MLA-C01 Deployment and Orchestration of ML Workflows Practice Question
This MLA-C01 practice question tests your understanding of deployment and orchestration of ml workflows. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 data science team deploys a TensorFlow model for real-time inference using the Amazon SageMaker model configuration shown. They observe high latency during the first few requests after deployment. Which TWO actions would reduce cold start latency? (Choose two.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure a Production Variant with an initial instance count greater than zero
Options C and D are correct. Using Multi-Model Endpoints allows the endpoint to stay warm and reduces the time to load a model on demand. Setting an initial instance count greater than zero ensures that the endpoint always has at least one instance running, eliminating cold starts. Option A (adding another container) increases cold start latency. Option B (changing environment variable) does not affect model loading time. Option E (data capture) adds overhead without reducing cold start latency.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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 data capture on the endpoint
Why it's wrong here
Data capture adds overhead and does not reduce cold start latency.
✗
Set the SAGEMAKER_PROGRAM environment variable to a more optimized entry point
Why it's wrong here
Changing the environment variable does not affect the time to load the model or start the container.
✗
Add a secondary container for model ensemble
Why it's wrong here
Adding another container increases the cold start latency as more containers need to be initialized.
✓
Configure a Production Variant with an initial instance count greater than zero
Why this is correct
Setting an initial instance count ensures that instances are always running, preventing cold start.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✓
Use Amazon SageMaker Multi-Model Endpoints
Why this is correct
Multi-Model Endpoints keep the endpoint running and cache models, reducing cold start for subsequent invocations.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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. NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related MLA-C01 NAT questions on configuration and troubleshooting.
