  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. Zvichida kuti ndeipi per-link bandwidth inopa NDR InfiniBand?
    • 40 Gb/s
    • 100 Gb/s
    • 400 Gb/s
    • 10 Gb/s
  4. MuRDMA, chii chinonzi 'queue pair' chinoshandiswa?
    • Kubata kutumira uye kugamuchira zvikumbiro zvebasa izvo network adapta inoitwa
    • Kuchengeta makopi maviri ekuchengetedza eese faira
    • Kubatanidza maGPU maviri mune chimwe chinhu chine musoro
    • Encrypting uye decrypting mapaketi mukutevedzana
  5. Chii chinonzi RoCE?
    • Mutauro mutsva wekuronga weGPUs
    • RDMA pamusoro peConverged Ethernet, ichiunza RDMA mabhenefiti kuEthernet
    • Iyo yekuchengetedza compression fomati
    • Mhando ye optical cable connector
  6. InfiniBand inoita sei kuti jira rayo rishaye kurasikirwa?
    • Nekudonhedza chero pakiti yakakura zvakanyanya
    • Nokutumira pakiti imwe neimwe katatu
    • Nekudzima kutarisa kukanganisa kwese
    • Nekushandisa chikwereti-based link-layer flow control kudzivirira buffer kufashama
  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
