1. Your developers have created a portal web app for users in the Miami branch office. The web app will be publicly accessible and used by the Miami users to retrieve customer and product information. The web app is currently running in an on-premises test environment. You plan to host the web app on Azure. You need to determine which Azure web tier plan to host the web app. The web tier plan must meet the following requirements: The website will use the miami.weyland.com URL. The website will be deployed to two instances. SSL support must be included. The website requires 12 GB of storage. Costs must be minimized. Which web tier plan should you use?

2. Your developers have created 10 web applications that must be host on Azure. You need to determine which Azure web tier plan to host the web apps. The web tier plan must meet the following requirements: The web apps will use custom domains. The web apps each require 10 GB of storage. The web apps must each run in dedicated compute instances. Load balancing between instances must be included. Costs must be minimized. Which web tier plan should you use?
Explanation: Standard offers 50 GB of storage space, while Basic only gives 10 GB. References: http://azure.microsoft.com/en-us/pricing/details/websites/

4. You have an on-premises network that contains several servers.You plan to migrate all the servers to Azure. You need to recommend a solution to ensure that some of the servers are available if a single Azure data center goes offline for an extended period. What should you include in the recommendation?
Explanation: Fault tolerance is the ability of a system to continue to function in the event of a failure of some of its components. In this question, you could have servers that are replicated across datacenters. Availability zones expand the level of control you have to maintain the availability of the applications and data on your VMs. Availability Zones are unique physical locations within an Azure region. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking. To ensure resiliency, there are a minimum of three separate zones in all enabled regions. The physical separation of Availability Zones within a region protects applications and data from datacenter failures. With Availability Zones, Azure offers industry best 99.99% VM uptime SL By architecting your solutions to use replicated VMs in zones, you can protect your applications and data from the loss of a datacenter. If one zone is compromised, then replicated apps and data are instantly available in another zone. References: https://docs.microsoft.com/en-us/azure/virtual-machines/windows/manage-availability

5. Your company has datacenters in Los Angeles and New York. The company has a Microsoft Azure subscription. You are configuring the two datacenters as geo-clustered sites for site resiliency. You need to recommend an Azure storage redundancy option. You have the following data storage requirements: Data must be stored on multiple nodes. Data must be stored on nodes in separate geographic locations. Data can be read from the secondary location as well as from the primary location Which of the following Azure stored redundancy options should you recommend?
Explanation: RA-GRS allows you to have higher read availability for your storage account by providing “read only” access to the data replicated to the secondary location. Once you enable this feature, the secondary location may be used to achieve higher availability in the event the data is not available in the primary region. This is an “opt-in” feature which requires the storage account be geo-replicated. References: https://docs.microsoft.com/en-us/azure/storage/common/storage-redundancy
