Brandon has configured one of the applications hosted on his cloud service provider to increase the number of resources as needed. Which of the following describes this capability?

a. Continuity
b. Adaptability
c. Vertical scaling
d. Horizontal scaling

Answers

Answer:

The description of this capability is:

d. Horizontal scaling

Explanation:

The capability that Brandon has achieved is horizontal scaling, which involves the increasing of the resources of cloud applications to meet his increasing demand for cloud services.  Vertical scaling involves the addition or subtraction of power to a cloud server, which practically upgrades the memory, storage, or processing power.  But to scale horizontally, more resources are added or subtracted.  The purpose of horizontal scaling is to spread out or in the workload of existing resources and either increase or decrease overall performance and capacity.

The enhanced for loop _____ Group of answer choices reduces the number of iterations necessary to visit all elements of an array prevents incorrectly accessing elements outside of an array's range can be used to replace any regular for loop while yielding less code creates a copy of an existing array and iterates through the copy's elements

Answers

Answer:

prevents incorrectly accessing elements outside of an array's range.

Explanation:

The enhanced for loop prevents incorrectly accessing elements outside of an array's range. This type of loop is also called a For Each Loop. This is because this loop automatically loops through each element in the given array and grabs that element, then it performs whatever instructions are inside of the loop's body to that element before moving on to the next available element. This way there is no numbered indexing that needs to be provided and therefore prevents the loop from accidentally trying to access an index that does not exist in the array.

A year in the modern Gregorian Calendar consists of 365 days. In reality, the earth takes longer to rotate around the sun. To account for the difference in time, every 4 years, a leap year takes place. A leap year is when a year has 366 days: An extra day, February 29th. The requirements for a given year to be a leap year are:
1) If the year is evenly divisible by 4, go to step 2. Otherwise, go to step 5.
2) If the year is evenly divisible by 100, go to step 3. Otherwise, go to step 4.
3) If the year is evenly divisible by 400, go to step 4. Otherwise, go to step 5.
4) The year is a leap year (it has 366 days).
5) The year is not a leap year (it has 365 days).
Some example leap years are 1600, 1712, and 2016.
Write a program that takes in a year and determines whether that year is a leap year.

Answers

Answer:

The program in Python is as follows:

year = int(input("Year: "))

print(year,end=" ")

if (year % 4) == 0:

  if (year % 100) == 0:

      if (year % 400) == 0:

          print("is a leap year")

      else:

          print("is not a leap year")

  else:

      print("is a leap year")

else:

  print("is not a leap year")

Explanation:

This gets input for year

year = int(input("Year: "))

This prints the year, input by the user

print(year,end=" ")

Check if year is divisible by 4 --- step 1

if (year % 4) == 0:

If step 1 is true, check if year is divisible by 100 -- step 2

  if (year % 100) == 0:

If step 2 is true, check if year is divisible by 400 -- step 3

      if (year % 400) == 0:

If yes, print leap year --- step 4

          print("is a leap year")

      else:

If otherwise, print not leap year --- step 5

          print("is not a leap year")

If step 3 is not true, print leap year

  else:

      print("is a leap year")

If step 1 is not true, print not leap year

else:

  print("is not a leap year")

b. The IP address of the server the process is typically accessing has changed

Explanation:

IP address stands for Internet Protocol address. It refers to a numerical value which is assigned to a every device which is connected to a computer network using the internet protocol for any communication.

Every device is allotted a unique IP address number.

In the context, Keely who works on an automation tool suddenly gets an error message that the account has been locked. This is mainly due to the changed in the IP address of the server that accesses the process.

The account gets closed or clocked whenever the IP address of the server changes.

Therefore, the correct option is (b).

The solution to this question lies in the question itself.

From the question, we are to check for

....employees that are continuous in work or not depending on age

Notice that the question does not imply the usage of an if-function but, the usage of an or function as indicated by the text in bold.

So.

If an employee is continuous in work, the function will return true

If an employee does not depend on age limit, the function will return true

The function will return false, if both conditions are not true

What happens when a dataset includes records with missing data?

Answers

Answer:

However, if the dataset is relatively small, every data point counts. In these situations, a missing data point means loss of valuable information. In any case, generally missing data creates imbalanced observations, cause biased estimates, and in extreme cases, can even lead to invalid conclusions.

It makes data analysis to be more ambiguous and more difficult.

Missing data is simply the same as saying that there are values and information that are unavailable. This could be due to missing files or unavailable information.

A dataset set with missing data means more work for the analyst. There needs to be a transformation in those fields before the dataset can be used.

Generally speaking missing data could lead to bias in the estimation of data.

In our discussion of Computer Hardware, we talked about three essential hardware components that are there inside every computer. Name them and explain the significance of each in the working of the computer. Why is a 64 bit processor better than a 32 bit processor

Answers

Answer:

CPU, RAM, and Storage

Explanation:

The three hardware components that are inside every computer and are essential for it to function are CPU, RAM, and Storage (HDD, SSD). CPU is basically the brain of the computer where everything is calculated. The RAM is the memory that stores temporary information. Lastly, the Storage device is where the entire operating system and persistent data will be saved and accessed from. 64-bit processors are better simply because they can access more memory at any given time and therefore allows it to manipulate more data at the same time.

Leo is planning the new backup strategy for a subsidiary his company is purchasing that does not currently have a backup strategy in place. He decides that a full backup should be run once per week. Once per day, everything that has changed since the last full backup will be archived. Once per hour everything that has changed since the last backup of any type will be backed up. Which of the following describes the backups that will be run every hour?

a. Differential
b. Variable
c. Incremental
d. Flexible

Answers

Answer:

C. Incremental backup

Explanation:

An incremental backup is a type of backup where the succeeding copies of the data is made up of only those positions that have changed since the previous or prior copies were made. Such backups are desired since they limit the usage of space for storage and these types of back ups are faster to do that the differential backup.

When we bring this explanation to this question, we can easily see that the backup that is being carried out is done on everything that has changed since the last backup (previous backup). Therefore this is an incremental backup.
