Question#1

Which standard Linux CLI utility is primarily used to display the status, firmware version, and port states of RDMA (RoCE/InfiniBand) devices on a Kunpeng HPC node?

A. rdma-link
B. ifconfig
C. ibv_devinfo
D. ip link show

Question#2

Which tuned profile is generally recommended in openEuler to optimize the system for high-throughput database workloads?

A. powersave
B. desktop
C. throughput-performance
D. virtual-guest

Question#3

To prevent the Linux kernel's Page Cache from causing double-caching and unpredictable memory out-of-memory (OOM) kills when running enterprise databases (like openGauss or Oracle) on Kunpeng, developers ensure the database uses which standard Linux I/O flag to bypass the OS cache and write directly to disk?

A. O_APPEND
B. O_NONBLOCK
C. O_DIRECT
D. O_SYNC

Question#4

In the Kunpeng System Profiler's Microarchitecture Analysis (Top-Down method), a high "Frontend Bound" percentage typically suggests what kind of CPU execution issue?

A. The CPU is waiting for data to be retrieved from main memory (RAM).
B. The CPU's execution units are overloaded with complex floating-point math.
C. The CPU is stalling due to instruction fetch delays (e.g., instruction cache misses or branch mispredictions).
D. The physical disk I/O queue is saturated.

Question#5

In the context of Kunpeng virtualization tuning, what is a best practice to prevent virtual machines from competing for CPU cache resources on the same physical host?

A. Overcommit the CPU ratio to 10:1.
B. Disable SR-IOV on the physical network adapters.
C. Implement CPU Pinning (vCPU to pCPU binding) combined with NUMA topology awareness.
D. Force all VMs to use IDE emulated disk controllers.
