Adam is evaluating the security of a web server before it goes live. He believes that an issue in the code allows an SQL injection attack against the server. What term describes the issue that Adam discovered?
A. threat
b. vulnerability
c. risk
d. impact
The term vulnerability describes the issue that Adam discovered.
b. vulnerability
Explanation:
SQL injection attack is an attack in which an external party can execute SQL commands on the database that serves as a back-end for a particular website. The SQL commands can be used to modify the contents of the website, modify the records, delete the records, and retrieve confidential information as well.
As Adam believes that the code has an issue that allows a SQL injection attack, the term that best describes the issue that he discovered is vulnerability. The website is vulnerable since the code does not have a proper procedure to tackle a situation of SQL injection attack.

Classes cannot:
A) Be derived from other classes
B) Initialize data members in the class definition
C) Be used to model attributes and behaviors of objects
D) Include objects from other classes as members
Classes cannot Initialize data members in the class definition.
B) Initialize data members in the class definition
Explanation:
Class is defined by end user data type where it can handle multiple data type and referred to other classes also. Class is also called as data structure object or object class.
Due to class methods total programming language coding style is changes. For example employee of an organization should hold his or her employee number, address detail, spouse details, salary details
Where in old style programming language we need to declare separate variable to hold the data types, where we can define employee as class which can hold employee number, address fields, and again define salary details as other class and add employee->employee number where key connect between to class which is called derived class.
Which security technology inspects network traffic, attempting to find matches to suspected malicious or unauthorized activity based on the content of the packets, and is limited to being able to only log or send alerts on that malicious activity?
Answer:
Intrusion Detection System (IDS)
Explanation:
An Intrustion Detection System (IDS) is an application software or hardware device that monitors network traffics or systems. It searches the network or system for threats. These threats could be (but not limited to) suspicious activities or malicious activities or policy violations.
Once a threat is observed, it beeps or alerts the system administrator(s). Also, all these threats are then logged in a security information and event management (SIEM) system.
But an IDS cannot block or prevent threats on the system.

A hardware compatibility list recommends striping with double parity as storage for an application. In a test environment, a technician realized that a different RAID level can be used to compensate for a limited number of available disks. Which of the following is the closest RAID level the technician should deploy while minimizing the number of disks and maintaining fault tolerance.
Answer:
RAID level 5 can be used to compensate a limited number of available disks.
Explanation:
There are two type of RAID
Software RAIDHardware RAIDSoftware RAID
deliver services form the host.
Hardware RAID
provides hardware services.
RAID has levels
0, 1, 5, 6, and 10
RAID 0, 1, and 5 work on both HDD and SSD media,
4 and 6 also work on both media.
RAID 0 :Striping
In this level minimum of two disks,RAID 0 split the file strip the data.Multiple hard drive are used to split the data.
RAID 1 : Mirroring
In this level Minimum two disk require and provide data tendency.
RAID 5 :Stripping with parity
Parity is a binary data.RAID system calculate the value which system used to recover the data.
Most RAID system with parity function store parity blocks.
RAID 5 combines the performance of RAID 0 with redundancy of RAID 1.
RAID 5 level should minimize the fault tolerance.
When connecting a trunk link between two switches, it is important to configure the allowed VLANs correctly on either end. If this is not done correctly _________ will occur.
Answer: A VLAN mismatch
Explanation:
The VLAN mismatch is the process when the both ends of the truck line are not connected correctly and properly between the two switches.
The configuration of the VLAN is done correctly as it is important to connecting the VLAN on either of the ends for avoiding the VLAN mismatch occurrence. By default the truck allow the VLAN 2094 for traversing the trunk by using the native VLAN in the form of VLAN 1.Therefore, VLAN mismatch is the correct answer.
In a(n) ____ design, the remote user’s keystrokes are transmitted to the mainframe, which responds by sending screen output back to the user’s screen.A. closedB. distributedC. openD. centralized
Answer:
D. centralized
Explanation:
Centralized design is a type of computing architecture where all or most of the processing/computing is performed on a central server. Centralized computing enables the deployment of all of a central server's computing resources, administration and management. The central server, in turn, is responsible for delivering application logic, processing and providing computing resources to the attached client machines.
Therefore in centralized design, the remote user’s keystrokes are transmitted to the mainframe, which responds by sending screen output back to the user’s screen
Final answer:
The correct answer is D. In a centralized design, a user's keystrokes are sent to the mainframe, which processes the input and sends the output back to the user's screen.
Explanation:
In a centralized design, the remote user's keystrokes are transmitted to the mainframe, which responds by sending screen output back to the user's screen.
This setup is typical of traditional mainframe environments, where a powerful central computer (the mainframe) handles processing and storage, while user terminals mainly serve as input and output points.
The centralized computing model contrasts with distributed computing, where processing is spread across multiple machines.
Which category of management information systems (MIS) combines the forecasting capability of decision support software with the records keeping capability of transaction processing systems software to help businesses manage inventories efficiently?
Answer:
The answer is "SCMS".
Explanation:
MIS stands for management information systems. This system studies information systems and use in business and other organizations. This system is categories in many forms in which SCMS helps businesses manage inventories.
The SCMS stands for Serial Copy Management System. It is a system that allows users to copy digital content by showing how much they would copy. In this process, the user will be copying digital information via authorization flags.On a compromised computer, you have found that a user without administrative privileges was able to perform a task limited to only administrative accounts. What type of exploit has occurred?
a. privilege escalation
b. DNS cache poisoning
c. man-in-the-middle
d. ARP poisoning
Answer:
a. privilege escalation
Explanation:
Privilege escalation is the act of exploiting a bug, design flaw or configuration oversight in an operating system or software application to gain elevated access to resources that are normally protected from an application or user.
Thus, if a user without administrative privileges was able to perform a task limited to only administrative accounts, this can be called as privilege escalation.
DNS cache poisoning is a type of attack that exploits vulnerabilities in the domain name system (DNS) to divert Internet traffic away from legitimate servers and towards fake ones.
A man-in-the-middle attack is an attack where the attacker secretly relays and possibly alters the communications between two parties who believe that they are directly communicating with each other.
ARP poisoning is a technique by which an attacker sends Address Resolution Protocol messages onto a local area network.
The exploit that occurred is a privilege escalation attack, allowing a non-administrative user to perform administrative tasks.Therefore the Correct Option Is a. privilege escalation.
The Correct Answer Is a. privilege escalation. This exploit allows a user to gain elevated access to resources that are typically restricted for higher-level accounts.
Here are definitions of the incorrect options:
DNS cache poisoning: This attack involves substituting addresses in the DNS cache so that the computer is redirected to another device.Man-in-the-middle: This is where the attacker intercepts communication between two parties and can modify or eavesdrop on the conversation.ARP poisoning: In this attack, falsified ARP messages are sent over the local network to link the attacker’s MAC address with the IP address of a victim, allowing unauthorized access.The Open Systems Interconnection (OSI) is a conceptual model whose purpose is to make networks more manageable. Its objectives include allowing for more portable hardware and software integration, the creation of standard interfaces that would allow manufacturers of different systems to interconnect their equipment and the creation of a model that would be used world-wide. There are seven layers to the OSI. The lowest - or first - layer allows a contiguous sequence of bits to be transmitted through the network. Which is the first layer: A. data-link layer, B. physical layer, C. network layer, D. transport layer
Answer:
A. data-link layer
Explanation:
Data-link layer is the first layer and allows a contiguous sequence of bits to be transmitted through the network.
On top of it is the Network Layer and it handles the task of routing network messages from one computer to another.
Then comes the Transport Layer which is the basic layer at which one network computer communicates with another network computer.
The first layer of the OSI model is the Physical Layer, which is responsible for the transmission of raw bit streams over a physical medium.
The Open Systems Interconnection (OSI) model is a conceptual framework used to understand and design network systems. It divides network communications into seven distinct layers, each with its own specific function. The first and lowest layer is the Physical Layer, which deals with the transmission of raw bit streams over a physical medium, such as cables and switches.
The seven layers of the OSI model are:

Explanation:
In cell c11, enter a formula to reference the date stored in cell b7. insert a nested function in cell c12 to calculate the date for the next payment. nest the year, month, and day functions within the date function. add 1 to the month result. copy the function to the range c13:c34.
Final answer:
The student needs to reference a date in one cell and create a formula for the next payment date in another cell using spreadsheet functions. In cell C11, they will reference the date with =B7, and in cell C12, they will use a nested formula =DATE(YEAR(B7), MONTH(B7) + 1, DAY(B7)) which is then copied down to subsequent cells.
Explanation:
The student is asking about how to use spreadsheet functions to reference and manipulate dates. In cell C11, the formula to reference the date stored in cell B7 would simply be =B7. For cell C12, the nested function to calculate the next payment date, adding one month to the current date, would be something like =DATE(YEAR(B7), MONTH(B7) + 1, DAY(B7)). This uses the YEAR, MONTH, and DAY functions nested within the DATE function to construct the new date. Once the function is entered in cell C12, it can be copied down the range C13:C34 to apply to additional cells. Remember, these functions and formulas are typical of spreadsheet software like Microsoft Excel ora Sheets.
What would be the results of the following code?final int SIZE = 25;int[] array1 = new int[SIZE];... // Code that will put values in array1int value = 0;for (int a = 0; a < array1.length; a++){value += array1[a];}a.value contains the highest value in array1b.value contains the lowest value in array1c.value contains the sum of all the values in array1d.This would cause the program to crash
Answer:
The correct option to this code is "a".
Explanation:
The given code contains the highest value in array1 because code will use variable value that adds all value of array1. and other options are not correct that can be described as:
In option, b The value variable, we add a number that's why it can not contain the lowest value.In option, c The value variable use for loop for add all array element not sum of values.In option, d There will no crash in program.
What is aperture priority mode? When might you use this mode on a camera? What is depth of field? How can you adjust the depth of field in a photograph? What is the relationship between aperture and shutter speed? How can you describe this relationship? What is the landscape mode? How does this mode adjust the aperture? What is the result of this adjustment? How is shutter speed generally measured? What do the measurements mean? How is aperture measured? What do the measurements mean? Why is learning to control aperture and shutter speed important? Which camera mode do you think you are most likely to use? Why? Have you tried to take some action photographs of people, animals, or other objects? How did the photographs turn out? What are some of the challenges with taking action photographs? What are some of the difficulties of taking night photographs? How can you reduce these challenges?
Answer:
Please check explanation
Explanation:
We abbreviate aperture priority by A or Av( which is used for aperture value) on the camera mode call up, which is an adjustment on some of the cameras which leverage the user to adjust the certain value of the aperture or the f-number as meanwhile the camera adjust the speed of the shutter ensuring it matches it, and which results in a good exposure depending on the condition of the light as being measured via the light meter. And this is not the same as the manual mode, in which the user is compelled to make the decision for both the values, the priority of the shutter, the location the user selects the shutter speed while the camera picks up the correct aperture, as well as the program state, where camera picks each of them.
So the first two questions are answered. Let's see the third, the depth of the field. It is the distance from the nearest to the furthest objects which provides an image being selected for being at the focus in a camera.
Hence the depth of the field means the range of the sharp focus in a certain photograph. And while you shoot with the help of the larger camera like the DSLR, you will be able to adjust the depth through the adjustment of the aperture of the lens. The aperture is nothing else but the opening within the lens which manages the amount of the light that is permitted via the lens.
Now come to the fifth question. The shutter speed and the aperture are being related directly. It improves the aperture (by a stop). And each of them comes up with the very best exposure through the permitted weight of light.
And both of them are related to each other in an inverse proportion. And both of them must be balanced for ensuring that the image is not being exposed or less exposed to the permitted light. And when the aperture is increased the shutter speed increased for balancing it as well as vice versa.
Landscape mode:
It is the kind of page orientation that prints out the picture in a horizontal manner rather than in a vertical manner. And it is being commonly used for printing the charts or various other types of pictures as well as the text which might not adjust properly with the page that is aligned vertically.
Consider the High Nikon DSLR. You need to hold down the "MODE" as meanwhile the rear control (dial) is turned unless you view "A" over the LCD top. And your FCD then sets the aperture. And in almost all Canon SLRs as an example: You need to turn to "Av" your mode dial.
The results of these adjustments are certainly good.
And the shutter speed is being measured by the unit of time and ranges in less than fractions of one second. And as we say that the shutter speed is "5000", it means its 1/30000 th of a minute. And the shutter speed which is of one second or more in length is being marked as a'. One example is 16'.
How we measure aperture. And what it means:
It is being measured with the help of the f-stop scale. And on the digital camera, you will find 'f/' which is being followed by an integer. And this f-number indicates the wideness of the aperture. As well as the size does affect the exposure as well as the field depth of the resultant image.
Now come to why we should learn to control the shutter speed and the aperture.
You should know that by selecting the shutter speed you permit yourself to freeze or otherwise blur motion, and sometimes you would like to do the first one or the second one. And the aperture permits you to select the field depth to either blur the background or make it sharper.
Thus, now you have an idea of each of the modes, and their merits. And if you will ask the best one, he will be up with the aperture priority or with auto ISO and full manual. If you are up with some specific requirements, then you should have a full manual mode in automatic mode, and that will be quite handy. You certainly need to learn by heart how to make use of the full manual, as it will improve your understanding of the photography, however, the semi-automatic mode is certainly your best friend.
And yes, as well as its a very great feeling. Its certainly quite hard to take the photographs of still objects while you are riding.
Some of the things that make it hard to take the action photographs are like the object, or the animal can move as well as you need to set the shutter speed as well as the aperture speed quite swiftly. Also, you need to focus your camera for ensuring a very good picture and ensure its not blurry or like the picture is out of the focus.
In night photography, the camera might shake because of the very low ambient brightness, the camera might move for very slow shutter speed. Various other challenges are the improper focus, white balances, less exposure, etc,
That solves all the questions asked.

A 5.5 g sample of a substance contains only carbon and oxygen. Carbon makes up 35% of the mass of the substance. The rest is made of oxygen. You are asked to determine the mass of oxygen in the sample. Which of the following expressions demonstrates a mathematical procedure to solve this problem using the proper order of operations?
((100 - 35)/100) x 5.5 grams =
100 - 35/100 x 5.5 grams =
100 - (35/100) x 5.5 grams =
Recall that to calculate a percent of an amount in grams means you have to convert the percent to a number and multiply by the amount in grams. For example, 50% means 50 out of 100, or 50 hundredths. So 50% of 10 grams is 0.50 times 10 grams. You need to take 0.50 and multiply it by 10 grams to determine 50% of 10 grams is 5.0. (50% and 10 grams are examples and not numbers for this problem.)
Answer:
((100-35)/100) x 5.5grams=3.575grams of oxygen
Explanation:
Since ha sample contains 35% carbon which means (100-35)=65% is oxygen in the sample. In order to calculate the mass of oxygen in the sample we have to find the 65% of 5.5g which means we have to multiply 65/100=0.65 with 5.5g i.e 0.65*5.5. so the mathematical expression we use will be:
((100-35)/100) x 5.5grams=3.575grams of oxygen

Which line in the following program contains the header for the showDub function? 1 #include 2 using namespace std; 3 4 void showDub(int); 5 6 int main() 7 { 8 int x = 2; 9 10 showDub(x); 11 cout << x << endl; 12 return 0; 13 } 14 15 void showDub(int num) 16 { 17 cout << (num * 2) << endl; 18 } 1. 4 2. 6 3. 10 4. 1
The header for the showDub function is contained in line 4.
The header of a function in C++ is the first line where the function is declared before it is defined or called. It specifies the return type, the name of the function, and the parameters the function will take, if any. In this case, line 4, 'void showDub(int);' is where the function showDub is declared, making it the function's header. This is a forward declaration and tells the compiler what the function looks like. This allows the function to be called before it is fully defined, as seen in line 10 within the main function. The actual definition of the showDub function does not occur until line 15, where the function's operations are fully described.
