- A
Enable the 'Allow Azure services and resources to access this server' firewall setting.
Why wrong: This allows all Azure services, including those outside your subscription, which is a security risk.
- B
Use VNet service endpoints instead of Private Link to reduce costs.
Why wrong: Service endpoints still expose the database to the public endpoint, though restricted to the VNet.
- C
Use Azure Private Link to connect to the database from a virtual network.
Private Link provides a private IP address within the VNet, eliminating exposure to the internet.
- D
Disable public network access on the SQL server.
This ensures only private endpoint connections are allowed.
- E
Add firewall rules that allow all IP addresses from your organization's IP range.
Why wrong: Allowing a large IP range increases attack surface; use the most restrictive rules.
Quick Answer
The answer is to disable public network access on the SQL server and use Azure Private Link. These two practices work together to enforce network security best practices for Azure SQL Database by ensuring that all traffic to your database is routed through a private endpoint within your virtual network, completely bypassing the public internet. Disabling public access at the server level acts as a master kill switch, blocking any inbound traffic that isn’t explicitly allowed through a private endpoint, while Private Link provides a secure, dedicated connection that eliminates exposure to the open web. On the Microsoft Azure Database Administrator Associate DP-300 exam, this question tests your understanding of modern network isolation versus legacy methods; a common trap is selecting “Allow Azure services” or VNet service endpoints, which are broader and less secure than Private Link. Remember the memory tip: “Private Link, public sink” — if you want true security, lock down public access and link privately.
DP-300 Implement a secure environment Practice Question
This DP-300 practice question tests your understanding of implement a secure environment. 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.
You are designing a secure environment for Azure SQL Database. Which TWO of the following are recommended practices for network security?
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
Use Azure Private Link to connect to the database from a virtual network.
Options A and C are correct. Azure Private Link ensures traffic never traverses the public internet. Disabling public network access at the server level blocks all internet traffic. Option B is wrong because allowing all Azure services is a broad rule that may be insecure. Option D is wrong because VNet service endpoints are legacy and less secure than Private Link. Option E is wrong because firewall rules with large IP ranges are less secure.
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.

Same concept, more angles
2 more ways this is tested on DP-300
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. You are setting up Azure SQL Database and need to ensure that only specific Azure services (e.g., Azure Data Factory) can access the database. What should you configure?
easy- A.Create a private endpoint for the database.
- B.Add firewall rules for the public IP addresses of the Azure services.
- C.Add a firewall rule with start and end IP set to 0.0.0.0.
- ✓ D.Add a virtual network rule for the subnet where the service is deployed.
Why D: Option D is correct because a virtual network rule allows you to restrict access to your Azure SQL Database to traffic originating from a specific virtual network subnet. When Azure services like Azure Data Factory are deployed in a virtual network, you can create a virtual network rule that references the subnet of that service, ensuring only traffic from that subnet can connect. This provides a more secure and granular access control compared to IP-based firewall rules, as it leverages the Azure backbone network and avoids exposing the database to public IP ranges.
Variation 2. Your organization has an Azure SQL Database server. You need to ensure that only applications running on Azure virtual machines in a specific virtual network can connect to the database. Which THREE actions should you take?
hard- A.Add a service endpoint for Azure SQL Database to the virtual network.
- ✓ B.Add a virtual network rule for the specific subnet of the VMs.
- ✓ C.Set the 'Allow Azure Services and resources to access this server' setting to OFF.
- ✓ D.Remove all existing firewall rules that allow public IP ranges.
- E.Set the 'Allow Azure Services and resources to access this server' setting to ON.
Why B: Option B is correct because adding a virtual network rule for the specific subnet of the VMs allows Azure SQL Database to accept traffic only from that subnet when a service endpoint is enabled. This restricts access to the database to only those applications running on Azure VMs within the specified virtual network, ensuring network-level isolation.
