An S3 shortcut with workspace caching enabled minimizes egress without persisting raw data

Ingest and transform batch data
Answer Correct answer: D - A shortcut references the S3 data without copying it, and caching minimizes egress; the cache is temporary, not a persisted raw copy.

Company Overview - Contoso, Ltd. is an online retail company that wants to modernize its analytics platform by moving to Fabric. The company plans to begin using Fabric for marketing analytics. Overview. IT Structure - The company’s IT department has a team of data analysts and a team of data engineers that use analytics systems. The data engineers perform the ingestion, transformation, and loading of data. They prefer to use Python or SQL to transform the data. The data analysts query data and create semantic models and reports. They are qualified to write queries in Power Query and T-SQL. Existing Environment. Fabric - Contoso has an F64 capacity named Cap1. All Fabric users are allowed to create items. Contoso has two workspaces named WorkspaceA and WorkspaceB that currently use Pro license mode. Existing Environment. Source Systems Contoso has a point of sale (POS) system named POS1 that uses an instance of SQL Server on Azure Virtual Machines in the same Microsoft Entra tenant as Fabric. The host virtual machine is on a private virtual network that has public access blocked. POS1 contains all the sales transactions that were processed on the company’s website. The company has a software as a service (SaaS) online marketing app named MAR1. MAR1 has seven entities. The entities contain data that relates to email open rates and interaction rates, as well as website interactions. The data can be exported from MAR1 by calling REST APIs. Each entity has a different endpoint. Contoso has been using MAR1 for one year. Data from prior years is stored in Parquet files in an Amazon Simple Storage Service (Amazon S3) bucket. There are 12 files that range in size from 300 MB to 900 MB and relate to email interactions. Existing Environment. Product Data POS1 contains a product list and related data. The data comes from the following three tables: Products - ProductCategories - ProductSubcategories - In the data, products are related to product subcategories, and subcategories are related to product categories. Existing Environment. Azure - Contoso has a Microsoft Entra tenant that has the following mail-enabled security groups: DataAnalysts: Contains the data analysts DataEngineers: Contains the data engineers Contoso has an Azure subscription. The company has an existing Azure DevOps organization and creates a new project for repositories that relate to Fabric. Existing Environment. User Problems The VP of marketing at Contoso requires analysis on the effectiveness of different types of email content. It typically takes a week to manually compile and analyze the data. Contoso wants to reduce the time to less than one day by using Fabric. The data engineering team has successfully exported data from MAR1. The team experiences transient connectivity errors, which causes the data exports to fail. Requirements. Planned Changes - Contoso plans to create the following two lakehouses: Lakehouse1: Will store both raw and cleansed data from the sources Lakehouse2: Will serve data in a dimensional model to users for analytical queries Additional items will be added to facilitate data ingestion and transformation. Contoso plans to use Azure Repos for source control in Fabric. Requirements. Technical Requirements The new lakehouses must follow a medallion architecture by using the following three layers: bronze, silver, and gold. There will be extensive data cleansing required to populate the MAR1 data in the silver layer, including deduplication, the handling of missing values, and the standardizing of capitalization. Each layer must be fully populated before moving on to the next layer. If any step in populating the lakehouses fails, an email must be sent to the data engineers. Data imports must run simultaneously, when possible. The use of email data from the Amazon S3 bucket must meet the following requirements: Minimize egress costs associated with cross-cloud data access. Prevent saving a copy of the raw data in the lakehouses. Items that relate to data ingestion must meet the following requirements: The items must be source controlled alongside other workspace items. Ingested data must land in the bronze layer of Lakehouse1 in the Delta format. No changes other than changes to the file formats must be implemented before the data lands in the bronze layer. Development effort must be minimized and a built-in connection must be used to import the source data. In the event of a connectivity error, the ingestion processes must attempt the connection again. Lakehouses, data pipelines, and notebooks must be stored in WorkspaceA. Semantic models, reports, and dataflows must be stored in WorkspaceB. Once a week, old files that are no longer referenced by a Delta table log must be removed. Requirements. Data Transformation In the POS1 product data, ProductID values are unique. The product dimension in the gold layer must include only active products from product list. Active products are identified by an IsActive value of 1. Some product categories and subcategories are NOT assigned to any product. They are NOT analytically relevant and must be omitted from the product dimension in the gold layer. Requirements. Data Security - Security in Fabric must meet the following requirements: The data engineers must have read and write access to all the lakehouses, including the underlying files. The data analysts must only have read access to the Delta tables in the gold layer. The data analysts must NOT have access to the data in the bronze and silver layers. The data engineers must be able to commit changes to source control in WorkspaceA. You need to ensure that usage of the data in the Amazon S3 bucket meets the technical requirements. What should you do?

  1. Create a workspace identity and enable high concurrency for the notebooks.
  2. Create a shortcut and ensure that caching is disabled for the workspace.
  3. Create a workspace identity and use the identity in a data pipeline.
  4. Create a shortcut and ensure that caching is enabled for the workspace. Correct Answer

Community Insight

Shortcut caching reduces cross-cloud egress by keeping temporary (24-hour default retention) copies of externally read files in the workspace cache, while the shortcut itself ensures no raw data is saved in the lakehouses.

Creating a shortcut references the Amazon S3 email data without copying it into the lakehouses, and enabling shortcut caching for the workspace serves repeated reads from a temporary cache, minimizing cross-cloud egress costs.

Disabling caching to avoid any copy; the cache is a temporary read cache separate from lakehouse storage, and disabling it forces every read to re-fetch from S3, maximizing egress costs.

Enabling caching for the workspace will help minimize egress costs by reducing the amount of data that needs to be transferred across clouds. Creating a shortcut ensures that the raw data is not duplicated in the lakehouse.

The use of email data from the Amazon S3 bucket must meet the following requirements: - Minimize egress costs associated with cross-cloud data access -> B or D - Prevent saving a copy of the raw data in the lakehouses -> B (no caching)
Kiket2ride 👍 1 Selected: D
Correct answer is D because you need to minimize egress cost and at the same time you don't store data in raw because cache on means the data stays there for no more than 28 days
vish9 👍 1 Selected: B
Caching should be disabled.
DarkDerf 👍 2 Selected: B
NOT "D": Create a shortcut and ensure that caching is enabled for the workspace. Enabling caching would store temporary copies of the data in Fabric, which contradicts the requirement to prevent storing raw data in the lakehouses. Final Answer: ✅ B. Create a shortcut and ensure that caching is disabled for the workspace.
Sunnyb 👍 1 Selected: B
The correct answer is B. Create a shortcut and ensure that caching is disabled for the workspace Create a shortcut: A shortcut allows you to reference data in the Amazon S3 bucket without copying the data into the lakehouse. This meets the requirement to prevent saving a copy of the raw data in the lakehouses. Ensure that caching is disabled for the workspace: Disabling caching ensures that the data is accessed directly from the Amazon S3 bucket, minimizing egress costs associated with cross-cloud data access. Answer isn't D because: Enabling caching would result in data being copied to the lakehouse, which violates the requirement to prevent saving a copy of the raw data.

shortcut creation and caching is available for Amazon S3 bucket and ADLS; reduces egress costs and also makes sure no data duplication done!

Expert Analysis

Why the Answer Is Correct

The two requirements are minimizing egress costs and preventing a saved copy of the raw data. A shortcut is a metadata reference, so the S3 files are never saved in the lakehouses as data. Enabling shortcut caching means files read through the shortcut are stored in a temporary workspace cache (24-hour default retention, configurable up to 28 days), so subsequent reads are served from cache instead of re-downloading from Amazon S3, directly minimizing cross-cloud egress.

Why the Other Options Are Wrong

Option B (caching disabled) still avoids a raw copy, but every read fetches the data from S3 again, failing the egress-minimization requirement. Options A and C (workspace identity) control the authentication identity for notebook and pipeline runs, not how the S3 data is accessed, and neither prevents nor minimizes anything on its own.

Community Comment Notes

The vote is D 82 vs B 18. GHill1982 (12 likes) explains caching minimizes egress while the shortcut prevents duplication, and Kiket2ride notes the cache retention is temporary (up to 28 days). DarkDerf argues any cached copy contradicts the no-raw-copy requirement, but the cache is a temporary read cache, not data saved in the lakehouses.
