Management wants to ensure any sensitive data on company-provided cell phones is isolated in a single location that can be remotely wiped if the phone is lost. Which of the following technologies BEST meets this need?a. Geofencingb. containerizationc. device encryptiond. Sandboxing
Answer:
B. Containerization.
Explanation:
In this scenario, management wants to ensure any sensitive data on company-provided cell phones is isolated in a single location that can be remotely wiped if the phone is lost. The technology which best meets this need is containerization.
In Computer science, containerization can be defined as a process through which software applications are used or operated in an isolated space (environment). It uses an operating system level virtualization method, such as a single host OS kernel, UFS, namespaces, Cgroups, to run software applications.
Hence, using the containerization technology makes it easy to wipe off the cell phones if lost because it is isolated in a single location.
In the design phase of the systems development life cycle (SDLC), the _____ design is an overview of the system and does not include hardware or software choices. Group of answer choices
Answer:
"Conceptual" is the correct answer.
Explanation:
SDLC would be a particular implementation of a software administration that defines the processes responsible for the creation of such an organization or project, through preliminary feasibility studies to accomplished program activities.The conceptual design seems to be the very first phase of the cycle of brand management, using designs as well as other diagrams or models. It offers an implementation of the study product as a result of a collection of interconnected values and principles about what it will do, function, and look in a user-friendly way."The principle of ______________ states that programs tend to access data and instructions nearby recently used data and instructions."
Answer:
Locality of reference.
Explanation:
In computing, The principle of locality of reference is the probability of a processor to repeatedly access the same set of memory locations within a small time interval. This reference of locality can be spatially based (repetitive usage of data within the same location on the computer memory), or temporally based (repetitive usage of a particular data or resources within a shot time interval). The ability of some computing system to perform this action increases their predictability, and efficiency of memory hierarchy use, among other abilities.

If an organization’s DNS server can resolve a DNS request from its own cache, the DNS server is said to be ____.
Answer:
Answered below
Explanation:
The DNS server is said to be a caching-only DNS server.
A caching-only Domain Name System server, works by recieving queries from the client, proceeds to perform queries against other named servers, then caches the results and returns the results to the client.
Subsequent queries are resolved and returned for the specified host straight from the the cache, by the server, instead of submitting to the external server.
The advantage of this process is that it reduces traffic from outgoing DNS and speeds up the name resolution. Also, there is a reduction in the amount of query traffic.

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.

1. Cases Prudence has a special (cubic) die. The values on its face are the integers from 1 to 6, but they are not arranged ae in a normal die. When Prudence first tosses the die, the sum of the values on the four side faces is 15. In her second toss, the sum of these values is 12. Find what value appears in the face opposite 6 on Prudence’s special die. (Hint: what are possible values for the top and bottom face when the sum of the side faces is 12).
Answer:
The definition of the subject in question is presented in section elsewhere here.
Explanation:
The total value of almost all of the quantities mostly on unique die features will indeed be:
⇒ [tex]1+2+3+4+5+6[/tex]
⇒ [tex]21[/tex]
The number of the 4 lateral sides throughout the first tossing will be 15, therefore determines the total of both top and bottom features would be:
⇒ [tex]21-15[/tex]
⇒ [tex]6[/tex]
The compositions including its {top and bottom} current valuations that give a total of Six include {1, 5}, {5, 1}, {2, 4}, as well as {4, 2}. Consequently, because neither of those variations includes Six, it indicates that six doesn't really feature on the very first toss mostly on high or low hand.
And then let's look at second tossed situation. Throughout this particular instance, the total amount obtained would be 12.
Which means it has to be the number of top and bottom:
⇒ [tex]21-12[/tex]
⇒ [tex]9[/tex]
{4, 5},{5, 4}, {6, 3}, and {3, 6} seem to be the {top, bottom} facial variations that provide a total of Nine.
Currently regarding all the tosses, {6, 3} and perhaps {3, 6} have been the only situations wherein the 6 emerge towards top or bottom. Then the value of the unique die mostly on face identical to 6 must've been 3.

Do each of the following in the main function:
a) Write the function prototype for function zero, which takes a double array big_nums and does not return a value.
b) Write the function call for the function in part a.
c) Write the function prototype for function add1AndSum, which takes an integer array one_small and returns an integer.
d) Write the function call for the function described in part c.
Answer:
a)
void zero(double big_nums[]);
b)
zero(big_nums)
c)
int add1AndSum (int one_small[]);
d)
add1AndSum(one_small);
Explanation:
a)
void zero(double big_nums[]);
in this statement:
zero is the name of the function
void is used as the function does not return a value.
The function zero takes an array parameter i.e. big_nums[]
big_nums is the name of the array
big_nums[] array has a data type double
b)
zero is the name of the function
In part a) function zero has a parameter which is the array big_nums. So in order to call this function an array has to be passed as a parameter to this function.
So in this statmenent zero(big_nums) the array big_nums is passed to the zero function. You can also declare a new double type array with a different name in main() function and can pass this to the zero function as:
double array[ ] = { 20.6, 30.8, 5.1};
zero(array);
Look at the following program for the better understanding of part a) and b)
#include <iostream> //for using input output functions
using namespace std; //to access objects like cin cout
void zero (double big_nums[]); // function prototype
int main() { //start of main() function
double a[ ] = { 20.6, 30.8, 5.1}; // double type array a with elements
zero(a); } //calls zero function passing array a to the function
void zero(double big_nums[]){ // function zero with double type array big_nums as parameter and the function returns no value
int i;
for(i=0;i<3;++i) {
cout<<big_nums[i]; } } //prints the elements of array
c)
add1AndSum is the name of the function
int is used as the function does not return an integer.
The function add1AndSum takes an integer array parameter i.e. one_small[]
one_small is the name of the array
one_small[] array has a data type int
d)
add1AndSum is the name of the function
In part c) function add1AndSum has a parameter which is the array one_small. So in order to call this function an array has to be passed as a parameter to this function.
So in this statement add1AndSum(one_small); the array one_small is passed to the add1AndSum function. You can also declare a new int type array with a different name in main() function and can pass this to the add1AndSum function.
Develop a CPP program to test is an array conforms heap ordered binary tree. This program read data from cin (console) and gives an error if the last item entered violates the heap condition. Use will enter at most 7 numbers. Example runs and comments (after // ) are below. Your program does not print any comments. An output similar to Exp-3 and Exp-4 is expected.
Exp-1:
Enter a number: 65
Enter a number: 56 // this is first item (root,[1]) in the heap three. it does not violate any other item. So, no // this is third [3] number, should be less than or equal to its root ([1])
Enter a number: 45 // this is fourth number, should be less than or equal to its root ([2])
Enter a number: 61 // this is fifth number, should be less than or equal to its root ([2]). It is not, 61 > 55. The 61 violated the heap.
Exp-2:
Enter a number: 100
Enter a number: 95 1/ 95 < 100, OK
Enter a number: 76 // 76 < 100, OK
Enter a number: 58 // 58 < 95, OK
Enter a number: 66 1/ 66 < 95, OK
Enter a number: 58 // 58 < 76, OK
Enter a number: 66 // 66 < 76, OK
Exp-3:
Enter a number: -15
Enter a number: -5
-5 violated the heap.
Exp-4:
Enter a number: 45
Enter a number: 0
Enter a number: 55
55 violated the heap.
Answer:
Following are the code to this question:
#include<iostream>//import header file
using namespace std;
int main()//defining main method
{
int ar[7];//defining 1_D array that stores value
int i,x=0,l1=1,j; //defining integer variable
for(i=0;i<7;i++)//defining for loop for input value from user ends
{
cout<<"Enter a Number: ";//print message
cin>>ar[i];//input value in array
if(l1<=2 && i>0)//using if block that checks the array values
{
x++;//increment the value of x by 1
}
if(l1>2 && i>0)//using if block that checks the array values
{
l1=l1-2;//using l1 variable that decrases the l1 value by 2
}
j=i-x;//using j variable that holds the index of the root of the subtree
if(i>0 && ar[j]>ar[i])// use if block that checks heap condition
{
l1++; //increment the value of l1 variable
}
if(i>0 && ar[j]<ar[i])// using the if block that violate the heap rule
{
cout<<ar[i]<<" "<<"Violate the heap";//print message with value
break;//using break keyword
}
}
return 0;
}
Output:
1)
Enter a Number: -15
Enter a Number: -5
-5 Violate the heap
2)
Enter a Number: 45
Enter a Number: 0
Enter a Number: 55
55 Violate the heap
Explanation:
In the above-given C++ language code, an array "ar" and other integer variables " i,x,l1, j" is declared, in which "i" variable used in the loop for input values from the user end.In this loop two, if block is defined, that checks the array values and in the first, if the block it will increment the value of x, and in the second if the block, it will decrease the l1 value by 2.In the next step, j variable is used that is the index of the root of the subtree. In the next step, another if block is used, that checks heap condition, that increment the value of l1 variable. In the, if block it violate the heap rule and print its values.Algorithm

what level of security access should a computer user have to do their job?
Answer:
A computer user should only have as much access as required to do their job.
Explanation:
A computer user should not be able to access resources outside of their job requirement, as this poses a potential attack vector for an insider threat. By limiting the scope of resources to just what is needed for the user's specific job, the threat to the system or company can be mitigated with additional access control features for the computer user. Never allow permission higher than what are needed to accomplish the task.

Which of the factors below is NOT a cause of online disinhibition?
O Anonymity
O Lack of nonverbal cues
Lack of tone of voice
Smartphones
Answer:
Lack of tone of voice
Explanation:
Remember, online disinhibition refers to the tendency of people to feel open in communication via the internet than on face to face conversations.
A lack of tone voice isn't categorized as a direct cause of online disinhibition because an individual can actually express himself using his tone of voice online. However, online disinhibition is caused by people's desire to be anonymous; their use of smartphones, and a lack of nonverbal cues.
