Exam AZ-801 topic 5 question 26 discussion

Azure Bastion: This is a managed service that provides secure RDP and SSH connectivity to VMs over a web browser or the Azure portal. However, it requires network connectivity to the VM, as it relies on an established network path to function. Since VM1’s network stack isn’t working, Azure Bastion won’t be able to connect. Serial console: This feature provides direct access to a VM’s serial port through the Azure portal, allowing you to interact with the VM at a low level, similar to a physical machine’s console. It uses the Special Administrative Console (SAC) in Windows Server, which doesn’t depend on the VM’s network stack. This makes it ideal for troubleshooting scenarios like this where network access is unavailable. Just-in-time (JIT) VM access: JIT is a security feature in Azure that temporarily opens network ports (like RDP or SSH) for a specific time window.

As already explained by NazerRazer, right answer is B. Serial console

A and C are wrong because of the following: A. Azure Bastion: Azure Bastion provides secure RDP and SSH connectivity to virtual machines through the Azure portal over SSL. However, it requires the VM to have a functional network stack to establish a connection, which is not the case in this scenario where the network stack fails to initialize. C. Just-in-time (JIT) VM access: JIT VM access is a feature that allows controlled access to VMs by opening up inbound network connectivity for a limited period of time. Similar to Azure Bastion, it relies on the VM having a functional network stack, which is not possible when the network stack fails to initialize. therefore option B is the correct answer the Serial Console provides direct access to the VM's console without relying on a functional network stack, which is essential in this scenario where the network stack fails to initialize.
