Correct Answer: C
Section: Understand Core Azure Services
Explanation
Explanation/Reference:

Explanation:
Azure Files is Microsoft’s easy-to-use cloud file system. Azure file shares can be seamlessly used in Windows
and Windows Server.
To use an Azure file share with Windows, you must either mount it, which means assigning it a drive letter or
mount point path, or access it via its UNC path.
Unlike other SMB shares you may have interacted with, such as those hosted on a Windows Server, Linux
Samba server, or NAS device, Azure file shares do not currently support Kerberos authentication with your
Active Directory (AD) or Azure Active Directory (AAD) identity, although this is a feature we are working on.
Instead, you must access your Azure file share with the storage account key for the storage account containing
your Azure file share. A storage account key is an administrator key for a storage account, including
administrator permissions to all files and folders within the file share you’re accessing, and for all file shares and
other storage resources (blobs, queues, tables, etc) contained within your storage account.

QUESTION 66
Your company plans to migrate all its network resources to Azure.
You need to start the planning process by exploring Azure.
What should you create first?
A. a subscription
B. a resource group
C. a virtual network
D. a management group
Correct Answer: A
Section: Understand Core Azure Services
Explanation
Explanation/Reference:
Explanation:
The first thing you create in Azure is a subscription. You can think of an Azure subscription as an ‘Azure
account’. You get billed per subscription.
A subscription is an agreement with Microsoft to use one or more Microsoft cloud platforms or services, for
which charges accrue based on either a per-user license fee or on cloud-based resource consumption.
Microsoft’s Software as a Service (SaaS)-based cloud offerings (Office 365, Intune/EMS, and Dynamics 365)
charge per-user license fees.
Microsoft’s Platform as a Service (PaaS) and Infrastructure as a Service (IaaS) cloud offerings (Azure) charge
based on cloud resource consumption.
You can also use a trial subscription, but the subscription expires after a specific amount of time or
consumption charges. You can convert a trial subscription to a paid subscription.
Organizations can have multiple subscriptions for Microsoft’s cloud offerings.

QUESTION 68
You plan to deploy a website to Azure. The website will be accessed by users worldwide and will host large
video files.
You need to recommend which Azure feature must be used to provide the best video playback experience.
What should you recommend?
A. an application gateway
B. an Azure ExpressRoute circuit
C. a content delivery network (CDN)
D. an Azure Traffic Manager profile
Correct Answer: C
Section: Understand Core Azure Services
Explanation
Explanation/Reference:
Explanation:
The question states that users are located worldwide and will be downloading large video files. The video
playback experience would be improved if they can download the video from servers in the same region as the
users. We can achieve this by using a content deliver network.
A content delivery network (CDN) is a distributed network of servers that can efficiently deliver web content to
users. CDNs store cached content on edge servers in point-of-presence (POP) locations that are close to end
users, to minimize latency.
Azure Content Delivery Network (CDN) offers developers a global solution for rapidly delivering high-bandwidth
content to users by caching their content at strategically placed physical nodes across the world. Azure CDN
can also accelerate dynamic content, which cannot be cached, by leveraging various network optimizations
using CDN POPs. For example, route optimization to bypass Border Gateway Protocol (BGP).
The benefits of using Azure CDN to deliver web site assets include:
Better performance and improved user experience for end users, especially when using applications in
which multiple round-trips are required to load content.
Large scaling to better handle instantaneous high loads, such as the start of a product launch event.
Distribution of user requests and serving of content directly from edge servers so that less traffic is sent to
the origin server.

QUESTION 71
This question requires that you evaluate the underlined text to determine if it is correct.
You have an application that is comprised of an Azure web app that has a Service Level Agreement (SLA) of
99.95 percent and an Azure SQL database that has an SLA of 99.99 percent.
The composite SLA for the application is the product of both SLAs, which equals 99.94 percent.
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.
A. No change is needed
B. the lowest SLA associated to the application, which is 99.95 percent
C. the highest SLA associated to the application, which is 99.99 percent
D. the difference between the two SLAs, which is 0.05 percent
Correct Answer: A
Section: Understand Core Azure Services
Explanation
Explanation/Reference:

Explanation:
Composite SLAs involve multiple services supporting an application, each with differing levels of availability. For
example, consider an App Service web app that writes to Azure SQL Database. At the time of this writing, these
Azure services have the following SLAs:
App Service web apps = 99.95%
SQL Database = 99.99%
What is the maximum downtime you would expect for this application? If either service fails, the whole
application fails. The probability of each service failing is independent, so the composite SLA for this application
is 99.95% × 99.99% = 99.94%. That’s lower than the individual SLAs, which isn’t surprising because an
application that relies on multiple services has more potential failure points.

Correct Answer:

Section: Understand Core Azure Services
Explanation
Explanation/Reference:

Explanation:
Box 1: No
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.
Box 2: No
Tags for Resources are not inherited by default from their Resource Group
Box 3: Yes
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.

Azure storage offers different access tiers: hot, cool and archive.
The archive access tier has the lowest storage cost. But it has higher data retrieval costs compared to the hot
and cool tiers. Data in the archive tier can take several hours to retrieve.
While a blob is in archive storage, the blob data is offline and can’t be read, overwritten, or modified. To read or
download a blob in archive, you must first rehydrate it to an online tier.
Example usage scenarios for the archive access tier include:
Long-term backup, secondary backup, and archival datasets
Original (raw) data that must be preserved, even after it has been processed into final usable form.
Compliance and archival data that needs to be stored for a long time and is hardly ever accessed.
