Google PCA Ensure solution and operations reliability Practice Question
This PCA practice question tests your understanding of ensure solution and operations reliability. 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.
Network Topology
A developer ran the above command to create a health check for a backend service. Which of the following should they do to resolve the error?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a different name for the health check.
Option E is correct because the error indicates that a health check with the same name already exists for the load balancer. In AWS, health check names must be unique within a load balancer. By using a different name, the developer can create a new health check without conflicting with the existing one.
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.
✗
Change the request-path to a different value.
Why it's wrong here
Changing path does not resolve the name conflict.
✗
Delete the existing health check and recreate it.
Why it's wrong here
Deleting may cause disruption if the health check is in use.
✗
Add the --global flag to the command.
Why it's wrong here
Health checks are already global by default.
✗
Use --load-balancer-type internal to create a new health check with the same name.
Why it's wrong here
Load balancer type does not affect health check name uniqueness.
✓
Use a different name for the health check.
Why this is correct
Using a different name resolves the conflict without disruption.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that modifying parameters like request-path or load balancer type can resolve naming conflicts, when in fact the core issue is a duplicate name that must be changed.
Detailed technical explanation
How to think about this question
AWS Elastic Load Balancing requires health check names to be unique per load balancer. The error occurs when a health check with the same name already exists, often due to a previous creation attempt or a misconfiguration. Under the hood, the AWS API enforces this uniqueness constraint to prevent ambiguity in health check routing and monitoring.

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.
