Hay @Dax, Yes it is valid. I used these and studied for a bout a week. Mind that the free version contains about 60% of the questions. The full PDF version has all the questions. I ended up paying for the PDF version. Good luck man.

Q.95: Azure Functions is an example of a paas - Answer should be YES. Also the explanation says Azure Cosmos DB, Azure Mobile Apps and Azure Service Bus as SaaS. Its wrong. Azure Cosmos DB, Azure Mobile Apps and Azure Service Bus as also PaaS. Please check and correct

Question 216 should be B. Reasoning: Input sanitization is the process of validating and cleaning user-provided input so it can’t be used to execute malicious commands, inject SQL, or exploit vulnerabilities. An input like nmap - 10.11.1.130 could be part of a command injection attempt — if an application passes unsanitized input to a shell or system command, an attacker could run nmap (or worse). Sanitization would prevent this. Why not the others? Email message: "Click this link…" ? This is phishing; mitigated by user training, email filtering, and link scanning, not input sanitization. Browser message: "Your connection is not private." ? This is an SSL/TLS certificate warning; mitigated by proper certificate configuration, not input sanitization. Input sanitization is all about preventing malicious or unexpected data from being processed by your application — perfect for the nmap example.
