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

Answers

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.

The statement that is false is: The boot process is the process for powering off a computer, which is the second option. The boot process is actually the process of starting or powering on a computer, not powering it off.

The boot process refers to the sequence of events that occur when a computer is powered on or restarted. It is the process of starting up the computer's hardware and loading the operating system into memory so that it is ready for use. During the boot process, the computer's firmware (such as the BIOS or UEFI) performs a series of checks and tests to ensure that the hardware components are functioning correctly. It then searches for the operating system on connected storage devices, such as the hard drive or solid-state drive, and loads it into memory.

If every company is now a technology company, then what does this mean for every student attending a business college

Answers

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.

Consider an Erlang loss system. The average processing time is 3 minutes. The average inter-arrival time is 3 minutes. The number of servers is 3. What is r (sometimes referred to as the offered load)

Answers

Answer:

r = 1

Explanation:

Average processing time ( p ) = 3 minutes

Average inter-arrival time ( a ) = 3 minutes

number of servers ( m ) = 3

Determine the value of r

r ( offered load ) = p/a

                          = 3 / 3  = 1

∴ value of r ( offered load ) = 1

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)

Answers

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.

Explanation:

From the group of answer choices provided the only one that may be a problem would be using the word name as a parameter. Although name is not a reserved word per say in JS it is in HTML, and since JS targets HTML it could cause some errors. This however does not prevent this code from running correctly. JS does not require semicolons anymore, and the opening and closing braces for a body of code does not need to be on their own lines. Also, variable names are not Strings and do not need to be inside quotes, even for console.log()

Write a program that accepts the lengths of three sides of a triangle as an input from the user: A, B, C

Validate the user input so that the user can only enter positive values for sides A, B, C. All three must be true:

A > 0
B > 0
C > 0

Answers

Answer:

The program in Python is as follows:

A = int(input("A: "))

B = int(input("B: "))

C = int(input("C: "))

while A<=0 or B <= 0 or C <= 0:

   A = int(input("A: "))

   B = int(input("B: "))

   C = int(input("C: "))

print("Valid inputs")

Explanation:

Get input for A, B and C

A = int(input("A: "))

B = int(input("B: "))

C = int(input("C: "))

The loop is repeated until inputs for A, B and C are above 0

while A<=0 or B <= 0 or C <= 0:

Get input for A, B and C

   A = int(input("A: "))

   B = int(input("B: "))

   C = int(input("C: "))

Print valid inputs when user inputs are correct

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

Answers

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.
