AZ-720 Study Guide: Troubleshooting Microsoft Azure Connectivity

10 Min. Read

Are you preparing for the AZ-720 Azure Support Engineer for Connectivity Specialty certification? This study guide will share with you how to prepare and pass the AZ-720: Microsoft Certified Azure Support Engineer for Connectivity Specialty successfully (with links to exam objectives).

Introduction

Microsoft is keeping evolving its learning programs to help you and your career keep pace with today’s demanding IT environments. The new updated role-based certifications will help you to keep pace with today’s business requirements. Microsoft Learning is constantly evolving its learning program to better offer what you need to skill up, prove your expertise to employers and peers, and get the recognition—and opportunities you’ve earned.

After the recent announcement of the new certification exam that focuses on networking with the AZ-700 Designing and Implementing Microsoft Azure Networking Solutions, Microsoft Learning announced a new specialty certification exam for troubleshooting Microsoft Azure Connectivity which expands the Azure training and certification portfolio.

AZ-720 Exam Prep

How do you prepare for AZ-720?

While preparing to take this exam myself, I would like to share with you how to prepare and pass the AZ-720: Troubleshooting Microsoft Azure Connectivity exam successfully. To prepare for this exam, I usually use a couple of online resources, mainly Microsoft Docs, Microsoft Learn, and Training Labs, which I am going to share with you in the next section.

The exam is available starting end of March 2022 in the Beta phase at the time of this writing. Beta exams are not scored immediately because Microsoft is gathering data on the quality of the questions and the exam. I will update this article as soon as I get the exam results from Microsoft.

Since the AZ-720 Exam (Beta) won’t be released until the end of March 2022, you can start preparing for it now and get ready.

Updated on 29/04/2022  In this exam, I got around 56 questions in total with 2 case studies, 2 sections with Yes/No answers, and no lab questions but this might change in the future. The total time for this exam is 120 minutes (2 hours). The exam is very long, you need to manage your time and prepare very well. The questions do pretty much match the list of skills measured below.

Exam Target Audience

The candidates for the Azure Support Engineer for Connectivity Specialty certification are support engineers with subject matter expertise (SME) in using advanced troubleshooting methods to resolve networking and connectivity issues in Azure.

Professionals in this role troubleshoot hybrid environments, including issues with Azure Virtual Machines, virtual networks, and connectivity between on-premises and Azure services. They use
various tools and technologies to diagnose and identify root causes for complex network issues.

To prepare for this exam, you should have experience with networking and hybrid environments, including knowledge of routing, permissions, and account limits. You must be able to use available tools to diagnose issues related to business continuity, hybrid environments, Infrastructure as a Service (IaaS), Platform as a Service (PaaS), access control, networking, and virtual machines connectivity.

Please note that to prepare and take the AZ-720 exam, it’s highly recommended to have Azure networking skills. Check my AZ-700: Microsoft Azure Network Engineer Associate study guide to get prepared.

Prerequisites

Successful support engineers are professionals who have the energy and expertise to resolve difficult technical issues, and you can drive the resolution of highly complex incidents related to solutions development and deployment.

You should collaborate with other technical specialists on case reviews, troubleshooting, and effective customer interaction. As a prerequisite for this exam, you should be familiar with the following:

  • Own, troubleshoot, and solve technical issues, using collaboration, best practices, and transparency within and across teams.
  • Identify technical or strategic cases that require escalation.
  • Create and maintain incident management requests for the product group or engineering group.
  • Contribute to case deflection initiatives, automation, and other digital self-help assets to improve customer and engineer experience.
