Exam FlashArray Implementation Specialist topic 1 question 43 discussion

To view the NVRAM install and update status, the command that should be used from the given options is C. purehw list --all. Here's why: purehw list is a command generally used to inspect the status of hardware components within a Pure Storage array. While the provided sources specifically show examples of purehw list --type pwr for checking power supply status, purehw list --all would logically extend to cover all hardware components, including NVRAM modules. NVRAM modules are critical hardware components of the controllers. puredrive list is used for listing information about DirectFlash Modules (DFMs) and DirectMemory Modules (DMMs), including their status and capacity. While some DirectFlash Modules are "DirectFlash Modules with Distributed NVRAM (DFMDs)" and DMMs leverage SCM drives for cache, the dedicated NVRAM modules in controller slots are typically distinct from the drives listed by puredrive list.
