Exam AZ-104 topic 5 question 69 discussion

Actual exam question from Microsoft's AZ-104
Question #: 69
Topic #: 5
[All AZ-104 Questions]

You have an Azure subscription that contains a policy-based virtual network gateway named GW1 and a virtual network named VNet1.
You need to ensure that you can configure a point-to-site connection from an on-premises computer to VNet1.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.

  • A. Add a service endpoint to VNet1
  • B. Reset GW1
  • C. Create a route-based virtual network gateway
  • D. Add a connection to GW1
  • E. Delete GW1
  • F. Add a public IP address space to VNet1
Show Suggested Answer Hide Answer
Suggested Answer: CE 🗳️
C: A VPN gateway is used when creating a VPN connection to your on-premises network.
Route-based VPN devices use any-to-any (wildcard) traffic selectors, and let routing/forwarding tables direct traffic to different IPsec tunnels. It is typically built on router platforms where each IPsec tunnel is modeled as a network interface or VTI (virtual tunnel interface).
E: Policy-based VPN devices use the combinations of prefixes from both networks to define how traffic is encrypted/decrypted through IPsec tunnels. It is typically built on firewall devices that perform packet filtering. IPsec tunnel encryption and decryption are added to the packet filtering and processing engine.
Incorrect Answers:
F: Point-to-Site connections do not require a VPN device or a public-facing IP address.

Answer is E & C When you create the virtual network gateway for a VPN gateway configuration, you must specify a VPN type. The VPN type that you choose depends on the connection topology that you want to create. For example, a P2S connection requires a RouteBased VPN type. https://learn.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-about-vpn-gateway-settings. If you want to use a PolicyBased VPN type, you must use the Basic SKU. PolicyBased VPNs (previously called Static Routing) are not supported on any other SKU. PolicyBased Basic VPN Gateway does not support Point-to-Site connectivity. https://learn.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-about-skus-legacy.

Answer is C and E ( Order does not matter as this is not drag and drop question) The policy type VNG does not support Point to Site VPN . You cant have 2 VNG in the same VNET . So the existing policy-based VNG must be deleted so you can create a route based VPN

Policy-based virtual network gateways are typically used with certain firewall devices and support a specific type of VPN configuration. They do not support point-to-site connections. Wouldnt we need a point-to-site connection from an on-premises computer to VNet1, and so we will need to use a route-based virtual network gateway instead. So C and D

OpenAI "To configure a point-to-site connection from an on-premises computer to VNet1, you need to perform the following two actions: D. Add a connection to GW1: You need to add a point-to-site connection to GW1. This will allow the on-premises computer to connect to VNet1 via GW1. C. Create a route-based virtual network gateway: You need to create a route-based virtual network gateway to ensure that the point-to-site connection can be established from the on-premises computer to VNet1. Therefore, the correct answers are D and C. The other options are not required for setting up a point-to-site connection from an on-premises computer to VNet1. A. Adding a service endpoint to VNet1 is used for enabling the traffic from the subnet to use the service provided by Azure services privately. B. Resetting GW1 is not required for this task. E. Deleting GW1 would remove the virtual network gateway, which is not required. F. Adding a public IP address space to VNet1 would not be required for a point-to-site connection."

Yep Delete Existing GW and create New route-based GW When you create the virtual network gateway for a VPN gateway configuration, you must specify a VPN type. The VPN type that you choose depends on the connection topology that you want to create. For example, a P2S connection requires a RouteBased VPN type. A VPN type can also depend on the hardware that you're using. S2S configurations require a VPN device. Some VPN devices only support a certain VPN type PolicyBased VPNs can only be used on the Basic gateway SKU. This VPN type is not compatible with other gateway SKUs.

You can have only 1 tunnel when using a PolicyBased VPN. You can only use PolicyBased VPNs for S2S connections, and only for certain configurations. Most VPN Gateway configurations require a RouteBased VPN. RouteBased: RouteBased VPNs were previously called dynamic routing gateways in the classic deployment model. RouteBased VPNs use "routes" in the IP forwarding or routing table to direct packets into their corresponding tunnel interfaces. The tunnel interfaces then encrypt or decrypt the packets in and out of the tunnels. The policy (or traffic selector) for RouteBased VPNs are configured as any-to-any (or wild cards). The value for a RouteBased VPN type is RouteBased.
