A company has deployed several Azure VMs that do not have public IP addresses. Administrators need to securely connect to these VMs using RDP and SSH from the internet over a browser without deploying a jump box or managing VPN connections. The solution must use Microsoft Entra ID authentication for single sign-on. Which Azure service should they use?
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 Jump Box VM
A jump box VM would require a public IP and additional security management, and it does not natively integrate with Microsoft Entra ID for single sign-on.
B
Best answer
Azure Bastion
Azure Bastion offers secure, browser-based RDP/SSH connections to VMs without public IPs, supports Microsoft Entra ID authentication, and is fully managed.
C
Distractor review
Azure VPN Gateway
VPN Gateway provides site-to-site or point-to-site connectivity but requires client software and does not offer browser-based direct VM access.
D
Distractor review
Azure ExpressRoute
ExpressRoute is a dedicated private connection between on-premises and Azure, not designed for remote individual access to VMs.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this AZ-305 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Azure Bastion — Azure Bastion provides secure and seamless RDP/SSH connectivity to VMs directly from the Azure portal over TLS, without exposing public IPs. It supports Microsoft Entra ID authentication and eliminates the need for a jump box or VPN. A jump box VM would require management and public IP exposure. VPN Gateway adds complexity and does not provide browser-based access. ExpressRoute is a private connection between on-premises and Azure, not for remote access to VMs.
