Consider rewriting to C and then compiling and running with gcc.

NO.175 Intelligent Platform Management Interface (IPMI) is an open standard hardware management interface specification, which defines the specific method for the management subsystem to communicate?

Combined

Embedded

Tiled

Access

NO.176 Which of the following statement about the CISC instruction set is wrong?

About 20% of the instructions in the CISC command system account for 80% of the processing time

The instruction system is huge, with many instruction formats and addressing modes

Both the CISC instruction set and the RISC instruction set are von Neumann structures.

CISC microprocessor has a complex structure, powerful functions, and easy realization of special functions.

NO.177 Server hardware mainly includes, CPU, motherboard, memory, hard disk, PCIe, chassis, power supply, fan, etc. For Huawei RH2288 V5, all components that support hot swap are CPU, memory, PCIe expansion card.

True

False

NO.178 Memory Large pages use larger paging space, which can effectively reduce page table entries and support memory swapping.

True

False

NO.179 What are the types of optical fiber connected optical modules according to the packaging form? (Multiple choice)

SFP

SFP+

SFP28

NO.180 Among the following chips, which semi-custom chip not only solves the shortcomings of custom circuits, but also overcomes the limited number of gate circuits of the original programming device?

CPU

GPU

FPGA

ASIC

NO.181 When engineer A wants to know the current server CPU load when maintaining EulerOS, which of the following commands can be used? (Multiple choice)

iostat

sar

NO.182 The logo of a certain memory module displays the words “PC3L”, what does the “L” in “PC3L ” mean?

The memory module type is UDIMM

Its rated power is 30W

Its rated voltage is 1.35V

The bit width of its memory particles is 64*3 bit.

NO.183 Linux is a collective term for a class of free-to-use and freely spread Unix-like computer operating systems. Which of the following is not an advantage of Linux?

The graphical interface makes meteorology easy to use for other systems, greatly reducing the learning cost of users.

Multiple users can own and use system resources at the same time, that is, each user has specific permissions on his own resources, and does not affect each other.

The Linux system is an open source system, relatively mature, with a complete set of permissions mechanism, and high security and stability

Linux has built-in a wealth of free network service software, database and web development tools.

NO.184 System sub-health detection and preprocessing refers to the recovery of data in advance by detecting the failure and health status of storage media and hardware, thereby ensuring performance and reliability. Which of the following can detect the health status?
1.Hard so failure slow disk, bad block Smart information, the UNC error
2.Network card failure, speed reduction link packet loss, speed reduction, port failure, flash disconnection, packet loss
3.server service control CPU resource exhaustion, CPU frequency decreases, memory failure ALLED CHOPPED CHING
4.the SSD card failure, slow cards, bad blocks, temperature fault, capacitor failure, endurance than ethylene health threshold

NO.185 Which of the following is wrong about engineer A’s understanding of LVS load balancing technology?

The advantage of LVS/DR is that the server can run any operating system that supports TCP/IP, it only needs an IP address to be configured on the scheduler, and the server group can use private IP addresses.

LVS/NAT is the simplest way, so RealServer only needs to point its own gateway to Director, and Director can also be a RealServer

In the LVS/DR mode, the scheduler dynamically selects a server according to the load conditions of each server without modifying or encapsulating IP packets, but changing the MAC address of the data frame to the MAC address of the selected server.

In the LVS/DR mode, Director and RealServer must physically have a network card connected through an uninterrupted LAN.

NO.186 Which of the following applications does not belong to ASIC?

2008 Beijing Olympics LED reel control system

AlphaGo system

CNN structure inference prediction

Atlas 500 Smart Station

NO.187 Which of the following is the correct understanding of the principle of high-availability clusters? (Multiple choice)

The high availability of a computing system is measured by the reliability and maintainability of the system.

High-availability clusters have two working modes, master-master working mode and master-slave working mode.

In a master-slave high-availability cluster, the standby server detects the operating status of the primary server through the heartbeat line. If it cannot detect the “heartbeat” of the primary server, it automatically takes over the resources of the primary server.

High-availability cluster refers to the use of the fault tolerance of the cluster system to provide 7X24 uninterrupted services to the outside world, aiming to provide highly reliable services.

NO.188 Which of the following is not classified according to the network card structure type?

Flexible card

MEZZ card

IB network card
