A
This key is a customer-managed encryption key (CMEK) but is stored in software.
Why wrong: ProtectionLevel HSM indicates hardware, not software.
B
This key is stored in a Hardware Security Module (HSM) and cannot be exported.
The HSM protection level means the key material resides in Cloud HSM and is non-exportable.
C
This key is an external key managed via Cloud EKM.
Why wrong: Cloud EKM keys show protectionLevel EXTERNAL.
D
This is a software key managed by Cloud KMS.
Why wrong: ProtectionLevel is HSM, not SOFTWARE.

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

✓

This key is stored in a Hardware Security Module (HSM) and cannot be exported.

The exhibit shows a Cloud KMS key with the purpose 'symmetric encryption' and the protection level 'HSM'. Keys with HSM protection level are stored in a Hardware Security Module, which provides tamper-resistant hardware-based key storage. Additionally, the key is marked as 'Cannot be exported', meaning the key material never leaves the HSM boundary, ensuring it cannot be extracted or copied. This matches the description of a key stored in an HSM that cannot be exported.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Google Cloud often tests the distinction between protection levels (software vs. HSM) and the concept of exportability, where candidates mistakenly assume that any key in Cloud KMS can be exported or that CMEK always implies software storage.

Trap categories for this question

Command / output trap
Cloud EKM keys show protectionLevel EXTERNAL.

Detailed technical explanation

How to think about this question

Cloud KMS supports three protection levels: software (keys stored in software, backed by FIPS 140-2 Level 1), HSM (keys stored in FIPS 140-2 Level 3 certified HSMs), and external (keys managed via Cloud EKM). When a key is created with HSM protection, the key material is generated and stored inside the HSM, and operations like encryption and signing occur within the HSM. The 'Cannot be exported' property is enforced by the HSM firmware; even with appropriate IAM permissions, the raw key material cannot be retrieved, which is critical for compliance with regulations like PCI DSS that require hardware-based key protection.

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.
