Question # 81

The amount of data operated by the online analysis and processing system OLAP is very large, and a large amount of data needs to be calculated but its timeliness requirements are low, while the online transaction processing system OLTP is mainly used to record the occurrence of a certain type of business events, and the timeliness of the data is very high, therefore OLTP is better suited to use the massively parallel processing architecture MPP. Single selection

TRUE

FALSE

Question # 82

The following description of the application performance management APM data acquisition process, which one is wrong? Single selection

The acquisition probe is buried through bytecode enhancement technology, and the call data is generated

C . APM is the application data collected by the acquisition probe

APM supports collecting application data from a specified journal group

Question # 83

The following description of the database SQL optimization method. which is wrong? Single selection

B-Tree index reduces the operation of the hard disk by 10 according to the query conditions to improve the query efficiency

Reduce large-scale transaction operations in the business, avoid processing too much data in one transaction, remove unnecessary queries, try to ensure that all read operations are necessary in transactions, and reduce the amount of locked data

D . Appropriately increase the cache capacity, increase the cache hit ratio, and reduce the load of the hard disk 10

Question # 84

Which of the following describes the basic concepts of HUAWEI CLOUD LOG SERVICE LTS is incorrect? Single selection

Log streams are the basic units of log management in Log Service, and you can create log streams and set log storage time.

Log groups and log streams can be automatically created in the Log Service console

After the Agent collects logs, it needs to classify and isolate each log data and send it to Log Service as a log stream as a unit

D . Log group is the basic unit of log reading and writing, and log streams can be created in the log group to facilitate further classification and management of logs

Question # 85

The following description of the storage and computing separation deployment, which is the error? Single selection

When the computing power is insufficient, the computing resources can be expanded separately, and when the storage capacity is insufficient, the storage resources can be expanded separately.

It is convenient to " share " data with multiple different clusters

It is suitable for scenarios such as multi-tenant access, long-term storage, and cross-regional data in multiple computer rooms

Hierarchical decoupling of service-oriented architecture, high O & M flexibility

Question # 86

Which of the following is not an optimization practice for low-latency services? Single selection

Use heterogeneous computing resources and use differentiated computing architectures for different types of services, such as GPU and FPGA computing resource pools

B . Use intelligent DNS distribution deployment to shorten network latency, reduce data transmission, and improve efficiency

C . Use relational database service RDS and use database management DAS to analyze SQL statements and obtain the corresponding slow SQL

Statement Discipline Optimization

D . Containerized applications are deployed in CCE clusters, and application performance management APM is used to analyze the call status of applications and optimize the architecture after understanding application bottlenecks

Use the database intermediate DDM to split the database and table, reduce the whole to zero, and reduce the query delay of the huge amount of data in a single database

Question # 87

On HUAWEI CLOUD which of the following aggregation methods is not supported by CloudMonitor CES? Single selection

maximum value

difference value

mean

variance

Question # 88

Customers report that the database response delay is high, the service query is slow, and the CPU usage load is too high during the morning peak. As a solution architect, the architect should prioritize the analysis of SQL statements with a large number of executions, long execution time, and a large number of scan lines in the slow log, and analyze the slow SQL statements through the SQL diagnostic tool in DAS . And act on diagnostic insights, such as creating an index on a keyword segment. Single selection

TRUE

FALSE

Question # 89

A company is an Internet product development company, and the company ' s architect decides to use the grayscale release strategy to iterate the product version, which of the following options cannot be used as the reason why the company adopts grayscale release? Single selection

Teams that adopt agile development, with high release frequency, basically maintain a weekly release frequency

The new version can directly allow end users to test product features

C . System upgrade may be a risk that both old and new versions can be tolerated

D . The answer to the risk of user loss caused by sudden changes in user habits
