Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 878 discussion

Option A doesn't provide the same level of security because it relies on a single email address managed by the company, which could be compromised, and it requires all account owners to access this email account, potentially leading to access control issues. Option B presents a similar issue as Option A, as it relies on different email distribution lists but still requires administrator email addresses that may be vulnerable to compromise. Option C also has security concerns because it associates the root user email address with individual employees, which may not be ideal for security and access control purposes. So, Option D is the most secure solution for ensuring that future notifications can be sent to different employees based on the notification categories of billing, operations, or security.
