問題文
A multi-tenant InfiniBand fabric uses partitions. An engineer must state what partitioning actually establishes. Which statement is correct?
選択肢
- It assigns a separate management entity to each tenant.
- It divides the physical fabric into segments so that the links carrying one tenant's traffic are distinct from the links carrying another tenant's traffic, which is what gives each tenant a predictable share of the available bandwidth even when a neighboring tenant is saturating its own segment.
- It describes a set of end nodes within the fabric that may communicate with each other, and it is unrelated to the boundaries that subnets, switches or routers establish.
- It follows the switch boundaries, so every port on one switch belongs to the same partition and a tenant that needs isolation must be given its own switch.
