DP-300 Implement a secure environment Practice Question

This DP-300 practice question tests your understanding of implement a secure environment. 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.

You are a database administrator for a multinational corporation that uses Azure SQL Managed Instance to host multiple databases for different business units. The security policy requires that all connections to the managed instance must use encrypted connections (TLS 1.2 or higher). Additionally, the company wants to minimize the attack surface by restricting network access. You need to configure the managed instance to enforce encrypted connections and block all public internet traffic. 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.

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

Set the 'Minimal TLS Version' property to 1.2 and set 'Public data endpoint' to 'Disabled'

Option A is correct because setting the 'Minimal TLS Version' property to 1.2 enforces that all connections use TLS 1.2 or higher, meeting the encryption requirement. Disabling the 'Public data endpoint' blocks all public internet traffic, ensuring that only traffic from within the virtual network can reach the managed instance. This combination directly satisfies both security policy goals without relying on additional components like private endpoints or firewall rules.

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.

  • Set the 'Minimal TLS Version' property to 1.2 and set 'Public data endpoint' to 'Disabled'

    Why this is correct

    This enforces TLS 1.2 or higher and blocks public internet traffic.

    Clue confirmation

    The clue word "minimum / minimize" in the question point toward this answer.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Enable a private endpoint and set the 'Minimal TLS Version' property to 1.0

    Why it's wrong here

    TLS 1.0 is not secure and does not meet the requirement for TLS 1.2 or higher.

  • Disable the public endpoint and enable a service endpoint for the virtual network

    Why it's wrong here

    Service endpoints provide connectivity but do not enforce TLS encryption.

  • Configure a server-level firewall rule to allow only specific IP addresses and set the 'Minimal TLS Version' property to 1.2

    Why it's wrong here

    Firewall rules control which IPs can connect, but the public endpoint remains enabled, increasing the attack surface.

Common exam traps

Common exam trap: answer the scenario, not the keyword

The trap here is that candidates often confuse disabling the public endpoint with using a private endpoint or firewall rules, failing to realize that both the TLS version enforcement and public endpoint disablement are required to fully meet the security policy.

Detailed technical explanation

How to think about this question

Azure SQL Managed Instance's 'Minimal TLS Version' property enforces the lowest TLS version accepted for client connections, rejecting any connection attempt using a lower version. Disabling the public endpoint removes the public IP address and DNS name, making the instance accessible only via the private endpoint or within the virtual network, which effectively eliminates internet-based attack vectors. This configuration is independent of firewall rules, which only filter traffic at the network layer and do not control encryption protocol versions.

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.

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 company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.
