The correct answer is that enabling infrastructureEncryption adds a second layer of encryption at the infrastructure level, ensuring data is encrypted at rest with two different keys. This is known as double encryption, where Azure Synapse first encrypts data using service-managed keys at the logical layer, and then a separate hardware-backed encryption key encrypts the underlying storage infrastructure. On the DP-203 exam, this concept tests your understanding of defense-in-depth for data at rest, often appearing as a configuration option in ARM templates or Azure Portal settings. A common trap is confusing this with encryption in transit or assuming it disables existing encryption; in reality, it layers an additional physical-level cipher. Remember the memory tip: “Two keys, two layers—infrastructure encryption doubles your data’s stayers.”
DP-203 Practice Question: Secure, monitor, and optimize data storage and data processing
This DP-203 practice question tests your understanding of secure, monitor, and optimize data storage and data processing. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Refer to the exhibit. You are deploying an Azure Synapse Analytics workspace using an ARM template. The exhibit shows the encryption configuration. What is the effect of setting infrastructureEncryption to Enabled?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
It adds a second layer of encryption at the infrastructure level, ensuring data is encrypted at rest with two different keys.
Option D is correct because infrastructure encryption (double encryption) encrypts data at both the service level and the infrastructure level. Option A is wrong because it encrypts at rest, not in transit. Option B is wrong because it does not disable encryption; it adds another layer. Option C is wrong because it's not for logs.
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.
✗
It disables encryption using the customer-managed key.
Why it's wrong here
It enables additional encryption, not disables it.
✗
It enables encryption of data in transit between nodes.
Why it's wrong here
Infrastructure encryption is for at-rest data, not in-transit.
✗
It enables transparent data encryption for SQL pools.
Why it's wrong here
Infrastructure encryption is a storage-level feature, not specific to SQL pools.
✓
It adds a second layer of encryption at the infrastructure level, ensuring data is encrypted at rest with two different keys.
Why this is correct
Infrastructure encryption provides double encryption for data at rest.

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.

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 cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
