Answer:
A. To uniquely identify each record in the table
Explanation:
From the list of given options, the option that best describe the primary key is A.
For better understanding of what primary key is all about, I'll make use of the following illustration.
Take for instance; the following relational table fields and records
SN ----- Name ----- Age
1 ------- John ---------15
2------- Peter ------- 17
3 ----- Ruth ----------16
If I've set the primary key of the above table to be SN, this means that no two records can have the same SN because each SN value is unique to every row.
Similarly,if I've set the primary key as Name, then there can only be one occurrence of John, Ruth or Peter because each of these are unique to their rows.

A flat-panel detector is exposed with nothing between the x-ray tube and detector. 5 images were acquired on 5 different days using the same exposure. The pixel readings within a region of interest (ROI) are compared. What quality control test was performed?
a. Detectability
b. Linearity
c. Repeatability
d. Uniformity
Answer:
c. Repeatability
Explanation:
Since in the question it is mentioned that the falt panel detects the relation between the x-ray tube and detector. Also five images were purchased on five different days but used the similar exposure
So for the quality control test, the repeatability should be performed as the reading of the pixel is done within a region of interest also it examines the consistency of the pixel reading over time
Hence, the correct option is c.

Suppose that instead of swapping element A[i] with a random element from the subarray A[i..n], we swapped it with a random element from anywhere in the array: PERMUTE-WITH-ALL (A) 1, n = A.length 2, for i = 1 to n 3, swap A[i] with A[RANDOM(1, n)] Does this code produce a uniform random permutation? Why or why not?
Answer:
The answer to this question can be defined as follows:
Explanation:
Its Permute-with-all method, which doesn't result in a consistent randomized permutation. It takes into account this same permutation, which occurs while n=3. There's many 3 of each other, when the random calls, with each one of three different values returned and so, the value is= 27. Allow-with-all trying to call possible outcomes as of 3! = 6
Permutations, when a random initial permutation has been made, there will now be any possible combination 1/6 times, that is an integer number m times, where each permutation will have to occur m/27= 1/6. this condition is not fulfilled by the Integer m.
Yes, if you've got the permutation of < 1,2,3 > as well as how to find out design, in which often get the following with permute-with-all chances, which can be defined as follows:
[tex]\bold{PERMUTATION \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ PROBABILITY}[/tex]

You have an on-premises network that contains several servers. You plan to migrate all the servers to Azure. You need to recommend a solution to ensure that some of the servers are available if a single Azure data center goes offline for an extended period.
What should you include in the recommendation?
A. fault tolerance
B. elasticity
C. scalability
D. low latency
Answer:
A). Fault tolerance
Explanation:
The Microsoft Azure is described as the cloud computing service that is known for its flexibility, cost-effectiveness, and quick and easy compliance to fulfill the company's requirements.
As per the question, in order to ensure that 'some servers are available in case of a single Azure data center going offline for an increased time period', the recommendation must include the 'fault tolerance' ability of Azure services. Azure infrastructure has the ability to immediately react in case of a failure to restore the servers and its services. In case of hardware failure, crashing of hard-disks, or short-term availability problems with servers, Azure predicts and manages such failures effectively. Thus, option A is the correct answer.

Answer:
sales in spite of a small advertising budget.
Explanation:
The Duffy Design Group was able to apply vernacular design in its label design for Classico Spaghetti Sauce. Vernacular design refers to the incorporation of the indigenous attributes of a people, be it their vocabulary, history, or any other aspect of their culture in an artistic form.
The success recorded by this group was that despite the fact that this product was not widely advertised, it still received high patronage because the people were able to relate to the design. This highlights the importance of recognizing and applying local culture in design.
Given that Jamie worked 50 hours (Hours = 50) last week and earns $10.00 an hour (Rate = 10), how much did Jamie earn last week, before taxes (TotalPay)? If (Rate >=10) OR (Hours <=40) Then TotalPay = Hours * Rate Else TotalPay = (Hours * Rate)+(Hours–40)*Rate*1.5 End If
Answer:
Jamie earned (Total pay) $500.
Explanation:
We are given the following code:
If (Rate >=10) OR (Hours <=40) Then
TotalPay = Hours * Rate
Else
TotalPay = (Hours * Rate)+(Hours–40)*Rate*1.5
End If
Let us understand the code line by line:
The first line contains an if statement with 2 conditions:
i.e. 1st condition:
The rate is greater than or equal to 10
2nd condition:
Number of hours are lesser than or equal to 40.
There is OR between the two condition i.e. the statement next to if() statement will get executed if any one of them becomes true and else part will not be executed.
The next statement is:
TotalPay = Hours * Rate
It calculates the pay if any of the two conditions written earlier becomes true.
Next statement is else statement:
It will get executed given that the above if() statement becomes false.
Now, we are given that Jamie worked 50 hours last week and earns $10.00 an hour:
i.e.
Hours = 50
Rate = 10
Now, let get to the code execution.
The first condition is true i.e. Rate >= 10 (because Rate is 10 here)
So, the following statement will be used to calculate the Total pay:
TotalPay = Hours * Rate
and else part will not be executed.
TotalPay = 50 * 10 = $500
Jamie earned (Total pay) $500.

Explanation:
Write a function, sublist, that takes in a list of numbers as the parameter. In the function, use a while loop to return a sublist of the input list. The sublist should contain the same values of the original list up until it reaches the number 5 (it should not contain the number 5).
Answer:
Following are the code to this question:
def sublist(l):#defining a method list sublist that accepts a list
val=[]#defining an empty list
x=0#defining x variable that store value 0
while(x<len(l)):#defining loop that check x is lessthen list length
if(l[x]==5):#defining if block that checks list value equal to 5
break#using break keyword
val.append(l[x])#add value in val list
x+= 1#increment the value of x variable by 1
return val#return val
l=[3,4,7,8,5,3,2]#defining list l
print(sublist(l))#using print method to call sublist method
Output:
[3, 4, 7, 8]
Explanation:
In the above python code, a method "sublist" is declared that accepts a list, inside the method an empty list "val" and an integer variable x is defined that stores "0" value. In the method, a while loop is declared that checks list length and define if block to checklist element value equal to "5". which the condition is true it will return before values. In the last step, a list "l" is declared that holds value and used the print method to call sublist to prints its return value.You work in the Accounting department and have been using a network drive to post Excel workbook files to your file server as you complete them.

A Cisco Catalyst switch has been added to support the use of multiple VLANs as part of an enterprise network. The network technician finds it necessary to clear all VLAN information from the switch in order to incorporate a new network design. What should the technician do to accomplish this task
Answer:
The technician should delete the startup configuration and the "vlan.dat" file residing in the flash memory of the newly added switch and lastly, he should reboot the switch.
Explanation:
In this scenario, a Cisco Catalyst switch has been added to support the use of multiple virtual local area networks (VLANs) as part of an enterprise network. The network technician finds it necessary to clear all virtual local area network (VLAN) information from the switch in order to incorporate a new network design. To accomplish this task successfully, the technician should delete the startup configuration and the "vlan.dat" file residing in the flash memory of the newly added switch and lastly, he should reboot the switch. The VLAN informations are stored in a file with the name "vlan.dat" residing in the flash memory of the switch.
However, in order to delete the startup configuration he would be required to login as an administrator, so as to have all privileges.
Also, the essence of deleting the startup configuration and the "vlan.dat" is to avoid any conflict in the network.

For a plain text book, one byte typically corresponds to one character and an average page consists of 2000 characters. Assume all gigabytes are used for plain text books. a. How many pages of text can the tablet hold? b. How many 500-page books can the tablet hold?
Answer:
a. 17,500,000 pages
b. 35,000
Explanation:
The computation is shown below:
As we know that
[tex]1 giga\ bytes = 1 \times 10 ^ {9} bytes[/tex]
So for 35 gigabytes it would be
[tex]= 35 \times 10 ^ {9} bytes[/tex]
And it is given that there is 2,000 characters
a. So the number of text pages would be
Let us assume that
for 2,000 it would be 1 page
So for [tex]35 \times 10 ^ {9} bytes[/tex] it would be x
Now we solve the x which is equal to
[tex]= \frac {35 \times 10 ^ {9} bytes}{2,000}[/tex]
= 17,500,000 pages
b. Now for 500 pages, it would be
[tex]= \frac{17,500,000}{500}[/tex]
= 35,000
Bharath has made a table of content for his document, in which he wants to make few changes, but he is unable to make the changes. Give reason. Explain how he can make the necessary changes.
Answer:
Explanation:
Microsoft Word has an automatic table of contents function that can automatically generate a table of contents for your document, provided you correctly tag the chapter headers and sub-headers that you wish to show in your table of contents. Setting this up can be a time-consuming process, but if you are writing a lengthy document that will go through several drafts, the automatic Table of Contents can save you a lot of manual revising each time your page numbers or chapter titles change.
Step 1: In order for Word to identify the headers and subheaders for your Table of Contents, you need to apply the appropriate "Heading" styles to your chapter and sub-chapter headers.
For example, to mark a chapter title as a Level 1 Heading, first select the text that you would like to appear as the chapter heading in the Table of Contents by clicking-and-dragging your cursor over it to highlight it.
