AZ-304 – Question #105


Question #105

You have an on-premises network to which you deploy a virtual appliance.
You plan to deploy several Azure virtual machines and connect the on-premises network to Azure by using a Site-to-Site connection.
All network traffic that will be directed from the Azure virtual machines to a specific subnet must flow through the virtual appliance.
You need to recommend solutions to manage network traffic.
Which two options should you recommend? Each correct answer presents a complete solution.

A. Configure Azure Traffic Manager.
B. Implement Azure ExpressRoute.
C. Configure a routing table.

D. Implement an Azure virtual network.

Correct Answer: BC
B: Forced tunneling lets you redirect or “force” all Internet-bound traffic back to your on-premises location via a Site-to-Site VPN tunnel for inspection and auditing.
This is a critical security requirement for most enterprise IT policies. Without forced tunneling, Internet-bound traffic from your VMs in Azure always traverses from
Azure network infrastructure directly out to the Internet, without the option to allow you to inspect or audit the traffic.
Forced tunneling in Azure is configured via virtual network user-defined routes.
C: ExpressRoute lets you extend your on-premises networks into the Microsoft cloud over a private connection facilitated by a connectivity provider. With
ExpressRoute, you can establish connections to Microsoft cloud services, such as Microsoft Azure, Office 365, and Dynamics 365.
Connectivity can be from an any-to-any (IP VPN) network, a point-to-point Ethernet network, or a virtual cross-connection through a connectivity provider at a co- location facility. ExpressRoute connections do not go over the public Internet. This allows ExpressRoute connections to offer more reliability, faster speeds, lower latencies, and higher security than typical connections over the Internet.
