Answer:
(A) Always true
Explanation:
Given
Boolean variables x and y
Required
What is (x && y) || !(x && y)
Irrespective of what x or y is, the x && y is always true
Take for instance:
x = true;
y = true;
x&&y will also be true because the values of x and y were not altered
And this is true for whatever boolean value x or y assume
Having said that:
x&&y = true
So, the expression is analysed as follows:
(x && y) || !(x && y)
Substitute true for x&&y
(true) || !(true)
!(true) = false
So, the expression becomes:
true || false
|| represents the OR operator; and it returns true if at least one of the conditions is true.
By this:
true || false = true
Option (A) Always true answers the question.
Cell address $A$4 in a formula means it is a ___________. *
A. All of the above
B. Mixed cell reference
C. Relative cell reference
D.Absolute cell reference
Answer:
The answer to this question is given below in the explanation section
Explanation:
Cell address $A$4 in a formula means it is an Absolute Cell Reference.
Absolute cell reference does not change when you copy the formula to other cells. when the $ symbol added in the front of the column and row, makes it absolute. It stops the row and column numbers from changing when you copy to other cells. The given $A$4 cell address contains the value in column A and row 4. It does not change the value when you copy the formula that has mentioned ($A$4) into other cells. For example, if you have value 10 at row 4 and column A. Then you multiple column B with A4 cell value and you want that A4 value will not change while copying formula from C1 to C10. You can use in column C1 as =B1*$A$4. Then you copy the formula to cell 10. The value of $A$4 will not change.
while the other options are not correct because:
In the relative cell reference values get changed in the formula, while in the mixed cell reference you can either locked the row or column while the row or column changes when the formula is copied respectively.
If an exception is thrown, it is passed to a block of code that can ____, which means to receive it in a block that can handle the problem.
Answer:
Catch the exception.
Explanation:
In Computer programming, an exception can be defined as an unprecedented error or event that occurs unexpectedly while a computer software application or program is running. Thus, when this exception occurs while a software program is running, it would affect its flow.
However, if the software program is able to handle and process unprecedented error or event that occured unexpectedly, it would continue to run but if it cannot handle it, the software program will force quit.
In Java programming language, exception class such as IOException, UserException, TimeoutException, and exception subclass such as CharacterCodingException, FileNotFoundException etc may be thrown when a software program encounters an unexpected error or event.
A software program that is properly coded or well-written is able to check for exceptions and appropriately handle the exceptions (unexpected errors) so as to prevent the software program from crashing or forced to quit.
This ultimately implies that, when an exception is thrown using a try clause or throw statement as it occurs, it is caught by a block of code in the software program.
Hence, if an exception is thrown, it is passed to a block of code that can catch the exception, which means to receive it in a block that can handle the problem.

Write a program that keeps track of a simple inventory for a store. While there are still items left in the inventory, ask the user how many items they would like to buy. Then print out how many are left in inventory after the purchase. You should use a while loop for this problem. A sample run is below.
(CodeHS, PYTHON)
Answer:
STARTING_ITEMS_IN_INVENTORY = 20
num_items = STARTING_ITEMS_IN_INVENTORY
# Enter your code here
while num_items > 0:
print("We have " + str(num_items) + " items in inventory")
toBuy = int(input("How many would you like to buy?"))
if toBuy > num_items:
print("There is not enough in inventory")
print("Now we have " + str(num_items) + " left")
else: # ok to sell
num_items = num_items - toBuy # update
if num_items > 0: # only for printing
print("Now we have " + str(num_items) + " left")
print("All out!")
Explanation:
This allows Python to store the number of items in inventory after each purchase by subtracting how much is bought with the toBuy function by how much is left. This continues until num_items is no longer greater than zero. If what’s toBuy goes above the # of items left in inventory, then the “if toBuy > num_items” segment of the code comes into play by telling the user there’s not enough and re telling them how much is left and how much they’d like to buy. When the items in inventory is out, meaning the exact amount that’s left is purchased, then Python prints “All out!”
Following are the code to the given question:
Program Explanation:
Defining a variable "INVENTORY_ITEMS" that hold an integer value.Defining a variable "num" that holds "INVENTORY_ITEMS" value.In the next step, a while loop is declared that checks "num" value greater than 0.Inside the loop, "num and To_Buy" is declared and in the To_Buy it inputs value by user-end.In the next step, conditional statement is used that check "To_Buy" value and prints its value.At the last another conditional statement is used that checks num value, and print its value.Program:
INVENTORY_ITEMS = 20#defining a variable INVENTORY_ITEMS that hold integer value
num= INVENTORY_ITEMS#defining a num variable that holds INVENTORY_ITEMS value
while num > 0:#defining a while loop that check num value greater than 0
print("We have " + str(num) + " items in inventory")#print num value with message
To_Buy = int(input("How many would you like to buy?"))#defining To_Buy variable that inputs value
if To_Buy > num:#defining if block that check To_Buy value greater than num value
print("There is not enough in inventory")#print message
print("Now we have " + str(num) + " left")#print num value with message
else: # defining else block
num= num - To_Buy#using num variable that decreases num by To_Buy
if num> 0: #use if to check num greater than 0
print("Now we have " + str(num) + " left")#print num value with message
print("All out!")#print message

Taylor and Rory are hosting a party. They sent out invitations, and each one collected responses into dictionaries, with names of their friends and how many guests each friend is bringing. Each dictionary is a partial list, but Rory's list has more current information about the number of guests. Fill in the blanks to combine both dictionaries into one, with each friend listed only once, and the number of guests from Rory's dictionary taking precedence, if a name is included in both dictionaries. Then print the resulting dictionary.
Answer:
Following are the code to this question:
def combine_guest(guest1, guest2):#defining a method combine_guest that accepts two dictionary
guest2.update (guest1)#use dictionary guest2 that use update method to update guest2 dictionary
return guest2#return guest2 dictionary values
Rory_guest= { "Ada":2, "Ben":3, "Dav":1, "Jo":3, "Charry":2, "Terry":1, "bob":4}#defining a dictionary and add value
Taylor_guest = { "Dav":4, "Nan":1, "bobert":2, "Ada":1, "Samantha":3, "Chr":5}#defining a dictionary and add value
print(combine_guest(Rory_guest,Taylor_guest))#calling the combine_guest method
Output:
{'Nan': 1, 'Samantha': 3, 'Ada': 2, 'bob': 4, 'Terry': 1, 'Jo': 3, 'Ben': 3, 'Dav': 1, 'Charry': 2, 'bobert': 2, 'Chr': 5}
Explanation:
In the code a method, "combine_guest" is defined, that accepts two dictionaries "guest1, guest2" inside the method, in which the "guest2" dictionary uses the update method to combine the value of the guest1 dictionary and use a return keyword to return guest2 values.
In the next step, two dictionaries are declared, that holds some values and use a print method to call the "combine_guest" method and prints its return values.

What is the value stored at x, given the statements:
int x;
x=3/(int)(4.5+6.4)
a. 0.3
b. 0
c. .275229
d. 3.3
e. None of these
Answer:
0.
Explanation:
Given
int x;
x=3/(int)(4.5+6.4)
Required
What is x?
The first line of the code segment declares x as integer. This means that, it will only hold non decimal numbers.
With the above explanation, options (a), (c) and (d) can not be true.
Solving further:
x=3/(int)(4.5+6.4)
The computer evaluates the denominator as:
x=3/(int)(10.9)
The denominator is then converted to an integer. So, we have:
x = 3/10;
3/10 = 0.3 but
Recall that: x will only hold non decimal numbers.
So:
x = 0;
Consider the code block below. What is the value of amount when this method is called twice, the first time using cookieJar(7) and then using cookieJar(22)?
public static int cookieJar(int addCookies) {
int amount = 0;
amount += addCookies;
return amount;
}
A. 7
B. 15
C. 22
D. 29
E. An error occurs
Answer:
C. 22
Explanation:
Given that the argument is being passed by value, there is no memory to consider. So cookieJar(7) returns 7 and cookieJar(22) returns 22.
If the argument parameter was passed by reference or pointer, then perhaps the value from cookieJar(7) would be considered with cookieJar(22).
Note, this code block really isn't doing anything other than returning the value passed into it. The "amount" variable is immediately set to 0, and then the value passed in is added to amount (which is 0), and returns. The following code could replace this function:
public static int cookieJar(int addCookies){
return addCookies;
}
The above code will return an equivalent output to the given code.
Notice, the function is not dependent on any previous call, so the value for each is unique to the call itself, i.e., cookieJar(22) returns 22 and cookieJar(7) returns 7.
So, C. 22 would be correct.

Explanation:
The following program is suppose to use the sin() function in the math library and write out an input's absolute value over an interval. So for example if sine(0.6) is 0.564 then its absolute value is the same (0.564). But if sine(2.4) is -0.675 then its absolute value is 0.675. #include #include /* has sin(), abs(), and fabs() */ int main(void) { double interval; int i; for(i = 0; i <30; i++) { interval = i/10.0; printf("sin( %lf ) = %lf \t", interval, abs(sin(interval))); } printf("\n+++++++\n"); return 0; }
Answer:
#include <stdio.h>
#include <math.h> /* has sin(), abs(), and fabs() */
int main(void) {
double interval;
int i;
for(i = 0; i <30; i++) {
interval = i/10.0;
printf("sin( %.1lf ) = %.3lf \t", interval, abs(sin(interval)));
}
printf("\n+++++++\n");
return 0;
}
Explanation:
The C source code defines a void main program that outputs the absolute value of the sine() function of numbers 0.1 to 3.0.
The program is an illustration of loops.
Loops are used to perform repetitive and iterative operations.
The program statements in C language that completes the program are as follows:
interval = i/10.0;
printf("sin( %.1lf ) = %.3lf \t", interval, abs(sin(interval)));
The flow of the above statements is as follows
The first line determines the intervalThe second line prints the required output

The output for the program will be 50 with error statement is 0.50.
What is program?Program is defined as a collection of guidelines that a computer follows to carry out a certain task. Low-level access to system memory is made possible by the procedural and general-purpose nature of the C programming language. To create an executable that a computer can run, a C program needs to be run through a C compiler. A computer programmer can write lines of code that the computer can understand by utilizing a programming language to develop a program.
A & B and the variable a & b are distinct. Thus, the #main program is the only program that functions.
As a result, A = 5 and B = 10, and the answer is
A x B, which equals 5 x 10 = 50.
Thus, the output for the program will be 50 with error statement is 0.50.

You are running your warehouse using Autonomous Data Warehouse (ADW) service and you noticed that a newly configured batch job is always running in serial even through nothing else is running in the database. All your jobs are configured to run with parallelism enabled.What could be the reason for this batch job to run in serial?A. The batch job depends on only one table and parallelism cannot be enabled on single-table queries.B. The parallelism of batch job depends on the number of ADW databases involved in the queryC. The new batch job is connected to LOW consumer group.D. The new batch job runs on database tables that are not enable for parallel execution.E. Parallelism on the database is controlled by the application, not the database.
Answer:
C. The new batch job is connected to the LOW consumer group.
Explanation:
Remember, one of the main characteristics of the LOW consumer group database service is that queries would run serially.
Since in this case, we are told that the newly configured batch job is always running in serial, it most likely would be because the new batch job is connected to the LOW consumer group; as queries are designed to always run serially.

Can race condition happen in monolithic memcached.
a. True
b. False
Answer:
True
Explanation:
It is TRUE that race condition happens in monolithic Memcached. This is evident in that in a python language, where Memcached "gets" and "set" function tends to turn to a race condition if for example the two functions are used together to accomplish similar things like locking given that it is not atomic.
Hence, in this case, the correct answer is TRUE
It should be noted that a race condition cannot occur in monolithic memcached. Therefore, it's false.
A race condition simply means when two threads are able to access a shared variable at a particular time.
In such a case, the first thread and the second thread will perform their operations on the value and they'll race in order to see the thread that can write the value last row of the variable that's shared. A race condition
cannot occur in monolithic memcached. Therefore, it's false.

A buffer in computer technology can be defined as a temporary area set aside for data storage. Buffers reside in the random access memory (RAM). In the event that, a system process or program places more data (much more than what was originally or initially intended to be allocated for data storage) in a buffer, the extra data overflows. Consequently, this would result in having some of the data to flow into other buffers and thus, causing the data to be overwritten or corruption of the data being held in that buffer.
For instance, we can liken a buffer-overflow to pouring water (data) into a container (program memory), once it is filled the water begins to overflow as the container has reached its maximum amount.
Your company is designing a multi-tenant application that will use elastic pools and Azure SQL databases. The application will be used by 30 customers.
You need to design a storage solution for the application. The solution must meet the following requirements:
✑ Operational costs must be minimized.
✑ All customers must have their own database.
✑ The customer databases will be in one of the following three Azure regions: East US, North Europe, or South Africa North.
What is the minimum number of elastic pools and Azure SQL Database servers required?
Answer:
The minimum number of elastic pools and Azure SQL Database servers required is:
three elastic pools and one Azure SQL Database server.
Explanation:
The above will ensure that the Azure regions of East US, North Europe, or South Africa North are grouped into their three elastic pools. Since cost minimization must be achieved, at the same time, one Azure SQL Database server will be enough to manage the 30 databases required, with one for each customer. Creating more than one Database server will increase the operational costs.
