Answer:
Car car = new Car();
Explanation:
Here we declare a variable called car which is a reference to an object of type Car.
Next we create a new object of type Car by using the new keyword. Here we are invoking no argument constructor of class Car. In case the car class has other constructors which take additional arguments, we could have initialized our object using the corresponding version of new.
The reference variable car is initialized then to the newly created object of type Car as described in the previous step. Now we can use the car reference variable to invoke relevant methods defined in the Car class.
External hard drives typically connect to a computer via an external port (such as a USB or <u>thunderbolt</u> port) or a wireless connection.
<h3>What is a hard drive?</h3>
A hard drive can be defined as an electro-mechanical, non-volatile data storage device that is made up of magnetic disks (platters) that rotates at high speed.
In Computer technology, all hard drives are commonly installed on computers and other digital service for the storage of digital files and to enable the booting of a computer through its operating system (OS).
<h3>What is a memory?</h3>
A memory can be defined as a terminology that is used to describe the available space on an electronic device that is typically used for the storage of data or any computer related information such as:
In conclusion, all external hard drives typically connect to a computer through an external port such as a USB, <u>thunderbolt</u> port, or a wireless connection.

Answer:
(B) It allows an attacker to redirect targets to malicious webserver.
(D) It affects any clients querying the poisoned DNS server.
Explanation:
DNS cache poisoning is a serious type of attack that is designed to exploit the vulnerabilities inherent in a Domain Name Server (DNS) where a user is redirected from a real server to a fake one. It is also called DNS spoofing.
Normally, when your browser tries to visits a website through a given domain name, it goes through the DNS server. A DNS server maintains a list of domain names and their equivalent Internet Protocol addresses. This server (DNS) then responds to the request with one or more IP addresses for the browser to reach the website through the domain name.
The computer browser then get to the intended website through the IP address.
Now, if the DNS cache is poisoned, then it has a wrong entry for IP addresses. This might be via hacking or a physical access to the DNS server to modify the stored information on it. Therefore, rather than responding with the real IP address, the DNS replies with a wrong IP address which then redirects the user to an unreal website.
Although they might not be able to control your computer remotely as long as you are not trying to visit a web page via the poisoned information, there are other dangers attached to this type of attack.
Once the DNS server has been poisoned, any client trying to query the server will also be affected since there is no direct way of knowing if the information received from the server is actually correct.
Explanation:
A hub is used to send the message from one port to other ports.It does not know the specific address of the destination where the message needs to send.it works on Physical layer of the OSI model(layer 1).
A switch can handle data and it knows the specific address of the destination.A switch works on the data link Layer of the OSI model(layer 2).
