Sample Questions
Answer: Reserved Instances provide significant cost savings (up to 72%) when you commit to using Azure VMs for 1 or 3 years. They are ideal for predictable, steady-state workloads.
Answer: Azure Kubernetes Service (AKS). It manages the Kubernetes control plane, so you only manage the worker nodes and applications.
Answer: Azure Policy enforces what can be deployed (resource configuration rules). RBAC controls who has access to resources and what they can do with them. Both are needed for complete governance.
Answer: An Availability Zone is a physically separate location within an Azure region. Each zone has independent power, networking, and cooling. Deploying across zones provides high availability.
Answer: Security is shared between the Azure provider and the customer. Azure secures the infrastructure (physical, network, hypervisor). The customer secures what they put on the infrastructure (data, identity, OS).
Answer: Archive storage tier. It is designed for data that is rarely accessed and stored for at least 180 days. Retrieval can take up to 15 hours.
Answer: Azure Advisor provides personalized recommendations to optimize your Azure deployments. It covers cost, security, reliability, performance, and operational excellence.
Answer: 99.9%. To achieve higher SLAs, use Availability Sets (99.95%) or deploy across Availability Zones (99.99%).
Time Strategy
- First pass — Answer all questions you know immediately. Do not spend more than 30 seconds on any question.
- Flag and return — Mark uncertain questions and come back after the first pass.
- Eliminate wrong answers — Even if unsure, eliminating two wrong answers gives you a 50% chance.
- Time check — At 20 minutes, you should have answered at least 20 questions.
Scoring and Passing
The passing score is 700 out of 1000. Microsoft uses scaled scoring, so the exact number of correct answers needed varies by exam version. You receive your score immediately after submission.
Guess if you do not know the answer. There is no penalty for incorrect answers. An educated guess is always better than leaving a question blank.
Last-Minute Tips
