The correct answer is A. The system administrator should take advantage of the company's cluster based computing. Password auditing against personal information requires brute-force or dictionary-style comparisons at scale. With 200,000 users and 14-character minimum passwords, the workload is computationally intensive. Cluster-based computing (A) distributes the task across many nodes in…
Question
A security administrator wants to perform an audit of the company password file to ensure users are not using personal information such as addresses and birthdays as part of their password. The company employs 200,000 users, has virtualized environments with cluster and cloud-based computing resources, and enforces a minimum password length of 14 characters. Which of the following options is BEST suited to run the password auditing software and produce a report in the SHORTEST amount of time?
Options
- AThe system administrator should take advantage of the company's cluster based computing
- BThe system administrator should upload the password file to a virtualized de-duplicated
- CThe system administrator should build a virtual machine on the administrator's desktop,
- DThe system administrator should upload the password file to cloud storage and use

Explanation
Password auditing against personal information requires brute-force or dictionary-style comparisons at scale. With 200,000 users and 14-character minimum passwords, the workload is computationally intensive. Cluster-based computing (A) distributes the task across many nodes in parallel, providing the highest aggregate processing power available within the company's own infrastructure. This results in the fastest turnaround. Cloud storage (D) introduces upload latency and shared-resource variability. A single virtualized VM on an admin desktop (C) has very limited CPU resources. Uploading to a virtualized de-duplicated environment (B) is ambiguous and doesn't address compute speed. The cluster is the best fit for maximum parallelism on a time-sensitive audit.
