VA-003 Explain encryption as a service Practice Question
This VA-003 practice question tests your understanding of explain encryption as a service. 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.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Listing keys in the transit engine
The policy shown in the exhibit grants 'create', 'update', 'delete', and 'deny' capabilities on the transit engine, but it does not include a 'list' capability. In Vault's transit secrets engine, listing keys requires the 'list' capability on the engine path. Without it, the operation will fail due to insufficient permissions, even though other key management operations are allowed.
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.
✗
Rotating the key mykey
Why it's wrong here
The policy includes update on `transit/keys/mykey/rotate`, so rotation is allowed.
✗
Decrypting data using the key mykey
Why it's wrong here
The policy includes create/update on transit/decrypt/mykey, so decryption is allowed.
✗
Encrypting data using the key mykey
Why it's wrong here
The policy includes create/update on transit/encrypt/mykey, so encryption is allowed.
✗
Deleting the key mykey
Why it's wrong here
The policy includes delete on `transit/keys/mykey`, so deletion is allowed.
✓
Listing keys in the transit engine
Why this is correct
Listing requires list capability on `transit/keys/`, which is not granted.

Common exam traps
Common exam trap: answer the scenario, not the keyword
HashiCorp often tests the distinction between key-level operations (encrypt, decrypt, rotate, delete) and path-level operations (list), where candidates mistakenly assume that having 'create' or 'update' on keys implies the ability to list them.
Detailed technical explanation
How to think about this question
In HashiCorp Vault, the transit secrets engine uses capabilities like 'create', 'read', 'update', 'delete', and 'list' to control access. The 'list' capability is required to enumerate keys under a path, and it is distinct from other operations. For example, a policy allowing 'create' and 'update' on 'transit/keys/*' permits key creation and rotation but not listing all keys, which requires 'list' on 'transit/keys/'.

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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
