- A
Azure Bastion
Correct. Azure Bastion provides secure RDP/SSH access to VMs directly from the Azure portal without requiring public IPs or additional client software.
- B
Azure VPN Gateway
Why wrong: Incorrect. Azure VPN Gateway creates site-to-site or point-to-site VPN connections but still requires the administrator to install a VPN client on their workstation and does not provide browser-based RDP/SSH access.
- C
Azure Firewall
Why wrong: Incorrect. Azure Firewall is a managed network security service that filters network traffic; it does not provide remote desktop or SSH connectivity to VMs.
- D
Azure ExpressRoute
Why wrong: Incorrect. Azure ExpressRoute provides dedicated private network connectivity from on-premises to Azure, but it does not offer browser-based RDP/SSH connectivity and still requires additional configuration and client software for remote access.
AZ-900 Describe Azure architecture and services Practice Question
This AZ-900 practice question tests your understanding of describe azure architecture and services. 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.
A company has deployed several Azure virtual machines in a VNet. The security policy requires that no VM has a public IP address. However, administrators need to connect to the VMs using RDP and SSH for management. The administrators currently use the Azure portal and must not install any additional client software on their local workstations. Which Azure service should they use to meet these requirements?

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
Azure Bastion
Azure Bastion provides secure, seamless RDP and SSH connectivity to Azure VMs directly from the Azure portal over TLS, without exposing any public IP addresses on the VMs. It uses a browser-based HTML5 client, so administrators do not need to install any additional client software on their local workstations, meeting all stated requirements.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
Incorrect. Azure ExpressRoute provides dedicated private network connectivity from on-premises to Azure, but it does not offer browser-based RDP/SSH connectivity and still requires additional configuration and client software for remote access.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure Bastion with Azure VPN Gateway, thinking a VPN provides direct browser-based RDP/SSH without client software, but VPN Gateway requires a VPN client and does not offer portal-based connectivity.
Detailed technical explanation
How to think about this question
Azure Bastion is a PaaS service provisioned inside a VNet that uses a hardened RDP/SSH gateway with TLS 1.2 encryption. It leverages a dedicated subnet called AzureBastionSubnet (minimum /27) and scales out based on connection load. In real-world scenarios, Bastion eliminates the need for jump boxes or public IPs, reducing attack surface while providing audit logging via Azure Monitor.
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
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
