Plenty of VPC and CloudWatch questions. Of the three associate level certifications, and after having gone through all three LinuxAcademy courses, I felt that the SysOps exam was the hardest. This is in part due to a much heavier focus on application of knowledge than Solutions Architect and Developer (the most straightforward). The questions are longer and multiple sentences contain supporting and opposing that modify the correct answer. The options themselves are often long and tricky, with easy-to-miss qualifiers that include or eliminate that option in the final answer.
If there's one important tip for this exam, that will be to "Read Carefully Review Thoroughly".
