Answer:

Internet Control Message Protocol (ICMP) Echo Requests

Explanation:

A system that has Windows Firewall or antivirus or other third party antivirus enabled with their configuration setting set to default, ping command from another device will not be able to see if the device with an enabled firewall is alive.

The ping command sends Internet Control Message Protocol (ICMP) Echo Request to a destination device after the destination device will reply with a Reply packet. However, by default, firewalls, such as Windows firewall blocks ICMP Echo Requests from the external network and pinging will  work when the firewall is disabled or an exception is created that lets ICMP Echo Requests pass through the firewall.

Firlakuza [10]

Answer:

Option (D) is the right answer.

Explanation:

DHCP term used as a short form of dynamic host configuration protocol, which is used to assigns the IP address automatically according to the network.

According to the scenario, the system is getting the wrong IP address that resulting in internet disconnection which is a failure of the DHCP server because it is responsible for assigning the right IP address to the system.

Hence option (D) is the most appropriate answer.

While other options are wrong because of the following reasons:

  • Static IP is the type of IP address which is fix and doesn't change in the system after rebooting, hence it has no connection in the change of IP address.
  • If the DHCP server is working well there is no chance of interference from the surrounding device.
  • Network setting has no connection with computer power supply as SMPS is used to give power and boot system only.

Aleksandr [31]

Answer:

import java.util.Scanner;

public class StudentScores

{

public static void main(String[] args) {

 Scanner scnr = new Scanner(System.in);

 final int NUM_POINTS = 4;

 int[] dataPoints = new int[NUM_POINTS];

 int controlValue;

 int i;

 controlValue = scnr.nextInt();

 for (i = 0; i < dataPoints.length; ++i) {

     dataPoints[i] = scnr.nextInt();

 }

 for (i = 0; i < dataPoints.length; ++i) {

     System.out.print(dataPoints[i] + " ");

 }

 System.out.println();

 for (i = 0; i < dataPoints.length; ++i) {

     if(dataPoints[i] < controlValue){

         dataPoints[i] = dataPoints[i] * 2;          

     }

     System.out.print(dataPoints[i] + " ");

 }

}

}

Explanation:

*Added parts highligted.

After getting the control value and values for the array, you printed them.

Create a for loop that iterates through the dataPoints. Inside the loop, check if a value in dataPoints is smaller than the contorolValue. If it is, multiply that value with 2 and assign it to the dataPoints array. Print the elements of the dataPoints
