What is SHARP designed to do?
Why A is the answer
Run collective operations in the network
Switches aggregate data, which reduces traffic.
In detail
- Switches aggregate data, which reduces traffic.
- Collectives run in the network.
Use case
An illustrative scenario, not a real incident.
Switches aggregate an all-reduce with SHARP, so less data crosses the fabric.

Key point: SHARP runs collectives in the network.
Why the other options are wrong
- B. Encrypt all traffic at the host
- It is not host encryption.
- C. Sync clocks across data centers
- It is not time sync.
- D. Rebuild failed storage volumes
- It is not storage rebuild.
