Kirsten manages the infrastructure that hosts her company's CRM platform. She currently has a production environment that all of the users access. However, she was recently reading about the concept of creating a second production environment where patches and updates are applied and then traffic is shifted over to the second environment once it has been tested. Which of the following describes the methodology that she is considering implementing?

a. Rolling deployment
b. Blue-green deployment
c. Duplicate deployment
d. Canary deployment

Answer:

The methodology that Kristen is considering to implement is:

d. Canary deployment.

Explanation:

This deployment type creates a second production environment (better called a testing environment).  Here, patches and updates are first applied for testing purposes before shifting traffic to the main production environment.  In a server environment, the idea of canary deployment is to first deploy the changes to a small subset of servers, test them before rolling out the changes to the rest of the servers. It enjoys some advantages over other deployment strategies because it allows for testing.

Suppose that TCP's current estimated values for the round trip time (estimatedRTT) and deviation in the RTT (DevRTT) are 350 msec and 10 msec, respectively (see Section 3.5.3 for a discussion of these variables). Suppose that the next three measured values of the RTT are 220 msec, 260 msec, and 390 msec respectively.
(Compute TCP's new value of DevRTT, estimatedRTT, and the TCP timeout value after each of these three measured RTT values is obtained. Use the values of α = 0.125, and β = 0.25. Round your answers to two decimal places after leading zeros.)
What is the estimatedRTT after the first RTT?

A major public university graduates approximately 10,000 students per year, and its development office has decided to build a Web-based system that solicits and tracks donations from the university's large alumni body. Ultimately, the development officers hope to use the information in the system to better understand the alumni giving patterns so that they can improve giving rates.

a. What kind of system is this?
b. What different kinds of data will this system use?
c. On the basis of your answers, what kind of data storage format(s) do you recommend for this system?

I have a Dell laptop and last night it said that it needed to repair it self and asked me to restart it. So I did but every time I turn it on it shuts itself down. I had a problem exactly like this before with my old computer, was not a Dell though, and I ended up having to have it recycled. This computer I have now is pretty new and I really don't want to have to buy a new computer. What should I do to fix this problem? Please help, I'm a college student almost ready to graduate and all of my classes are online. I'm starting to panic. Thanks for helping me figure this situation out.

cin >> mark;
count++;

if (mark >= 0 && mark <= 60);
count1 = count1 + 1;
else if (mark >= 61 && mark <= 70);

IN C++
A. Create an abstract base class called Currency with two integer attributes, both of which are non-public. The int attributes will represent whole part (or currency note value) and fractional part (or currency coin value) such that 100 fractional parts equals 1 whole part.
B. Create one derived class - Money - with two additional non-public string attributes which will contain the name of the currency note (Dollar) and currency coin (Cent) respectively. DO NOT add these attributes to the base Currency class.
C. In your base Currency class, add public class (C++ students are allowed to use friend methods as long as a corresponding class method is defined as well) methods for the following, where appropriate:
Default Construction (i.e. no parameters passed)
Construction based on parameters for all attributes - create logical objects only, i.e. no negative value objects allowed
Copy Constructor and/or Assignment, as applicable to your programming language of choice
Destructor, as applicable to your programming language of choice
Setters and Getters for all attributes
Adding two objects of the same currency
Subtracting one object from another object of the same currency - the result should be logical, i.e. negative results are not allowed
Comparing two objects of the same currency for equality/inequality
Comparing two objects of the same currency to identify which object is larger or smaller
Print method to print details of a currency object
All of the above should be instance methods and not static.
The add and subtract as specified should manipulate the object on which they are invoked. It is allowed to have overloaded methods that create ane return new objects.
D. In your derived Money class, add new methods or override inherited methods as necessary, taking care that code should not be duplicated or duplication minimized. Think modular and reusable code.
E. Remember -
Do not define methods that take any decimal values as input in either the base or derived classes.
Only the print method(s) in the classes should print anything to console.
Throw String (or equivalent) exceptions from within the classes to ensure that invalid objects cannot be created.
F. In your main:
Declare a primitive array of 5 Currency references (for C++ programmers, array of 5 Currency pointers).
Ask the user for 5 decimal numbers to be input - for each of the inputs you will create one Money object to be stored in the array.
Once the array is filled, perform the following five operations:
Print the contents of the array of objects created in long form, i.e. if the user entered "2.85" for the first value, it should be printed as "2 Dollar 85 Cent".
Add the first Money object to the second and print the resulting value in long form as above.
Subtract the first Money object from the third and print the resulting value in long form as above.
Compare the first Money object to the fourth and print whether both objects are equal or not using long form for object values.
Compare the first Money object to the fifth and print which object value is greater than the other object value in long form.
All operations in the main should be performed on Currency objects demonstrating polymorphism.
Remember to handle exceptions appropriately.
There is no sample output - you are allowed to provide user interactivity as you see fit.

If we were ever to use this pizza ordering program again, we would want to use mainline logic to control its execution. The way it is written, it will automatically execute as soon as it is imported.
Re-write this program, enclosing the top level code into the main function. Then execute the main function. Enter appropriate input so the output matches that under Desired Output.
# Define Function
def pizza(meat="cheese", veggies="onions"):
print("You would like a", meat, "pizza with", veggies)
# Get the User Input
my_meat = input("What meat would you like? ")
my_veggies = input("What veggie would you like? ")
# Call the Function
pizza(meat=my_meat, veggies=my_veggies)
desired output:
What meat would you like? cheese
What veggie would you like? onions
You would like a cheese pizza with onions
2) We want to generate 5 random numbers, but we need the random module to do so. Import the random module, so the code executes.
# Define main function
def main():
print("Your random numbers are:")
for i in range(5):
print(random.randint(1, 10))
# Call main function
main()
desired output:
Your random numbers are:
[x]
[x]
[x]
[x]
