Which of the following are examples of NVAs in Azure? (Select all that apply)

The correct answer includes Network Virtual Appliance as it represents a dedicated virtual appliance designed for network functions such as routing, firewall capabilities, or VPN services. NVAs are typically deployed as specialized virtual machines that can be configured to manage and optimize network traffic, offering features that go beyond standard networking capabilities provided by Azure itself. They can be used for security, monitoring, and various other advanced network processing tasks.

While third-party devices in the Azure marketplace can offer a range of services, not every device qualifies as an NVA. Some may serve other purposes, such as application-specific functions, without fitting the networking appliance category. Similarly, although Virtual Network Gateway and ExpressRoute Gateway are critical components for connecting Azure networks and facilitating secure connections between on-premises networks and Azure, they are not classified as NVAs. Instead, they are built-in services provided by Azure for connection management rather than standalone virtual appliances.

This contextual understanding underlines why identifying NVAs is focused specifically on dedicated network appliance functionalities, which reinforces the distinction of Network Virtual Appliance as the correct answer.
