How does Azure Bastion improve VM access security?

Azure Bastion allows you to connect to your virtual machines (VMs) securely. What is the main way it improves security compared to traditional methods?

A It uses VPN tunnels to connect to VMs through a private network.

B It provides direct RDP/SSH access over the internet without exposing VM public IPs.

C It disables all network traffic except from a specific IP address range.

D It requires installing extra software agents on the VM to encrypt traffic.

💡 Hint

Think about how Azure Bastion avoids exposing your VM directly to the internet.

Azure Bastion provides secure RDP/SSH connectivity directly in the Azure portal without exposing the VM's public IP address, reducing attack surface.

❓ Configuration

intermediate

Which Azure Bastion configuration is required to enable secure VM access?

You want to set up Azure Bastion to securely connect to VMs in a virtual network. Which configuration step is mandatory?

A Create an Azure Bastion resource in the same virtual network as the VMs.

B Assign a public IP address to each VM you want to access.

C Enable Azure Bastion in a different subscription than the VMs.

D Install the Azure Bastion agent on each VM.

💡 Hint

Consider where the Bastion service must be deployed relative to the VMs.

Azure Bastion must be deployed in the same virtual network as the VMs to provide secure RDP/SSH access without exposing public IPs.

❓ Architecture

advanced

What is the correct network architecture to use Azure Bastion for multiple subnets?

You have VMs in multiple subnets within a virtual network. How should you architect Azure Bastion to allow secure access to all VMs?

A Deploy a single Azure Bastion in the virtual network; it can access all subnets automatically.

B Deploy one Azure Bastion per subnet to cover all VMs.

C Deploy Azure Bastion in a separate virtual network and peer it with the VM network.

D Assign public IPs to VMs in other subnets to access them via Bastion.

💡 Hint

Think about how Azure Bastion integrates with virtual networks and subnets.

Azure Bastion deployed in a virtual network provides secure access to all VMs in all subnets within that network without needing multiple Bastion instances.

❓ security

advanced

Which security feature does Azure Bastion NOT provide by default?

Azure Bastion enhances VM access security. Which of the following is NOT a security feature provided by Azure Bastion?

A Protection against port scanning and brute force attacks on VMs.

B End-to-end encryption of RDP/SSH sessions via TLS.

C Multi-factor authentication enforcement for VM login.

D No need to expose public IP addresses on VMs.

💡 Hint

Consider which security controls are handled by Azure Bastion versus Azure Active Directory or other services.

Azure Bastion provides secure connectivity and protects against network attacks but does not enforce multi-factor authentication; that is managed separately.

✅ Best Practice

expert

What is the best practice for scaling Azure Bastion in a large enterprise environment?

Your organization has multiple virtual networks across regions and needs secure VM access via Azure Bastion. What is the best practice for scaling Azure Bastion?

A Assign public IPs to all VMs and disable Azure Bastion to simplify access.

B Deploy a single Azure Bastion in one region and peer all virtual networks to it for centralized access.

C Use a VPN gateway instead of Azure Bastion to reduce the number of Bastion deployments.

D Deploy Azure Bastion in each virtual network where VMs reside to minimize latency and maximize security.

💡 Hint

Think about network latency, security boundaries, and Azure Bastion's deployment scope.

Azure Bastion is deployed per virtual network. For multiple networks, deploy Bastion in each to ensure secure, low-latency access without exposing VMs.
