   A site has two independent power feeds available for a PowerMax 2000. The system has two engine enclosures, each with two power supplies. How should the power cables be connected to maximize redundancy?

   • AConnect all power supplies in the first enclosure to feed A and all in the second to feed B.
   • BConnect both power supplies in the first enclosure to feed A and both in the second to feed A as well, using feed B as a spare.
   • CConnect all power supplies to feed A, and use feed B for other equipment.
   • DConnect one power supply in each enclosure to feed A and the other to feed B.

   A PowerMax 8000 system has a fabric diagram showing that director 1 in engine A connects to I/O bay 1 and I/O bay 2, while director 2 in engine A connects only to I/O bay 1. During a maintenance window, you need to replace a cable in I/O bay 2. What is the impact on data availability if you proceed without any additional changes?

   • ADirector 2 will take over the traffic from director 1 automatically.
   • BNo impact, because director 1 has a redundant path to I/O bay 1.
   • CThe system will reroute traffic through the other engine enclosure.
   • DDirector 1 will lose its only path to I/O bay 2, potentially causing an outage for that director's traffic.

   You are documenting the cabling of a PowerMax 2000 for a customer. The fabric diagram shows that each engine has two directors, and each director connects to both I/O bays. What does this topology provide?

   • AA fully redundant fabric with no single point of failure in the data path.
   • BA high-bandwidth fabric that doubles the throughput of each director.
   • CA simplified cabling scheme that reduces the number of cables required.
   • DA design that allows directors to be hot-swapped without any impact.

   A technician is troubleshooting a PowerMax 2000 with intermittent connectivity between an engine and an I/O bay. The fabric diagram shows that the link is a single cable. The technician wants to replace the cable but the system is in production. What is the best course of action?

   • AIgnore the issue, as intermittent connectivity is not a concern.
   • BHot-swap the cable without any downtime, as the system supports it.
   • CReplace the cable during a maintenance window, as the link is not redundant.
   • DAdd a second cable first to create redundancy, then replace the faulty one.

   A PowerMax 8000 system is experiencing a fabric error on a link between a director and an I/O bay. The service procedure says to replace the cable, but the system is in production and the link is not redundant. What is the best approach to minimize downtime?

   • ASchedule the replacement during a maintenance window and prepare all tools and spare parts in advance.
   • BAdd a second cable in parallel before replacing the faulty one, without any downtime.
   • CIgnore the error and continue operating, as the system can tolerate the fault.
   • DReplace the cable immediately, as the error indicates a complete failure.
