Among the ports provided by the firewall is used to connect to the server

Answer] The access modes provided by the :d firewall include transparent access and dissipation, NAT mode, route mode (gateway mode), and hybrid Changyan mode.

Hello, a firewall does not refer to a mail server that handles incoming and outgoing hosts. The firewall branch chain refers to the hardware and software that prevent infringements from entering and leaving the host. The following is also queried for you:

1.A high wall that prevents the spread of fire. 2.

A security measure on the Internet that protects data, prevents intrusion, restricts unauthorized access, and even ensures that no user can do anything disruptive to the Internet. It is a literal translation of the English firewall. 3.

A kind of network security equipment is equipped with luggage.

Select A for this question, firewalls are generally designed and integrated into the system functions of the computer operating system in order to prevent errors.

A term used in architectural design to refer to non-combustible walls that prevent fire from spreading to adjacent areas and have a fire resistance limit of not less than 3 hours. It is an important separation component used to divide fire partitions or prevent the spread of fire between buildings, which can effectively limit the fire in a certain space in the early stage of fire and in the process of fire extinguishing, and block the fire from spreading from one side of the firewall to the other, which plays an important role in reducing fire losses.

The following is about the characteristics of firewalls, and the wrong one is ().

a.Firewalls can filter network packets.

b.Firewalls can effectively record the activity on the network.

c.Firewalls can inspect the amount of traffic coming in and out of the internal network.

d.Firewalls can be used to block attacks from the network of the Inner Celebrants.

Correct Answer: Reputation Leak D

Answer]: B option A, the firewall is a non-combustible solid wall that prevents the fire from spreading to adjacent buildings or adjacent water cress flat fireproof partitions and the fire resistance limit is not less than 3 o. Option C, the firewall can effectively confine the fire to a certain space in the early stage of the fire and during the fire extinguishing process, and prevent it from spreading to one side of the firewall without spreading to the other.

Option d, if the firewall is set near the corner, the horizontal distance between the doors, windows, and openings on the wall on both sides of the inner corner is not less than 4 0m, and the distance can be unlimited when measures to prevent the horizontal spread of the fire such as setting up Class B fireproof windows are taken.

Answer]: B This question examines the main chemical fire and explosion prevention technology. There should be no ventilation and exhaust ducts in the firewall.

Answer]: The firewall technology is built on the internal and external network boundary can filter and block the mechanism, which can prevent unauthorized access to the internal network by the external network, can prevent the external network from attacking the internal network, and can also prevent the internal network from unauthorized access to the external network. However, firewalls alone cannot effectively prevent internal network attacks, and they usually do not have the ability to reverse trace network attacks.
