H13-211 HCIA-Intelligent Computing V1.0 Questions and Answers

TRUE

FALSE

Resource decoupling

Single system runs independently and efficiently

Dynamic resource allocation

Realize intelligent scheduling and optimization

The two key points of using data linking are: 1. has two or more database server groups, 2. can provide transparent services

Synchronize the database. After the database client sends a data update request, the node that accepts the request will copy the updated data to other nodes in the cluster while returning the results to the client.

Database cluster contains two models: synchronous cluster and asynchronous cluster

Asynchronous database, the node that accepts the request after the database client sends a data update request immediately returns the result to the client, and the updated data will be copied and transmitted to other nodes in the cluster at a certain time.

The overclocking operation of the PC is usually to adjust the multiplier for the unlocked multiplier CPU. The overclocking method for adjusting the multiplier is much more stable than the external frequency.

The data transmission speed between the CPU and the system is limited, and the blindly pursuit of high frequency and high frequency multiplier CPU will have obvious "bottleneck" effect

Under the same external frequency, the higher the frequency multiplier, the higher the CPU frequency.

The multiplication factor refers to the relationship between CPU frequency and external frequency

Under the same external frequency, the higher the frequency multiplier is, the higher the thing is, without restrictions

The speed of data transmission between the CPU and the system is limited, and the CPU that blindly pursues high principle and obtains high frequency multiplication will have a bottleneck effect of the net legs.

The frequency doubling system refers to the relative proportion between the main CPU item and Waiton

R Guo Zuo is right to adjust the signal frequency of the CFU without indignation. The super state that adjusts the frequency multiplier is quite stable.

TRUE

FALSE

UDIMM, unbuffered dual in-line memory module, the address and control signals go directly to the DRAM chip on the DIM without the buffer, so the price is cheap

UDIMM needs to ensure that the transmission distance between the CPU and each memory particle is equal, so that parallel transmission is effective, and this requires a higher manufacturing process, so UDIMM is lower in capacity and frequency.

Compared with RDIMM. LRDIM reduces the load and power consumption of the memory bus, and provides the maximum supported capacity of the memory

RDIM supports But fered mode and high-performance Registerd mode is more stable than UDIM, and supports the maximum capacity of server memory,

TRUE

FALSE

High availability of the computing system (HighAvai150V is through the reliability (reliabili ty) and maintainability of the system (ma itainmm degree m

High-availability clusters have two working modes: tive active working mode and active standby working voice.

The master-slave high-availability centralized backup service community detects the running status of the main server through a heartbeat line. When it detects the "heartbeat" of the main server, it automatically takes over the resources of the main server.

Two useful heart states use the fault tolerance of the cluster system to provide 7*24 hours of uninterrupted service to the outside

The computing node only provides computing resources such as CPU and memory. The hardware configuration information is stored in the configuration file, and the data is stored centrally on the disk array, which realizes the independence of the network, storage and computing node.

The computing node configuration is saved in the chassis management module, which can be imported and exported. The chassis management module's master and backup are automatically synchronized, and the master and backup are mutually backup.

Stateless computing technology eliminates the dependence on the hypervisor in the virtualization layer, so the database can use the hardware-based stateless computing technology to achieve a low-cost high availability solution

CLOUDSTACK can help users better coordinate server, storage, and network resources to build a LAAS platform

CLOUDSTACK is an open source database software

CLOUSTACK can deploy new services on an unlimited scale and faster
