The MS-102 Microsoft 365 Administrator exam is an expert-level exam in the Microsoft domain that is highly focused on the Security aspect of Microsoft 365 services and enables you to achieve the Microsoft 365 Certified: Administrator Expert certification. However, the exam outline covers many essential topics that you are expected to know in your day-to-day life regardless of everything.

In this article, you will find the resources and recommendations if you are preparing for the Microsoft 365 Administrator exam soon. This post is super long, so use the Table of Content to find the appropriate section you are interested in and bookmark it for later use. The study guide also includes the content in the Beta version since the MS-101 and MS-100 phase out on July 31, 2023, and is replaced by one MS-102 exam to achieve the Administrator Expert certification.

Certification Overview

Microsoft 365 Administrator (MS-102) is an associate-level exam that validates the skills and expertise of subject matter experts working with workload management, security, infrastructure, identity, compliance, endpoint, and applications in Microsoft 365 workloads.

The exam aims to validate that you understand how to implement and administer the cloud and hybrid environments using Microsoft 365 tools. It also tests your skills in networking, server administration, DNS, and usage of PowerShell while managing the M365 workloads.

Although, right now only one exam is required to achieve the Microsoft 365 Administrator Expert certification unlike before where you’d have to do two exams MS-100 and MS-101. I completed my exam in the Beta phase, however, the experience will be the same when the exam is released to the general audience in May 2023.

Exam Prerequisites

If you are planning to attempt the Microsoft 365 Administrator Expert exam, be sure to complete one of the following exams beforehand, as it will give you enough exposure to Microsoft 365 services and offerings:

It’s good to know the following concepts before going into the exam:

  • Basic understanding of TCP/IP, DNS, Firewall, and Routing
  • Familiar with PowerShell and Microsoft365 management commands
  • Understanding security and infrastructure components of Microsoft 365 services

Who is this MS-102 Exam for?

On a high-level note, take the exam:

  • If you are looking to learn more about Networking, Infrastructure, and Security in Azure cloud services.
  • If you are working on M365 Administration, App development and looking for a chance to grow and learn more about Microsoft 365 services.
  • If you are looking to build your network skills and learn to use multiple networking services in the cloud effectively.

What to Expect in the Exam?

The Microsoft 365 Administrator Exam is 150 minutes, including about 30 minutes for the surveys and the assessments, which gives you roughly 120 minutes for the exam. I did find it a little challenging to finish the exam within the time frame. You can expect around 50-60 questions in the exam.

One of the most interesting features I’ve seen in the recent Microsoft Exam is the “Break” feature. You can now take breaks during the exam if you need to pause for any moment. However, the exam counter does not stop, and when you return back from the break, you cannot attempt the questions you’ve already seen before going to the break. So keep that in mind before taking the break. I’d recommend not looking at all the questions in one go just in case you do decide to take a break later in the exam.

The structure of the exam can vary and range between:

  • Case study with multiple questions including two choices and drag-and-drop items.
  • Single-choice questions may not be skipped or reviewed. You only get to answer these questions ONCE.
  • Single-choice questions (True/False or Yes/No)
  • Multiple-choice questions

Since it’s an expert-level exam, it is relatively challenging as it covers many different topics and best practices. Therefore, I recommend you have at least 1-2 years of hands-on experience with Microsoft 365 Administration and Management in general before you consider booking the exam.

Exam Preparation Recommendations

There’s definitely a lot to cover in this exam, and giving you any list of services or things to learn would be unfair as the expectations for this exam are high. However, below are some topics to consider and focus attention on while preparing for the exam.

  • Understanding various license types for M365 services
  • Managing M365 and Azure AD users and groups along with roles and access
  • Understanding guest access and how it works with M365 services
  • Configuring and managing a Hybrid AD environment with AD Connect
  • Implementing various authentication methods for a tenant in Cloud and Hybrid mode
  • Familiarity with Microsoft 365 Defender service and understanding it’s functionality
  • Managing Microsoft Purview and implementing compliance functionality for a tenant

Exam Day Tips

Below are some of my recommendations on the exam and some tips that might be helpful.

  • Cover basic knowledge using MD-102 and SC-300 exams to familiarize yourself with the Microsoft 365 offerings.
  • Book the exam at least 60-90 days ahead of time. Try to use the vouchers from a learning partner, or keep an eye for open Cloud Skill Challenges that are often offered via Microsoft.
  • If it’s your first time doing a Virtual Exam, be sure to read PearsonVUE’s exam information to ensure your desk and workspace are clean before going into the exam.
  • The time for when to schedule the exam is debatable. If you are a morning person, consider doing it early when your mind is not distracted from the day’s stuff. On the other hand, I’ve had challenges with wait time and schedule in the evenings or afternoon PST time zones.
  • You have access to a whiteboard where you can brainstorm ideas about the exams. It has been the least used feature of the exam for me personally.
  • Adjust the brightness of your screen or turn on Dark Mode before the exam starts. Constantly looking at a white screen with high brightness may affect your focus. Consider changing to dark mode from around the bottom left when you begin.
  • Use the Exam Outline to note down your target dates for each module and section so that you keep yourself on track. For example, I usually pick a final date and work backward to calculate how much time I spend on each module and section.
