When a class implements in interface, it must ________ Group of answer choices overload all of the methods listed in the interface provide all of the nondefault methods that are listed in the interface, with the exact signatures and return types specified not have a constructor be an abstract class

Answers

Answer 1

Answer:

provide all of the nondefault methods that are listed in the interface, with the exact signatures and return types specified

Explanation:

I am assuming the programming language is Java. Actually, none of the answers are 100% correct, but this one is the only one that is partially correct. The reason is the class implementing an interface can be abstract, and in this case it may not provide ALL nondefault methods.

Answers

Since Tristen want her students to take notes on her presentations, she should have some sort of handout.

Because Wyatt, wants to ensure that students who do not have PowerPoint can still view his presentations, converting it into a pdf is best.

Since Reed's students are very visual, converting his slides into a video will make it better for students who want to spend some time assessing some of the graphs or equations.

Thus, A is the best choice.

The program prompts the user for five to ten numbers all on one line, separated by spaces, calculates the average of those numbers, and displays the numbers and their average to the user.

The program uses methods to:

1) get the numbers entered by the user all on one line separated by spaces;

2) calculate the average of the numbers entered by the user; and

3) print the results.

The first method should take no arguments and return a String of numbers separated by spaces.

The second method should take a String as its only argument and return a double (the average).

The third method should take a String and a double as arguments but have no return value.

IF user input is: 20 40 60 80 100

What types of customizations have you or would you make to your operating system, and why?

Answers

Answer:

Explanation:

I have made a couple of customizations to my OS, which is Windows 10. The first being that I activated dark mode, this feature turns the entire OS into a dark-themed color, including apps and menus. This makes using the computer for extended hours much easier on the eyes. The other very important customization I added was a hover taskbar. This allows me to add many important shortcuts to the taskbar which all appear when I hover over the taskbar. It makes my desktop much cleaner and I have quick and easy access to my most important applications.

why the internet is not policed​

Answers

Answer:

The Internet allows people to circumvent law by committing criminal acts from areas where their activities are not illegal. Those areas will always exist, and thus new regulations will be just as ineffective as the old ones are ["Net Needs Law Enforcement, Author Says,"]. But Internet traffic is marked with IP addresses, and those addresses can be tied to specific networks with specific locations. Shouldn't it be possible to separate traffic based on the originating network and treat data coming from relatively insecure locations differently than data coming from relatively secure locations? It would be much harder for someone in a rogue nation to hack a network if he had to hack an intermediary network first. And unlike government regulation, which has zero impact in areas where these threats are likely to originate, separating traffic by location might actually work

Mary uploaded some images on her website. She chose an image and downloaded it. She found that the image she saw on screen did not seem to have the same DPI as when she had scanned it (she had uploaded a scanned image with 300 DPI). What could be reason with this visual decrease in DPI on the computer screen? (Correct Answer only)

A. Some image resolution was lost while uploading it
B. She downloaded a compressed version of the image.
C. The computer reset the resolution of the image.
D. Her file was probably corrupted while downloading.
E. Computer screens typically display images of only 72 DPI.

Answers

It could be A or B, with a guess that it’s A. Many websites require images to be compressed on uploading so that it takes less of the site’s database storage, but the wording leads me to believe it may be B. Any thoughts?

The reason for this visual decrease in DPI on the computer screen is some image resolution was lost while uploading it. The correct option is A.

What is resolution?

Resolution is the quality of the image that we see in the screen. It is the number of pixels per inch of space. The meaning of PPI is pixel per inch. When a high-resolution picture is seen, it means there are more pixels per inch.

When a picture is downloaded from a site. It does not download in the original pixels because during downloading some pixels are lost due to slow net or the settings of the computer. And a compressed version does not download on its own, and corrupted files do not affect the resolution.

Thus, the correct option is A. Some image resolution was lost while uploading it.

TLS downgrade vulnerability on a server in a development network In order of risk, which of the following should be patched FIRST?
A. Microsoft Office Remote Code Execution
B. SQL injection
C. SSL/TLS not used
D. TLS downgrade

Answers

Answer:

A. Microsoft Office Remote Code Execution

Explanation:

From the given options, we have;

The web server having a SQL injection is infrequently use

The information on the website having SSL/TLS not used is promotional

The location of the server having  a TLS downgrade is on a development network

The location of the Microsoft Office Remote Code Execution is on a human resource system test server

Therefore, given that the test server, is the deployment source of the main server, and that with a Remote Code Execution, RCE,  cyber attack, the attacker is able to make commands work on other computers, the RCE attack on the test server is a potential access of an attack on the main servers, and should be patched first.

You are concerned about attacks directed at your network firewall. You want to be able to identify and be notified of any attacks. In addition, you want the system to take immediate action to stop or prevent the attack, if possible. Which tool should you use

Answers

Answer:

Intrusion Prevention System (IPS)

Explanation:

Firewall can be defined as a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules.

Simply stated, a firewall is a network security protocol that monitors and controls inbound and outbound traffic based on set aside security rules.

A firewall is used to control access to a computer or network, as it creates a barrier between a computer or a network and the internet in order to protect against unauthorized access.

Basically, it is a network security device or security system pre-installed on most computers to essentially inspect data being transmitted to or from a computer

Thus, the tool you should use is an intrusion prevention system (IPS).
