Answer:
A. They can use information about previous packets to make decisions about future packets.
E. They are more susceptible to DoS attacks than stateless firewalls
Explanation:
Assuming the following options:
A. They can use information about previous packets to make decisions about future packets.
B. They are most effective when placed in front of the router connected to the Internet
C. They can track the number of active TCP connections
D. They can fitter HTTP and HTTPS traffic in the inbound direction only
E. They are more susceptible to DoS attacks than stateless firewalls
A firewall by definition is a "software used to maintain the security of a private network. Firewalls block unauthorized access to or from private networks and are often employed to prevent unauthorized Web users or illicit software from gaining access to private networks connected to the Internet".
The basic purpose of a firewall is to control the traffic that is allowed to traverse from the internet.
Option A is correct since they use previous info in prder to make decisions about a site.
Option B is not true since the firewall is a software that not depends of the router connection to the internet, since the web is open for any IP.
Option C is not correct isnce the purpose for the firewalls is not analyze the acitve connections.
Option D is not correct since they can work in both directions and no present limitations in order to filter web pages to classify the info.
Option E is correct since one characteristic of the stateless firewalls compared to the stateful firewalls. Since "Stateless firewalls watch network traffic and restrict or block packets based on source and destination addresses or other static values" and present more security comaprd to the stateless stateful.
Final answer:
The correct options are A. They can use information about previous packets to make decisions about future packets and C. They can track the number of active TCP connections. Firewalls in an enterprise network can use information about previous packets and track the number of active TCP connections to enhance network security.
Explanation:
Two functions of firewalls in an enterprise network:
They can use information about previous packets to make decisions about future packets: Firewalls can track the state of connections and use this information to determine whether incoming packets are part of an established connection or if they are trying to initiate a new, potentially unauthorized connection.
They can track the number of active TCP connections: Firewalls can monitor the number of active Transmission Control Protocol (TCP) connections to ensure network resources are not overwhelmed by excessive connections or potential cyber threats.

With 2020 Kicks’ Easy-Fill Tire Alert, what happens when the correct pressure is reached during inflation?
Answer:
THE HORN SOUNDS when the correct pressure is reached during inflation with 2020 kicks' Easy-Fill Tire Alert
Explanation:
Properly inflated tires are able to save up to 11 cents per gallon on gas and extend a tire’s life by over 4,000 miles, but it’s hard to know when the tires are at the proper pressure. Luckily, Nissan’s Easy-Fill Tire Alert system will take away the guesswork and help fill tires to the correct pressure every time—without needing a handheld pressure device!
First, park your vehicle and apply the parking brake.
Leave the ignition on (accessory mode) but keep the engine off
As you start to fill a tire, the exterior lights will flash to indicate that the system is monitoring the change in pressure
Once the tire meets the correct pressure, the horn will go off to tell you it’s done
If the tire is over-inflated, the horn will sound again, and the hazard lights will flash 3 times to tell you that you need to release some air

A. When executing System.out.println(a1), the toString() method in the Object class is invoked.
B. When executing System.out.println(a2), the toString() method in the Object class is invoked
C. When executing System.out.println(a1), the toString() method in the A class is invoked.
D. The program cannot be compiled, because System.out.println(a1) is wrong and it should be replaced by System.out.println(a1.toString())
E. Both B and C.
This question is incomplete, it lacks a piece of code to analyze.
I think you wanted an answer to the following question:
Analyze the following code:
public class Test {
public static void main(String[] args) {
Object a1 = new A();
Object a2 = new Object();
System.out.println(a1);
System.out.println(a2);
}
}
class A {
int x;
@Override
public String toString() {
return "A's x is " + x;
}
}
A. When executing System.out.println(a1), the toString() method in the Object class is invoked.
B. When executing System.out.println(a2), the toString() method in the Object class is invoked
C. When executing System.out.println(a1), the toString() method in the A class is invoked.
D. The program cannot be compiled, because System.out.println(a1) is wrong and it should be replaced by System.out.println(a1.toString())
E. Both B and C.
Answer:
E. Both B and C.
Explanation:
toString() method is used to get the representation of this object as a string. When trying to display a string representation of an object usually the full name of the class will be displayed.
In the example above, line
System.out.println(a2);
would display something like
java.lang.Object@5ccd43c2
Obtained value can hardly serve as a good string description of an object. Therefore, toString() method is often overridden using @Override annotation (more info about @Override at https://beginnersbook.com/2014/07/override-annotation-in-java/)
Line
System.out.println(a1);
would display "A's x is 0" because it uses toString() method overridden in class A.
Which of the following statements correctly instantiate the Rectangle object myRectangle? (i) myRectangle Rectangle = new Rectangle(10, 12); (ii) class Rectangle myRectangle = new Rectangle(10, 12); (iii) Rectangle myRectangle = new Rectangle(10, 12);
Answer:
The answer is "option iii" .
Explanation:
In the given question it is defined that a class "Rectangle" is defined in the class a parameter constructor is created that accepts two parameters. In this question, we create an instance of the class. In object creation first, we define class name then object name and use new keyword in the Instance of class and pass parameters.
In option i), An object name is used first and then class name. It is not correct. In option ii), In instance creation of the class, we do not use class keyword that's why it is wrong.

Data ____ travel over the Internet from router to router until reaching their destinations.
Answer:
Packets.
Explanation:
A data packet is a unit of data carried by a packet-switched network. Data Packets are transmitted along a given network path. Data travels across internet in packets. A packet can carry 1,500 bytes maximum. A packet contains a header and a footer which tells computers what type of data is in the packet, whats the source and destination of the data.
Transmission control protocol and internet protocol is a collection of communication protocols that for sending and receiving date using internet. TCP breaks the data into packets and maintains the network connection and IP deals with the sending and receiving packets from one computer to other using a process called IP Routing which determines the path for the packets to follow from one computer to the other. Once the packets reach their destination, TCP reforms them into their original state.

A device in a subnet needs to send a packet to a device in a different subnet. To which device will it address the outgoing packet?
Answer:
The Router
Explanation:
A router is a layer 3 device in the OSI network model. As the name implies, it routes packets logically from source to destination. An interface in a router represents a segment or a configured stand-alone network, with a specific subnet mask.
Routers have routing tables that learns a network route statically or dynamically with protocols. When a packet is to be sent to a device in another network, the router receives the packet and forwards the traffic to the destination (through another interface, if connected directly) or to the next hop router interface alone the path to the destination.
When a networking device in a subnet needs to send a packet to another device in a different subnet, it will: address the outgoing packet to it's configured default gateway.
A router can be defined as a networking device that is designed typically for forwarding outgoing data packets between two or more networks based on a well-defined routing protocol.
Generally, routers are typically configured using a standard routing protocol with an IP address as the default gateway.
A subnet is an abbreviation for subnetwork and it can be defined as a logical subdivision (partitioning) of a larger IP network into two or more smaller IP networks.
In Computer Networking, when a networking device belonging to a particular subnet needs to send a packet to another networking device configured in a different subnet, it will address the outgoing packet to it's configured default gateway, which is mainly referred to as a router.
In conclusion, a router is the default gateway to which a networking device addresses or forwards an outgoing packet.
