Exam AZ-700 topic 1 question 7 discussion

Answer: A - 1 Managing Authorization The circuit owner can share a circuit with up to 10 Azure subscriptions. The circuit owner can view who has been authorized to the circuit. The owner can revoke the authorization at any time. https://azure.microsoft.com/en-us/blog/enable-multiple-subscription-expressroute/#:~:text=The%20circuit%20owner%20can%20share,the%20authorization%20at%20any%20time.

1 Express Route Circuit standard sku would be good enough. With 1 er circuit you can connect upto 10 vnets and standard sku allows you to connect within same geopolitical region without additional cost.

Correct answer.

A One ER Required.

people saying A-1 is correct have 0 knowledge of how Networking Infrastructure works. You need 2: Since all resources in the subscriptions are in either the West US or the West US 2 regions, and you plan to connect all the subscriptions to the on-premises network, you only need one circuit per region. Therefore, a total of two ExpressRoute circuits are required, one for West US and one for West US 2.

Not true for Local SKU though. . With a Local SKU ExpressRoute circuit you can connect to resources in Azure regions in the same metro as the peering site. In this case, your on-premises network can access UK South Azure resources over ExpressRoute. For more information, see What is ExpressRoute Local?. When you configure a Standard SKU ExpressRoute circuit, connectivity to Azure resources will expand to all Azure regions in a geopolitical area. https://learn.microsoft.com/en-us/azure/expressroute/expressroute-faqs

You can link up to 10 virtual networks to a standard ExpressRoute circuit. All virtual networks must be in the same geopolitical region when using a standard ExpressRoute circuit. West US and West US 2 are in the same Azure geopolitical region, so you would need only one ER circuits. https://learn.microsoft.com/en-us/azure/expressroute/expressroute-howto-linkvnet-portal-resource-manager#connect-a-vnet-to-a-circuit---different-subscription https://learn.microsoft.com/en-us/azure/expressroute/expressroute-locations-providers

Answer A is correct. As already mentioned by others you can connect 10 Virtual Networks to a single ExpressRoute Circuit (Standard SKU or higher required). What is important to understand is that those Virtual Networks (e.g., Virtual Network Gateways) must be in the same geographical region. Well, 'West US' and 'West US 2' are in the same geographical region.

https://learn.microsoft.com/en-us/azure/expressroute/expressroute-faqs Yes. You can link up to 10 virtual networks in the same subscription as the circuit or different subscriptions using a single ExpressRoute circuit. This limit can be increased by enabling the ExpressRoute premium feature. Connectivity and bandwidth charges for the dedicated circuit gets applied to the ExpressRoute circuit owner and all virtual networks share the same bandwidth.

1 Express Route Circuit standard sku would be good enough. With 1 er circuit you can connect upto 10 vnets and standard sku allows you to connect within same geopolitical region without additional cost.

Answer: A - 1

if the express route would be with a standard SKU, then yes, I think A - 1 express route would be enough

B. 2 You need at least two ExpressRoute circuits to connect all three Azure subscriptions to the on-premises network. One circuit connects the West US Azure region and another circuit connects the West US 2 Azure region. All the resources in the subscriptions are in either the West US Azure region or the West US 2 Azure region, so you need to connect both regions.

1 Express Route Circuit standard sku would be good enough. With 1 er circuit you can connect upto 10 vnets and standard sku allows you to connect within same geopolitical region without additional cost.

Answer: A - 1

ExpressRoute circuits can be shared between subscriptions. Correct answer is A

Looks like the correct answer is A You can have an ExpressRoute Circuit going into one region and gain access to other regions from there... Connectivity to all regions within a geopolitical region You can connect to Microsoft in one of our peering locations and access regions within the geopolitical region. For example, if you connect to Microsoft in Amsterdam through ExpressRoute. You'll have access to all Microsoft cloud services hosted in Northern and Western Europe. For an overview of the geopolitical regions, the associated Microsoft cloud regions, and corresponding ExpressRoute peering locations, see the ExpressRoute partners and peering locations article. https://docs.microsoft.com/en-us/azure/expressroute/expressroute-introduction#connectivity-to-all-regions-within-a-geopolitical-region
