Question 1. A company has an on-premises network containing several servers. The company plans to migrate all the servers to Azure. John has been asked to provide a solution to make sure that some of the servers are available in case a single Azure data center goes offline for an extended period. What must John do in this case?
- Fault Tolerance
- Elasticity
- Scalability
- Low Latency
Correct Answer: Fault Tolerance
Explanation: Fault tolerance is the property that allows a system to continue operating properly in the event of the failure of (or one or more faults within) some of its components. The Availability Zones expand the level of control for maintaining the availability of the applications and data on the Virtual Machines. The physical separation of Availability Zones within a region safeguards applications and data from data center failures. Moreover, with Availability Zones, Azure offers an uptime of 99.99% for Virtual Machines SLA. Therefore, by architecting solutions to use replicated Virtual Machines in zones, we can protect the applications and data from the loss of a data center.

Question 10: You have an on-premises network that contains 100 servers. You need to recommend a solution that provides additional resources to your users. The solution must minimize capital and operational expenditure costs. What should you include in the recommendation?
- Complete migration to the public cloud
- Additional data center
- A private cloud
- A hybrid cloud
Correct Answer: Hybrid Cloud
Explanation: A hybrid cloud is a combination of a private cloud and a public cloud. Capital expenditure involves spending money up-front for infrastructure like new servers. Also, with a hybrid cloud, we can use the on-premises servers while adding new servers in the public cloud. Moreover, adding new servers in Azure reduces the capital expenditure costs as we will not be paying for new servers which could have been the case if we deployed new server on-premises.
