During the migration of a legacy Python 2 application to Kunpeng, you notice significant performance degradation.
What is the official recommendation regarding Python environments on Kunpeng?
- A . Python is not supported on ARM64.
- B . Recompile the Python 2 interpreter from source using GCC 4.8.
- C . Upgrade to Python 3.x, as recent versions contain extensive architecture-specific optimizations for ARM64 not present in Python 2.
- D . Run the Python 2 code inside ExaGear binary translation.
In the ARMv8 architecture, what is the size of a standard cache line (L1/L2 cache)?
- A . 32 bytes
- B . 64 bytes
- C . 128 bytes
- D . 256 bytes
What is the primary purpose of the Huawei BiSheng Compiler in the Kunpeng ecosystem?
- A . To translate Python code into machine code directly.
- B . To optimize C, C++, and Fortran applications specifically for Kunpeng architectures.
- C . To act as a hypervisor for virtual machines.
- D . To manage Docker containers on ARM.
In the Huawei Kunpeng HPC ecosystem, what is "Hyper MPI"?
- A . A new type of physical network cable.
- B . Huawei’s highly optimized implementation of the Message Passing Interface (MPI), enhanced for the Kunpeng architecture and RoCE networks to scale parallel computing tasks.
- C . A database management system for high-frequency trading.
- D . A tool to migrate MPI applications from Java to C++.
After installing the Kunpeng Accelerator Engine (KAE) hardware drivers, which command verifies that the Unified Accelerator Framework (UACCE) kernel module is successfully loaded?
- A . systemctl status kae
- B . lsmod | grep uacce
- C . lspci | grep crypto
- D . cat /proc/kae_status
In a multi-node Kunpeng HPC cluster, administrators need to batch deploy operating systems via the network.
Which standard protocol combination is typically used for this bare-metal provisioning process?
- A . HTTP and FTP
- B . PXE (Preboot eXecution Environment) and TFTP/DHCP
- C . SSH and SCP
- D . BGP and OSPF
The x86 architecture is relatively forgiving with "unaligned memory access" (fetching a 4-byte integer from an address not divisible by 4), handling it in hardware with a slight performance penalty. ARM architectures can be stricter and may throw an alignment fault (Bus Error).
Which GCC compiler flag can be used to force the compiler to generate safe code for unaligned pointers, albeit with a performance cost?
- A . -mstrict-align or -mno-unaligned-access
- B . -O3
- C . -fPIE
- D . -funroll-loops
When porting C/C++ code from x86 to ARM64, developers often encounter unexpected bugs due to the default behavior of the char data type.
What is the default signedness of char on the ARM architecture?
- A . Signed by default
- B . Unsigned by default
- C . Dynamically determined at runtime
- D . ARM does not support the char data type
When configuring the Linux kernel for a database server running on Kunpeng, which OS page size provides the best TLB (Translation Lookaside Buffer) hit rate for applications with massive memory footprints?
- A . 4 KB
- B . 16 KB
- C . 32 KB
- D . 64 KB
What technology does the Kunpeng ecosystem use to implement Confidential Computing, providing a Trusted Execution Environment (TEE) for sensitive data?
- A . SecGear (based on ARM TrustZone)
- B . Intel SGX
- C . AMD SEV-SNP
- D . SELinux
