DP-300 Implement a secure environment Practice Question

This DP-300 practice question tests your understanding of implement a secure environment. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.

You are a database administrator for a healthcare company. You have an Azure SQL Database that stores patient records. The database is currently accessible from the public internet via firewall rules. You need to implement a secure environment that meets the following requirements: - All traffic to the database must be private and not traverse the internet. - The database must be accessible from an Azure Virtual Machine in a specific VNet. - The solution must minimize management overhead and cost. - You need to ensure that the database can be failed over to a secondary region in case of an outage.

What should you do?

Clue words in this question

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

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.

A
Restrict firewall rules to only the VM's public IP and enable active geo-replication.
Why wrong: Traffic still goes over the internet, violating the private traffic requirement.
B
Configure a point-to-site VPN from the VM to the database and set up geo-replication.
Why wrong: VPN adds overhead and is not the recommended method for private connectivity.
C
Create a private endpoint in the VNet, disable public network access, and configure a failover group with a private endpoint in the secondary region.
This ensures private connectivity and disaster recovery.
D
Create a VNet service endpoint and a failover group. Keep public access enabled for failover.
Why wrong: Service endpoints do not make traffic completely private; the public endpoint remains.

Correct answer & explanation

✓

Create a private endpoint in the VNet, disable public network access, and configure a failover group with a private endpoint in the secondary region.

Option C is correct because it meets all requirements: a private endpoint ensures all traffic to the database stays within the Microsoft backbone network and never traverses the internet. Disabling public network access enforces that no public traffic can reach the database, fulfilling the private traffic requirement. Configuring a failover group with a private endpoint in the secondary region provides geo-replication and automatic failover while maintaining private connectivity, with minimal management overhead and no additional cost for VPNs. Option A is incorrect because restricting the firewall to the VM's public IP still allows traffic over the public internet, violating the private traffic requirement. Option B is incorrect because a point-to-site VPN adds complexity and cost, and still uses a VPN connection that may traverse the internet, and does not provide the same seamless private connectivity as a private endpoint. Option D is incorrect because a VNet service endpoint does not make traffic private; it still uses the public endpoint of the database, and keeping public access enabled fails the requirement to disable public internet access.

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 startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
