Laura manages DLP for a large company where some employees have COPE and some have BYOD. What DLP issue could these devices present?
Answer:
For the COPE device, there won't be a lot of risks, because this type of model is very secure and trustworthy. The device belongs to the company and only the corporative use is allowed. The company owns maximum control on the information managed by the device. Some Blackberry devices were only COPE designed.
For the BYOD device, is the opposite, because this type of model is very unsecure since it doesn't count with the security barriers like the COPE model does, leading to the user losing critical information or getting hacked by installing malware. Even though it is a cheaper alternative for a lot of companies, it's far away from beign the most recommendable in terms of security, productivity and privacy.

You're responsible for technical support at a High School. You're concerned about students with some technical knowledge reconfiguring machines, either maliciously or not. You have already made sure Windows is secure and the students' login has the minimum necessary privileges. What else should you do to prevent students from re-configuring the school lab computers?
Answer:
setup a password for the BIOS
Explanation:
The BIOS refers to Basic Input/Output System. When a BIOS password is set, it will enforce autentication whenever an attempt is made to login at startup. Remember that the computer's microprocessor uses the BIOS to bootup, and it is also responsible for managing information flow between the OS and other devices, therefore very sensitive settings are maintained here, setting up a password will further ensure that that students do not intentionally recomfigure the computers in the school laboratory.
Which routing protocol does an exterior router use to collect data to build its routing tables?
A. OSPFB. IPC. RIPv2D. BGP
Answer:
D. BGP
Explanation:
In order to exchange routing information with another AS (Autonomous Systems) only, exterior routers use an exterior routing protocol, like BGP (Border Gateway Protocol) or EGP (Exterior Routing Protocol).
BGP is an application-layer protocol in the TCP/IP suite, that uses a well-known TCP port (179) in order to deliver information reliably.
It is important to note that in order to exchange routing data within his own AS, the router uses an interior routing protocol, like OSPF.

Write a static method named printTwoDigit that accepts an integer n as a parameter and that prints a series of n randomly generated numbers. The method should use Math.random() to select numbers in the range of 10 to 19 inclusive where each number is equally likely to be chosen. After displaying each number that was produced, the method should indicate whether the number 13 was ever selected ("we saw a 13!") or not ("no 13 was seen."). You may assume that the value of n passed is at least 0.
Answer: Following code is in java language :-
import java.lang.Math;
public class
{
public static void main(String args[])
{
printTwoDigit(6); //6 is the number of random numbers to be generated
}
public static void printTwoDigit(int n)
{
int i = 0;
int arr[]=new int[n]; //will declare a array of n size
int flag=0;
while(i<n)
{
arr[i] = 10 + (int)(Math.random()*10); //produce random number each time
System.out.println(arr[i]+" "); //print all random numbers
i++;
}
for(i=0;i<n;i++)
{
if(arr[i]==13) //to check if 13 was generated
{
flag=1;
break;
}
}
if(flag==1)
System.out.println("we saw a 13"); //this line is mentioned in question
else
System.out.println("no 13 was seen"); //this line is mentioned in question
}
}
OUTPUT :
15
11
15
19
13
19
we saw a 13
Explanation:
In the above code, an array is declared with size n(which is passed as an argument to the function) to store the list of all random number produced.Random() is multiplied by 10 so that it can produce a number 10 numbers starting from 0 and then 10 is added to the generated number so that minimum value generated would be 10.All numbers generated are printed to console n times and stored in arr.After that arr is checked for value 13 so it can print whether 13 was produced or not.Final answer:
The printTwoDigit method generates n random numbers between 10 and 19 using Math.random(), checks if the number 13 appears, and prints a corresponding message.
Explanation:
The method printTwoDigit generates and prints a series of random numbers between 10 and 19, using the Math.random() function. To generate numbers specifically in the range of 10 to 19, we can multiply the result of Math.random() by 10 and then add 10 to shift the range. After generating each number, the method checks if the number 13 was generated and prints a message accordingly. If at least one instance of the number 13 appears during the sequence, the message "we saw a 13!" is displayed; otherwise, the message "no 13 was seen." is shown.
Here is an example implementation of the method:
public static void printTwoDigit(int n) {
boolean saw13 = false;
for(int i = 0; i < n; i++) {
int randomNum = (int)(Math.random() * 10) + 10;
System.out.print(randomNum + " ");
if(randomNum == 13) {
saw13 = true;
}
}
System.out.println();
if(saw13) {
System.out.println("we saw a 13!");
} else {
System.out.println("no 13 was seen.");
}
}
In computer science, what are two names that are used to describe data structures organized by association
Answer:
Answer to the following question are,
Association list TablesExplanation:
Because these are the two associations data structures.
Association List: are referred to that data type which contains the pair of the key and item in the Java Programming Language and Python Programming Language, it is called a dictionary data type.Tables or Hash Tables: are referred to that data type which converts the keys into the integer value.Final answer:
In computer science, 'associative arrays' and 'maps' are two data structures organized by key-value associations, which enable efficient retrieval of data.
Explanation:
In computer science, two names that are often used to describe data structures organized by association are associative arrays and maps. An associative array (also known as a dictionary or a map) is a data structure that pairs unique keys with corresponding values.
This allows for efficient data retrieval based on those keys. Similarly, a map is a collection of key-value pairs where each key is unique and is used to store and retrieve data. Both associative arrays and maps are highly useful for situations where quick lookups of associated data are necessary.
