Implement Memory Systems for Contextual AwarenessAn enterprise AI system needs to maintain contextual information over...

The selected option specifically B states “Implement a hybrid memory system with short-term memory for immediate context and a vector database for long-term memory with semantic retrieval capabilities.”, which matches the operational requirement rather than a superficial wording match. Hybrid memory is the right enterprise pattern: working context handles the current turn, vector memory retrieves relevant history. The context window alone is not a database. Option B fits the operating model because the problem describes an agent that must remain adaptive under changing inputs and infrastructure conditions. This lines up with NVIDIA guidance because agentic workflows need explicit state management; external memory complements the LLM context window while fine-tuning encodes stable behaviors into model policy. That matters because external state stores combined with model adaptation when repeated behavior should become part of the policy. That is why the other options are traps: a single flat store cannot serve both low-latency conversational state and durable semantic recall equally well. The result is a system that can be benchmarked, traced, and revised without destabilizing the whole agent fabric.
