Network security groups contain security rules that enable you to filter the type of
network traffic that can flow in and out of virtual network subnets and network
interfaces. - answer True

A VPN gateway is a type of Virtual Network Gateway. To connect on-premises data
centers to Azure virtual networks you need to configure... - answer site-to-site
connection.
You connect on-premises data centers to Azure virtual networks through a site-to-site
connection.
True or False?
All Azure subscriptions connect from on-premises to Azure using Azure Express Route.
- answer False
Azure ExpressRoute lets you seamlessly extend your on-premises networks into the
Microsoft cloud. This connection between your organization and Azure is dedicated and
private. Establishing an ExpressRoute connection enables you to connect to Microsoft
cloud services like Azure, Office 365, and Dynamics 365. Security is enhanced,
connections are more reliable, latency is minimal, and throughput is greatly increased.
Which of the following resources are required before you can deploy a VPN gateway
between Azure and on-premises resources? - answer 1.) Public IP address.
You must create a Basic-SKU dynamic public IP address if using a non-zone-aware
gateway. This address provides a public-routable IP address as the target for your on-
premises VPN device.
2.) Virtual network.
You must deploy an Azure virtual network with enough address space for the additional
subnet that you'll need for the VPN gateway. The address space for this virtual network
must not overlap with the on-premises network that you'll be connecting to.
3.) Virtual network gateway
