AZ-900 Microsoft Azure Fundamentals Practice Tests 2022

AZ-900 Practice Tests OVERVIEW

Welcome! I’m here to help you prepare and PASS the newest Microsoft Azure Fundamentals AZ-900 Exam.

I feel that I need to point this out from the start, this course doesn’t include exam dumps! On the other hand, this course includes 5 full practice exams, 70% passing score, one hour to complete the test, just like in the real exam!

Why should you take this course?

• questions cover all topics included in the latest AZ-900 official exam blueprint (read more)
• in-depth explanations available for each and every question; screenshots from Azure official documentation, add-notations, reference links to Azure official documentation to continue learning and quick preview screenshots

Study, prepare, practice to gain hands-on skills … and you will pass any exam or upcoming job interview!

Ready for a sample question? Let’s go!

You are planning to create a new storage account, StorageAccount1, in your Azure subscription. Data in StorageAccount1 should be replicated three times and stored in different Azure data centers.

What redundancy option should you choose for your StorageAccount1?

Answer options:

• Locally redundant storage (LRS)
• Zone-redundant storage (ZRS)
• Geo-redundant storage (GRS)
• Geo-zone-redundant storage (GZRS)

What is your guess? What is the correct answer? Please evaluate the question and Scroll down for extended explanation. This is what you can expect with this course, while preparing for AZ-900 exam.

Explanation:

Azure Storage always stores multiple copies of your data so that it is protected from planned or unplanned events (hardware failures, network or power outages, natural disasters, etc.).

Redundancy ensures that your storage account meets its availability and durability targets, even if failure events take place.

Azure provides redundancy to your data by copying your files into multiple locations, either in the same region, or in the same region and an additional region as well.

• Redundancy in the same region is implemented if you choose Locally-redundant storage (LRS) or Zone-redundant storage (ZRS) replication
• Multi-region redundancy is implemented if you choose Geo-redundant storage (GRS) or Geo-zone-redundant storage (GZRS) replication.

Let’s now see how many copies of your data will be available in Azure, depending on the redundancy option chosen.

With Locally redundant storage (LRS), Azure will create 3 copies of your data, in the same data center (Availability Zone).

With Zone-redundant storage (ZRS), Azure will create 3 copies of your data, in 3 different data centers (Availability Zone), in the same region.

With Geo-redundant storage (GRS), Azure will create 6 copies of your data, 3 copies in a single data center (Availability Zone) in the first region (primary) and 3 copies in a single data center (Availability Zone) in the second region (secondary). This is basically 2x LRS, but in different regions.

With Geo-zone-redundant storage (GZRS), Azure will create 6 copies of your data, 3 copies of your data, in 3 different data centers (Availability Zone), in the first region (primary) and 3 copies of your data, in the same data center (Availability Zone), in the second region (secondary).

Alright, let’s get back to the scenario presented in this question.

Zone-redundant storage (ZRS) will create 3 copies of your data, in 3 different data centers (Availability Zone), in the same region and is the correct answer for this scenario.
