AZURE
Pass the Azure Data Engineering Certification exam 2025/2026 with
confidence. This exam resource features questions in areas like: data
storage, processing, and security on Microsoft Azure. It is ideal for IT and
data engineering students preparing for cloud certification.
Difference between Azure Data Lake Gen 1 and Gen 2 ...... ANSWER
......Storage redundancies / failover (Gen1 only allows locally
redundant storage), Shared Access Keys, integration with latest
versions of HDInsight, Databricks, etc
Azure Storage Types ...... ANSWER ......Azure Blob, Azure Files,
Azure Queue, Azure Table
Azure Blob Storage Use Cases ...... ANSWER ......- Store data in blobs
and send blob urls in messages
- File system for storing docs
- Static web assets
- Cloud shell uses it
, Blobs ...... ANSWER ......"Files for the Cloud". Similar to file
storage, but can be accessed anywhere. Used in combination with
databases to store non-queryable data (profile pics)

Windowing Functions ...... ANSWER ......- Tumbling Window
- Hopping Window
- Sliding Window
- Session Window
Tumbling Window ...... ANSWER ......Segment stream into distinct
time segments (i/e 10 second windows), they repeat, do not overlap,
and each event can only belong to 1 window
Hopping Window ...... ANSWER ......Move forward in time by a
fixed period. Basically windows that overlap (show me the last 10
seconds every 5 seconds). Events can be part of more than one window
Sliding Window ...... ANSWER ......Product output ONLY when
event occurs. Each window has at least 1 event, and windows
continuously move forward. Events can belong to more than 1
window. "Topics tweeted more than 10 times in the last 10 seconds)
Session Window ...... ANSWER ......Groups events that arrive at
similar time, and filter out times with no data. Window begins when
first event occurs. If another event occurs within specified timeout
period, then it extends window. (Count of tweets that occur within 5
, mins of each other). Window lasts as long as the session. One window
per event

Polybase ...... ANSWER ......Access data stored in Blob Storage,
Hadoop, or Data Lake Storage using T-SQL
Steps to Implement Polybase ...... ANSWER ......1) Create an Import
Database scoped credential that secures credentials to storage
2) Create an external data source connection
3) Define the file import format
4) Create a temp table for staging
5) Create a destination table
6) Load the data
SQL Data Sync ...... ANSWER ......Synchronize data between SQL
Databases and Server instances on-prem vs. in Azure. Has higher
latency, no consistency, higher performance impact
Ambari Web UI ...... ANSWER ......Used to monitor HDInsight
Clusters
Which windowing functions allow only 1 window per event? (No
overlap?) ...... ANSWER ......Session, Tumbling Window
CosmosDB APIs ...... ANSWER ......- SQL API (Typical Use Case)
