Reseña del libro "Exam SC-900 (en Inglés)"
Prepare for Exam SC-900 with an independent study guide built around the public Microsoft skills outline and 107 hash-locked Microsoft Learn sources. The book connects security, compliance, and identity principles to the Microsoft cloud capabilities candidates are expected to recognize and distinguish. It explains the shared-responsibility model, zero trust, defense in depth, encryption, data residency, authentication, authorization, federation, and the role of identity as a modern security perimeter. Each lesson emphasizes the protected actor or asset, the required outcome, and the evidence that would demonstrate that a control is working.The Microsoft Entra chapter develops a practical map of identity types, authentication methods, and access decisions. Readers compare user, workload, external, hybrid, and agent identities; multifactor and passwordless authentication; self-service password reset; Password Protection; Conditional Access; Microsoft Entra roles; Azure role-based access control; Global Secure Access; Identity Protection; Privileged Identity Management; access reviews; entitlement management; and Verified ID. The explanations identify each capability's controlling function so that adjacent services do not blur together during exam questions.Azure and Microsoft security coverage follows the same decision-centered method. The guide distinguishes DDoS Protection, Azure Firewall, network security groups, Azure Bastion, Key Vault, Defender for Cloud, Azure Policy, security recommendations, secure score, regulatory-compliance views, and cloud workload protection. It then separates the SIEM and SOAR roles of Microsoft Sentinel from analytics, incidents, automation, hunting, and threat-intelligence functions. Microsoft Defender XDR and its identity, Office 365, cloud-app, and endpoint components are compared by the workloads and signals they protect.The compliance chapter helps readers navigate Microsoft trust and privacy resources and the Microsoft Purview portfolio. Topics include the Service Trust Portal, Microsoft privacy principles, compliance offerings, Compliance Manager, compliance score, improvement actions, data governance, Data Map, sensitivity labels, data loss prevention, Data Lifecycle Management, Records Management, Insider Risk Management, Communication Compliance, eDiscovery, Audit, information protection, Adaptive Protection, and Data Security Investigations. The text states what each tool supports while avoiding claims that a product score or assessment guarantees legal compliance.Practice is integrated with the instruction. The guide contains 128 original multiple-choice questions arranged in thirty-two batches of four during production. Every item has one best answer, three plausible alternatives drawn from the same exam domain, an explanation, and a rationale for each option. Correct-answer positions are balanced across A, B, C, and D. Each item is mapped to one or more of 87 coverage objectives and bound to an exact passage in a locked official source. The questions test distinctions and application of public product concepts; they do not copy, reconstruct, or claim access to secure Microsoft exam content.Microsoft product names and certification requirements can change. Readers should use this guide to learn durable fundamentals and then consult the current official Microsoft exam page and Microsoft Learn documentation before scheduling or taking the exam.
