I think answer is A and D but not B. For B, explanation is Application-layer proxy must be developed for each protocol. The development period is long, and the upgrade is difficult.

Hi, friend！

I didn't find out more about proxy firewalls. Google has a description of this product and the answer should include a D. But I think B should be there too, and look forward to more answers that can be studied together.
Application-based proxy firewall has the advantages of high security, can detect and scan the application layer, and is very effective in dealing with intrusions and viruses based on the application layer. Its disadvantage is that the overall performance of the system is greatly affected. Moreover, the proxy server must be set one by one for all the application types that the client may produce, which greatly increases the complexity of system management.
