1. The correct statement about UDP Flood and TCP Flood attack prevention is: (Multiple Choice)

The UDP protocol is connectionless and therefore cannot be implemented by source probe.

Prevent UDP Flood by analyzing the rules and characteristics of a host sending UDP packets, this rule and feature is called fingerprint learning.

The fingerprint learning function of UDP packets learns all fields of the packet data segment.

UDP and TCP protocols can be implemented through proxy technology.

Question 3 of 20

4. What is the correct statement about MTU and PMTU? (Multiple Choice)

MTU (Maximum Transfer Unit) refers to the size of the largest data message that can be transmitted in the network, in bytes.

The device checks the MTU on the inbound interface. If the packet size exceeds the MTU value, it will be discarded.

In an IP network, the source address to the destination address may pass through interfaces with different MTU values, and the largest MTU value is the PMTU of the path.

Detecting PMTU is obtained by detecting the PMTU value of the specified destination IPv4 address, and then using the MTU value to send the message.

Question 4 of 20

5. In NGFW, to use the RBL blacklist, which of the following key options do network administrators need to configure? (Multiple Choice)

DNS server

Answer code

RBL server IP address

SMTP server IP address

Question 8 of 20

9. The internal network IP address of a Web server deployed in an enterprise DMZ is 10.1.1.3 and the port is 8080. The public network address is 1.1.1.2 and the external port number is 80.

Configure the following command on the firewall:

[USG6600] security-policy

[[USG6600-policy-security] rule name untrust_to_mz

[USG6600-policy-security-rule-untrust_to_mz] source-zone untrust

[USG6600-policy-security-rule-untrust_to_mz] destination-zone dmz

[USG6600-policy-security-rule-untrust_to_mz] destination-address 1.1.1.2 32

[USG6600-policy-security-rule-untrust_to_mz] service http

[USG6600-policy-security-rule-untrust_to_mz] action permit

[USG6600] nat server webserver protocol tcp global 1.1.1.2 www inside 10.1.1.3 8080

The external network PC cannot access the Web Server 10.1.1.3 inside the enterprise. Please analyze the reasons. The most likely reasons are:

The firewall does not open the default packet filtering policy from the untmut area to the dmz area.

Firewall untrust to DMZ zone security policy should be configured as service 8080

Firewall untrust to DMZ zone security policy should be configured as destination-address 10.1.1.3 32

The firewall should be configured as nat server webserver protocol tcp global 1.1.1.2 80 inside 10.1.1.3 8080

Question 9 of 20

10. In the terminal security management, the whitelist + blacklist mode is adopted. Which of the following is a formal behavior?

The software in the whitelist is not installed on the terminal host, and the software in the blacklist is not installed.

The terminal host installs all the software in the whitelist, and the software in the blacklist is not installed.

The terminal host installs some software in the whitelist, and the software in the blacklist is not installed.

The terminal host installs all the software of the whitelist terminal, and also installs some software in the blacklist.

Question 10 of 20

11. Hundreds of people in a medium-sized enterprise network access the Internet through the company's firewall, and the company deployed an enterprise portal in the firewall DMZ. As an IT security officer, which standard you should follow to procure and deploy Internet access audit products?

Question 11 of 20

12. The three servers have a centralized networking solution. As shown in the figure, the administrator finds that only one of the three Agile Controllers in the resource pool is alive.

In this case, which of the following descriptions is correct?

The three database servers are not working properly. Only one of the three Agile Controllers in the resource pool is alive. In this case, the Agile Controller services are all transferred to the surviving Agile Controller and function properly. Terminal authentication, access control, software distribution, patch installation, and asset management are not affected.

After the Agile Controller is started, each Agile Controller immediately reads the database and caches it on the local hard disk. If all the databases become unavailable due to the fault, the Agile Controller continues to maintain the operation of the Agile Controller service by using the cache that is saved at that time.

At this point, you can try to restart the surviving Agile Controller and repair the database server on reboot.

The escape channel on the firewall is now open.

Question 12 of 20

13. Border network security, which of the following options are there for planning deployment recommendations?

Security domain isolation

IPS real-time intrusion prevention

If the public network address of the NAT server is on the same network segment as the corresponding public network interface address, you do not need to configure blackhole routing.

If the public network address of the NAT server is not in the same network segment as the corresponding public network interface address, you do not need to configure blackhole routing.

If the public network address of the NAT server is the interface address, if the blackhole route of the address is configured, the service access to the firewall itself will be abnormal.

It is not possible to configure the NAT Server for users of the root firewall on the virtual firewall.

The protocol is an IP packet of AH and ES

The source port is UDP packets of 500 and 4500.

The destination port is UDP packets of 500 and 4500.

The destination port is a UDP packet of 1701.

Question 19 of 20

20. The firewall is deployed between the wireless user's mobile terminal and the WAP gateway. The mobile terminal is in the trust zone and the WAP gateway is in the untrust zone. The configuration is as follows:

[USG] ad 3000

[USG-acl-adv-3000] rule permit ip destination 202.10.10.2 0

[USG-acl-adv-3000] quit

[USG] fir-all zone trust

[USG-zone-trust] destination-nat 3000 address 200.10.10.2

[USG-zone-trust] quit

Which of following description is correct?

This configuration can also be applied to the server address mapping scenario.
