b.
User cannot change password.
c.
User must change password at next logon.
d.
Account is disabled.
Answer:
Option c. User must change password at next logon.
is the correct answer.
Explanation:
In the password policy for different applications, it is the common practice that whenever the user can't access his/her account due to forgetting the password or due to hacking of its account, they are provided with the password by the network administrator so that they my log on to their profiles.
Now when the user will be notified of the new password that is changed by the administrator she must change her password at next logon so that she may secure the account and remember the new password created by herself for further logons.
i hope it will help you!

Answer:The
The answer is User Cs uses the Public Key.
Explanation:
Public-key cryptography refers to a cryptographic system that uses pairs of keys: one that is a private keys,which are seen only by the use and public keys, which may be used widely by different users.
The generation of such keys depends on algorithms that are cryptographic based on mathematical problems to provide function that is one way. A strong security only needs keeping the private key private; the public key can be openly distributed among users without compromising security.
Ensuring the uninterrupted flow of information' describes which key communications and information systems principle?
A. Security
B. Reliability, Scalability, and Portability
C. Resilience and Redundancy
D. Interoperability
Answer: C) Resilience and Redundancy
Explanation:
According to the principle of communication and information system , redundancy is the factor that maintains the continuous flow of message or data even when failure is experienced in network by adding alternate or extra component in infrastructure for support.Resilience is the factors that helps network to persist even in the state of faults by keeping the main function working and recovering the fault to maintain the flow of data.Other options are incorrect because security is protection of data. Reliability factor means dependency , scalibility is changing scale of network and portability is changing position of components. Interoperability is exchanging information with devices and making use of it.Thus, the correct option is option(C).
Answer:
C. Resilience and Redundancy
Explanation:
Robust systems are characterized by having the ability to maintain their essential performance conditions despite receiving disturbances or noise. Robustness is the ability of a system to absorb stress and continue functioning, particularly when the system is subjected to unpredictable variations in its scope of performance.
The redundancy, consisting of the duplication of the critical components of a system, is developed with the purpose of granting robustness to the systems, so that in the event of the failure of a component that could jeopardize the main task or objective of the system, there is an alternative capable of replacing the system that suffers from a failure.
Robustness or resilience is characterized by two important aspects, the first is resistance to change or flexibility that is expressed as the ability of a system to resist a disturbance without undergoing irreversible change and the second is the ability of a system to recover.
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 TCP connection has reached a steady state and transmits data at a constant rate. List as many factors as you can that determine the transmission rate reached by the connection? Include the application and the operating system on both ends of the connection in your consideration.
TCP connection:
Once TCP connections reached steady state that makes end user that connectivity is stable. But end user has to do analysis the pinging time ready. for example in operating system command prompt mode ends user have to ping designation tcpip address.
Computer A
In command prompt mode end user try ping 10.10.10.10 –t (i.e. Computer B tcpip Address). End user tries to ping destination tcpip address if result comes in milliseconds then it is good connectivity rate.
Same away
Computer B
In command prompt mode end user try ping 10.10.10.20 –t (i.e. Computer A tcpip Address). End user tries to ping destination tcpip address if result comes in milliseconds then it is good connectivity rate.
End user can also check by executing TRACERT commands on designation tcpip address. End user can find how the flow of network packets travels.

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.A constructor is the code that is called when you use the 'new' keyword.
b.A constructor is declared without a return type.
Answer:
a. Partly True
b. True
Explanation:
(a) "new" keyword or syntax is used for the constructors while working in Perl and Moose object system for Perl.
For Visual Basics .Net, keyword "New" is used
For Python, "___new___" is used which allocates memory for instance and receives class as an argument.
For Objective-C, "alloc" and "init" are used for constructor method. "alloc" allocates memory for the instance and "init" handles the bulk of initializing the instance. Whereas, the "new" keyword calls both "alloc" and "init" for class instance.
(b) A constructor does not return any value because it is called by the memory allocation and object initialization code in the runtime and not directly by your code.

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.
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.
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.
You have a small wireless network that uses multiple access points. The network uses WPA and broadcasts the SSID. WPA2 is not supported by the wireless access points.
You want to connect a laptop computer to the wireless network. Which of the following parameters will you need to configure on the laptop? (Select two.)
a) AES encryption
b) TKIP encryption
c) Channel
d) BSSID
e) Preshared key
Answer:
b) TKIP encryption,e) Preshared key
Explanation:
The parameters that need to be configured on the laptop include the Temporal Key Integrity Protocol (TKIP) and the Preshared key. TKIP is an older wireless protocol that encrypts data at bit level. It is less secure as compared to the Advanced Encryption Standard (AES), AES works well with WPA2 which is not supported by the access point. The preshared key is the access password used on a shared secure channel. It is also used to validate users on the WiFi network. Once the two parameters are configured the laptop will have access to the network
To connect a laptop to a WPA wireless network, configure TKIP encryption and enter the preshared key. AES is used with WPA2 and is not applicable here, while the channel and BSSID are generally managed automatically.
Explanation:When connecting a laptop computer to a wireless network that uses WPA and broadcasts the SSID but does not support WPA2, you will need to configure certain parameters on the laptop. Since the network uses WPA, the compatible encryption that should be set up on the laptop is TKIP encryption since AES is typically used with WPA2. Additionally, you will need to enter the preshared key, which is a secret password or passphrase used to authenticate devices and grant access to the wireless network. Channels and BSSIDs are generally managed by the access points and are not typically configured manually on client devices unless troubleshooting specific connection issues or optimizing the network.

An easy way to remember the difference between encoding and decoding within the communication process is to think of encoding as the message the sender intends to say, whereas decoding can be thought of as what the receiver actually ______.
Answer:
An easy way to remember the difference between encoding and decoding within the communication process is to think of encoding as the message the sender intends to say, whereas decoding can be thought of as what the receiver actually hears.
Explanation:
Encoding and decoding are the terms used in communication.Encoding can be defined as the process or way in which the message you want to convey is created. This means the words we expel to demonstrate that what we want to say are known as encoding. Decoding on the other hand involves the interpreting of the message. It means, understanding the message that has been sent is known as decoding.As communication process have two members say sender and receiver, so sender is associated with encoding and receiver with decoding.i hope it will help you!
