• Chose A1

  It’s considered a proprietary system because the company cannot access, modify, or patch the vendor appliance themselves, meaning remediation is fully controlled by the vendor. When the organization lacks direct access to apply updates, the inability to patch becomes a vendor‑controlled limitation, which is the definition of a proprietary system inhibitor.

• Chose A1

  A proprietary system is a technology, software, or solution owned and controlled by a single company, keeping its source code and inner workings secret (closed-source). Users typically license it under strict terms, paying fees, and can't freely modify or share it, ensuring the vendor controls updates, support, and features, often for better integration but less flexibility compared to open systems

• Chose A1

  I believe answer is A - Proprietary system. The system is only known to the vendor and we have no full visibility with it.
