This is a control structure that causes a statement or group of statements to repeat.
a. decision statement
b. constant loop
c. cout object
d0 None of these
Answer:
B. Constant Loop
Explanation:
Looping involves going over a block of code or statement infinitely or over a particular number of times. There are a number of loops, such as the infinite loop, while loop, do-while loop among others.
Infinite loop: All loops are expected to terminate after a few iterations, however, if that block of code is not available, the loop is said to be an infinite loop. This is because it will iterate continuously and indefinitely.
While loop: Also referred to as a Pretest loop, because before the statements are executed in its body, it verifies the boolean expression.
Do-while loop: Also referred to as a Posttest loop, because it tests the boolean expression after the block or statement is executed.
Answer:
D. None of these
Explanation:
The control structure that causes a statement or a group of statements to repeat is called a control loop, or simply, a loop.
In many programming languages, a loop contains a group of statements that are executed repeatedly based on a certain criterion (or condition). As long as this condition is true, the statements within the loop are executed.
Three types of control loop structure are the for, while and do...while loops.
An engineer plans to connect three switches (SW1, SW2, and SW3) in a lab. Before connecting the switches, he starts by configuring all three switches as VTP servers, with matching CTP domain name and password. He then configures some VLANs on each switch so that switch SW3 has a revision number of 10, switch SW2 has a revision number of 6, and switch SW1 has a revision number of 8. Only then does he engineer connect the switches with trunks: first SW1 to SW2, then SW2 to SW3, and then SW3 to SW1. Switch SW1 is elected the STP root switch in VLAN 1. Which answer most accurately states which VLAN configuration database is used, and why?
Answer:
c. All use SW3's database because SW3 has the highest revision number.
Explanation:
In this particular configuration, the three switches will definitely be connected to one another by the presence of some path with the specific trunks. As a result, the database with the most revision number will ultimately win. The process of the STP election does not have any influence on the selection of the VTP.

You are capturing packets with a network sniffer and notice a number of packets that are flagged by the sniffer and described as TCP retries. Which layer of the OSI model should you investigate?
Answer:
Transport Layer
Explanation:
Transport layer is responsible for correcting data transmission errors which is done by requesting retries also called re-transmission of packets in case of data loss or corrupted data.Transport layer ensures end to end delivery of data making sure that the data is received correctly and in same order in which it was sent.Transmission Control Protocol (TCP) is a protocol in this layer that continues to transmit data packets securely from sender to receiver, identifying packet losses. Transport layer works on packet loss issues and corrects data transmission errors.It has flow control and error control services manage data transmission rate and ensures data is received without error. So in case of transmission errors and re-transmission requests transport layer should be investigated.Clicking a _____ name opens a drop-down list of commands and options.

When the computer is started, a bootstrap or IPL (Initial Program Load) begins testing the system. Where is this bootstrap program stored? A) RAM B) ROM C) Hard drive D) Virtual memory
Answer:
The correct answer to the following question will be Option B (ROM).
Explanation:
Bootstrap is the programming which initializes the OS during initialization. The bootstrap loader creates small operator programs that connect and monitor the various computer hardware components.
ROM is Read-only memory, which will be used to hold a computer's start-up commands, also recognized as firmware.
No other method was used to help save system startup. ROM, then, is the right answer.
Final answer:
The bootstrap program, necessary for starting the computer and initiating the operating system loading process, is stored in ROM (Read-Only Memory), not in RAM, hard drive, or virtual memory.
Explanation:
When the computer is started, a bootstrap or Initial Program Load (IPL) begins testing the system. This bootstrap program is stored in ROM (Read-Only Memory). Unlike RAM (Random Access Memory), which is volatile and requires power to maintain its data, ROM is non-volatile and retains its data even when the computer is powered off.
This makes ROM an ideal storage medium for the bootstrap program, as it needs to be reliably accessed whenever the computer is powered on to start the operating system loading process. RAM is used as working memory for the CPU, storing data temporarily while the system is running, but not suitable for storing the bootstrap program due to its volatile nature.
Congress is debating a proposed law to reduce tax rates. If the current tax rate is r%, then the proposed rate after x years is given by this formula: r 1 1 1 1 x . Rewrite this formula as a simple fraction.
Answer:
[tex]\frac{x+1}{2x+1}r%[/tex]
Explanation:
Congress is debating a proposed law to reduce tax rates. If the current tax rate is r%, then the proposed rate after x years is given by this formula: r 1 1 1 1 x . Rewrite this formula as a simple fraction
The formula can be rewritten as thus [tex]\frac{r}{1+\frac{1}{1+\frac{1}{x} } } \\\\\ 1+\frac{1}{x} \\\frac{x+1}{x} we have \\\frac{1}{x+1/(x)} \\\frac{x}{x+1} \\1+\frac{x}{x+1} \\\frac{2x+1}{x+1}[/tex]
r%*x+1/(2x+1)
[tex]\frac{x+1}{2x+1}r%[/tex]

Assume that inputFile references a Scanner object that was used to open a file. Which of the following while loops is the correct way to read data from the file until the end of the file is reached?
Answer:
while(inputFile.hasNext()) { //some code here }
Explanation:
Even though you did not provide the options, here is how it should look like.
It is known in the question that there is an object called inputFile. To be able to read all the data from a file in Java, you need to use hasNext() function with the object. inputFile.hasNext() enables you to read the data in a file.
while(inputFile.hasNext()) { } enables you to loop through the file while it has something to read in a file.
Suppose your cell phone carrier charges you a monthly fee of $30.00 for up to 300 minutes and $0.45 for each additional minute after the first 300. Assuming you used your phone for x minutes with x > 300, the total monthly fee would be?
If you used your phone for <= 300 minutes then the charge is $30.00 Assume the user enters a positive value for the number of minutes
30 + (x -300) * .45ç correct answer
Use the following template
A = 300 #CONSTANT fee for <= 300 minutes
m = int(input("Enter the number of minutes "))
c = 0 # initialize cost variable
if (m>300): # minutes>300
# calculations here to compute the solution above
# use the correct answer provided
print(" the cost for ", m, " minutes is ", c )
else: # here m is <= 300# s <= 0
print(" the cost for ", m, " minutes is ", A )
Answer:
# 30 + (x -300) * .45ç correct answer
A = 30 #CONSTANT fee for <= 300 minutes
m = int(input("Enter the number of minutes "))
c = 0 # initialize cost variable
if (m>300):
c = 30 + ((m - 300) * 0.45) #Cost when the minute is greater 300
print("The cost for ", m, " minutes is $",c )
else:
print("The cost for ", m, " minutes is $",A )
Explanation:
c = 30 + ((m - 300) * 0.45) #Cost when the minute is greater 300
First 300 is subracted from the given minute to get the extra minute, and then the extra minute is multiplied by $0.45 after which it is added to the constant of $30 for the 300 minutes

Assume the market for DVD movies is initially at equilibrium. A decrease in the price of streamed movies, a substitute for DVD movies, will __________ the equilibrium price and ___________ the equilibrium quantity of DVD movies.
Answer:
The answer is "decrease; decrease".
Explanation:
DVD movies are used to short and a digital portable digital video, It uses a disc that stores much more data as compared to CD.
It is widely used for films and other data storage and display. It decreases the streaming video costs, as substitution for DVD videos, would increase the average demand and high the surplus in DVD films.Consider an application that transmits data at a steady rate (for example, the sender generates an N-bit unit of data every k time units, where k is small and fixed). Also, when such an application starts, it will continue running for a relatively long period of time.
Suppose that a packet-switched network is used and the only traffic in this network comes from such applications as described above. Furthermore, assume that the sum of the application data rates is less than the capacities of each and every link. Is some form of congestion control needed? Why?
Answer:
No
Explanation:
Because every link can handle the sum of the application data rate even when everyone is using the application ate the same time (worst scenario), there won't be any congestion to control. Because we have a good link capability the network doesn't require any congestion control mechanism.
Note: When trying to solve this kind of problems always keep in mind the worst scenario, if the network is capable of withstanding the worst scenario and no information about the scalability of the network is given then you don't need congestion control.

Based on the current economic situation do you expect the employment demand for graduating engineers to increase or decrease? Explain the basis for your answer.
With a significant economic recovery, what do you think will happen to future enrollments in graduating engineering programs?
Answer: the employment demand would increase.
Explanation:
Several factors affect the employment demand especially in a field as peculiar as engineering, the cumulative build up of unemployed graduates and the skill set required to fit into the present working structure is also of Paramount importance. The evaluation method for recruitment seeks to function based on this rationale by selecting a few amongst many.
Final answer:
The economic situation points to an increase in employment demand for graduating engineers, tied to economic recovery and the trend of higher job growth for those with more education. Future enrollments in engineering programs are expected to increase with economic recovery. Countries like China and India have a high number of engineering graduates, reflecting their focus on technology and industry.
Explanation:
Based on the current economic situation, the employment demand for graduating engineers is likely to increase as economies recover from downturns and companies start to expand and invest in new technologies and infrastructure. This is supported by the trend that higher levels of education, including engineering degrees, are associated with higher job growth rates. For instance, those with a bachelor's degree have job growth expectations of 17 percent.
With a significant economic recovery, enrollments in graduating engineering programs are also expected to rise. This is because students may perceive engineering as a field with strong job prospects, which can lead to more secure and well-paying positions. Therefore, during economic recoveries, the allure of a promising career in engineering could attract more students to these programs.
In the context of global engineering graduates, countries with the most graduates can be indicative of their prioritization of technical education and their industrial and technological sectors' requirements. For example, countries like China and India have high numbers of engineering graduates due partly to their large populations and emphasis on engineering as a driver of economic growth.

Explanation:
Based on the information provided within the question it can be said that in this scenario the best thing to do would be to move the computer accounts from their current location to the correct Organizational Units (OU's). This would keep things organized and have each computer account in the unit that they belong with the correct access and privileges that they need.
Which key or key sequence pressed during the boot process will allow a user to start a Windows PC using the last known good configuration?
Answer:
F8
Explanation:
In Windows PC (e.g Windows 7), Last Known Good Configuration, is an option that helps users to start up their PC if it doesn't start normally. This option is only accessible at boot process by using the keyboard (mouse will not work at this point). So to access this option, the F8 key is pressed repeatedly or held down. This will display some start up menus where the user can use the arrow keys to access the option.
Given a string variable named "myString" of length 5, how could you access the first character and last character using a numeric index?
Answer:
The first index myString[0]
The last index myString[4]
Explanation:
Indexing starts at "0". so the first character in a string will be at index "0" and the last character will be at index "-1". But since we were given the length of this string to be 5, we know that the index of the last character will be "4".
The python code bellow will print character at the first and last index:
myString = "hello"
print("The First Index is "+myString[0])
print("The Last Index is "+myString[-1])
There are certain parameters that administrators set (within a group policy or otherwise) to assist users in creating sufficiently unguessable and uncrackable passwords. One such parameter is complexity. To enforce the use of a range of complexity, what else must an administrator enforce to ensure that complex passwords are used?
Answer:
administrator must enforce a specific password length minimum
Explanation:
Based on the information provided within the question it can be said that in order to ensure that complex passwords are used the administrator must enforce a specific password length minimum. By placing a minimum on password length you are making sure that the password has a certain complexity and thus making it a lot harder for those passwords to be cracked by hackers.
If our list called List is populated as [0, 1, 2, 3, 4], what happens if our code tries to access List [5] per the rules of the AP Computer Science Principles Reference Guide?
Answer:
The number 4 will be returned.
Explanation:
Given;
List = [0, 1, 2, 3, 4]
Using the AP Reference Guide;
The first element has an index of 1 and can be accessed using the same. i.e
=> List[1] = 0
The second element has an index of 2 and can be accessed using the same. i.e
=> List[2] = 1
Therefore, if our code tries to access List[5], then the number at index 5 will be returned. i.e
=> List[5] = 4
This implies that the last number 4 will be returned.
Note: Many programming languages (such as Java) actually start their collection (array, list) index from 0 rather than 1. But since we are using the AP Computer Science Principles Reference Guide, the index has to start from 1.

A. True
B. False
Answer:
A. True.
Explanation:
The internet or the world wide web (www) is a global network of interconnected networks. It has a wide range of dedicated servers, intermediate network devices like routers and switches, and end devices to access data.
The website is a collection of web pages hosted on web servers on the internet. Web browsers are application softwares used by end devices to request for web pages. There are two types of network connection, peer to peer and client/server connection.
The peer to peer network involves computers serving as client ( requesting for data) and server (transmit data) at the same time. The client/server network one has a dedicated server that transmits data and a client that request for data.
This makes computer running web browsers, clients to web servers on the internet.
