Quick Answer
The answer is storage.objects.get and storage.objects.delete. These two permissions are required because downloading an object requires reading its data and metadata, which is governed by the get permission, while deleting an object requires the delete permission to authorize its removal from the bucket. On the Google Professional Cloud Security Engineer exam, this question tests your understanding of the principle of least privilege within Cloud Storage IAM, where custom role permissions must be granular and specific to the action. A common trap is confusing storage.objects.get with storage.objects.list, but list only allows viewing object names, not downloading the actual content. Another trap is assuming storage.buckets.delete is needed, but that removes the entire bucket, not individual objects. For a memory tip, think of the acronym G-D: Get for Download, Delete for removal—two distinct actions requiring two distinct permissions.
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 user should be able to download and delete objects in a specific Cloud Storage bucket. Which two permissions are required in a custom role? (Choose two.)
storage.buckets.list
Why wrong: This permission is for listing buckets, not objects.
storage.objects.delete
Required to delete objects.
storage.buckets.get
Why wrong: This permission is for viewing bucket metadata, not objects.
storage.objects.list
Why wrong: Required for listing objects, but not for downloading or deleting.
storage.objects.get
Required to download (read) objects.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
storage.objects.delete
To download an object, the user needs `storage.objects.get` permission, which allows reading the object's data and metadata from the bucket. To delete an object, the user needs `storage.objects.delete` permission, which authorizes the removal of the object from the bucket. These two permissions are the minimum required for download and delete operations on objects within a specific Cloud Storage bucket.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Google Cloud often tests the distinction between object-level permissions (like `storage.objects.get` and `storage.objects.delete`) and bucket-level permissions (like `storage.buckets.list` or `storage.buckets.get`), trapping candidates who assume listing or getting bucket metadata is necessary for object operations.
Detailed technical explanation
Under the hood, Cloud Storage IAM permissions map to specific REST API calls: `storage.objects.get` corresponds to the `GET` request on an object resource (e.g., `/b/{bucket}/o/{object}`), while `storage.objects.delete` maps to the `DELETE` method on the same endpoint. A real-world scenario where this distinction matters is when granting a support engineer the ability to view and remove corrupted files without exposing the ability to list all objects, which could leak sensitive filenames.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
