Question
Note: The question is included in a number of questions that depicts the identical set-up. However, every question has a distinctive result. Establish if the solution satisfies the requirements.
You are tasked with deploying a critical LOB application, which will be installed on a virtual machine, to Azure.
You are informed that the application deployment strategy should allow for a guaranteed availability of 99.99 percent. You need to make sure that the strategy requires as little virtual machines and availability zones as possible.
Solution: You include two virtual machines and one availability zone in your strategy.
Does the solution meet the goal?
- A. Yes
- B. No Correct
Explanation
The solution does not meet the goal. The Azure virtual machine SLA guarantees 99.99% connectivity only when two or more VM instances are deployed across two or more Availability Zones in the same region. Placing both virtual machines in a single Availability Zone does not qualify for that SLA, because one zone outage would take both VMs down. The minimum that meets 99.99% is two virtual machines spread across two Availability Zones.
