Layer 3 interfaces support two items from the provided options: A. NAT (Network Address Translation)
B. IPv6 (Internet Protocol version 6)These functionalities are related to routing and addressing at Layer 3 of the OSI model. On the other hand, switching and spanning tree are associated with Layer 2 (the Data Link layer).

Network Address Translation (NAT) is a computer networking technology that enables private IP address-only devices to interact with public IP address-only devices connected to the internet. NAT translates a device's local network's private IP addresses into a public IP address that may be used online. Network Address and Port Translation (NAPT) is the most used type of NAT. It converts numerous private IP addresses into a single public IP address by utilising different source port numbers for each connection. By allowing several devices to share a single public IP address, this saves address space and facilitates network traffic management.

A significant problem with priority scheduling algorithms is starvation.

Priority scheduling is a method used in operating systems to allocate CPU resources to processes based on their assigned priority levels. Processes with higher priority levels are executed before those with lower priority levels.

Starvation occurs when low-priority processes are continually denied access to the CPU because higher-priority processes are consistently being executed. This may lead to the low-priority processes never getting the chance to execute, or experiencing an excessive waiting time. This problem arises because priority scheduling algorithms tend to focus on serving higher-priority processes without considering the needs of lower-priority processes.
To mitigate starvation, one solution is to implement aging. Aging is a technique where the priority of a waiting process gradually increases over time.

This ensures that even low-priority processes will eventually get a chance to execute, as their priority level will increase and surpass that of other higher-priority processes. Another approach is to use a combination of priority scheduling with round-robin scheduling, which allocates a fixed time quantum to each process in the queue, allowing all processes to eventually execute.

In conclusion, priority scheduling algorithms can be efficient in managing CPU resources, but they can also lead to starvation for low-priority processes. Solutions such as aging or combining priority scheduling with round-robin scheduling can help alleviate this issue, ensuring that all processes have a fair chance to execute.

The worst-case complexity of adding an element to an array-based, unlimited-capacity stack that uses a shadow array is O(n) due to the need to copy all elements to a larger list when the stack is full.

An array-based stack is a data structure that allows adding and removing elements in a Last-In-First-Out (LIFO) order. The stack is implemented using an array where the elements are stored sequentially. The top of the stack is the last element added to the array.

To add an element to the top of the stack, we can simply insert it into the next available index in the array. However, if the array is already full, we cannot add the new element without making more space.

To create more space in the array, we need to resize it. Resizing the array involves creating a new array with a larger size and copying all the elements from the old array to the new one. Once the elements are copied, the new array becomes the current stack, and the old array is discarded.

The time complexity of resizing the array depends on how many elements are in the stack. If the stack has n elements, copying all of them to the new array takes O(n) time. Therefore, the worst-case complexity of adding an element to the stack is O(n) when the array is full and needs to be resized.

However, using a shadow array can improve the performance of the array-based stack. A shadow array is a separate array that is created alongside the main stack array. The shadow array is used to store a copy of the main array when it becomes full.

When a new element needs to be added to the stack and the main array is full, we can copy a fixed number of elements (for example, half of the array) to the shadow array, resize the main array, and copy the elements back to the main array. The size of the main array doubles, which reduces the frequency of resizing. Using a shadow array can reduce the time complexity of adding an element to O(1) because it allows for constant time copying of a constant number of elements to the shadow array when the stack is full. However, the worst-case complexity of the operation is still O(n) since there is always a chance that the array will become full and require resizing.

The predicate issorted is used to determine if a given list is sorted in ascending order. It takes a list as an argument and returns true if the list is sorted or false otherwise.  The issorted predicate can be used to check if any given list is sorted, as long as it contains comparable items.The predicate can be defined as follows:

def issorted(lst):
   if len(lst) <= 1:
       return True
   else:
       for i in range(len(lst) - 1):
           if lst[i] > lst[i + 1]:
               return False
       return True
The issorted predicate first checks if the length of the list is less than or equal to 1, in which case the list is sorted by default. Otherwise, it loops through the list and compares pairs of items from left to right. If the first item in a pair is greater than the second, the list is not sorted and false is returned. Otherwise, true is returned if the loop completes without finding any unsorted pairs.Here is an example of how to use the issorted predicate:
def main():
   lyst = [1, 2, 3, 4, 5]
   if issorted(lyst):
       print("List is sorted.")
   else:
       print("List is not sorted.")
Output: List is sorted.
In this example, the list [1, 2, 3, 4, 5] is passed to the issorted predicate, which returns true since the list is sorted in ascending order. The main function then prints the appropriate message to the console.

This function takes in two arrays of data in original units, calculates the slope of the line of best fit using the method described above, and returns the slope value.

To define a function slope that computes the slope of our line of best fit in original units, we can use the following steps:

1. First, we need to calculate the means of our two arrays of data using the mean function we defined previously. Let's call these means x_bar and y_bar.

2. Next, we need to calculate the deviations from the means for both arrays using the deviation function we defined previously. Let's call these deviations x_dev and y_dev.

3. Then, we need to calculate the product of the deviations for each pair of data points and sum them up. Let's call this sum xy_dev.

4. Finally, we can calculate the slope of our line of best fit by dividing the sum of the product of deviations by the sum of squared deviations of x. This can be represented as:

slope = xy_dev / (x_dev ** 2)

So, our function slope would look something like this:

def slope(x_data, y_data):
   x_bar = mean(x_data)
   y_bar = mean(y_data)
   x_dev = deviation(x_data, x_bar)
   y_dev = deviation(y_data, y_bar)
   xy_dev = sum([x*y for x, y in zip(x_dev, y_dev)])
   slope = xy_dev / (sum([x**2 for x in x_dev]))
