Biology is the study of life. So, all living things and others related to it are under its field of study.

9. This is false. The atmosphere contains the ozone layers which protects the Earth from UV rays. Without the ozone layer, life would not be possible here on Earth.

10. This is true. Nature would always go about its own cycle. It is the actions of mankind and the effect towards nature that bring about environmental problems.

Why is a DNS cache poisoning attack dangerous? Check all that apply. A. Errrr...it's not actually dangerous. B. It allows an att

larisa [96]

Answer:

(B) It allows an attacker to redirect targets to malicious webserver.

(D) It affects any clients querying the poisoned DNS server.

Explanation:

DNS cache poisoning is a serious type of attack that is designed to exploit the vulnerabilities inherent in a Domain Name Server (DNS) where a user is redirected from a real server to a fake one. It is also called DNS spoofing.

Normally, when your browser tries to visits a website through a given domain name, it goes through the DNS server. A DNS server maintains a list of domain names and their equivalent Internet Protocol addresses. This server (DNS) then responds to the request with one or more IP addresses for the browser to reach the website through the domain name.

The computer browser then get to the intended website through the IP address.

Now, if the DNS cache is poisoned, then it has a wrong entry for IP addresses. This might be via hacking or a physical access to the DNS server to modify the stored information on it. Therefore, rather than responding with the real IP address, the DNS replies with a wrong IP address which then redirects the user to an unreal website.

Although they might not be able to control your computer remotely as long as you are not trying to visit a web page via the poisoned information, there are other dangers attached to this type of attack.

Once the DNS server has been poisoned, any client trying to query the server will also be affected since there is no direct way of knowing if the information received from the server is actually correct.

Which of the following website is arguably considered the best site to search for scholarships

monitta

There is no way to define the 'best' site. Each site offers a unique experience along with the fact it might not display the same information as the other ones. The APEX site (As far as I know, it is a school test site) Won't really be able to help unless you are willing to do a few tests. I would go for Scholarshipexperts.com

1.What is the output of the following program? [10 Marks]namespace ConsoleApp1{class Program{static void Main(string[] args){int

Nataliya [291]

The program outputs the following rectangular array:

0 0 0 0

0 1 2 3

0 2 4 6

0 3 6 9

0 4 8 12

This is the correctly formatted C# program:

namespace ConsoleApp1{

class Program

{

static void Main(string[] args)

{

int i, j; // declare index variables used to iterate over the array A

int [,] A = new int[5,5]; // create a 5 by 5 array

/* Iterate over the array with the index variables i and j

and initialize each location A[i, j] with the product

of i and j. */

for (i = 0; i < 5; ++i)

{

for (j = 0; j < 4; ++j)

{

A[i, j] = i*j;

}

/* Iterate over the array again. This time, swap locations

A[i, j] with A[j, i] */

for (i = 0; i < 5; ++i)

{

for (j = 0; j < 4; ++j)

{

if (i < 5)

{

A[j, i] = A[i, j];

}

else

break;

// display the current location A[i, j]

Console.Write(A[i, j] + " ");

}

/* print a newline to prepare for the next line of printing

which corresponds to the next column i */

Console.WriteLine();

// pause and wait for user keypress before continuing

Console.ReadLine();

}

When executed, this program simply prints a rectangular array like so;

0 0 0 0

0 1 2 3

0 2 4 6

0 3 6 9

0 4 8 12
