4. Linux is a general term for a class of free-to-use and self-propagating Unix-like computer operating systems. Which of the following does not belong to the advantages of Linux?

The Linux system is an open-source system, which is relatively mature and has a complete set of permissions mechanisms with high security and stability.

Linux system can install semi-rich free web server software, database, web development tools

The graphical interface makes it relative to other systems. It's easy to use, greatly reducing the user's learning cost

Multiple users can own and use system resources individually, that is, each user has specific permissions to their own resources and does not affect each other.

6. SSD solid state drives can be divided into SLC, MLC, TLC according to the particles. Which of the following statements about these three particles is correct?

The capacity of MLC is double of SLC, life is also doubled

SLC using both positive and negative charges, a floating gate memory 1 bit of information, the MLC using charges of different potentials. 1 floating gate memory 2 bit of information, TLC using charges of different potentials. 1 floating gate memory 6 bit of information.

Although the storage capacity of TLC chips has increased, the cost is much lower, but because the performance is also greatly reduced, it can only be used in low-end NANDFlashx related products

Simplified instruction set has simplified the number of instructions and addressing methods to make it easier to implement, the degree of parallel execution of instructions is better, and the efficiency of the compiler is higher.

Displaying parallel instructions allows the processor to execute instructions in parallel according to the compiled schedule without increasing hardware complexity. The architecture is developed from the ultra-long instruction set architecture and has been greatly improved.

Ultra-long instruction set puts multiple instructions into one instruction word, which effectively improves the utilization efficiency of each computing function component of the CPU and improves the performance of the program

22. What is the correct statement about data routing and cluster management in the Huawei Fusionstorage architecture? (Multiple choice)

When the system starts, MDC and ZK interact to determine MC, and the main MDC and other MDCs monitor each other's heartbeats. The master MDC decides who will take over after a certain MDC fails. Other MDC found that the main MDC was faulty and interacted with zk as the main MDC

Query the main MDC when VBS starts, and register with the main MDC

Distributed storage system writes data. According to the LBA from the application layer and the block size, the VBS generates multiple Keys in units of 1MB, hashes the Keys into Partition IDs, and then follows up the Partition to find the main OSD, and the main OSD notifies the partition corresponding to the OSD to start writing data.

When the distributed storage system is created, N Partitions are generated in the space of 2 to the 32th power, and the backup OSD starting write data corresponding to the Partition is generated according to the distribution of the disk.

When the OSD starts, it queries the MDC from the MDC, reports the status to the home MDC, and the home MDC sends the status change to the VB

When the home MDC fails, the master MDC designates one MDC to take over, and at most two pools belong to one MD
