Microsoft AZ-400 (Designing and Implementing Microsoft DevOps Solutions) is a Microsoft DevOps expert certification. The 2026 exam syllabus is stable and the entire process is scenario based selection questions, without purely theoretical memorization content.

This guide helps you achieve rapid score improvement. The core is to grasp the three high scoring modules (accounting for 70% of the score), remember the mapping relationship between scenarios and solutions, and avoid losing points by efficiently solving questions and reviewing them. With a 7-day concentrated sprint, you can steadily break through the 700 point passing line.

1. Basic exam rules

Exam duration: 120 minutes; non-native speakers can apply to extend to 150 minutes

Question type and quantity: 40-60 questions, including single choice, multiple choice, drag and drop, and case analysis questions. Multiple-choice questions with missing or incorrect choices will not be scored

Passing score: 700 points, out of a total of 1000 points

Core feature: 100% scenario based decision-making, focusing on Azure DevOps, GitHub, IaC, DevSecOps, and container DevOps, without examining details of obscure commands

Iron rule for score improvement: 80/20 rule, with CI/CD, IaC, and DevSecOps modules covering 70% of the score. Giving up edge knowledge points can quickly improve scores

2. 7-day rapid score increase plan

Day 1 to Day 2: Conquer the CI/CD pipeline (30-35%)

Mastering Azure Pipelines, YAML prioritizes the core logic of classic pipelines and GitHub Actions, distinguishing between continuous integration/delivery/deployment scenarios, and mastering proxy pools, artifact management, and multi-stage release rules.

Day 3: Overcoming IaC and Configuration Management (20-25%)

Keeping in mind the selection boundary between iPadOS and Terraform, mastering the core scenarios of ARM, Azure Policy, and configuration drift repair is the core scoring point for Azure DevOps architecture questions.

Day 4: Conquer DevSecOps security compliance (15-20%)

Focus on security left shift, key management SAST/DAST, SBOM, and mirror scanning; all security related questions follow the principle of "security first, never hard coding."

Day 5: Overcoming Monitoring and Container DevOps (10-15%)

Master the basic selection of Azure Monitor, Application Insights, AKS DevOps, and cost optimization, and quickly pass low weight modules.

Day 6: Real exam practice + targeted review

Complete 2 sets of the latest fully realistic simulation questions, without worrying about difficult problems. Review and only make binding records for "scene keywords → correct options."

Day 7: Full Reality Model Exam + Recitation of Error prone Points

Complete the simulation of the 120 minute exam process, review all marked questions, memorize scene selection rules and avoidance checklist.

3. Must memorize high-frequency scoring test points

(1) CI/CD assembly line

Azure exclusive CI/CD prioritizes Azure Pipelines; GitHub ecosystem prioritizes GitHub Actions

Continuous integration: build+ automate testing; Continuous delivery: automatic deployment to testing environment, manual release to production; Continuous deployment: Automated deployment throughout the entire process

Customize the build environment using self hosted agents, and use Microsoft hosted agents for general scenarios

Container CI/CD fixed combination: ACR image storage + AKS deployment + image security scanning

(2) IaC and Configuration Management

IPadOS is preferred for Azure single cloud environments, and Terraform is preferred for multi cloud scenarios

Mandatory resource compliance using Azure Policy, fixing virtual machine configuration drift using Azure Automation DSC

Prioritize coding solutions for infrastructure configuration and reject manual configuration

(3) DevSecOps Security Compliance

Keys/certificates are definitely not hard coded and must be integrated with Azure Key Vault

SAST tool is used for code vulnerability scanning, and DAST tool is used for runtime vulnerabilities, both of which need to be integrated in the CI phase

SBOM is essential for compliance auditing, and ACR built-in scanning or Trivy is used for container mirroring

Implementing Secret Scanning and Dependency Detection for GitHub Code Security with GitHub Advanced Security

(4) Monitoring and optimization

Application Insights + Azure Monitor for Full Link Observation

AKS Container Insights for Monitoring Containers

DevOps cost optimization: automatic cleaning of non production environments and reserved instances for production environments

4. The Golden Rule of Reviewing Questions

Only use the latest real and official sample questions from 2026 to eliminate outdated question banks; If a single question lasts more than 90 seconds, mark it directly without wasting time; Wrong questions only record "scene keywords + correct options" without delving into the underlying principles; multiple-choice questions are sorted separately, remembering all correct options to avoid missing them; daily review of wrong questions for 30 minutes is much more efficient than learning new knowledge points.

5. Quick Tips for Exam Room Testing

Time allocation: Complete all questions in the first 80 minutes, process marked questions and check multiple-choice questions in the last 40 minutes

Topic review logic: First read the question, then read the question stem, and only capture the four core keywords of IaC, CI/CD, security, and container

Exclusion method priority: Exclude non Microsoft official solutions, exclude hard coded/insecure error options

Multiple choice strategy: Only select options that are 100% certain, and never check options that are uncertain

Case analysis question: Disassemble molecular problems, correspond modules one by one, and avoid global confusion

Summary: The core of the rapid improvement of AZ-400 scores in 2026 is to abandon comprehensive and systematic learning, focus on the three high scoring modules of CI/CD, IaC, and DevSecOps, memorize the mapping relationship between scenarios and solutions, and strengthen problem-solving logic through efficient problem-solving and review.
