Overview
Litware, Inc. is a United States-based grocery retailer. Litware has a main office and a primary
datacenter in Seattle. The company has 50 retail stores across the United States and an emerging
online presence. Each store connects directly to the internet.
Existing environment. Cloud and Data Service Environments.
Litware has an Azure subscription that contains the resources shown in the following table.
Each container in productdb is configured for manual throughput.
The con-product container stores the company's product catalog data. Each document in con-product
includes a con-productvendor value. Most queries targeting the data in con-product are in the
following format.
SELECT * FROM con-product p WHERE p.con-productVendor - 'name'
Most queries targeting the data in the con-productVendor container are in the following format
SELECT * FROM con-productVendor pv
ORDER BY pv.creditRating, pv.yearFounded
Existing environment. Current Problems.
Litware identifies the following issues:
Updates to product categories in the con-productVendor container do not propagate automatically
to documents in the con-product container.
Application updates in con-product frequently cause HTTP status code 429 "Too many requests". You
discover that the 429 status code relates to excessive request unit (RU) consumption during the
updates.
Requirements. Planned Changes
Litware plans to implement a new Azure Cosmos DB Core (SQL) API account named account2 that
will contain a database named iotdb. The iotdb database will contain two containers named con-iot1
and con-iot2.
Litware plans to make the following changes:
Store the telemetry data in account2.
Configure account1 to support multiple read-write regions.
Implement referential integrity for the con-product container.
Use Azure Functions to send notifications about product updates to different recipients.
Develop an app named App1 that will run from all locations and query the data in account1.
Develop an app named App2 that will run from the retail stores and query the data in account2.
App2 must be limited to a single DNS endpoint when accessing account2.
Requirements. Business Requirements
Litware identifies the following business requirements:
Whenever there are multiple solutions for a requirement, select the solution that provides the best
performance, as long as there are no additional costs associated.
Ensure that Azure Cosmos DB costs for IoT-related processing are predictable.
Minimize the number of firewall changes in the retail stores.
Requirements. Product Catalog Requirements
Litware identifies the following requirements for the product catalog:
Implement a custom conflict resolution policy for the product catalog data.
Minimize the frequency of errors during updates of the con-product container.
Once multi-region writes are configured, maximize the performance of App1 queries against the data
in account1.
Trigger the execution of two Azure functions following every update to any document in the con-
product container.

Overview
Litware, Inc. is a United States-based grocery retailer. Litware has a main office and a primary
datacenter in Seattle. The company has 50 retail stores across the United States and an emerging
online presence. Each store connects directly to the internet.
Existing environment. Cloud and Data Service Environments.
Litware has an Azure subscription that contains the resources shown in the following table.
Each container in productdb is configured for manual throughput.
The con-product container stores the company's product catalog data. Each document in con-product
includes a con-productvendor value. Most queries targeting the data in con-product are in the
following format.
SELECT * FROM con-product p WHERE p.con-productVendor - 'name'
Most queries targeting the data in the con-productVendor container are in the following format
SELECT * FROM con-productVendor pv
ORDER BY pv.creditRating, pv.yearFounded
Existing environment. Current Problems.
Litware identifies the following issues:
Updates to product categories in the con-productVendor container do not propagate automatically
to documents in the con-product container.
Application updates in con-product frequently cause HTTP status code 429 "Too many requests". You
discover that the 429 status code relates to excessive request unit (RU) consumption during the
updates.

Overview
Litware, Inc. is a United States-based grocery retailer. Litware has a main office and a primary
datacenter in Seattle. The company has 50 retail stores across the United States and an emerging
online presence. Each store connects directly to the internet.
Existing environment. Cloud and Data Service Environments.
Litware has an Azure subscription that contains the resources shown in the following table.
Each container in productdb is configured for manual throughput.
The con-product container stores the company's product catalog data. Each document in con-product
includes a con-productvendor value. Most queries targeting the data in con-product are in the
following format.
SELECT * FROM con-product p WHERE p.con-productVendor - 'name'
Most queries targeting the data in the con-productVendor container are in the following format
SELECT * FROM con-productVendor pv
ORDER BY pv.creditRating, pv.yearFounded
Existing environment. Current Problems.
Litware identifies the following issues:
Updates to product categories in the con-productVendor container do not propagate automatically
to documents in the con-product container.
Application updates in con-product frequently cause HTTP status code 429 "Too many requests". You
discover that the 429 status code relates to excessive request unit (RU) consumption during the
updates.
Requirements. Planned Changes
Litware plans to implement a new Azure Cosmos DB Core (SQL) API account named account2 that
will contain a database named iotdb. The iotdb database will contain two containers named con-iot1
and con-iot2.
Litware plans to make the following changes:
Store the telemetry data in account2.
Configure account1 to support multiple read-write regions.
Implement referential integrity for the con-product container.
Use Azure Functions to send notifications about product updates to different recipients.
Develop an app named App1 that will run from all locations and query the data in account1.
Develop an app named App2 that will run from the retail stores and query the data in account2.
App2 must be limited to a single DNS endpoint when accessing account2.
Requirements. Business Requirements
Litware identifies the following business requirements:
Whenever there are multiple solutions for a requirement, select the solution that provides the best
performance, as long as there are no additional costs associated.
Ensure that Azure Cosmos DB costs for IoT-related processing are predictable.
Minimize the number of firewall changes in the retail stores.
Requirements. Product Catalog Requirements
Litware identifies the following requirements for the product catalog:
Implement a custom conflict resolution policy for the product catalog data.
Minimize the frequency of errors during updates of the con-product container.
Once multi-region writes are configured, maximize the performance of App1 queries against the data
in account1.
Trigger the execution of two Azure functions following every update to any document in the con-
product container.
You need to select the capacity mode and scale configuration for account2 to support the planned
changes and meet the business requirements. What should you select? To answer, select the
appropriate options in the answer are
a. NOTE: Each correct selection is worth one point.

Question 9/109/10
You have an application named App1 that reads the data in an Azure Cosmos DB Core (SQL) API
account. App1 runs the same read queries every minute. The default consistency level for the
account is set to eventual.
You discover that every query consumes request units (RUs) instead of using the cache.
You verify the IntegratedCacheiteItemHitRate metric and the IntegratedCacheQueryHitRate metric.
Both metrics have values of 0.
You verify that the dedicated gateway cluster is provisioned and used in the connection string.
You need to ensure that App1 uses the Azure Cosmos DB integrated cache.
What should you configure?
