Answer: Computer operator
Explanation:
Following the information given, we can deduce that Connie is employed as a computer operator. A computer operator is a role in IT whereby the person involved oversees how the computer systems are run and also ensures that the computers and the machines are running properly.
Since Connie keeps the operating systems up-to-date, ensures that memory and disk storage are available, and oversees the physical environment of the computer, then she performs the role of a computer operator.
In the right situations, the use of multi-threads can allow for application speedup. Provide a small code example that illustrates how threads can be used to arrive at an appropriate result. Identify if there is a point where too many threads might impact performance of the application. g
Answer:
Explanation:
Threads allow an applications to run faster because they allow various tasks to run at the same time instead of doing one at a time and having to wait for one to finish before starting the next task. However, if too many threads are running at the same time, or a thread has a very large task or requires another task to finish before finishing its own then this can drastically impact performance. Mainly because too many resources are being used at a single moment. The following code is a small example of how threads work in Python.
import threading
import time
def thread_function(name):
print("Thread {name}: starting")
time.sleep(2)
print("Thread {name}: finishing")
thread1 = threading.Thread(target=thread_function, args=(1,))
thread1.start()
time.sleep(1)
thread2 = threading.Thread(target=thread_function, args=(2,))
thread2.start()
thread2.join()

Given the following array definition, write a constant declaration named ArraySize that automatically calculates the size in bytes, of the array:
newArray DWORD 10,20,30,40,50
a) arraysize=(S-newArray)
b) arraysize#(S-new,Array)/2
c) arraySize- (S-newArray)/4
d) arraySize- (S-arraySize)
Answer:
ArraySize = ($ - newArray)
Explanation:
Given
Array name: newArray
Type: DWORD
Required
The size of the array in bytes
The following formula is used to calculate the size of an array in assembly language.
Variable = ($-Array name)
So, we have:
ArraySize = ($ - newArray)
Where ArraySize is the variable that holds the size of newArray (in bytes)
I have a variable and set it equal to 5. 1 then send it as an argument to a function that adds 5 to the variable passed in. Outside the function print the variable (after the function executes).
What will it print?
A. 5+1
B. 4
C. 6
D. 5
Answer:
D. 5
Explanation:
If the variables original value was 5 then the value that will be printed is 5. This is because the variable is being passed as a parameter into the function and 5 is being added to the parameter value, not the actual global variable outside. Therefore, in order for the adjusted value to be printed then that new value that is returned by the function needs to be saved in a new variable. This can be seen in the example code below.
You have two microservices that need to communicate with each other without holding up a thread on either end. One service will receive an ID and return a message once the job is complete.
Which communication framework should be used?
A.) Have a shared database that allows both
applications to read and write to the tables to share the data instead of having to communicate
B.) Use asynchronous messaging to send and receive messages between each microservice
C.) Abandon the microservice architecture so no interaction is needed
D.) Create a third service to handle the interaction between the services
E.) Use a RESTful architecture for both, send the ID through a POST, and ping the service with a GET until a response is available
Answer: E. Use a RESTful architecture for both, send the ID through a POST, and ping the service with a GET until a response is available.
Explanation:
Since there are two microservices that need to communicate with each other without holding up a thread on either end, the communication framework should be used is a RESTful architecture for both, send the ID through a POST, and ping the service with a GET until a response is available.
REST is a software architectural style which is used in defining the set of rules that be used for the creation of web services. The REST architecture allows requesting systems to be able to access and manipulate web resources.

An engineer is configuring AMP for endpoints and wants to block certain files from executing. Which outbreak control method is used to accomplish this task
Question Completion with Options:
A. device flow correlation
B. simple detections
C. application blocking list
D. advanced custom detections
Answer:
The outbreak control method that is used to accomplish the task of configuring AMP for endpoints and to block certain files from executing is:
C. application blocking list
Explanation:
The application blocking list creates a list of application files, which the AMP continuously tracks and analyzes to compare the file activities with previous cyber attacks. Specifically, the AMP for Endpoints is a cloud-managed endpoint security solution, which provides a retrospective alert to prevent cyber-security threats, and rapidly detects, contains, and remediates malicious files on the endpoints.
continuously tracks and analyzes files and file activities across your systems, and compares these events to what preceded or happened in past attacks. If a file exhibits malicious behavior, the AMP provides you with a retrospective alert which enables you to stop a potential threat from succeeding.

7. System software is the set of software programs that helps run the computer and coordinates instructions between application software and hardware devices. It consists of the operating system (OS) and utility programs. How does the mindset of the designer affect the design of the operating system (e.g., Windows vs. Linux)
Answer:
Explanation:
The main goal when designing an operating system (OS) is to make sure that the system is as efficient and intuitive as possible. This is the mindset that designers have when creating the operating system. However, this also creates drastically different designs between designers, mainly because one design structure will feel much more natural and intuitive to one designer but not another. Since the designer's own personal taste/mindset drastically affects the design, most companies find their target audience and survey/test various designs. This is done in order to find what features and styles best fit the vast majority of the people.

If every company is now a technology company, then what does this mean for every student attending a business college
Answer:
Explanation:
There are all sorts of possibilities for, say, inserting new technologies into existing processes. But most of these improvements are incremental. They are worth doing; in fact, they may be necessary for survival. No self-respecting airline, for instance, could do without an application that lets you download your boarding pass to your mobile telephone. It saves paper, can't get lost and customers want it.
But while it's essential to offer applications like the electronic boarding pass, those will not distinguish a company. Electronic boarding passes have already been replicated by nearly every airline. In fact, we've already forgotten who was first.
