Select "Yes" if the following statement is true, otherwise select "No".

 

The ability to dynamically and flexibly change resource allocation is an example of cloud elasticity.

• Yes

• No

Answer explanation

Overall explanation

The correct answer is "yes".

An example of cloud elasticity is the ability to dynamically use cloud resources only as needed in response to system growth. The cloud can flexibly use and stop services dynamically based on the needs. And you will be charged according to the time you actually use. This is called cloud elasticity.

The ability to continue providing your service even when a failure occurs is an example of cloud elasticity.

• Yes

• No

Answer explanation

Overall explanation

The correct answer is "No".

The ability to continue service in the event of a failure is an example of cloud resilience. For example, every Azure region that supports availability zones has at least three separate zones to ensure resilience. This makes it possible to make services redundant and facilitate recovery in the event of a failure.

Being able to maintain DR (Disaster Recovery) configurations in other regions is an example of cloud elasticity.

• Yes

• No

Answer explanation

Overall explanation

The correct answer is "No".

Being able to maintain DR (Disaster Recovery) configurations in other regions is an example of cloud resiliency. For example, with Azure, you can use Azure Site Recovery to continuously replicate virtual machines and physical servers at an on-premises primary site, and in the event of a failure, you can quickly recover from a failure by replicating the servers at a secondary site.

Your company launches 10 Windows Server 2016 servers and 20 Linux virtual machines of a specific instance size to test the application. It is necessary to delete these virtual machines after the test is finished.

Which Azure service should be used to minimize the administrative effort required to deploy and remove these virtual machines?

• Microsoft Virtual Desktop

• Azure Reserved VM Instances

• Azure DevTest Labs

• Azure virtual machine scale set

Answer explanation

Overall explanation

Option 3 will be the correct answer. Azure DevTest Labs can build fast and lean dev/test environments. You can deploy as many virtual machines as you need by using an Azure Resource Manager template that pre-configures the number of virtual machines and settings. This makes it possible to create a template for the instance execution environment, such as a test environment, and allows you to repeat the act of starting and deleting it.

 

Option 1 is incorrect. Microsoft Virtual Desktop is a desktop and app virtualization service that runs on the cloud.

Option 2 is incorrect. Azure Reserved VM Instances is a service for reserving instances and getting discounted pricing. You can use a virtual machine of a size within a reserved instance size group at a discounted price.

Option 4 is incorrect. Azure Virtual Machine Scale Sets is a feature that allows you to create and manage groups of virtual machines and load balance them within the same group. It is used when building large-scale services.

If the resource group named MyResourceGroup has a delete lock, _____________________

• Only members of the global administrator group can delete MyResourceGroup

• In order for the administrator to delete MyResourceGroup, the deletion lock must be released

• In order for the administrator to delete MyResourceGroup, the Azure policy must be released

• In order for the administrator to delete MyResourceGroup, the Azure tags must be added

Answer explanation

Overall explanation

Option 2 is the correct answer. When you apply a delete lock on a resource group, the lock applies to all resources within that group. Therefore, if an administrator wants to delete the target resource, the deletion lock must be released. Even an administrator cannot delete a resource group if a lock is applied to the resource group. However, administrators do have the authority to remove delete locks on resource groups.

 

Option 1 is incorrect. Even global administrators cannot delete it as long as the resource group's delete lock is in effect.

Option 3 is incorrect. Azure Policy is a feature used to enforce compliance and organizational rules on resources and has nothing to do with deletion locks.

Option 4 is incorrect. Tags are used for the logical grouping of resources and are not related to delete locks.

In order to move to a hybrid cloud, you must move away from a private cloud.

• Yes

• No

Answer explanation

Overall explanation

The correct answer is "No".

To achieve a hybrid cloud model, it is possible to migrate from either a public cloud model or a private cloud model. You can choose the migration method according to your company's needs and current cloud model usage. There are three main configurations of hybrid cloud.

 

・Hybrid cloud configuration combining public cloud and private cloud

・Hybrid cloud configuration combining on-premises and public cloud

・Hybrid cloud configuration combining multiple public clouds such as Azure and AWS
