HOTSPOT (Drag and Drop is not supported)
You need to recommend a solution for App1. The solution must meet the technical requirements.
What should you include in the recommendation? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.
Hot Area:

  1. See Explanation section for answer.

Answer(s): A

Explanation:




This reference architecture shows how to deploy VMs and a virtual network configured for an N-tier application, using SQL Server on Windows for the data tier.


Scenario: You have a public-facing application named App1. App1 is comprised of the following three tiers:

-A SQL database
-A web front end
-A processing middle tier

Each tier is comprised of five virtual machines. Users access the web front end by using HTTPS only. Technical requirements include:
-Move all the virtual machines for App1 to Azure.
-Minimize the number of open ports between the App1 tiers.

You are planning the move of App1 to Azure. You create a network security group (NSG).
You need to recommend a solution to provide users with access to App1. What should you recommend?

  1. Create an incoming security rule for port 443 from the Internet. Associate the NSG to the subnet that contains the web servers.
  2. Create an outgoing security rule for port 443 from the Internet. Associate the NSG to the subnet that contains the web servers.
  3. Create an incoming security rule for port 443 from the Internet. Associate the NSG to all the subnets.
  4. Create an outgoing security rule for port 443 from the Internet. Associate the NSG to all the subnets.

Answer(s): A

Explanation:

Incoming and the web server subnet only, as users access the web front end by using HTTPS only.

Note Scenario: You have a public-facing application named App1. App1 is comprised of the following three tiers:
-A SQL database
-A web front end
-A processing middle tier

Each tier is comprised of five virtual machines. Users access the web front end by using HTTPS only.

You need to ensure that VM1 can communicate with VM4. The solution must minimize the administrative effort.

What should you do?

  1. Create an NSG and associate the NSG to VM1 and VM4.
  2. Establish peering between VNET1 and VNET3.
  3. Assign VM4 an IP address of 10.0.1.5/24.
  4. Create a user-defined route from VNET1 to VNET3.

HOTSPOT (Drag and Drop is not supported)
You need to meet the connection requirements for the New York office.
What should you do? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Hot Area:

  1. See Explanation section for answer.

Answer(s): A

Explanation:



Box 1: Create a virtual network gateway and a local network gateway.
Azure VPN gateway. The VPN gateway service enables you to connect the VNet to the on-premises network through a VPN appliance. For more information, see Connect an on-premises network to a Microsoft Azure virtual network. The VPN gateway includes the following elements:
Virtual network gateway.A resource that provides a virtual VPN appliance for the VNet. It is responsible for routing traffic from the on-premises network to the VNet.
Local network gateway.An abstraction of the on-premises VPN appliance. Network traffic from the cloudapplication to the on-premises network is routed through this gateway.
Connection. The connection has properties that specify the connection type (IPSec) and the key shared with the on-premises VPN appliance to encrypt traffic.
Gateway subnet. The virtual network gateway is held in its own subnet, which is subject to various requirements, described in the Recommendations section below.

Box 2: Configure a site-to-site VPN connection
On premises create a site-to-site connection for the virtual network gateway and the local network gateway.


Scenario: Connect the New York office to VNet1 over the Internet by using an encrypted connection. Incorrect Answers:
Azure ExpressRoute: Established between your network and Azure, through an ExpressRoute partner. This connection is private. Traffic does not go over the internet.
