The answer is yes, Alice will succeed because the Cloud SQL Auth proxy uses IAM permissions for authentication and authorization, and the `cloudsql.client` role grants the `cloudsql.instances.connect` permission unconditionally. Even though a condition on the `cloudsql.admin` role restricts the `cloudsql.instances.update` permission to only 'dev' instances, that condition does not apply to the connect permission, so the client role’s unconditional access prevails. On the Google Professional Cloud Security Engineer exam, this scenario tests your understanding of how IAM roles and conditions interact with the Cloud SQL Auth proxy—a common trap is assuming a condition on one permission blocks all actions for that role. Remember, IAM conditions are permission-specific, not role-wide. Memory tip: "Client connects unconditionally; admin conditions only update."
PCSE Practice Question: Configuring access within a cloud solution environment
This PCSE practice question tests your understanding of configuring access within a cloud solution environment. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
Exhibit
The following IAM policy was applied on a project:
bindings:
- members:
- user: alice@example.com
role: roles/cloudsql.admin
condition:
expression: "resource.name.startsWith('projects/PROJECT_ID/instances/dev-')"
title: "dev_only"
- members:
- user: alice@example.com
role: roles/cloudsql.client
condition: {}
Alice tries to connect to Cloud SQL instance 'prod-instance' using the Cloud SQL Auth proxy. Will she succeed? Why?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Yes, because the admin role grants full access, and the condition only applies to the admin role, but the client role is unconditional.
Option B is correct because the Cloud SQL Auth proxy uses IAM permissions for authentication and authorization. The `cloudsql.client` role grants the `cloudsql.instances.connect` permission unconditionally, allowing Alice to connect to any instance. The `cloudsql.admin` role's condition restricting access to 'dev' instances only applies to the `cloudsql.instances.update` permission, not to the connect permission, so the client role's unconditional access prevails.
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.
✗
Yes, because she has the client role with no condition.
Why it's wrong here
While the client role is unconditional, the statement is incomplete as it doesn't explain why the admin condition doesn't override.
✓
Yes, because the admin role grants full access, and the condition only applies to the admin role, but the client role is unconditional.
Why this is correct
The unconditional client role provides the necessary permissions to connect.

Read the scenario before looking for a memorised answer.
✗
No, because the admin role condition overrides the client role.
Why it's wrong here
Roles are additive; conditions on one role do not restrict other unconditional roles.
✗
No, because the cloudsql.admin role condition restricts to dev instances only.
Why it's wrong here
The client role is separate and not affected by the condition on the admin role.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Google Cloud often tests the misconception that a restrictive condition on a higher-privilege role (like admin) overrides a lower-privilege role (like client), when in reality IAM evaluates each permission independently and the most permissive effective permission wins.
Detailed technical explanation
How to think about this question
The Cloud SQL Auth proxy uses IAM to authenticate via the `cloudsql.instances.connect` permission, which is included in both the `cloudsql.client` and `cloudsql.admin` roles. IAM conditions are evaluated per permission; a condition on `cloudsql.admin` only affects permissions that are explicitly listed in the condition's resource or attribute scope. In this case, the condition restricts `cloudsql.instances.update` to 'dev' instances, but `cloudsql.instances.connect` remains unrestricted for the client role. The proxy also validates the IAM principal's email against the instance's authorized networks or IAM database authentication, but the core access decision is based on effective IAM permissions.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.

What is the correct answer to this question?
The correct answer is: Yes, because the admin role grants full access, and the condition only applies to the admin role, but the client role is unconditional. — Option B is correct because the Cloud SQL Auth proxy uses IAM permissions for authentication and authorization. The `cloudsql.client` role grants the `cloudsql.instances.connect` permission unconditionally, allowing Alice to connect to any instance. The `cloudsql.admin` role's condition restricting access to 'dev' instances only applies to the `cloudsql.instances.update` permission, not to the connect permission, so the client role's unconditional access prevails.
