FALSE

18. Regarding the global configuration of file filtering configuration files for Huawei USG6000 products, which of the following descriptions is correct?

File filtering, content filtering, and anti-virus detection are not available when files are corrupted. At this time, files can be released or blocked according to business requirements.

When the file extension does not match, if the action is "Allow" or "Alert", file filtering, content filtering and anti-virus detection will be performed according to the file type.

When the number of compression layers of a file is greater than the configured "Maximum number of decompression layers", the firewall cannot filter the file.

When the file type cannot be identified, file filtering, content filtering and anti-virus detection are not performed.

19. IPS is an intelligent intrusion detection and defense product. It can not only detect the occurrence of intrusion, but also suspend the occurrence and development of intrusion behaviors in real time through a certain response method, and protect the information system from substantial attacks in real time.

Which of the following statements about IPS is false?

IPS is an intrusion detection system that can block intrusions in real time.

IPS makes IDS and firewall unified.

IPS must be deployed in bypass mode in the network.

The common IPS deployment mode is in-line deployment.

20. The figure below shows the configuration of the URL filtering configuration file. Which of the following statements about this configuration is correct?

The firewall will check blacklist entries before checking whitelist entries.

Assuming that the user visits the www.exzample.com website, which belongs to both the humanities and social networking categories, the user cannot access the website at this time.

The user visits the website www.exzample.com. When the black and white list is not hit, the user will query the predefined URL category entry.

The default action means that all sites are allowed access. Hence the configuration is wrong here.

The management center mainly completes the processing of attack events, controls the traffic diversion strategy and cleaning strategy of the cleaning center, and classifies and views various attack events and attack traffic, and generates reports.

The main function of the cleaning center is to detect and analyze the DDoS attack traffic on the mirrored or split traffic, and provide the analysis data to the management center for judgment.
