Your public-facing static website stores all its public UI images in blob storage. The website needs to
display the graphics without any kind of authorization. Which is the best option?



Public access



Shared key



Shared access signature - correct answer Public access



Public Access:

, Public access is a type of access policy for cloud storage services or resources, which allows anyone with
the resource's URL or endpoint to access the resource. Public access is often used for web content, such
as images, videos, and other static files that are intended to be publicly accessible.



Shared Key:

Shared Key is a type of access policy used for securing access to cloud storage services or resources. It is
a security mechanism that relies on a shared secret key between the client and the storage service. The
client must provide the shared key along with their request to access the resource, and the storage
service validates the key to determine if the request is authorized.



Shared Access Signature (SAS):

A Shared Access Signature (SAS) is another type of access policy used for securing access to cloud
storage services or resources. It is a secure way to grant limited access to a resource without exposing
the account key or requiring the user to authenticate with the storage service. A SAS token is generated
by the storage service and includes a set of permissions and an expiration time. The token can be used
by clients to access the resource for a specific period, after which the token expires, and the access is
revoked. SAS tokens can be revoked or regenerated at any time, providing fine-grained control over
resource access.



Which of these disk roles should you use to store a set of help videos that explain how to use the

OS Disk:

An OS (Operating System) Disk is a type of storage in a computer or server that stores the operating
system and related software files. It is the primary disk on which the computer boots, and it contains the
system files necessary to run the computer's hardware and software. It usually has a fixed size and is not
intended for storing data files or user data.
