The action to take is to:
Delete the .(root) zone from the DNS2. Then configure conditional forwarding on the DNS2 server. If this is not done, the users will be unable to access the internet.
Explanation:
DNS forwarding enables DNS queries to be forwarded to a designated server, say DNS2, for resolution according to the DNS domain name. This stops the initial server, DNS1, that was contacted by the client from handling the query, thereby improving the network's performance and resilience and enabling the users to be connected to the DNS2 in order to access the internet.

If we are transferring data from a mobile device to a desktop and receive an error message that the mobile device has stopped communicating with the desktop, what is most likely the root cause?
a. the physical head on the cable os not the correct type
b. one of the ports on either device is damaged or under powered
c. the computer is not running the correct application
d. cable is not the correct color
Answer should probably be B. I don’t think you’d need an application to transfer data, and the computer wouldn’t even tell you if the data couldn’t transfer if you have the wrong cable head. It wouldn’t even be connected.
The root cause at the time when transferring the data from mobile device to the computer is that the port on the device is either damaged or it is underpowered.
The following are not the root causes for the error message at the time of transferring the data from a mobile device to the computer:
The cable is not of accurate type.The computer does not run the right application.The cable is not of accurate color.Therefore we can conclude that the root cause at the time when transferring the data from a mobile device to the computer is that the port on the device is either damaged or it is underpowered.

Suppose a program written in language L1 must be executed on a machine running a program running in language L0. What important operation must take place
Question Completion with Options:
a. Translation of the entire L1 program into L0 code
b. Translation of the L0 program into L1 code
c. Creation of a language L3 that interprets L0 instructions
d. Interpretation of each L1 statement using L0 code as the L1 program is running.
Answer:
The important operations that must take place in this scenario are:
a. Translation of the entire L1 program into L0 code
d. Interpretation of each L1 statement using L0 code as the L1 program is running.
Explanation:
Translation enables decoding to take place. This means that the L1 program is decoded into a language that the L0 program can understand and execute. Without this translation, the higher level language of L1 will not be understood by the machine language of the L0 programs. Translation of a code creates a shared understanding, thereby easing program execution. Code translation is simultaneously accompanied by interpretation.

Page scaling mode helps increase or reduce the size of the worksheet to fit within the set number of pages to be printed. Which option re-scales
a worksheet vertically?
To re-scale a worksheet vertically, select the number of pages in the height text box in the____group.
Answer:
Scale to fit.
Explanation:
The scale to fit group can be found in the page layout tab as it is used to deal with display of functionalities of a document and spreadsheet program. The scale to fit requires input in the width option which will dictate the width of the page in which to place the documents on. By specifying 1 for the width, this means that the document will be rescaled to fit on a single page. The automatic option may be selected for the height option which will allow the program to make an auto Decison in the shrinkage depending on the stated width value.

What coding technique is illustrated by the following code? PayCalculator calc; double pay = calc.calculate_wages(40, 20.5).get_wages(); a. self-referencing b. function chaining c. dereferencing d. class chaining
Answer:
The answer is "Option b".
Explanation:
Function chaining is shown by this code, as the functions are called one after the other with one statement. Whenever you want to call a series of methods through an object, that technique is beneficial. Just because of that, you may give the same effect with less code and have a single given value only at top of the leash of operations.

Chip creep can be described as a problem that arises as a chip or integrated circuit works its way out of its sockets as Time goes on. it is also the gradual loosening of the integrated circuit. This problem was quite common during early PCs.
What causes this is changes in temperature. Known as thermal expansion. During thermal expansion, as the system gets heated up and during the process of it cooling down it could occur.
Given a sorted list of integers, output the middle integer. A negative number indicates the end of the input (the negative number is not a part of the sorted list). Assume the number of integers is always odd. Ex: If the input is:
Answer:
The program in Python is as follows:
myList = []
num = int(input())
count = 0
while num>=0:
myList.append(num)
count+=1
num = int(input())
myList.sort()
mid = int((count-1)/2)
print(myList[mid])
Explanation:
This initializes the list
myList = []
This gets the first input
num = int(input())
This initializes count to 0
count = 0
The following is repeated until the user inputs a negative number
while num>=0:
This appends the input number to the list
myList.append(num)
This increments count by 1
count+=1
This gets another input
num = int(input())
This sorts the list
myList.sort()
Assume the number of inputs is odd, the middle element is calculated as
mid = int((count-1)/2)
This prints the middle element
print(myList[mid])

In the context of the components of a typical expert system, _____ is similar to a database, but in addition to storing facts and figures it keeps track of rules and explanations associated with facts.
Answer:
Knowledge base.
Explanation:
Artificial intelligence (AI) also known as machine learning can be defined as a branch of computer science which typically involves the process of using algorithms to build a smart computer-controlled robot or machine that is capable of performing tasks that are exclusively designed to be performed by humans or with human intelligence.
Artificial intelligence (AI) provides smarter results and performs related tasks excellently when compared with applications that are built using conventional programming.
Generally, there are two (2) main characteristics of artificial intelligence (AI) systems and these include;
I. Non-algorithmic processing.
II. Symbolic processing.
In artificial intelligence (AI), the field of expert systems is the most important applied area because it models human knowledge.
Hence, expert systems represents knowledge as a set of rules by mimicking the expertise of humans in a particular field to uniquely proffer solutions to a problem.
Although, all expert systems are generally lacking in human capabilities and can only use inference procedures to proffer solutions to specific problems that would normally require human expertise or competence.
Some of the areas where expert systems can be applied are; monitoring, diagnosis, scheduling, classification, design, process control, planning, etc.
Basically, expert systems comprises five (5) main components and these are;
1. Explanation module.
2. Inference Engine.
3. Knowledge acquisition and learning module.
4. User Interface.
5. Knowledge Base.
In the context of the components that makes up an expert system, knowledge base is similar to a database because it is used for storing facts and figures, while keeping track of rules and explanations associated with facts. Thus, giving rise to the knowledge base management system (KBMS).
In the context of the components of a typical expert system, Knowledge base is similar to a database, but in addition to storing facts and figures, it keeps track of rules and explanations associated with facts.
An expert system is a form of artificial intelligence where computer imitate the decision making style of humans.
There are basically two types of the expert system and they are the inference engine and the knowledge base.
The knowledge base consists of the facts and rules and ways of interpreting them to arise to new insights. The inference engine applies logical rules to the knowledge base.

Answer:
The program is as follows:
n = int(input("List elements: "))
mylist = []; myList2 = []
for i in range(n):
num = int(input(": "))
mylist.append(num)
for i in mylist:
if i >= 0:
myList2.append(i)
for i in mylist:
if i < 0:
myList2.append(i)

Explanation:
This gets the number of list elements from the user
n = int(input("List elements: "))
This initializes two lists; one of input and the other for output
mylist = []; myList2 = []
This is repeated for every input
for i in range(n):
Get input from the user
num = int(input(": "))
Append input to list
mylist.append(num)
This iterates through the input lists
for i in mylist:
If list element is non-negative
if i >= 0:
Append element to the output list
myList2.append(i)
This iterates through the input lists, again
for i in mylist:
If list element is negative
if i < 0:
Append element to the output list

Answer:
"In inner for loop" is printed twice.
Answer: C. 2
Explanation:
Code:
int main()
{
int limit = 0;
for (int i =0; i>=limit; i-=2) {
for (int j = i; j <= 1; ++j){
cout << "In inner for loop" << endl;
}
cout << "In outer for loop" << endl;
}
return 0;
}
Output:
In inner for loop
In inner for loop
In outer for loop
The output "In inner for loop" print twice.
Thus, option (c) is correct.
In the given code example, the inner for loop has a condition j <= 1.
This condition means that the loop will execute as long as j is less than or equal to 1.
However, the initial value of j is i, and the value of i decreases by 2 in each iteration of the outer for loop.
When i = 8, the inner loop has the condition j ≤ 1.
The loop will iterate as long as j is less than or equal to 1.
So the inner loop executes twice: once when j = 8, and then when j = 9. The statement "In inner for loop" prints twice.
Therefore, the output print twice.
Thus, option (c) is correct.

A.) Have a shared database that allows both
applications to read and write to the tables to share the data instead of having to communicate
B.) Use asynchronous messaging to send and receive messages between each microservice
C.) Abandon the microservice architecture so no interaction is needed
D.) Create a third service to handle the interaction between the services
E.) Use a RESTful architecture for both, send the ID through a POST, and ping the service with a GET until a response is available
Answer: E. Use a RESTful architecture for both, send the ID through a POST, and ping the service with a GET until a response is available.
Explanation:
Since there are two microservices that need to communicate with each other without holding up a thread on either end, the communication framework should be used is a RESTful architecture for both, send the ID through a POST, and ping the service with a GET until a response is available.

Write a program that uses linear recursion to generate a copy of an original collection in which the copy contains duplicates of every item in the original collection. Using linear recursion, implement a function that takes a list as user-supplied runtime input and returns a copy of it in which every list item has been duplicated. Given an empty list the function returns the base case of an empty list.
Answer: b
Explanation:
Program using linear recursion to duplicate items in a list:
def duplicate_list(lst):
if not lst:
return []
else:
return [lst[0], lst[0]] + duplicate_list(lst[1:])
# Example usage
user_input = input("Enter a list of items: ").split()
original_list = [item for item in user_input]
duplicated_list = duplicate_list(original_list)
print("Duplicated list:", duplicated_list)
How can a program use linear recursion to duplicate items in a list?By implementing a function that utilizes linear recursion, we can create a copy of an original list with duplicated items. The function duplicate_list takes a list lst as input and checks if it is empty. If the list is empty, it returns an empty list as the base case.
Otherwise, it combines the first item of the list with itself and recursively calls the function with the remaining items (lst[1:]). The duplicated items are added to the resulting list. This process continues until all items in the original list have been duplicated and the duplicated list is returned.

Suppose you have a stack ADT (i.e., an Abstract Data Type that includes operations to maintain a stack. Design a flowchart or suitable logical diagram to show you could implement a queue’s enqueue and dequeue operations using two stacks, stack 1 and stack 2.
Answer:
One approach would be to move all items from stack1 to stack2 (effectively reversing the items), then pop the top item from stack2 and then put them back.
Assume you use stack1 for enqueueing. So enqueue(x) = stack1.push(x).
Dequeueing would be:
- For all items in stack1: pop them from stack1 and push them in stack 2.
- Pop one item from stack2, which will be your dequeue result
- For all items in stack2: pop them from stack2 and push them in stack 1.
Hope it makes sense. I'm sure you can draw a diagram.
