- A
Storage Legacy Bucket Writer (roles/storage.legacyBucketWriter)
This role allows listing buckets and creating/overwriting objects, but not deleting objects. It does not grant permission to delete or modify existing objects.
- B
Storage Object Viewer (roles/storage.objectViewer)
Why wrong: This role only allows reading objects, not creating or managing buckets.
- C
Storage Admin (roles/storage.admin)
Why wrong: This role grants full control over buckets and objects, including deletion.
- D
Storage Object Admin (roles/storage.objectAdmin)
Why wrong: This role grants full control over objects, including deletion and modification.

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.
A security engineer is configuring access for a new team member who needs to manage Cloud Storage buckets, but should not be able to delete or modify existing objects. Which IAM role should be assigned?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Storage Legacy Bucket Writer (roles/storage.legacyBucketWriter)
The Storage Legacy Bucket Writer role (roles/storage.legacyBucketWriter) allows a user to list, create, and update buckets, but it does not grant permissions to delete or modify existing objects within those buckets. This role is specifically designed for managing bucket-level metadata while restricting object-level write and delete operations, making it the correct choice for the described requirement.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between bucket-level and object-level roles, and the trap here is that candidates confuse 'bucket writer' with 'object writer,' assuming it allows object modification, when in fact it only affects bucket metadata and not the objects themselves.
Detailed technical explanation
How to think about this question
Under the hood, IAM roles in Google Cloud are collections of permissions; the Storage Legacy Bucket Writer role includes permissions like storage.buckets.get, storage.buckets.list, and storage.buckets.update, but explicitly excludes storage.objects.delete and storage.objects.update. In a real-world scenario, this role is ideal for a DevOps engineer who needs to configure bucket lifecycle policies or set up notifications without risking accidental deletion of critical data objects.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
