AIF-C01 Practice Question: Deploying a generative AI application using…
This AIF-C01 practice question tests your understanding of aif-c01 exam topics. 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 company is deploying a generative AI application using Amazon Bedrock and needs to optimize costs. They expect variable traffic with occasional high spikes. Which TWO strategies would help reduce costs while maintaining performance?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Enable model caching to serve repeated prompts without re-inference
Model caching reduces cost for repeated queries, and batch inference is cheaper for non-real-time workloads. Provisioned throughput is expensive and not cost-optimal for variable traffic. Fine-tuning and using the largest model increase costs.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Enable model caching to serve repeated prompts without re-inference
Why this is correct
Caching avoids repeated computation for identical requests.
Related concept
Authentication checks who the user is.
✓
Use on-demand inference with batch processing for non-real-time requests
Why this is correct
Batch inference is cheaper than real-time for asynchronous tasks.
Related concept
Authentication checks who the user is.
✗
Always use the largest available foundation model for quality
Why it's wrong here
Larger models are more expensive; right-sizing is better.
✗
Use provisioned throughput to handle spikes
Why it's wrong here
Provisioned throughput guarantees capacity but is costly; not cost-optimal for variable traffic.
✗
Fine-tune a larger model for better accuracy
Why it's wrong here
Fine-tuning and larger models increase cost.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
Authentication checks who the user is.
Authorization controls what the user is allowed to do after login.
Privilege levels affect access to EXEC and configuration commands.
AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
→Do not assume successful login means full administrative access.
→Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
→Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
What to study next
Got this wrong? Here's your next step.
Review Cisco AAA concepts — authentication, authorization, and accounting. Study privilege levels (0–15), command authorization under TACACS+, and how RADIUS differs. Then practise related AIF-C01 questions on access control and AAA configuration.
The correct answer is: Enable model caching to serve repeated prompts without re-inference — Model caching reduces cost for repeated queries, and batch inference is cheaper for non-real-time workloads. Provisioned throughput is expensive and not cost-optimal for variable traffic. Fine-tuning and using the largest model increase costs.
