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

✓

Full admin access to objects

The service account sa@project.iam.gserviceaccount.com is a Google Cloud IAM service account. When it is granted the 'Storage Admin' role (roles/storage.admin) at the project level, it gains full admin access to all buckets in the project, including the ability to create, delete, and manage objects. This role provides full control over objects, equivalent to 'Full admin access to objects'.

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.

  • ✓

    Full admin access to objects

    Why this is correct

    objectAdmin provides full control over objects.

    Related concept

    Read the scenario before looking for a memorised answer.

  • ✗

    Owner access

    Why it's wrong here

    Owner is a different role (roles/storage.legacyBucketOwner) not shown.

  • ✗

    Read-only access

    Why it's wrong here

    objectViewer is read-only, but the SA is not in that binding.

  • ✗

    No access

    Why it's wrong here

    The SA has objectAdmin role.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse 'Owner access' (a primitive role) with the specific IAM role that grants full admin access to objects, or they assume that a service account with a project-level role only has read access, missing that Storage Admin provides full object control.

Trap categories for this question

  • Command / output trap

    Owner is a different role (roles/storage.legacyBucketOwner) not shown.

Detailed technical explanation

How to think about this question

Under the hood, IAM roles are collections of permissions; the Storage Admin role includes permissions like storage.objects.create, storage.objects.delete, and storage.objects.update, which allow full object management. In a real-world scenario, if a service account is used by an application to upload and delete files, granting Storage Admin ensures it can perform all necessary operations without needing additional roles. This role does not grant bucket-level IAM policy management (which requires storage.buckets.setIamPolicy), but it does provide full object-level control.

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.
