- A
Implement API key authentication
API keys restrict access to authorised clients.
- B
Enable content filtering
Why wrong: Content filtering moderates outputs but does not secure access or control costs.
- C
Disable logging to reduce storage costs
Why wrong: Disabling logging may save storage but compromises security auditing and debugging.
- D
Apply rate limiting per user
Rate limiting prevents excessive usage, controlling costs and ensuring fair access.
- E
Use gRPC instead of REST
Why wrong: gRPC is a protocol choice that does not inherently improve security or cost control.

AI0-001 AI Infrastructure and Technologies Practice Question
This AI0-001 practice question tests your understanding of ai infrastructure 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.
An organisation is deploying a fine-tuned LLM for internal use. They need to ensure the API endpoint is secure and cost-effective. Which TWO measures should they implement? (Choose 2)
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
✓
Implement API key authentication
API key authentication (Option A) is a fundamental security measure that ensures only authorized clients can access the LLM endpoint. It provides a simple, lightweight mechanism to validate requests without the overhead of full OAuth, making it both secure and cost-effective for internal deployments.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Why it's wrong here
Disabling logging may save storage but compromises security auditing and debugging.
- ✓
Apply rate limiting per user
Why this is correct
Rate limiting prevents excessive usage, controlling costs and ensuring fair access.

Why it's wrong here
gRPC is a protocol choice that does not inherently improve security or cost control.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between security measures (authentication, rate limiting) and non-security features (content filtering, protocol choice), leading candidates to mistakenly select content filtering or gRPC as security controls.
Trap categories for this question
Command / output trap
Content filtering moderates outputs but does not secure access or control costs.
Detailed technical explanation
How to think about this question
API key authentication works by including a secret key in the HTTP header (e.g., 'Authorization: Bearer <key>'), which the server validates against a stored hash. Rate limiting (Option D) typically uses token bucket or leaky bucket algorithms to cap requests per user (e.g., 100 requests/minute), preventing abuse and controlling cloud API costs by throttling excessive usage. Together, these measures provide a dual layer of access control and cost governance without requiring expensive identity providers.
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 practitioner preparing for the AI0-001 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
