NS0-157 Question #91: Real Exam Question with Answer & Explanation

The correct answer is A: Connect the NVRAM HA interconnects of the HA pairs.. Achieving high availability in a FAS8080 EX HA pair requires both the NVRAM HA interconnect cabling between controllers and multiple host paths to each controller.

Question

To achieve high-availability within a FAS8080 EX HA pair, which two requirements are needed? (Choose two.)

Options

AConnect the NVRAM HA interconnects of the HA pairs.
BConnect multiple paths from the controllers to the host.
CConnect the local node to the partner node's disk shelves.
DEnable auto-giveback.

Explanation

Achieving high availability in a FAS8080 EX HA pair requires both the NVRAM HA interconnect cabling between controllers and multiple host paths to each controller.

Common mistakes.

C. Connecting the local node's cabling to the partner node's disk shelves supports disk access during takeover but is not a primary HA establishment requirement at the same tier as NVRAM interconnects and host multipathing.
D. Auto-giveback is an optional configuration setting that automates resource return after a failover event, but it is not a physical or connectivity requirement to establish the HA pair itself.
