You are developing a ticket reservation system for an airline.
The storage solution for the application must meet the following requirements:
* Ensure at least 99/99% availability and provide low latency.
* Accept reservations even in network outages or other unforseen failures
* Process reservations in the exact sequence as reservation are submitted to minimize overbooking or selling the same seat to multiple travelers.
* Allow simultaneous and out-of-order reservations with a maximum five-second tolerance window.
You provision a resource group named airlineResourceGroup in the Azure South-Central US region.
You need to provision a SQL API Cosmos DB account to support the app.
How should you complete the Azure CLI commands? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

Correct Answer:

Explanation

Box 1: Strong
Strong consistency offers a linearizability guarantee. The reads are guaranteed to return the most recent committed version of an item. A client never sees an uncommitted or partial write. Users are always guaranteed to read the latest committed write.
" Process reservations in the exact sequence as reservation are submitted to minimize overbooking or selling the same seat to multiple travelers." Box 2: Enable-automatic-failover For multi-region Cosmos accounts that are configured with a single-write region, enable automatic-failover by using Azure CLI or Azure portal. After you enable automatic failover, whenever there is a regional disaster, Cosmos DB will automatically failover your account.
