Q

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?

A

Read-only geo-redundant storage

RA-GRS allows you to have higher read availability for your storage account by providing ג€read onlyג€ 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
ג€opt-inג€ feature which requires the storage account be geo-replicated.

Q

Your company is planning to migrate all their virtual machines to an Azure pay-as-you-go subscription. The virtual machines are currently hosted on the Hyper-V hosts in a data center.
You are required make sure that the intended Azure solution uses the correct expenditure model.
Solution: You should recommend the use of the elastic expenditure model.
Does the solution meet the goal?

A

No,

Elasticity is not an expenditure model rather is one of the characteristics of could computing. The basic advantage of cloud computing is shifting your high Capital Expenditure (CAPEX) requirements to optimal Pay -As-You-Go model which is Operational Expenditure (OPEX)

33
Q

PaaS Solution that hosts web apps in Azure provides full control of the operating systems that host applications Y/N?

A

No,

A PaaS solution does not provide access to the operating system. The Azure Web Apps service provides an environment for you to host your web applications.
Behind the scenes, the web apps are hosted on virtual machines running IIS. However, you have no direct access to the virtual machine, the operating system or
IIS.

34
Q

PaaS solution that hosts web apps in Azure provides the ability to scale the platform automatically? (Y/N)?

A

Yes,

A PaaS solution that hosts web apps in Azure does provide the ability to scale the platform automatically. This is known as autoscaling. Behind the scenes, the web apps are hosted on virtual machines running IIS. Autoscaling means adding more load balanced virtual machines to host the web apps.

35
Q

PaaS solution that hosts web apps in Azure provides professional development services to continuously add features to custom applications. (Y/N)?

A

Yes,

PaaS provides a framework that developers can build upon to develop or customize cloud-based applications. PaaS development tools can cut the time it takes to code new apps with pre-coded application components built into the platform, such as workflow, directory services, security features, search and so on.

36
Q

Azure provides flexibility between capital expenditure (CapEx) and Operational expenditure (OpEx). (Y/N)?

A

Yes,

Traditionally, IT expenses have been considered a Capital Expenditure (CapEx). Today, with the move to the cloud and the pay-as-you-go model, organizations have the ability to stretch their budgets and are shifting their IT CapEx costs to Operating Expenditures (OpEx) instead. This flexibility, in accounting terms, is now an option due to the ג€as a Serviceג€ model of purchasing software, cloud storage and other IT related resources.

37
Q

If you create two Azure virtual machines that use B2S size, each virtual machine will always generate the same monthly costs.

A

No,

Two virtual machines using the same size could have different disk configurations. Therefore, the monthly costs could be different.

38
Q

When an Azure virtual machine is stopped, you continue to pay storage costs associated to the virtual machine.

A

Yes,

When an Azure virtual machine is stopped, you don’t pay for the virtual machine. However, you do still pay for the storage costs associated to the virtual machine.
The most common storage costs are for the disks attached to the virtual machines. There are also other storage costs associated with a virtual machine such as storage for diagnostic data and virtual machine backups.

39
Q

When you are implementing a Software as a Service (SaaS) solution, you are responsible for

A. configuring high availability
B. defining scalability rules.
C. installing the SaaS Solution.
D. Configuring the SaaS solution.

A

Configuring the SaaS Solution.

When you are implementing a Software as a Service (SaaS) solution, you are responsible for configuring the SaaS solution. Everything else is managed by the cloud provider.
SaaS requires the least amount of management. The cloud provider is responsible for managing everything, and the end user just uses the software.
Software as a service (SaaS) allows users to connect to and use cloud-based apps over the Internet. Common examples are email, calendaring and office tools

40
Q
