Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A financial services company runs a critical trading application in its on-premises data center. The company is migrating some workloads to Azure and requires a dedicated, private network connection between its on-premises network and Azure. The connection must not use the public internet, must provide consistent latency and higher bandwidth than a typical internet-based VPN, and must be backed by a service-level agreement (SLA) for availability. Which Azure service should the company use to meet these requirements?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Azure VPN Gateway
Azure VPN Gateway creates an encrypted tunnel over the public internet. While it provides a secure connection, it does not offer a private connection that bypasses the public internet, and bandwidth and latency are typically lower and less consistent than ExpressRoute.
B
Best answer
ExpressRoute
ExpressRoute provides a dedicated private connection from on-premises to Azure that does not use the public internet. It offers higher bandwidth, lower and consistent latency, and an availability SLA, meeting all the stated requirements.
C
Distractor review
Azure Firewall
Azure Firewall is a managed network security service that helps protect Azure virtual network resources. It does not provide a connectivity service between on-premises and Azure.
D
Distractor review
Azure Front Door
Azure Front Door is a global load balancer and content delivery network that operates over the public internet. It is designed for web applications and does not provide a private dedicated connection between an on-premises network and Azure.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this AZ-900 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: ExpressRoute — ExpressRoute is the correct choice because it provides a private, dedicated connection from on-premises to Azure that does not traverse the public internet, offers lower and consistent latency, higher bandwidth, and is backed by an SLA. Azure VPN Gateway is IPsec-based and uses the public internet, so it does not meet the requirement for a private connection that avoids the public internet. Azure Firewall is a managed network security service and does not provide connectivity. Azure Front Door is a global entry point for web applications that provides load balancing and acceleration over the internet, not a private dedicated connection.
