Question 581
You plan to implement an Azure database solution.
You need to implement a database solution that meets the following requirements:
- Can add data concurrently from multiple regions
- Can store JSON documents
Which database service should you deploy?
To answer, select the appropriate service in the answer area.
*A. Azure Cosmos DB
B. Azure Database for MySQL servers
C. Azure Database for MariaDB servers
D. SQL Data warehouses
E. Azure Cache for Redis
F. Data factories
G. Virtual Clusters
H. Elastic Job agents
I. SQL databases
J. Azure Database for PostgreSQL servers
K. SQL servers
L. Azure Database Migration Services
M. SQL Server stretch databases
N. SQL elastic pools
O. Managed databases
P. SQL managed instances
Explanation
Azure Cosmos DB is Microsoft’s globally distributed, multi-model database service. With a click of a button, Cosmos DB enables you to elastically and independently scale throughput and storage across any number of Azure regions worldwide.
Azure Cosmos DB is a great way to store unstructured and JSON data. Combined with Azure Functions, Cosmos DB makes storing data quick and easy with much less code than required for storing data in a relational database.
Question 582
All the Azure resources deployed to a resource group must use the same Azure region.
A. Yes
*B. No
Explanation
Azure resources deployed to a single resource group can be located in different regions. The resource group only contains metadata about the resources it contains.
When creating a resource group, you need to provide a location for that resource group. You may be wondering, “Why does a resource group need a location?
And, if the resources can have different locations than the resource group, why does the resource group location matter at all?” The resource group stores metadata about the resources. When you specify a location for the resource group, you’re specifying where that metadata is stored. For compliance reasons, you may need to ensure that your data is stored in a particular region.
Question 583
If you assign a tag to a resource group, all the Azure resources in that resource group are assigned to the same tag.
A. Yes
*B. No
Explanation
Tags for Resources are not inherited by default from their Resource Group
Question 584
If you assign permissions for a user to manage a resource group, the user can manage all the Azure resources in that resource group.
*A. Yes
B. No
Explanation
A resource group can be used to scope access control for administrative actions. By default, permissions set at the resource level are inherited by the resources in the resource group.
Question 585
Data that is stored in an Azure Storage account automatically has at least three copies.
*A. Yes
B. No
Explanation
There are different replication options available with a storage account. The ‘minimum’ replication option is Locally Redundant Storage (LRS). With LRS, data is replicated synchronously three times within the primary region.
Question 586
All data that is copied to an Azure Storage account is backed up automatically to another Azure data center.
A. Yes
*B. No
Explanation
Data is not backed up automatically to another Azure Data Center although it can be depending on the replication option configured for the account. Locally
Redundant Storage (LRS) is the default which maintains three copies of the data in the data center.
Geo-redundant storage (GRS) has cross-regional replication to protect against regional outages. Data is replicated synchronously three times in the primary region, then replicated asynchronously to the secondary region.
Question 587
An Azure Storage account can contain up to 2 TB of data and up to one million files.
A. Yes
*B. No
Explanation
The limits are much higher than that. The current storage limit is 2 PB for US and Europe, and 500 TB for all other regions (including the UK) with no limit on the number of files.
Question 588
You need to be notified when Microsoft plans to perform maintenance that can affect the resources deployed to an Azure subscription.
What should you use?
A. Azure Monitor
*B. Azure Service Health
C. Azure Advisor
D. Microsoft Trust Center
Explanation
Azure Service Health provides a personalized view of the health of the Azure services and regions you’re using. This is the best place to look for service impacting communications about outages, planned maintenance activities, and other health advisories because the authenticated Service Health experience knows which services and resources you currently use.
Question 589
Match the Azure Services service to the correct description.
Instructions: To answer, drag the appropriate service from the column on the left to its description on the right. Each service may be used once, more than once, or not at all.
NOTE: Each correct selection is worth one point.
