Which statement best describes a Hybrid Cloud architecture?
- Does not require any on-premise hardware
- Utilizes services of both Public and Private Clouds
- Cannot be used with Microsoft Azure
- Special use case for secure Government workloads
-Utilizes services of both Public and Private Clouds
A Hybrid Cloud architecture describes a solution that utilizes both Public and Private Cloud offerings, including private on-premise systems. This is useful, because it allows companies the flexibility of the cloud, but can also manage tight governance requirements which may not allow certain data to be held in the Public Cloud. This can require on-premise hardware. This approach is possible with Microsoft Azure, and is not specific to any type of workloads, although Governments may find this especially useful.

What is the description of a region in Microsoft Azure?
- A geographical area containing at least one Azure datacenter per continent worldwide.
- A geographical area containing all of the Azure datacenters located within a single countries borders.
- A logical boundary defining the secure communication boundary between a customers virtual machines.
- A set of datacenters deployed within a latency-defined perimeter and connected through a dedicated regional low-latency network.
-A set of datacenters deployed within a latency-defined perimeter and connected through a dedicated regional low-latency network.
An Azure region is a set of data centres, deployed within a latency-defined perimeter and connected through a dedicated regional low-latency network. With more global regions than any other cloud service provider, Azure gives customers the flexibility to deploy applications where they need. An Azure region has discrete pricing and service availability.
Which of the following are available in the Azure Marketplace?
(choose 3)
- Solution templates
