Horudhac su'aal kasta8 su'aalo

Jawaabaha iyo sharraxaadaha waxay soo baxayaan markaad qaadanayso kediska.

  1. What does an RDMA-capable bulk data path aim to reduce?
    • Every CPU operation including setup
    • The need to register or protect memory
    • All application failure modes
    • Repeated CPU copying and kernel-path work during buffer transfers
  2. How can an RDMA-capable InfiniBand data path reduce bulk-transfer overhead?
    • By compressing every application buffer
    • By offloading transfers and reducing repeated host copying and kernel processing
    • By removing the need for memory permissions
    • By guaranteeing lower latency for every application
  3. Qiyaastii waa maxay bandwiishkii isku xirka ee NDR InfiniBand ay bixiso?
    • 40 Gb/s
    • 100 Gb/s
    • 400 Gb/s
    • 10 Gb/s
  4. Gudaha RDMA, maxaa 'lammaanaha safka' loo isticmaalaa?
    • Qabashada soo dir oo hel codsiyada shaqada ee adabtarada shabakadu socodsiiso
    • Kaydinta laba nuqul oo kayd ah oo fayl kasta ah
    • Isku-dubbarididda laba GPU-yada hal qalab oo macquul ah
    • Siraynta iyo furista baakadaha si xidhiidh ah
  5. Waa maxay RoCE?
    • Luuqad barnaamijeed cusub oo GPU-yada
    • RDMA oo ka sareysa Ethernet Converged, taasoo u keenaysa faa'iidooyinka RDMA Ethernet
    • Qaab kaydinta kaydinta
    • Nooc ka mid ah isku xirka fiilada indhaha
  6. Sidee ayuu InfiniBand uga dhigayaa dharkeeda mid aan khasaare lahayn?
    • Adigoo tuuraya baakidh kasta oo aad u weyn
    • Adigoo diraya baakidh kasta saddex jeer
    • Adiga oo joojiya dhammaan hubinta khaladka
    • Adigoo isticmaalaya kontoroolka qulqulka isku xirka-lakabka ku salaysan credit-ka si looga hortago qulqulka kaydka
  7. Why must an RDMA application manage registered buffer lifetime?
    • The adapter needs valid authorized memory while the transfer runs
    • Registration proves the data are correct
    • Buffers never need completion checks
    • Registration replaces all queue pairs
  8. Does RDMA mean a CPU never participates in networking?
    • Yes; CPUs are removed from the servers
    • Yes; every control operation is a GPU kernel
    • No; software and CPU work remain for setup and management
    • No; RDMA requires every byte to be copied repeatedly by the CPU
