Security ArchitecturemediumMultiple ChoiceObjective-mapped

Quick Answer

The answer is configuring least-privilege IAM roles, bucket policies, and object permissions for approved users only. This is correct because, while encryption at rest and physical security protect data from external breaches and media theft, they do nothing to control what an authenticated user can access; overly permissive IAM policies create a wide attack surface where authorized users—or compromised credentials—can reach files they should not see. On the Security+ SY0-701 exam, this question tests your understanding that access control is a separate, essential layer from encryption, and a common trap is to assume encryption alone prevents unauthorized access by insiders. Remember the memory tip: "Encryption locks the box, but least privilege locks the key."

SY0-701 Security Architecture Practice Question

This SY0-701 practice question tests your understanding of security architecture. 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 company stores customer documents in cloud object storage. The provider already offers encryption at rest and physical security. Which action most directly reduces the risk of unauthorized access to the stored files?

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

Configure least-privilege IAM roles, bucket policies, and object permissions for approved users only.

Option C is correct because, even with encryption at rest and physical security, unauthorized access can occur if IAM policies, bucket policies, and object permissions are overly permissive. Configuring least-privilege access ensures that only approved users can read or modify the stored files, directly reducing the attack surface. Encryption at rest protects data if storage media is compromised, but it does not prevent authorized users with excessive permissions from accessing files they shouldn't.

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.

  • Assume the provider's default settings are sufficient because encryption at rest is already enabled.

    Why it's wrong here

    Default settings often do not enforce least privilege or restrict who can read the objects.

  • Move the documents to a public bucket so users can access them without friction.

    Why it's wrong here

    Public access increases exposure and contradicts the goal of reducing unauthorized access risk.

  • Configure least-privilege IAM roles, bucket policies, and object permissions for approved users only.

    Why this is correct

    Access control is the customer's main responsibility here, and least-privilege permissions directly limit who can retrieve the files.

  • Disable encryption at rest so administrators can troubleshoot access problems more easily.

    Why it's wrong here

    Removing encryption weakens protection and does nothing to reduce unauthorized access risk.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates confuse encryption at rest with access control, assuming that encryption alone prevents unauthorized access, when in fact it only protects against physical theft of storage media, not against API-level access by users with excessive permissions.

Detailed technical explanation

How to think about this question

In cloud object storage (e.g., AWS S3, Azure Blob Storage), access control is enforced through a combination of IAM policies (user/role-level), bucket policies (resource-level), and object ACLs (object-level). Even with server-side encryption (SSE-S3 or SSE-KMS), a user with s3:GetObject permission can decrypt and read any object; encryption at rest only protects data at the storage layer, not against authorized API calls. A real-world scenario is the 2017 Accenture breach, where misconfigured S3 buckets exposed sensitive data despite encryption being enabled.

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 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.
