Regions are connected by broadband dedicated lines.

• No
• Sometimes
• Maybe
• Yes

Answer explanation

Overall explanation

The correct answer is "No".

Data centers within a region are connected using a low-latency dedicated regional network. On the other hand, high bandwidth and low latency connections are implemented between regions using VNet peering instead of dedicated lines.

 

Traffic from virtual networks within one region will traverse the MSEE device in the peering location when it leaves the Azure region of origin. That traffic then traverses Microsoft's global network to reach the destination Azure region.

 

More specifically, the following connection methods can be used:

 

- Access over the internet from a public IP address

- Connectivity via Global VNet Peering

- Connection via Private Link

- Connection via VPN

- Connectivity via ExpressRoute Private Peering (implements VPN peering instead of using a dedicated line)

All Azure regions have multiple data centers.

• Yes
• Maybe
• Sometimes
• No

Answer explanation

Overall explanation

The correct answer is "No".

An Azure region is a geographical location where the Azure infrastructure is deployed. A region is set to a country or region. Regions are groups of data centers that are globally distributed around the world in Azure. A region is a geographic area that contains at least one data center, and some regions consist of only one data center.

For regions with Availability Zones, multiple data centers are utilized for redundancy.

Regions corresponding to Availability Zones are made up of multiple data centers. On the other hand, regions that do not support availability zones have a single zone configuration and may use a single data center.　The Osaka region is one example.

Thomas and Lily are discussing Azure. Thomas says that data transfer between storage accounts in the same Azure region is free.

• Yes

• No

• Rarely

• Sometimes

Answer explanation

Overall explanation

The correct answer is "yes".

Since communication within the same region is free, data transfer between storage accounts in the same Azure region is also free. Billing for data transfer in Azure is different for inbound and outbound.

 

Azure communication charge information is as follows:

 

・Communication (inbound) from the Internet or on-premises environment to Azure is free of charge.

・Communication (outbound) from Azure to the Internet or on-premises environment is charged.

・Communication within the same region is free, but some charges will be incurred for communication between availability zones, even within the same region, after July 1, 2023.

Kiara's company has multiple servers in an on-premises environment. They plan to reduce administrative work by migrating these servers to Azure.

 

Which administrative tasks are no longer required after an Azure migration? Please choose two options.

• Permission management for shared documents

• Application data backups

• Server operating system updates

• Replacing failed server hardware

• Physical server security management

Answer explanation

Overall explanation

Options 4 and 5 are correct. On-premises environments have physical servers in data centers, etc., and it is necessary for the company to replace failed server hardware. However, by moving to Azure, the physical hardware is managed in Azure data centers. Therefore, security management of physical servers is performed on the Azure side.

 

Option 1 is incorrect. Access permission management for shared documents assumes management of user operation rules. Such rules should be maintained and managed by the user, and have nothing to do with the cloud. 

Option 2 is incorrect. When an application is built using an Azure virtual machine, the user backs up the application data. 

Option 3 is incorrect. If the user set up an application server on Linux, etc. using an Azure virtual machine, the user will need to update/patch the OS.
