NEW QUESTION # 39
You have an Azure Databricks workspace that contains a Delta table named Table1.
Table1 has accumulated obsolete files.
You need to reduce storage costs. The solution must preserve 30 days of time travel history.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
Answer: B,D
Explanation:
To diminish storage costs while preserving 60 days of time travel history, you must perform the following two actions: Set the delta.deletedFileRetentionDuration table property to 60 days and Run the vacuum command on the table.
Set the delta.deletedFileRetentionDuration table property to 30 days
This property controls how long data files must be deleted before they become eligible for removal by a cleanup process. By default, it is set to 7 days. Increasing it to 60 days ensures that Delta Lake preserves the underlying parquet files required to query any historical snapshot within your 30-day time travel window.
Run the vacuum command on the tableChanging the retention property alone does not delete files or reduce costs. You must explicitly execute the VACUUM command. The command scans the table and permanently deletes uncommitted or deleted data files that are older than the 60- day threshold defined by your retention duration, thereby freeing up storage space.
Incorrect:
[Not C]
Set the delta.logRetentionDuration table property to 30 days
This property controls how long the transaction log (_delta_log) history is kept, which defaults to
30 days. While the transaction log is required for time travel, modifying this property alone does not delete the heavy data files causing high storage costs. Furthermore, it governs the logs rather than the actual deleted data files.

NEW QUESTION # 40
You manage Declarative Automation Bundles by using the Databricks CLI.
You run the following command in a terminal window.
databricks bundle init
What occurs when you run the command?
Answer: D
Explanation:
The databricks bundle init command initializes a new bundle project from a selected default or custom project template. It prompts for relevant project values and creates the local project structure and starter configuration files. It does not deploy resources; deployment is performed with databricks bundle deploy. It does not merely validate an existing configuration, because validation uses databricks bundle validate. Running deployed bundle resources requires databricks bundle run followed by the resource key. The distinction matters in an automated bundle lifecycle: initialization scaffolds the project, validation checks configuration, deployment creates or updates workspace resources, and run starts a configured job or pipeline. Therefore, option A accurately describes the initialization command's function. Microsoft Learn
NEW QUESTION # 41
You have an Azure Databricks workspace named Workspace! that uses a Git repository. The repository contains a Databricks notebook named Notebook1.
From the main branch, you create a feature branch named Branch! and commit changes to Notebooks Another user commits changes to Notebook1 in main.
When you attempt to merge Branch! into main, the merge fails due to conflicts.
You need to merge Branch! into the main branch. The solution must ensure that Notebook1 includes all the changes from both the branches.
What should you do?
Answer: D
Explanation:
The correct answer is D - apply the main branch changes to Branch1 and resolve the conflicts.
When a merge fails due to conflicts, the right workflow is to bring main's changes into the feature branch, resolve conflicts there, and then merge the clean feature branch into main. This is the standard Git conflict resolution pattern - resolve in the feature branch, not in main - because it protects the main branch from partial or broken states during resolution.
Option A (clone Branch1 as a new repository) creates a disconnected copy; it doesn't resolve the conflict and breaks the relationship with the remote. Option B (apply changes directly to main) bypasses the feature branch entirely and risks overwriting the other developer's work. Option C (clone main as a new repository) again creates a disconnected copy - none of Branch1's changes would be incorporated, and history would be lost.

NEW QUESTION # 42
You have an Azure Databricks workspace that uses Unity Catalog.
You have a Lakeflow Spark Declarative Pipelines (SDP) pipeline that ingests data into a managed Delta table named Table1. Table! is used for analytics.
New columns are added to the source data, causing pipeline failures during writes to Table!
You need to prevent the pipeline failures. The solution must ensure that schema changes are detected and handled.
What should you do?
Answer: B
NEW QUESTION # 43
You have a Lakeflow Spark Declarative Pipelines (SDP) pipeline in Azure Databricks. The pipeline ingests transaction data into a table named Table1.
You need to ensure that in the event of an invalid record, the pipeline continues to run. The solution must meet the following requirements:
- Invalid records must NOT be written to Table1.
- Invalid records must be preserved for review.
- Minimize development effort.
What should you do?
Answer: A
Explanation:
To meet your pipeline requirements, use the expect_or_drop expectation constraint to ensure invalid records are not written to the table while allowing the pipeline to continue running. To preserve and review invalid records without custom development, capture the failed rows by isolating the inverse rule (expect_or_drop) in a quarantine flow.
Summary of the Behavior Matrix
Pipeline continues to run: Achieved via drop or warn behaviors (the fail policy is excluded because it halts execution).
Invalid records not written to the clean table: Achieved via the drop policy, which discards records from the downstream dataset.
Records preserved for review: Achieved by querying the automated, built-in Lakeflow Event Log Delta table, which automatically captures the details of any rejected or flagged rows without requiring custom code.
Minimized development: Eliminates the need to construct secondary "quarantine" storage tables manually.
