Denied topics are the appropriate Amazon Bedrock Guardrails feature because the company wants to identify and prevent responses relating to a specific subject area—in this case, unwanted political content.
AWS explains: “You can specify a set of denied topics in a guardrail that are undesirable” for a generative AI application. When a prompt or response is identified as belonging to a configured denied topic, the guardrail can block that content and return the configured blocked-response message.
The company could therefore define a denied topic describing political advocacy, political commentary, politically influenced recommendations, or whatever political-content boundary its newsletter policy prohibits. Amazon Bedrock Guardrails evaluates content contextually against the topic definition rather than relying solely on individual keywords.
This distinction is important because political ideas can be expressed without using predictable keywords. A contextual denied-topic policy is consequently better suited than maintaining a static list of political terms.
Word filters , option A, block configured words or phrases through direct matching. They are useful for profanity, competitor names, or other exact terms but are less suitable for broad conceptual topics.
Sensitive information filters , option C, detect personally identifiable information and configured sensitive patterns. They address privacy rather than political subject matter.
Content filters , option D, detect predefined harmful-content categories. Current Amazon Bedrock Guardrails categories include Hate, Insults, Sexual, Violence, Misconduct, and Prompt Attack. Politics is not one of those predefined content-filter categories.
Denied topics are specifically intended for application-specific subjects that the organization chooses to prohibit. AWS gives examples such as a banking assistant being configured to avoid investment-advice or cryptocurrency discussions.
Consequently, the RAG architecture does not change the appropriate control. Guardrails can evaluate generated output after retrieval and generation, and the company can define politics-related content as an undesirable subject.
Therefore, the correct answer is B. Denied topics .
