Hi @Nayeh
My name is Morales and I am from Mexico. I passed this exam last week. I found the exam a bit hard or maybe I was not prepared for it. But majority of these questions are in the exam.
I wish you best of luck with your exam.

208:Based on the scenario described—where an application server's software is behaving abnormally by generating unexpected outbound traffic over random high ports—the most likely exploited vulnerability is:
Memory Injection (e.g., Buffer Overflow or Code Injection)
Why?
Abnormal process behavior (unexpected network traffic) suggests execution of malicious code injected into the software’s memory.
Random high ports are commonly used by malware for command-and-control (C2) communication or data exfiltration.
Memory-based attacks (e.g., buffer overflows, ROP attacks) can hijack a legitimate process to execute attacker-controlled payloads.
Why Not the Others?
Race Condition
Causes timing-related exploits (e.g., TOCTOU attacks) but does not typically generate network traffic.
Would lead to logic errors, not outbound connections.
Side Loading
Involves loading malicious DLLs/libraries, but this usually happens at startup, not mid-execution.
More common in Windows environments (e.g.,

194: To ensure the organization follows security best practices when transitioning an on-premises application to a cloud-based service, the security team should implement all of the listed controls, as they address different critical aspects of cloud security. However, if prioritizing the most fundamental requirement for a secure cloud deployment, the team should first ensure:
1. Virtualization and Isolation of Resources
Why? Cloud environments rely on multi-tenancy, so virtualization and isolation prevent cross-tenant attacks (e.g., VM escapes, side-channel attacks).
Best Practice: Use hypervisor security, container isolation, and micro-segmentation to enforce strict boundaries between workloads.
Supporting Controls (Also Critical but Secondary to Core Isolation):
2. Network Segmentation
Limits lateral movement if a breach occurs (e.g., separating frontend/backend tiers).
However, isolation at the virtualization layer is more foundational in cloud environments.
3. Data Encryption
