Question : You administer an Azure solution that uses a virtual network named fabVNet. FabVNet has a single subnet named Subnet-1. You discover a high volume of network traffic among four virtual machines (VMs) that are part of Subnet-1. You need to isolate the network traffic among the four VMs. You want to achieve this goal with the least amount of downtime and impact on users. What should you do?
1. Create a new subnet in the existing virtual network and move the four VMs to the new subnet. 2. Create a site-to-site virtual network and move the four VMs to your datacenter. 3. Access Mostly Uused Products by 50000+ Subscribers 4. Create an availability set and associate the four VMs with that availability set.
Explanation:Windows Azure provides routing across subnets within a single virtual network.

Incorrect: not 2: A site-to-site VPN allows you to create a secure connection between your on-premises site and your virtual network. Use a site-to-site connection when: * You want to create a branch office solution. * You want a connection between your on-premises location and your virtual network that's available without requiring additional client-side configurations.
This is basic networking, putting the VMs on their own subnet will isolate the traffic between them. The logic above of ruling it out because traffic is routed between the 4 VMs and other machines does not address what the question asks which was simply isolating traffic between the 4 machines. The question also stipulates "with least amount of downtime and impact on users" which would certainly not be the case creating a new virtual network and connecting it back to the users.
I also searched and don't see that Microsoft has added the ability to move VMs between virtual networks so C is not possible anyways, though it is really tough being tested on technology that is changing constantly you can never be sure they didn't sneak a feature in.
I would say the answer is 1. 4 is obviously not correct, but B and C would require shutting down the machine and migrating it. With option 1 you could configure everything via PowerShell without ever shutting down the machine.
Question : You administer an Azure virtual network named fabrikamVNet. You need to deploy a virtual machine (VM) and ensure that it is a member of the fabrikamVNet virtual network. What should you do?
New-AzureQuickVM Creates and provisions a new Azure virtual machine. because it's a more complete solution. 1 is missing provisioning config.
Question : You manage a large datacenter that has limited physical space. You plan to extend your datacenter to Azure. You need to create a connection that supports a multiprotocol label switching (MPLS) virtual private network. Which connection type should you use?
