Question restatement: _________ would not usually be placed in the DMZ.

Option 1: External DNS servers. In many security architectures, external DNS servers that respond to queries from the internet are placed in the DMZ or at least exposed to the untrusted network to provide name resolution to external clients. This makes this option plausible as something that could be in the DMZ, so the statement that this would not usually be placed in the DMZ is not strongly correct on its own. The reasoning against this option is that it can be placed in a DMZ to provide public DNS services while isolating the internal network.

Option 2: Public webservers. Public web servers are a classic DMZ service; they are exposed to the internet and kept separate from the internal network to reduce risk. Saying they would not usually be placed in the DMZ contradicts common practice, so this option is not the correct choice for the statement in question.

Option 3: Database servers. Database servers typically contain sensitive data and are usually kept on an internal network, protected behind firewalls and not exposed directly to the internet or the DMZ. This aligns with the idea that they would not usually be placed in the DMZ, making this the correct choice for the statement. The key concept is protecting valuable data by limiting direct access from the untrusted network.

Option 4: FTP servers. FTP services are often placed in the DMZ because they need to be accessible from the internet, allowing file transfers while isolating the internal network. Though not universal, placement in the DMZ is common, so claiming they would not usually be in the DMZ would not reflect typical configurations.

Summary of reasoning: External DNS servers and public web servers are commonly located in or exposed through the DMZ to serve external clients, so claiming they would not usually be placed there is inaccurate. FTP servers are also commonly in the DMZ for internet access. Database servers, due to their sensitive data and need for strong internal protection, are the best fit for the statement that they would not usually be placed in the DMZ.
