Answer:
log-based metrics
Explanation:
Log-based metrics allow you to collect and analyze data from log files, such as application logs and web server logs, to gain insights into the performance and behavior of your Azure App Service web app. These metrics can include information such as request and response times, error rates, and user behavior. This data can be used to support the development of a dashboard and near-real-time alerts for the web app, by providing detailed information about the performance and usage of the app. Additionally, log-based metrics can be queried and analyzed using Azure Monitor Log Analytics, which provides a powerful and flexible query language for extracting insights from log data.
Assume that the list of numbers nums has more than 10 elements. The program below is intended to compute
and display the sum of the first 10 elements of nums.
Line 1: i ← 1
Line 2: sum ← 0
Line 3: REPEAT UNTIL (i > 10)
Line 4: {
Line 5: i ← i+1
Line 6: sum ← sum + nums[i]
Line 7: }
Line 8: DISPLAY (sum)
This program has an off-by-one error in the indexing of the nums list.
How to identify the error?On line 6, nums[i] should be nums[i-1] since the indices of a list in most programming languages start from 0.
As a result, the program will sum the wrong elements in the nums list, and display an incorrect value for the sum.
To correct the off-by-one error, line 6 should be changed from:
sum ← sum + nums[i]
to:
sum ← sum + nums[i-1]
This way, the program will correctly access the elements of the nums list and compute the sum of the first 10 elements.

You need to configure access.
Which service principal type should you use?
Select only one answer.
system-assigned managed identity
user-assigned managed identity

Note that given that you develop and deploy an API to Azure App Service, and the API must access an Azure Blob Storage container that is secured by Azure Active Directory (Azure AD). Access to the Azure Blob Storage container must be automatically removed once the container is deleted. If you need to configure access, note that the service principal type you need to use is: "user-assigned managed identity" (Option B)
What is user-assigned managed identity?Another resource that occurs within a resource group is a user-assigned identity. This is helpful since deleting the resource group deletes the identity as well. A service principal or app registration, on the other hand, must be administered individually.

In this task, we will be finding a possible solution to number puzzles like 'SAVE' + 'MORE' = 'MONEY'. Each alphabet represents a digit. You are required to implement a function addition_puzzle that returns a dictionary containing alphabet-digit mappings that satisfy the equation. Note that if there are multiple solutions, you can return any valid solution. If there is no solution, then your function should return False.
>>> addition_puzzle('ANT', 'MAN', 'COOL')
{'A': 8, 'C': 1, 'L': 9, 'M': 6, 'N': 7, 'O': 5, 'T': 2}
>>> addition_puzzle('AB', 'CD', 'E')
False
Explanations:
ANT + MAN = COOL: 872 + 687 = 1559
AB + CD = E: The sum of two 2-digit numbers must be at least a two-digit number.
Your solution needs to satisfy 2 conditions:
The leftmost letter cannot be zero in any word.
There must be a one-to-one mapping between letters and digits. In other words, if you choose the digit 6 for the letter M, then all of the M's in the puzzle must be 6 and no other letter can be a 6.
addition_puzzle takes in at least 3 arguments. The last argument is the sum of all the previous arguments.
Note: The test cases are small enough, don't worry too much about whether or not your code will run within the time limit.
def addition_puzzle(*args):
pass # your code here
Below is one possible implementation of the addition_puzzle function:
def addition_puzzle(*args):
letters = set("".join(args))
digits = set(range(10))
mapping = {}
def is_valid(mapping):
for i, word in enumerate(args[:-1]):
num = 0
for c in word:
if c not in mapping:
return False
num = num * 10 + mapping[c]
if num == 0 or (len(str(num)) < len(word) and num <= 9):
return False
if i == 0:
sum_num = num
else:
sum_num += num
for c in args[-1]:
if c not in mapping:
return False
return sum_num == int("".join(str(mapping[c]) for c in args[-1]))
def backtrack(remaining_letters):
if not remaining_letters:
if is_valid(mapping):
return mapping
else:
return False
for c in remaining_letters:
for d in digits:
if c not in mapping and d != 0:
mapping[c] = d
result = backtrack(remaining_letters - {c})
if result:
return result
del mapping[c]
return False
return backtrack(letters)
What is the function about?This function first creates a set of all the letters used in the input words, and a set of all the possible digits (0-9). It then defines two helper functions: is_valid, which checks if the current mapping of letters to digits satisfies the equation, and backtrack, which is a recursive function that iterates through all possible mappings of letters to digits, and returns a valid mapping if one is found, or False if none is found.
The backtrack function starts by iterating through all letters in the set of remaining letters, and for each letter, it iterates through all possible digits. If the letter has not been mapped to a digit yet, and the digit is not zero, it assigns the digit to the letter, and calls itself recursively with the remaining letters.
Therefore, If the recursive call returns a valid mapping, the function returns it, otherwise, it backtracks and tries the next digit. If no valid mapping is found, the function returns False.
Note that, this solution is a backtracking solution and it will take a lot of time to solve the big inputs and also it is not very efficient.

Write a java program that takes as input an integer below 100, then prints the Fibonacci of this number.
Fibo(n)= n*(n-1)*(n-2)*…..2*1.
Java program:
import java.util.Scanner;
public class Fibonacci {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter an integer below 100: ");
int n = input.nextInt();
int fibo = 1;
for (int i = n; i > 1; i--) {
fibo *= i;
}
System.out.println("The Fibonacci of " + n + " is " + fibo);
}
}
In this program, the user is prompted to enter an integer below 100 using the Scanner class. The input is then stored in the variable "n". A for loop is used to calculate the Fibonacci of the input number by iterating from the input number to 1, and multiply each number. The final result is stored in the variable "fibo" and is printed out.
Please note that the program you provided calculates the factorial of the input number and not the Fibonacci number. fibo(n) = n*(n-1)(n-2).....2*1 is the mathematical representation for the factorial of the number n.
If you want to calculate the Fibonacci number of the input, it should be:
import java.util.Scanner;
public class Fibonacci {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter an integer below 100: ");
int n = input.nextInt();
int fibo1 = 0, fibo2 = 1, fibonacci = 0;
for (int i = 1; i <= n; i++) {
fibonacci = fibo1 + fibo2;
fibo1 = fibo2;
fibo2 = fibonacci;
}
System.out.println("The Fibonacci of " + n + " is " + fibonacci);
}
}
In this program, it uses the fibonacci series algorithm to calculate the Fibonacci of the input number.
Please keep in mind that this is just one example of a program to calculate the Fibonacci of a number, and there are many other ways to write this program depending on the requirements.

Answer:
Explanation:
One way an agile team can follow Principle 3 and 7 of the Agile Manifesto is by breaking down their software development process into time-boxed sprints. A sprint is a set period of time (usually between 1 and 4 weeks) where the team focuses on completing a set amount of work. At the end of each sprint, the team delivers a working, tested version of the software that can be used by the customer. This allows the team to continuously deliver working software every few weeks, which allows them to get feedback from the customer and make improvements as needed.

The opposite of a data-driven process is to make decisions based solely on speculation. For data-driven business leaders, listening to their gut may be part of their decision-making process, but they only take specific actions based on what the data reveals.
Business leaders in data-driven organizations understand the benefits of relying on data insights to make wise business moves. As MicroStrategy reports based on results from a McKinsey Global Institute study, data-driven businesses are 20-plus times more likely to acquire new customers and six times more likely to keep them. Those leaders, however, must be able to rely on knowledgeable data professionals and technology tools that can uncover the value in the data. Data professionals can also provide insights into the best ways to collect, store, analyze and protect valuable business data.

Scenario: In the Lecture we simulated the simple example of a Process
reading a file and then writing back to it. Now, imagine the scenario, with
two Process trying to read or write to the same file.
Task(s):
1. Try to implement any form of locking mechanism of your choice, so
that the file is not written to while another Process is writing to it, and
vice versa
To implement a locking mechanism for a file in a scenario where two processes are trying to read or write to the same file, one approach is to use a file lock. A file lock is a mechanism that allows a process to lock a file, preventing other processes from accessing it until the lock is released.
Below is an example of how you could implement a file lock using the fs module:
const fs = require('fs');
let filePath = 'example.txt';
let fd;
try {
// Open the file and set an exclusive lock
fd = fs.openSync(filePath, 'r+');
fs.flockSync(fd, 'ex');
// Read the file contents
let data = fs.readFileSync(filePath, 'utf8');
// Modify the file contents
data = data + '\nAdded new line';
// Write the modified data back to the file
fs.writeFileSync(filePath, data, 'utf8');
} catch (err) {
console.error(err);
} finally {
// Release the lock
if (fd) {
fs.flockSync(fd, 'un');
fs.closeSync(fd);
}
}
What is the code about?In the above example, the fs.openSync() method is used to open the file and set an exclusive lock on it. This means that any other process trying to access the file will be blocked until the lock is released. The file is then read, modified, and written back to using the fs.readFileSync(), fs.writeFileSync() method. The fs.flockSync(fd, 'un') method is used to release the lock on the file.
It's important to note that this example uses synchronous methods, as they are simpler to understand and use. But in real-world scenarios, using asynchronous methods is more recommended.
Therefore, It's also important to make sure that the lock is released when you're done with the file. This is why the lock is released in the finally block of the try catch block. This way, the lock will be released even if an error occurs while working with the file.
