Final answer:
To troubleshoot the DNS issue, first ping the CorpWeb server by name and then by IP. If only the name fails, create the correct DNS A record. Verify the solution with a final ping.
Explanation:
The inability to contact the CorpWeb server possibly indicates a DNS resolution issue. Here's how to troubleshoot and fix the problem:
Ping the CorpWeb server by its full name. If there is no response, this suggests a DNS resolution problem.
Ping the CorpWeb server by its IP address (192.168.0.15). If this is successful, it confirms that the issue lies with DNS rather than connectivity.
Create or correct the A record for CorpWeb in the DNS server. The A record should point the server's fully qualified domain name (FQDN) to its IP address.
Use the ping command again to verify that the DNS problem has been resolved and that CorpWeb.CorpNet.local now responds.
Final answer:
The issue with contacting the CorpWeb server can be addressed by checking DNS resolution through pinging the server by name and by IP address. A corrective action is to verify and create the necessary A record in DNS. Once the record is set, a successful ping by server name confirms resolution of the issue.
Explanation:
To address the issue where users are unable to contact the CorpWeb server, follow these troubleshooting steps:
Ping the CorpWeb server using its full name (CorpWeb.CorpNet.local). If the ping fails, it indicates that there may be a DNS resolution issue.
Ping the CorpWeb server using its IP address (192.168.0.15). If this ping is successful, it further confirms that there is a DNS problem, since the server is reachable by its IP address but not by its full name.
To fix the issue, log into the DNS management console on CorpDC and create or correct the A record for CorpWeb.CorpNet.local to point to the correct IP address, which is 192.168.0.15.
Finally, use the Ping command again to verify that the problem has been fixed. If the ping to CorpWeb.CorpNet.local is successful, then users should now be able to contact the CorpWeb server by its full name.

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.

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.
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.The design strategy that starts with a global view of the entire problem and breaks the problem down into smaller, more manageable subproblems is known as what type of design?

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.
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.

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])

When people use Web browser software to become part of the Web, their computers become Web client computers on a worldwide client/server network.
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.
When working with arrays, most programming languages perform ________, which means they do not allow programs to use invalid subscripts. Group of answer choices
1. buffer overrun protection
2. None of these
3. bitwise data execution
4. array bounds checking subscript binding
Final answer:
In array operations, most programming languages use array bounds checking to prevent the use of invalid subscripts, ensuring memory safety.
Explanation:
When working with arrays, most programming languages perform array bounds checking, which means they do not allow programs to use invalid subscripts. The correct answer is option 4. Array bounds checking is a safety feature in many programming languages that prevents programs from accessing memory locations outside of the allocated array space.
This is important to prevent errors and potential vulnerabilities like buffer overruns, where an attacker could manipulate the program to execute arbitrary code by overwriting parts of the memory.

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.
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
