- A
Use Cloud Vision API to extract text from the image, then send that text to a text‑only model
Why wrong: This approach loses the visual context and may not capture plant characteristics.
- B
Use Vertex AI Agent Builder with a text‑only model and ignore the image
Why wrong: This ignores the user's photo input, failing to meet the requirement.
- C
Use Gemini on Vertex AI with a prompt that includes the image and the user’s question
Gemini natively handles image and text inputs, so a single prompt can process the photo and answer the question.
- D
Use Imagen to generate a description of the plant, then feed that description to a text model
Why wrong: Imagen generates images from text, not descriptions from images — the wrong direction.

Generative AI Leader Generative AI Concepts and Technologies Practice Question
This Generative AI Leader practice question tests your understanding of generative ai concepts and technologies. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A startup is building a multimodal application that allows users to upload a photo of a plant and ask questions about its care. They want to use Google Cloud generative AI services. Which combination of services is MOST suitable?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use Gemini on Vertex AI with a prompt that includes the image and the user’s question
Option C is correct because Gemini on Vertex AI natively supports multimodal inputs, allowing the model to directly process the uploaded plant image alongside the user's care question in a single prompt. This eliminates the need for intermediate text extraction or image description generation, providing the most accurate and context-aware response for the application's requirements.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that multimodal tasks require separate vision and language models chained together, when in fact a single multimodal model like Gemini can handle both modalities natively, offering superior accuracy and simplicity.
Detailed technical explanation
How to think about this question
Gemini on Vertex AI uses a multimodal transformer architecture that fuses visual and textual tokens in a shared embedding space, enabling joint reasoning over the image and question without separate preprocessing. This approach leverages attention mechanisms to correlate specific image regions (e.g., leaf discoloration) with the user's query, producing responses that consider both visual cues and textual intent. In practice, this means the model can identify a plant's species from the photo and provide tailored care instructions, which is impossible with unimodal pipelines.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
