- A
Update the Event Hubs namespace to require TLS 1.2, then modify the Databricks streaming job's connection string to include 'TransportType=AmqpTls' and restart the streaming job.
Enforces TLS 1.2 with minimal disruption.
- B
Change the Event Hubs namespace minimum TLS version to 1.2 in the Azure portal, then reboot the Databricks cluster.
Why wrong: Rebooting doesn't update connection settings.
- C
In the Event Hubs namespace, set 'Minimum TLS version' to 1.2 and redeploy the Databricks cluster with a new init script that forces TLS 1.2.
Why wrong: Redeployment causes disruption.
- D
Use Azure CLI to set the Event Hubs namespace TLS version to 1.2 and update the Databricks cluster's Spark configuration to use TLS 1.2.
Why wrong: Missing restart of streaming job.
Quick Answer
The answer is to update the Event Hubs namespace to enforce TLS 1.2 as the minimum version, then modify the Databricks streaming job’s connection string to include TransportType=AmqpTls and restart the job. This is correct because enforcing TLS 1.2 on the Event Hubs side blocks older protocol handshakes, while the AmqpTls transport type in the connection string forces the Databricks client to use AMQP over TLS 1.2, ensuring end-to-end encryption for data in transit. On the DP-203 exam, this scenario tests your understanding of securing streaming pipelines by aligning Azure service-side TLS policies with client-side connection configurations—a common trap is only updating the Event Hubs namespace and forgetting to adjust the Databricks connection string, which leaves the stream using the default TLS 1.0. Remember the two-step rule: lock the service, then lock the client. A useful mnemonic is “Hub locks, Spark clocks”—update the Hub’s TLS minimum, then clock the Spark connection string with AmqpTls.
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.
Contoso Ltd. runs a real-time analytics solution on Azure Databricks with data streaming from Event Hubs. They need to ensure that all data in transit between Event Hubs and Databricks is encrypted using TLS 1.2 or higher. Currently, the Event Hubs namespace is configured with the default TLS version (1.0). The Databricks cluster uses a public endpoint. Compliance requires that only TLS 1.2 is accepted. You need to configure the environment to enforce TLS 1.2 without disrupting ongoing streaming. What should you do?
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
Update the Event Hubs namespace to require TLS 1.2, then modify the Databricks streaming job's connection string to include 'TransportType=AmqpTls' and restart the streaming job.
Step 1: Update the Event Hubs namespace to require TLS 1.2 via 'Minimum TLS version' setting. Step 2: Configure the Databricks cluster to connect using TLS 1.2 by setting spark.conf to 'spark.eventhubs.connectionString' with TLS parameter. Step 3: Restart the streaming job to apply new connection settings. Option D includes all steps in order. Option A reboots without config change. Option B uses Azure CLI but doesn't cover Databricks. Option C only updates Event Hubs but not Databricks.
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
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 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.
