How to Grant Permissions to Compute Instances Without Long-Term Keys

This SSCP practice question tests your understanding of systems and application security. 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. A key principle to apply: iAM Role. 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.

An organization using cloud IAM wants to grant a compute instance permissions to access a cloud storage bucket without storing long-term credentials on the instance. Which IAM feature should be used?

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

IAM role assigned to the compute instance

IAM roles for compute instances allow the instance to assume a role and obtain temporary credentials from a security token service, avoiding the need for long-term keys.

Key principle: IAM Role

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • IAM role assigned to the compute instance

    Why this is correct

    Correct: IAM roles provide temporary credentials to compute instances, eliminating the need for long-term keys and enhancing security.

  • Service-level access policies

    Why it's wrong here

    Incorrect: Service-level access policies, such as service control policies, are used to manage permissions at an organizational level, not to grant per-instance access to storage.

  • Long-term user access keys

    Why it's wrong here

    Incorrect: Long-term user access keys would be stored on the instance, which contradicts the requirement to avoid storing long-term credentials.

  • Resource-based policies on the storage bucket

    Why it's wrong here

    Incorrect: Resource-based policies on the storage bucket control access from any principal, but they do not provide temporary credentials to the instance without a role.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Detailed technical explanation

How to think about this question

Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.

KKey Concepts to Remember

  • IAM Role
  • Temporary Credentials

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

IAM Role

Real-world example

How this comes up in practice

A developer is choosing between AES-256 (symmetric) and RSA-2048 (asymmetric) for encrypting a large file that will be sent to a partner. Symmetric encryption is fast but requires key exchange; asymmetric is slower but solves the key distribution problem. A hybrid approach — encrypt the file with AES, encrypt the AES key with RSA — is standard. Questions like this test whether you understand when each approach applies.
