Question 187 of 1,738
Data ProtectionhardMultiple ChoiceObjective-mapped

Quick Answer

The correct answer is to create a custom key store in AWS KMS backed by an AWS CloudHSM cluster, then use a KMS key from that store to encrypt the Redshift cluster. This satisfies the auditor’s demand because a custom key store lets you control the underlying HSM hardware, keeping key material exclusively in your own CloudHSM cluster while still leveraging KMS for integration with Redshift. On the AWS Certified Security Specialty SCS-C02 exam, this scenario tests your understanding that Redshift cannot directly use CloudHSM—it must go through KMS, and a custom key store bridges that gap. A common trap is choosing direct CloudHSM integration or importing key material, but those either lack Redshift support or still leave key material in KMS. Remember: for Redshift encryption with your own HSM, think “KMS custom key store + CloudHSM” as the only path. Memory tip: “Custom store, HSM floor—Redshift keys, yours to secure.”

SCS-C02 Data Protection Practice Question

This SCS-C02 practice question tests your understanding of data protection. 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 is migrating its on-premises data warehouse to AWS. The data includes highly sensitive customer financial information. The company has the following requirements: 1) All data must be encrypted at rest using a key that is managed by the company's internal security team. 2) The encryption keys must be rotated every 90 days. 3) The data warehouse must support SQL queries and be highly available across multiple Availability Zones. 4) The solution must minimize the administrative overhead of managing keys. The security team has chosen Amazon Redshift as the data warehouse. They have enabled encryption using AWS KMS with a customer-managed key (CMK). They have set the key rotation period to 90 days using automatic key rotation. However, during a security review, an auditor points out that the key material is still stored in AWS KMS, and the company wants the key material to be stored in a hardware security module (HSM) that they control. Which of the following is the BEST course of action to meet the auditor's requirement while maintaining the other requirements?

Clue words in this question

Noticing these words before you look at the options changes how you read each choice.

  • Clue: "best"

    Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.

  • Clue: "minimum / minimize"

    Why it matters: Asks for the least resource use — fewest addresses, smallest subnet, lowest overhead. Eliminate over-provisioned options even if they would technically work.

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

Create a custom key store in AWS KMS backed by an AWS CloudHSM cluster, and use a KMS key in that custom key store to encrypt the Redshift cluster.

Option C is correct because using a custom key store backed by AWS CloudHSM allows the company to store key material in their own HSM, and automatic key rotation can still be used (though manual rotation may be needed depending on the HSM). Redshift supports encryption with KMS, including custom key stores. Option A is wrong because SSE-C is for S3, not Redshift. Option B is wrong because Redshift does not support CloudHSM directly; it requires KMS custom key store. Option D is wrong because importing key material does not allow the company to control the HSM; the key material is still stored in KMS.

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.

  • Use AWS CloudHSM directly to generate and manage the encryption keys, and configure Redshift to use those keys via the CloudHSM client.

    Why it's wrong here

    Redshift does not support direct integration with CloudHSM; it only supports KMS.

  • Create a custom key store in AWS KMS backed by an AWS CloudHSM cluster, and use a KMS key in that custom key store to encrypt the Redshift cluster.

    Why this is correct

    This allows the company to control the HSM and store key material in it, while Redshift uses KMS for encryption.

    Clue confirmation

    The clue words "best", "minimum / minimize" in the question point toward this answer.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Switch to using Amazon S3 server-side encryption with customer-provided keys (SSE-C) and use Redshift Spectrum to query the data.

    Why it's wrong here

    SSE-C is for S3, not Redshift. Redshift Spectrum can query S3, but the primary data warehouse would not be encrypted with the company's HSM.

  • Generate the key material on-premises and import it into KMS as a customer-managed key, then use that key for Redshift encryption.

    Why it's wrong here

    Imported key material is stored in KMS, not in the company's HSM. The company does not have control over the HSM.

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

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

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.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • 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.
