You need to configure Azure CDN for the Shipping web site.
Which configuration options should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation
Scenario: Shipping website
Use Azure Content Delivery Network (CDN) and ensure maximum performance for dynamic content while minimizing latency and costs.
Tier: Standard
Profile: Akamai
Optimization: Dynamic site acceleration
Dynamic site acceleration (DSA) is available for Azure CDN Standard from Akamai, Azure CDN Standard from Verizon, and Azure CDN Premium from Verizon profiles.
DSA includes various techniques that benefit the latency and performance of dynamic content. Techniques include route and network optimization, TCP optimization, and more.
You can use this optimization to accelerate a web app that includes numerous responses that aren't cacheable.
Examples are search results, checkout transactions, or real-time data. You can continue to use core Azure CDN caching capabilities for static data.

You develop an HTTP triggered Azure Function app to process Azure Storage blob dat
a. The app is triggered using an output binding on the blob.
The app continues to time out after four minutes. The app must process the blob data.
You need to ensure the app does not time out and processes the blob data.
Solution: Use the Durable Function async pattern to process the blob data.
Does the solution meet the goal?
- A. Yes
- B. No
Answer: B
Explanation:
Instead pass the HTTP trigger payload into an Azure Service Bus queue to be processed by a queue trigger function and return an immediate HTTP success response.
Note: Large, long-running functions can cause unexpected timeout issues. General best practices include:
Whenever possible, refactor large functions into smaller function sets that work together and return responses fast. For example, a webhook or HTTP trigger function might require an acknowledgment response within a certain time limit; it's common for webhooks to require an immediate response. You can pass the HTTP trigger payload into a queue to be processed by a queue trigger function. This approach lets you defer the actual work and return an immediate response.

You develop a software as a service (SaaS) offering to manage photographs. Users upload photos to a web service which then stores the photos in Azure Storage Blob storage. The storage account type is General-purpose V2.
When photos are uploaded, they must be processed to produce and save a mobile-friendly version of the image. The process to produce a mobile-friendly version of the image must start in less than one minute.
You need to design the process that starts the photo processing.
Solution: Trigger the photo processing from Blob storage events.
Does the solution meet the goal?
- A. Yes
- B. No
Answer: B
Explanation:
You need to catch the triggered event, so move the photo processing to an Azure Function triggered from the blob upload Note: Azure Storage events allow applications to react to events.
Common Blob storage event scenarios include image or video processing, search indexing, or any file-oriented workflow.
Events are pushed using Azure Event Grid to subscribers such as Azure Functions, Azure Logic Apps, or even to your own http listener.
Note: Only storage accounts of kind StorageV2 (general purpose v2) and BlobStorage support event integration. Storage (general purpose v1) does not support integration with Event Grid.

NEW QUESTION # 66
You are developing a .Net Core application that manages images for an advertising company.
The images are stored in blob storage with read access geo-zone-redundant storage (RA-GZRS) redundancy to achieve high availability and maximum durability. In case of regional outage, the application should be able to read data from secondary storage replication. Secondary storage replication should only be used if primary storage is unavailable.
You develop the following code to create the object responsible for uploading and reading images from blob storage:
string storageConnectionString =
Environment.GetEnvironmentVariable("storageconnectionstring");
CloudStorageAccount storageAccount =
CloudStorageAccount.Parse(storageConnectionString);
blobClient = storageAccount.CreateCloudBlobClient();
You need to configure the blob client to meet the high availability requirement.
Which location mode option should you use?
- A. blobClient.DefaultRequestOptions.LocationMode = LocationMode.SecondaryThenPrimary;
- B. blobClient.DefaultRequestOptions.LocationMode = LocationMode.SecondaryOnly;
- C. blobClient.DefaultRequestOptions.LocationMode = LocationMode.PrimaryThenSecondary;
- D. blobClient.DefaultRequestOptions.LocationMode = LocationMode.PrimaryOnly;
Answer: C
Explanation:
You should configure the blob client default request option for the location mode as PrimaryThenSecondary. In this mode, in case of a regional outage affecting primary storage, the application reads the images replicated to another region as a fallback until primary storage is available again.
You should not configure the blob client default request option for the location mode as PrimaryOnly. In this mode, only primary storage is used. In case of a regional outage affecting primary storage, the application will fail to read images even if they are replicated to secondary storage. This is the default blob client mode.
You should not configure the blob client default request option for the location mode as SecondaryOnly or SecondaryThenPrimary. With these modes, the blob client will first read the images from secondary storage. Secondary storage should only be used if primary storage is unavailable.

- C. Enable blob versioning for the storage account. Use an Azure Function to process a list of the blob versions per day.
- D. Process an Azure Storage blob inventory report by using an Azure Function. Create rule filters on the blob inventory report,
- E. Subscribe to blob storage events by using an Azure Function and Azure Event Grid. Filter the events by store location.

NEW QUESTION # 68
You are developing an application to store and retrieve data in Azure Blob storage. The application will be hosted in an on-premises virtual machine (VM). The VM is connected to Azure by using a Site-to-Site VPN gateway connection. The application is secured by using Azure Active Directory (Azure AD) credentials.
The application must be granted access to the Azure Blob storage account with a start time, expiry time, and read permissions. The Azure Blob storage account access must use the Azure AD credentials of the application to secure data access. Data access must be able to be revoked if the client application security is breached.
You need to secure the application access to Azure Blob storage.
Which security features should you use? To answer select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation
Text, letter Description automatically generated
Box 1: Shared access signature (SAS) token
When your application design requires shared access signatures for access to Blob storage, use Azure AD credentials to create a user delegation SAS when possible for superior security.
Box 2: Stored access policy
Stored access policies give you the option to revoke permissions for a service SAS without having to regenerate the storage account keys.
A shared access signature can take one of the following two forms:
* Service SAS with stored access policy. A stored access policy is defined on a resource container, which can be a blob container, table, queue, or file share. The stored access policy can be used to manage constraints for one or more service shared access signatures. When you associate a service SAS with a stored access policy, the SAS inherits the constraints - the start time, expiry time, and permissions - defined for the stored access policy.
* Ad hoc SAS.
