This MLA-C01 practice question tests your understanding of mla-c01 exam topics. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Create a new endpoint configuration with a second variant and update the endpoint
Option C is correct because it uses SageMaker's blue/green deployment pattern: creating a new endpoint configuration with a second variant (the new model version) and updating the endpoint shifts traffic gradually or instantly without downtime. This approach leverages the endpoint's ability to host multiple variants and route traffic between them, ensuring zero interruption during the update.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Delete the existing endpoint and create a new one
Why it's wrong here
This causes downtime during deletion and recreation.
✗
Update the endpoint's model name directly
Why it's wrong here
Endpoint configurations are immutable; you cannot change the model name in a deployed configuration.
✓
Create a new endpoint configuration with a second variant and update the endpoint
Why this is correct
This allows a blue/green deployment with zero downtime by shifting traffic gradually or instantly.

✗
Use SageMaker Model Monitor to automatically switch
Why it's wrong here
Model Monitor is for monitoring, not for updating endpoints.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse 'updating the endpoint' with 'modifying the existing configuration directly' (Option B), not realizing that SageMaker enforces immutability of endpoint configurations and requires a new configuration to change the model or variant.
Detailed technical explanation
How to think about this question
Under the hood, SageMaker endpoints use endpoint configurations that define one or more production variants, each with a model and instance type. When you call UpdateEndpoint with a new endpoint configuration, SageMaker performs a rolling update: it provisions the new variant, waits for it to become healthy, then shifts traffic from the old variant to the new one before decommissioning the old variant. This process respects the 'InitialInstanceCount' and 'InitialVariantWeight' settings, allowing fine-grained control over traffic shifting, such as canary deployments or linear ramp-ups.
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.
