Answer:

The answer is D. Implement STP or RSTP.

Explanation:

STP (Spanning Tree Protocol) was built to serve as a remedy for network issues. Existing before switches were developed, it works as a substitute for a switch when a switch is wired incorrectly (as seen in the question) or when it fails. STP has two roles:

  1. To serve as an alternative when there is network failure or changes.
  2. To block out issues caused by loops on a network

RSTP (Rapid Spanning Tree Protocol) was built to optimize the standard STP. When there is a topology change, spanning tree convergence is much faster than the standard STP.

To prevent network failure in the future, STP or RSTP should be implemented.

Write a method for the Invitation class that accepts a parameter and uses it to update the address for the event.
DerKrebs [107]

Answer:

public class Invitation {

 private String hostname;

 private String address;

  public Invitation(String n, String a) {  // constructor that accepts two strings.

   hostname = n;

   address = a;

 }

  public String getHostname() {

   return hostname;

 }

 public void setAddress(String a) {

   address = a;

 }  

 public String invite(String guest) {

   return "Hello" +guest+ ", you are invited to my party at " +address+". "+hostname+".";

 }

 public Invitation(String host, String address) {

   this.address = address;

   this.hostname = host;

 }

}

Explanation:

The Java program defines a class called "Invitation". The class constructor has two string arguments or parameters for the host of the event and the address. The invite method is used to generate the string invite message with the name of the guest as the argument. Use the "setAddress" method to set a new location of the event and the "getHostname" to get the name of the event host.

Horizontal and vertical flips are often used to create ___.
mixer [17]

Answer:

Rotation of an image

Explanation:

The correct answer is -  Rotation of an image

Reason -

When you rotate an object, it moves left or right around an axis and keeps the same face toward you.

When you flip an object, the object turns over, either vertically or horizontally, so that the object is now a mirror image.
