Just as an old saying goes, it is better to gain a skill than to be rich. Contemporarily, competence far outweighs family backgrounds and academic degrees. One of the significant factors to judge whether one is competent or not is his or her DP-750 certificates. Generally speaking, DP-750 certificates function as the fundamental requirement when a company needs to increase manpower in its start-up stage. In this respect, our DP-750 practice materials can satisfy your demands if you are now in preparation for a DP-750 certificate.

NEW QUESTION # 92
You use Databricks Asset Bundles to manage two jobs and an app.
You need to deploy the bundle to development and production environments. The solution must meet the following requirements:
- Deploy the app to both environments.
- Deploy only one job to development.
- Minimize administrative effort.
What should you use?
Answer: B
Explanation:
To meet your deployment needs with minimal administrative overhead, you should use Databricks Asset Bundle (DAB) targets combined with resource overrides or conditional lookups using Go template syntax in your databricks.yml file.
Instead of creating separate bundles or complex CI/CD logic, you can declare both jobs and the app inside the main resources block, and then filter or modify them per target environment.
Implementation Options
Depending on your preference for keeping configuration declarative or fully conditional, choose one of the two standard patterns:
*-> Option 1: Resource Overrides via targets (Recommended)
Define all components globally, but use the targets block to remove or empty out the configuration of the job you want to skip in development.yamlbundle:
name: my-unified-bundle
apps:
my_app:
# App configurations go here...
jobs:
job_shared:
# Configurations for the job deployed to BOTH dev and prod...
job_prod_only:
name: Only for Production
# Production configurations...
targets:
dev:
mode: development
workspace:
host: https://dev-workspace.cloud.databricks.com
# Keep administrative work low by overriding the prod job to null/empty resources:
jobs:
job_prod_only: !null
prod:
mode: production
workspace:
host: https://prod-workspace.cloud.databricks.com
Option 2: Go Template Conditional LogicIf you prefer not to use !null overrides, you can evaluate the target environment dynamically at deployment time using standard Go templates.

NEW QUESTION # 93
You have an Azure Databricks workspace that contains a job in Lakeflow Jobs named Job1.
Job1 processes raw data files stored in Azure Storage.
New files arrive at unpredictable intervals.
You need to ensure that Job1 starts automatically when new files arrive and does NOT consume compute resources when no data is available.
Which type of job trigger should you use?
Answer: D
Explanation:
The File arrival trigger is exactly what you need for this use case. It natively solves your problem by launching a job the moment new files land in your Azure Storage container, automatically scaling down to zero compute when no data is processing.
Event-Driven: Instead of relying on a time-based schedule (cron) that wastes resources, the Lakeflow Job monitors the specific Azure location and starts exactly when new data appears.
Zero Idle Compute: You can use serverless compute or an ephemeral job cluster that spins up just for the duration of the run and terminates immediately after, meaning zero billing during downtime.
Cloud Cost Efficient: Listing files to detect new arrivals is typically free or fractions of a cent (only incurring minimal cloud provider API costs for listing the storage location).

NEW QUESTION # 94
You have an Azure Databricks workspace that is enabled for Unity Catalog.
You have a complex job named Job1 that contains eight tasks. Job1 takes multiple hours to complete.
During the last job run, the final task fails due to a transient issue.
You need to retry the last task without rerunning tasks that have already completed.
What should you do?
Answer: D
Explanation:
You can retry only the failed final task by using the Repair Run feature in Azure Databricks. This allows you to rerun failed or skipped tasks without restarting the successful ones, preserving your Unity Catalog data lineage and saving hours of compute time.

Hotspot Question
You have an Azure Databricks job named Job1 that contains an ingestion task named Task1 and transformation task named Task2.
You need to ensure that if Task1 fails, the task retries automatically, and Task2 is prevented from running.
How should you configure Job1? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.

NEW QUESTION # 96
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: A
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
