Master network security groups (NSGs) in Azure: understand inbound and outbound rules, default rules for virtual networks, internet, and load balancer, and how to attach NSGs to NICs or subnets.

Explore how application security groups simplify network security management by enabling defense in depth, linking resources across subnets, and isolating compromised machines through reassignment to quarantine or web servers.

Explore core Azure identity services powered by Azure Active Directory, covering authentication vs authorization, multi-factor authentication, roles, users, groups, subscriptions, and monitoring for secure on premise and cloud access.

Learn how Azure information protection uses labels to classify and protect documents and emails, and how Azure Advanced Threat Protection monitors user behavior to detect attacks and prevent data leakage.

Explore how Azure Security Center unifies security data across on-premises and cloud to detect, respond, and protect with policy, compliance, and resource hygiene.

Explore Azure Key Vault for secrets, keys, and certificates; learn how secrets secure passwords, how keys protect data at rest, and how certificates secure data in transit.

Explore Azure governance, focusing on role-based access control, policies, and initiatives that enforce compliance and manage access to resources. Understand default deny, assignments, and policy definitions shaping security.

Explore Azure monitoring and service health across global, service, and resource levels, focusing on availability, metrics versus logs, and how alerts enable proactive resource troubleshooting.

Explore Azure privacy, compliance, and data protection standards, including the Service Trust portal, Trust Center, ISO 27001/27017/27018, GDPR, and FedRAMP, plus regional Germany considerations and shared responsibility for workloads.

Explore Azure subscriptions, including free trial and pay as you go, and learn how an Active Directory can be trusted by multiple subscriptions while each subscription trusts a single directory.

This lecture compares the pricing calculator to the TCO and demonstrates pricing for six Azure services, highlighting region, tier, redundancy, data transfer, and reserved pricing.

Use the Total Cost of Ownership (TCO) calculator to estimate savings from migrating on-prem workloads to Azure, detailing compute, storage, networking, and IT labor costs.

Discover starting with the Azure free account, 30-day credits, and pay-as-you-go access to 12-month free services; optimize costs using the pricing calculator, reserved instances, and Azure Advisor recommendations.

Explore Azure support plans—basic, developer, standard, and professional—and their severity levels. Learn how to submit requests and use the knowledge center and forums.

Understand Azure's service level agreements, including uptime commitments, regional consistency, and service categories. Learn the typical availability levels from 99.95 to 100 percent, with VM configurations and premium storage specifics.

Explore the top five cloud concepts: public vs private cloud, IaaS vs PaaS, serverless computing, CapEx vs OpEx, and high availability versus fault tolerance, with Azure DNS as a reference.

Explore five Azure fundamentals: regions and availability zones, storage file share versus Azure disk, structured vs unstructured data, virtual networks with subnets and network security groups, policy versus initiatives.

Learn how Azure secures access with identity services, authentication (MFA), and authorization (RBAC), uses key vault for secrets and certificates, and supports ISO and GDPR compliance with monitoring.

Compare TCO and pricing calculators to analyze on-prem costs versus Azure, and outline Azure subscriptions, trial limits, pay-as-you-go, support plans, and SLA expectations.

Explore the top seven exam feedback for azure fundamentals, covering resource locking, ad limits, licensing, identity protection with encryption, app service limits, and analytics with sql database and data lake.

Review topics you’re unsure about, post questions, and register for the exam on the Microsoft site; take it from home or a local center, and read every question carefully.
