Question 1 :

You have an on-premises network that contains several servers.

You plan to migrate all the servers to Azure.

You need to recommend a solution to ensure that some of the servers are available if a single Azure data center goes offline for an extended period.

What should you include in the recommendation?

Options:

A. fault tolerance

B. elasticity

C. scalability

D. low latency 


Answer:  A


Explanation:

ce is the ability of a system to continue to function in the event of a failure of some of its components.

In this question, you could have servers that are replicated across datacenters.

Availability zones expand the level of control you have to maintain the availability of the applications and data on your VMs. Availability Zones are unique physical locations within an Azure region. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking. To ensure resiliency, there are a minimum of three separate zones in all enabled regions.

The physical separation of Availability Zones within a region protects applications and data from data center failures. With Availability Zones, Azure offers industry best 99.99% VM uptime SLA. By architecting your solutions to use replicated VMs in zones, you can protect your applications and data from the loss of a data center. If one zone is compromised, then replicated apps and data are instantly available in another zone.



Question 2 :

This question requires that you evaluate the underlined text to determine if it is correct.

An organization that hosts its infrastructure in a private cloud can decommission its data center.

Instructions: Review the underlined text. If it makes the statement correct, select “No change is needed”. If the statement is incorrect, select the answer choice that makes the statement correct.

Options:

A. No change is needed.

B. in a hybrid cloud

C. in the public cloud

D. on a Hyper-V host


Answer: C


Explanation:

ud is hosted in your data center. Therefore, you cannot close your data center if you are

using a private cloud. A public cloud is hosted externally, for example, in Microsoft Azure. An organization that hosts its infrastructure in a public cloud can close its data center.Public cloud is the most common deployment model. In this case, you have no local hardware to manage or keep up-to-date everything runs on your cloud provider's hardware



Question 3 :

What are two characteristics of the public cloud? Each correct answer presents a complete solution.

NOTE: Each correct selection is worth one point.

Options:

A. dedicated hardware

B. unsecured connections

C. limited storage

D. metered pricing

E. self-service management


Answer: D, E

Explanation:

ic cloud, you get pay-as-you-go pricing – you pay only for what you use, no CapEx costs.

With the public cloud, you have self-service management. You are responsible for the deployment and configuration of the cloud resources such as virtual machines or web sites. The underlying hardware that hosts the cloud resources is managed by the cloud provider.



Question 4 :

This question requires that you evaluate the underlined text to determine if it is correct.

When planning to migrate a public website to Azure, you must plan to pay monthly usage costs.

Instructions: Review the underlined text. If it makes the statement correct, select “No change is

needed”. If the statement is incorrect, select the answer choice that makes the statement correct.


Options:

A. No change is needed

B. Deploy a VPN

C. pay to transfer all the website data to Azure

D. reduce the number of connections to the website


Answer: A
