CV0-003 Question #349: Real Exam Question with Answer & Explanation
The correct answer is C: Multipathing. Multipathing in a blade server chassis aggregates multiple physical I/O paths across the chassis midplane into a unified logical fabric, allowing the distributed compute infrastructure to be presented and managed as a single unit.

Question
An organization has multiple blade servers that are managed individually. The organization wants to unify the compute infrastructure and present it as a single unit. Which of the following is implemented to allow this?
Options
- ADatacenter bridging
- BResource pooling
- CMultipathing
- DLoad balancing
Explanation
Multipathing in a blade server chassis aggregates multiple physical I/O paths across the chassis midplane into a unified logical fabric, allowing the distributed compute infrastructure to be presented and managed as a single unit.
Common mistakes.
- A. Datacenter bridging is a set of IEEE Ethernet enhancements enabling lossless transport of storage and network traffic over a converged Ethernet fabric, but it does not unify separate blade servers into a single compute unit.
- B. Resource pooling is a higher-level virtualization concept describing on-demand aggregation of compute resources, but it does not define the underlying physical mechanism used to unify blade server I/O paths at the infrastructure level.
- D. Load balancing distributes workloads or traffic across multiple servers to optimize utilization and performance, but it does not present multiple discrete servers as a single unified infrastructure unit.
